摘要： Bi-stable electrophoretic display device (1) having a normal mode and a scrolling mode, in which image transitions are effected by causing the charged particles (8,9) to toggle between the intermediate optical states (e.g. grey-to-grey) or between an extreme optical state and an intermediate optical state (e.g. white-to-light grey), with a corresponding short update time tscroll. When the device (1) enters a scrolling mode in response to a scrolling command from a user, picture elements are first driven to a special scrolling optical. state, after which drive waveforms for scrolling mode are used for fast toggling between two scrolling states. An increased scrolling speed and very short scrolling time can be realized, without adversely affecting image quality during a normal mode.

摘要： A driver (15, 10, 16) for an electrophoretic display (1) comprising pixels (18), comprises a controller (15) to select a particular drive waveform (Dij) for a particular one of the pixels (18) out of a particular set of drive waveforms (Si) being selected out of a plurality of sets of waveforms (So, . . . , Si). A selection of the particular set of drive waveforms (Si) out of the plurality of sets of waveforms (So, . . . , Si) is determined dependent on optical states of adjacent pixels (18) being adjacent to the particular one of the pixels (18) such that the crosstalk between the adjacent pixels (18) and the particular one of the pixels (18) is decreased. Each set of drive waveforms (Si) comprises drive waveforms (Dij) required to obtain optical states of the particular one of the pixels (18) suitable for a particular configuration of the optical states of the adjacent pixels (18). A selection of the particular drive waveform (Dij) from the particular set of drive waveforms (Di) is determined by a desired optical state of the particular one of the pixels (18). A pixel driver (10, 16) supplies the drive waveforms to the pixels (18).

摘要： In a first display mode, only the information in a first sub-area (W1) of the display screen of a bi-stable matrix display (100) has to be updated. In a second display mode, the information in a second sub-area (W2) of the display screen has to be updated. The information in the first sub-area (W1) is displayed using optical states which require first drive voltage waveforms (DV1) having a maximum duration equal to a first image update period (IUP1). The information in the second area (W2) is displayed using optical states which require second drive voltage waveforms (DV2) having a maximum duration equal to a second image update period (IUP2). The optical states allowed to be used during the first mode are selected to obtain a first image update period (IUP1) which is shorter than the second image update period (IUP2). In this manner, the refresh rate of the information in the first area (W1) is higher than the refresh rate in the second area (W2).

摘要： The electrophoretic display panel has an electrophoretic medium having charged particles, a plurality of picture elements, electrodes associated with each picture element for receiving a potential difference, and drive means. The drive means are arranged for controlling the potential difference of each of the plurality of picture elements to be a potential difference for enabling the particles to occupy the position corresponding to image information. For the display panel to be able to provide a smoother change-over from one image to another, the drive means are arranged for providing, during a portion of the image transition period, different starting times for application of the potential differences within the duration of the portion of the transition period for potential differences having a duration less than the maximum duration of the portion of the image transition period.
