Shenzhen Ousman Lighting Technology Co., Ltd. technical support, so simple steps! Teach you how to improve the clarity of the full-color LED display.

 

 

 

One, 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, the clearer the image, the more bright and gorgeous color. High contrast is of great help to the clarity, detail and gray level of the image. In some text and video displays with large black and white contrast, high contrast full-color LED display has advantages in black and white contrast, clarity, integrity and other aspects. Contrast has a greater effect on the performance of dynamic video, because the light and shade conversion in a dynamic image is faster, and the higher the contrast, the easier it is for the human eye to distinguish the conversion process. In fact, the contrast of full-color LED display is mainly to improve the brightness of full-color LED display and reduce the surface reflectivity of the screen, but the brightness is not the better, too high, but will backfire, light pollution has become a hot topic, too high brightness will have an impact on the environment and people. The LED panel and LED light emitting tube are processed with special technology, which can reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display.

         

 

Grayscale level refers to the brightness series that can be distinguished from the darkest to the brightest in the single primary color brightness of the full-color LED display. The higher the gray level of the full-color LED display, the richer the color and the more gorgeous the color; On the contrary, the display color is single and the change is simple. The increase of gray level can greatly enhance the color depth, so that the display level of image color increases geometrically. The gray control level of LED is 14bit~16bit, which makes the image level resolution detail and display effect of high-end display products reach the world advanced level. With the development of hardware technology, LED gray level will continue to develop to a higher control precision.

 

 

 

Minimize the dot spacing of the full-color LED display screen. Minimize the dot spacing of the full-color LED display screen, which can improve its clarity. The smaller the dot spacing of the full-color LED display screen, the more delicate the picture display is. However, this point, must have mature technology as the core support, its input cost is relatively large, the production of full-color LED display price is also high, but fortunately now the market is also developing towards small-spacing LED display.
