General Description

The Graphic LCD Controller (GraphicLCDCtrl) component provides the interface to an LCD panel that has an LCD driver, but not an LCD controller. This type of panel does not include a frame buffer. The frame buffer must be provided externally.

This component also interfaces to an externally provided frame buffer implemented using a 16-bit wide async SRAM device.
