Claim 17:
18. A method comprising:
controlling display of a prevailing display image by display elements of a display device, by generating a signal providing electrical charge for storage by display elements, in which an electrical charge stored by a display element controls a display output of that display element;
detecting, for a given display image transition from a current display image to a second, different, display image, a first set of one or more display elements which are in a respective first state controlled by a first stored electrical charge in the current display image and which are required to be in a respective second state controlled by a second stored electrical charge, lower than the first stored electrical charge, in the second display image;
diverting, in response to the detection, electrical charge from display elements of the set of one or more display elements to a secondary charge store in response to initiation of the display image transition; and
detecting, for the given display image transition, a second set of one or more display elements which are in a respective second state controlled by a second stored electrical charge in the current display image and which are required to be in a respective first state controlled by a first stored electrical charge, greater than the second stored electrical charge, in the second display image,
wherein the secondary charge store comprises one or more of the second set of one or more display elements.
