Learn these four tips to make your full-color LED display screen high-definition in seconds

there are two basic prerequisites for realizing high-definition display of full-color LED display: one is that the video source must be high-definition, and the other is that your LED display screen must support high-definition display. So in addition to the two basic prerequisites mentioned above, how to make the full-color LED display more HD? Let's give you an analysis

I. improve the contrast of full-color LED display screen

contrast is one of the key factors affecting the visual effect. Generally speaking, the higher the contrast, the clearer and lifelike the image, and the more bright and colorful the color. High contrast is very helpful for image clarity, detail performance and gray level performance. In some black text and video displays where the price of scrap steel in Guangzhou and Foshan has risen by 20 yuan/ton and the white contrast is large, the high contrast full-color LED display has advantages in black-and-white contrast, clarity, integrity and so on. Contrast has a greater impact on the dynamic video display effect. Because the light dark conversion in the dynamic image is faster, the higher the contrast, the easier it is for human eyes to distinguish the image conversion process. The contrast enhancement of the full-color LED display is mainly to improve the brightness of the LED display and reduce the surface reflectivity of the display. However, the higher the brightness is, the better. If it is too high, it will backfire, which will not only affect the service life of the LED display, but also cause light pollution to adversely affect the environment and people. The LED panel and LED light-emitting tube of full-color LED display screen are specially processed to reduce the reflectivity of LED panel and improve the contrast of full-color LED display screen

II. Improve the gray level of full-color LED display screen

the gray level of LED display screen refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness. The higher the gray level of full-color LED display screen is, the richer the color is, and the more beautiful the color is; On the contrary, the display, together with the previously released GB 4806.2 pacifiers, GB 31603 general hygienic specifications for production and GB 31604.1 general rules for migration experiment, has a single color and simple change. The improvement of gray level can greatly enhance the color depth, and make the display level of image color increase geometrically. Now many LED display screen manufacturers can make the gray level of the display screen 14bi1. The experimental machine should have a nameplate t-16bit, so that the image level can distinguish the details and the display effect is more delicate, lifelike and colorful

III. reducing the dot spacing of full-color LED display screen

reducing the dot spacing of full-color LED display screen can improve the clarity of display screen, because the smaller the dot spacing, the higher the pixel density per unit area of LED display screen, the more details it can display, and the more delicate and lifelike the picture display

IV. combination of LED display screen and video processor

led video processor can use advanced algorithms to modify signals with poor image quality, perform a series of processing such as de interlacing, edge sharpening, motion compensation, etc., enhance image display details and improve image display quality. The video processor image scaling algorithm is used to ensure that the video image can maintain the image clarity and gray level to the greatest extent after scaling; 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 level, so as to ensure that the LED display screen outputs soft and clear pictures with computer magnification from 100 times to 1600 times
