Abstract
The utility model discloses a backlight unit's socket structure, including LED lamp, light guide plate, FPC and FPC double faced adhesive tape, the LED lamp set up in one side of light guide plate, and its bottom is passed through the FPC double faced adhesive tape with FPC connects, the upper portion of LED lamp higher in the light guide plate, just the upper portion of LED lamp sets up the PET membrane, the PET membrane with form the socket between the light guide plate. The utility model provides a backlight unit's socket structure, through with the light guide plate with form the socket between the PET membrane, the socket has certain radian, and the LED lamp is luminous, can follow the socket and distribute, in the socket, with the light struck to the light guide plate for the light of the play that the light guide plate gived off is even, the permanent magnet rotor has advantages of simple structure, stable performance, and long service lifetime.
Description
Technical field
The utility model relates to technical field of liquid crystal display, particularly relates to a kind of socket structure of backlight module.
Background technology
Backlight module is one of key part and component of panel of LCD, and because liquid crystal itself is not luminous, backlight module major function is the light source improving enough brightness and be evenly distributed, and makes it normally show.
In existing backlight module, most FPC is attached to glue frame and light guide plate front by FPC double faced adhesive tape, FPC glue is black and white two sides, black flour is close to light guide plate and is prevented light from overflowing from FPC glue, and fine flour is reflective can improve light source utilization rate, thus ensures socket effect while effectively utilizing light source.The existing majority in light guide plate socket place does wedge shape, and FPC glue cannot compress light guide plate and cause light to cause socket brighter from FPC glue spilling, comparatively dark between lamp, bright dark inequality.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of socket structure of backlight module.
The technical solution of the utility model is as follows: the utility model provides a kind of socket structure of backlight module, comprise LED, light guide plate, FPC and FPC double faced adhesive tape, described LED is arranged at the side of described light guide plate, and be connected with described FPC by described FPC double faced adhesive tape bottom it, the top of described LED is comparatively higher than described light guide plate, and the top of described LED arranges PET film, between described PET film and described light guide plate, form socket.
The utility model is preferred, and described PET film is white PET film, has radian in the middle part of the described socket formed between itself and described light guide plate, and the number of degrees of described radian are between 135 °-175 °.
The utility model is preferred, and the number of degrees of described radian are 165 °.
The utility model is preferred, and the bottom of described FPC is provided with chase, and one end of described chase is arranged in the glue frame meat wall of described LED opposite side setting, and the opposite side of described glue frame meat wall is provided with member slot.
The utility model is preferred, and the top of described PET film is provided with shading glue, avoids light leakage.
The beneficial effects of the utility model are as follows:
Adopt such scheme, the utility model provides a kind of socket structure of backlight module, by forming socket by between light guide plate and described PET film, socket has certain radian, LED is luminous, can distribute, by socket from socket, light shine in light guide plate, the uniform light gone out that light guide plate is distributed; The utility model has that structure is simple, stable performance and serviceable life longer advantage.
Accompanying drawing explanation
Fig. 1 is the cut-open view of the socket structure of backlight module described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Refer to Fig. 1, the utility model provides a kind of socket structure of backlight module, comprise LED 1, light guide plate 2, FPC3 and FPC double faced adhesive tape 5, LED 1 is arranged at the side of light guide plate 2, and be connected with FP3C by FPC double faced adhesive tape 5 bottom it, the top of LED 1 is comparatively higher than light guide plate 2, and the top of LED 1 arranges PET film 4, forms socket 11 between PET film 4 and light guide plate 2.
As shown in Figure 1, PET film 4 is white PET film, in the middle part of the socket 11 formed between itself and light guide plate 2, there is radian 10, the number of degrees of radian 10 are 165 °, the bottom of FPC3 is provided with chase 8, and one end of chase 8 is arranged in the glue frame meat wall 9 of LED 1 opposite side setting, and the opposite side of glue frame meat wall 9 is provided with member slot 7, the top of PET film 4 is provided with shading glue 6, avoids light leakage.
Principle of work of the present utility model is as follows:
The utility model is by forming socket 11 between light guide plate 2 and PET film 4, and the middle part of socket 11 arranges radian, the number of degrees are 165 °, the shape that light guide plate 2 and PET film 4 adapt to socket 11 is arranged, and when LED 1 sends light, conducts in light guide plate 2 by socket 11 by light, light guide plate 2 is made to give out uniform light, shading glue 6 is set on the other hand, ensures that the light in socket can not be revealed, cause the light in light guide plate 2 to have dark luminous point.
In sum, adopt such scheme, the utility model provides a kind of socket structure of backlight module, by forming socket by between light guide plate and described PET film, socket has certain radian, and LED is luminous, can distribute from socket, by in socket, light shine in light guide plate, the uniform light gone out that light guide plate is distributed; The utility model has that structure is simple, stable performance and serviceable life longer advantage.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
