Abstract
A touch display device and a method of driving the same. A transition value due to polarity inversion of a data voltage supplied to a predetermined number of adjacent subpixels is reduced by varying an inversion pattern by analysis of image data, so that fluctuations in the voltage of touch electrodes due to the transition of the data voltage are minimized. Accordingly, noise due to fluctuations in the voltage of the touch electrodes is removed so as to improve the performance of touch sensing performed in a period in which display driving is performed.
