In this liquid crystal display, the panel module 20 is fixed to the rear cover 102 of the casing 10, and it is mainly locked by using screws 30 to penetrate the screw holes 103 and 201 on both sides. " (that is, the narrower the frame thickness d of the liquid crystal display, the better), but for the assembly process, after the operator finishes locking the screws facing his side, he also needs to rotate the panel module 20 so that the other side faces himself. Lock again, so the operability of this structural design is relatively poor, is unfavorable for the raising of production efficiency.

Also disclosed in this U.S. patent is another liquid crystal display. As shown in FIG. Complete all screws, workability is obviously better, but, in order to set the screw holes 42 on the front, the thickness D of the frame 41 must be increased, so this structural design does not meet the current "narrow frame" requirements.

In addition to LCD monitors, the same problem can also occur on other flat panel monitors.
