摘要： A driver for an electrophoretic display with display cells (10) comprises first particles (1) and second particles (2) which have different optical properties and which are oppositely charged. A first reset electrode (REl) and a second reset electrode (RE2) are associated with a reservoir volume (RV). A first data electrode (DEl) and a second data electrode (DE2) are associated with a display volume (DV). A reset driver (3) supplies a reset voltage (VR) between the first reset electrode (REl) and the second reset electrode (RE2). A display driver (4) supplies a drive voltage (VD) between the first data electrode (DE1) and the second data electrode (DE2). A controller (5) controls the reset driver (3) and the display driver (4) to obtain the following sequence of states of the display cells (10): (i) a reset state wherein the first particles (1) and the second particles (2) are present in the reservoir volume (RV), (ii) a first fill state wherein the reset voltage (VR) has a first reset polarity to attract the first particles (1) to the first reset electrode (RE I) and the second particles (2) to the second reset electrode (RE2), and wherein the drive voltage (VD) has a first drive polarity and a level to attract the first particles (1) towards part of the display volume (DV) adjacent to the first data electrode (DEI), and to prevent the second particles (2) to move between the reservoir volume (RV) and the display volume (DV), (iii) a reversal state wherein the reset voltage (VR) has a second reset polarity opposite to the first reset polarity to attract the second particles (2) to the first reset electrode (REI) and the first particles (1) to the second reset electrode (RE2), and wherein the drive voltage (DV) has a second drive polarity opposite to the first drive polarity and a level for preventing movement of the first particles (1) and the second particles (2) between the reset volume (RV) and the display volume (DV), and (iv) a second fill state wherein the reset voltage (VR) has the second reset polarity, and wherein the drive voltage (VB) has the second drive polarity and a level to attract the second particles (2) towards the display volume (DV) adjacent to the first data electrode (DE I), and to prevent the first particles (1) to move between the reservoir volume (RV) and the display volume (DV).

摘要： A matrix display device (32) comprising at least one structured layer, arranged on a substrate and formed so as to include a code (31), detectable by a pointing device (33) to determine a position on the display (32). Providing the pixel structure with a location code can be achieved by relatively simple modifications of the manufacturing process. Therefore, the code can be incorporated in the display device in a very cost efficient manner, typically not increasing the manufacturing cost of a conventional matrix display. It will therefore either reduce the cost price of devices where a touch screen is already present or greatly improve the functionality of many products where a touch screen is at present too expensive.

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.

摘要： The present invention provides a novel design for color electrophoretic displays. In the display, each pixel (200) comprises at least two sub-pixels (210, 220, 230), and each sub pixel is fitted with a color filter (211, 221, 231) and contains an electrophoretic media comprising two particle types (201, 202, 203). The color filters (211, 221, 231) in the sub-pixels of each pixel have essentially non-overlapping absorption bands, and together cover essentially all of the wavelengths over which the display is operative. Furthermore, the absorption bands of the particles in each sub-pixel (210, 220, 230) each cover a portion of the wavelengths that is not covered by the filter (211, 221, 231) in the respective sub-pixel. The wavelength bands typically correspond to different colors. Thereby each wavelength band, or color, can be emitted by more than one sub-pixel in each pixel, resulting in increased brightness. According to one particular embodiment, each pixel comprises three sub-pixels having a cyan, magenta, and yellow absorbing filter, respectively.

摘要： A drive circuit for a bi-stable display comprises: a driver (101, 102) which supplies drive waveforms (DWk) to the pixels (Pij) of the display during an image update period (lUk) wherein the image presented by the pixels (Pij) is updated. A temperature sensing circuit senses the temperature of the display. A controller (103) controls the driver (101, 102) to supply, during the image update period (lUk) wherein a particular optical transition of a particular one of the pixels (Pij) is required, an associated one of the drive waveforms (DWk) to the particular one of the pixels (Pij). The associated one of the drive waveforms (DWk) comprises a sequence of a particular number of pulses (SPk), wherein consecutive ones of the pulses (SPk) of the sequence are separated by a non-zero separation period of time (SPT), during which period a voltage level is supplied which substantially keeps an optical state of the particular one of the pixels (Pij) unaltered. The particular number of said pulses (SPk), and/or a duration of said pulses (SPk), and/or a duration of the separation period (SPT) of the associated one of the drive waveforms (DWk) is determined to obtain the particular optical transition at the temperature sensed.

摘要： An electrophoretic display panel and a method for driving an electrophoretic display panel in which to bring an element from a preceding optical state to a grey scale in accordance with the image information Preset pulses and driving (grey scale pulses) are integrated into an integrated series of asymmetric (in respect of V=0) pulses. A more gradual introduction of grey scale is thereby achievable, reducing the suddenness of the transition from one image to another.
