Definitions
- Liquid crystal display has many advantages such as thin body, power saving, and no radiation, and has been widely used.
- Most of the liquid crystal display devices on the market are backlight type liquid crystal display devices, which include a liquid crystal display panel and a backlight module.
- the working principle of the liquid crystal display panel is to place liquid crystal molecules in two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates, and the liquid crystal molecules are controlled to change direction by energizing or not, and the light of the backlight module is changed. Refracted to produce a picture. Since the liquid crystal display panel itself does not emit light, the light source provided by the backlight module is required to display the image normally. Therefore, the backlight module becomes one of the key components of the liquid crystal display device.
- the existing backlight module is provided with a plastic frame for supporting the liquid crystal display panel and shielding the light leakage.
- the plastic frame is also designed into a plastic frame (as shown in FIG. 1 ), and the split plastic frame includes several
- the corner piece 200 is disposed separately, corresponding to the side plate 102 on which the back plate 100 is mounted, and the cross-section of the corner piece 200 is in a side-down T shape.
- Split-type plastic frame for example, four-corner plastic frame
- the backboard includes a bottom plate and a plurality of side plates connected to the bottom plate, and the corner members are respectively disposed on the side plates of the back plate.
- the corner pieces are respectively disposed at joints between the side plates.
- the corner pieces are attached to the side plates of the backboard by gluing or screwing.
- the support surface is a corner piece away from the upper surface of the optical film set.
- the fixing portion is a protrusion protruding from the corner piece near the lower surface of the optical film group, and the engaging portion is a matching hole provided on the optical film group.
- the backlight module of the present invention increases the support area of the liquid crystal display panel by using the upper surface of the split type plastic frame as the support surface of the liquid crystal display panel, thereby improving the stability of the support, and It effectively prevents the occurrence of light leakage, ensures the brightness of the backlight module, and improves the optical grade.
- the backboard 2 includes a bottom plate 22 and a plurality of side plates 24 connected to the bottom plate 22.
- the corner pieces 82 are respectively fixed to the side plates 24 of the backboard 2 by gluing or screwing.
- the corner pieces 82 are respectively disposed at the joints between the side plates 24.
- the number of the side plates 24 is four, and the number of the corner pieces 82 corresponds to four.
- the corner piece 82 is disposed adjacent to the optical film set 6 and has a fixing portion 824.
- the optical film group 6 is provided with a matching portion 62 corresponding to the fixing portion 824.
- the optical film group 6 is fixed by the cooperation of the fixing portion 824 and the engaging portion 62.
- the fixing portion 824 is a protrusion protruding from the corner member 82 on the lower surface 826 of the optical film group 6
- the engaging portion 62 is a matching hole provided on the optical film group 6 .
- the protrusion is engaged in the matching hole, and the optical film group 6 is further fixed.
- the protrusion is located at a joint of the first and second connecting members 84, 86, and has a cylindrical shape
- the matching hole is a circular through hole.
