Abstract: A data driver for an electrophoretic display (EPD) includes multiple driver sub-circuits. Each of the driver sub-circuits includes first and second latches, first and second capacitors, a multiplexer and a comparator. The first and second latches respectively provide updated latch image data and current latch image data in response to original image data. When the updated and current latch image data correspond to different levels, the comparator controls the multiplexer in a first period to selectively couple one of the first and second capacitors to a driver end, so as to recycle charges at pixels, and controls the multiplexer in a second period to selectively couple the other of the first and second capacitors to the driver end to pre-charge the pixels with the charges.
