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 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.
Note:
1. 1 or 2 adjacent sub pixel defects = 1 dot defect.
2. This monitor is ISO9241-307 compliant, Class-I compliant.(ISO9241-307: Ergonomic requirement , analysis and
compliance test methods for electronic visual displays)
3. ISO9241-307 is the successor of formerly known ISO13406 standard, which is withdrawn by the International
Organisation for Standardisation (ISO) per: 2008-11-13.
