The invention relates to an electronic device comprising a limited colour display, such as a grey scale or a 16 colour e-reader type display, and a method of driving the display using image data intended to be displayed by a full colour display. The display has an array of pixels, a driver for driving each of said pixels in said array and a colour filter which is aligned with said display whereby each of said pixels is sub-divided into a plurality of sub-pixels of different colours. The method involves processing the full colour image data and comprises; receiving a target image; generating a brightness image for said target image by determining a brightness value for each sub-pixel within said display; generating an output signal from said brightness image by determining an output value for each of said plurality of sub-pixels of different colours within the brightness image; and outputting said output signal to said driver to drive the display. |
