1. 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 and more vivid the image, and the more vivid the color. High contrast is very helpful for image sharpness, detail performance, and gray level performance. In some text and video displays with large contrasts in black and white, high-contrast full-color LED displays have advantages in black-and-white contrast, sharpness, and integrity. Contrast has a greater impact on dynamic video display. Because the light and dark transitions in moving images are faster, the higher the contrast, the easier it is for the human eye to distinguish the image transition process. The contrast improvement of the full-color LED display is mainly to improve the brightness of the LED display and reduce the reflectivity of the display surface. However, the brightness is not as high as possible, too high, but it will be counterproductive, which will not only affect the life of the LED display. It will also cause light pollution to adversely affect the environment and people. The full-color LED display LED panel and LED lighting tube are specially processed to reduce the reflectivity of the LED panel and also improve the contrast of the full-color LED display.


2, improve the gray level of full color LED display


The gray level of the LED display refers to the brightness level from the darkest to the brightest in the single primary color brightness. The higher the gray level of the full color LED display, the richer the color, the more vivid the color; The display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, so that the display level of the image color increases geometrically. Now many LED display manufacturers can achieve the gray level of the display to 14bit ~ 16bit, so that the image level to distinguish details and display effects more delicate and realistic, colorful.


3, reduce the dot pitch of the full color LED display


Reducing the dot pitch of the full-color LED display can improve the sharpness of the display screen. Because the dot pitch is smaller, the pixel density per unit area of the LED display is higher, and the details can be displayed more. Delicate and realistic.


4, LED display and video processor combined


LED video processor can use advanced algorithms to modify the signal with poor image quality, perform deinterlacing, edge sharpening, motion compensation and other series of processing to enhance image display details and improve picture display quality. The video processor image scaling processing algorithm is used to ensure that the video image is scaled and processed to maximize the sharpness and gray level of the image; in addition, the video processor has rich image adjustment options and adjustment effects on the image. Brightness, contrast, and grayscale are processed to ensure a soft and clear view of the LED display.
