technical field

The invention relates to a frame structure of a liquid crystal display, in particular to an improvement of the frame structure of a liquid crystal display with an elastic locking mechanism.

Background technique

A liquid crystal display (LCD) is mainly composed of a liquid crystal panel and a backlight module (backlight). When assembling, in order to avoid direct contact between the liquid crystal panel and the backlight module, metal frames are usually installed on the edges of the liquid crystal panel and the backlight module, and each metal frame is processed to form a mechanism that can be buckled with each other. The two can be fastened and fixed by the fixing mechanism of the metal frame. Therefore, whether the design of the fixing mechanism on the metal frame is convenient for panel assembly and disassembly will seriously affect the finished product yield and production speed.

The fixing mechanisms traditionally applied to the outer frame of liquid crystal displays can be roughly divided into two types: bending type and buckling type. 1a and 1b are schematic diagrams of a liquid crystal display frame with a bending fixing mechanism 10 . Please refer to Fig. 1a, on the edge of the liquid crystal panel frame 12, there are fasteners 14 protruding and sinking into the vertical surface of the frame, respectively inserting the fasteners into the slots on the frame of the backlight module and bending them when assembling. achieve a fixed purpose. FIG. 1 b is a partially enlarged view of the bending fixing mechanism 10 .

2a and 2b are a schematic diagram of a liquid crystal display frame 20 with a buckle-type fixing mechanism and a cross-sectional view of the buckle-type fixing mechanism. Referring to FIG. 2 , an opening 24 is formed on the vertical edge of the liquid crystal panel frame 22 , and a protruding structure 28 is formed on the vertical edge of the backlight module frame 26 at the corresponding position below. When the liquid crystal panel 30 is assembled with the backlight module, the protruding structure 28 is snapped into the opening 24 of the outer frame 22 of the liquid crystal panel, so that the two can be fixed to each other. The biggest disadvantage of the above two fixing methods is that the fixing device is not an elastic structure, which makes the metal frame of the liquid crystal display easily deformed or scratched during assembly and disassembly. The panel or the backlight module body is damaged.
