Outdoor full-color LED display stage meeting room high-definition advertising large screen

The LED display is a flat-panel display, which is composed of multiple small LED module panels, and is used to display various information such as text, images, videos, and video signals.

LED electronic display integrates microelectronics technology, computer technology, and information processing. [1] has the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable work, etc. It is widely used in commercial media, cultural performance markets, Sports venues, information dissemination, news releases, securities transactions, etc., can meet the needs of different environments.

The LED display screen is an electronic display screen composed of LED dot matrix. By turning on and off the traffic light beads to replace the screen display content forms such as text, animation, pictures, and video, the timely conversion is performed, and the component display control is performed through a modular structure. It is mainly divided into display module, control system and power supply system. The display module is a dot matrix of LED lights to form a screen to emit light; the control system is to control the on and off conditions in the area to convert the content displayed on the screen; the power system is to convert the input voltage and current to meet the needs of the display screen. the

The LED screen can realize the transformation between different forms of various information presentation modes, and can be used indoors and outdoors, and has incomparable advantages over other display screens. With the characteristics of high luminous intensity, low working power consumption, low voltage demand, small and convenient equipment, long service life, stable impact resistance and strong resistance to external interference, it has developed rapidly and is widely used in various fields.

Compared with other large-screen terminal displays, the LED display has the following characteristics:

1. High brightness: the brightness of the outdoor LED display is greater than 8000mcd/㎡, which is the only large-scale display terminal that can be used outdoors all day; the brightness of the indoor LED display is greater than 2000mcd/㎡.

2. Long life: The life of LED is more than 100,000 hours (10 years). This parameter generally refers to the design life, even if the brightness is dim;

3. Large viewing angle: the indoor viewing angle can be greater than 160 degrees, and the outdoor viewing angle can be greater than 120 degrees. The size of the viewing angle depends on the shape of the LED light emitting diode. 

4. The screen area can be large or small, as small as less than one square meter, and as large as hundreds or thousands of square meters;

5. Easy to interface with computer, rich in supporting software.

LED display performance is superior:

1) The luminous brightness is strong, and when the sunlight directly hits the screen surface within the viewing distance, the display content is clearly visible. Super gray scale control has 1024-4096 gray scale control, and the display color is above 16.7M. The color is clear and vivid, and the three-dimensional effect is strong.

2) Static scanning technology, using static latch scanning mode, high-power drive, fully guarantees the luminous brightness.

3) Automatic brightness adjustment With automatic brightness adjustment function, the best playback effect can be obtained in different brightness environments.

4) Fully adopt imported large-scale integrated circuits, the reliability is greatly improved, and it is convenient for debugging and maintenance.

5) Advanced digital video processing, technology distributed scanning, BSV liquid crystal splicing technology high-definition display, modular design/constant current static drive, automatic brightness adjustment, ultra-bright solid color pixels, clear image, no jitter and ghosting, Eliminate distortion. Video, animation, chart, text, picture and other information display, network display, remote control.

The world's largest LED display is a 9,500-square-meter giant LED display outside the opening ceremony venue of the 2010 Shanghai World Expo.

The LED display screens on the market are all pursuing thinner and lighter. The LED transparent screen exhibited in the theme pavilion of the 2010 Shanghai World Expo is a successful case. The display area is 400 square meters, and it is made of P18 surface mount technology. Die-casting aluminum box structure, what is even more impressive is the ingenious installation method.
