Human screen interaction is an important direction of LED display

Full color LED display screen “in front of the screen and behind the screen” cooperate with each other.

Only with the assistance and cooperation of the supporting equipment in front of and behind the screen, can the indoor screen and small space display effect be more perfect.

Yang Lichang said: “with the LED display screen moving from outdoor to indoor, compared with the outdoor large LED screen, the audience’s identification rate of indoor LED screen is improved, and the requirements for display color and display effect are also higher. To meet these higher requirements, we must rely on the supporting equipment behind the scenes – lamp beads, driving IC, video processor, control system, enz., to do the corresponding cooperation.”

“Secondly, the rise of small spacing leads to direct competition with traditional indoor splicing large screens such as LCD and DLP rear projection. Echter, at present, small spacing is at a disadvantage in terms of technology – point spacing (LCD LCD dot spacing can achieve p0.6) or cost. Although small spacing seamless splicing, hoog contrast, wide color gamut display, energy saving and other aspects can occupy one However, in the future, small space LED display must be more excellent if we want to continue to occupy the market share of indoor large screen splicing with LCD LCD and DLP rear projection, and these all need the assistance and cooperation of supporting equipment, so as to achieve a more perfect display effect of indoor LED display screen and small space LED display screen. ”

hoog contrast, high gray and high refresh rate are the direction of future efforts.
full-color LED display is a hot topic in the current industry. Why small spacing LED display is sought after by the industry and consumers is obviously because the display effect of small spacing is better than that of traditional indoor splicing large screen, such as LCD. In order to achieve the display effect of “low brightness, high gray and high brush” van small pitch LED display screen, the driving IC undoubtedly plays the most important role.

in this regard, Yang Lichang told reporters: “compared with the lamp beads which account for 70% of the total cost of the LED display screen, the cost of driving IC is somewhat insignificant, but its role is decisive: hoge verversingssnelheid, hoog contrast, high gray and other display effects must rely on the cooperation of the driving IC to complete.” At the early stage of the market entry of

small spacing LED display screen, the topic most talked about was how to solve the seven major problems of small spacing LED display screen: Ghost, first line dark line, low gray color deviation, low gray uneven, gradient dark line, high contrast interference, and elimination of cross phenomenon caused by LED open circuit. With the rapid progress of technology in recent years, these problems have been solved perfectly with the technical cooperation and cooperation of the manufacturers of driving IC and control system. As a driver IC manufacturer, our next task is to further improve the contrast, gray level and refresh rate of LED display, and we should not sacrifice its gray level while improving the contrast. This is a challenge for us, and we need to work together with manufacturers such as lamp beads and control systems. ” Yang added.
