Structural improvement for digital capacitance touch pad

Abstract

The invention provides structural improvement for a digital capacitance touch pad. The touch pad is composed of a scratch-resistant surface layer and a capacitance inductive layer framework which are adhered into a plate body through a transparent cementing layer, wherein the scratch-resistant surface layer can be a transparent plastic film after surface-hardening treatment; each capacitance inductive layer is respectively provided with a first transparent conductive layer in an X axial direction and a second transparent conductive layer in a Y axial direction at two sides of a transparent plastic carrier; and the two capacitance inductive layers are respectively designed along a plurality of the X axial directions and a plurality of the Y axial directions which are in a cross arrangementin a matrix form so that inductive units in one axial direction are in electrical connection, and inductive units in the other axial direction are in an insulation arrangement. The improved touch padstructure has relatively lowered material cost, light weight, easy machining and molding, better binding yield and flexibility, and has small possibility of rupture.

Description

technical field [0001] The present invention relates to a new molding structure of a touch panel, and aims to provide a touch panel structure that is relatively low in material cost, light in weight, easy to process and shape, has better bonding yield, and is soft and not easy to break. Background technique [0002] Press, touch panels can be divided into resistive, capacitive, sonic, light-guided wave, load-changing, etc. according to different action methods, but among them, resistive and capacitive touch panels are the most widely used; among them, The resistive touch panel is composed of an upper transparent conductive plastic film and a lower transparent conductive carrier, separated by a plurality of insulating spacers in the middle, and a voltage of 5V is passed between the upper transparent conductive plastic film and the lower transparent conductive carrier. Fingers or stylus touch the upper transparent conductive plastic film to form a depression and then contact t...

Problems solved by technology

[0006] However, the image 3 The structure of the conventional touch panel shown tends to be complicated, and the relative material and processing costs are relatively high, and the capacitive sensing layers of the transparent conductive plastic films 141, 142 are completed by traditional screen printing and etching processes, and the accuracy of the capacitive sensing patterns is relatively high. In addition, the anti-scratch layer 11 is also made of glass, so there is still a poor bonding yield, high cost and the risk of fragmentation, and the touch panel is composed of a multi-layer sensing layer and an insulating layer. Not only the board body is thicker, but also seriously detracts from the light transmittance of the touch panel
