There are two basic prerequisites for achieving high-definition display on a full-color LED display. One is that the video source must be high-definition, and the other is that your LED display must support high-definition display. So in addition to the two basic premises mentioned earlier, how to make the full-color LED display screen more high-definition? Let me give you the analysis below：
1. Improve the contrast of full-color LED display
Contrast is one of the key factors that affects visual effects. Generally speaking, the higher the contrast, the clearer and more realistic the image, and the more vivid and colorful the color. High contrast is very helpful for image clarity, detail expression, and grayscale expression. In some text and video displays with large black and white contrast, high-contrast full-color LED displays have advantages in black and white contrast, clarity, and completeness. Contrast has a greater impact on dynamic video display effects. Since the light and dark transitions in dynamic images are relatively fast, the higher the contrast, the easier it is for the human eye to distinguish the image conversion process. The contrast improvement of the full-color LED display is mainly to increase the brightness of the LED display and reduce the surface reflectivity of the display. However, the higher the brightness, the better. If it is too high, it will be counterproductive, which will not only affect the life of the LED display. It will also cause light pollution to have adverse effects on 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. Improve the gray level of full-color LED display
The gray level of the LED display refers to the brightness level that can be distinguished from the darkest to the brightest in a single primary color. The higher the gray level of the full-color LED display, the richer the color and the more gorgeous the color; vice versa. , the display color is single and the change is simple. The improvement of gray scale can greatly enhance the color depth, causing the display levels of image colors to increase geometrically. Nowadays, many LED display manufacturers can adjust the gray scale of the display to 14bit~16bit, making the image level resolution details and the display effect more delicate, realistic and colorful.
3. Reduce the dot pitch of the full-color LED display
Reducing the dot spacing of the full-color LED display can greatly improve the clarity of the display screen, because the smaller the dot spacing, the higher the pixel density per unit area of the LED display, the more details it can display, and the clearer the screen display. Delicate and lifelike.
4. LED display screen combined with video processor
The LED video processor can use advanced algorithms to modify signals with poor image quality and perform a series of processes such as deinterlacing, edge sharpening, and motion compensation to enhance image display details and improve picture display quality. The video processor image scaling algorithm is used to ensure that the clarity and gray level of the video image are maintained to the greatest extent after the video image is scaled. In addition, the video processor is also required to have rich image adjustment options and adjustment effects to improve the image. Brightness, contrast, and grayscale are processed to ensure that the LED display screen outputs a soft and clear picture.
