Abstract
The utility model discloses a liquid crystal display television and a lateral light leakage prevention liquid crystal display module of the liquid crystal display television. The liquid crystal display module comprises a liquid crystal display panel, a front iron frame, a middle frame support and an iron back plate, the middle frame support and the iron back plate are arranged on the inner side of the front iron frame in a sleeved mode, the edge of the liquid crystal display panel is clamped between the front frame edge of the front iron frame and the inner frame of the middle frame support, wherein after assembling, at the buckling position of a clamping hook of the middle frame support and a clamping buckle of the iron back plate, the end face of the middle frame support is arranged on the outer wall side of the iron back plate, and the end face of the iron back plate is arranged on the inner wall side of the middle frame support. Due to the fact that the method that the end faces exceed the contact position is adopted at the buckling position of the middle frame support and the iron back plate, light is prevented from being leaked through the overlapped side wall of the end portion of the middle frame support and/or the iron back plate, the situation that light emitted by the inner portion of the liquid crystal display module is leaked out of an opening groove in the side face of the front iron frame when the liquid crystal display module works is avoided, and therefore pasted black PET adhesive tape is eliminated. Production cost is lowered, and meanwhile production efficiency is improved.
Description
Technical field
The utility model relates to LCD TV and liquid crystal module field thereof, in particular a kind ofly prevents that the assembly structure of light leakage phenomena from appearring in liquid crystal module side.
Background technology
As shown in Figure 1, Fig. 1 is the partial sectional view that liquid crystal module of the prior art is positioned at its frame place, LCD TV of the prior art, the assembly structure of its liquid crystal module is generally by liquid crystal panel (being OPEN_CELL) 110, front chase 120, the main parts size such as middle frame support 130 and iron backboard 140 are assembled, described middle frame support 130 and described iron backboard 140 are all sleeved on the inner side of described front chase 110, the end that described middle frame support 130 contacts with described iron backboard 140 can partly overlap or be all overlapping, the edge of described liquid crystal panel 110 is clipped between the front edge 121 of described front chase 120 and the interior edge 131 of described middle frame support 130.
Along with the frivolous narrow development trend of current LCD TV, the border width of liquid crystal module also requires more and more narrow, for this reason, shown in Fig. 2, Fig. 2 is the partial side view that liquid crystal module of the prior art is positioned at its frame fastening place, on the sidewall of described front chase 120, offer an open slot 122, for holding on described middle frame support 130 sidewalls the grab 144 that is fastened on this buckle 133 on the buckle 133 that protrudes laterally and described iron backboard 140.
In order to pursue the super narrow frame effect of LCD TV, toward contact meeting, by black, make the color of middle frame support 230 (moulding) into white, yet, as long as in described middle frame support 130 and iron backboard 140 arbitrary or two slightly distortion or the sizes of working it out have a deviation, or both assemble not in place, at the large oval place shown in Fig. 2, be the fastening place of buckle 133 with the grab 144 of described iron backboard 140 of described middle frame support 130, all can when LCD TV is being held, occur comparatively significantly side leakage optical phenomenon.
Again in conjunction with shown in Fig. 3, Fig. 3 is the partial perspective view that liquid crystal module of the prior art iron backboard used is positioned at grab place, grab 144 on traditional iron backboard 140 is mostly the mode moulding that adopts blanking punching press, at described grab 144, for catching on the end of described middle frame support 130 buckles 133, have an oblong slots 144a who stays after blanking, and the light spilling from the ellipse shown in Fig. 1 spills through this oblong slots 144a place just.
The large oval place shown in Fig. 2 namely, ellipse place shown in Fig. 1 in fact, in addition, the little oval place of shown in Fig. 2 two, in the scope of the open slot 122 of described front chase 120,, also can there is a small amount of side leakage optical phenomenon because of foozle and/or rigging error in the end contact place of described middle frame support 130 and iron backboard 140.
The method of traditional solution liquid crystal module side leakage light normally, the PET adhesive tape of pasting black on the lateral surface at described middle frame support 130 and iron backboard 140 end contact places prevents the phenomenon of side leakage light, but so but increased the production cost of adhesive tape, also the installation time that has extended liquid crystal module, has reduced production efficiency simultaneously.
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 liquid crystal module of anti-side leakage light, can also can prevent that the phenomenon of side leakage light from appearring in the buckle place of middle frame support without black PET adhesive tape.
Meanwhile, the utility model also provides a kind of LCD TV, can low cost prevent side leakage optical phenomenon.
The technical solution of the utility model is as follows: a kind of liquid crystal module of anti-side leakage light, comprise liquid crystal panel, 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 clipped between the front edge of described front chase and the interior edge of described middle frame support, wherein: after assembling at the fastening place of the grab of described middle frame support and the buckle of described iron backboard, the end face of described middle frame support is positioned at the outer wall side of described iron backboard, the end face of described iron backboard is positioned at the inwall side of described middle frame support.
The liquid crystal module of described anti-side leakage light, wherein: at the grab place of described iron backboard, the part, end of described iron backboard is extended with one section of rib.
The liquid crystal module of described anti-side leakage light, wherein: at the buckle place of described middle frame support, the part, end of described middle frame support is extended with one section of shelves muscle.
The liquid crystal module of described anti-side leakage light, wherein: the grab of described iron backboard passes through without the moulding of blanking impact style.
A LCD TV, comprises liquid crystal module, wherein: described liquid crystal module is set to the liquid crystal module of the anti-side leakage light described in above-mentioned middle any one.
The liquid crystal module of a kind of LCD TV provided by the utility model and anti-side leakage light thereof, because having adopted end face, the fastening place at middle frame support and iron backboard surpasses the way of contact position, utilize the overlapping sidewall of middle frame support and/or iron backboard end sections to stop light to spill, avoided the liquid crystal module light that send its inside when work to spill at the open slot place of chase side in the past, saved thus stickup black PET adhesive tape, reduce production cost, also improved production efficiency simultaneously.
