Compared to other 3D screen, LED display screen 3D pixel may emit light by itself, have higher brightness, more vibrant colors, higher contrast, and other characteristics of ultra-thin, and has a natural and comfortable field of view wider viewing angle, in Many specific places have broad prospects. Today, the small-pitch screen plus 3D technology, to achieve a better display effect, accompanied by 3D technology innovation, is now gradually making up for the naked eye 3D technology in the LED display application of the scale, but also opened up for 3DLED potential.
LED display manufacturers are keen on 3D technology, using 3D technology to achieve application breakout
With the increasing use of LED displays, people are increasingly demanding them. Now people can't satisfy the two-dimensional flat display, and they hope to truly restore the real-world three-dimensional information. Therefore, 3D display technology is The application scheme on the LED display has become a hot spot and direction in recent years. At this year's Guangzhou International led exhibition we also see a lot of vendors led display in doing the appropriate technical innovations spare no spare capacity for 3DLED display recount in research and development 3DLED display.It is understood that Lingxing Rain has launched a set of 3D solutions for 3D LED display. The general manager of Lingxing Yu said that “The Star Rain 3D solution supports polarized 3D and naked eye 3D technology, which is the best and most mature in the industry. LED display 3D solution. In the future cinema, it will replace the movie screen that appears in the theater, and it has the advantage of high brightness and gray level of 18 bits.†At the same time, the advantages of the Lingxing 3D solution compared with the traditional projection projection prominent. Zhou Da said that "the 3D film and television broadcasted by the Lingxing Rain Control System will not defocus, no loss of convergence, no 3D film syndrome, high brightness, high contrast, etc., which exceeds the stereoscopic cinema IMAX in 17 major indicators, but in the near future In the future, IMAX will be replaced. It is reported that the current 3D system of Lingxing Rain has already been put into use in theaters and places such as the Hong Kong Kwai Tsing Theatre and the Milan Expo.
At present, 3D cinema adopts 3D, which is a kind of polarized 3D, which is made by the visual difference caused by light. At present, most of the finished products of naked-eye 3D display developed by led display manufacturers have defects of viewing angle limitation. Wang Peng, deputy general manager of Shanghai Sansi, also said that many companies are now developing and producing naked-eye 3D LED displays. In this process, many problems will be reflected. The most important technical point lies in the design of “multi-viewâ€. Allows the viewer to see the 3D effect no matter where they stand. “Now, it’s good to do one, two, four, and eight viewpoints, but it’s going to be difficult to do dozens of viewpoints.â€
In order to make up for some technical limitations of naked-eye 3D technology, some LED display manufacturers have gradually turned to active 3D technology in the continuous research and development process. Active 3D technology can also be called shutter type 3D technology, which is achieved by greatly increasing the refresh rate of the picture. It divides the image into two groups according to the frame, forming the left and right corresponding pictures, and continuously interleaving to generate images. The 3D image is seen by the synchronous on/off operation of the lenses of the shutter glasses. Unlike the polarized 3D, he can restore the original resolution of the picture, and can easily enjoy full HD 3D images, breaking through the limitations of the original naked-eye D "multi-view" station.
In addition, Easystar also introduced direct 3D this year. By adding a 3D conversion box to an ordinary display screen and turning ordinary 2D into 3D, it greatly saves costs and facilitates customer operations. Generally, only products that support 3D playback are different. This product can choose to play 2D or 3D according to your preference.
Of course, we do not rule out that the LED display under the new 3D technology still has its defects, but we can imagine that with the development of 3D technology and the increasing resolution of small-pitch led display , I believe it will be soon. The future 3D HD LED display will bring a new visual experience to the audience.
3D technology will impact the traditional display market, LED display manufacturers need to seek diversification
The application of 3D display technology in LED display has greatly changed people's visual experience, and also has a huge impact on the LED display market. As a manufacturer of LED display screens, in the situation of 2D display to 3D display technology innovation, Will face new challenges and shocks.
The application of 3D technology will effectively evade industry homogenization competition. The application of 3D technology to LED displays is a brand new field, and only a few companies in the mainland are developing. It can be said that the use of 3D technology on LED display screens will add additional added value to LED display products. In the homogenization competition, avoiding the competition clustering point, it can win in the homogenization competition. Market initiative. In addition, because the use of LED in 3D technology is a new thing, there is no problem that is dominated by some large production areas or large enterprises in the mainland, and it takes the lead in this new field.
Second, led display manufacturers need to seek diversification. Affected by 3D display technology, the first to bear the brunt of the traditional 2D display technology screen suppliers, as the market such as participating in the show is more inclined to content differentiation, image personalization needs, and more or less turned to 3D technology It is bound to affect the traditional business of traditional 2D suppliers. Therefore, in the face of such a positive and strong attack, most screen suppliers need to change the direction of the product line strategy, face challenges in a diversified and differentiated form, cooperate with 3D LED display manufacturers and institutions, and expand product lines. Stay competitive and keep pace with the times.
Of course, it is inevitable to force the price of traditional 2D LED splicing screens to drop. Faced with the debut of 3D technology, the living space of traditional 2D LED splicing screen suppliers will be further compressed. At the same time, in order to maintain sales, each merchant inevitably needs to reduce the price of 2DLED display to continue its competitiveness. But this is not bad, which will prompt some LED display manufacturers to focus on market segments, which will help further segmentation and expansion of the entire industry.
brightness
LCD is a substance between solid and liquid. It can't emit light by itself, so it needs additional light source. Therefore, the number of lamps is related to the brightness of the Liquid Crystal Display. The earliest liquid crystal displays had only two upper and lower tubes, the lowest of the popular type was four lamps, and the high-end one was six lamps. The four-lamp design is divided into three types of placement: one is that there is a lamp on each of the four sides, but the disadvantage is that there will be dark shadows in the middle. The solution is to arrange the four lamps from top to bottom. The last one is the "U"-shaped placement form, which is actually two lamp tubes produced by two lamps in disguise. The six-lamp design actually uses three lamps. The manufacturer bends all three lamps into a "U" shape, and then places them in parallel to achieve the effect of six lamps.
Tip: Brightness is also a more important indicator. The brighter the LCD, the brighter the LCD, it will stand out from a row of LCD walls. The highlight technology we often see in CRT (ViewSonic is called highlight, Philips is called display Bright, BenQ is called Rui Cai) is to increase the current of the shadow mask tube to bombard the phosphor to produce a brighter effect. Such a technology is generally traded at the expense of image quality and the life of the display. All use this The products of this kind of technology are all bright in the default state, you always have to press a button to implement, press 3X bright to play the game; press again to turn to 5X bright to watch the video disc, a closer look is blurred, you need to watch The text has to be honestly returned to the normal text mode. This design actually prevents you from frequently highlighting. The principle of LCD display brightness is different from that of CRT. They are realized by the brightness of the backlight tube behind the panel. Therefore, the lamp has to be designed more so that the light will be uniform. In the early days when selling LCDs, it was a great thing to tell others that there were three LCDs. But at that time, Chi Mei CRV came up with a six-lamp technology. In fact, the three tubes were bent into a "U" shape. The so-called six; such a six-lamp design, plus the strong luminescence of the lamp itself, the panel is very bright, such a representative work is represented by VA712 in ViewSonic; but all bright panels will have a fatal injury , The screen will leak light, this term is rarely mentioned by ordinary people, the editor personally thinks it is very important, light leakage means that under a completely black screen, the liquid crystal is not black, but whitish and gray. Therefore, a good LCD should not emphasize brightness blindly, but more emphasis on contrast. ViewSonic's VP and VG series are products that do not emphasize brightness but contrast!
