Each mounting space 6 has a protruding positioning part 61 on one of its inner side walls. The positioning part 61 is located on the inner side of one corner of the mounting space 6. In this embodiment, the positioning part 61 is preferably located at the upper left corner of the mounting space 6 and is located on the horizontal pressure strip 2, but it can also be located on the vertical pressure strip 3.

[0021] The LED display module 4 has a base and a PCB board. The dimensions of the mounting bracket 1 are greater than or equal to the outer dimensions of the LED display module 4. The height of the mounting bracket 1 is greater than the sum of the thicknesses of the LED display module 4 and the frameless mask 5. The horizontal pressure strip 2 and the vertical pressure strip 3 are located on the upper part of the mounting bracket 1. The distance between the bottom surface of the horizontal pressure strip 2 and the bottom surface of the vertical pressure strip 3 and the bottom surface of the mounting bracket is slightly greater than the thickness of the LED display module, thereby ensuring that the pressure strips are higher than the PCB lamp surface after placement and fixing, and avoiding lamp collisions.

[0022] Furthermore, each of the transverse pressure strips 2 is provided with a first slot 21 at the bottom of both ends, and the transverse pressure strip 2 is snapped onto the fixing frame 1 through the first slot 21, with the transverse pressure strips 2 arranged in parallel.
