Abstract
Methods and apparatus are described for sampling image data that includes foreground/background color information and mapping the samples to pixel sub-components which form a pixel element of an LCD display so that each pixel sub-component has a different portion of the image mapped thereto. The methods can be used with conventional color LCD displays that include pixels consisting of three non-overlapping red, green and blue rectangular pixel sub-elements or sub-components. The separately-controllable nature of individual RGB pixel sub-components is used to effectively increase a screen's resolution in the dimension perpendicular to the dimension in which the screen is striped. A scan conversion process maps samples of the image data to individual pixel sub-components, resulting in each of the pixel sub-components representing a different portion of the image. The color values are independently generated for each of the red, green, and blue pixel sub-components based on different portions of the image, rather than the color values for the entire pixel being generated based on a single sample or the same portion of the image.
