Abstract

A touch display panel includes a display module, a polarizer, a first touch electrode structure and a second touch electrode structure. The display module has a substrate. The polarizer is disposed opposite to the display module. The first touch electrode structure and the second touch electrode structure are electrically insulated to each other and are disposed between the polarizer and the substrate of the display module.

Claims

1. A touch display panel, comprising:

a display module having a substrate;

a polarizer disposed opposite to the display module;

a first touch electrode structure; and

a second touch electrode structure, wherein the first touch electrode structure and the second touch electrode structure are electrically insulated to each other and are disposed between the polarizer and the substrate of the display module.

2. The touch display panel of claim 1, wherein the first touch electrode structure is disposed on the polarizer, and the second touch electrode structure is disposed on the substrate.

3. The touch display panel of claim 1, further comprising a transparent substrate disposed between the display module and the polarizer.

4. The touch display panel of claim 3, wherein the first touch electrode structure is disposed on the transparent substrate, the second touch electrode structure is disposed on the substrate, and the first touch electrode structure and the second touch electrode structure are located between the transparent substrate and the display module.

5. The touch display panel of claim 3, wherein the first touch electrode structure is disposed on the polarizer, the second touch electrode structure is disposed on the substrate, and the transparent substrate is located between the first touch electrode structure and the second touch electrode structure.

6. The touch display panel of claim 3, wherein the first touch electrode structure is disposed on the polarizer and is located between the polarizer and the transparent substrate.

7. The touch display panel of claim 6, wherein the second touch electrode structure is disposed on the transparent substrate and is located between the transparent substrate and the substrate.

8. The touch display panel of claim 6, wherein the second touch electrode structure is disposed on the transparent substrate and is located between the polarizer and the transparent substrate.

9. The touch display panel of claim 1, wherein at least one of the first touch electrode structure and the second touch electrode structure comprises a metal nanowire, a transparent conductive film or a metal mesh.

10. The touch display panel of claim 3, wherein at least a shielding layer is disposed on the transparent substrate, and the shielding layer is located at the periphery area of the transparent substrate.

11. The touch display panel of claim 1, wherein at least a shielding layer is disposed on the polarizer, and the shielding layer is located at the periphery area of the polarizer.

12. The touch display panel of claim 2, wherein an adhesive layer is disposed between the first touch electrode structure ant the second touch electrode structure.

13. The touch display panel of claim 7, wherein an adhesive layer is disposed between the transparent substrate and the substrate.

14. The touch display panel of claim 8, wherein an adhesive layer is disposed between the transparent substrate and the substrate.
