1. Why is it "beautiful"
Regarding the appearance, the article may initially face a problem: how to objectively, calmly and neutrally express the sentiment "WOW beautifully turned". In this regard, we first list some objective facts:
1. Find X is the only phone on the market that has no openings or bangs on the front and no lens on the back
2. The front side adopts COP high-cost packaging, and the chin is reduced to 3.4 mm after the flexible screen is folded.
3. The screen-to-body ratio reaches 93.8%. In addition to the greater visual impact, the 3D curved screen is also softer and more stereoscopic
4. The back of the fuselage has the same 3D arc surface, which together with the front to create a cobblestone texture; the gradient color of the streamer dots is very pleasing
OPPO said that their original design was not a full screen without bangs, but beauty; Find X has indeed reached new heights in terms of feel and grip-the visual impact of the 6.4-inch screen on the body and the sense of one-handed grip. Among them, high screen-to-body ratio, overall roundness, no front and back sensors, and no lens are the key steps.
2. Pop-up design of lens components before and after assembly
Similar to the vivo NEX, OPPO also chooses a pop-up design, but instead of a front lens, it pops up with multiple parts and sensors in the middle frame. From the front to the back, they are: front lens, micro-slit sound guide earpiece, Face ID facial recognition module, light sensor, rear dual camera, etc. These originals are hidden in the middle frame with a dual-regulation periscope structure, hidden by the rear shell and the screen, and only ejected by the motor when they are used.
Find X has more hidden and liftable parts, which means that the calling scene is more complicated; only from the experience of this period: unlock the bright screen face, turn on the front camera, the rear camera, the entire top needs to complete the pop-up and Retracted. OPPO official data shows: They did a durability test of 300,000 lifts for this module, while vivo's front camera durability test was 50,000. What needs to be important here is that five times the number of times does not compare the technical level of the two. It can only be said that the chance of Find X calling this module is significantly greater.
The entire top of Find X can pop up. The data provided by OPPO is 0.7 seconds; we tried to enter facial data and unlocked through Face ID. The pop-up and retrieval speeds are very fast. However, because the system version is still iterating, there is only a simple motor sound when lifting, which is a bit dry.

In the safety part, the rebound strategy of the entire module is relatively "soft". When the phone is dropped, it will be recognized by the body sensor and retracted; it will also rebound when you press on the top. So the author is not worried about the external force, and their rebound protection mechanism does a good job.
This is the theoretical "dual-regulation periscope pop-up module", and it is also the biggest core of Find X's face value. But "radical design" has gains in one aspect, but it is inevitable that it will lose in other parts.
3. On the gains and losses: the pop-up environment is complex and the space compression technology is challenging
The first challenge is the spatial layout. Due to the extra original parts of the pop-up module, such as partitions and motors, the available space inside the fuselage is smaller. OPPO said that they squeezed 11.2% of the space for this technology. For this reason, they chose two batteries in series, and the SIM card slot has also changed from dual card flat to front and back sides.
Also out of space considerations, Find X made concessions on the lens this time.
"For the sake of image quality, it is reasonable that the rear main lens is prominent," we have said this sentence countless times in other product reviews. However, because the lens of Find X is hidden in the lifting module, there is no room for the thickness; therefore, the main lens parameter part uses the Sony IMX512 + 16 million pixel OIS optical image stabilization main lens + 20 million pixel auxiliary camera. Now IMX393+ The flagship of the second half of the year with dual optical image stabilization is not outstanding. (Of course, the actual performance has to be tested, after all, the same combination is similar, and the performance of OnePlus 6 is quite good)
Dustproof and waterproof has become an unavoidable problem of this design. In addition, the more complicated use environment still leaves us a question mark. Face ID's high-frequency applications for unlocking, shopping and payment, and the pop-up speed of the rear camera all have relatively strict requirements on the durability and response time of the Find X module. Also due to the complexity of the use environment, such as the area of ​​the module card slot is gray, foreign objects stuck, fingers are clamped (we put our fingers in the module slot deliberately and then let it rebound, the module will be stuck there to prevent hands from being caught). The problem requires more careful observation; although the official said, foreign matter and fault tolerance were considered at the beginning of the design.
Fourth, the Android machine finally Face ID
A while ago, the Xiaomi Mi 8 Discovery Edition launched its first Face ID Android device, and Find X became the second. The popularization of Face ID technology in the second half or the end of the year has gradually begun. So we are here, it is necessary for the current advantages of Face ID to be popularized. Of course, we also had a detailed article on the principle of 3D structured light. You can click here: Apple’s Face ID was launched almost one year ago. No
The “Face ID†technology is included in the pop-up design. In principle, the 3D structured light uses a dot-matrix projector that emits invisible light points. At the same time, a lens that can record and identify depth of field information and draw 3D reading points is required. The two cameras operate at the same time to draw 3D facial images. There are two obvious benefits of this:
1. Infrared light can be used even when the outside is completely dark;
2. The 3D depth of field information can easily see through the photos on the plane and improve the safety.
And the accuracy level of structured light is 0.1 mm, and the accuracy of biometric recognition is higher; this is also currently only Face facial recognition can perform payment-level operations, and the remaining facial recognition can only be used to unlock mobile phones.
Specifically, Find X, compared with the well-known iPhone X, has half the structured light points (Find X is 15,000, Apple is 30,000); it can also be used for payment recognition. When inputting facial information to test the unlocking effect, Find X puts the two together from the camera pop-up to the successful unlocking, and there is no sense of delay or even the speed of unlocking; due to the optimized unlocking animation, it feels that the unlocking speed is faster than Apple.
It is relatively regrettable that Omoji (a facial animation function that can be guessed by looking at the name) cannot be used in the beta version at hand; for this reason, the photographing part was also taken in this experience. You can look forward to the follow-up Detailed evaluation.
Reviews:
"You must have something" has long been concluded in the mobile phone industry: some manufacturers focus on black technology-top quality in all aspects, but the body is thick and not flexible; some manufacturers have conservative plans, with bangs in the front, and face value only on the back work hard.
OPPO's design idea this time is "beauty", so it has a lifting module with a slightly more complicated interactive logic. This is a great innovation in engineering structure and craftsmanship. In addition to products, it is also an improvement to the brand; of course, the Find series has returned for many years, and there is a belief bonus.
How important is appearance? It may have to change to a different context to think. In the store, no matter how many technical bonuses are promoted, the good-looking and technological sense at first glance is undoubtedly the most moving; not to mention the overall pop-up design of Find X with the back arc, which originally has a strong sense of fashion and hints of the future. ; The overall parameters were originally flagship. This kind of cute "personal design" is probably something consumers can't resist. (Wang Di)
Advantages: high appearance, technological sense of pop-up design, flagship configuration
Disadvantages: module pop-up durability needs to be considered, camera level to be tested, no NFC and wireless charging
Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
