1. Dead point

The dead point of the led display is to emphasize the single point that is always bright or often black on the display nowadays. The key points of the dead point are determined by the quality of the die. The lower the dead point, the higher the visual effect of the display

2. Chroma

Chromaticity is very harmful to indoor LED display screens. Too high chromaticity can easily damage the body’s vision and health. Too low chromaticity can cause unclear display of the screen image. Normally, the chromaticity of indoor led display is 800cd/㎡-2000cd/㎡. Different brands of led display products have different chromaticity.

3. Color oxidation

The oxidation of the color of the display screen means that the color displayed on the display screen must be consistent with the color of the playback source, so as to ensure the reality of the image.

Fourth, flatness

The flatness of the display will endanger the quality of the displayed image. The flatness of the car body surface of the indoor LED rental screens in the industry is maintained within ±1mm, and some protrusions or depressions on the car body surface will cause blind spots in the viewing angle of the display screen. The quality of flatness is determined by the processing technology, and LED display manufacturers should pay attention to this problem when manufacturing.

Fifth, the view angle of Lishi

The size of the viewing angle of the led display screen immediately decides a few of the target groups of the led display screen. The larger and higher the viewing angle of LASV, the wider the scope of the target group, and the viewing angle of LSV is jeopardized by the LED die packaging method. Therefore, pay attention to the packaging method of the die when choosing indoor LED rental screens.
