The Structure and Components of cobchina led displays

cobchina led display is made up of two parts: Main cobchina led panel which is composed by several cobchina led display units(cobchina led cabinet or cobchina led panel)that can connected together. This part is the main body of the cobchina 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 cobchina led screens to satisfy different application environments with diverse requirements.( such as video processor and multifunction card).

The Structure of the Screen:

1. cobchina led module

No matter indoor or outdoor cobchina led display, they all composed by cobchina led modules. cobchina led modules are include( cobchina 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 display 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 instalcobchina led inside the computer, the receiving cards should be instalcobchina led 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 display 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 videocard of full color cobchina led screen not only bear the basic functions of computer videocard, but can also output RGB digital signals and row, field and blanking signals to the host controller. Besides functions the same as the special videocard, 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.
