Description of the Invention: [Technical Field] The present invention relates to a backlight module for a liquid crystal display, and more particularly to a design of a light source fixing frame group in the backlight module. [Prior Art] For a liquid crystal display to clearly display its face, a light source is usually provided by a backlight module disposed on the back of the liquid crystal module, and the backlight module mainly provides a light-emitting component setting by a lamp cover in the light source fixing frame group. The light guide plate of the bottom reflector is further disposed on the fixing frame, and the side end of the light guide plate is adjacent to the light-emitting element, so that the light emitted by the light-emitting element can be incident from the side end of the light guide plate, and is passed through the light guide plate. After continuous reflection, it is scattered from the surface of the board, and then is evenly scattered by the optical film to provide a uniform light source of the liquid crystal module. Regarding the structural design of the front light source fixing frame group, as shown in the seventh figure, the lampshade (6 〇) is mainly fixed on both sides of the fixing frame (70) by screws, and the lampshade (6 〇) ) The top of the lampshade part (6 work) is also fixed with tape (6 2 ) (4) on the bottom surface of the top frame edge (7 1 ) of the fixed frame (7 〇), and the lamp cover part of the lamp cover (6 〇) (6丄) And the bottom plate portion (63) holds the side end of the light guide plate (8 1 ). However, in the design of the existing light source fixed frame group, the lampshade is made of a reflective gold: material, because of the manufacturing cost of the component and the function of the lamp, so that the lampshade (60) When the side of the light guide plate (8 丄) is clamped by the lamp „ ( 6 i ) and the bottom plate portion ( 6 3 ), the light-emitting element (80) in the lamp cover (6 〇) enters the light from the side of the light guide plate (81). When the light guide plate (8 1 ) travels, it will cause the reflected light passing through the light guide (8 1 ) end = the upper liquid crystal mode & (9 formed bright line, causing) b曰颂 unpleasant panel The problem of unevenness in light and shade, as a result, most of the current manufacturers have printed a dimming layer on the underside of the lampshade portion (6) of the wide lampshade (60) as a process for subscribing to the bright line, however, at the lamp $ (6 〇) ) The reduction of the first layer in China and India will lead to an increase in material costs 'reduced profits, and the lamp $ (6 ◦)
