Abstract
A liquid crystal display has a plurality of bufferscontrolling a plurality of column lines. The buffers have a bias current control inputwhich is controlled, in the example by timing circuitry, 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.
