Abstract

A touch display apparatus is disclosed. The touch display apparatus includes an electrophoretic structure, a protective layer and at least one touch sensing layer. The protective layer is disposed on the electrophoretic structure. The touch sensing layer is disposed on the protective layer and takes the protective layer as a carrier.

First claim

What is claimed is:

1. A method for manufacturing a touch display apparatus, comprising;
forming a touch sensing layer on a protective layer on an electrophoretic structure, wherein forming the touch sensing layer on the protective layer comprises;
providing a thin film substrate;
forming a sensing electrode layer on the thin film substrate; and
adhering the thin film substrate onto the protective layer; and

disposing a flexible circuit board on the sensing electrode layer and electrically connecting the flexible circuit board and the sensing electrode layer at an operation temperature, wherein the operation temperature ranges from 120° C. to 150° C.

2. The method of claim 1 , wherein the flexible circuit board is disposed on the sensing electrode layer before the thin film substrate is adhered onto the protective layer.

3. The method of claim 1 , wherein the flexible circuit board is disposed on the sensing electrode layer after the thin film substrate is adhered onto the protective layer.

4. The method of claim 1 , further comprising placing a light guide plate over the touch sensing layer to cover the touch sensing layer.

5. The method of claim 1 , further comprising forming a thin film transistor (TFT) array in direct contact with the electrophoretic structure.

6. The method of claim 1 , further comprising forming a shielding layer between the electrophoretic structure and the protective layer.

7. The method of claim 1 , wherein the electrophoretic structure includes a plurality of microcapsules, and each of the plurality of microcapsules has a plurality of light-colored charged particles and a plurality of dark-colored charged parties.

8. The method of claim 7 , wherein the plurality of light-colored charged particles and the plurality of dark-colored charged parties have charges of different types.

9. The method of claim 1 , wherein a material of the protective layer comprises polymethylmethacrylate (PMMA), polycarbonate (PC), polyvinyl chloride (PVC) or polyethylene terephthalate (PET).

10. The method of claim 1 , wherein a material of the thin film substrate comprises polymethylmethacrylate (PMMA), polycarbonate (PC), polyvinyl chloride (PVC) or polyethylene terephthalate (PET).

11. The method of claim 1 , wherein the sensing electrode layer comprises a light permeable material or a plurality of nano metal wires therein.

12. The method of claim 1 , wherein a thickness of the touch sensing layer is less than 0.06 mm.

13. The method of claim 6 , wherein a material of the shielding layer comprises a conductive material.
