The LCD1, LCD2, LCD3 output paths consist of several processing blocks (see Figure 11-73):
- Overlay manager
- Gamma correction unit
- Color phase rotation (CPR) block, also used for RGB-to-YUV color space conversion (CSC)
- Active matrix dithering with TDM
- BT.656
- BT.1120
- Synchronization buffer
- Timing generator
The display subsystem supports active matrix technologie (monochrome and color modes):
- Active matrix displays: the configuration of colors depends on the color depth:
- 24 bpp supports 16,777,216 colors.
- 18 bpp supports 262,144 colors.
- 16 bpp supports 65,536 colors.
- 12 bpp supports 4096 colors.
Note: In BT.656 mode only bits 9 through 0 are used from DISPC_LCD_DATA[23:0] data bus.
