LCDC Overview
As its name implies, the LCD controller is used to interface OMAP-L1x8/C674m/AM18xx devices to LCD panels or similar devices. The LCD controller actually consists of two independent controllers: a raster controller and a LIDD controller. Only one controller can be active at a time.
Raster Mode RGB interface with clock and synchronization signals. Typically used for graphics / color picture display. Pixel size 1/4/8 bits per color with palette 12 or 16 (RGB565) bits per color without palette Two sub-modes: active (TFT) and passive (STN). LIDD Mode MPU interface (parallel or serial) to Motorola 6800/8080 family and Hitachi 44780 family. Typically used for text display. Asynchronous interface with programmable timings.Note: Data in this wiki article deals only with Raster Mode.
More information on the LCD controller can be obtained from the TMS320C674x/OMAP-L1x Processor Liquid Crystal Display Controller (LCDC) User's Guide (SPRUFM0).
