Description
Technical field
This utility model belongs to Display Technique field, is specifically related to a kind of guide-lighting board fixer.
Background technology
In recent years, most mobile phone, notebook computer, desktop computer, digital still camera and scialyscope are all using liquid crystal display as display screen.But, owing to liquid crystal itself is not luminous, so a backlight module must be provided below liquid crystal display, the point source or the line sources that provide backlight are changed into area source, with well-off brightness.Wherein, light guide plate, as the important feature of backlight module, is the critical elements affecting light efficiency, and its major function is in that to guide radiation direction, to control brightness uniformity.In recent years, owing to gradually towards slimming, sizing LCD evolution, causing that light guide plate is more and more thinner.Because light guide plate declines, so its heat absorption expansion characteristics highlights gradually, light guide plate is fixed at the beginning, and after heat absorption, it will expand, and so can deform because of extruding, thus largely effecting on the quality of light.
Summary of the invention
It is an object of the invention to: light guide plate expands because of heat absorption to provide one can solve the problem that, the guide-lighting board fixer of deformation effect light quality because of extruding.
This utility model solves its technical problem and be the technical scheme is that
A kind of guide-lighting board fixer, including backboard, its described backboard is provided with housing, and described housing is looped around described backboard periphery and arranges；The cavity placing light guide plate is formed between described backboard and described housing；
Described housing includes lower edge frame and exterior wall；Described lower edge frame is arranged on described backboard bottom periphery；Described exterior wall is looped around described backboard surrounding and is vertically arranged with described lower edge frame；Described inner side of outer wall is provided with multiple Buffer Unit, and described Buffer Unit includes buffer spring and spring mounting post.
Also including front frame, described front frame is arranged on described backboard top, and for described light guide plate is fixed on described backboard, described front frame includes upper limb frame and is socketed in the exterior wall frame outside described exterior wall.
Described spring mounting post is cylinder, and described spring mounting post and described exterior wall are vertically arranged, and described spring housing is connected in described spring mounting post.
Described exterior wall frame lower inside is provided with triangle convex, is provided with mean for the groove that described triangle convex embeds outside described exterior wall.
Upper limb frame bottom is provided with rubber fixture.
Described exterior wall both sides are provided with the cavity for mounted LED lamp.
Described backboard is plastics or metal material.
The present invention highlights and useful having the technical effect that compared to existing technology
The guide-lighting board fixer of the present invention, the side of light guide plate is the Buffer Unit rested upon on the inner surface of exterior wall and is fixed, while lightguide plate fixing, the elastomeric material of Buffer Unit is supplied to one cushion space of light guide plate, to prevent light guide plate crimp because of expansion, and maintain the performance of light guide plate impact resisting vibrating, solve light guide plate and expand after heat absorption, cause extruding and the problem that deforms.
