Analysis of the four accessories of full color LED display
Full-color LED display is assembled by many accessories. AVOE company will analyze the four major accessories of full-color LED display for you:
1. Power supplier:
The stability and performance of the power supply determine the performance of the display, and the power supplies of various models are also particular about it. The power required for the LED display is calculated based on the power of the unit board, and various models have different needs.
According to the size of the cabinet, a plurality of unit boards form a cabinet, and the multiple cabinets are assembled into a screen. The cabinet is professionally built, with simple cabinet and waterproof cabinet.
3. LED Module:
The LED module is composed of a kit, a bottom case, a face mask, etc. The full-color LED display is composed of LED modules, which is the large LED screen we now see.
4. Control system:
The control system is an important part of the display. The video is transmitted to the receiving card of the full-color LED display through the sending card and the graphics card. The receiving card then transmits the signal to the HUB board in sections: a receiving card is installed on the receiving card. Adapter board (also commonly referred to as HUB board), the receiving card transmits data to the adapter board, and then the data on the adapter board is transmitted to the single-row or single-column full-color LED display module through the cable. On the group, then the LED module and the LED module are also connected to the data through a cable. Generally, there are only 8 sockets on an adapter board, which means that one adapter board can only manage the data transmission of 8 rows or 8 columns of LED modules. . If there are more rows or columns, an adapter board can be added to the receiving card. The algorithm for receiving LED indoor full-color displays is different from LED outdoor full-color displays. Because the pixels and scanning methods of LED indoor and LED outdoor screens are different, there are differences in LED receiving cards. LED display control and debugging are mainly related to the LED display control system.
