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.

摘要： An electrophoretic display panel (1), comprising a plurality of picture elements (2), an electrophoretic medium (5) having charged particles (6), and first and second electrodes (3,4) associated with each picture element (2) for receiving a potential difference. As the display (1) is addressed, for each picture element (2), the product of voltage and duration of picture voltages is read from a controller (102). After one or more image update periods, there will be a history generated of the total energy seen by each picture element (2). DC balancing is achieved by introducing feedback loop into the controller (102) which attempts to reduce the number stored in the memory (104) to zero, for each picture element (2) by applying one or more high voltage short pulses with a polarity opposite to the number stored in the memory (104).

摘要： The electrophoretic display panel (1) for displaying a picture has a plurality of pixels (2) and drive means (100). Each pixel (2) has two electrodes (3, 4) for receiving a potential difference and charged particles (6) capable of occupying a number of different positions between the electrodes (3, 4). The drive means (100) are able to supply a sequence of potential difference pulses to each pixel (2), each sequence having, to display the picture, a picture pulse for bringing the particles (6) into one of the positions. For the display panel (1) to be able to display a picture of at least relatively medium quality even shortly after the application of the sequences, with respect to at least a number of the pixels (2) having received picture pulses for bringing their particles (6) into extreme positions, the sequence of each pixel (2) out of said number has an additional picture pulse subsequent to the picture pulse, which additional picture pulse serves to prevent the particles (6) from substantially changing their position.

摘要： In a method of driving an electrophoretic display, during an image update period (IUi) wherein the pixels (18) of the display are addressed to refresh an image displayed, a drive waveform (DWi) is supplied (10,16) to an associated one of the pixels (18). The drive waveform (DWi) comprises successively a first pulse (Ri, Si) with a first voltage level (+VM, -VM) and a drive pulse (Di) with second voltage level (VDi). The drive pulse (Di) has a variable voltage level to allow obtaining a desired intermediate optical state of the pixel (18) with a high accuracy. An absolute value of the second voltage level (VDi) of the drive pulse (Di) is smaller than an absolute value of the first voltage level (+VM, -VM) of the first pulse (Ri, Si), to minimize the total image update time.
