Description of the Invention: [Technical Field] The present invention relates to a frame device, and more particularly to a frame device applied to a liquid crystal display module. [Prior Art] With the advancement of display technology, thin film transistor liquid crystal display (TFT-LCD) is light, thin, low-reflection, and small in size compared with conventional CRT displays. Taking advantage of space, it has become the main product of the display market. The application level of the liquid crystal display module is quite extensive, and the LCD TV, the desktop liquid crystal display and the notebook computer screen are all products with a liquid crystal display module. Please refer to FIG. 1 , which is a cross-sectional view of a conventional liquid crystal display module. As shown in FIG. 1 , the liquid crystal display module 1 includes at least an outer frame 11 , a plastic frame 12 , a liquid crystal panel 13 , a backlight module and a screw 15 . The outer frame 11 is covered over the winch frame 12, and the side wall of the plastic frame a is located inside the side wall of the outer frame 11. Thereby, the outer frame U and the plastic frame 12 form a accommodating jade, and the liquid crystal panel 13 and the backlight module μ are disposed in the accommodating space. The backing wire set 14 includes at least elements such as a light source (not shown), a light guide plate 141, and an optical film 142. In order to effectively fix the positions of the liquid crystal panel i 3 and the backlight module i 4 , the outer frame 11 and the structure of the win frame 12 are respectively adjacent to and support the liquid crystal panel i3 and the back light module 14 . Then, the side frame 11 and the side wall of the plastic frame 12 are locked by screws 15 to complete the assembly of the liquid crystal display module 1. It is to be noted that the uppermost layer of the liquid crystal panel 13 is a glass plate 133, and the glass plate 133 is adjacent to the bottom plate of the outer frame 11. However, as the liquid crystal display module becomes thinner and lighter, the thickness of the glass plate 133 is also made thinner and thinner, and the rigidity of the glass plate is also relatively poor. Therefore, after the outer frame 11 and the truss frame 12 are assembled and fixed by the screws 15, the liquid crystal layer gap in the liquid crystal panel 13 is easily changed by the structure of the outer frame 11 due to assembly deformation or mechanism interference. Further, a ripple phenomenon occurs in the display surface near the outer frame pressing portion 11a. In addition to the fact that the outer frame 11 directly presses the liquid crystal panel 13, the corrugated phenomenon may be pressed by the frame 12 to the backlight module i4 (please refer to the frame pressing area 12a in FIG. 1) to make the backlight module 14 The liquid crystal panel 13 is pushed, and the liquid crystal panel 13 is pressed by the outer frame 11. It is easy to cause the user's visual discomfort to show the corrugated phenomenon of the kneading surface. Therefore, the product specification is not allowed to be missing. The trick is how to improve the corrugation caused by the compression of frames such as frames and frames, which is a problem that must be solved by current technology.
