Abstract: A timing controller according to one aspect of the present disclosure that is capable of operating in a low-power mode for a touch sensor driving period includes a receiver which receives a timing synchronization signal and video image data from an external source, a data processor which generates a gate control signal and a data control signal on the basis of the timing synchronization signal and arranges the video image data as pixel data for a display panel, and a transmitter which operates in a normal mode to output the pixel data, the gate control signal, and the data control signal for a display driving period and operates in a low-power mode for at least some time of a touch sensor driving period.

Abstract: Disclosed herein is a touch display device including a panel driver configured to drive gate lines and data lines of a panel and drive and sense touch electrodes, and a timing controller configured to control a drive timing and an output of the panel driver, wherein the timing controller time-divisionally drives each frame period into a plurality of display operation periods and a plurality of touch operation periods such that each display operation period and each touch operation period alternate and, during at least one compensation period of a first compensation period adjacent to an immediately preceding touch operation period and a second compensation period adjacent to an immediately following touch operation period in each display operation period, compensates at least one of a data signal and a gate signal, which is to be supplied to a compensation area, according to a variation in state of a panel.
