2.7.2.1 18-bit Color Mapping
The color mapping for the 18-bit LVDS interface is standardized and is shown in the following
picture:

2.7.2.2 24-bit JEIDA Color Mapping
The JEIDA color mapping is compatible with the 18-bit LVDS interface. Therefore, the mapping is
sometimes also called “24-bit / 18-bit Compatible Color Mapping”. The signal names of the color
bits are renamed (e.g. the 18-bit R5 is renamed to 24-bit R7) but the position of the MSB is kept as
the same. The additional least significant bits R0, R1, G0, G1, B0, and B1 are transmitted in the
additional fourth LVDS data pair.

2.7.2.3 24-bit VESA Color Mapping
Most of the 24-bit LVDS displays follow the VESA Color mapping. The VESA color mapping does
not rename the signal bits. This means that the position of the MSB is different as they are
available in the additional data pair. Hence, the VESA color mapping is not compatible with the
18-bit interface.
