We strive to deliver the highest quality products and use some of the industry’s most advanced manufacturing processes whilst practicing stringent quality
control. However, pixel or sub-pixel defects on the PDP / TFT panels used in Plasma- & LCD- displays are sometimes unavoidable. No manufacturer can
guarantee that all panels will be free from pixel defects, but philips guarantees that any Plasma- & LCD- displays with an unacceptable number of defects
will be repaired during the warranty period in line with your local guarantee conditions.
This notice explains the different types of pixel defects and denes the acceptable defect level for the LCD screen. In order to qualify for repair under
warranty, the number of pixel defects must exceed a certain level as shown in the reference table. If the LCD screen is within specication a warranty
exchange / claim back will be refused. Additionally, because some types or combinations of pixel defects are more noticeable than others, philips sets even
higher quality standards for those.
8.1. Pixels and Sub-Pixels
subpixel
pixel
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.
8.2. Types of Pixel Defects + Dot Definition
Pixel and sub-pixel defects appear on the screen in different ways. There are three categories of pixel defects and several types of sub-pixel defects within
each category.
