Abstract
A display device integrated with touch function and a driving method thereof, the display device comprising: a display unit (); a touch detection circuit () configured to conduct touch detection, and generate a plurality of touch detection signals; and a driving unit () configured to simultaneously driving a data refresh of the display unit () and the touch detection of the touch detection circuit (), wherein region for data refresh and region for touch detection do not overlap at the same time period. The present disclosure prolongs the charging time for the display pixels and solves the problem of insufficient charging time of the integrated touch high resolution display device by a simultaneous touch and the display driving. In the meantime, by incorporating a reference unit, a reference voltage which is not affected by touching and can reflect in real time the signal interferences caused by display driving (namely, data refresh) is obtained.
