The original connecting component is replaced by solder paste welding, so that the fixing effect and the electric connecting effect are realized, and the volume of the control unit 4 is obviously reduced. Meanwhile, the modularized design of the control unit can be realized, each display screen unit is a complete display screen, and all functions of the display screen can be realized, so that the display screen unit is more convenient and rapid to assemble and maintain in the process, and only the display screen unit with problems is required to be closed and disassembled in the process of maintenance, thereby ensuring that the display screen can work normally when a part of display screen units are absent, and improving the utilization rate. In addition, due to the reduction of the volume of the control unit 4, the maximum included angle formed by the connecting line from any point on the rear cover 3 to the outer contour of the first surface and the first surface can be reduced, thereby being beneficial to reducing the minimum value of the included angle of the chamfering structure.
The foregoing is merely exemplary of the invention, and it should be noted herein that modifications may be made by one of ordinary skill in the art without departing from the inventive concept. But these are all within the scope of the present invention.
