Abstract
A driving method of an electrophoretic display is provided. The driving method includes the following steps. A plurality of pixels of a display panel of the electrophoretic display are configured as a plurality of blocks. A common voltage of the display panel is set to a first voltage. A plurality of scanning signals are inputted to a plurality of scanning lines of the display panel in order in which scanning lines corresponding to the same block receives the same scanning signal. A plurality of data lines of the display panel are measured to obtain at least one peak voltage corresponding to each of the blocks. A feed through voltage corresponding to each of the blocks is determined according the peak voltages corresponding to the blocks. A plurality of driving signals which drive each of the blocks are adjusted according the feed through voltage corresponding to each of the blocks.
