How to adjust the clarity of the LED display

2021-04-24

1. gray scale

The gray level refers to the brightness level from the darkest to the brightest in the brightness of the single primary color of the LED display. The higher the gray level of the LED display, the richer the color and color; on the contrary, the lower the gray level , indicating that the color is relatively single. Increasing the gray level can increase the color depth to a large extent and better present the color of the image. The gray scale of LED display is 14bit~16bit. With the advancement of technology, LED gray scale will continue to develop towards higher control accuracy.

2. the improvement of contrast

One of the key factors affecting the visual effect of LED displays is contrast. Generally speaking, the higher the contrast, the clearer the image and the richer the color. High contrast has an important influence on image clarity, detail performance, and gray level performance. The advantages of high-contrast LED displays are reflected in the black and white contrast, clarity, and integrity. And the contrast will have a greater impact on the dynamic video display effect, because the light-dark transition in the dynamic image will be faster, so the higher the contrast, the easier it is for human eyes to distinguish the conversion process. There are two main ways to improve the contrast of the display:

2.1. Improve the brightness of the LED display. The contrast can be improved by increasing the brightness of the LED display. But pay attention to some occasions, such as indoor LED display brightness is not as high as possible, because the brightness is too high, it will form light pollution, it will cause damage to everyone's eyesight.

2.2. Reduce the reflectivity of the LED display surface. Reducing the reflectivity of the LED panel can improve the contrast of the LED display, mainly through special processing of the LED panel and the LED light-emitting tube.
