1. Circuitry comprising:
driver circuitry to control display of a prevailing display image by display elements of a display device, the driver circuitry 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;
detector circuitry to detect, 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; and
switching circuitry, responsive to the detector circuitry, to divert 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,
wherein:
the detector circuitry is configured to detect, 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; and
the secondary charge store comprises one or more of the second set of one or more display elements.
