Black Dot Defects Black dot defects appear as pixels or sub pixels that are always dark or 'off'. These are
the types of black dot defects:
One dark sub pixel Two or three adjacent dark sub pixels
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

panel in a Philips flat panel monitor must have pixel or sub pixel defects exceeding the tolerances listed in
the following tables.
