Problems solved by technology

[0003] At present, the capacitive touch screen with OGS (integrated touch) structure on the market, the circuit bridge is set on the FPC (flexible circuit board or soft board), but this circuit bridge method has great disadvantages: 1. The circuit bridge is on the FPC First, the FPC must have a large design space, which greatly restricts the structure of the terminal machine; second, the production requirements for the FPC are high, which restricts the production efficiency of the FPC; third, the pins that lead to the binding of the FPC and the touch screen Too much will greatly affect the binding process and production efficiency of the touch screen, and also increase the defect rate of the product

Abstract

The invention discloses an OGS capacitive touch screen. The OGS capacitive touch screen comprises an OGS panel, the OGS panel comprises a glass base layer and an ITO film arranged on the glass base layer, the ITO film comprises a window area and a panel area, the window area is located in the middle of the panel area, and the ITO film is provided with an ITO circuit layer. By the adoption of the OGS capacitive touch screen, the binding process of the touch screen can be simplified, the FPC space is saved, the design space of a whole machine is expanded, and production efficiency and yield are improved.

Description

technical field [0001] The invention relates to an OGS capacitive touch screen, in particular to an OGS capacitive touch screen widely used in electronic products such as mobile phones, GPS, and tablet computers. Background technique [0002] The capacitive touch screen is to paste a layer of transparent special metal conductive substance on the glass surface. When a finger touches the metal layer, the capacitance of the contact will change, causing the frequency of the oscillator connected to it to change. By measuring the frequency change, the touch position can be determined to obtain information. [0003] At present, the capacitive touch screen with OGS (integrated touch) structure on the market, the circuit bridge is set on the FPC (flexible circuit board or soft board), but this circuit bridge method has great disadvantages: 1. The circuit bridge is on the FPC First, the FPC must have a large design space, which greatly restricts the structure of the terminal machine;...
