Abstract
Disclosed herein are a touch display device capable of solving distortion of a display image due to a difference in condition between touch nodes, and a method of driving the same. The touch display device includes a panel driver configured to drive gate lines and data lines of a panel and drive and sense touch electrodes, a timing controller configured to control an operation of the panel driver, and a touch controller configured to control touch electrode driving and a sensing operation of the panel driver, wherein the timing controller compensates a display signal for a difference in condition between a touch node where a touch occurs and a touch node where a touch does not occur or a difference in physical structure between the touch nodes.
