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 species tolerances for the
proximity of pixel defects.
Pixel Defect Tolerances
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.
Three adjacent lit sub pixels (one white
pixel).
Note
A red or bright blue dot must be
more than 50 percent brighter than
neighboring dots, while a bright
green 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'.
Meaning, 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.
