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 def
ects appear as pix
els 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 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 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 TFT
LCD panel in a Philips flat panel monitor must
have pixel or sub pixel defects exceeding the
tolerances listed in the following tables.
