LED display screen is made up of two parts: Main led panel which is composed by several led display units(Led cabinet or led panel)that can connected together. This part is the main body of the led display. another part is the controller. the controller can also devided into two parts: control board( hardware) and control system( software).
The control board are include the sending card,receiving cards and computer. Multifarious display panels (or cabinet units) with different specifications and controllers with different control technology can be constituted into various kinds of LED display screen to satisfy different application environments with diverse requirements.( such as video processor and multifunction card).
The Structure of the Screen:
1. Led module: No matter indoor or outdoor led display, they all composed by led modules. Led modules are include( led lamps, driving IC, pcb board and module frame). its size can not be changed easily.
2. Display Panel Display Panel is the main body of the screen. It is made up of light-emitting materials and driving circuit. The LED display screen panel of indoor and outdoor screen are unit cabinet.
3. Display Controller Display controller are mainly include sending card, receiving cards and computer. The sending card should be installed inside the computer, the receiving cards should be installed inside the cabinets. usually one cabinet needs one receiving card.
4. Switching Power Supply It is used to transform the 220V or 110V alternating current into all kinds of direct current to support various circuits. 5. Transmitting Cables The led display screen data and all kinds of controlling signals generated by the host controller are transmitted through twisted-pair cables to the screen.
6. Scanning Control Board The function of it is to cushion the data, generate all kinds of scanning signals and duty cycle grey scale control signals.
7. Special Videocard and Multifunction Card The special video card of full color LED screen not only bear the basic functions of computer video card, but can also output RGB digital signals and row, field and blanking signals to the host controller. Besides functions the same as the special video card, multifunction card can also change the input simulated video signals into RGB digital signals (that is the collection of video communication).
8. Other information sources and devices Including computer, TV set, blue-ray disc, DVD, VCD, video camera and recorder and so on.

The full color LED display consists of LED matrix modules. Picture display can display Chinese characters, English text and graphics synchronously with the computer; Video playback using computer control, play a variety of information, graphic. Also can display animation, video, TV, VCD programs and live. Simply put, LED display is composed of a number of display units that can be combined and spliced to form the screen body, plus a set of appropriate controllers. So a variety of specifications of the display board (or unit box) with different control technology of the controller can be composed of many kinds of LED display, to meet the different environment.
LED display1.LED display is divided into indoor LED display and outdoor LED display according to the use environment. Do you know the seven differences between indoor and outdoor LED displays?
2.LED display is divided into single primary color LED display, double primary color LED display and full color LED display.
3.LED display can be divided into 16, 32, 64, 128, 256 levels of gray LED display, etc.
4.LED display is divided into ordinary led display and irregular led display according to the usage scenario.
LED displayThe following is an example of the structure of a complex full color led display
1. Metal frame
Indoor screen is generally made of aluminum alloy (Angle aluminum or aluminum square tube) constitute the inner frame, equipped with various circuit boards such as display panels and switching power supply, the outer frame is made of brown aluminum alloy square tube, or aluminum alloy stainless steel, or sheet metal integration. The outdoor screen frame is generally composed of Angle steel or I-steel according to the screen size and bearing capacity, and the outer frame can be decorated with aluminum plastic plate.
Sostron indoor LED panel-Reta2. Display the unit plate
This is the main part of the screen body, composed of luminous materials and driving circuit. Indoor display is a variety of specifications of the unit display board, outdoor display is the unit box.
3. Master controller
The function is to buffer the input RGB digital video signal, gray transform, reorganize, and generate various control signals.
Sostron outdoor LED display-Ares4. Switch on and off the power supply
The purpose is to change 220V AC into a variety of direct current to provide a variety of circuits.
5. Transmission cable
The display data and various control signals generated by the master controller are transmitted to the display body through the twisted pair cable.
6. Scan the control panel
The function of the circuit board is data buffering, generating various scanning signals and duty ratio gray control signals.
Sostron outdoor LED display-Ares7. Special display card and multimedia card
Full color LED display special display card in addition to the basic function of the computer display card, but also output digital RGB signals and other signals to the master. In addition to the above functions, multimedia card can also change the input analog Video signal into digital RGB signal (that is, video acquisition).
8. Other information sources and their external devices
Including computer, DVD, VCD, video camera, etc.
