Hereinafter reference will be made to the drawings is more fully described the utility model.In various figures, identical element is using similar Reference numeral represent.For the sake of clarity, the various pieces in attached drawing are not necessarily to scale.Furthermore, it is possible to it is not shown Certain well known parts.
Many specific details of the utility model, such as the structure of device, material, size, place is described hereinafter Science and engineering skill and technology, to be more clearly understood that the utility model.But just as the skilled person will understand, The utility model can not be realized according to these specific details.
In the following, the utility model is described in detail with reference to attached drawing.
Fig. 2 a show the sectional schematic diagram of adhesive tape in the utility model;Fig. 2 b show that the vertical view of adhesive tape in the utility model is shown It is intended to;Fig. 3 shows the structure diagram of liquid crystal display device non-light source side in the utility model;As shown in Fig. 2 a to Fig. 3, this reality It is compounded to form with the adhesive tape 100 in novel by the first composite bed 110 and the second composite bed 120.The adhesive tape 100 includes being one Whole first part 101, second part 102 and Part III 103.First part 101 is five-layer structure, including heap successively Folded the second base material 121, the second glue-line 122, the first base material 111, the first glue-line 112 and the first release paper 113;Second part 102 be six layer structure, including stack gradually the second base material 121, the second glue-line 122, the second release paper 123, the first base material 111st, the first glue-line 112 and the first release paper 113;Part III 103 is four-layer structure, including the second base material stacked gradually 121st, the second glue-line 122, the second release paper 123 and the first release paper 113.Wherein, the second base material 121, the second glue-line 122 The second composite bed 120 is formed, the first base material 111, the first glue-line 112 form the first composite bed 110.
Second release paper 123 is connected with release paper and tears hand 124, and the second composite bed 120 is detached from convenient for the second release paper 123. And second the area of composite bed 120 be greater than or equal to the area of the second release paper 123, the area of the second release paper 123 is more than etc. In the area of the first composite bed 110, the area of the first release paper 113 is more than the area of the second composite bed 120.First part 101 The design of five-layer structure causes 120 close adhesion of the first composite bed 110 and the second composite bed;In the second glue in second part 102 Second release paper 123 is set between layer 122 and the first base material 111 so that the first composite bed 110 and the second composite bed 120 are each other Independent action is in certain parts of liquid crystal display device 10;Second is substantially contained only in the four-layer structure of Part III 103 120 and first release paper 113 of composite bed and the second release paper 123.And the length of 100 second part 102 of adhesive tape is more than liquid The profile height of LCD panel, the length of Part III 103 are more than the profile height of liquid crystal display device dorsulum.
First composite bed 110 and the second composite bed 120 are flexibly bonded or separated by adhesive tape 100, and bonding design is promoted The bonding force of first composite bed 110 and the second composite bed 120 herein, separate design so that the first composite bed 110 and second is multiple It is very flexible in practical applications to close layer 120.It should be noted that the first base material 111 that adhesive tape 100 includes in the utility model with And second the material of base material 121 can unanimously can also be different, material therefor all have good insulating properties, light-proofness and Profile pattern etc..
Liquid crystal display device 10 includes display panel 11 and backlight module.Backlight module includes backboard 16, in backboard 16 The reflector plate 15 that is sequentially arranged above, light guide plate 14, optical diaphragm group 13 and under 16 side of backboard and display panel 11 The glue frame 17 of side forms gap 18 between glue frame 17 and reflector plate 15, light guide plate 14 and optical diaphragm group 13.Reflector plate 15, Light guide plate 14, optical diaphragm group 13 and display panel 11 are all placed in the receiving space surrounded by backboard 16.In optical diaphragm 13 top of group is equipped with display panel 11, and display panel 11 is unobstructed close to the side of backboard 16 and the formation of backboard 16 gap.
First glue-line 112 of 100 first part 101 of adhesive tape is attached at the portion of upper surface of display panel 11 and with being attached at The upper polaroid of 11 upper surface of display panel maintains an equal level, and the first composite bed 110 of 100 second part 102 of adhesive tape is with display panel 11 Side and the portion lower surface of display panel 11, the length of second part 102 are attached at close to the contraposition extension of the side of backboard More than the profile height of display panel 11 so that the first composite bed 110 has with the down polaroid for being attached at 11 lower section of display panel It is overlapping, and then good shaded effect is played to the edge of display panel 11.100 second part 102 of adhesive tape and Part III 103 the second composite bed 120, which is continuously attached at the edge upper surface of display panel 11 and thus extends, is attached at backboard 16 Side and portion lower surface, the length of Part III 103 are more than the profile height of backboard 16, and the second composite bed 120 is used for will Display panel 11 is fixed in backlight module, plays the role of fixed display panel 11 and shading.
The part that first composite bed 110 and the second composite bed 120 overlap causes adhesive type cohesive force measuring to greatly promote, both solved by Be attached at that the composite bed of 11 upper surface of display panel easily tilts caused by adhesive tape area of attachment is small caused by narrow frame asks The problem of inscribing, and then effectively preventing 11 edge light leakage of display panel, and the first composite bed 110 is caused to be attached at display panel 11 Area increase, the problem of on the one hand effectively preventing 11 light leakage of display panel, on the other hand also avoid display panel 11 with The problem of 16 short circuit of backboard, while overlapping part has restrained the movement of the first composite bed 110.
