Problems solved by technology

If the positioning of the plastic frame and the lampshade is out of alignment, in addition to the difficulty of heavy work, when the LCD panel is assembled on the backlight module, the probability of fragmentation will increase due to the inconsistent appearance and size of the backlight module.
[0005] When the probability of occurrence of the above-mentioned problems increases, the manufacturing cost will also increase relatively, so improving the above-mentioned problems is an important issue

Embodiment Construction

[0061] The invention provides a backlight module with an engaging structure. When the backlight module is combined with the plastic frame and the lampshade, the relative movement of the two in the horizontal direction and the vertical direction can be positioned to reduce the assembly error of the backlight module.

[0062] figure 1 A partial cross-sectional view of a flat panel display according to a preferred embodiment of the present invention is shown. In this embodiment, the flat panel display 100 includes a display panel 110 and a backlight module 120 , wherein the components of the backlight module 120 include a plastic frame 130 , a lampshade 140 , a light source 170 , a light guide plate 180 , an optical film 190 and a reflector 192 . The display panel 110 is located on the backlight module 120 , and the lampshade 140 is disposed on one side of the backlight module 120 . The plastic frame 130 and the lampshade 140 are engaged with each other, and the inner edge of t...

Abstract

The invention discloses a backlight module and a flat-panel display. The backlight module comprises a rubber frame, a lamp shade, a lamp source, a light guide plate and a plurality of optical films, wherein the lamp shade comprises a baffle plate and a convex component, the rubber frame is provided with a groove, and the inside of the groove is provided with a clamp component, therefore, when the rubber frame and the lamp shade are assembled, the convex component and the clamp component are mutually buckled. The backlight module disclosed by the embodiment of the invention has the advantages that the lamp shade comprises the baffle plate and the convex component, and the rubber frame is provided with the groove and a convex-component buckling part corresponding to the baffle plate, so that when the rubber frame and the lamp shade are assembled, the baffle plate and the groove are mutually buckled, thereby reducing the horizontal and vertical deviation ratios of the rubber frame. Compared with the current general assembling mode of the rubber frame and the lamp shade, the required reworking rate of the backlight module caused by different appearances and sizes of the backlight module after the rubber frame is assembled can be reduced.

Description

technical field [0001] The invention relates to a flat display, and in particular to a backlight module in the flat display. Background technique [0002] A general liquid crystal display can be roughly divided into two main objects: a display panel and a backlight module. Since the display panel is not a self-illuminating structure, it is necessary to use the backlight module to provide a sufficient and uniform light source to the liquid crystal panel to form a display with complete functions. [0003] The main parts of the backlight module include reflectors, light sources, light guide plates, diffusers, and rhombic lenses, etc., and can be divided into two structures according to the placement of the light source: direct type and side light type. The direct-lit backlight module installs the light source behind the panel and uses a diffuser to homogenize the light, which requires a large space and is mainly used in large-sized products; the side-lit backlight module hangs...
