An LED display screen is assembled by many accessories.
LED display power supply: the power supply has also increased the sales of power supply under the influence of the rapid increase of LED display industry. The stability and performance of power supply determine the performance of LED display, and the power supply equipped with various models is also exquisite. The power supply required for Tianjin LED display screen is calculated according to the power of the unit board, and the requirements of various models are different.
LED display box: according to the size of the box, multiple unit boards form a box, and multiple boxes are assembled into an LED display. The box is made professionally, including simple box and waterproof box. The rapid development of LED industry also makes the manufacturers of full-color LED display box almost saturated with orders every month, driving the development of box manufacturers.
LED display module: LED module is composed of kit, bottom shell, mask, etc. Tianjin LED display is composed of LED modules, that is, the large LED screen we see now.
LED display control system: the control system is an important part of the LED display. The video is transmitted to the receiving card of the LED display through the sending card and graphics card, and then the receiving card transmits the signal to the hub board in sections: an adapter board is installed on the receiving card, and the receiving card transmits the data to the adapter board, Then, the data on the adapter board is transmitted to the single row or single column LED display module of the LED display box through the cable arrangement, and then the data between the LED module and the LED module is also connected through the cable arrangement. Generally, an adapter board has only 8 sockets, that is, an 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 receiving algorithm of indoor LED display screen is different from that of outdoor LED display screen, because the pixel points and scanning mode of indoor screen and outdoor screen are different, so there are differences in LED receiving card. LED display control and debugging are mainly related to LED display control system
