Color Modes

In color mode, the S1D13504 supports three, 16 position, 4 bit wide color LUTs (red, green, and blue). Depending on the selected pixel size, these LUTs will provide from 1 to 4 banks.

1 bpp Color

In 1 bpp color mode, the LUT is limited to a single 2 entry bank per color. The LUT bank select bits have no effect in this mode.

The following table shows the recommended values for obtaining a Black-and-White mode while on a color panel.

2 bpp Color

In 2 bpp color mode, the 16 LUT entries are divided into four separate 4 entry banks per color.

The following table demonstrates recommended LUT data values which produce Bank 0 = low intensity, Bank 1 = high intensity, Bank 2 = inverted low intensity, Bank 3 = inverted high intensity.
