Abstract: An electrophoretic display includes a row driver connected to an electrophoretic display panel via a plurality of gate scanlines, and the row driver has a decoder. When the electrophoretic display is to update a picture that includes only a block to be changed, the decoder decodes a start position and an end position of the block to determine a portion of gate scanlines that are occupied by the block, and the row driver drives only the portion of gate scanlines. Therefore, the update time is shorter and the power consumption is less than that for a full update case.

Abstract: For picture updating, an electrophoretic display erases the ghost image and then continuously turns on a plurality of frames, each for changing only one gray level, so as to gradually adjust each of the pixels to a respective desired gray level, which can simplify and accelerate the picture updating, and reduce the content size of a lookup table. By incorporating with adjusting the time length of the frames, the lightness adjustment of the electrophoretic display can be simplified.
