Description
technical field [0001] The present invention relates to the technical field of data transmission and display, in particular to a wireless transceiver, a display case and a circuit assembly. Background technique [0002] In the LED display control system industry, the display boxes basically use wired methods such as network cables for signal transmission. With the continuous development of LED display technology, the pixel pitch of the LED display is getting smaller and smaller, and the screen area is getting larger and larger, which means that the number of display boxes used in the LED display is increasing. The number of wires will also increase substantially. The crystal head of the network port is easy to be damaged, and a large number of network cable connections are required for the subsequent debugging and maintenance of the staff, which will cause great troubles for the staff. These have always been the pain points of the LED display control system industry and nee...
