The distributed capacitive and resistive nature 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 requires lower TFT on‐resistance to provide adequate charging ratios of the pixels. We present a new approach to column driving which results in a much‐improved pixel‐charging ratio. The benefit is of particular interest to large‐area, high‐resolution, wide‐aspect‐ratio, LCD TVs.
