Abstract
The present disclosure provides a touch driving circuit for providing driving signals to touch driving electrodes of a touch panel in a touch phase. The touch driving circuit includes a plurality of cascaded touch shift register units. The number of the touch shift register units is same as the number of columns of the touch driving electrodes. The touch driving circuit further includes a plurality of switching units corresponding to the plurality of touch shift register units. The switching unit includes a driving signal input terminal, a control terminal and a driving signal output terminal. When the touch shift register unit outputs a high level signal, the switching unit connects the driving signal input terminal and the driving signal output terminal. Correspondingly, the present disclosure further provides a display device and a driving method thereof.
