SAFETY INSTRUCTIONS
IMPORTANT: Always activate a moving screen saver program when you leave your display
unattended. Always activate a periodic screen refresh application if the unit will display unchanging
static content. Uninterrupted display of still or static images over an extended period may cause
“burn in”, also known as “after-imaging” or “ghost imaging”, on your screen. This is a well-known
phenomenon in LCD panel technology. In most cases, the “burned in” or “after-imaging” or “ghost
imaging” will disappear gradually over a period of time after the power has been switched off.
WARNING: Severe “burn-in” or “after-image” or “ghost image” symptoms will not disappear and
cannot be repaired. This is also not covered under the terms of your warranty.
Service:
• The casing cover should be opened only by qualied service personnel.
• If there is any need for repair or integration, please contact your local service center.
• Do not leave your display under direct sunlight.
If your display does not operate normally, having followed the instructions set out in
this document, please contact a technician or your local service center.
Read and follow these instructions when connecting and using your display:
• Unplug the display if you are not going to use it for an extensive period of time.
• Unplug the display if you need to clean it with a slightly damp cloth. The screen
many be wiped with a dry cloth when the power is off. However, never use alcohol,
solvents or ammonia-based liquids.
• Consult a service technician if the display does not operate normally when you
have followed the instructions in this manual.
• The casing cover should be opened only by qualied service personnel.
• Keep the display out of direct sunlight and away from stoves or any other heat
sources.
• Remove any object that could fall into the vents or prevent proper cooling of the
display’s electronics.
• Do not block the ventilation holes on the cabinet.
• Keep the display dry. To avoid electric shock, do not expose it to rain or excessive
moisture.
• When turning off the display by detaching the power cable or DC power cord, wait
for 6 seconds before re-attaching the power cable or DC power cord for normal
operation..
• To avoid the risk of shock or permanent damage to the set do not expose the
display to rain or excessive moisture.
• When positioning the display, make sure the power plug and outlet are easily
accessible.
• IMPORTANT: Always activate a screen saver program during your application. If a
still image in high contrast remains on the screen for an extended period of time,
it may leave an ‘after-image’ or ‘ghost image’ on the front of the screen. This is
a well-known phenomenon that is caused by the shortcomings inherent in LCD
technology. In most cases the afterimage will disappear gradually over a period of
time after the power has been switched off. Be aware that the after-image symptom
cannot be repaired and is not covered under warranty.

CHAPTER 8: PIXEL DEFECT POLOCY
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 we guarantee
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, We set 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.
Dot denition = What is a defective “Dot”? :
One or more defective, adjacent sub-pixel are dened as one “dot”. The no. 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.
RR G B
One dot = One Pixel; consists of three sub-pixels of Red, Green, and Blue.
8.3 Bright Dot Defects
Bright dot defects appear as pixels or sub-pixels that are always lit or “on”. These are the examples
of bright dot defects:
45
PIXEL DEFECT POLOCY
One lit red, green or blue sub
pixel
Two adjacent lit sub pixels:
Red + Blue = Purple
Red + Green = Yellow
Green + Blue = Cyan (Light
Blue)
Three adjacent lit sub pixels
(one white pixel)
8.4 Dark Dot Defects
Black dot defects appear as pixels or sub-pixels that are always dark or “off”. These are the
examples of black dot defects:
One dark dotTwo adjacent dark dots = 1
pair of dark dots
Two dark dots, specications
denes the minimum distance
between dark dots
8.5 Proximity of Pixel Defects
Because pixel and sub-pixels defects of the same type that are nearby one another may be more
noticeable, We also specify 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 dots
• Total no. of all defective dots
8.6 Pixel Defect Tolerances
In order to qualify for repair due to pixel defects during the warranty period, a PDP / TFT panel in a
Plasma / LCD- display must have pixel or sub-pixel defects exceeding the tolerances listed in the
following table.
46
PIXEL DEFECT POLOCY
BRIGHT DOT EFFECT ACCEPTABLE LEVEL
1 lit sub pixel 2
BLACK DOT EFFECT ACCEPTABLE LEVEL
1 dark sub pixel 10
TOTAL DOT DEFECTS OF ALL TYPES 12
NOTE: * 1 or 2 adjacent sub pixel defects = 1 dot defect
8.7 MURA
Dark spots or patches may occasionally appear on some liquid crystal display (LCD) panels. This
is known within the industry as Mura, which is a Japanese term for “unevenness.” It is used to
describe an irregular pattern or area in which uneven screen uniformity appears under certain
conditions. Mura is a result of the deterioration of the liquid crystal alignment layer and is most
commonly caused by long-term operation under high ambient temperatures. It is an industry- wide
phenomenon and Mura is not repairable. It is also not covered by our warranty terms.
Mura has been around since the introduction of LCD technology and with screens getting bigger
and in operation 24/7, many displays are running in low light conditions. This all adds to the
possibility of Mura affecting displays.
HOW TO SPOT MURA
There are many symptoms of Mura and also multiple causes. Several of these are listed below:
• Impurities or foreign particles in the crystal matrix
• Uneven distribution of LCD matrix during manufacturing
• Non-uniform luminance distribution of the backlight
• Panel assembly induced stress
• Flaws within the LCD cells
• Thermal induced stress - high temperature operation over long periods of time
HOW TO AVOID MURA
Although we can not guarantee the complete eradication of Mura every time, in general the
appearance of Mura can be minimized by these methods:

9.1 Cleaning
Caution When Using the Display
• Do not bring your hands, face or objects close to the ventilation holes of the display. The top
of the display is usually very hot due to the high temperature of exhaust air being released
through the ventilation holes. Burns or personal injuries may occur if any body parts are
brought too close. Placing any object near the top of the display could also result in heat
related damage to the object as well as the display itself.
• Be sure to disconnect all cables before moving the display. Moving the display with its cables
attached may damage the cables and thus cause re or electric shock.
• Disconnect the power plug from the wall outlet as a safety precaution before carrying out any
type of cleaning or maintenance procedure.
Front Panel Cleaning Instructions
• The front of the display has been specially treated. Wipe the surface gently using only a
cleaning cloth or a soft, lint-free cloth.
• If the surface becomes dirty, soak a soft, lint-free cloth in a mild detergent solution. Wring the
cloth to remove excess liquid. Wipe the surface of the display to remove dirt. Then use a dry
cloth of the same type to dry.
• Do not scratch or hit the surface of the panel with ngers or hard objects of any kind.
• Do not use volatile substances such as insert sprays, solvents and thinners.
Cabinet Cleaning Instructions
• If the cabinet becomes dirty, wipe the cabinet with a soft, dry cloth.
• If the cabinet is extremely dirty, soak a lint-free cloth in a mild detergent solution. Wring the
cloth to remove as much moisture as possible. Wipe the cabinet. Use another dry cloth to
wipe over until the surface is dry.
• Do not allow any water or detergent to come into contact with the surface of the display. If
water or moisture gets inside the unit, operating problems, electrical and shock hazards may
result.
• Do not scratch or hit the cabinet with ngers or hard objects of any kind.
• Do not use volatile substances such as insert sprays, solvents and thinners on the cabinet.
• Do not place anything made from rubber or PVC near the cabinet for any extended periods of
