[0008] As a further improvement to the present invention, support plates are provided on both sides of the horizontal row mother and the vertical row mother.

[0009] As a further improvement to the utility model, the support plate is an insulating plate with a plurality of heat dissipation openings.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model solves the problem of replacing the display screen by changing the original method of fixing the display screen on the circuit board to a method of arranging a header on the circuit board and then plugging the display screen on the header, thereby reducing the problem of replacing the entire circuit board and saving costs.

[0012] The utility model arranges support plates on both sides of the mother row, so that the mother row is not easy to tilt or deform, and the installation of the display screen is more firm. BRIEF DESCRIPTION OF THE DRAWINGS
