Since the first half of this year, several led display companies have launched new products and technological innovations through online live broadcasting. Many new products have appeared one after another, refreshing the audience’s new understanding of LED display large screen. In these live broadcast conferences, indoor large commercial LED screen frequency has become the focus of screen companies.
The Rise of Indoor LED Big Display
In the early days, the HD LED display market has been dominated by DLP display and LCD display. The most important factor is that the picture composition of LED display is composed of LEDs, no matter how small the pitch between the lamps is, it can’t be compared with LCD and DLP. LCD uses the photoelectric effect of liquid crystal molecules to change the transmittance or reflectivity of liquid crystal cells to achieve picture display, while DLP uses the core DMD display chip for digital processing, and the light passes through the color wheel to complete the display on the chip. Different display principles lead to different picture effects. For LED displays, how to avoid obvious pixel color patches and granularity in near-eye mode becomes the main point to tackle.
With the further reduction of pixel pitch and the upgrading of display packaging technology, LED displays have gradually conquered the indoor HD display market in recent years. The most typical representatives are conference scenes and the application of LED display in the field of optoelectronics. Meeting scenes are near-eye display scenes, with the pixel pitch records of LED displays refreshing. Small pixel pitch LED display is sufficient to better meet the resolution requirements of large indoor LED screens, and can display high-definition pictures in DVD, SD, HD, SXGA+ formats. The data shows that video wall applications in the business conference industry accounted for about 15% of the total video wall market share in 2014, which is one of the main application areas of small pixel pitch LED display. In some important meeting occasions, it is not only the live audience who is watching the big screen, but also the ‘off-site guests’ who watch on TV after being recorded by the camcorder. It is tested by the ‘two eyes’ of the live audience and the TV audience. That is to say, in the dual use environment of live broadcasting and live Camcorder broadcasting, small pixel pitch LED display should meet many high-standard display requirements such as low brightness and high gray, color restoration, high refresh, system stability, and so on. Also in the field of broadcasting and television, large LED screen display technology is also used in professional broadcasting halls in the field of broadcasting and television. In the programs that need to take the host as the core such as news, variety art, it is necessary to display the necessary graphic information or video with the help of the large screen behind the host to meet the needs of the program. In the field of broadcasting and television, the requirements for broadcasting effect are relatively high, so there are strict checks on all parameters of the display, such as refresh rate to achieve certain requirements, so that when the video is taken by the camcorder, the difference between the refresh rates will not cause ‘black light band’ and other issues. For example, since the host is always in front of the display, studios need the display to be able to restore good color and display effect at lower brightness to avoid affecting the host effect due to too high brightness of the display. Strict picture requirements make the LED display have new technological advantages such as fast response and no shadow, high refresh rate and no flicker, high gray level with adjustable brightness, wide color gamut and wide angle, intelligent transmission and control systems. With these advantages, the role of LED display in the field of radio and television can no longer be replaced, becoming the center protagonist of professional studio display devices.
Continuous power Game from Commercial Display to Consumer-grade Large Screen Market
From the new products released by screen companies, the indoor large LED screen market has been the focus of many screen companies.
From the recent launch of new products in several major announcements, it can be seen that indoor scene solutions have become the focus of attention of screen companies, traditional rental LED screen market, immersive scene applications, the large commercial LED display, or the emerging market developed with the continuous upgrade of technology, such as home theater, the application of LED display in indoor display scene is more and more widespread, and is continuously penetrating.
Epilogue
For the continuous penetration of LED display in the large indoor LED screen market, the factors behind it are not only the maturity of display technology, cost reduction, protection upgrade, display effect upgrade, etc., but also the maturity of the market for the diversified application market of LED display products. Consumers are getting closer to LED display products and familiar with the indoor LED display products appearing in a variety of life scenes, such as shops, office buildings, exhibitions, conference rooms, or emerging cinemas, immersion pavilions. Even TV products are replaced by LED displays. With the further upgrade of LED display technology, the consumer market is no longer an area where LED displays cannot reach.
