ABSTRACT:
Image data and/or On-Screen Display (OSD) data is generated for display on a display having rows of pixels by repeatedly combining a portion of the OSD data and a portion of the display data in a display driver chip without storing more than the portion of the display data and/or the portion of the OSD data in the display driver chip at any time. The driver chip memory thereby may be reduced.
