Pixel and subpixel defects appear on the screen in different ways. There are two categories of pixel defects and several types of subpixel defects within each 
category. 

 

 
Bright Dot Defects

  

Bright dot defects appear as pixels or subpixels that are always lit or "on". These are the types of bright dot defects:

 

 

 

 

One lit red, green or blue subpixel

 

Two adjacent lit subpixels: 

- Red + Blue = Purple 

- Red + Green = Yellow 

- Green + Blue = Cyan (Light Blue)

Three adjacent lit subpixels (one white pixel)

 
 
Black Dot Defects  

Black dot defects appear as pixels or subpixels that are always dark or "off". These are the types of black dot defects:

 

 

 

One dark subpixel

 

Two or three adjacent dark subpixels

 

 
Proximity of Pixel Defects 

 

Because pixel and subpixels defects of the same type that are nearby one another may be more noticeable, Philips also specifies tolerances for the proximity 
of pixel defects.
