Meridian 1

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