Since its birth, LED displays have received extensive attention. With the continuous improvement of installation technology in recent years, it has been recognized and applied in various industrial fields. LED display production and maintenance also requires professional knowledge, how to achieve high-definition display? To achieve high-definition display must have four factors: First, the film source requires full HD; Second, the display requirements can support full HD; Third, reduce the LED display The point spacing of the screen; four is the combination of LED display and video processor. At present, LED full-color display is also moving towards higher clarity.
Enhancing the contrast of the full-color LED display is one of the key factors that affect 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 LED full-color screen is mainly to improve the brightness of full-color LED display screen and reduce the surface reflectivity of the screen body, but the brightness is not the higher the better, too high, but will be counterproductive, not only will affect the LED display Life will 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.
To increase the full-color LED display grayscale grayscale level refers to the full-color LED full-screen single-color brightness can be distinguished from the darkest to the brightest light level, the higher the gray level of Yunhai glory full-color LED display, The richer the color, the brighter the color; on the contrary, the display color is simple and the change is simple. 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.
Reducing the dot pitch of full-color LED displays By reducing the dot pitch of full-color LED displays, the sharpness of the full-color LED display can be improved. 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 by the price is also high, but fortunately now the market is also moving towards the development of small-pitch LED display.
LED full-color display and video processor combined LED video processor can use advanced algorithms to modify the signal of poor image quality, perform deinterlacing, edge sharpening, motion compensation and a series of processing, enhance the details of the image, Improve 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 rich image adjustment options and adjustment effects to process the image brightness, contrast, and gray scale so as to ensure that the screen output is soft and clear.
