A compact model for circuit simulation of TFT-LCD panel
In this paper, we report a novel compact SPICE model for circuit simulation of LCD-TVs. In this work, we generated a SPICE model for a unit cell of TFT-LCD by taking all of parasitic capacitances and resistances into account. In order to extract circuit model from a unit cell, an electrical connectivity of resistors and capacitors was generated through the pattern analysis data including electrode and port data, followed by the calculation of the parasitics using a finite element method (FEM). Moreover, we employed a piecewise linear voltage-controlled capacitor model with calculated values in order to take voltage dependency of LC capacitance into account. Consequently, we generated a new kickback model which considers the influence of adjacent bus lines.
