LED screen (outdoor advertising, display) by the application of different places, more or less can be particularly outdoor billboards and outdoor screen categories. As the outdoor LED billboard application of the indoor environment is different from the screen, and bad environmental conditions, the nature of the LED light-emitting materials and has a high cabinet. Generally speaking, outdoor billboards to be used in ultra-bright LED light-emitting materials, high-liang (UHB) is the luminous intensity of 100mcd meet or exceed the LED, also known as the candela (cd) level LED. A1GaInP high-brightness InGaN LED and development have progressed very rapidly and has now reached conventional materials GaA1As, GaAsP, GaP can not reach the level of performance.
At present, the color display required for the three primary colors red, green, blue and orange, yellow multi-color LED's have reached the level of luminous intensity candela, to achieve a super high brightness, full color, LED so that outdoor all - Color display a reality. LED brightness has been higher than 1000mcd, all-weather outdoor meet, the need for full color display, LED large-screen color can be expressed in the sky and the sea, the realization of 3D animation. Red and Green next-generation, ultra-high brightness blue LED to achieve unprecedented performance.

Outdoor advertising pixels by the current red / green / blue three primary colors (color), many of the one-tube LED structure, pixels are commonly used product tube and pixel structure of the two modules. Pixel size for more than 12-26 mm pixel: monochrome to 2R/3R/4R, pseudo-color in order to 1R2YG/1R3YG/1R4YG, true color, and other components in the form of 2R1G1B to the majority.

First, outdoor billboard system design principles

1. Structural design principles

2. Brightness and color matching basis

3. Reliability of the design principles

4. Safety design principles

5. Manageability and operational design principles

Second, to install screen-way

IMR: the display back wall and fixed in the wall. This way for the common way, and make it easier to achieve.

Vertical take: the display screen sitting on the platform. This way most likely to achieve in terms of the license occasion should give priority to the use of such installation.

Embedded: the display screen mounted on the wall of a box. This approach is rare, if not depth of depression wall, depends on its maintenance.

Body-Pack side: the display screen on both sides of the force, hung on the side of the building or post between the two. This approach often used in the open space to fly-screen, the screen on the basis of the two post-suspension request structures.

Third, structural design

1, material selection

Used as a screen-angle steel framework of the main material for anti-corrosion, fire-resistant handle.

2, the cabinet structure

Large box structure of the cabinet grinding material, zinc, spray to deal with a waterproof / corrosion-resistant features. Box has a thickness of the thin, light weight, high strength, the use of technology to ensure the installation of column positioning accuracy and so on.

3, frame structure

As the standard structure of the box, making a simple screen-frame structure, positioning and precision-screen installation process easy to control, to ensure the smoothness of the whole screen.

4, connecting structure

And the use of welding to connect the pieces and connected way is simple, can be linked to ensure that the intensity and at the same time improve the efficiency of the screen to install the body.

Fourth, protection system design

1, the safety power distribution system

a. on b. anti-static electricity systems design c. Mine Design

2, the structural safety of the design-screen

a. wind b. design earthquake design c. waterproof design d. moisture / condensation anti-dust-proof design e. Design f. Anti-oxidation / corrosion resistant design

3, temperature control system design

A. Ping-cooling systems and high temperature anti-design

a. an excellent choice b. drive to improve the design process c. complete system of protective equipment d. advanced technology protection system: the "dynamic cooling" technology, convection heat-sealed, air-conditioning cooling-heat internal convection

Ping-B. anti-low-temperature design
