  • Abstract
    The proposed pixel circuit for active-matrix organic light-emitting diode display compensates threshold-voltage-shift (ΔVth) of drive TFT by utilizing ΔVth-dependent charge transfer caused by a TFT-based Metal-Insulator-Semiconductor (MIS) capacitor. Its effectiveness is verified by simulation results.
