  Common LED display screen by several composable splicing unit module, unit, display cabinet, display board or unit box body, a variety of specifications of the display board or unit controller in different control techniques can be composed of many kinds of LED display, such as indoor LED display and outdoor LED display, in order to satisfy the different environment, the needs of different display requirements.In a more complex synchronization video LED display, for example, the display system is composed of eight basic elements:
  1, The structure of the metal framework: indoor screen generally consists of Angle of aluminium alloy aluminum or aluminum square tube within the framework of display board etc, all kinds of circuit board and switch power supply, outside the borders using dark brown aluminum alloy square tube, stainless steel or aluminum alloy package, or sheet metal.Outdoor screen frame according to the screen size and bearing capacity for Angle or i-steel commonly, the casing outside the aluminum-plastic plate can be used for decoration.
  2, Scanning control board: the function of the circuit board is data buffer, compared various scanning signals, and gray level control signals.
  3, Display unit: display the main body of local, composed of luminescent materials and the driving circuit Indoor screen is a variety of specifications of the unit display board, outdoor screen is unit housing.
  4, Twisted pair transmission cables: master of display data and various kinds of control signals by twisted-pair cable transmission to the screen.
  5, The main controller, the input RGB digital video signal buffer, gray level transformation, reorganize, and produce various kinds of control signals.
  6, Special display card and multimedia CARDS: besides has the basic function of the computer display card line digital RGB signal output and at the same time, also, blanking signal to control apparatus, etc.Multimedia in addition to the above function can also be the input analog Video signal into digital RGB signals, namely Video collection.
  7, Computer and its peripherals: mainly used for synchronization of video playback.
  8, Switching power supply: all sorts of 220 v alternating current into direct current (dc) to provide all kinds of circuit.
