Embodiment
Fig. 2 is the synoptic diagram of the double sticky tape of one embodiment of the invention.Please refer to Fig. 2, double sticky tape 240 comprises flexible shading body 242, first adhesion layer 244 and second adhesion layer 246.Flexible shading body 242 has each other relative first surface 242a and second surface 242b.The color of the flexible shading body 242 of present embodiment for example is black or other color that can be in the light fully.
The first surface 242a that first adhesion layer 244 is disposed at flexible shading body 242 goes up and has the respect to one another the 3rd surperficial 244a and the 4th a surperficial 244b.The 3rd surperficial 244a is attached to the first surface 242a of flexible shading body 242, and the stickiness of the 3rd surperficial 244a is greater than the stickiness of the 4th surperficial 244b.In the present embodiment, the stickiness of the 3rd surperficial 244a is the twice to three times of the stickiness of the 4th surperficial 244b.
The second surface 242b that second adhesion layer 246 is disposed at flexible shading body 242 goes up and has the respect to one another the 5th surperficial 246a and the 6th a surperficial 246b.The 5th surperficial 246a is attached to the second surface 242b of flexible shading body 242, and the stickiness of the 5th surperficial 246a is greater than the stickiness of the 6th surperficial 246b.In the present embodiment, the stickiness of the 5th surperficial 246a is the twice to three times of the stickiness of the 6th surperficial 246b.In addition, second adhesion layer 246 of present embodiment also has first and sticks together the 246c of portion and second and stick together the 246d of portion, and first stick together the 246c of portion and second and stick together the 246d of portion separation I, but the present invention is not as limit.
Fig. 3 is a kind of schematic top plan view with liquid crystal display device module of double sticky tape of present embodiment.Fig. 4 is the diagrammatic cross-section of the liquid crystal display device module of Fig. 3 along line A-A.Below be applied to liquid crystal display device module 200 for double sticky tape 240 situation explain.In this mandatory declaration is that the double sticky tape 240 among Fig. 4 is to indicate to clearly illustrate with oblique line.Please refer to Fig. 3 and Fig. 4, liquid crystal display device module 200 comprises housing 210, backlight module 220, display panels 230 and many double sticky tapes 240 (Fig. 3 schematically illustrates two).Housing 210 comprises base 212 and the framework 214 that is disposed at base 212.Backlight module 220 be disposed at base 212 and by 214 of frameworks around.
One end of each double sticky tape 240 sticks in the base 212 of housing 210, make that the part of each double sticky tape 240 is exposed to outside.Between the framework 214 and display panels 230 of each double sticky tape 240 bending extend past housings 210, make the other end of each double sticky tape 240 extend between display panels 230 and the backlight module 220 and the edge 234a of the non-display surface 234 of contiguous display panels 230.
In detail, the 4th surperficial 244b of first adhesion layer 244 of each double sticky tape 240 is attached to the edge 234a of the non-display surface 234 of display panels 230.In the present embodiment, first adhesion layer 244 is only between display panels 230 and backlight module 220.Because being end points from flexible shading body 242, first adhesion layer 244 do not begin configuration; So double sticky tape 240 is exposed to and outer that part ofly only has the single face stickiness, that is the being exposed to outer first surface 242a that first adhesion layer 244 can not be disposed at double sticky tape 240 goes up and makes that being exposed to outer first surface 242a does not have a stickiness.The 6th surperficial 246b of second adhesion layer 246 of each double sticky tape 240 is attached to base 212, framework 214 and backlight module 220.In the present embodiment, first of second adhesion layer 246 sticks together the outside, bottom surface 212a that the 246c of portion is attached to base 2 12, and second the sticking together the 246d of portion and be attached to framework 214 and backlight module 220 at least of second adhesion layer 246.
When liquid crystal display device module 200 runnings, the flexible shading body 242 of these double sticky tapes 240 avoids the edge of the display surface 232 of display panels 230 to produce light leakage phenomena.When liquid crystal display device module 200 assemblings were accomplished, first adhesion layer 244 and second adhesion layer 246 of these double sticky tapes 240 were fixed the relevant position of above-mentioned these members of liquid crystal display device module 200.Through from the above, the double sticky tape 240 of the liquid crystal display device module 200 of present embodiment has shading and fixing function.Therefore, compare with known technology, the assembling mode of the liquid crystal display device module 200 of present embodiment is comparatively simple and easy, built-up time is short and assembly cost is lower.
When liquid crystal display device module 200 need be disassembled; The end that each double sticky tape 240 sticks in the base 212 of housing 210 originally at first breaks away from base 212; Then each double sticky tape 240 is outwards stretched, make display panels 230 break away from framework 214 and backlight module 220.Because the stickiness of the 3rd surperficial 244a of double sticky tape 240 is greater than the stickiness of the 4th surperficial 244b; And the stickiness of the 5th surperficial 246a is greater than the stickiness (visible Fig. 2) of the 6th surperficial 246b; So after liquid crystal display device module 200 was disassembled, double sticky tape 240 was difficult for residual emplastic on backlight module 220, display panels 230 and housing 210.Therefore, liquid crystal display device module 200 quick releases of present embodiment and then re-assembly.
In sum, the double sticky tape of embodiments of the invention and liquid crystal display device module have following one of them or other advantage at least:
One, because double sticky tape has shading and fixing function, so compare with known technology, the assembling mode of the liquid crystal display device module of embodiments of the invention is comparatively simple and easy, built-up time is short and assembly cost is lower.
Two, since the stickiness of each adhesion layer inside surface of double sticky tape greater than the stickiness of its outside surface, so use the liquid crystal display device module quick release of double sticky tape and then re-assembly.
Though the present invention with embodiment openly as above; But it is not that any those skilled in the art is not breaking away from the spirit and scope of the present invention in order to qualification the present invention; When can doing a little change and modification, so protection scope of the present invention is as the criterion when looking the accompanying Claim book person of defining.
