Abstract:
1. An organic light emitting display device comprising: a panel driver; and a display panel including a plurality of pixels, each of the plurality of pixels having a pixel circuit that has a driving transistor, a first driving voltage terminal connected to the driving transistor, a light emitting element, a second driving voltage terminal connected to the light emitting element, and a capacitor connected between a gate and source electrode of the driving transistor, wherein the panel driver is configured to drive the pixel circuit in: the panel driver being configured to supply the data voltage and the reference voltage to the plurality of pixels at the data charging period, and configured to simultaneously change a level of the first driving voltage or the second driving voltage supplied to the plurality of pixels via the first driving voltage terminal and the second driving voltage terminal, respectively, at the data charging period.
