Seeing the number of characters, the landlord was scared by himself and he decided to use this map as an outline of the article. Or does the landlord hold a pseudonym from a literary arts? Unfortunately, the landlord does not name Shen ah. Well, no joke. The article is longer. Please ask the officials to prepare their own peanut pudding with eight-treasure porridge, beer and mineral water, dumplings and noodles, and don't eat rotten dumplings. I'm sorry, the landlord ran off again and closed.
I. Introduction
This is the highest-valued public measurement product that the landlord has applied for so far. We must first thank Zhang Aunt for the trust!
Only half of the text of the landlord's test report was written, and he received notification from the unit to go out for a period of time. I was thinking that I couldn’t delay the submission of the report. I took the micro-projection, the original remote control, and the charger during the study. I also brought a camera and an octopus bracket, but I didn’t bring the original data cable that I thought I wasn’t supposed to have. It is precisely this line that left the landlord in vain for a half-month (in which the reason for the article is detailed), and the landlord himself wrote the report is relatively slow, so that the landlord fell to the point of the last report of the public measurement. Here, the landlord apologized to Xiao Bian for his sincerest apologies! ! ! The testimonials of the previous few valued friends have all been read and written by the landlord. The time and the level of photography are spelled out. They can only be spelled out. Friendship reminds you to see if you are not an audience for such products (for example, if you have a group of home theater enthusiasts who are not bad enough to emphasize the ultimate audiovisual experience and are not accustomed to high-definition audiophiles), please click on the upper right corner. However, the report was submitted so late that it must have been missed.
Due to the large time span, the pictures were not taken at the same time, and the background may not be uniform. The landlord's Wisconsin T7000+ monitor was a bit of a problem lately , and the dark part was dead and black without details. Only the gamma value driven by the graphics card was adjusted to 1.4 after the dark part. Can see, but this has brought a series of problems such as contrast is too low, color grade transition is not smooth and high light blinks (Jingdong after sale a month after the return to the factory is still the same, is it the video card driver problem? Do not know in the universal Zhang Whether the aunt can encounter value-friends who can help solve the problem , so the photo contrast, exposure, etc. are adjusted inaccurately (projection brightness and picture test part of the picture are specifically tuned in the unit), see official with their own goggles it .
Second, about the micro-projection
Talk about the landlord's own experience first. When the home was renovated the year before, the home theater was taken into account. Later, because of the tiredness of the decoration, and the fact that the budget was not enough, they did not want to make up for the purchase of low-end equipment and gave up. When the TV background wall was completely reserved, the curtain slot was not reserved. (later infinite regret), in short, is not yet on the road to fever on the dead. After I checked in, I always watched the HD on TV. I didn't think the screen was big enough, but I thought it was nice to make up for it for a while. Screen this thing, really look smaller, after more than a year I would like to buy a projection. However, this time the idea is more realistic, because there is no reserved slot, and no preparation for spending too much money, just want to experience the feeling of a big screen, so it is not going to engage in regular home projection. Happened to a group of friends mentioned a DIY micro-projection, watching screen shots and evaluation is not bad, plus other DIY products to buy before the experience is very good, open booking without a brain when the reservation (yes, but also to book, And the time is not short. The result is that after several months of waiting (in the meantime missed the N multi-brand machine discount), it is indeed a mixture of unpleasant combustible gas discharged from a group that does not match the price. Careful eye maker and nursery, castrated hardware and software, terrible Andrews system, red to sad color cast, rough aluminum shell cutting process, hey, do not want to repeat the table, let it be my heart forever faint Pain. However, during that period of time, they often bubbled up the jars, and compared with the micro-investment products purchased by colleagues and friends and their own negative experiences, they had a little understanding of micro-projection products and their own views, which laid the foundation stone for this successful trial. Be blessed by the curse.
