Description
Technical field
The utility model relates to a kind of liquid crystal indicator that prevents the panel light leak.
Background technology
Conventional liquid crystal mainly comprises liquid crystal panel and module backlight, and make liquid crystal panel and module backlight combine by chase engaging, but this chase snap-in structure makes the frame that the liquid crystal panel marginal existence is certain, influence visible angle and the overall appearance of liquid crystal panel, especially under the situation of multi-display splicing, the frame of liquid crystal panel more influences spliced display effect.In order to overcome above-mentioned shortcoming, in the wide-angle liquid crystal display of New Times, all adopt narrow frame, wide angle of visibility and the design of integral type Bright View, allow more attractive in appearance, the fashion of display.The wide-angle liquid crystal display of this New Times has omitted traditional chase snap-in structure, changes liquid crystal panel glass into and directly fits fixing with module backlight by viscose.
But the fixing mode of this direct applying makes LCD that light leakage phenomena generally be arranged, namely under dark picture, there is regional area bright partially, influence display quality, reason is: the fixed form of liquid crystal panel glass and module backlight is the rigid fixing of single type glue frame, module backlight under external force or self slight distortion can drive liquid crystal panel glass and is out of shape together, thereby produce light leak; Simultaneously, if there is slight external force to act directly on the liquid-crystalline glasses face, deform because no buffer structure directly causes liquid crystal panel, also be easy to generate light leak.Therefore, be necessary to improve the fixed form of liquid crystal panel glass and module backlight, prevent the generation of light leak.
The utility model content
The utility model makes improvements at the problem that above-mentioned prior art exists, and namely the technical problems to be solved in the utility model provides a kind of liquid crystal indicator that prevents the panel light leak.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of liquid crystal indicator that prevents the panel light leak, comprise liquid crystal panel, module backlight and the preceding chase that liquid crystal panel and module backlight is clamped in the inside, be provided with the gluing frame between described liquid crystal panel and the module backlight, described module backlight comprises low glue frame, optical diaphragm group and backboard, and described gluing frame is connected with the low glue frame clearance fit.
Preferably, the sidewall of described gluing frame offers draw-in groove, and the sidewall of described low glue frame is provided with the grab with the draw-in groove clearance fit.
Preferably, leave the gap between the top of the top of described gluing frame and low glue frame.
Preferably, the top of described gluing frame offers spacing hole, and the top of described low glue frame is provided with the spacing fin that matches with spacing hole.
Preferably, stacked together by several concaveconvex structures between the top of the top of described gluing frame and low glue frame.
Compared with prior art, the utlity model has following beneficial effect: this liquid crystal indicator that prevents the panel light leak has reached soft fixing effect by two-piece type glue frame immobile liquid crystal panel and module backlight, and can reach effectively fixing simultaneously, can solve the light leakage phenomena under the dark picture effectively, promote the whole display quality of LCD and LCD TV, bring higher-quality visual enjoyment to the user.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Among the figure: the 1-liquid crystal panel, 2-module backlight, the 21-low glue frame, the 22-backboard, the 23-brightening piece, the 24-diffusion sheet, the 25-light guide plate, the 26-reflector plate, 27-reflects edge strip, chase before the 3-, 4-gluing frame, 5-draw-in groove, 6-grab, 7-concaveconvex structure, 8-pad.
Embodiment
As shown in Figure 1, a kind of liquid crystal indicator that prevents the panel light leak, comprise liquid crystal panel 1, module backlight 2 and the preceding chase 3 that liquid crystal panel 1 and module backlight 2 is clamped in the inside, be provided with gluing frame 4 between described liquid crystal panel 1 and the module backlight 2, described module backlight 2 comprises low glue frame 21, optical diaphragm group and backboard 22, and described gluing frame 4 is connected with low glue frame 21 clearance fit.
In the present embodiment, the sidewall of described gluing frame 4 offers draw-in groove 5, the sidewall of described low glue frame 21 is provided with the grab 6 with draw-in groove 5 clearance fit, the clearance fit here specifically is the clearance fit between the bottom surface of the bottom surface of grab 6 and draw-in groove 5, and described grab 6 has limited getting loose of gluing frame 4 and low glue frame 21 vertical directions.Gap between the bottom surface of the bottom surface of described grab 6 and draw-in groove 5 is 0.5mm, gap width in actual applications should be adjusted to suitable point or scope according to different display size sizes, this gap has compensated the distortion of module 2 backlight, makes liquid crystal panel 1 keep the nature formation state.
