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
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�
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�
