Philips' Flat Panel Monitors Pixel Defect Policy

Philips strives to deliver the highest quality products. We use some of the industry's most advanced

manufacturing processes and practise 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. For

example, no more than 0.0004% of the sub pixels on a 15" XGA monitor may be defective. Furthermore,

Philips sets even higher quality standards for certain types or combinations 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 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.
