Philips Pixel Defect Policy
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.
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.
