Abstract
The invention relates to an electronic device comprising a limited color display and a method of driving the display. The display has an array of pixels, a driver for driving each of said pixels in said array and a color filter which is aligned with said display whereby each of said pixels is sub-divided into a plurality of sub-pixels of different colors. The method 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 colors within the brightness image; and outputting said output signal to said driver to drive the display.
