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 flatness of the display will affect the quality of the displayed image.

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.
