Description
Module Interface Type Select
Set the LCD panel type and data bus width to be output
to the LCD panel. There are three LCD panel types:
STN, DSTN, and TFT. There are four data bus widths
for output to the LCD panel: 4, 8, 12, and 16 bits. When
the required data bus width for a TFT panel is 16 bits or
more, connect the LCDC and LCD panel according to
the data bus size of the LCD panel. Unlike in a TFT
panel, in an STN or DSTN panel, the data bus width
setting does not have a 1:1 correspondence with the
number of display colors and display resolution, e.g., an
8-bit data bus can be used for 16 bpp, and a 12-bit data
bus can be used for 4 bpp. This is because the number
of display colors in an STN or DSTN panel is
determined by how data is placed on the bus, and not
by the number of bits. For data specifications for an
STN or DSTN panel, see the specifications of the LCD
panel used. The output data bus width should be set
according to the mechanical interface specifications of
the LCD panel.
If an STN or DSTN panel is selected, display control is
performed using a 24-bit space-modulation FRC
consisting of the 8-bit R, G, and B included in the
LCDC, regardless of the color and gradation settings.
Accordingly, the color and gradation specified by
DSPCOLOR is selected from 16 million colors in an
STN or DSTN panel. If a palette is used, the color
specified in the palette is displayed.
