A method of displaying colour data on an electronic paper display is displayed. The method comprises providing an electronic paper display having display pixels at a display pixel pitch and providing a colour filter for said display. Said colour filter comprises groups of coloured filter elements, each said coloured filter element having one of a plurality of different colours, wherein each group of coloured filter elements defines a pattern of said coloured filter elements. In said pattern a coloured filter element overlies an integral number, n, of said display pixels, where n is two or more. The method also comprises providing colour image data defining a plurality of colour image planes, one for each of said different colours. Data in a said colour image plane comprises image pixel data defining values for image pixels corresponding to said display pixels. The method also comprises selecting, from said data in each said colour image plane, data for image pixels corresponding to display pixels over which the filter elements of the respective colour for the colour plane lie; and using said selected data to drive said electronic paper display; wherein on said display a rate of spatial variation of said selected data for said image pixels is less than said display pixel pitch. |
