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 practice stringent quality
control. However, pixel or subpixel 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 subpixels on a 15" XGA monitor may be defective. Additionally, because some types or combinations of pixel defects are more noticeable than others,
Philips sets even higher quality standards for those.
Pixels and Subpixels
A pixel, or picture element, is composed of three subpixels in the primary colors of red, green and blue. Many pixels together form an image. When all
subpixels of a pixel are lit, the three colored subpixels together appear as a single white pixel. When all are dark, the three colored subpixels together appear
as a single black pixel. Other combinations of lit and dark subpixels appear as single pixels of other colors.
