LUT Control
The items in this section control the color depth for the SED1374 after initialization.
Figure 7: LUT Control
The color depth selections in this section will become enabled or disabled in response to
the panel dimensions entered. (i.e. there is only enough memory to operate a 640x480 panel
at 1 bit per pixel so the selections for 2 BPP, 4 BPP and 8 BPP would be disabled if this size
pane was selected)
• 1 BPP – sets the color depth to 1 bit per pixel.
• 2 BPP – sets the color depth to 2 bit per pixel.
• 4 BPP – sets the color depth to 4 bit per pixel.
• 8 BPP – sets the color depth to 8 bit per pixel.
