Philips Pixel Defect Policy
Philips Pixel Defect Policy
Philips strives to deliver the highest quality products. We use some of the industry's 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 notice explains the different types of pixel defects and defines
acceptable defect levels for each type. In order to qualify for repair or replacement under
warranty, the number of pixel defects on a TFT LCD panel must exceed these acceptable levels.
This policy is valid worldwide.
Pixels and Sub pixels
A pixel, or picture element, is composed of three sub pixels in the primary colors of red, green
and blue. Many pixels together form an image. When all sub pixels of a pixel are lit, the three
colored sub pixels together appear as a single white pixel. When all are dark, the three colored
sub pixels together appear as a single black pixel. Other combinations of lit and dark sub pixels
appear as single pixels of other colors.
