초록

TFT-LCD simulator, PDAST(Pixel Design Array Simulation Tool) could simulate the effect of the variation on the pixel characteristics. Since feed-through voltage in TFT-LCD can be a serious problem to pixel voltage characteristics, it should be compensated. It is applicable to various kinds of TFT-LCDs and can be used to calculate the spontaneous part of common electrode voltage accurately. Also, PDAST can estimate pixel voltage according to various inversion methods. It allows high-speed calculation and the information obtained from this study could be utilized to design the larger area and finer image quality panel.
