7. Customer care and warranty
Three adjacent lit sub pixels (one white
pixel).
Note
A red or blue bright dot must be more
than 50 percent brighter than neighboring
dots while a green bright dot is 30 percent
brighter than neighboring dots.
Black Dot Defects
Black dot defects appear as pixels or sub
pixels that are always dark or 'o'. That is,
a dark dot is a sub-pixel that stands out on
the screen when the monitor displays a
light pattern. These are the types of black
dot defects.
Proximity of Pixel Defects
Because pixel and sub pixels defects of the
same type that are near to one another
may be more noticeable, Philips also
species tolerances for the proximity of
pixel defects.
Pixel Defect Tolerances
In order to qualify for repair or
replacement due to pixel defects during
the warranty period, a TFT Monitor panel
in a Philips at panel monitor must have
pixel or sub pixel defects exceeding the
tolerances listed in the following tables.
