Abstract:
A display device including a touch screen and a driving circuit of the display device are disclosed. A display panel of the display device is driven while being divided into a first block, to which data is applied during a first display period, and a second block, to which data is applied during a second display period following a touch sensing period. A display driving circuit includes an (N−1)th stage driving a last gate line of the first block and an Nth stage driving a first gate line of the second block. The Nth stage includes a charger charging a Q node of the Nth stage in the touch sensing period in response to a multi-start signal before the second display period starts.
