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 can guarantee that any Plasma & LCD
displays with an unacceptable number of defects will be repaired during the warranty period in line with
your local warranty
This notice explains the different types of pixel defects and denes the acceptable defect level for the
LCD screen. 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 or claim
will be denied.
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
Dot denition = What is a defective “Dot”?
Black dot defects appear as pixels or sub-pixels that are always dark or “off.” These are the examples of
black dot defects:
Because pixel and sub-pixel defects of the same type that are nearby one another may be more
noticeable, there are specic tolerances for the proximity of pixel defects. In the table below you can nd
specications about
Allowed amount of adjacent dark dots (adjacent dark dots = 1 pair of dark dots
Minimum distance between dark dot
Total number of all defective dots
One or more defective, adjacent sub-pixel
are dened as one “dot”. The number of
defective sub-pixels are not relevant to
dene a defective dot. This means that a
defective dot can consist of one, two or
three defective sub-pixels which can be
dark or lit.
One dot = One Pixel; consists
of three sub-pixels of Red,
Green, and Blue.

ity of Pixel Defects
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.
