[0006] Preferably, the rear cover has LED strip mounting holes at both the upper and lower ends, an LED strip is fixed in the LED strip mounting holes, and the power cord of the LED strip is connected to the PCB board.

[0007] Preferably, the outer frame has upper and lower ends with retaining bars for limiting the position of the retaining bars, and the screen is disposed between the retaining bars.

[0008] Preferably, the inner walls on the left and right sides of the outer frame are provided with grooves for engaging the retaining strip.

[0009] Preferably, the stop bar is provided with a clearance groove for avoiding the track.

[0010] Preferably, the gap between the screen and the rear cover is filled with foam.

[0011] Preferably, a hook is fixed in the middle of the wall mount, and a notch is provided on the surface of the rear cover plate. The notch and the outer frame form a hook groove for engaging the hook; or a through hole is provided on the rear cover plate, and the wall mount hook engages with the through hole.

[0012] Preferably, the rear cover has an opening in the middle for the power cord to pass through, and the wall mount has an elongated hole in the middle.

The inner walls on both sides of the outer frame have recesses for embedding the protective transparent screen. The lateral length of the protective transparent screen is greater than the lateral length between the inner walls of the outer frame, so that it can be engaged with the recesses between the inner walls of the outer frame. The protective transparent screen has a transparent window in the middle that is the same size as the screen.

[0014] Preferably, the rear cover plate has several protrusions on its left and right sides, each protrusion having a first screw hole, and the inner wall of the outer frame has several mounting grooves that are adapted to the protrusions. Each mounting groove has a second screw hole that is adapted to the protrusion, and the protrusions and mounting grooves are locked and fixedly connected by screws passing through the first screw hole and the second screw hole.
