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 'off'.
That is, a dark dot is a sub-pixel that stands out
on the screen when the monitor displays a light
pattern.
These are some 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 specifies 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 Philips flat monitor panel must have pixel or
sub pixel defects exceeding the tolerances listed
in the following tables.
