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.
