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:

One lit red, green or blue subpixel

Two adjacent lit subpixels:

- Red + Blue = Purple

- Red + Green = Yellow

- Green + Blue = Cyan (Light Blue)

Three adjacent lit subpixels (one white pixel)

Black Dot Defects

Black dot defects appear as pixels or subpixels that are always dark or "off". These are the types of black dot defects:

One dark subpixel Two or three adjacent dark subpixels

Proximity of Pixel Defects

Because pixel and subpixels defects of the same type that are nearby one 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 during the warranty period, a TFT LCD panel in a Philips flat panel monitor must have pixel or

subpixel defects exceeding the tolerances listed in the following tables.
