Embodiment Construction

[0011] Such as figure 1 As shown, the present invention provides a capacitive screen functional sheet with double-sided metal wiring, including a glass substrate 1, and the top surface of the glass substrate 1 is sequentially provided with an upper shadow elimination layer 2a, an upper metal wiring layer 3a and a top elimination layer. The shadow layer 4a, the bottom surface of the glass substrate 1 is sequentially provided with the lower shadow erasing layer 2b, the lower metal wiring layer 3b and the bottom shadow erasing layer 4b, and the upper metal wiring layer 3a and the lower metal wiring layer 3b are both integral Surface metal wiring, the impedance of the upper shadow erasing layer 2a matches the upper metal wiring layer 3a, and the lower shadow erasing layer 2b matches the impedance of the lower metal wiring layer 3b.

[0012] During specific manufacturing, the glass substrate 1 can adopt conventional functional glass, and the operating parameters of the upper shadow...

Abstract

The invention discloses a double-sided metal wired capacitive screen functional plate comprising a glass substrate, wherein the top surface of the glass substrate is sequentially provided with an upper shadow eliminating layer, an upper metal wiring layer and a top shadow eliminating layer from the top down; the bottom surface of the glass substrate is sequentially provided with a lower shadow eliminating layer, a lower metal wiring layer and a bottom shadow eliminating layer from the top down; metal wiring is performed on the whole surfaces of both the upper and lower metal wiring layers, the impedance of the upper shadow eliminating layer is matched with that of the upper metal wiring layer, and the impedance of lower upper shadow eliminating layer is matched with that of the lower metal wiring layer. According to the double-sided metal wired capacitive screen functional plate provided by the invention, a traditional ITO wiring mode is abandoned, and double-sided metal wiring is used, so that conductive performance of the functional plate is greatly improved; transmittance of the functional plate is enhanced by using the shadow eliminating layers matched with metal wiring, so that metal wiring traces are not significant, a metal circuit shape is not prone to appear on the appearance of the plate; and in addition, ITO coating and ITO yellow light technologies are not needed during manufacturing, so that cost and production time of products are saved, efficiency is improved, productivity is increased, and production value is enhanced.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a capacitive screen functional sheet with double-sided metal wiring. Background technique [0002] With the increasing number of multimedia devices, smart electronic devices such as mobile phones and tablet computers can be seen everywhere in our lives. Most of these devices use touch screens as tools for collecting and identifying information. more and more widely applied. [0003] At present, the application of capacitive touch screen is the most common, and the capacitive touch screen with double-layer glass structure has the advantages of supporting real multi-point, high accuracy, high light transmission, and good handwriting effect compared with single-layer glass structure. The double-layer glass structure generally includes a cover plate and a functional sheet, and its touch function is realized on the functional sheet. [0004] At this stage, the in-plane traces ...
