Abstract (en)

[origin: WO9953472A1] A display control device (30) for a light-emissive display (2), comprising: input means (32, 33) for receiving display data defining a visual display pattern; processing means (33, 34, 35) for processing the display data to generate control data for controlling the pixels of the display and having a first, normal mode of operation in which it controls the pixels to display the pattern as defined by the display data, and a second, power-saving mode of operation in which it controls a set of pixels of the display to operate with reduced power consumption whilst maintaining display of the pattern; and output means for connection to the pixels to transmit the control data to the pixels.
