HYBRID SENSING TOUCHSCREEN APPARATUS AND METHOD OF DRIVING THE SAME
First Claim
1. A touchscreen apparatus comprising:
- 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 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 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.

16. A method of driving a touchscreen apparatus, the method comprising:
-
activating a first pixel row including pixels; activating one of a light-sensing unit for sensing incident light and a touch-sensing unit for sensing a physical touch, the light-sensing unit and the touch-sensing unit being adjacent to the first pixel row, and resetting the other of the light-sensing unit and the touch-sensing unit; resetting the activated one of the light-sensing unit and the touch-sensing unit and activating the reset other of the light-sensing unit and the touch-sensing unit; and activating a second pixel row including additional pixels, the second pixel row being adjacent to the light-sensing unit and the touch-sensing unit, applying a common voltage to the pixels when the first and second pixel rows are in an activated state, and prohibit providing the common voltage to the pixels when the light-sensing unit or the touch-sensing unit is in an activated state. - View Dependent Claims (17, 18, 19, 20)
