In this paper, an active‐matrix organic light emitting diode (AMOLED) pixel circuit is proposed for 1000 ppi and 5.87‐inch mobile displays with augmented and virtual reality applications. The proposed pixel circuit consisting of 3 thin‐film transistors (TFTs) and 2 capacitors employs a simultaneous emission driving method to reduce the number of TFTs. The simulation results of the proposed pixel circuit showed that the emission current errors caused by the threshold voltage variation of driving TFT and crosstalk error were less than ±0.4 LSB and ±1 LSB, respectively, over the entire gray level. Therefore, the proposed pixel circuit is highly suitable for AMOLED displays.
