Abstract:
1. A method of driving a display array, the display array including a plurality of pixel circuits, each pixel circuit including a driving transistor, at least one switch transistor, a storage capacitor and an organic light emitting device, the method comprising the steps of: applying a current or voltage to the organic light emitting device; monitoring a current or voltage flowing through the organic light emitting device; predicting a shift in the voltage of the organic light emitting device, based on the monitored current or voltage and determining the state of the pixel circuit, the predicting including estimating an intermediate voltage of the organic light emitting diode, wherein the estimating includes adjusting the intermediate voltage based on a resolution of a driver circuit coupled to the driving transistor and increasing the intermediate voltage by the resolution of the driver circuit responsive to an actual voltage shift being larger than the intermediate voltage; and providing, to the organic light emitting device, a bias associated with the shift in the voltage of the organic light emitting device.
