Abstract
Displaying image data with sub-pixel precision on display devices having pixels with separately controllable pixel sub-components, such as those used in liquid crystal display devices. Samples of the image data are obtained, and spatially different sets of one or more of the samples are mapped to individual pixel sub-components as opposed to mapping sets of samples to entire pixels. Luminous intensity values based on the mapped sets of samples are generated and used to control the operation of the separately controllable pixel sub-components. The image is thereby displayed on the display device, with different portions of the image being represented by different pixel sub-components, resulting an image with sub-pixel resolution. The image data can represent a text character, in which case the stem width of a stem of the text character can have a value that is not an integer multiple of the width of a full pixel.
