In this paper, we propose a novel simulation scheme, which we call "block image simulation," for the image analysis of a full thin film transistor liquid crystal display (TFT-LCD) panel. The proposed approach makes it possible to estimate viewable image for varying conditions as well as electrical characteristics of a TFT-LCD panel covering all the pixels. We also propose a compact circuit model for a TFT-LCD pixel, which accounts for the parasitic capacitors present between the neighboring gate and data lines and voltage-dependent liquid crystal (LC) pixel capacitance. In this work, we also report our successful simulation study on an exemplary 10.4 inch SVGA (800 x 600) LCD panel in terms of crosstalk, flickers, shading, and gray scale error.
