HANDLING FOR PLASMA DISPLAY PANEL
1.3.1 PRECAUTIONS DURING NOTES FOR TRANSPORTATION
When transporting the display unit, pressure exerted on the
internal PDP (Plasma Display Panel) due to improper handling
(such as tossing and dropping) may cause damages even when
the unit is carefully packed. To prevent accidents from occurring
during transportation, pay careful attention prior to delivery such
as through explaining the handling instructions to transporters.
Ensure that the following requirements are met during
transportation, as the PDP of this unit is made of glass and
therefore fragile:
(1) Avoid vibrations and impacts
The unit may be broken if it is toppled sideways even when
properly packed. Ensure that the unit is carried by at least
2 persons and pay careful attention not to exert any
vibration or impact on it.
(2) Do not place equipment horizontallyEnsure that it is placed
upright and not horizontally during transportation and
storage as the PDP is very vulnerable to lateral impacts
and may break easily under such circumstances.During
transportation, ensure that the unit is loaded along the
traveling direction of travel of the vehicle, and avoid
stacking them on one another.For storage, ensure that
they are stacked in 2 layers or less even when placed
upright.
1.3.2 RESIDUAL IMAGE / BURN-IN ON SCREEN
Like CRTs, ‘burn-ins’ may occur when a same image is
continuously displayed over an extended period of time.As Tthis
may also shorten the life span of the PDP. Therefore, turn off the
display when not in use, scroll the screen, make use of screen-
savers, or allow even distribution on the display by inverting the
brightness, switching to complementary colors or inserting
animated images at periodic intervals.As burn-in is more likely to
occur with high brightness and contrast settings, try to use
neutral gradations or medium tone colors.Burn-in does not occur
in the case of animated images.When switching to another
image after continuous display of the previous image, residual
images may become prominent, as luminance in a part of the
display is higher than the other parts. This is not a defect but is
because due to the discharge surface of the lighted portion has
becomebeing relatively activated and its luminance higher than
the unlighted parts.
1.3.3 INFRARED RAYS
Near Near-infrared rays (800nm to 1000nm) are emitted from the
front of the panel, and this may give rise to glitchescause
malfunctions in infrared remote controls or communication
systems placed near it. In this case, avoid direct infrared rays
(and reflected rays in some cases) from the screen by either
changing the direction of the unit or other infrared systems or
securing a longer keeping a distance from the screen.
1.3.4 OPTICAL FILTER (PANEL FILTER)
Avoid placing the unit under direct sunlight over a prolonged
period of time. This may cause the optical filter to deteriorate in
quality and color.Clean the filter surface by wiping it softly lightly
with outing flannels a soft and lightly fuzz cloth (such as
flannel).Do not use solvents such as benzine or thinner to wipe
the filter surface. This may cause the filter to deteriorate in quality
or the coating on the surface to come off.As Tthe filter surface is
fragile., Ddo not scratch or hit it with hard materials.
1.3.5 NOTES PRECAUTIONS FOR REPLACEMENT OF
EXTERIOR PARTS
Take note of the following when replacing exterior parts (back
REAR COVER, FRONT PANEL, optical filter):Do not exert
pressure on the front of the PDP (glass surface).Pay careful
attention not to scratch or stain the front of the PDP (surface) with
hands.When replacing exterior parts, the front of the PDP should
be placed facing downward. Place a mat, etc. underneath to
avoid causing scratches to the front surface.However, never use
materials that are too soft (such as blanket cloth). If replacement
is made with the PDP surface facing downward and in contact
with the blanket, pressure may be exerted on the PDP, thus
causing damages to it.
