ABSTRACT:
A liquid crystal display has a plurality of buffers46controlling a plurality of column lines. The buffers have a bias current control input47which is controlled, in the example by timing circuitry50, to current during the row period for writing to each row of pixels. In particular, the row period may be divided between a drive period with a high buffer bias current and a voltage maintenance period with a lower buffer bias current.
