Along with the fast development of Display Technique, liquid crystal indicator contains much information with its low-voltage driving, display, be easy to colorize, long-life, the advantage such as radiationless obtain extensive use.Liquid crystal itself can not be luminous, and need backlight module to provide light source, backlight module is mainly divided into down straight aphototropism mode set and side entrance back module two kinds according to distribution of light sources position difference.Down straight aphototropism mode set is arranged on below liquid crystal panel by light source, and direct forming surface light source is supplied to liquid crystal panel.Side entrance back module is that light source is arranged on liquid crystal panel side, and line source is transformed to area source via light guide plate and is supplied to liquid crystal panel by light.Fig. 1 is the exploded view of prior art side entrance back module, and side entrance back module comprises backboard 10, is placed in the light source 20 of backboard 10 side, is fixed on the reflector plate 30 on backboard 10, light guide plate 40, optical diaphragm group 50 and glue frame 60 successively.Fig. 2 is the profile of prior art side entrance back module, glue frame 60 is placed on light guide plate 40 to limit light guide plate 40 free degree in the vertical direction, because glue frame 60 footprint area is larger, the light of light guide plate 40 surrounding can be covered, make again liquid crystal indicator have larger frame size D simultaneously, cannot realize narrow frame, Consumer's Experience sense is lower.
Utility model content
For solving the problem, the utility model provides a kind of backlight module, by arranging groove structure in light guide plate non-light source side, glue frame arranges the first projective structure matched, light guide plate is fixed on glue frame, the size of backlight luminescence district to frame can be reduced, reach the purpose of design of narrow frame.
The utility model provides a kind of backlight module, comprise backboard, be placed in the light guide plate on backboard, be placed in the light source of light guide plate side, for the glue frame of lightguide plate fixing and the optical diaphragm group that is placed on glue frame, the side that wherein light guide plate is adjacent with light source is called incident side, the side adjacent and relative with incident side is all called non-light source side, be provided with through groove structure in the non-light source side direction of light guide plate, be provided with the first projective structure inside glue frame and be placed in described groove structure.Described glue frame is split type glue frame, and comprise glue moulding and U-shaped glue frame, the first described projective structure is positioned at inside U-shaped glue frame.The top end face of described glue frame is provided with at least one second projective structure for fixed optics diaphragm group.The incident side two ends of described light guide plate are provided with perforate and are convenient to the fixing of glue moulding.
The utility model provides a kind of backlight module, by arranging groove structure in light guide plate non-light source side, glue frame arranging the first projective structure matched with groove structure, light guide plate is fixed on glue frame, the size of backlight luminescence district to frame can be reduced, reach the purpose of design of narrow frame.
