Abstract

The invention discloses a touch screen, which comprises a circuit layer and a lead wire led out from the circuit layer. The touch screen is characterized by also comprising an upper line ITO film attached to the upper surface of the circuit layer, a mirror face attached to the upper surface of the upper line ITO film through a non-carrier optical adhesive tape, a lower line ITO film attached to the lower surface of the circuit layer, and a support plate attached to the lower surface of the lower line ITO film through the non-carrier optical adhesive tape. The invention also discloses a corresponding touch screen manufacturing method. The touch screen is thin and has extrusion resistance and high lead wire bending degree.

Description

technical field [0001] The invention relates to touch screen technology, in particular to a touch screen and a manufacturing method thereof. Background technique [0002] The touch screen is an input device that can complete corresponding operations by touching the viewed interface. It allows easy and visual operation of the system. The button can be omitted separately, so that the scope of use becomes wider and wider. And now the mainstream is using a touch screen that combines glass and film. Due to the thickness of the glass used in the traditional touch screen, it will inevitably crack and shatter the screen when it is dropped or squeezed; due to the limited bending degree of the glass, it has a certain impact on the location and environment of use. stricter requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a touch screen, which is thin, extrusion-resistant, and has a high bending degree of le...
