IMAGE RETENTION OF PLASMA DISPLAY  
There are different characteristics that result in panel image retention depending on how the plasma display is used.  
Situations and effective usage methods related to ghosting are provided below.  
Image retention characteristics of a plasma display  
The image retention phenomenon of a plasma panel occurs because of partial phosphor degradation arising from partial character and figure  
display.  
For example, when the character image as shown in Fig. A at the right is  
continuously displayed for a long period of time, the only part of the phosphor  
(Red,Green, Blue) that will degrade will be the color of the applicable character  
display portion. Consequently, when a white image is displayed on the entire  
screen as shown in Fig. a, the character marks displayed up to that time will  
become a color difference visible to the eye, but the phosphor will never burn.  
Fig. A  
Fig. a  
【 】  
【
】
The degree of image retention is proportional to the brightness of the characters and figures displayed as well as the display time.  
■
• The tendency of the phosphor is to degrade more the brighter the characters  
and figures are displayed. When images of figures with different levels of  
brightness, as shown in Fig. B, are continuously displayed for a long period of  
time, it becomes easier to see image marks at locations when the brighter  
figures are displayed to see.  
Fig. B  
Fig. b  
【 】  
【
】
The image retention images in this document are exaggerated for the purpose of explanation. The actual manner in which the image retention  
is seen differs depending on the operation time and brightness.  
*
Methods to Reduce the Occurrence of Image Retention  
• Lower the Contrast and Brightness settings of the plasma display as much as possible.  
A function is provided in the display that controls the brightness of the screen to reduce degradation of the panel. Using this function makes it  
possible to reduce image retention.  
(Refer to Panel Life (Extend 1.or Extend 2 shown on  
)
22  
• Set the plasma monitor to an “Screen Wipe” or “Inverse” display.  
The occurrence of image retention when displaying images of identical patterns, such as static images, for long periods of time can be  
reduced by displaying a reversed color or completely white screen for about 1 ~ 2 hours after terminating the display.  
(Settings can be made using Screen Wipe and Inverse of Function MENU shown on  
)
22  
• Using in combination with moving images  
Since the degradation of the fluorescent material progresses comparatively uniformly for moving images, the occurrence of partial image  
retention can be minimized by usage in combination with moving images such as DVDs.  
* Please be careful since image retention will occur if display is left in a two screen display state for a long period of time.  
* Television broadcasts include images displayed for long periods of time in which the left and right or top and bottom of the image are cut and  
broadcast station name or time are displayed in the same portion of the screen. Image retention in these portions can  
be expected to occur, so please be aware.  
NOTES  
About screen defects  
• High precision technology is used in the making of plasma panels but there may be dark spots (points that do not illuminate) and bright spots  
(points that are too bright) in some cases. These do not indicate a malfunction.  
About residual images  
• In some cases, residual images may remain after the short-term display of still images, but these will disappear and return to normalcy.  
This is not a malfunction.  
About the panel screen  
• Plasma displays create images by means of electrical discharges inside the panel. Because of this, the temperature of the panel surface may  
rise in some cases.Also, plasma displays are made of finely processed glass. A reinforced glass filter is installed over the panel surface but  
avoid strong impact because there is still danger of glass breakage.

CLEANING AND MAINTENANCE  
Cautions When Using the Plasma Display  
„ Do not bring your hands, face or objects close to the ventilation holes of the plasma dis-  
play. The top of plasma 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 damages to the object as well as the display itself.  
„ Be sure to disconnect all cables before moving the plasma display. Moving the display with its cables  
attached may damage the cables and thus case fire or electric shock danger.  
„ Disconnect the power plug from the wall outlet as a safety precaution before carrying out any type of clean-  
ing 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 is particular 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 fingers or hard objects of any kind.  
„ Do not use volatile substances such as insect 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 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 mois-  
ture gets inside the unit, operating problems, electrical and shock hazards may result.  
„ Do not scratch or hit the cabinet with fingers or hard objects of any kind.  
„ Do not use volatile substances such as insect sprays, solvents and thinners on the cabinet.  
„ Do not place articles made from rubber or PVC near the cabinet for any extended periods of time.  
Avoid Still Images  
„ Do not allow a still picture to be displayed for extended periods of time. This can cause a  
permanent image to remain on the plasma display. Examples of still images may include:  
still computer images, still video game images, still logos or pictures, text and images dis-  
played in 4:3 Normal mode.
