DISPLAY DEVICES AND DRIVING METHOD THEREFOR

摘要

Driving schemes are described in which rows (1 to m) are selected one at a time and column data voltages are inverted to provide inversion schemes for active matrix liquid crystal display devices comprising pixels (12) arranged in rows (1 to m) and columns (1 to n). The polarity of column data signals is only inverted every set of row. An odd number of sets of column voltages are applied within the frame. This reduces power consumption, and also drives the array of pixels during the frame blanking interval so as to reduce undesirable display artefacts.
