    • The electrophoretic display panel (1), for displaying a picture, has drive means (100) which are arranged for controlling the potential difference of each picture element (2) to be a sequence of preset potential differences and subsequently to be a picture potential difference for enabling the particles (6) to occupy one of said positions for displaying the picture.

    • Electrophoretic display units (1) are driven more flexibly by creating sequences of frame periods in which at least two frame periods of the sequence of frame periods have a different frame period duration and by selecting frame periods from a sequence of frame periods for providing driving pulses to the pixels (11). The number of possible gray values is increased, and the gray values can be generated more accurately. During the rest of the frame periods not chosen for driving the pixel (11), this pixel (11) keeps its gray value due to the bi-stable character. A frame period duration of a frame period is adapted by delaying a start of a next frame period. By supplying data-dependent signals having sections with a positive amplitude and with a negative amplitude, the net driving result is the difference between the sections with the positive and negative amplitudes, to further increase the number of possible gray values.
    • 电泳显示单元(1)通过创建帧周期的序列而被更灵活地驱动,其中帧周期序列的至少两个帧周期具有不同的帧周期持续时间,并且通过从用于提供驱动脉冲的帧周期序列中选择帧周期 到像素(11)。 可能的灰度值的数量增加,可以更准确地生成灰度值。 在未被选择用于驱动像素(11)的帧周期的其余部分期间,该像素(11)由于双稳态特性而保持其灰度值。 通过延迟下一帧周期的开始来适配帧周期的帧周期持续时间。 通过提供具有正幅度和负幅度的部分的数据相关信号,净驱动结果是具有正和负幅度的部分之间的差异,以进一步增加可能的灰度值的数量。

    • A matrix display device comprises an array of addressable pixels (10) each having a display element (20) and a control circuit for controlling the operation of the display element. The control circuit includes a charge storage capacitor (36) and a photosensitive device (40) coupled to the storage capacitor for regulating charge stored on the storage capacitor (36) in accordance with light falling on the photosensitive device (40). The control circuit further comprises means for independent voltage control (42) of a gate terminal of the photosensitive device (40), preferably a phototransistor. In this way a more efficient and flexible biasing of the phototransistor is possible. The means preferably comprise a second row line (42) being connected to the gate terminal of the photosensitive device (40). This additional line allows also the use of transistors of the same polarity for this type of pixel circuit, saving additional process masks (and costs). In addition, it becomes possible to use the phototransistor as a TFT switch. This dual function (phototransistor/TFT switch) enables the pixel circuit to provide additional features; for example duty-cycle techniques for motion blur compensation.
