LED electronic screen is divided into two parts: graphics screen and video movie screen, which is composed of LED matrix block. The graphic screen can be synchronized with the computer to display Chinese characters, English text and graphics. Video screen, graphics, movie, real-time, synchronous, clear information transmission, 2D, 3D animation, video, TV, DVD / VCD program and live scene controlled by microcomputer IC. It has the advantages of high brightness, low operating voltage, low power consumption, miniaturization, easy matching of integrated circuit, simple driving, long life, impact, stable performance and so on.
LED electronic screen is widely used in stations, docks, airports, shopping centers, hospitals, hotels, banks, securities markets, construction markets, industrial enterprise management and other public places. Other display technologies (such as liquid crystal display, mechanical and electrical structure) show that they have specific uses in some specific locations, but the LED electronic screen has proved to be the most reliable, effective, energy-saving, brightest and easy to realize. LED is the abbreviation of LED. The principle of LED light-emitting technology is that some semiconductor materials emit light of a specific wavelength when they pass the current. This kind of electricity to light conversion efficiency is very high, the chemical treatment of the materials used is different, and the LED can be obtained through different brightness and angle of view. Adjust the display mode of led to display text, graphics, images, animation, market, video, video signal and other information on the screen.
