A Study on Optimizing Parameter for Driving Waveform of TFT-LCD Panel

TFT-LCD 패널의 구동 파형을 위한 파라미터 최적화 설계에 관한 연구

The purpose of this paper was to find out the stabilized and effective value of RC-parameter by using PSpice simulation, considering that gate signal voltage can be distorted by RC-delay of signal line. the results of this study were as follows: TFT-LCD with high quality resolution increased the number of gate signal line and this made TFT on-time shorter over-width of signal line to improve the performance of TFT made the electrostatic capacity increase and the time constant higher, making problems and errors. and owing to the decrease of the aperture ratio, an electro optic character of LCD, we must consider the capacity and the condition of production process in deciding the width and the thickness of the gate signal line.
