Philips Pixel Defect Policy

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 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

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.

Types of Pixel Defects

Pixel and sub pixel defects appear on the screen in different ways. There are two categories of pixel

defects and several types of sub pixel defects within each category.

Bright Dot Defects Bright dot defects appear as pixels or sub pixels that are always lit or 'on'. That is,

a bright dot is a sub-pixel that stands out on the screen when the monitor displays a dark pattern.

There are the types of bright dot defects:

Three adjacent lit sub pixels

(one white pixel)

* A red or blue bright dot must be more than 50 percent brighter than neighboring dots

while a green bright dot is 30 percent brighter than neighboring dots.
