LED display is the main carrier of advertising and information playback nowadays, and high definition video can bring people a more shocking visual experience, and the displayed content will be more realistic. To achieve high-definition display, there must be two factors, one is that the film source requires full HD, and the other is that LED display needs to support full HD. The full-color LED display is actually moving towards a higher-definition display, so how can we make full color LED display clearer?
1, Improve the gray scale of full color LED display
The gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness of full color LED display. The higher the gray level of LED display, the richer the color and the brighter the color, the display color is single and the change is simple. The improvement of the gray level can greatly improve the color depth, so that the display level of the image color increases geometrically. The LED grayscale control level is 14bit~20bit, which makes the image level resolution details and display effects of high-end display products reach the world's advanced level. With the development of hardware technology, LED gray scale will continue to develop to higher control precision.
2, Improve the contrast of LED display
Contrast is one of the key factors affecting visual effects. Generally speaking, the higher the contrast, the clearer the image and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and grayscale performance. In some video displays with large black and white contrast, the high contrast RGB LED display has advantages in black and white contrast, clarity, integrity, etc. Contrast has a greater impact on the display effect of dynamic video. Because the light and dark transition in dynamic images is relatively fast, the higher the contrast, the easier it is for human eyes to distinguish such a transition process. In fact, the improvement of the contrast ratio of the full color LED display is mainly to improve the brightness of full color LED display and reduce the surface reflectivity of the screen. However, the brightness is not as high as possible, too high, it will be counterproductive, and light pollution has become a hot spot now. On the topic of discussion, too high brightness will have an impact on the environment and people. The full color LED display LED light-emitting tube undergoes special processing, which can reduce the reflectivity of the LED panel and improve the contrast of the full color LED display.
3, Reduce the pixel pitch of LED display
Reducing the pixel pitch of the full color LED display can greatly improve its clarity. The smaller the pixel pitch of LED display, the more delicate LED screen display. However, Its input cost is relatively large, and the price of full color LED display produced is also high. Now the market is also developing towards small pitch LED displays.
