Want a higher definition led video advertising wall display?

1、 To improve the contrast of full-color LED display, contrast is one of the key factors affecting the visual effect. Generally speaking, the higher the contrast is, the clearer the image is, the more vivid the color is. High contrast for image clarity, detail performance, gray level
1、 To improve the contrast of full-color LED display, contrast is one of the key factors affecting the visual effect. Generally speaking, the higher the contrast is, the clearer the image is, the more vivid the color is. High contrast is very helpful to the definition, detail and gray level of the image. The contrast enhancement of full-color LED display is mainly to improve the brightness of the LED display and reduce the surface reflectance of the display. However, the brightness is not the higher the better. If it is too high, it will backfire. It will not only affect the life of the LED display, but also cause light pollution and have adverse effects on the environment and people. The LED panel and LED light-emitting tube of full-color LED display screen are processed by special technology, which can reduce the reflectivity of LED panel and improve the contrast of full-color LED display screen.
2、 Improve the gray level of LED full-color display screen. Gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness of LED full-color display screen. The higher the gray level of full-color LED display screen is, the richer the color is, and the brighter the color is; On the contrary, the display color is single and the change is simple. The improvement of gray level can greatly enhance the color depth, and make the display level of image color increase geometrically.

3、 Reducing the point spacing of LED full-color display and reducing the point spacing of LED full-color display can improve its clarity. The smaller the point spacing of full-color LED display is, the higher the pixel density of LED display unit area is, the more details can be displayed, and the more delicate the picture display is.
4、 With the combination of LED full-color display and video processor, LED video processor can use advanced algorithms to modify the signal with poor image quality, perform a series of processing, such as de interlacing, edge sharpening, motion compensation and so on, enhance the details of the image and improve the image quality. The video processor image scaling algorithm is used to ensure that the clarity and gray level of the image are maintained to the greatest extent after the video image is scaled. In addition, the video processor is also required to have a wealth of image adjustment options and effects to process the brightness, contrast and gray of the image, so as to ensure the soft and clear screen output.
