Philips Pixel Defect Policy
Philips Flat Panel Monitors Pixel Defect Policy
Philips strives to deliver the highest quality products. We use some of \
the industrys most advanced 
manufacturing processes and practice stringent quality control. However,\
 pixel or sub pixel defects on the 
TFT LCD panels used in flat panel monitors are sometimes unavoidable. No\
 manufacturer can guarantee 
that all panels will be free from pixel defects, but Philips guarantees \
that any monitor with an unacceptable 
number of defects will be repaired or replaced under warranty. This noti\
ce explains the different types of 
pixel defects and defines acceptable defect levels for each type. In ord\
er to qualify for repair or replacement 
under warranty, the number of pixel defects on a TFT LCD panel must exce\
ed these acceptable levels. For 
example, no more than 0.0004% of the sub pixels on a 19W XGA monitor ma\
y be defective. Furthermore, 
Philips sets even higher quality standards for certain types or combinat\
ions of pixel defects that are more 
noticeable than others. This policy is valid worldwide. 
Pixels and Sub pixels 
A pixel, or picture element, is composed of three sub pixels in the prim\
ary colors of red, green and blue. 
Many pixels together form an image. When all sub pixels of a pixel are l\
it, the three colored sub pixels 
together appear as a single white pixel. When all are dark, the three co\
lored sub pixels together appear as a 
single black pixel. Other combinations of lit and dark sub pixels appear\
 as single pixels of other colors.
 
 
Types of Pixel Defects 
Pixel and sub pixel defects appear on the screen in different ways. Ther\
e 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 o\
r on. That is, a 
bright dot is a sub-pixel that stands out on the screen when the monitor displays \
a dark pattern. There are 
three types of bright dot defects:

Philips Pixel Defect Policy
 
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. There are two 
types of black dot defects:
One dark sub pixelTwo or three adjacent dark sub pixels
Proximity of Pixel Defects 
Because pixel and sub pixels defects of the same type that are near to o\
ne another may be more 
noticeable, Philips also specifies tolerances for the proximity of pixel\
 defects. 
 
Pixel Defect Tolerances
In order to qualify for repair or replacement due to pixel defects durin\
g the warranty period, a TFT LCD 
panel in a Philips flat panel monitor must have pixel or sub pixel defec\
ts exceeding the tolerances listed in 
the following tables.
