Abstract

A touch screen panel is provided. The touch screen panel includes an Indium Tin Oxide (ITO) sensor glass layer, a window glass layer mounted above the ITO sensor glass layer by means of an Optical Clear Adhesive (OCA), a conductive layer disposed between a surface of the window glass layer and a surface of the ITO sensor glass layer that includes an electrode pattern, and a touch screen control unit mounted on one of the window glass layer surface and the ITO sensor glass layer surface on which the conductive layer is mounted.

Claims

1. A touch screen panel comprising:

a window glass layer;

a conductive layer laminated below the window glass layer, the conductive layer including an electrode pattern for sensing a touch;

a touch screen control unit mounted on a lower surface of the window glass layer; and

a Flexible Printed Circuit (FPC) mounted to a lower surface of the window glass layer and protruding from the end portion of the conductive layer, the FPC including a connection member on an end portion thereof protruding from the end portion of the conductive layer, the connection member electrically connected to a circuit board,

wherein the touch screen control unit is a control unit for controlling a touch screen.

2. The touch screen panel of claim 1, wherein the touch screen control unit is implemented with a Tape Carrier Package (TCP) that includes a plurality of integrated circuits.

3. The touch screen panel of claim 2, wherein the TCP is bonded with an Anisotropic Conductive Film (ACF) by using Tape Automated Bonding (TAB).

4. The touch screen panel of claim 2, wherein the Flexible Printed Circuit (FPC) is bonded to the end portion of the conductive layer by using an Anisotropic Conductive Film (ACF).

5. The touch screen panel of claim 1, wherein the touch screen panel does not include an additional Indium Tin Oxide (ITO) layer.

6. The touch screen panel of claim 1, wherein an oxidation protection coating layer is coated on an exposed portion of the conductive layer.

7. The touch screen panel of claim 1, wherein the conductive layer is comprised of a transparent conductive material.

8. The touch screen panel of claim 1, wherein the electrode pattern comprises a silver paste electrode portion arranged at one end of the conductive layer and connected the the FPC.
