Influence of the Parasitic Capacitances on the Pixel signal of AMLCDs

초록

In this paper, we report a novel method for extracting SPICE model for a unit cell of AMLCD. We investigated the influence of the parasitic capacitance on a pixel voltage drop of AMLCD. In this work, we generated a SPICE model for a unit cell of TFT-LCD by taking all of parasitic capacitances into account. In order to calculate the capacitance, we employed a finite element method. We calculated 21 capacitances including LC capacitance as a function of the applied voltage. In order to generate a SPICE model for LC capacitance, we used a piecewise linear voltage-controlled capacitor model with calculated values.
