Touch screen

The utility model relates to the technical field of backlight modules, in particular to a touch screen. The touch screen comprises a glass substrate, a PET film layer adheres to the upper surface of the glass substrate through a first optical adhesive layer, and the first optical adhesive layer and the PET film layer are completely overlapped and extend towards the outer side of the glass substrate to exceed the surface of the glass substrate to form an extension part; and protective glue is filled between the lower surface of the extension part and the glass substrate. According to the touch screen, the design of completely covering the tempered film and using the protective glue for edge sealing is adopted, so that a display screen is more attractive, and dirt cannot be hidden at the same time. 本申请涉及背光模组技术领域，具体涉及一种触摸屏。所述触摸屏包括：玻璃基板，所述玻璃基板的上表面通过第一光学胶层粘贴有PET膜层，所述第一光学胶层和所述PET膜层完全叠合并向所述玻璃基板的外侧延伸至超出所述玻璃基板的表面构成延伸部，所述延伸部的下表面与所述玻璃基板之间填充有保护胶。本申请的触摸屏，通过采用使用完全覆盖钢化膜和使用保护胶封边的设计，使显示屏更加美观的同时，不会藏污垢。
