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.
