Philips 201EL1SB/00 user manual Proximity of Pixel Defects

Philips Pixel Defect Policy

sub-pixel that stands out on the screen when the monitor displays a dark pattern. There are the types of bright dot defects:

Two adjacent lit sub pixels: - Red + Blue = Purple

One lit red, green or blue sub pixel - 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.
