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 a novel ITO (indium tin oxide) through hole integrated capacitive touch screen and a production method thereof. The ITO through hole integrated capacitive touch screen comprises a transparent glass substrate or resin substrate, and further comprises a silicon dioxide layer, a niobium pentoxide layer, a black resin layer, ITO electrodes, a first insulating layer, an ITO through hole electrode, a metal electrode and a second insulating layer, which are sequentially stacked onto the transparent glass substrate. The silicon dioxide layer fully covers the glass substrate, and the niobium pentoxide layer fully covers the silicon dioxide layer. The ITO electrodes include an ITO electrode 1 and an ITO electrode 2 which have regular pattern structures. By means of reasonable design of the stack structure of the capacitive touch screen and the ITO communication way, the ITO signal electrodes are vertically communicated through ITO through holes, transmissivity of the capacitive touch screen is effectively improved, visibility of ITO patterns is reduced, and reliability of the touch screen is further 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...
