    摘要： An touchscreen apparatus includes pixel rows including pixels configured to display an image, a touch-sensing unit configured to sense a physical touch and a light-sensing unit configured to sense incident light, the touch-sensing unit and the light-sensing unit being between two adjacent pixel rows and configured to operate based on first and second gate signals, a first sensor gate line (SGLn) connected to the light-sensing unit and the touch-sensing unit and configured to provide the first gate for activating the light-sensing unit and resetting the touch-sensing unit, a second sensor gate line (SGLn+1) connected to both the light-sensing unit and the touch-sensing unit and configured to provide the 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.
