Abstract:
A touchscreen apparatus includes pixel rows including pixels configured to display an image, a touch-sensing unit configured to sense a physical touch, light-sensing unit configured to sense incident light, a first sensor gate line configured to provide a first gate signal for activating the light-sensing unit and resetting the touch-sensing unit, a second sensor gate line configured to provide a second gate signal for activating the touch-sensing unit and resetting the light-sensing unit, and a reset circuit configured to provide a common voltage to the pixels based on the operation of at least one of the light-sensing unit and the touch-sensing unit.
