Abstract: A system may include a display driven using display driving circuitry to present an image via pixels. The display driving circuitry may include a sensor core compatible with one or more strain sensing circuits. The same sensor core may be used by a control system of the display to sense a stress applied to a strained region of a display using a current divider sensing circuit and/or a Wheatstone bridge sensing circuit.
