In order to solve above-mentioned technical matters, the utility model proposes a kind of installation position structure of LCD sealing mouth of backlight frame, comprise frame, on frame, be provided with the sealing mouth groove that is used for ccontaining LCD sealing mouth, described sealing mouth groove ecto-entad is along sealing mouth groove depth direction, dwindle step by step in the staircase structure mode, the interior cell body of sealing mouth groove keeps and the corresponding size of LCD sealing mouth.
Preferably: described staircase structure mode comprises the step of classification, in described sealing mouth groove a step is arranged, and is water jacket on this step, and this step is inside groove down.Because the degree of depth of sealing mouth groove itself is not very big, can meet the demands basically so sealing mouth groove is divided into one-level staircase structure.Can suitably increase the ladder progression of sealing mouth groove for comparatively dark sealing mouth groove.This step can relax and simplify the effect of the degree of depth for dark narrower groove position.
Preferably: the height of described water jacket and inside groove is identical.Identical the judging with sensation of operating personnel that help of the height of water jacket and inside groove pasted black and white glue.
Preferably: the width of described inside groove account for described water jacket width 1/3rd.Identical the judging with sensation of operating personnel that help of the height of water jacket and inside groove pasted black and white glue.
Preferably: be pasted with in the described sealing mouth groove and the corresponding to stepped black and white glue oral area of the staircase structure of sealing mouth groove position, this black and white glue oral area position and black and white glue main body fuse.
The beneficial effects of the utility model:
The slot deep groove structure of sealing mouth groove compared to existing technology, the utility model is designed to staircase structure with sealing mouth groove, its notch becomes wideer, but interior groove keeps and the corresponding size of LCD sealing mouth, such structure neither can influence LCD sealing mouth to be inserted in this sealing mouth groove, and the stickup of very convenient black and white glue in sealing mouth groove.Because the notch of sealing mouth groove has been widened, the position that causes black and white glue to insert sealing mouth groove also will increase sub-fraction accordingly, will increase the area of black and white glue like this, increases the adhesion of black and white glue.Notch owing to sealing mouth groove has broadened simultaneously, black and white glue is aimed at the also easier judgement of behavior of sealing mouth groove, so just can improve the efficient of pasting black and white glue, does not also influence the ccontaining problem of LCD sealing mouth simultaneously, and almost do not increase cost, the sticking effect of black and white glue also significantly improves.
