The utility model provides a kind of backlight module with above-mentioned glue frame.
For reaching above-mentioned advantage, the utility model provides a kind of glue frame, is applied to the backlight module of liquid crystal display, and described glue frame comprises body and the photic zone of two ejection formations; Described body is frame structure, described body has the first host cavity, the second host cavity and connecting hole, described connecting hole is communicated with described the first host cavity and described the second host cavity, described the first host cavity has the first perisporium and diapire, described the second host cavity has roof and the second perisporium, described connecting hole has the connection perisporium that connects described diapire and described roof, and described photic zone covers described the first perisporium, described diapire, described connection perisporium and described roof.
In an embodiment of the present utility model, between described the first host cavity and described the second host cavity, form support portion, described connecting hole is surrounded by described support portion.
In an embodiment of the present utility model, described photic zone also covers described the second perisporium.
In an embodiment of the present utility model, described the first perisporium, described diapire, described connection perisporium, described roof and described the second perisporium form the inside surface of described body, the inside surface part of described body caves inward and forms a plurality of connecting holes, and described euphotic material is filled described connecting hole.
In an embodiment of the present utility model, described connecting hole is shoulder hole, and the larger one end of area of section is away from the inside surface of described body.
The utility model also further provides a kind of display, comprise display panels and backlight module, described backlight module comprises combination, light source, backboard, the above-mentioned glue frame of blooming piece and light guide plate, described display panels is contained in described the first host cavity, the combination of described blooming piece and light guide plate, described light source are contained in described the second host cavity, and described backboard is connected the combination with blooming piece described in support and light guide plate, described light source with described glue frame.
Compare prior art, glue frame of the present utility model and there is the liquid crystal display of this glue frame, glue frame comprises body and the photic zone of two ejection formations.On the one hand, body adopts the conventional material of existing glue frame, has the performance of the shock resistance of existing glue frame, resisting heat distortion.On the other hand, photic zone covers the inside surface of body, even if glue frame is subject to clashing into, causes that bits, transparent or translucent bits end also can allow most of light pass.Therefore,, when display panels shows complete white picture, can not form stain because of bits end, thereby improve the quality of picture.
For above-mentioned and other objects, features and advantages of the present utility model can be become apparent, preferred embodiment cited below particularly, and coordinate appended graphicly, be described in detail below.
Accompanying drawing explanation
