Force sensing in a touch display

Abstract:

Embodiments described herein include a display device that includes a display substrate coupled to a frame. A stiffener substrate is also coupled to the frame. A first force sensing element is disposed on the stiffener substrate, and the stiffener substrate is disposed between the first force sensing element and the display substrate. The display device also includes a second force sensing element, where a distance between the first force sensing element and the second force sensing element decreases when the display substrate is deflected.
