Abstract
The utility model relates to a backlight module frame seat having optical membrane positioning function. The frame seat is formed by a bendable positioning wing panel molded outside a positioning concave portion on a dike wall portion, fixing portions are formed on two corresponding lateral walls of the positioning concave portion. Therefore, when the optical membrane is embedded into the frame seat, a convex portion at lateral edge of the optical membrane extends into a positioning concave portion at bottom surface of the positioning concave portion, namely the bendable positioning wing panel abuts against the convex portion at lateral edge of the optical membrane, and is fixed by fixing portions, no adhesive belts are needed for adhering and fixing. Therefore, the assembly operation for placing the optical membrane set into the frame seat has great convenience, which is capable of effectively reducing working time, reducing application of adhesive belts, and effectively lowering manufacturing cost of the backlight module.

Backlight module as shown in Figure 7, for blooming piece 40 firmly is positioned in the skeleton frame 30, the side of blooming piece 40 protrudes out at least one protuberance 41, the corresponding location with protuberance 41 forms recesses on the embankment wall of skeleton frame 30, protuberance 41 can be stretched into wherein in contraposition, with adhesive tape 50 this protuberance 41 is sticked together on the embankment wall that is fixed in skeleton frame 30 again, reach blooming piece 40 is fixed on the skeleton frame 30.
Aforesaid use adhesive tape is fixed on mode of operation on the skeleton frame with blooming piece, must be according to the protuberance position of blooming piece, re-use on the protuberance that adhesive tape is attached at skeleton frame and blooming piece accurately, so in the process of operation, have time-consuming shortcoming of taking a lot of work.Simultaneously, because must use the adhesive tape that adds, and the high shortcoming of cost is arranged.
Summary of the invention
The object of the present invention is to provide a kind of backlight module skeleton frame of tool blooming piece positioning function, time-consuming the taking a lot of work and shortcoming such as cost height that is used for improving present use adhesive tape fixed optics diaphragm.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of backlight module skeleton frame of tool blooming piece positioning function, it is characterized in that: its periphery has embankment wall portion, at least be provided with a location indentations in the described embankment wall portion, described location indentations bottom surface forms the contraposition recess, protrude out a bent positioning tabs outwardly from described location indentations outer side edges, be formed with fixed part on two corresponding sidewalls of described location indentations.
Because the employing of technique scheme, the utility model compared with prior art has the following advantages:
Embankment wall portion with skeleton frame forms positioning tabs with respect to the location indentations outside, cooperate the fixed part design on the location indentations sidewall, when blooming piece is inserted skeleton frame, after blooming piece side protuberance stretches into location indentations, be that bent this positioning tabs compresses and fixes this blooming piece side protuberance, need not be sticked together fixingly that the assembling process that optical diaphragm group is arranged in this skeleton frame has splendid convenience with adhesive tape, can effectively shorten man-hour, and the material cost of adhesive tape capable of reducing using.
