LED Display makes it possible that deeply expanding the advertising markets and adequately revealing the enterprise. There are a lot of advantages of LED Display : easy installation(removable), less investment, that the traditional wired screen couldn’t compare to. With the advantage of wireless offline receiving, storage and displaying information, LED screen uses the comprehensive service mode to take the place of the single service mode of traditional electronic screen, which is only available in settled place but impossible in any other places.

Fullcolor LED Display, also called Three Primary Colors LED Screen, of which the smallest display unit is made up of red, green and blue colors. The working principle is the same with the monitor of computers, and it can show the original colors. Every smallest unit of fullcolor LED display consists of red, green and blue LED luminotrons. LED SIGNS matches with the computer dot by dot, with excellent display effect, high reliability and stability. We can correct the white balance of three primary colors by the patent correction technology, ensure the display stability by the most advanced wave soldering machines, what’s more, there is no mosaic in the LED panel.

High level grayscale control system of LED Display Screen
The grayscale control is vital to the display effect, so we use hardware FPGA to code the 4096 grayscale, and then take 256 grades from them. It’s real time and improves the display effect greatly. We use the technology of anti-jamming to video receiving circuit, storage circuit, high-speed circuit and scanning control circuit, and improve the refresh speed to 300Hz, to make the images exquisite and steady, to ensure the effect in true color with 24 digital figures to show the beauty of the nature.

We use unique dynamic white balance control system, to make the temperature of colors less than ±520K on the condition that the dynamic brightness is 10%-100%, to make screens reach white balance in all kinds of light in different circumstances when keep the best viewing distance. White balance is the key to measure the display effect, and the colors’ temperature standard of Display products is D65. Intellectualized and automatic brightness control system can control the brightness of screens according to the outside brightness get by the photoreceptor...

All components for the production are original and sifted carefully; photovoltaic components are all original imported chips (eg. Nichia from Japan, Toyota, HP from USA, CREE, etc); electronical components are imported from famous factories abroad (eg. HARRIS, TOSHIBA, ALLEGRO, MOTOROLA, TEXAS, PHILIPS, ALTERA); and control system adopts large scale integrated circuits EPGA, to make it more reliable, while much smaller.Nice power distribution system is an important condition to achieve the reliable work of LED display screens. LED Display Screen owns exclusive PDS...

LED Display Screen is a kind of high-tech products including photoelectric technology, micro-electric technology, computer technology and information processing technology as well as display technology. According to the applications, it includes Indoor LED, Semi-outdoor LED, and Outdoor LED; According to the primary colors, Single color LED, Dual color LED, and Full color LED; According to the functions, Strip LED Screen, Image-text LED, and Multimedia LED. All the LED screens are designed in modules, and the display part connects well with the control part, with good compatibility among systems.
