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

Abstract

The invention discloses an indium tin oxide (ITO) through hole integrated capacitive touch screen and a production method thereof. The ITO through hole integrated capacitive touch screen comprises a transparent glass substrate, and a black resin layer, an ITO electrode, a first insulating layer, an ITO through hole electrode, a metal electrode and a second insulating layer which are sequentially stacked on the transparent glass substrate. The ITO electrode comprises an ITO electrode 1 and an ITO electrode 2 and has a regular pattern structure, wherein the ITO electrode 1 and the ITO electrode2 are arranged on the same layer, are independent to each other, are insulated with each other and are designed perpendicularly. The transparent substrate comprises a window area and a non-window area. The black resin layer is distributed in the non-window area of the display screen. The line of the metal electrode is only wired in the area of the black resin layer. By reasonably designing the stacking structure and the ITO conduction method of the capacitive touch screen and by adopting an ITO through hole method to conduct ITO signal electrodes up and down, the light transmittance, the working stability and the touch sensitivity of the capacitive touch screen are effectively improved.

Description

technical field [0001] The invention relates to the technical field of capacitive touch screens, in particular to an integrated 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 recogniz...
