Types of Pixel Defects
Pixel and sub pixel defects appear on the screen in different ways. There are two categories of pixel 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'. These are the
types of bright dot defects:
One lit red, green or blue
subpixel
Black Dot Defects Black dot defects appear as pixels or sub pixels that are always dark or 'off'. These are the
types of black dot defects:
One dark subpixel

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.