Micro-casting in the eyes of many players in the end there is no market for toys? We use the data to speak. According to the "China Household Intelligence Market for Micro Intelligent Investment Report 2015" published by Analysys Think Tank, the total volume of China's home smart micro-investment market in the first quarter of 2015 was 86,200 units, and it is estimated that 555,000 units will be shipped throughout the year. The histogram shows that the shipment growth is still very fast. If there is any doubt about the accuracy of this report's figures, it can be seen that the sales of micro-investment products by major e-commerce companies can also see the market for such products.
Who will micro-invest to sell, or who will buy micro-investment? Both are called projectors, but some are commercial, some are civilian, and civilians are also high-end, low-end products targeted at high-definition fans. Micro-projection products, due to hardware and volume constraints, are currently more effective than HD fans. The low end is much lower. In fact, these products have their own audiences. The core of micro-investment is "mobility." A large part of the audience, I think, should be a young renter who is not satisfied with the small-screen experience of computers and tablets. Traditional TVs are expensive and they are expensive to carry. Inconvenient, they desperately need a mobile-friendly large-screen video and audio solution, and their own micro-projectors for Android are just right. The landlord recently discovered that some open-air food stalls at night have also started to attract customers with micro-casting live broadcasts and movies, which is also a good application direction of micro-projection. Some users have higher requirements for outbound use, which requires micro-projection products to be more portable, and to have built-in power supplies, so that products that are more mobile-oriented, such as PaPa, are subdivided. The above is the landlord's understanding of micro-casting. If there is anything wrong, please correct me.
Three, about PaPa
Let's first understand the brand under PaPa (official website here). Speaking of PaPa, we must first mention the founder Wang Long. Wang Long was the director of Intime Wireless Division. In February 2014, he joined Cami Technology as CMO. He is fully responsible for brand communication and product sales, helping to popularize the concept of “mirrorless super TV†in the industry. After he left the post, he established the elephant race and fully invested in PaPa's product launch and team recruitment. PaPa's pioneering direction is mobile entertainment. The entry point is the entertainment terminal for young people. These are embodied in the PaPa's first product.
The number of friends who knows the number of meters should be more, and it can be considered as the leading enterprise in the domestic micro investment field. According to the "China Household Intelligence Market Research Report 2015" published by Analysys Think Tank, in the first quarter of 2015, the total number of domestic smart microfinance market shipments was 86,200, and the market share of polar rice was 49.0%. PaPa did not The current strength of the list is still relatively large. The brand popularity of Lami has also contributed to the founders of PaPa. Whether they can catch up here is the first question mark (both crowdfunding and early sales are missed by the landlords, and they are not optimistic about the current marketing scale and sales volume).
At first, PaPa's micro-projection was seen on crowdfunding. At that time, the resolution was automatically ignored and no attention was paid to it. In all fairness, if you choose to buy micro-investment products, the landlord will never be included in this alternative list. Thanks to Zhang Aunt, let me come into contact with this product and find some highlights.
Look at the parameters (generally made by the micro-projection brightness and contrast virtual imaginary, probably look at other parameters on the line) and introduction (product promotion in the "theater" and "office" word is not quite agree with the landlord), PaPa positioning should be Look at online streaming media, playing screencasting, and portable, entry-level micro-projection products. This configuration and price audience is also an ordinary consumer who does not have too high a display requirement. I think the focus of this product evaluation is not the same as the projection resolution (users who purchase such products in the forums are very low compared with HD enthusiasts, of course, the evaluation still has to say A bit), the degree of portability, ah, heat, noise, ah, brightness is enough, ah, there is a large cast color ah, the system's ease of use ah, video format compatibility ah, compatibility of external storage devices, ah, Ah, power consumption, battery life, and the like are the potential users of this product are more concerned or directly affect the use of points , PaPa to do these aspects, even if successful. Therefore, the focus of this report is also in these areas.
