ABOUT PLASMA DISPLAY PANEL
Image Retention of Plasma Display Panel
The plasma display panel has one of characteristics that can result in panel image retention depending on how the
plasma display is used. The following are the common reasons for and effective preventive measures against the
image retention.
Characteristics of Image Retention
Image retention is caused by partial degrading the phosphors due
to the partial display of character and fi gure.
For example, when the characters as shown in Fig. A are displayed
continuously for a long period of time, only the phosphors (Red/Green/
Blue) displaying the characters are degraded. Consequently, when
displaying an all white image on the entire screen as shown in Fig. a,
the marks remaining by the characters will show colour differences;
therefore, note that it is not burnt remains of the phosphors.
The degree of image retention is proportional to the Brightness
and Display Time for the characters and/or fi gures.
The brighter the characters and fi gure, the more phosphor is
degraded. As shown in Fig. B, in case of displaying images that
have different brightness each for a long time, Fig. b shows that
the brighter the image, the more it tends to remain.
* The illustrations are images to explain image retention. The actual manners on the image retention vary depending
on such conditions as operation time and brightness.
Method to Reduce Image Retention
Use “Screen Wipe” or “Luminance Manager” functions on the display, which are available from Confi guration
menu. (Refer to
30
,
31
.)
After displaying certain images such as a still image for a long time, “Screen Wipe” can be used to reduce the
image retention by displaying a completely white screen for about 1~2 hours. In addition, “Luminance Manager
function works when displaying images such as TV station logos or clock displays in the corners of the screen.
Use in combination with moving images.
Since the entire screen has relatively even degradation of the phosphor in moving images, it can reduce the partial
image retention. We recommend to use together with such moving images as DVD.
Please be careful that leaving the images in 2-picture mode for a long period of time can cause image retention.
Some television broadcasts contain images of which cut the left/right or top/bottom, and in which broadcast station
identity or a clock is displayed for a long time at the same position. Please be aware that it may cause the image
retention.
Common Characteristics of Plasma Display Panels
The following are the common characteristics of Plasma Display Panel due to structural reasons.
Please note that they are not malfunctions.
Residual image
When a still image or menu is displayed on the screen for a short time (about a minute) and then switches to another
image, it may leave an “after-image” on the screen.
The residual image will disappear on its own.
Surface on Panel
The plasma panel displays images by generating discharges internally. This could raise the temperature of the display surface.
In addition, do not allow any forceful impact to the surface of panel because plasma panel is fi ne-processing glass
even though the panel strengthens by the front fi lter made of tempered glass.
Defective Pixels on Panel
The plasma display panel is manufactured with high-precision technology. However, there might be some pixels that
do not light, are brighter than the others, or in different colours, etc.
