The LED screen can be divided into two types according to the application place, which can be divided into outdoor billboards and indoor screens. Since the application environment of the LED outdoor billboard is different from the indoor screen, and the environmental conditions are relatively harsh, the LED has a high requirement for the luminescent material and the box. In general, LEDs for outdoor billboards must be super bright luminescent materials, and bright height (UHB) refers to LEDs with luminous intensity of 100 md or more, also known as candela (cd) LEDs. The development of high-brightness A1GaInP and InGaN LEDs is progressing rapidly, and has reached the performance level that conventional materials GaA1As, GaAsP, and GaP cannot achieve. At present, the three primary colors of red, green, blue, and orange and yellow LEDs of color display have reached the candela-level luminous intensity, achieving ultra-high brightness and full color, and making the outdoor full color of the luminous tube. The display becomes a reality. The brightness of the light is higher than 1000mcd, which can meet the needs of outdoor all-weather and full-color display. The LED color large screen can express the sky and the ocean and realize 3D animation. A new generation of red, green and blue ultra-high brightness LEDs have achieved unprecedented performance. The outdoor billboard pixels are currently composed of many single-tube LEDs of three primary colors (primary colors) of red/green/blue. The commonly used finished products have two structures of a pixel tube and a pixel module. The pixel size is mostly 12-26 mm, and the pixel composition is: 2R/3R/4R for monochrome, 1R2YG/1R3YG/1R4YG for pseudo color, and 2R1G1B for true color. First, the principle of outdoor billboard system design 1, structural design principles 2. Brightness and color matching basis 3. Reliability design principles 4. Safety design principles 5. Easy to manage and operability design principles Second, the screen installation method Wall-mounted: the display is placed against the wall and fixed to the wall. This method is a common method and is easier to implement. Side-mounted: that is, the two sides of the display are stressed, and the side is hung between the two buildings or columns. This method is often used for the screen suspension of the open space, and the two columns are built according to the suspension requirements of the screen.

Sitting upright: the display stands on the platform. This method is the easiest to implement, and this type of installation should be preferred when conditions permit.
Mosaic: The display is embedded in a wall frame. This method is rare. If the wall is not deep enough, it must be considered for maintainability.
