In this work, an 8T2C pixel circuit is proposed for active matrix organic light-emitting diode (AMOLED) displays. The proposed circuit can compensate for VDD current-resistance drops, threshold voltage variations and leakage current of thin-film transistors. Simulation results demonstrate that the proposed circuit can achieve uniform display images for wearable devices.
