Liquid Crystal Display Controller (LCDC)
• 16 simultaneous gray-scale levels from a palette of 16 for monochrome display
• Support for:
— Maximum resolution of 800 × 600
— Passive color panel:
– 4 (mapped to RGB444) / 8 (mapped to RGB444) / 12 (RGB444) bits per pixel (bpp)
— TFT panel:
– 4 (mapped to RGB666) / 8 (mapped to RGB666) / 12 (RGB444) / 16 (RGB565) / 18
(RGB666) bpp
— 16 and 256 colors out of a palette of 4096 colors for 4 bpp and 8 bpp CSTN display respectively
— 16 and 256 colors out of a palette of 256K colors for 4 bpp and 8 bpp TFT display respectively
— True 4096 colors for a 12 bpp display
— True 64K colors for 16 bpp
— True 256K colors for 18 bpp
— Additional support details are shown in

• Standard panel interface for common LCD drivers
• Panel interface of 1-, 2-, 4-, 8-bit for monochrome panels
• Panel interface of 12-, 16-, 18-bit for color panels
• For 4 bpp and 8 bpp a palette table is used for re-mapping of data from memory, independent of
type of panel used. For the 1 bpp, 2 bpp, 12 bpp, 16 bpp, and 18 bpp the palette table is by-passed.
• Interface to passive and active color panel (TFT)
Supports timing requirements for Sharp 240 × 320 HR-TFT panel
•
• Hardware-generated cursor with blink, color, and size programmability
• Logical operation between color hardware cursor and background
• Hardware panning (soft horizontal scrolling)
• 8-bit pulse-width modulator for software contrast control
• Graphic window support for viewfinder function in color display
