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 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 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)
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 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.
