Abstract: In a method of driving a display device and a driving circuit using the driving method, when a current needed to display an image corresponding to one frame is calculated based on a data signal, a second vertical start signal delayed by a first time interval more than a first vertical start signal based on the calculated current. A first gate signal is sequentially output in response to the first vertical start signal, and a display data voltage obtained from the data signal is output during a high period of the first gate signal. A second gate signal is sequentially output in response to the second vertical start signal, and a black data voltage is output during a high period of a second gate signal. Thus, the current applied to a display part is controlled, thereby reducing power consumption and improving moving image.
