(backlight life)
Backlight life is designated as the number of hours until the brightness drops to half
of the maximum level, in a 25°C environment. Before leaving images on the display
for an extended period of time, turn the backlight off if at all possible.
For information about how to replace the backlight, see "7-2 Replacing the 100V
Unit's Backlight."
l l Display Colors
• Uneven brightness, flickering, or ghosts (caused by cross talk) may occur with the
PL-5700S1, PL-5701S1, PL-5700L1, and PL-5701L1, depending on the display col-
ors (especially halftones) or color combinations used. This, however, is a basic char-
acteristic of this type of display, not a defect. Since this flickering can sometimes be
caused by the combination of display colors used, selecting other colors may improve
the display quality.
• The higher the contrast between the foreground and background colors is, the more
likely that crosstalk will occur. Either changing the color combination or decreasing
the contrast may help to reduce the amount of cross talk.
See "5-2, System Parameters."
