It can be used to display various static information such as text and graphics and various dynamic information such as animation and video.

[0003] During the production and processing of the LED display driver board, in order to ensure the quality of the LED display driver board, it is generally necessary to test the LED display driver board. The corners of the LED display driver board are generally provided with through holes. When the existing test device is used, the LED display driver board is first placed on the base of the test bench, and then the limit work of the LED display driver board is completed by the rotating pressing pieces on both sides of the base that can be pressed by the rotating machine. Then, one end of the transmission line is driven by the moving device to be inserted into the socket of the LED display driver board, so that the LED display driver board is tested by the testing mechanism. In the existing test device, the rotating pressing piece presses the LED display driver board downward, and the force applied by the transmission line when docking with the LED display driver board is horizontal.
