The working principle of the liquid crystal panel is that liquid crystal molecules are placed in two parallel glass substrates, a plurality of vertical and horizontal tiny wires are arranged between the two glass substrates, the direction of the liquid crystal molecules is controlled to change by electrifying or not, and light rays of the backlight module are refracted out to generate pictures. Since the liquid crystal panel itself does not emit light, the backlight module needs to provide a light source to display images normally, and therefore, the backlight module is one of the key structures of the liquid crystal display device.
As shown in fig. 1, the liquid crystal display device generally includes a display panel 100 'and a backlight module, the backlight module includes a back plate 1', a rubber frame 2 ', an optical film set 3', a light guide plate 4 ', and a reflective sheet 5', wherein the back plate 1 'includes a bottom plate 11' and a side plate 12 'standing on the bottom plate 11', the optical film set 3 ', the light guide plate 4', and the reflective sheet 5 'are arranged from top to bottom and are disposed in a receiving space surrounded by the bottom plate 11' and the side plate 12 ', the rubber frame 2' includes an upper frame 21 'and a side frame 22' which are vertically connected, the side frame 22 'is disposed in parallel with the side plate 12' and is located outside the side plate 12 ', and the upper frame 21' extends toward the inner side of the back plate 1 'and can be partially pressed on the upper surface of the optical film set 3'. The display panel 100 'is overlapped on the top of the upper frame 21'.

The prior art solutions to this problem are: as shown in fig. 2, the upper frame 21 'is provided with a groove-digging process at the inner side of the position of the retaining wall 23' so as to keep the thickness of the whole rubber frame 2 'approximately uniform, but this results in a reduction of the contact area between the upper frame 21' and the optical film set 3 ', affecting the fixing effect of the optical film set 3'; to prevent the occurrence of wobble noise, foam is mounted at the corner of the non-fixed side of the optical film set 3 ' near the side of the light bar (not shown in the drawing) to assist the upper frame 21 ' in fixing the optical film set 3 '. However, the foam arranged at the corners can generate corner light leakage phenomenon, which affects the taste of the display device; in addition, when the depth of the groove formed in the inner side of the upper frame 21 'is large, a thick foam is required, and when the foam is thick, the compressibility is large, the fixing effect on the optical film set 3' is also poor, the quality of the display device is affected, and a shaking noise is generated.
