Abstract
A touch display device configured to drive a signal line in a first plurality of steps during a line-sensing period and adjust an offset capacitance in a second plurality of steps corresponding to the first plurality of steps.
Claims21
A touch display device configured to drive a signal line in a first plurality of steps during a line-sensing period and adjust an offset capacitance in a second plurality of steps corresponding to the first plurality of steps.
A touch display device, comprising:
- a touch screen panel including a gate line extended in a first direction and a data line extended in a second direction;
- and
- a touch screen sensor block configured to control the touch screen panel, and detect a touch position with a capacitance detected using the gate line and the data line as line sensors,
- wherein an offset capacitance of the touch screen panel is compensated in a first plurality of steps using a plurality of offset capacitance control switches.
