Zusammenfassung: | Embodiments of the disclosure relate to a touch driving circuit and a touch display device. There may be provided a touch driving circuit capable of attenuating noise in the touch sensing signal and enhancing the output signal by the integrator by transferring charge through a sample-and-hold driving path and a bypass driving path, inverting the polarity of the charge sampled by the sampling switching block, and increasing the number of times of sampling. Further, as the amount of charge transferred by the offset voltage control switch included in the sample-and-hold driving path and bypass driving path may be adjusted within an offset voltage range, the performance of touch sensing may be enhanced. |
