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

Disclosed are an ITO through hole capacitive touch screen and a manufacturing method therefor. The ITO through hole capacitive touch screen comprises a decorative glass substrate, a capacitive functional substrate stacked on the decorative glass substrate via an optical glue, and, sequentially stacked on the capacitive functional substrate, an ITO electrode, a first insulation layer, an ITO through hole electrode, a metal electrode, and a second insulation layer. The ITO electrode comprises a capacitive screen driver (ITO electrode 1) and a sensing electrode (ITO electrode 2), and is provided with a patterned graphic design. ITO electrode 1 and ITO electrode 2 are on a same layer, and are mutually independent, mutually insulated, and vertical in design. The present invention uses for the capacitive touch screen the stacked structure and an ITO conduction scheme to perform a logical design, and employs the ITO through hole scheme to conduct up and down the ITO signal electrodes, thus allowing for the capacitive touch screen effectively improved transmittance, operational stability, and sensitivity to touch.

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...
