NS9750B-A1 Datasheet 03/2006
This LCD TFT panel signal multiplexing table shows the RGB alignment to a 15-bit TFT with the
intensity bit not used. The intensity bit, if used, should be connected to the LSB (that is,
RED[0],
GREEN[0], BLUE[0]
) input of an 18-bit LCD TFT panel as shown in the next table.
If you want reduced resolution, the least significant color bits can be dropped, starting with
Red[0], Green[0], and Blue[0].
