9.2: A New Driving Method to Compensate for Row Line Signal Propagation Delays in an AMLCD and Analysis Using a Distributed Electrical Model

The distributed capacitive and resistive make up of both the row and column lines in an AMLCD introduces significant propagation delays to their respective addressing signals. The row signal delay is conventionally accommodated by shortening the row select time, which must be offset by lower TFT on-resistance to provide adequate charging ratios of the pixels. We present an alternative in which the column driver signals are progressively delayed to match the row signal propagation. The benefit is of particular interest to large-area, high-resolution, wide-aspect-ratio, LCD TVs.
