How to make the LED display more HD

As society develops faster and faster, LED display screens can be seen everywhere. As the main carriers of advertising and information broadcasting, led display follows the trend of the times in contemporary era. High-definition video often gives people a more stunning visual experience, and the displayed content will be more realistic. How to make the LED display more HD?

To achieve high-definition display must have four factors, first the source requires full HD, the second is the display can support full HD, the third is to reduce the LED display pitch, the fourth is using LED display and video processor. Full-color LED displays are 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. 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 improvement of full-color LED display screens is mainly to increase the brightness of full-color LED display screens and reduce the surface reflectivity of the screens. However, the brightness is not as high as possible. Too high 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. 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 a full-color LED display screen, which can be distinguished from the darkest to the brightest. The higher the gray level of a 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. 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.

Third, reduce the full-color LED display pitch

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 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 as much as possible. 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.
