Background technique

Touch electronic products are the development trend of light weight, miniaturization and humanization of modern 3C electronic products, which makes various electronic products change from traditional keyboard, mouse or remote control input control to direct touch on the screen Operation, in addition to being simpler and more convenient to use, also makes electronic products have the advantages of being thin and light and easy to carry.

Touch electronic products combine a touch module with a display, for example, a touch panel (TouchPanel) is combined with an LCD, so that users can directly perform touch operations on the graphic interface displayed on the display. At present, the technology used to combine the touch module with the display is to use liquid adhesive to coat the surrounding edges of the touch module and the display surface and cure the adhesion, or to use double-sided tape to stick the surrounding edges of the touch module and the display surface The edges are joined by assembly. However, when it is necessary to disassemble and separate the touch module and the display due to defects or maintenance during the production process of the touch-sensitive electronic product, the method of using liquid adhesive or double-sided tape is not easy to disassemble due to its strong viscosity. Improper force may damage the touch module and display, and it is easy to leave cured adhesive or part of the double-sided tape body on the surface, which is difficult to remove, and it is generally easy to scratch and damage the surface of the touch module and display by scraping with tools. Therefore, the current liquid adhesives and double-sided tapes make it difficult and labor-intensive to reassemble and disassemble the touch-sensitive electronic products.
