LED display is a large number of two LED tube array together with the display. It is a kind of control by the semiconductor light-emitting diode display, light off the light to display the characters. Used to display text, graphics, images, animation, market, video, video signals and other information display screen.
The main requirements of the production of LED display materials are: circuit boards, light-emitting diodes, 138,245D, 4953, driver IC, capacitors, resistors, masks, bottom shell, bracket, magnetic column, waterproof plastic, waterproof pad, Cable, power supply, power supply, power supply, cabinet, steel structure, control system (synchronous receiving card, send card, adapter board; asynchronous card).
