    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: 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 chive 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.

    摘要: A bi-stable display (100) is driven by supplying (101) voltage waveforms to pixels (18) of the display (100). It is determined (150), based on information to be displayed (DI) on the display (100) during an image update period (IUP), which pixels (18) have to change their optical state during the image update period (IUP). A sub-area of pixels (WI) is determined (151) which has to be updated during this image update period (IUP). The dimensions of the sub-area (W1) are dynamically determined to cover the pixels (18) which have to change their optical state during this image update period (IUP). The drive circuit (101) is controlled (152) to only address the pixels (18) of the sub-area (WI).

    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).
