What is LED display contrast

What is LED display contrast? The larger the contrast of the LED display, the clearer the image and the brighter the color; the smaller the contrast, the blurrier the image and the more beautiful the color. How to improve the contrast of the LED display? LED display contrast = white brightness / dark brightness. Therefore, increasing the contrast of the LED display is mainly to increase the white brightness of the display and reduce the black brightness of the display. The higher the brightness parameter of the LED display, the higher the brightness of the white and the higher the contrast ratio, but too high brightness may cause light pollution.

Moreover, the brightness is too high, and the power consumption is relatively increased. Therefore, in the actual engineering operation, the brightness and contrast will be considered at the same time, so that the brightness and contrast can meet the requirements of customers. In addition, the use of materials and processes such as black LED lamp beads, deep black masks, and deep black frames can reduce the dark brightness of the display screen and improve contrast.
