Simultaneous programming and emission driving using external compensation method for 3D active matrix organic light emitting diode (AMOLED) displays is proposed. The emission current uniformity is improved by compensating threshold voltage and mobility variations of driving TFTs. Simulation results show that the maximum emission current error range of the proposed method is from −1.6% to 0.6% in 40‐inch full HDTV condition when the threshold voltage of driving TFT variation is form −1 V to 1 V and mobility variation of driving TFT is from −10% to 10%. The emission and programming time of 3D AMOLED display is also increased by simultaneous driving method.
