The FP connects to the RGB port of the video mixer.
LCD Interface
The FP interfaces directly to industry standard 18-bit or 24-
bit active matrix thin-film-transistor (TFT). The digital RGB
or video data that is supplied by the video logic is con-
verted into a suitable format to drive a wide variety range of
panels with variable bits. The LCD interface includes dith-
ering logic to increase the apparent number of colors dis-
played for use on panels with less than 6 bits per color. The
LCD interface also supports automatic power sequence of
panel power supplies.
Mode Selection
The FP can be configured for operation with most standard
TFT panels:

• Supports TFT panels with up to 24-bit interface with
Table 6-66 shows the mapping of the data in the supported
modes.
For TFT panel support, the output from the dither block is
directly fed on to the panel data pins (DRGBx). The data
that is being sent on to the panel data pins is in sync with
the TFT timing signals such as HSYNC, VSYNC, and LDE.
One pixel (or two pixels in 2 pix/clk mode) is shifted on
every positive edge of the clock as long as DISP_ENA is
active.
640x480, 800x600, 1024x768, 1280x1024, and
1600x1200 pixel resolutions. Either one or two pixels per
clock is supported for all resolutions. Other resolutions
below 640x480 are also supported.
