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.

摘要： The electrophoretic display panel (1) for displaying a picture and a subsequent picture has drive means (100) which are able to control for each pixel (2) the potential difference to have a picture value to provide the pixels (2) with a respective picture appearance being either extreme or intermediate, subsequently to have an inter-picture value to provide the pixels (2) with a respective inter-picture appearance, and subsequently to have a subsequent picture value. For the display panel (1) to be able to provide the pixels (2) with the inter-picture appearances which are in general relatively little visible, the drive means (100) are able to control for each pixel (2) an estimate potential difference as the inter-picture value to provide the pixels (2) with a respective estimate picture appearance as the inter-picture appearance.

摘要： A touch sensitive matrix display senses touch input in sense periods (SP) which are selected to occur non-concurrently with data (DA) written to the pixels (10) of the matrix display during the addressing period (AP). As now, no data (DA) is written to the display while the sensing is performed during the sense periods (SP), the sensing will be less complicated. The sense periods (SP) are selected to occur in-between successive addressing periods (AP) because the display has pixels (10) of which the optical state is maintained substantially longer than the addressing period (AP) lasts. Such a hold period (HP) which lasts substantially longer than the addressing period (AP) is for example available in bistable displays such as electrophoretic displays.
