Abstract
A driver arrangement for a display includes at least one driver, such as a column driver, and a delay line arrangement coupled to the driver. The delay line arrangement delays a data signal provided to the driver by a delay period selectable from a plurality of possible delay periods. The delay line arrangement includes a calibration module that, when requested, is configured and arranged to adjust a current delay period produced by the delay line arrangement towards a predetermined delay period. Displays can include the driver arrangement to provide self-calibration of the delay line.
