Along with the frivolous narrow development trend of current LCD TV, the border width of liquid crystal module also requires more and more narrow, but, because the width of the front edge 121 of described front chase 120 is narrow, on described lamp bar 160, the visible area of the described liquid crystal panel 110 of the light-emitting area of LED lamp distance is just very near, when adopting silica gel strip 170 to coordinate described iron backboard 140 to compress described light guide plate 150, if described lamp bar 160, iron backboard 140 with and upper heat radiator moulding and/or assembling have certain deviation, the deflection that described silica gel strip 170 is less is not enough to again overcome this departure, just easily cause light inlet side or the situation heavy or that gently occur leaking lamp of liquid crystal module.
In addition, at the non-light incidence side of liquid crystal module, the pressure being applied on described light guide plate 150 edges by described silica gel strip 170 also can cause the part of this light guide plate 150 to produce certain distortion, and occurs the phenomenon of whiting printing opacity (pressing white); Shown in Fig. 2, Fig. 2 is that the utility model liquid crystal module middle frame support used and iron backboard are in the front side at spacing place partial perspective view, especially the spacing assembly structure place with described iron backboard 140 at described middle frame support 130, on sidewall due to described middle frame support 130, have the hole slot 133 of hollow out, so also show more obviously in the white phenomenon of pressure at these hole slot 133 places.
Therefore, prior art still haves much room for improvement and develops.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of leakproof lamp and presses white liquid crystal module, can prevent that its light inlet side from occurring leaking lamp and avoiding light guide plate to occur the phenomenon of whiting printing opacity.
Meanwhile, the utility model also provides a kind of LCD TV, and its liquid crystal module used can prevent from occurring leaking lamp and avoiding light guide plate to occur the phenomenon of whiting printing opacity in light inlet side.
The technical solution of the utility model is as follows: a kind of leakproof lamp and the white liquid crystal module of pressure, comprise liquid crystal panel, light guide plate, lamp bar, front chase, middle frame support and iron backboard, described middle frame support and iron backboard are all sleeved on the inner side of described front chase, the edge of described liquid crystal panel is pressed between the front edge of described front chase and the interior edge of described middle frame support, the interior frame of described middle frame support extends internally and is useful on the scrap (bridge) that compresses described light guide plate edge, described light guide plate is pressed between described scrap (bridge) and described iron backboard, described lamp bar is positioned at the side of described light guide plate, wherein: between described scrap (bridge) and described light guide plate, be provided with foam bar.
Described leakproof lamp and the white liquid crystal module of pressure, wherein: described scrap (bridge) is provided with for keeping off the first convex tendon at described foam bar inner side edge on the surface of described light guide plate one side.
Described leakproof lamp and the white liquid crystal module of pressure, wherein: described scrap (bridge) is provided with for keeping off the second convex tendon in described foam bar outer side edges on the surface of described light guide plate one side.
Described leakproof lamp and the white liquid crystal module of pressure, wherein: described foam bar is positioned at a side of described lamp bar.
A LCD TV, comprises liquid crystal module, wherein: described liquid crystal module is set to the leakproof lamp described in above-mentioned middle any one and presses white liquid crystal module.
A kind of LCD TV provided by the utility model and leakproof lamp thereof and the white liquid crystal module of pressure, owing to having adopted foam bar, replace the technological means that silica gel strip compresses light guide plate, the larger ratio of compression that utilizes foam bar to have on thickness with respect to silica gel strip, foam bar under condition of equivalent thickness is larger than the decrement of silica gel strip, and then not only can overcome lamp bar, iron backboard with and upper heat radiator moulding and/or assembling have certain deviation, avoided the leakage lamp phenomenon occurring in light inlet side, nor easily at the edge of light guide plate, apply excessive pressure, also the whiting light leakage phenomenon with regard to having avoided the part of light guide plate to occur because producing certain distortion.
