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.
