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.
Types of Pixel Defects
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:
