Specifications
I I For black-and-white displays : the PL-5700L1 and the PL-5701L1
• These displays normally use only black and white,
with grey tones being produced by making the dots
flash. This display method, however, may cause flick-
ering to occur with certain halftones.
• If VGA 16-color standard pallet colors are used on a
black-and-white display, brightness will increase in
order of the pallet numbers, i.e. from 0 (black) to 15
(white). It is not recommended to use those colors
marked with asterisks (*) (shown in the figure to the
right), since they often cause flickering.
• Pallet colors 2, 6, and 9 may be hard to identify on
the screen, since they have almost the same level of
brightness.
• Some combinations of colors may not be easy to iden-
tify. Whenever you are developing an application it
is recommended that you frequently test how your
program will appear on the PL.
• Black-and-white tiled displays often appear better
than multi-colored displays.
• If you wish to use halftones, be sure to check their
display quality during actual PL operation.
I I I STN color LCD displays: PL-5700S1 and PL-5701S1
• STN color LCDs use three primary colors - red, green, and blue - to display up to
8 different colors. Halftones are produced by making the dots used in these three
colors flash. This mechanism, however, may cause flickering with certain half-
tones.
• Tiled displays using only pure colors - black, red, green, blue, yellow, magenta,
cyan, and white (pallet numbers 0, 12, 10, 9, 14, 13, 11, and 15) - may appear
better than displays using different colors.
• If you wish to use halftones, be sure to check their display quality during actual
PL operation.
