Philips 180MT manual Proximity of Pixel Defects, Pixel Defect Tolerances

Philips Pixel Defect Policy

	Two adjacent lit sub pixels:	Three adjacent lit sub pixels
One lit red, green or blue sub	- Red + Blue = Purple
pixel	- Red + Green = Yellow	(one white pixel)
	- Green + Blue = Cyan (Light Blue)

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.

BRIGHT DOT DEFECTS	ACCEPTABLE LEVEL
MODEL	150MT	180MT
1 lit sub pixel	4 or fewer	3 or fewer
2 adjacent lit sub pixels	2 or fewer	2 or fewer
3 adjacent lit sub pixels (one white pixel)	0	0
Distance between two bright dot defects*	15 mm or more	15mm or more
Bright dot defects within 20 mm circle	3 or fewer	-
