Problems solved by technology

[0009] 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

Embodiment Construction

[0057] The present invention will be described in further detail below in conjunction with specific embodiments.

[0058] Such as figure 1 and figure 2 As shown, the ITO through-hole capacitive touch screen includes a chemically strengthened glass substrate 11 with a thickness of 0.5 to 2.0 mm, which is sequentially laminated on a black resin layer 12 of a transparent glass substrate, an ITO electrode 13, a first insulating layer 14, and an ITO through-hole. Aperture electrode 15, metal electrode 16 and second insulating layer 17; Described ITO electrode 13 comprises capacitive screen drive (ITO electrode 1) 42 and induction electrode (ITO electrode 2) 43, has regular figure structure; ITO electrode 1 and ITO The electrodes 2 are on the same level, independent of each other, insulated from each other, and designed vertically. The strengthened glass substrate 11 includes a window area 21 and a non-window area 22 , the black resin layer 12 is distributed in the non-window are...

Abstract

Disclosed are a metal crossover single-body capacitive touch screen and a manufacturing method therefor. The metal crossover capacitive touch screen comprises a transparent substrate, and, sequentially stacked on the transparent substrate, a black resin layer, an ITO electrode, a first insulation layer, a metal electrode, a metal crossover, and a second insulation layer. The ITO electrode comprises a capacitive screen driver and a sensing electrode, and is provided with a patterned graphic structure. The capacitive screen driver and the sensing electrode are on a same layer, and are mutually independent, mutually insulated, and vertical in design. The transparent substrate comprises a window region and a non-window region. The black resin layer is distributed in the non-window region of a display screen. The present invention uses for the capacitive touch screen the stacked structure and a crossover conduction scheme to perform a logical design, thus allowing for the capacitive touch screen effectively improved reliability, operational stability, and sensitivity to touch.

Description

[0001] technical field [0002] 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 [0003] 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...