Fourth, the product is out of the box
On the last day of the September holiday (when the nuclear manuscript saw that it was really embarrassing, and it took more than a month before submitting the report), she received a phone call from Shentong's younger brother. I knew that it was definitely PaPa, and immediately came downstairs to get it. The district's courier concentrated distribution points, in a number of parcels at a glance, Aunt Zhang's recognizable Queen's Royal Tape, straight to the pick-up to leave, do not take away a cloud.
The parcel feels light in his hand, once suspected that Zhang Ama is sending the wrong goods. Is there really a projector inside? Although it is known that this is a portable micro-projection, is it really so light? Therefore, on the way back, the landlord could not wait to lift the seal of the aunt. After opening the corner of the bubble buffer bag, he saw a white box with the word "Pa" printed on it. This relieved him. As a result, the product's portability has been added to my heart.
PaPa's packaging uses a very popular minimalist style. The box is white, with only a dark red stamping LOGO in the middle.
On the back of the box, information such as device parameters, functions, and social platform entrances are printed.
The box is a regular up-and-down buckle type packaging. Open the box, the inside is still concise, the body of the milky white body is trapped in the rounded square groove that is matched with it, next to it is a neat black inner box, black and white shines, simple but not monotonous.
Inside the black box is a charger, data cable, manual and remote control.
The family portrait is here.
First of all, the next part of the accessories, some with evaluation (will not be described in detail below) , the fuselage details in the next part.
The charger uses the 5V 2A output that is relatively common at present, and the data line is a white Micro USB cable.
Thick millet wind remote control.
The appearance of the remote control is simple and comfortable, but it is inconvenient because it is too simple and practical. Fortunately, the PaPa preset "Goku remote control", with its own remote control has been idle. In addition, if you change the remote control from infrared to Bluetooth is better.
The remote controller uses a 2032 button battery. The first time you use it, you need to pull out the insulating gasket. 
This is a tripod with a small box, 2 can be drawn out of the structure, with the tripod I bought in 2007 to send the card machine is the same, Taobao prices are generally below 10 yuan (here to Tucao about 39 yuan official website pricing) . The workmanship was generally full of cheap feeling. My table was cut off, but considering the PaPa's weight, the tripod was still within range.
Fifth, the fuselage details
PaPa's body design still continues simple style: round square, edge chamfered, size 10x10x2.5cm, is equivalent to the ordinary Andrews box, the volume is very small, weighing only 230 grams, one hand grasp without pressure (landlord's hand Smaller in men, friends of other values ​​should be even smaller in their hands, and portability is very strong, which is PaPa's biggest selling point .
PaPa adopts the glass and metal materials commonly used in current high-end mobile phone models. The top of the fuselage is covered with a layer of milky glass panel (itself has a fingerprint collection property, but fortunately the color is not easy to see), and the champagne color is used around the body. Aluminum alloy material.
In order to ensure the visual integrity, all buttons on the top of the fuselage are designed as touch.
PaPa has a total of 8 touch buttons, in addition to the usual red power button, for the overall aesthetic, up, down, left, right, OK, return, home page 7 keys are hidden attributes, visible after the device is turned on, the design is more clever.
The backlight of the hidden buttons is weak and cannot be seen under normal lighting conditions.
PS: Long press "up and down" function is to add or subtract volume, sometimes easy to press.
Aluminum alloy metal frame around the fuselage is a one-piece, the color is a bit similar to Apple's local gold. The edge uses CNC cutting chamfering technology, which is closely attached to the panel without burrs and large gaps. The workmanship is more refined.
The left side of the projector is a projection lens. The design without a dust cover is slightly regrettable. Take care when protecting the lens.
The infrared sensor is on the right side of the front. Since the projection device is not normally used on the machine during actual use, the effect of switching to a Bluetooth remote control may be better.
The left side is respectively put on the left side (Official icon note as "sound", the actual effect is limited to sound, but also can not keep up with the phone) and focus adjustment knob.
The right side is a row of cooling holes to facilitate the timely distribution of the heat generated by the projection lamp to the outside of the fuselage. The edge of the opening is meticulous and satisfactory.
