Abstract

The invention provides a display driver integrated circuit, for connection to a small-area display, the integrated circuit including a hardware-implemented graphics engine for receiving vector graphics commands and rendering image data for display pixels in dependence upon the received commands, and also including display driver circuitry for driving the connected display in accordance with the image data rendered by the graphics engine. In another aspect the graphics engine is held within the display module, but not embedded in the display driver IC. The invention provides graphics acceleration that increases display performance, but does not significantly increase cost of manufacture. Power consumption in comparison to non-accelerated CPU graphics processing is lowered.
