LED display is also called electronic display screen or floating word. LED dot matrix is ??composed by red green blue light blinking beads to display text, images, animation, video, content can be replaced at any time, the various parts of the components are modular structure of the display device. Normally by the display module, the control system and power system. Display [1] module lattice composed by LED lights constitute charge light-emitting display; control system by controlling the light off the appropriate area, allowing the screen to display text, pictures, video and other content, a constant dance card is mainly to play the animation; Power system is responsible for the input voltage and current into the required voltage and current display LED display can show changes in the numbers, text, graphics and video; not only the indoor environment can also be used for outdoor environment, with a projector, TV wall, LCD Screen incomparable advantages. The reason why LED widespread attention and rapid development, is that it itself has the advantage inseparable. To sum up these advantages are: high brightness, low voltage, low power consumption, small size, long life, impact resistance and stable performance. LED is extremely broad prospects for development, the current is moving higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, full color direction. * LED display performance super strong brightness in the visible surface of the screen away from direct sunlight the display is clearly visible Super 1024-4096 grayscale gradation control have control over 16.7M display colors vivid color three-dimensional sense of strong static scanning technology uses static Latch scanning brightness light-emitting power driver fully guaranteed automatic brightness adjustment with automatic brightness adjustment function for optimal playback in different light conditions fully imported LSI reliability are increased ease of commissioning and maintenance
