A IMAGE-SIMULATION METHOD FOR ELECTRICAL CHARACTERISTIC ANALYSIS OF TFT-LCD

摘要

An image simulation method for analyzing the electrical characteristic of a TFT-LCD panel is provided to optimize parameters such as the drain, gate, and source of a transistor and the length, width, and thickness of gate and data lines and perform computer simulation for the frame, dot, column inversion driving of an LCD driving method to consider the electrical characteristic of the TFT-LCD panel in transmitting a video signal, thereby solving a problem caused by RC-delay in transmitting the video signal. In an image simulation algorithm, pixels of a 3D(Three-Dimensional) structure are embodied using TechWiz LCD, 3D liquid crystal simulator(S101). Resistance and capacitance is extracted to make a unit-pixel equation circuit(S102). Simulation is performed for the electrical characteristic of a TFT(Thin Film Transistor)-LCD panel to extract a gamma curve and a voltage-transmittance curve(S106,S107).
