Abstract

A pixel circuit of a display device, an organic light emitting display device and a method for driving the same are discussed. The pixel circuit of the display device in one example includes an organic light emitting device emitting light through a current; a driving transistor controlling the current flowing in the organic light emitting device; a first capacitor connected between gate and source electrodes of the driving transistor; a second capacitor in which a data voltage is previously stored; and a switching unit charging the data voltage, which is stored in the second capacitor, in the first capacitor, and allowing the organic light emitting device to emit light by driving the driving transistor in accordance with the data voltage charged in the first capacitor and at the same time charging a data voltage of next frame in the second capacitor.
