Abstract: Embodiments of the present disclosure relate to a touch display device, a driving method, and a driving circuit. More particularly, embodiments of the present disclosure relate to a touch display device, a driving method, and a driving circuit capable of preventing touch sensitivity from being affected by display driving even though simultaneously performing the display driving and touch driving by supplying a data voltage to a plurality of data lines disposed in a display panel, supplying a common voltage to a plurality of common electrodes disposed in the display panel, displaying an image through the display panel, and supplying a common voltage to the common electrodes.

Abstract: A touch display device, a display controller, a driving circuit, and a driving method. Even in the case that a rate (or an input cycle) at which an image supply device supplies image data is not synchronized with a rate (or a beacon cycle) at which a beacon signal for pen sensing is output to the display panel, display processing and touch sensing (e.g., pen sensing or finger sensing) is performed ordinarily by controlling data output processing.
