| 摘要 |
The invention relates to an electrophoretic display device ( 1 ) comprising charged particles ( 8, 9 ) in a fluid ( 10 ) between a pair of electrodes ( 5, 6 ). A drive means is arranged and configured to supply a drive waveform to the electrodes ( 5, 6 ), the drive waveform comprising a sequence of drive signals for effecting respective optical transitions by causing the charged particles ( 8, 9 ) to occupy a predetermined position between the electrodes ( 5, 6 ) according to image data required to be displayed, and at least one voltage pulse, preferably prior to each drive signal, for inducing a substantially uniform electric field distribution across the display device ( 1 ). This has the effect of significantly reducing edge image retention and/or ghosting.
