The dynamic characteristics of the capacitance of liquid-crystal display (LCD) pixel constituting the active matrix LCD device using amorphous thin film transistors (TFTs) have been analyzed; an electrically equivalent circuit model is proposed based on the obtained results. The model consists of nonlinear resistors and dynamic elements such as capacitors or inductors and can represent the voltage and time dependence of the capacitance value in the LCD pixel. The proposed model is incorporated into the circuit simulator SPICE as a built-in model. [ABSTRACT FROM AUTHOR]
