Problems solved by technology

In this way, the adhesion between the auxiliary silver wire and the auxiliary conduction section of the main silver wire is low. When the product is used in the terminal, due to the external force on the silver wire, the silver wire is easy to delaminate with the glass substrate, resulting in air leakage; Ring, poor product appearance and poor linear drift caused by Newton ring
The silver wire is easy to be layered with the glass substrate, and it will also cause the silver wire to be partially broken, resulting in failure of the touch function of the product

Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0009] Such as figure 1 As shown, a resistive touch screen of the present invention includes a glass substrate 1, a silver wire 2 and a film 3, and the silver wire 2 includes a main silver wire and an auxiliary silver wire, between the glass substrate 1 and the main silver wire and the auxiliary silver wire Both are provided with an ITO layer 4 .

[0010] The above-mentioned ITO layer 4 is an indium tin oxide layer plated on a soda-lime-based or silicon-boron-based glass substrate by magnetron sputtering.

[0011] The present invention and the existing comparative product were steamed for 4 hours, the silver wire of the present invention adhered intact, while the silver wire of the comparative product fell off, and the silver wire of the present invention remained intact after steaming for 12 hours.

[0012] Finally, it should be no...

Abstract

The invention discloses a resistive touch screen, which comprises a glass substrate, a silver wire and a film, wherein the silver wire comprises a main silver wire and an auxiliary silver wire; and an indium tin oxide (ITO) layer is arranged among the glass substrate, the main silver wire and the auxiliary silver wire. The adhesion force between the auxiliary silver wire and the auxiliary conduction section of the main silver wire is effectively increased, when the product is used at the terminal, the silver wire is difficult to be layered with the glass substrate under the action of external force, and gas leakage is hardly caused; bad appearance of a Newton's ring and bad linear drift brought by the Newton's ring are hardly caused; and meanwhile, the phenomenon that the touch function of the product is ineffective due to local breakage of the silver wire is hardly caused, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to a resistive touch screen. Background technique [0002] Currently, as an input device, a touch screen is widely used in various display devices, such as mobile phones. There are many types of resistive touch screens for mobile phones, such as: G+G (indicating that the touch screen is made of glass to glass), F+G (indicating that the touch screen is made of film and glass), etc.; For resistive touch screens, there is an ITO layer only where the main silver line is connected to the ITO, and the auxiliary silver line and the main silver line are not. In this way, the adhesion between the auxiliary silver wire and the auxiliary conduction section of the main silver wire is low. When the product is used in the terminal, due to the external force on the silver wire, the silver wire is easy to delaminate with the glass substrate, resulting in air leakage; Ring, poor product appearance and poor linear drift caused by Newton rings.
