Electrophoretic display with reduced look-up-table memeory

摘要

An display device ( 301 ) has reduced memory ( 314 ) requirements for temperature compensation data. A scaling factors ( 433 ) for various temperatures and a look-up table for a waveform which is optimized to drive the grayscale for a given display temperature are stored in memory ( 314 ). The waveform for a particular temperature of the display ( 301 ) is derived from the look-up table and scaling factors ( 433 ). At some temperatures, only certain parts of the waveform need be varied, and only these parts require accurate scaling from the look-up table.
