ELECTROPHORETIC DISPLAY PANEL

摘要

The electrophoretic display panel (1), for displaying a picture, has drive means (100) which are arranged for controlling the potential difference of each picture element (2) to be a sequence of preset potential differences and subsequently to be a picture potential difference for enabling the particles (6) to occupy one of said positions for displaying the picture. Each preset potential difference represents a preset energy and has as a result a change of the position of the particles (6). For the display panel (1) to be able to display a picture of relatively high quality and to have relatively small changes in the appearances of picture elements (2) as a result of the sequences of preset potential differences even when the number of preset potential differences in the sequences is relatively small, the drive mean (100) are further arranged for controlling for each picture element (2) of at least a number of the picture elements (2) the preset energies of the preset potential differences in the sequence to depend on a serial number in the sequence to obtain for each preset potential difference in the sequence a substantially equal magnitude of the change of the position of the particles (6).
