A kind of ito through hole capacitive touch screen and its manufacturing method

Abstract

The invention discloses an indium tin oxide (ITO) through hole capacitance touch screen and a method for manufacturing the same. The ITO through hole capacitance touch screen comprises a decorative glass substrate, a capacitance functional substrate, an ITO electrode, a first insulating layer, an ITO through hole electrode, a metal electrode and a second insulating layer, wherein the capacitance functional substrate is overlapped on the decorative glass substrate by an optical adhesive layer; the ITO electrode, the first insulating layer, the ITO through hole electrode, the metal electrode and the second insulating layer are sequentially overlapped on the capacitance functional substrate; the ITO electrode comprises a capacitance screen driver (an ITO electrode 1) and an induction electrode (an ITO electrode 2), which are in a regular graphic structure; and the ITO electrode 1 and the ITO electrode 2 are on the same layer, independent of each other, insulated from each other, and vertically designed. By reasonably designing an overlapping structure of the capacitance touch screen and an ITO conduction mode, and by conducting ITO signal electrodes from up to down in an ITO through hole mode, the light transmission rate, operating stability and touch sensitivity of the capacitance touch screen are effectively improved.

Description

technical field [0001] The invention relates to the technical field of capacitive touch screens, in particular to a capacitive touch screen designed through ITO through holes and a manufacturing method thereof. Background technique [0002] With the development of electronic technology, the keyboards or mice of mobile phones, digital cameras, handheld game consoles, car DVDs, MP3s, instruments, etc. are gradually replaced by touch screens. Touch screen products were not very popular a few years ago, but as people have more and more contacts with touch screen products, they have been recognized by more people in the past two years, and the development speed has gradually accelerated. The rapid growth of touch screen has not only aroused more fierce competition in the industry, but also indirectly promoted the development of technology. Its multi-touch operation method has raised the influence of touch screen products to a new level, and has gradually been recognized by people...

AI Technical Summary

Problems solved by technology

[0008] However, the capacitive touch screen using the traditional design scheme will have the defects of low light transmittance and poor working stability. The light transmittance of the capacitive touch screen with the traditional design scheme is difficult to break through 80%, and when the overall force is bent and deformed, it is easy Separation occurs at the interface, resulting in electrode disconnection, touch failure, and damage to the touch-sensing components
