Methods and apparatus for utilizing pixel sub-components which form a pixel element of an LCD display. R, G and B luminous intensity values generated as part of a weighted scan conversion (element 812) are packed into 8 bit values (element 804). In accordance with another feature, a look-up table (element 831) is used to convert between glyphs represented using a set of packed pixel values (element 807) into R, G, and B pixel values by a display (element 547). The processed pixel values represent the result of performing unpacking, gamma correction, color filtering and color palette selection operations (element 833) using the packed pixel values (element 807). One look-up table (elements 832, 832', 832") is stored for each different combination of color palette selection, gamma correction and pixel format conversion. Switching between a light foreground/dark background is achieved in accordance with the present invention. |
