Description
Technical field
The utility model relates to display technology field, especially relates to a kind of backlight module.
Background technology
Due to liquid crystal display have that volume is little, lightweight, the advantage such as power saving, radiation are low, be easy to carry about with one, progressively replace negative electrode pick-up tube display, be widely used in various electric consumers, as notebook computer, mobile phone, mobile unit etc.Liquid crystal indicator mainly comprises liquid crystal panel and backlight module, and liquid crystal panel passes through together with adhered by double sided plaster with backlight module.In production and use procedure, when liquid crystal panel or backlight module are subject to breakage, usually need to separate liquid crystal panel and backlight module to place under repair to impaired part or to change.
Traditional design, bottom backlight, FPC directly pastes at light guide plate and glue frame, fixes above with shading glue, if shading gummed paper and FPC gummed paper viscosity deficiency will tilt in hot and humid environment, cause the bad of quick-fried lamp and light leak bottom backlight, affect display effect.
Utility model content
The technical problem that the utility model solves is: solve module shading glue and FPC gummed paper under hot and humid environment and tilt the problem occurring quick-fried lamp or light leak bottom backlight.
A kind of backlight module is the utility model proposes for solving the problem, comprise backboard, glue frame, described glue frame is positioned on described backboard, described backboard is provided with light guide plate, FPC, shading gummed paper, LCD glass, described FPC sticks on described light guide plate, the top of described FPC is provided with described glue frame, and described glue frame thickness is greater than described FPC; Described shading gummed paper fits on described glue frame and FPC, and described shading gummed paper is provided with cushion block, and described LCD glass is located on described cushion block, described LCD glass, forms dead slot between cushion block and shading gummed paper, is filled with fixture in described dead slot.
The further preferred version that the utility model proposes, described fixture is elastic foam.
The further preferred version that the utility model proposes, described shading gummed paper thickness is 0.055mm.
The further preferred version that the utility model proposes, the viscosity of described light-shielding sheet is 14.8N/25mm.
The further preferred version that the utility model proposes, described FPC is sticked on described light guide plate by FPC high temperature double faced adhesive tape.
A kind of backlight module that the utility model proposes has following beneficial effect: between FPC and LCD glass, increase elastic foam, first can push down FPC, make it should not tilt under hot and humid environment, eliminate the quick-fried lamp in bottom or the phenomenon of light leak, second also can improve client breaks due to LCD glass Hanging sectionally when doing and falling and wait and test.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is the side view of display module of the present utility model;
Fig. 2 is the schematic enlarged-scale view of display module of the present utility model;
Wherein, 1-backboard, 2-glue frame, 3-light guide plate, 4-FPC, 5-shading gummed paper, 6-LCD glass, 7-cushion block, 8-elastic foam.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
In conjunction with Fig. 1-2, the utility model proposes a kind of backlight module, comprise backboard 1, glue frame 2, described glue frame 2 is positioned on described backboard 1, described backboard is provided with light guide plate 3, FPC 4, shading gummed paper 5, LCD glass 6, described FPC 4 sticks on described light guide plate 3, and the top of described FPC 4 is provided with described glue frame 2, and described glue frame 2 thickness is greater than described FPC 4; Described shading gummed paper 5 fits on described glue frame 2 and FPC 4, and the gap between FPC 4 and glue frame 2 covers by shading gummed paper 5, prevents light leak.
Described shading gummed paper 5 is provided with cushion block 7, described LCD glass 6 is located on described cushion block 7, described LCD glass 6, between cushion block 7 and shading gummed paper 5, form dead slot, be filled with fixture in described dead slot, wherein, described fixture is elastic foam 8, elastic foam 8 can be full by the fill gaps between LCD glass 6 and FPC, and the light through shading gummed paper 5 can cover by elastic foam further, and anti-fall test time, LCD glass 6 rear portion is filled, increases steadiness.
The further preferred version that the utility model proposes, described shading gummed paper 5 thickness is 0.055mm, and viscosity is 14.8N/25mm, and thickness is that shading gummed paper 5 obscurity of 0.055mm is high, and almost light does not spill.
The further preferred version that the utility model proposes, described FPC 4 sticks on described light guide plate 3 by FPC high temperature double faced adhesive tape, and FPC high temperature double faced adhesive tape can be high temperature resistant, prevents hot and humid environment from FPC is tilted.
To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
