Five points that LED display needs to pay attention to

Dead point

The dead point of the LED display is a single point that is always on or black on the display. The number of dead points is mainly determined by the quality of the die. The lower the dead point, the better the display effect of the display

Brightness

Brightness has a great influence on indoor LED display screens. Too high brightness can easily damage human vision and endanger human health. Too low brightness will cause unclear display of the screen image. Generally speaking, the brightness of indoor LED display is 800cd/㎡-2000cd/㎡. Different brands of LED display products have different brightness.

Color reproduction

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

Flatness

The flatness of the display will affect the quality of the displayed image. The flatness of the cabinet surface of the indoor LED rental screens in the industry is kept within ±1mm, and the local protrusions or recesses on the surface of the cabinet will cause a blind angle in the viewing angle of the display. The quality of flatness is determined by the production process, and LED display manufacturers should pay attention to this issue during production.

Viewing angle

The viewing angle of the LED display directly determines the audience of the LED display. The larger the viewing angle, the better, and the audience will be wider. The viewing angle is affected by the LED die packaging method. Therefore, when choosing indoor LED rental screens, attention should also be paid to the packaging method of the die.
