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.
BRIGHT DOT DEFECTS ACCEPTABLE LEVEL
MODEL 192E2/192EL2
1 lit subpixel 3
2 adjacent lit subpixels 1
3 adjacent lit subpix
els (one white pixel) 0
Distance between two bright dot defects* >15mm
Total bright dot defects of all types 3
BLACK DOT DEFECTS ACCEPTABLE LEVEL
MODEL 192E2/192EL2
1 dark subpixel 5 or fewer
2 adjacent dark subpix
els 2 or fewer
3 adjacent dark subpixels 0
Distance between two black dot defects* >15mm
Total black dot defects of all types 5 or fewer
TOTAL DOT DEFECTS ACCEPTABLE LEVEL
MODEL 192E2/192EL2
Total bright or black dot defects of all types 5 or fewer
Note
1 or 2 adjacent sub pixel def
ects = 1 dot defect
