Typical technical parameters of LED display video walls
1. Indoor screen series
    The indoor LED screen area is generally less than ten square meters, the point density is high, and it is used in non-direct sunlight or lighting environment. The viewing distance is several meters away, and the screen body does not have sealing and waterproofing ability. According to the control method and display color, it can be divided into the following types:
    ● Indoor full color video screen
        ★ Adopt independent point-by-point correction technology to ensure uniformity between points.
        ★ The light-emitting point of the display panel adopts a column-shaped flat-headed light-emitting diode. After testing, the vertical and horizontal full-view angles can reach 150 degrees.
        ★ The reflector that forms the lamp panel is made by opening the mold and seamlessly matches the light-emitting point. The finished product can be made with minimal surface height error.
        ★ Using LEDs, the brightness of the light is 6-8 times the brightness of the light-emitting chip.
        ★ The heat of the LED is mainly lost from the metal pin, which determines the display panel has good heat dissipation performance.
        ★ Bad LEDs can be replaced one by one, without affecting the use of other LEDs and reducing maintenance costs.
        ★ Using the latest technology level video control system, the display color is bright and clear.
