LED display is made up of two parts: the led cabinets and the display control system.

LED cabinets including LED modules, power supply, control cards, power cables and signal flat cables, it’s the LED display unit ( if clients make modules installation display, the led modules are the display units ).

Another part is the control system. the control system can also be divided into two parts: control board( hardware) and control system( software).

The control board includes the sending card,receiving cards and computer.

Multifarious displays with different specifications, control systems and different control technology ( such as video processor and multifunction card) can be constituted into various kinds of LED screens to satisfy different application environments with diverse requirements.

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 shell ).

Different modules have different sizes and shapes, if clients want special size or shape modules,you can ask yonwaytech R&D team to create a new mold to make the required modules, this will cause extra cost.

2. Display Cabinets
Display cabinets the main body of the screen.

It is made up of heat-emitting materials and driving circuit.

There are die casting cabinets with fixed sizes design for rental display and there are steel cabinets and aluminum cabinets with customized sizes for common display.
YONWAYTECH provide any kinds of tailored service for your need.

3. Display Control System
Display control systems mainly include sending cards, receiving cards and computer.

The sending card should be installed inside the computer or video processor, the receiving cards should be installed inside the cabinets, usually we design one cabinet with one receiving card so that to make full use of the receiving card loading capacity.

4. Switching Power Supply
It is used to transform the 220V or 110V alternating current into 5V output direct current to support the LED modules working.

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
It’s function 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 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.
