Abstract:
1. An electrophoretic display apparatus comprising: a signal controller that is configured to sequentially output a plurality of data signals in response to a plurality of image signals, select one of a plurality of preset time intervals, count the selected preset time interval from a time point to output the data signals, and sequentially output plurality of update signals used to compensate for the data signals after the selected preset time interval has lapsed based on a count result; a data driver that sequentially outputs a plurality of data voltages in response to the plurality of data signals and sequentially outputs a plurality of update voltages in response to the update signals after the preset time interval has lapsed; and an electrophoretic display apparatus panel that comprises a pixel comprising a pixel electrode, a common electrode facing the pixel electrode, and electrophoretic particles interposed between the pixel electrode and the common electrode, wherein the electrophoretic display apparatus is configured to receive the output data voltages and to apply one or more of the data voltages to the pixel electrode so as to direct the electrophoretic particles to a target position based on the data voltage applied to the pixel electrode, and is configured to maintain display of an image by maintaining the electrophoretic particles in the target position in response to the update voltage applied to the pixel electrode after the preset time interval has lapsed.
