Description

A kind of multi-functional projected capacitive contact panel

Technical field

The utility model relates to the capacitance touching control field, is specifically related to a kind of multi-functional projected capacitive contact panel.

Background technology

After iPhone started the touch-controlling interface revolution, hommization contact panel technology was diffused to IT and the consumer electronics field such as handheld device, computer all-in-one machine, multimedia television just gradually by mobile phone.Contact panel will be one of following most important operating and controlling interface development trend.The touch-screen that existing condenser type product proposes is to adopt the DITO structure, and the basis that forms the columns and rows trace on the two sides of basic unit is made into the capacitive touch sensing plate.

Prior art is to form the induction line layer on same substrate two sides, because born processing procedure problem yield can't promote, large-sized product particularly is more than 15 inches in the production run.Production cost is large, and waste of material is large.

Existing contact panel, human body contact induction face is glass mostly, PET or PMMA, touch feeling have the sensation that significantly has some setbacks, particularly large-sized product.

The contact panel that prior art is produced, if be applied on all-in-one or the multimedia television, external shock resistance ability is more weak, and is easily damaged.

The utility model content

The purpose of this utility model is to be for the deficiencies in the prior art, a kind of multi-functional projected capacitive contact panel is provided, the touch-control structure that it provides has more manufacturability, large scale product more than 15 inches particularly, the relatively high waste of material of yield reduces, sensation in the time of simultaneously can improving the human body touch inductive layer is more sliding suitable, adopts the three-decker external shock resistance ability obviously to promote.

According to an aspect of the present utility model, a kind of multi-functional projected capacitive contact panel is provided, comprising: three substrates, enclosing cover touches substrate, drives substrate, induction feedback substrate.The enclosing cover of the superiors touches substrate, and the driving substrate in middle layer and undermost induction feedback substrate adopt the bonding one of optical cement on three laminar substrates.

The superiors' enclosing cover touches substrate, with tempered glass as substrate, upper surface spraying or a kind of transparent material of etching at glass substrate, in order to increase the roughness of glass substrate upper surface, reach the effect that improves touch perception and anti-outdoor high light, then make frame according to customer requirement with the mode of silk-screen or spraying in lower glass surface, can arrange in pairs or groups black white of frame waits shades of colour and profile.

The middle layer drives substrate; adopt PET or PMMA flexible base, board or glass substrate; the conducting film that homogeneous transparent is arranged in the above; successively the method by silk-screen, etching or gluing photoetching forms rhombus strip electrically conducting transparent circuit with nesa coating on conducting film; side at whole electrically conducting transparent circuit is guided to side by certain technique formation circuit with the electrically conducting transparent circuit with the high conductive material of the conductances such as silver; with flexible PCB drive plate is connected with controller again, on circuit, will be coated with layer of transparent insulating material holding circuit simultaneously.

Bottom induction feedback substrate adopts glass substrate, and the conducting film of homogeneous transparent is arranged in the above, and successively the method by silk-screen, etching or gluing photoetching forms rhombus strip electrically conducting transparent circuit with nesa coating on conducting film.Conducting wire direction and the driver circuit perpendicular direction that drives substrate; side forms circuit with the high conductive material of the conductances such as silver by certain technique the electrically conducting transparent circuit is guided to side; with flexible PCB drive plate is connected with controller again, on circuit, will be coated with layer of transparent insulating material holding circuit simultaneously.

Adopt optical cement first the driving substrate in middle layer to be in the same place with undermost induction feedback baseplate-laminating, and then coat optical cement at the outside surface that drives substrate, utilize optical cement that enclosing cover is touched baseplate-laminating at the outside surface that drives substrate, such three laminar substrates are just fitted and have been superimposed.

Adopt multi-functional projected capacitive contact panel of the present utility model, the touch-control structure that it provides has more manufacturability, large scale product more than 15 inches particularly, the relatively high waste of material of yield reduces, sensation in the time of simultaneously can improving the human body touch inductive layer is more sliding suitable, adopts the three-decker external shock resistance ability obviously to promote.
