    摘要: The invention relates to a method for calibrating an electrophoretic display panel (1) comprising a plurality of pixels (2) capable of representing at least two optical states by receiving driving signals (30), comprising the steps of displaying a first calibration image (22) containing said optical states in a first arrangement on said electrophoretic display panel and providing driving signals (30) to said pixels (2) corresponding to a required image (23) resulting in a second calibration image (24) containing said optical states in a second arrangement on said electrophoretic display panel (1). The second calibration image (24) is compared with said required image (23) to determine differences (26) between said second calibration image (24) and said required image (23) and said driving signals (30) are adjusted in accordance with said differences such that said second calibration image (23) and said required image (24) match. By this method the uniformity of the electrophoretic display (1) is improved.

    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 (IUPI). 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 off the information in the first area (WI) is higher than the refresh rate in the second area (W2).

    摘要: A method and system for controlling electrophoretic and other bi-stable displays (310). Coded data (605, 610, 615) for driving the display is stored in memory (320) for different pixel transitions and different temperatures. The coded data includes voltage level and timing information for the different pixel transitions. A portion (705, 710, 715, 720, 725, 730) of the coded data is retrieved by a controller (100) such as an ASIC based on a selected pixel transition, temperature, and update mode. The portion of the coded data, which may include fixed length frame instructions, is decoded to provide decoded data. The decoded data is used to provide voltage waveforms for driving the display.

    摘要: An electrophoretic display panel and a method for driving an electrophoretic display panel in which the drive pulse, i.e. the grey scale pulse, to bring an element from a preceding optical state to an optical state is split in more than one sub-pulses. A more gradual introduction of the grey scale is thereby achieved reducing the suddenness of the transition form one image to another. Preferably application of the grey scale potential differences is preceded by application of reset pulses in which case the preceding optical state is an extreme optical state.

    摘要: A display device (1) comprises two or more groups of display elements having electrophoretic particles (8,9), a pixel electrode (5) and a counter electrode (6). Drive signals (50, (V,t)drive, (V,t)reset) are supplied to the electrodes to bring the display elements in a predetermined optical state. The drive signals are preceded by preset signals (53, (V,t)preset) to release the electrophoretic particles but too low in intensity to enable the particles to change the optical state significantly. The preset signals supplied to the groups show differences in phase. This reduces flicker. The preset and drive signals are, in operation, so supplied that the phase of the preset pulse preceding the drive pulse is, in respect of the drive pulse, substantially the same for all groups. The combination of a drive and preceding preset pulse is then for the groups substantially the same, reducing grey level variations.

    摘要: Electophoretic display units (1) are driven with a relatively low amount of power and more efficiently by addressing the pixels (11) only once during a sequence of frame periods. Compared to addressing a pixel (11) each frame period, for signals having a duration of more than one frame period, a large amount of power is saved. During a sequence of frame periods formed by a time-interval (T1-T8), one or more reset pulses (R) or one or more driving pulses (Dr) are provided. The addressing of a line of pixels (11) can be skipped during a sequence of frame periods if all pixels (11) of the line of pixels (11) have to remain unchanged. Signals having a duration of two or more frame periods do not need to be supplied to the pixels (11) each frame period, but need to be supplied only once by addressing the pixels (11) only once during a sequence of frame periods.
