At present, the red, green, blue, orange and yellow LEDs, which are required for color display, have reached candela level luminous intensity, achieving ultra-high brightness and panchromatic, which makes the outdoor full-color display of LED become a reality. The luminous brightness is higher than 1000mcd, which can meet the needs of outdoor all-weather and all-color display. The sky and ocean can be displayed by LED color screen to realize 3D animation. The new generation of red, green and blue ultra-high brightness LEDs have achieved unprecedented performance.
At present, outdoor billboard pixels are composed of red / Green / blue three primary colors (primary colors) of many single tube LEDs. The commonly used finished products are pixel tube and pixel module. The pixel size is mostly 12-26mm, and the pixel composition is: 2R / 3R / 4R for monochrome, 1r2yg / 1r3yg / 1r4yg for pseudo color, and 2R1G1B for true color.
1、 Design principle of outdoor billboard system
1. Structural design principles
2. Brightness and color matching basis
3. Reliability design principle
4. Safety design principle
5. Design principle of easy management and operability
2、 Screen installation mode
Wall mounted: that is, the back of the display screen is against the wall and fixed on the wall. This method is common and easy to implement.
Sitting up: that is, the display screen is sitting on the platform. This method is the most easy to implement, and it should be preferred when conditions permit.
Mosaic: that is, the display screen is embedded in a wall frame. This method is rare, if the depth of wall depression is not enough, its maintainability must be considered.
Side hanging type: the display screen is stressed on both sides and is hung between two buildings or columns. This method is often used for screen hanging in open space, and the two columns are built according to the hanging requirements of screen body.
3、 Structural design
1. Material selection
The angle steel is used as the main material of the screen frame for anticorrosion and fire resistance treatment.
2. Box structure
It adopts large box structure, the box material is polished, galvanized and sprayed with plastic, and has waterproof / corrosion resistance function. The box has the characteristics of thin thickness, light weight, high strength, and adopts positioning column technology to ensure the installation accuracy.
3. Frame structure
Due to the standard box structure, the screen frame structure is simple, the positioning accuracy and the installation process of the screen body are easy to control, and the flatness of the whole screen is ensured.
4. Connection structure
It is simple and easy to use the joint mode of welding and connecting parts, which can ensure the connection strength and improve the installation efficiency of the screen body.
