Embodiment
For further setting forth the utility model for the technological means reaching predetermined utility model object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to embodiment of the present utility model, structure, feature and effect thereof, be described in detail as follows.
Fig. 2 is the structural representation of panel module in the utility model embodiment.As shown in Figure 2, panel module of the present utility model comprises display panel 21 and cover plate 22, one side surface of display panel 21 is pasted with polaroid 211, cover plate 22 is positioned at the side being pasted with polaroid 211 of display panel 21, and is pasted by optical cement 23 between cover plate 22 and upper polaroid 211.
Further, optical cement 23 comprises the first glue-line 231 and one-body molded between the second glue-line 232, first glue-line 231 and the second glue-line 232.In the present embodiment, optical cement 23 is a cuboid, is understandable that, the shape of optical cement 23 is not limited thereto, and shape can change with panel-shaped.The thickness of the first glue-line 231 is equal with the thickness of the second glue-line 232, and the area equation of the area of the first glue-line 231 and the second glue-line 232.It should be noted that, the thickness of the first glue-line 231 also can be different from the thickness of the second glue-line 232, the glue material of different-thickness can be selected to combine according to the optical requirement of product, operational characteristic.Further, first glue-line 231 is positioned at the side towards display panel 21 of optical cement 23, and the surperficial 231a of the first glue-line 231 and upper polaroid 211 are pasted, second glue-line 232 is positioned at the side towards cover plate 22 of optical cement 23, and the surperficial 232a of the second glue-line 232 and cover plate 22 are pasted, the viscosity on the surface of the first glue-line 231 is less than the viscosity on the surface of the second glue-line 232.
In the utility model, viscosity due to the surface of the first glue-line 231 is less than the viscosity on the surface of the second glue-line 232, and be formed in one between the first glue-line 231 and the second glue-line 232, make the bounding force between the first glue-line 231 and the second glue-line 232, and second bounding force between glue-line 232 and cover plate 22 be greater than bounding force between the first glue-line 231 and upper polaroid 211, so, when disassembling this panel module, the surperficial 231a of the first glue-line 231 is more easily separated with between upper polaroid 211, thus make optical cement 23 full wafer peel off removal with cover plate 22 from display panel 21, not residual (or only remaining on a small quantity) optical cement on upper polaroid 211, polaroid 211 in scratch when can prevent follow-up removing residual optical glue, and due to cover plate 22 be that intensity is large, scratch resistant tempered glass, cover plate 22 is not easily scratched during follow-up removal residual optical glue, be conducive to the heavy industry maintenance of panel module.
Connect above-mentioned, particularly, optical cement 23 can be acrylic glue.As shown in Figure 3, when making optical cement 23, in release liners 234, first first can apply ground floor optics acrylic glue (low-viscosity acrylic glue) to form the first glue-line 231, after ground floor optics acrylic glue primary solidification, second layer optics acrylic glue (the acrylic glue of high viscosity) is applied to form the second glue-line 232 at the upper surface of ground floor optics acrylic glue, finally, one deck release liners 233 is attached at the upper surface of the second glue-line 232.Before using, according to panel 21 and the size of cover plate 22, optical cement 23 can be cut into required size.Especially, in order to distinguishable first glue-line 231 and the second glue-line 232 in use, also can make marks to distinguish in the release liners of the first glue-line 231 or the second glue-line 232 respective side.When making optical cement 23, can according to the material characteristic of upper polaroid 211 with cover plate 22, adhesion strength during laminating between each element requires and after stripping, the residual quantity of optical cement requires to adjust the viscosity of the first glue-line 231 and the second glue-line 232, the high penetration characteristic of optical cement 23 should be retained, the heavy industry that can be beneficial to defective products again under the effective combination ensureing cover plate 22 and display panel 21 is disassembled (disassembling the surface that rear optical cement 23 remains in cover plate 22), the characteristic of optics acrylic glue and the preparation method of optical cement know for those skilled in the art, do not repeat them here.
The utility model also provides a kind of touch screen, and this touch screen comprises panel module as above.
To sum up, optical cement in panel module of the present utility model comprises integrated first glue-line and the second glue-line, one side surface of the first glue-line and the upper polaroid of display panel are fitted, one side surface of the second glue-line and cover plate are fitted, viscosity due to the first glue-line is less than the viscosity of the second glue-line, when disassembling this panel module, more easily be separated between the surface of the first glue-line of optical cement and the upper polaroid of display panel, optical cement on upper polaroid can be reduced remain, polaroid in scratch when preventing follow-up removing optical cement.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solutions of the utility model content, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
