ELECTROPHORETIC DISPLAY PANEL |
摘要 |
The electrophoretic display panel (1) for displaying pictures has drive means (100) which are arranged for controlling the potential difference of each picture element (2) to be a picture potential difference having a picture value and an associated picture duration representing a picture energy for enabling the particles (6) to occupy one of the positions for displaying one of the pictures, subsequently to be an inter-picture potential difference having an inter- picture value and an associated inter-picture duration representing an inter-picture energy and subsequently to be a subsequent picture potential difference for enabling the particles (6) to occupy one of the positions for displaying a subsequent one of the pictures. For the display panel (1) to be able to subsequently display pictures of at least relatively medium quality and to have a reduced visibility of the inter- picture appearances of the picture elements (2), the drive means (100) are arranged for controlling for each picture element (2) the inter- picture value to have a sign opposite to a sign of the picture value, the inter-picture energy to be insufficient to substantially change the position of the particles (6) and chosen in a range from larger than zero to substantially equal to the picture energy for reducing an undesired charge accumulation in the picture element (2).
