Abstract
The present disclosure provides a touch display device comprising first and second subpixels included in adjacent first and second pixel areas in a column direction, first and second touch sensors respectively adjacent to the first and second pixel areas in a row direction, a first touch line electrically connected to the first and second touch sensors and extending in the column direction, a first sensing line extending in the column direction, a first sensing transistor configured to control an electrical connection between the first sensing line and the first touch sensor, a second sensing transistor configured to control electrical connection between the first sensing line and the second touch sensor, and a common touch bridge electrically connecting the first touch sensor and the second touch sensor to the first touch line. The touch display device can perform more accurate touch sensing by removing a ghost touch that may be caused by a temperature effect. In addition, the touch display device may reduce parasitic capacitance and load related to the touch sensor structure.
