With the rise of small pitches, the importance of driver ICs has become more prominent, and it has attracted more and more attention. How should driver ICs be adjusted to adapt to new roles? Today, the function of LED display screens is limited to static, monotonous, and repeated commercial advertisements. How should we think and position for the future development of LED displays, especially small pitches?
The true meaning of "Behind the scenes"
In front of the screen - the perfect display picture presented by the LED display, behind the screen - the efforts of the LED display supporting manufacturers behind the scenes. Obviously, without the mutual cooperation of these supporting equipment behind the scenes, it is impractical to realize the perfect display picture of the LED display.
As LED displays move from outdoors to indoors, compared with outdoor large screens, the audience's recognition rate of indoor screens has increased, and the requirements for display colors and display effects are also higher. To meet these higher requirements, we must Rely on the supporting equipment behind the scenes - lamp beads, driver ICs, video processors, control systems, etc. to cooperate accordingly.
Secondly, the rise of small spacing has triggered direct competition with traditional indoor splicing large screens such as LCD liquid crystal and DLP rear projection. , or cost, small pitches are at a disadvantage, although small pitch seamless splicing, high contrast, wide color gamut display, energy saving and other aspects can occupy certain advantages, but in the future, small pitches will continue to compete with LCD liquid crystals and DLP. In order to seize the share of the indoor large-screen splicing market, the small pitch must be better, and the assistance and cooperation of supporting equipment are indispensable for these. Therefore, we set the theme of this meeting as "behind the screen", to discuss how to continue to improve the performance of these supporting equipment behind the LED display screen, and how these related equipment cooperate with each other to realize indoor screens, small screens, etc. The spacing is more perfect for the display effect.
High contrast, high grayscale and high refresh rate are the direction of future efforts
Small spacing is a hot topic in the current industry. Why small spacing is sought after by the industry and favored by consumers is obviously because the display effect of small spacing is more excellent, extreme and perfect than traditional indoor splicing large screens, such as LCD liquid crystal. In order to achieve the display effect of "low brightness, high gray and high brush" with small pitch, the driver IC undoubtedly plays the most critical role in it.
Compared with the lamp beads that account for 70% of the total cost of the entire LED display, the cost of the driver IC is insignificant, but its role is very important: high refresh rate, high contrast, high grayscale and other display effects must be It depends on the cooperation of the driver IC to complete.
In the early days of small pitches entering the market, the most talked about topic is how to solve the seven major problems of small pitches - ghosting, dark lines in the first line, low gray color cast, low gray unevenness, gradient dark lines, high contrast interference, and elimination of LED open circuits resulting in the phenomenon of the cross. After several years of rapid technological progress, these problems have been perfectly solved with the technical cooperation and joint efforts of manufacturers such as driver ICs and control systems.
LED display needs to add more interactive elements.
For LED display companies, small pitch is a brand new battlefield and a brand new opportunity. Small pitch will directly impact LCD liquid crystals. The prospect is very good in the next two to three years. At present, the most important problem that needs to be solved in small spacing is how to reduce the cost, especially how to reduce the cost of lamp beads. Therefore, the manufacturing process of lamp beads must be greatly improved and upgraded. For driver ICs, the future will continue to develop in the direction of high integration and high integration, and how to help customers reduce the overall cost of display screens is of greater significance. This is also a problem that we need to think about and improve next. All of these can only be achieved by relying on technological breakthroughs and innovations, even revolutionary technological breakthroughs. Otherwise, the small pitch will hardly shake the position of LCD liquid crystal in the indoor large-screen splicing market.
Of course, the LED display, especially the small pitch with such excellent display effect, is obviously not enough to just blindly improve its display effect. We need to continue to explore how to diversify the functions and applications of the display screen and maximize its value, and human-screen interaction is an extremely important direction for the value enhancement of LED display screens in the future. We should not only position the LED display as a static advertising carrier, we should think about how to achieve a good interaction between the audience and the display, maximize the effectiveness of the advertisement, and maximize the output of the advertisement. Maximize, that will also indirectly increase the value of LED display and broaden the application field of LED display.
