Abstract
The utility model discloses light guide plate and the adhesive frame structure of a kind of backlight assembly, including light guide plate, glue frame, reflector plate；Described reflector plate is fitted in the bottom surface of light guide plate, light guide plate is fixed in glue frame together with reflector plate thereon of fitting, having gap between the lateral surface and the medial surface of glue frame of light guide plate, the lateral surface of light guide plate all carries out mirror finish process with the medial surface of glue frame.The lateral surface of the light guide plate after injection being completed due to this utility model, the medial surface of glue frame do mirror finish respectively and process, make guide-lighting machine lateral surface medial surface smooth, glue frame smooth, again light guide plate, glue frame are assembled in backlight module, this structure can substantially increase the utilization rate of light, improves the brightness of screen.
Description
Technical field
This utility model relates to mobile phone backlight module technical field, particularly relates to light guide plate and the glue of a kind of backlight assembly
Mount structure.
Background technology
As it is shown in figure 1, the light guide plate 1 ' in original backlight module and supporting glue frame 2 ', it is molded into by injection machine respectively
Type, its injection mold side used is general-purpose grinder processing, therefore the most coarse, the light guide plate 1 ' that is therefore molded by and supporting
Glue frame 2 ' side is rougher, and because the screen intensity of present mobile phone requires more and more higher, backlight module manufacturer needs thousand sides hundred
The method finding out raising screen intensity of meter, as in figure 2 it is shown, in the case of LED light source brightness is identical, due to original leaded light
Plate 1 ' side is rougher, after causing light to arrive glue frame 2 ' side, it is impossible to be reflected back light guide plate 1 ' internal, at coarse side
Can produce loss, luminous energy slatterning in vain, the brightness making screen is inadequate.
In view of this, the design people designs not attain to improve led for light guide plate and the adhesive frame structure of original backlight module
The many disappearances caused deeply are conceived with inconvenience, and actively research improvement has a fling at and develops and design this utility model.
Summary of the invention
The purpose of this utility model is to provide the light guide plate of a kind of backlight assembly improving screen intensity and glue frame knot
Structure.
For achieving the above object, technical solution of the present utility model is:
This utility model is light guide plate and the adhesive frame structure of a kind of backlight assembly, including light guide plate, glue frame, reflector plate；Institute
The reflector plate stated is fitted in the bottom surface of light guide plate, and light guide plate is fixed in glue frame, at leaded light together with reflector plate thereon of fitting
Having gap between lateral surface and the medial surface of glue frame of plate, the lateral surface of light guide plate all carries out minute surface throwing with the medial surface of glue frame
Optical processing.
Described light guide plate end face is coated with shading glue with the junction of glue frame.
After using such scheme, the lateral surface of the light guide plate after injection being completed due to this utility model, the inner side of glue frame
Face is done mirror finish respectively and is processed so that guide-lighting machine lateral surface medial surface smooth, glue frame is smooth, then by light guide plate, glue frame group
Installing in backlight module, this structure can substantially increase the utilization rate of light, improves the brightness of screen.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the partial sectional view commonly using light guide plate and adhesive frame structure；
Fig. 2 is the light loss schematic diagram commonly using light guide plate and adhesive frame structure；
Fig. 3 is partial sectional view of the present utility model；
Fig. 4 is the schematic diagram of this utility model light line reflection.
Detailed description of the invention
As it is shown on figure 3, this utility model is light guide plate and the adhesive frame structure of a kind of backlight assembly, including light guide plate 1, glue frame
2, reflector plate 3.
Described reflector plate 3 is fitted in the bottom surface of light guide plate 1, and light guide plate 1 is fixed on together with reflector plate 3 thereon of fitting
In glue frame 2, it is coated with shading glue 4 in the junction of light guide plate 1 end face Yu glue frame 2.The lateral surface 11 of described light guide plate 1 and glue
Having gap between the medial surface 21 of frame 2, the lateral surface 11 of light guide plate 1 is all carried out at mirror finish with the medial surface 21 of glue frame 2
Reason, has high fineness.
Operation principle of the present utility model:
As shown in Figure 3, Figure 4, the medial surface 21 of the lateral surface 11 of light guide plate 1, glue frame 2 is carried out mirror finish process respectively
After, when light is through the lateral surface 11 of light guide plate 1, there is some light to be reflected back from light guide plate 1 lateral surface 11 after polishing
Light guide plate 1 is internal, after remainder light continues to be irradiated to glue frame 2 medial surface 21, then glue frame 2 medial surface 21 meeting through polishing
Remaining light is also reflected back light guide plate 1 internal, thus, substantially increase the utilization rate of light, improve the brightness of screen.
Emphasis of the present utility model is that lateral surface and the medial surface of glue frame of the light guide plate using best bright finish.
The above, only this utility model preferred embodiment, therefore can not limit what this utility model was implemented with this
Scope, the equivalence change i.e. made according to this utility model claim and description and modification, all should still belong to this reality
In the range of containing with new patent.
Claims (2)
