摘要
A touch display device includes a touch panel on which a plurality of touch electrodes is disposed; and a touch circuit configured to output a touch driving signal of a pulse type to the touch panel and to sense occurrence of touch or a touch position according to a touch synchronization signal for defining a touch period, wherein the touch circuit comprises: a touch driver configured to supply the touch driving signal to one or more of the plurality of touch electrodes to drive the touch electrodes in the touch period and to obtain sensing data by signal processing of a touch sensing signal detected from the driven touch electrodes; and a touch controller configured to receive the sensing data to sense occurrence of touch or a touch position and to determine whether the touch driver malfunctions, and to output a simplified initialization command to the touch driver when it is determined that the touch driver malfunctions, and the touch driver is initialized with a pre-stored set value maintained not changed upon receiving the simplified initialization command.
