7. Customer care and warranty

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 Monitor 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

1 lit subpixel 3

2 adjacent lit subpixels 1

3 adjacent lit subpixels (one white pixel) 0

Distance between two bright dot defects* >15mm

Total bright dot defects of all types 3

BLACK DOT DEFECTS ACCEPTABLE LEVEL

1 dark subpixel 5 or fewer

2 adjacent dark subpixels 2 or fewer

3 adjacent dark subpixels 0

Distance between two black dot defects* >15mm

Total black dot defects of all types 5 or fewer

TOTAL DOT DEFECTS ACCEPTABLE LEVEL

Total bright or black dot defects of all types 5 or fewer
