Interfacing with an Unmatched Number
of Display RGB Lines
It is possible that the display controller ’s number of
RGB line outputs is different from the number of RGB
line inputs of the display; it is still possible to interface
both of them. If the display’s RGB input lines are equal
to the display controller ’s RGB line outputs, there will
be no color degradation. If not, there may be a slight
color degradation because the display panel will be
unable to display all the colors generated by the display
controller. Usually, the former case is encountered
rather than the latter.
In Figure 15 , the display panel has more RGB signal
lines than the display controller. Here, all the RGB lines
of each color of the display controller are connected to
the MSbs of the display’s display signal lines. The
unconnected LSbs may be connected to Ground or
V DD , or to the MSb of the same color. Connecting the
LSbs to the MSbs is the widely used method, since this
enables the display to have a wider range of color
values.
