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
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 225P2/225PL2
1 lit subpixel 3
2 adjacent lit subpixels 1
3 adjacent lit subpixels (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 225P2/225PL2
1 dark subpixel 5 or fewer
2 adjacent dark subpixels 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 225P2/225PL2
Total bright or black dot defects of all types 5 or fewer
Note
1 or 2 adjacent sub pixel defects = 1 dot defect
This monitor is ISO9241-307 compliant.
