  • Patent number: 8971027
    Abstract: In a display device cabinet, a fixing assembly to join a front panel and a rear panel include a first fixing mechanism that uses attachment screws and a second fixing mechanism that uses no attachment screws, which have a structure that prevents the application of excessive force to engaging openings and protrusions during the assembly process and disassembly process. The second fixing mechanism includes protrusions on an edge frame of the front panel, a mating piece provided on the rear panel, engaging openings provided in the mating piece, and rib-shaped plates defining stopper elements between the edge frame and the outer frame of the display module. The stopper elements prevent the protrusions from slipping out of the engaging openings by contacting the outer frame. The stopper elements are shaped to prevent interference between the stopper elements and the outer frame during cabinet assembly.
