[0017] The present invention provides a technical solution: a liquid crystal display module, including a backplane 100, and a liquid crystal display mounting plate 300 disposed directly above the backplane 100. It further includes a liquid crystal display body 400 installed inside the liquid crystal display mounting plate 300 for presenting visual information. The liquid crystal display body 400 is composed of a backlight module, a liquid crystal layer, a polarizer, a color filter, a glass substrate, a transparent electrode, and a driving circuit. As the prior art, it will not be elaborated here. An outer part of the liquid crystal display mounting plate 300 is provided with a module frame 200 for supporting the liquid crystal display mounting plate 300. There is a movable opening between the module frame 200 and the liquid crystal display mounting plate 300 to ensure that the liquid crystal display mounting plate 300 will not touch the module frame 200 during movement. And inside the movable opening, there is a dust-proof partition strip 700 for intercepting dust. One end of the dust-proof partition strip 700 is connected to the module frame 200, and the other end of the dust-proof partition strip 700 is connected to the liquid crystal display mounting plate 300. In this device, it further includes: an adjusting and self-locking mechanism 600 disposed between the liquid crystal display mounting plate 300 and the backplane 100 and used for adjusting the angle of the liquid crystal display mounting plate 300.

[0018] Specifically, the module frame 200 is composed of a plurality of lifting blocks 201 arranged at equal intervals. Two adjacent lifting blocks 201 are in mutual contact and relative sliding. In the middle of the bottom end of the lifting block 201, there is a lifting rod 203 for guiding the lifting block 201.