The back of the machine is 3.5mm headphone jack from left to right, TF card slot (up to 32G) , standard USB 2.0 port, Reset hole (pressing about 5 seconds when abnormality occurs), Mirco USB port (charging/data transmission).
Unfortunately, PaPa does not have any video input interface , which means that it cannot be directly used as an external display device. It must rely on the same screen projection method.
The bottom of the machine is a large area cooling hole and a standard camera tripod hole, and four corners also have non-slip foot pads.
The cooling hole is the cooling fan. Such a small machine heat dissipation is the primary consideration, PaPa does a good job in this area , there is no problem of overheating and automatic shutdown in actual use; fan noise control is also good , use the ceiling in the bed at night, the machine on the ear The side is also relatively quiet.
Summary: PaPa glass and metal combination of high body color value, compact and lightweight design brings a very good portability, and thermal design considerate, but there are also missing lens cap, virtual button backlight brightness is insufficient, no HDMI Interfaces, etc.
Sixth, the official use of tutorials
At the beginning, the landlord did not pay special attention to the official micro-information printed on the bottom of the box, and he did not visit the official forum. Therefore, he did not see the official tutorial and used a detour (such as the landlord did not know the screenshot function How to operate). Therefore, the landlord felt that it was necessary to share the official tutorial link with everyone here.
PaPa Pocket Theater Tutorial No.1 (Basic)
PaPa Pocket Theater Tutorial No.2 (File Transfer)
PaPa pocket theater tutorial No.3 (Apple mobile phone with the screen)
PaPa pocket theater tutorial No.4 (Android mobile phone with the screen)
PaPa Pocket Theater Tutorial No.5 (Video Operation)
PaPa pocket theater tutorial No.6 (flying mouse remote control)
Summary: The official use of the tutorial is illustrated, simple and straightforward, easy to understand, and covers the common usage, even if the novice can start quickly.
VII. System Description
PaPa does not have an HDMI interface and cannot be connected to an external input device. Therefore, whether or not the system is stable and excellent has a great influence on the experience, so it is introduced as a separate part.
Shutdown status Tap the power button, the backlight will light up, long press the power button to boot.
The boot interface is also a brand LOGO with a white background.
It takes approximately 40 seconds to load from the press of the power button to the main interface. The boot speed is not fast.
PaPa uses a system based on the Android 4.4.2 shallow customization .
The main interface uses the current card style commonly used in the Android box. The main functions are on the main page. The logic is simple and the rules are quite satisfactory.
If the desktop card can be customized, adding "one-touch direct", "a key to clean up memory" and other functions, I think it will be more easy to use. (PS: The landlord experience has replaced the desktop with the sofa table.)
The apps used by the "Movie" and "TV" cards are "Thailand" and "Television".
Value friends using the Android box should understand that both are live and on-demand aggregation APPs, and the functional distinction is not so obvious. Perhaps it is because the fluency of the TV cat's own live stream is currently slightly stronger than that of Tai Jie. PaPa did this sort of thing.
The APPs used by the "games," "app market," and "file management" cards are the "Grape Game Room," "Chippo Market," and "White Paper Manager."
The "Wifi Setup" interface has been optimized for remote control operation. Selecting the SSID up and down and filling in the password can all be accomplished by remote control (it is very tedious to fill in the password by remote control).
After entering the "System Settings" interface, we can see the residual Android native style.
The "System Settings" interface focuses on the "Display" settings that are closely related to the projection function. Other Android Universal Settings do not require more ink. 
"Screen Zoom" can set the projection screen size and ratio.
The arrow keys of the remote controller assumes the function of horizontal and vertical scaling in "Screen Zoom" and cannot move the cursor to the projected ratio icon (PaPa 1.2.0.2 firmware cancels the function of long-pressing the remote control home button to turn on the mouse mode) , so it can only be solved by other means (solutions are roughly two, one is an external mouse device, the second is the use of remote control APP through the phone remote control. PaPa built-in "Goku remote control" APP, built-in mouse mode, download the phone side After APP, you can use your mobile phone as a mouse, which is the daily use of the landlord.)
