Problems solved by technology

As mentioned above, the ITO material itself is not resistant to high temperature, acid and alkali. If the cover glass is physically toughened, it needs to be carried out at a high temperature of about 450 ° C ~ 600 ° C (close to the softening temperature of glass). ITO material At such a high temperature, the surface resistance will increase sharply, and the conductivity will drop sharply.
However, if the cover glass is chemically tempered, it is necessary to immerse the ITO conductive substrate in a high-temperature molten salt for alkali ion exchange, which is also in a high-temperature environment, which is not conducive to the conductive stability of the ITO material.

Abstract

The invention relates to a touch screen technology, in particular to a production method of a double-screen integrated touch screen with FTO (fluorine-doped tin oxide) conductive glass. The double-screen integrated touch screen comprises a glass substrate, wherein an FTO conductive film is deposited on the glass substrate to form an FTO conductive glass substrate; the FTO conductive glass substrate is patterned, cut and toughened; conductive regions are electrically connected; ink is printed on the edge of the touch screen; and a conductor line is printed or pasted on the edge of the touch screen. According to the method, the FTO is adopted as a conductive material of a touch sensor; the touch sensor and a cover plate are integrated onto the glass substrate through toughening treatment; double-screen integration of the touch sensor and the glass cover plate is realized; the thickness and weight of the touch screen are reduced effectively; the production technology is simplified; the investment of production equipment is reduced, and the production cost is saved greatly.

Description

Technical field [0001] The invention relates to touch screen technology, in particular to a production method of FTO conductive glass used in a two-screen-in-one touch screen. Background technique [0002] As a new human-computer interaction device, touch screen is receiving more and more attention because of its simple and convenient input method. Its application fields are becoming more and more extensive, from game consoles to handheld computers, mobile phones, digital cameras, GPS (global satellite navigation system), POS (point of sale terminal), vehicle display screens, public information query systems and other electronic product fields. The market prospects are extremely broad. [0003] The current common capacitive touch template is mainly composed of the following parts: touch sensor (Sensor), cover (Cover lens) and touch chip (FPC IC), etc. Among them, the transparent conductive film coated on the touch sensor currently mainly uses Indium Tin Oxide (ITO) as its raw mat...
