Touch display apparatus and method of manufacturing the same

A method of manufacturing a touch display apparatus, the method comprising:

• forming a display panel including a display region and a peripheral region, the display panel configured to display an image;
• forming a touch electrode and a first pressure sensing electrode on the display panel;
• forming a polarizer on the touch electrode and the first pressure sensing electrode, the polarizer including a dielectric elastomer material;
• and
• forming a second pressure sensing electrode on the polarizer, the polarizer being disposed, in a direction normal to a surface of the display panel, between the second pressure sensing electrode and the first pressure sensing electrode,
• wherein the touch electrode is disposed on the display region of the display panel, the touch electrode comprises a plurality of touch patterns, and
• wherein the first pressure sensing electrode is disposed on the peripheral region of the display panel.

A method of operating a touch display apparatus, the method comprising:

• displaying an image via a display panel of the touch display apparatus, the display panel comprising a display region and a peripheral region, the touch display apparatus further comprising:
• a touch electrode disposed on the display region, the touch electrode being configured to detect a position of a touch interaction;
• a first pressure sensing electrode disposed on the peripheral region;
• a second pressure sensing electrode disposed on the display panel;
• a polarizer disposed, in a direction normal to a surface of the display panel, between the second pressure sensing electrode and the first pressure sensing electrode;
• and
• a sensing driver configured to generate driving signals, the sensing driver being connected to the touch electrode and the pressure sensing electrode;
• applying, via the sensing driver, a same driving signal to the touch electrode and the pressure sensing electrode;
• and
• detecting the position and a pressure of the touch interaction in accordance with the application of the same driving signal.
