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) gap-bridge integrated capacitive touch screen and a manufacturing method of the novel ITO gap-bridge integrated capacitive touch screen. The novel ITO gap-bridge integrated capacitive touch screen comprises a transparent baseplate as well as a silicon dioxide layer, a niobium pentoxide layer, a black resin layer, an ITO gas-bridge electrode, a first insulating layer, an ITO electrode, a metal electrode and a second insulating layer which are sequentially stacked on the transparent baseplate; wherein the silicon dioxide layer is covered overall by glass, and the niobium pentoxide layer is covered overall by the silicon dioxide layer; the ITO electrode comprises a capacitive screen drive and a sensing electrode and is provided with the structure of regular graphics; the capacitive screen drive and the sensing electrode are in the identical layer, mutually independent and insulating from each other and are vertically designed. Due to the reasonable design of the stacked structure of the capacitive touch screen and the bridging conduction mode, the transmissivity of the capacitive touch screen is improved effectively, the visuality of the ITO pattern is reduced, and the 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 an ITO bridge 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 b...
