Definitions
- the side of the first limit protrusion facing the second limit protrusion is the first straight edge
- the side of the second limit protrusion facing the first limit protrusion is the first straight edge.
- Two straight sides, and the first straight side is parallel to the second straight side, and is inclined relative to the side of the display panel.
- the display module includes a display panel and a driving circuit board disposed on the non-light-emitting side of the display panel, the driving circuit board is provided with a cable connector;
- the disassembly and assembly of the module greatly reduces the time-consuming for replacement of cables and other components; at the same time, by arranging the fastening assembly 600 on the back plate 300, when the movable cover plate 500 closes the opening 400, The movable cover plate 500 is further tightened, which effectively enhances the stability and sealing of the cable opening structure on the back of the display device, realizes the effective isolation of man and machine, and improves the service life of the internal components of the module and the use of personnel.
- the safety factor does not take up space and has strong safety.
- the block 610 When the cable 10 needs to be replaced, the block 610 is pulled outward, so that the distance between the block 610 and the backplane 300 in the direction perpendicular to the backplane 300 increases, so The free end of the stopper 610 rotates around the rotating shaft 620 and escapes from the gap between the first limiting protrusion 630 and the second limiting protrusion 640, and the movable cover plate 500 is turned over with the rotating rod 700 as the axis (as shown in FIG. 3 to FIG. 4 , it can be turned up to 120°) to expose the cable connector 210 of the drive circuit board 200 of the whole machine;
- the display device provided by the embodiment of the present disclosure can also bring about the beneficial effects brought by the backplane 300 provided by the embodiment of the present disclosure, which will not be repeated here.
