To achieve high-definition display must have four factors, one source requires full HD, the second is the display requirements to support full HD, the third is to reduce the LED display dot spacing, the fourth is led display and video processor combination. Full-color led display is actually moving towards higher clarity.
First, improve the contrast of full-color LED display
Contrast is one of the key factors affecting the visual effect. In general, the higher the contrast, the clearer the image is and the brighter the color is. High contrast is very helpful for image clarity, detail performance, and grayscale performance. In some black and white contrast text, video display, high-contrast full-color LED display in black and white contrast, clarity, integrity and other aspects have advantages. Contrast has more influence on the dynamic video display effect. Because the light and shade conversion in the dynamic image is faster, the higher the contrast, the easier the human eye can distinguish the conversion process.
In fact, the contrast of full-color LED display screen is mainly to improve the brightness of full-color LED display screen and reduce the surface reflectivity of the screen. However, the brightness is not the higher the better, too high, but will be counterproductive, not only will affect the led display The life of the screen can also cause light pollution. Light pollution has become a hot topic now. Excessive brightness will affect the environment and people. Full-color LED display The LED panel and LED light-emitting tube undergo special processing to reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display.
Second, increase the gray level of full-color LED display
Gray scale refers to the brightness level of the single primary color brightness of the full-color LED display screen that can be distinguished from the darkest to the brightest. The higher the gray level of the full-color LED display, the richer the color, the more colorful the color; , display a single color, simple changes. The increase in gray level can greatly increase the color depth, so that the display level of the image color increases geometrically. The LED gray scale control level is 14bit~16bit, which makes the high-level display products' image level resolution detail and display effect reach the world advanced level. With the development of hardware technology, LED gray scale will continue to develop higher control accuracy.
Third, reduce the full-color LED display point spacing
Reducing the dot pitch of a full-color LED display can improve its sharpness. The smaller the dot pitch of a full-color LED display, the finer the screen display. However, this must be mature technology as the core support, the input cost is relatively large, the full color LED display produced into the price is also high, but fortunately now the market is also moving towards a small pitch led display development.
Fourth, led display and video processor combination
The LED video processor can use advanced algorithms to modify the signal with poor image quality and 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 video image is scaled to maintain the sharpness and gray level of the image to the greatest extent. In addition, the video processor is also required to have a variety of image adjustment options and adjustment effects to process the image brightness, contrast, and grayscale to ensure that the screen output is soft and clear.