The "background picture" is the name suggests is to change the desktop wallpaper.
"Brightness" adjusts the brightness of the system. The best suggestion is to keep it bright, because the projection brightness is originally a short board for PaPa, which will be mentioned later.
"Font size" adjusts the font size of the system.
The default font size is large, because the PaPa resolution is only 854480, personal advice or not transferred to the "large" below, otherwise the font's grainy sense is stronger, the smaller the word simply can not see.
"Automatic direction adjustment" as the name suggests is based on the direction of the machine automatically adjust the screen display direction, 0 ° and 180 ° adjustment.
The following four options are the projection display modes, which correspond to the four installation methods of the projector. Since the PaPa is portable, the most common method is "desktop projection." I think almost no users will use the PaPa to lift it. The rear projection is even more impossible, but it still shows how the various methods are placed at the machine level. (also known as "desktop projection") display effect.
There is no "trapezoidal correction " setting in the "Display" setting, which is a pity.
The landlord would like to mention "screenshot settings".
In the beginning, the landlord searched through the instructions and did not find the relevant instructions for the screenshot. He touched the common screenshots of Android phones on the touch buttons and the remote control and tried it again. Afterwards, he saw the official tutorial to know how to use it. . This function is a little hidden, so if you don't use a mouse device to operate the projection, you will never find it.
Hold down the mouse's ok key/left mouse button, swipe up from the bottom of the screen to display a row of virtual keys, and the second icon is a screenshot (we can set whether or not to display this virtual key in the “screen capture settingsâ€), click the icon You can take screenshots and save them by default in the screenshot of the fuselage.
Similar concealment features include a drop-down notification bar. The effect of pulling down from the top left and top right of the screen is as follows.
And open the list of recent programs.
Based on the above, the landlord felt that the squirrel should be the standard for the PaPa. PaPa official mall in the sale of a full keyboard squirrel, priced at 199 yuan, 100 yuan Taobao full keyboard squirrel a lot, the personal feeling of low cost, the landlord belly black speculation 1.2.0.2 version of the firmware cancel long-press remote control home button Does the mouse mode feature also relate to the sale of the mouse? Hey, it's too dark. Maybe it's a bad experience. Cancel it.
In addition, PaPa's built-in "play bucket" (the new version has been renamed "Legendcast Screen") and "WifiDisplay" are two screencast APPs, with AirPlay and Miracast wireless screencasting capabilities, respectively corresponding to IOS and Android platforms, users can put Android The screen of the Apple device is projected onto the machine.
The landlord is not running a party, and the products such as mobile phones, tablets, and computers purchased by him are never run. However, since it is a complete evaluation, it still cannot be excused. Post the security Bunny Run points for everyone to be a reference, personal feeling is not significant.
Finally, posted a comment on the landlord recorded system, recording conditions are generally poor, the value of friends to see the content is enough, do not do projection quality display.
Summary: Although PaPa has a normal boot speed, the actual operation fluency is still good. The UI is simple and clear, but the optimization of the remote control operation is generally similar. Its operation mode is more similar to mobile phones and tablet computers. It is still somewhat distanced from the Android TV system for remote operation. It brings some inconvenience to daily use. Fortunately, it needs to be used. Mouse device operation is not a common function. PaPa comes with comprehensive application coverage. However, whether it is a video game application or a tool application, PaPa is basically a popular third-party solution on the Android box. There is no self-built content platform, let alone its own ecology. Circle. At this stage, the PaPa team is still in the stage of selling hardware. The benefit of doing so is to directly take the quality of others and ensure the quality and also save operating costs. However, everyone also knows that the current Internet economy sells content, and only selling hardware will eventually be led by other families.
