4.2 Look-Up Table Organization

4.2.1 Color Modes

1 bpp color

When the S1D13705 is configured for 1 bpp color mode, the LUT is limited to selecting colors from the first two entries. The two LUT entries can be any two RGB values but are typically set to black-and-white.

Each byte in the display buffer contains eight adjacent pixels. If a bit has a value of “0” then the color in LUT 0 index is displayed. A bit value of “1” results in the color in LUT 1 index being displayed.

The following table shows the recommended values for obtaining a black-and-white mode while in 1 bpp on a color panel.
