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
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 |
