Abstract: A system and method for input sensing comprises a display device having at least one piezoresistive sensing transistor. During a first period, a first resulting signal is received with a first data line by driving a first piezoresistive sensing transistor of a first subpixel of the display device with a first select signal. The first resulting signal corresponds to a change in resistance of the first piezoresistive sensing transistor. Further, at least one of force information and positional information associated with an input object may be determined at least partially based on the change in resistance.
