Abstract

The invention is applicable to the field of display screens and provides a touch screen and a manufacturing method thereof. The touch screen comprises cover plate glass and a thin film transistor (TFT) display. An induction electrode of the touch screen is manufactured on the cover plate glass. A driving electrode of the touch screen is manufactured on the surface of color glass of the TFT display. One side of the cover glass with the induction electrode is bonded with one side of the TFT display with the driving electrode through optical glue. Two structures of OGS and ON-CELL are combined, the induction electrode and the driving electrode of a touch sensor are manufactured on the touch screen cover plate glass and the TFT display color glass respectively, and slimness of touch products and optimization of the touch performance are achieved.

Description

technical field [0001] The field of the display screen of the present invention particularly relates to a touch screen and a manufacturing method thereof. Background technique [0002] In the traditional touch screen structure, the touch screen is formed by pasting two pieces of glass or one piece of glass and one piece of film, that is, the sensor glass is bonded with another piece of cover glass or film to form a touch screen, and then the touch screen is attached to the LCD panel. The touch screen in this type of display screen is made of two pieces of glass or glass and film, so the overall light transmittance is relatively low, and it is relatively thick and heavy. [0003] With the rapid development of touch screen products, thinning has become an inevitable trend. Various touch screen manufacturers have launched different product structures to meet the market demand for thinning, including OGS and ON-Cell technology. Such as figure 1 As shown, the ON-Cell structure ...
