<p>A passive matrix electrophoretic display (1) in which a select driver applies a select waveform to each line of the matrix and a data driver applies a sequence of drive signals (D) to the columns of the matrix according to the image to be displayed on the device . The select waveform includes a reset signal (R15Rn) which precedes a select signal (S) to be applied to the picture elements of a line of the matrix. The reset signals (Rl) may be applied substantially simultaneously to at least a subset of lines of matrix, before respective drive signals (D) are applied to the pixels (2) thereof . Alternatively a select waveform (including the reset signal (RN) ) may be applied to each line of the matrix sequentially, with the drive signals (D) being applied to the pixels (2) of each selected line of the matrix whilst the next line is being reset. As a result, the image update time of the device (1) is reduced.</p> |
