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

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.
