Circuitry comprises 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 display image transition from a current display image to a second, 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 electrical charge, in the second display image; switching circuitry, responsive to the detector circuitry, to divert electrical charge from the set of display elements to secondary charge store in response to initiation of the display image transition.
