The assembly of the display devices 100, 200 may include the following steps. Firstly, the latching module 22 is fixed on the bottom plate 31. At this time, the side plate 32 is received in the second receiving groove 2217. Next, the optical module 40 is disposed on the bottom plate 31. Again, the display screen 10 is fixed or glued on the supporting subassembly 211. Finally, the movable subassembly 212 is disposed in the entrance 226 and the display screen 10 is pushed toward the latching subassembly 222. The display screen 10 drives the movable module 21 to slide on the second mounting portion 223 or directly on the bottom plate 31 until the latching subassembly 222 is completely received in the first receiving groove 213, this achieves engagement between the display screen 10 and the backplane 30.
The disassembling of the display devices 100, 200 may include the following steps. Firstly, the display screen 10 is pushed in an opposite direction. The display screen 10 drives the removable attachment structure 20 to slide toward the entrance 226 until the latching subassembly 222 is completely detached from the first receiving groove 213. Secondly, the display screen 10 and the movable module 21 are moved vertically upward from the entrance 226, to disassemble the movable module 21 from the latching module 22.
With the above configuration, whilst the latching module 22 includes the movable module 21 the latching module 22 is independent from the movable module 21. The latching module 22 includes the latching subassembly 222. Thus assembler can put the movable module 21 into the latching module 22 through the entrance 226 and can drive the movable module 21 to slide on the second mounting portion 223 or directly on the bottom plate 31. Assembly and disassembly of the movable module 21 in relation to the latching module 22 can be achieved by sliding.
