There are two basic premise for full-color LED display to achieve high-definition display. One is that the video source must be high-definition, and the other is that your full-color LED display must support high-definition display.
With the development of society, people have higher and higher requirements for the display of full-color LED display screens, and high-definition and ultra-high-definition displays have gradually become the mainstream of the market. The shocking effect of high-definition video images is very strong, and the displayed content is more attractive than traditional video images, and it can better satisfy people's pursuit of high-quality audio-visual. So, besides the two basic premise mentioned above, how can we make the full-color LED display more HD? The following full-color LED display manufacturers expand the photoelectric to give you analysis and analysis.
First, improve the contrast of the full color LED display:
Contrast is one of the key factors affecting visual effects. Generally speaking, the higher the contrast, the clearer and vivid the image, and the more vivid the color. High contrast is very helpful for image sharpness, detail performance, and gray level performance. In some text and video displays with large contrasts in black and white, high-contrast full-color LED displays have advantages in black-and-white contrast, sharpness, and integrity. Contrast has a greater impact on dynamic video display. Because the light and dark transitions in moving images are faster, the higher the contrast, the easier it is for the human eye to distinguish the image transition process. The contrast improvement of the full-color LED display is mainly to improve the brightness of the LED display and reduce the reflectivity of the display surface. However, the brightness is not as high as possible, too high, but it will be counterproductive, not only affecting the full-color LED display. Life expectancy will also cause light pollution to adversely affect the environment and people. The full-color LED display LED panel and LED lighting tube are specially processed to reduce the reflectivity of the LED panel and also improve the contrast of the full-color LED display.
Second, improve the gray level of full-color LED display:
The gray level of the LED display refers to the brightness level from the darkest to the brightest in the single primary color brightness. The higher the gray level of the full color LED display, the richer the color, the more vivid the color; The display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, and the display level of the image color increases geometrically. Now many full-color LED display manufacturers can make the gray level of the display 14bit~16bit, which makes the image layer distinguish details and display effects more delicate and vivid.
Third, reduce the dot spacing of the full color LED display:
Reducing the dot pitch of the full-color LED display can improve the clarity of the display screen, because the smaller the dot pitch, the higher the pixel density per unit area of ??the full-color LED display, the more details that can be displayed, the screen display The more delicate and realistic it is.
Fourth, the combination of full color LED display and video processor:
The LED video processor can use advanced algorithms to modify the signal with poor image quality, perform deinterlacing, edge sharpening, motion compensation and other series of processing to enhance image display details and improve picture display quality. The video processor image scaling processing algorithm is used to ensure that the video image is scaled and processed to maximize the sharpness and gray level of the image; in addition, the video processor has rich image adjustment options and adjustment effects on the image. Brightness, contrast, and grayscale are processed to ensure a soft and clear picture of the full-color LED display.
