To achieve high-definition display must have four factors: first, the video source requires full HD; Second, the LED display is required to support full HD; Three is to reduce the point spacing of the LED display; Fourth, the LED display is combined with the video processor. At present, LED full-color display is also moving towards higher definition display.

In some text and video displays with large black-and-white contrast, high-contrast full-color LED displays have advantages in black-and-white contrast, clarity, integrity and so on. The effect of contrast on dynamic video display is greater, because the light and dark conversion in dynamic images is faster, the higher the contrast, the easier it is for the human eye to distinguish such a conversion process. In fact, the contrast improvement of the LED full color screen is mainly to improve the brightness of the LED display and reduce the reflectivity of the screen surface, however, the brightness is not the higher the better, too high, but will backfire, not only affect the life of the led display, but also cause light pollution. Light pollution has become a hot topic now, and too much brightness will have an impact on the environment and people. LED panel and LED light tube for special processing, can reduce the reflectivity of the LED panel, but also can improve the contrast of the 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 the LED full color screen. The higher the gray level of the 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 increase of gray level can greatly improve the color depth, so that the display level of the image color is increased geometrically. The LED gray level control level is 14bit~16bit, making the image level resolution details and display effect of high-end display products have reached the world's advanced level. With the development of hardware technology, LED gray level will continue to develop to higher control accuracy.

Narrowing the point spacing of the LED full-color display can improve its clarity, and the smaller the point spacing of the full-color LED display, the more delicate the screen display. However, this point, there must be mature technology as the core support, its investment cost is relatively large, the price of the produced full-color LED display is also high, but fortunately now the market is also moving toward the development of small-pitch led display.

LED video processor can use advanced algorithms to modify the signal of poor image quality, perform a series of processing such as deinterlacing, edge sharpening, motion compensation, etc., to enhance the details of the image and improve the picture quality. The video processor image scaling algorithm is used to ensure that the sharpness and gray level of the video image are maintained to the maximum extent after the video image scaling processing. In addition, the video processor is also required to have a wealth of image adjustment options and adjustment effects, image brightness, contrast, gray level processing, to ensure that the LED screen output soft and clear picture.
