Indoor LED displays are used in indoor environments. Such displays have moderate brightness, large viewing angles, close color mixing distance, light weight, and high density, and are suitable for closer viewing.

The outdoor screen area generally ranges from a few square meters to tens or even hundreds of square meters. The dot density is relatively sparse (mostly 2500-10000 dots per square meter), and the luminous brightness is 5500-8500cd/square meter (different orientations, different brightness requirements), which can be used in sunlight When used under direct sunlight, the viewing distance is tens of meters away, and the screen has good wind and rain resistance and lightning protection capabilities. Semi-outdoor screen is between outdoor and indoor. Step 4: It has high luminous brightness and can be used outdoors in non-direct sunlight. The screen body is sealed to a certain extent, usually under the eaves or in the shop window.

(2) According to the color, it is divided into single color, double primary color, and three primary color (full color). Monochrome refers to the luminescent material of the display screen with only one color, mostly single red. It can also be yellow-green in some special occasions (such as funeral homes). ). The dual-color LED display is composed of red and green LED lights. The dual-color display with 256-level grayscale can display 65,536 colors (the dual-color screen can display 3 colors of red, green and yellow).

The full-color LED display consists of red, green and blue LED lights, which can display white balance and 16,777,216 colors. 1. Unit board module splicing seam: the size of the unit board gap splicing seam is the same, and ≤1mm. The attenuation characteristics are not only related to the characteristics of the red, green, and blue LEDs, but also the current used, the PCB board heat dissipation design, and the ambient temperature of the display screen all have an impact on the attenuation. The company relies on its strong resource integration capabilities to establish a good strategic partnership with the manufacturer of MLED display raw materials.
