Abstract

A touch control panel comprises a transparent substrate, a contact layer, a first transparent electrode formed over the transparent substrate and a second transparent electrode formed over the contact layer facing the first transparent electrode. The space between the first transparent electrode and the second transparent electrode contains a plurality of spacers. The transparent substrate or the contact layer or both have ultra-violet ray shielding capability.

Claims

1. A display device structure, comprising:

a display panel, wherein the display panel is selected from the group consisting of an organic light-emitting diode panel, a plasma display panel, a liquid crystal display panel and a cathode ray tube screen display; and

a touch control panel over the display panel, the touch control panel comprising

a transparent substrate;

a first transparent electrode disposed on the transparent substrate;

a contact layer over the transparent substrate; and

a second transparent electrode disposed on surface of the contact layer facing the first transparent electrode,

wherein at least the transparent substrate and the contact layer are capable of resisting ultra-violet rays such that intensity of the ultra-violet rays after passing through the touch control panel is substantially reduced, and wherein material constituting the contact layer is selected from the group consisting of polymer resin, polyester, glass, and glass with a transparent electrode therein.

2. The display device structure of claim 1, wherein the contact layer further includes an ultra-violet ray resisting layer for shielding or absorbing ultra-violet rays.

3. The display device structure of claim 1, wherein the contact layer and the transparent substrate comprise an optical coating thereon.

4. The display device structure of claim 1, wherein the touch control panel further includes an adhesion element attached to the edges of the first transparent electrode.

5. The display device structure of claim 1, wherein the touch control panel further includes a hard coating on the outward facing surface of the contact layer.

6. The display device structure of claim 1, wherein the space between the first transparent electrode and the second transparent electrode comprise a plurality of spacers.

7. The display device structure of claim 1, wherein both the transparent substrate and the contact layer of the touch control panel have ultra-violet ray resisting capability.

8. The display device structure of claim 1, wherein the first transparent electrode and the second transparent electrode of the touch control panel is made from identical material or different materials.

9. The display device structure of claim 1, wherein the touch control panel is attached to the display panel through double-sided tape.
