Abstract
The present embodiments may provide a touch display device including: a display panel in which a plurality of data lines, a plurality of gate lines, and a plurality of touch electrodes are disposed; a gate-driving circuit configured to drive the plurality of gate lines; a data-driving circuit configured to drive the plurality of data lines; and a touch-driving circuit configured to drive the plurality of touch electrodes while the plurality of data lines and the plurality of gate lines are driven. In this touch display device, while a touch-driving signal swings with a predetermined amplitude, a data signal and a gate signal may also swing with the predetermined amplitude. According to the present embodiments, it is possible to enable high-speed image display and high-speed touch sensing, to perform a display operation and a touch operation simultaneously, and to display an image normally without any image change.
