Abstract
The present invention discloses a touch panel structure formed by an anti-scratch surface layer and a capacitive sensor layer, and a transparent lamination layer is used for pasting the two into a panel. The capacitive sensor layer includes an X-axis first transparent conductive layer and a Y-axis second transparent conductive layer formed on both sides of a transparent plastic carrier to provide a touch panel structure having the advantages of a relatively low material cost, a light weight, an easy manufacturing and molding, a better lamination yield and a flexible and break-free feature.
Claims7
A touch panel structure, consisting essentially of:
- an anti-scratch surface layer made of a tempered transparent plastic film;
- a first and a second transparent lamination layers;
- a capacitive sensor layer, comprising:
- a plastic substrate adhered to a bottom of the anti-scratch surface layer via the first transparent lamination layer,
- an X-axis first transparent conductive layer deposited on a bottom of the plastic substrate,
- a Y-axis second transparent conductive layer adhered on a bottom of the X-axis first transparent conductive layer via the second transparent lamination layer,
- a transparent plastic carrier separate from the plastic substrate wherein the Y-axis second transparent conductive layer is formed on a top surface of the transparent plastic carrier and wherein the two X-axis and Y-axis transparent conductive layers each comprise respectively:
- a plurality of X-axes first sense elements:
- and
- a plurality of Y-axes first sense elements alternately arranged in an array form, such that each sense element in a respective X or Y axis is connected electrically and each sense element in another axis is insulated therefrom;
- and
- a conductive layer, directly formed at a bottom of the transparent plastic carrier for providing an EMI shielding function.
