ABSTRACT:
A display apparatus including a matrix display device with pixels wherein particles move in a fluid between electrodes. An optical state of the pixels is defined by a value of a drive voltage and a duration of a drive period during which the drive voltage is present across the pixel. A DC-balancing circuit controls the amplitudes of the drive voltages and/or durations of drive periods to obtain a substantially zero time-average value across each pixel or across each sub-group of pixels. This control of the amplitude of the drive voltages and/or the duration of the drive periods allows minimizing the image retention, without requiring reset pulses causing all pixels to become temporarily white or black.
