Abstract

The invention provides a touch panel assembly structure. Based on the existing assembly structure, a long-strip film and a cushioning material layer are added, and the touch panel can be easily separated from a display panel when being disassembled by using the low viscosity of an adhesive tape. The shortcoming that the touch panel cannot be easily separated from the display panel due to the viscosity of a double-sided adhesive tape in the prior disassembly process, the panel has no residual adhesive left after being disassembled, and the touch panel can avoid from being damaged during the disassembly process, so that the touch panel can be repeatedly assembled.

Description

technical field

[0001] The present invention relates to a touch panel, in particular to a touch panel assembly structure. Background technique

[0002] The touch display is to fix a touch panel on the display panel, and the commonly used fixing methods include pressing sheets and adhesives. The method of pressing and fixing the touch panel on the display panel with a pressing sheet is likely to cause deformation of the touch panel, and dust is easy to enter between the display panel and the touch panel, and it is also prone to displacement during transportation. In addition, when the size of the panel changes , it is more necessary to modify the mold, its adaptability is poor and the cost is higher than that of viscose fixing method.

[0003] see figure 1 and figure 2 , the existing adhesive fixing method utilizes a buffer material (poron) 10 with a layer of double-sided adhesive tape 12, 12' on both sides, and sticks one side to the touch panel 16 and the other side to ...

Embodiment Construction

[0037] Please refer to image 3 , which is a touch panel assembly structure according to the first embodiment of the present invention, and is used to fix a touch panel 20 on a display panel 22 of a display. The touch panel assembly structure includes a strip film 24, a first buffer material layer 28 and a second cushioning material layer 32 .

[0038] The strip film 24 is arranged between the touch panel 20 and the display panel 22. The touch panel can be a sonic touch panel, a resistive touch panel or a capacitive touch panel. The material of the strip film 24 can be Mylar or PET polyester film, the tensile strength of polyester film can reach 180 million Pa (Mpa), the elongation at break is 120%, and the thermal shrinkage rate is only 1.2%. And the length of the strip film 24 needs to be such that it can protrude 15-20 mm outside the touch panel 20 , and the protruding part can be attached to the display panel 22 downward at ordinary times. In this embodiment, a strip fil...
