Philips Pixel Defect Policy
defects and several types of sub pixel defects within each category.
Bright Dot Defects Bright dot defects appear as pixels or sub pixels that are always lit or 'on'. That is,
a bright dot is a sub-pixel that stands out on the screen when the monitor displays a dark pattern.
There are the types of bright dot defects:
One lit red, green or blue sub
pixel
Two adjacent lit sub pixels:
- Red + Blue = Purple
- Red + Green = Yellow
- Green + Blue = Cyan (Light Blue)
Three adjacent lit sub pixels
(one white pixel)
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:
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.
