At present, full-color LED display in order to achieve high-definition display, generally require two basic premises, one is the video itself must be high-definition, and second, the LED display you have to support high-definition display can be achieved.
With the development of society and the advancement of science, people are demanding higher and higher display quality of LED display screens. HD and ultra-high definition displays have gradually become the mainstream of the market. The shocking effect brought by high-definition video is very strong. The displayed content is more attractive than traditional video images, and can better satisfy people's pursuit of high-quality audio-visual. So in addition to the two basic premise mentioned earlier, how to make full-color LED display to become more HD it?

First, improve the contrast of full-color LED display: contrast is one of the key factors that affect the visual effects, in general, the higher the contrast, the more vivid the image, vivid colors. High contrast for the image clarity, detail performance, the level of grayscale performance are of great help. In some large black and white contrast text, video display, high contrast full color LED display in black and white contrast, clarity, completeness and other advantages. Contrast for dynamic video display to a greater impact, due to the dynamic image of the light and shade conversion faster, higher contrast, the human eye easier to distinguish the image conversion process. Full-color LED display contrast is mainly to improve the brightness of the LED display and reduce the surface reflectance of the display, but the brightness is not the higher the better, too high, but will be counterproductive, not only will affect the life of the LED display, Light pollution will also cause adverse effects on the environment and the population. Full-color LED display LED panels and LED tubes for special processing, can reduce the LED panel reflectivity, but also can improve the contrast of full-color LED display.

Second, improve the full-color LED display grayscale: LED display grayscale refers to the single-color brightness from the darkest to the brightest, can distinguish between the brightness levels, full-color LED display grayscale The higher the color, the richer, the more beautiful colors; the other hand, the display color is single, change is simple. Grayscale to improve, can greatly enhance the color depth, making the image color display level geometry increased. Now a lot of LED display manufacturers can do the gray scale of the display 14bit ~ 16bit, so that the image level resolution details and display more subtle and vivid, colorful.
Third, reduce the full-color LED display point spacing: Narrow the full-color LED display point spacing, can improve the clarity of the display screen, because the smaller the spacing between the dots, the LED display unit area pixel density is higher , To show more details, the more detailed picture display lifelike.

Fourth, the combination of LED display and video processor: LED video processor can use advanced algorithms to poor signal quality image modification, the implementation of de-interlacing, edge sharpening, motion compensation and a series of processing to enhance the image display details , Improve the picture display quality. The use of video processor image scaling algorithm to ensure that the video image scaling processing to maximize the image clarity and gray level; In addition, the video processor also needs a wealth of image adjustment options and adjust the effect of the image Brightness, contrast, grayscale processing, to ensure that the LED display output soft and clear picture.
