How to improve the definition of full-color LED display?

Feb 22,2022 254 views

As the main carrier of advertising and information broadcasting, full-color LED screen keeps up with the trend of the contemporary era. High-definition video often brings more shocking visual experiences to people, and the displayed content will be more realistic. There must be two factors to realize HD display. One is that the movie source needs full HD, and the other is that the display needs to support full HD. In fact, the full-color LED display is also moving towards higher definition display. Then, how can we make the full-color LED display clearer? Next, we will make a rough analysis.

Improve the contrast of full-color 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 the color. High contrast is very helpful to the clarity, detail performance and gray level performance of the image. In some texts with large black-and-white contrast, high contrast full-color LED display has advantages in black-and-white contrast, clarity, integrity and so on. Contrast has a greater impact on the dynamic video display effect. Because the light and shade conversion in dynamic images is relatively fast, the higher the contrast, the easier it is for people's eyes to distinguish such conversion process. In fact, improving the contrast of full-color LED display is mainly to improve the brightness of full-color LED display and reduce the reflectivity of screen surface. However, the higher the brightness, the better, it will backfire. Light pollution has become a hot topic. High brightness will have an impact on the environment and people. The special processing of full-color LED display panel and LED light-emitting tube can reduce the reflectivity of LED panel and improve the contrast of full-color LED display.

Improve the gray level of full-color LED display

Gray level refers to the brightness level from dark to bright, which can be distinguished between the monochrome brightness of full-color LED display screen. The higher the gray level of full-color LED display, the richer the color and the more gorgeous the color; On the contrary, the display color is single and the change is simple. The improvement of gray level can greatly improve the color depth and increase the display level of image color in geometric numbers. The gray control level of LED is 14bit ~ 16bit, which makes the image level, detail and display effect of high-end display products reach the world advanced level. With the development of hardware technology, led gray level will continue to develop to higher control accuracy.

Reduce the pixel of full-color LED display

Reducing the pixel of full-color LED displays can improve their clarity. The smaller the dot spacing of full-color LED display, the more exquisite the screen display will be. However, there must be mature technology as the core support. Its investment cost is relatively large, and the price of full-color LED video wall is also very high. Fortunately, the market is also developing towards small spacing LED display.