Eight, product experience
(A) The lack of off-axis
After the landlord turned on, he found that the micro-projection did not have an off-axis function.
With the off-axis function of the micro-projection, the projected light is based on the plane where the projector is located. All light is above the plane and the image presented is also above the plane. The advantage of this micro-projection is that it can be used without brackets, and the projected image will not be blocked by the placed plane.
The PaPa projected light with the center of the lens as the axis, and the light was cast on the axis. The bracket must be used when using it, otherwise the complete image cannot be dropped on the desktop.
The lack of off-axis function brings more inconvenience to the daily use of PaPa. In addition to being placed on the edge of the shelf, it can not be used out of the shelf. This is PaPa selling point—a minus item for mobile use . Maybe manufacturers are also pursuing the pursuit of compact size. In fact, if the landlord thinks that he can join the off-axis light path, even if the size of the machine is larger, he can accept it.
(b) Projection brightness
In view of the serious deficiency of domestic micro-projection products, especially the brightness, the specific parameters are not further studied here. (The official parameters below 2,000 lumens are not equal to say, er, the reason for not investigating is actually that the landlord did not measure equipment.) Everything speaks with actual experience.
Take a look at the daylight projection effect.
In cloudy daylight, the restaurant is relatively dark and the white latex paint wall is approximately 2.4 meters away.
In cloudy daylight, the restaurant is relatively dark, with white latex paint walls, approximately 1.5 meters away.
In cloudy daylight, the restaurant with relatively dark light, white latex paint wall, is about 0.5 meters away.
On cloudy days, the bedroom is shuttered with a light blue-gray latex paint wall, approximately 1.5 meters away.
On cloudy days, the bedroom was shuttered and covered with a white latex paint wall, approximately 2.2 meters away.
Guizhou has never seen sunny weather, so there is no sunny test.
Night projection effect.
Turn on the lights at night (35W bright white LED), restaurant white latex paint wall, distance of about 2.4 meters.
Turn off the lights in the evening, restaurant (close to the kitchen with a glass door, a little outside interference from the kitchen, not black) white latex paint wall, distance of about 2.4 meters.
In the evening, the restaurant turned off the lights in the kitchen, and the white latex paint wall was about 2 meters away.
In the evening, the bedroom was shuttered with a touch of blue-gray latex paint, approximately 1.7 meters away. 
In the evening, the bedroom was shuttered and covered with a white latex paint wall. The distance was about 2.2 meters.
It can be seen that the projection brightness is another major shortcoming of PaPa . Under normal lighting conditions, unless close to the ground, it can hardly be used normally. In a totally dark environment (walls, paintings, etc. have reflections, the average family can not be completely black), and the brightness of the screen within 2 meters is relatively good. The brightness of 2.2 meters is also generally acceptable.
For those who have previously seen the value of the bracket for the PaPa public survey, we would like to admire it. As mentioned before, there are no curtain slots and no curtains installed; home space is limited, and the landlord is lazy. If you buy a bracket curtain, you must be too lazy. Each use is incorporated, so the evaluation of the effect of the projection of the curtain is not available.
(c) Projection size
PaPa's lens is fixed focus, can only adjust the projection size by changing the distance between the body lens and the projection surface. The official data is that 2 meters can project 74 inches and 3 meters can project 100 inches. The landlord actually measured the projected dimensions of the distances of 1 m, 2 m, and 3 m. The tool only has a tape measure and may have a large error. It is for reference only.
At a distance of 1 meter, the measured projection screen diagonal length is approximately 96 cm, ie 37.80 inches; at a distance of 2 meters, the measured projection screen diagonal length is approximately 188 centimeters, ie 74.02 inches; a distance of 3 meters, measuring projection screen The length of the diagonal is about 255 cm, which is 100.39 inches (given that the brightness of 3 meters has affected the perception even though it is dark, and personal feeling is of little practical significance), which is basically consistent with official data.
