Number of colors
The number of colors supported differs per panel type.
TFT panels
TFT panels support one or more of these color modes:
1 bpp, palettized, 2 colors selected from available colors
2 bpp, palettized, 4 colors selected from available colors
4 bpp, palettized, 16 colors selected from available colors
8 bpp, palettized, 256 colors selected from available colors
16 bpp, direct 5:5:5 RGB, with one bpp usually not used. This pixel is still
output, and can be used as a bright bit to connect to the least significant
bit (lsb) of R, G, and B components of a 6:6:6 TFT panel.
24 bpp, direct 8:8:8 RGB, providing over 16 million colors
Each 16-bit palette entry is made up of five bpp (RGB) plus a common intensity bit,
which provides better memory use and performance compared with a full six bpp
structure. The total amount of colors supported can be doubled from 32K to 64K if
the intensity bit is used and applied to all three color components simultaneously.
Color STN panels
Color STN panels support one or more of these color modes:
1 bpp, palettized, 2 colors selected from 3375
2 bpp, palettized, 4 colors selected from 3375
4 bpp, palettized, 16 colors selected from 3375
8 bpp, palettized, 256 colors selected from 3375
16 bpp, direct 4:4:4 RGB, with 4 bpp not used
