  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 
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.