As mentioned above, the "soft" adjustment of the screen size can be made in the "display - screen zoom" setting, that is, the size of the display screen can be adjusted by the software within the physical projection size range, and it can also be understood that the screen size cannot be increased. Digital zoom. The landlord feels that adding a simple "trapezoidal correction" setting is not too difficult. In practical applications, "trapezoidal correction" can reduce the restrictions placed on the body, which is far more practical than "screen scaling".
(4) Focusing problem
There are two common focusing problems for micro-projection products. One is virtual focus, and the other is coke. Let's take a look at PaPa's performance:
1. Virtual focus
PaPa does not have the auto focus function. After turning on the power, the focus adjustment knob is needed to manually focus. When focusing, we will find that no matter how you move the focus adjustment knob, the left and right sides of the PaPa projection screen cannot be clearly displayed at the same time. This is the virtual focus. In terms of DLP micro-projections that the landlord has contacted, virtual focus is a common problem. This is also the current shortcoming of DLP technology, which can be improved through projection lenses, but it cannot be completely avoided.
The quality of the projection lens adopted by PaPa is general. From the above several diagrams, it can be seen that there is a more obvious virtual focus (唉, aunt's thumbnail), and potential users who are mainly used for text presentation may be disappointed. If you look at the video, the resolution of the PaPa itself is not high, and when we watch the video, the line of sight is usually concentrated in the middle of the screen. The surrounding virtual focus has a relatively small impact on the actual viewing experience.
2. Coke
The so-called jog is the blurring phenomenon caused by the accumulation of heat in the machine and the thermal expansion and contraction of the lens after the focusing is completed and the projection is used for a period of time. So, the production of coke is closely related to the projected light source heat, lens material and heat dissipation performance. In general, the use of resin lens micro-projection products are more serious than the focus, the use of the process requires us to focus on the second, the use of glass lens products will be much better.
The landlord did not find the material of the lens used by PaPa. He asked the official micro and official QQ group (only 24 people) to disregard it; if he saw the public number saying that there was a user exchange group, the group number was ignored and people felt that this was already an issue. Forgotten gas products. This is the first time that the landlord has written a public test report without any interaction with the official. The landlord found some jog in use, presumably should be a resin lens. However, the brightness of the PaPa is limited, the power of the light source is not too high, and the heat dissipation also passes, so running out of focus is not serious. It only has a slight influence on the text part and has little impact on the video.
Finally, when the focus adjustment knob is rotated to focus, the lens will be slightly displaced; the focus system uses a gear structure, and the density of the gear has a certain influence on the accuracy of the focus.
(5) Screen effect
Friends who know the value of projection know that the screen shot does not accurately reflect the actual effect of the projection, but there are no other more effective means of display, so the landlord did. Limited to equipment and photography technology, for reference only.
The landlord recorded a screen test video with glory 6 plus.
Screen test screen photo.
Unlike the reddish and serious micro-projection that the landlord purchased before, the PaPa projected image does not have a particularly obvious color cast. The audience for micro-projection products should be acceptable.
Zooming in can see the lattice arranged in a diamond shape, demonstrating that the DMD is a diamond array. PaPa was originally a product of grounding gas, and more technical sciences on DLP would not be developed. Valued friends have their own Baidu or reference station for excellent measurement reports and sun bills on DLP projection.
Regarding the resolution of PaPa 854480, the actual effect was not as bad as the landlord imagined when watching the video. The effect of lying on the bed and the wife to see the drama and the variety show was still acceptable. Taking into account the PaPa's positioning and actual use scenarios, the landlord felt that the PaPa's resolution was basically sufficient. Compared with the lack of brightness, the rate of difference should not be considered too short of the PaPa, of course, without a substantial increase in volume. Under the premise of upgrading to 720P is even more icing on the cake.
