Abstract
A method of driving an active matrix liquid crystal display in a partial display mode is provided, together with a display operable in accordance therewith. A live portion ( ) of the display is driven to display image data ( ) and a dormant portion ( ) is driven to display a substantially constant grey scale level output. The method comprises applying a signal ( ) to each of the column address conductors ( ) associated with the dormant portion ( ) which comprises a combination of a signal substantially the same as the signal ( ) applied to the counter electrode and kickback correction, such that the resultant kickback correction applied to each of the picture elements associated with the dormant portion ( ) substantially corresponds to the grey scale level of the dormant portion. This serves to reduce the power consumption of the dormant portion ( ), whilst avoiding the application of a substantial DC across the picture elements of the dormant portion ( ).
