Abstract
A method and apparatus includes row-major memory mapping for a graphics memory (14) while providing data to a column-major display such as a pixel array (19). The transfer of data is provided from a row-major memory map to data formatted for refreshing a column-major display. The column-major pixel array (19) provides a display with energy saving benefits for illuminating the LEDs. A software developer can provide graphics data generated or transferred by a microcontroller (12) for storage in the row-major graphics memory (14). The embodiment supports the display features such as the grey-scale mode and bi-level mode.
