Description

Fixed structure of a liquid crystal panel

technical field

The utility model relates to a fixing structure, in particular to a fixing structure of a liquid crystal panel used in a flat panel display.

Background technique

In recent years, traditional cathode ray tube displays (CRT, Cathode Ray Tube) have been gradually replaced by flat-panel displays. The main reason is that the amount of radiation emitted by flat-panel displays is much smaller than that of CRT displays. Manufacturing costs have dropped dramatically, which is why flat-panel displays have become mainstream in the TV or computer screen market.

Generally speaking, a flat panel display includes a liquid crystal panel, and other mechanical structures are used to fix the liquid crystal panel. Referring to FIG. 1 , FIG. 1 is a schematic diagram of a fixing structure of a liquid crystal panel in the prior art. As shown in FIG. 1 , the liquid crystal panel fixing structure 1 includes a front frame 11 , a liquid crystal panel 12 , a metal plate 13 , a stand 14 and a rear shell 15 . The metal plate 13 is combined with the front frame 11 to clamp and fix the liquid crystal panel 12. The fixing method is to use a plurality of screws 131 to pass through the four sides of the metal plate 13, and the liquid crystal panel 12 Lock on the front frame 11. In addition to fixing the liquid crystal panel 12, the metal plate 13 also has the function of preventing electromagnetic interference, so as to prevent the sudden external electromagnetic waves from affecting or disturbing the control circuit of the flat-panel display (not shown). The rear case 15 is combined with the front frame 11 , and the front frame 11 and the rear case 15 will cover the metal plate 13 and the liquid crystal panel 12 after the combination. The stand 14 is fixed on the metal plate 13 by screws 141, and the mechanical strength of the metal plate 13 combined with the stand 14 is used to support the weight of the front frame 11, the liquid crystal panel 12, the metal plate 13 and the rear shell 15 .

However, the above liquid crystal panel fixing structure 1 uses a metal plate 13 with the same area as the liquid crystal panel 12 to fix the liquid crystal panel 12, which not only cannot reduce the weight of the flat panel display, but also requires a lot of metal material cost. In addition, in order to fix the heavy liquid crystal panel 12 , at least eight screws 131 need to be locked on the four sides of the metal plate 13 , which further increases the man-hours of assembly. In addition, as mentioned above, the fixing structure 1 of the liquid crystal panel is likely to generate a gap between the contact between the liquid crystal panel 12 and the front frame 11 due to the positioning error of the screw 131 and the front frame 11 . Therefore, how to reduce the weight of the flat-panel display, save the material cost of the metal plate 13 and the time cost of assembly, and eliminate the gap between the liquid crystal panel 12 and the front frame 11 are issues worthy of consideration by those skilled in the art.