During the study period, he accompanies his colleagues and uses PaPa to watch a good live broadcast. His colleagues are very curious about PaPa. They are also very good at evaluating the viewing effect (small, convenient, unobtrusive, and good). Willingness to purchase. Colleagues themselves are not pursuing high-definition, I think he also represents a large part of the general consumer groups. The landlord also found that the PaPa was even equipped with the B function.
(6) Data Line Compatibility
Also mentioned above, the landlord did not bring the original data line during the study period, and he brought a Nokia data cable, an LG Viagra cable, and a MiLi HX-T25 OTG multi-use data cable, which are not too bad data lines. Well, the results are not very compatible with my PaPa. It is a bad connection. It is difficult to charge the power (the landlord only successfully charged once during the learning period). Repeatedly in the boot screen cycle, after the boot, there is even a problem with the data line. . The instructions in the manual reminded us to use the original charger and data lines, chargers needless to say, after all, not every mobile phone charging head is 5V 2A output, and the data line landlord I did not think so much ah. Once the landlord thought that this product was defective, he wanted to contact Xiaobian for repair. However, when he thought about it, the data line was not original. If the data line is incompatible, isn't it hard for the Xiaobian? So I have been able to tolerate the return of learning. I used the original data line to test it. The contact was good and the charging was normal. The other problems mentioned above disappeared.
Post a few question videos recorded at the hotel.
Don't know that other value-friends who participated in the test have encountered data line compatibility problems? It stands to reason that the versatility of the Micoro USB data cable is so strong that there should be no compatibility issues. The landlord really hopes to be his own individual problem.
(7) Compatibility of charging equipment
PaPa's compatibility with the charger is still very good, the landlord's Huawei glory 6 plus 5V 2A charger, Samsung Note 3's 5.3V 2A SL version charger and several 5V 2A's unknown charger can give PaPa normal Charging, millet that 16000mAh charging treasure can also PaPa normal charging, of course, not to mention the original charger. Of course, the premise is to use the original data line. . .
Since the mention of the charging treasure, the landlord reminded, must use more than 2A output charging treasure to PaPa charging.
When the landlord used the charger to cast the ceiling, he felt that the data line was too short. He added a 5 meter USB extension cable with a signal enhancement function to cover the five-meter USB extension cable, and the attenuation was too great to be charged. The extension line is fine, here to mention.
In addition, PaPa can be used as a charging treasure. Under the off state, tap the on key to flash, and then output. The landlord tested the output of Glory 6 plus charging.
Friendly reminders, PaPa's battery is used to stretch their own, this feature we all better ignore it.
(8) Playability
1. Local play
PaPa's own player has different open modes and different functions. When we click directly to open and open it with the ES file manager, we temporarily call "Built-in player 1" and open it with the white file manager. We temporarily call "bring player 2".
The function of the built-in player 1 is quite complete, enough for everyday use.
The function of the built-in player 2 is relatively simple.
After sampling, through the U port connected to the storage device, the landlord downloads 1080P BD-Rip movies (sizes ranging from 10-20G) played smoothly with their own player, DTS audio can also be decoded (at present many Android boxes because of copyright The problems are all castrated by DTS hard decoding); BD-Remux and ISO Blu-ray discs have good playback fluency with their own player (3D original disc can be played in 2D), which makes me overjoyed, especially the latter, the landlord The beginning is completely unexpected (testing 1080P BD-Rip with this resolution machine has been drunk, testing the original play is really rogue ah). The 720P BD-Rip, WEB-DL, and small-format packaged movies are more than nothing. In addition to MKV, MP4, RMVB, AVI, VOB, M2TS and other common encapsulation formats are more perfect.
The following is part of the playback screenshots, comes with screenshot function can not intercept the hard solution screen comes with player 1, but the landlord is guaranteed to play normally; own player 2 screen capture normal.
4K can not be hard-solved, the soft solution is stuck (software solution with player 2 can cut off the video screen).
This can't be demanded more. After all, PaPa's resolution is limited, and it can't support 4K.
