摘要： Electrophoretic 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 (T 1 -T 8 ), 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.

摘要： Electrophoretic display units (1,100) are provided with switching circuits (50) to reduce the energy necessary for supplying data pulses (DP1, DP2) to pixels (11) via a data electrode (31,32,33,34). This energy is proportional to a differential voltage to be realised and to a capacitance (13) to be charged or discharged, which is formed by a combination of a capacitance of the pixel (11) and a capacitance of the active matrix. Due to this capacitance of the active matrix being much larger, a relatively large amount of energy is necessary. The switching circuit (50) couples the data electrode (31,32,33,34) to a voltage reference source (REF) like ground between two selection pulses (SP1, SP2) to be supplied sequentially to two respective pixels (11) coupled to the same data electrode (31,32,33,34). This reduces the amount of discharging to be realized by the data drivers (3). As a result, the maximum energy necessary is reduced. To reduce the power consumption of the entire electrophoretic display unit (1,100), this should be done preferably for data pulses (DPI, DP2) having amplitudes with opposite polarity only.

摘要： 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.

摘要： The electrophoretic display unit (1) comprises drivers (60,61) for driving pixels (11) groups (70,71) of lines in parallel during data-independent parts of frame periods. During data-independent parts of frame periods, the groups (70,71) of lines are driven with common data and during data-dependent frame periods, the groups (70,71) of lines are driven with specific data. Preferably, the drivers (60,61) are row drivers, with the groups (70,71) of lines being groups of rows. During data-independent parts of frame periods, especially when shaking pulses are applied, the frame period can be reduced.

摘要： An image is updated on a bi-stable display (310) such as an electrophoretic display in a transition from a current image state to a subsequent image state. A voltage waveform (600, 620, 640, 660; 700, 720, 740, 760) is selected based on the current and subsequent image states, and a previous image state. The bi-stable display (310) is driven from the current image state to the subsequent image state using the selected voltage waveform. For a given transition from the current to the next image state, different waveforms are stored for different previous states, e.g., black, dark grey, light grey and white. The different waveforms may have different drive pulse (DR) or reset pulse (RE1, RE2) energies. In a trial and error optimization process, different waveforms with different reset and/or drive pulse energies are tested for different previous image states to see which waveform yields the smallest greyscale error.
