Abstract
A touch driving circuit and a touch display device are disclosed. A plurality of channel switches for driving touch electrodes disposed in areas disposed symmetrically to each other may be simultaneously turned on to perform touch sensing in a state in which a plurality of touch lines electrically connected to the plurality of channel switches are short-circuited to each other. Accordingly, touch sensing may be performed using touch data in which a load deviation due to the touch lines according to areas in which the touch electrodes are disposed is reduced, thereby improving the performance of the touch sensing.
