Outdoor full-color LED advertising display design: LED large screens (outdoor billboards, LED displays) can be roughly divided into outdoor billboards and outdoor screens according to different applications. Since the application environment of LED outdoor displays is different from indoor LED screens, and the environmental conditions are relatively harsh, naturally there are higher requirements for LED luminescent materials and cabinets. Generally speaking, the LEDs of outdoor billboards must be made of ultra-bright luminescent materials. Brightness height (UHB) refers to LEDs with luminous intensity reaching or exceeding 100mcd, also known as candela (cd) LEDs. The development of high-brightness A1GaInP and InGaN LEDs is progressing very rapidly, and has reached the performance level that conventional materials GaA1As, GaAsP, and GaP cannot reach. At present, the three primary colors of red, green, blue, orange, and yellow LEDs required for color display have reached candela-level luminous intensity, achieving ultra-high brightness and full color, making the outdoor full color of the luminous tube The display becomes a reality. The luminous brightness is higher than 1000mcd, which can meet the needs of outdoor all-weather, full-color display. The large LED color screen can express the sky and the ocean and realize 3D animation. The new generation of red, green, and blue ultra-high brightness LEDs have achieved unprecedented performance. Outdoor billboard pixels are currently composed of many single-tube LEDs with three primary colors (primary colors) of red/green/blue. Commonly used products have two structures: pixel tube and pixel module. The pixel size is mostly 12-26 mm, and the pixel composition: monochrome is 2R/3R/4R, pseudo color is 1R2YG/1R3YG/1R4YG, true color is 2R1G1B and other composition forms. 1. Design principles of outdoor full-color LED advertising display system scheme 1. Structural design principles 2. Brightness and color matching basis 3. Reliability design principles 4. Safety design principles 5. Easy management and operability design principles 2. Outdoor full The installation method of the color LED advertising display screen is wall-mounted: that is, the display screen is backed against the wall and fixed on the wall. This method is common and easier to implement.   Sit and stand: that is, the display screen sits and stands on the platform. This method is the easiest to implement, and this installation method should be preferred when conditions permit.   Mosaic: the display screen is inlaid in a wall frame. This method is rare. If the wall depression depth is not enough, the maintainability must be considered.  Side-hung type: that is, the display screen is stressed on both sides, and it is side-hung between two buildings or pillars. This method is often used for screen suspension in an open field, and the two columns are built according to the suspension requirements of the screen. 3. Outdoor full-color LED advertising display structure design   1. Material selection   Use angle steel as the main material of the screen frame, and carry out anti-corrosion and fire-resistant treatment.  2, box structure    adopts a large box structure, the box material is polished, galvanized, sprayed, and has waterproof/corrosion resistance functions. The box has the characteristics of thin thickness, light weight, high strength, and the use of positioning column technology to ensure installation accuracy.  3. Frame structure   Because of the standard box structure, the screen frame structure is simple, the positioning accuracy and the installation process of the screen are easy to control, and the flatness of the whole screen is guaranteed.  4. Connection structure    adopts the joint method of welding and connecting parts, which is simple and easy to implement, can ensure the strength of the connection, and improve the installation efficiency of the screen. Four, outdoor full-color LED advertising display system protection function design 1. Safety power distribution system a. Power-on system b. Anti-static design c. Lightning protection design 2. Screen structure safety design a. Windproof design b. Shockproof design c . Waterproof design d. Moisture-proof/anti-condensation design e. Dust-proof design f. Anti-oxidation/anti-corrosion design 3. Temperature control system design Outdoor full-color LED advertising display screen heat dissipation system and high-temperature design a. Excellent Driver selection b. Perfect process design c. Complete system protection equipment d. Advanced system protection technology: namely 'dynamic heat dissipation' technology, sealed convection heat dissipation, air conditioning cooling type internal convection heat dissipation B. Outdoor full-color LED advertising display Low temperature protection design of the screen
