If you want a clearer LED display, you can easily grasp the four factors.

LED display has received a lot of attention since its birth. With the continuous improvement of installation technology in recent years, it has been approved by 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 dot spacing; Fourth, LED display and video processor combination. At present, LED full-color display is also moving towards higher clarity.

1, improve the contrast of LED full-color 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 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.

2, increase the full-color LED display grayscale

Gray scale refers to the brightness level of the single-color LED full-color screen from the darkest to the brightest. The higher the gray level, the richer the color, the brighter 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. LED gray scale control level is 14bit~16bit, which makes the high-level display product's 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.

3, reduce the LED full color display point spacing

Reducing the dot pitch of LED full-color display can greatly improve its sharpness. The smaller the dot pitch of 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 the market is also moving towards the development of small-pitch LED display.

4, LED full color 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 processing algorithm is used to ensure that the video image is scaled to maintain the sharpness and gray level of the image to a large 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.
