Important Information for
Preventing Image Retention
OLED is a self-emissive technology, which brings many
significant benefits to image quality and performance.
As with any self-emitting display, it is possible for users
of OLED TVs to experience temporary image retention
under certain conditions, such as when displaying
a static image on the screen for a long time. Even
so, this phenomenon is rare under ordinary viewing
conditions and is not a malfunction. Below sets forth
helpful information you may refer to for using your
OLED TV.
Examples of Images that may Cause
Image Retention
•
Still images or fixed images containing certain
information that are displayed uninterrupted
on the screen, such as channel numbers, station
logos, program titles, news or movie subtitles, and
headlines.
•
Fixed menu or icons for video game consoles or
broadcasting set-top boxes.
•
Black bars shown on the left, right, top, or bottom of
the screen, such as in images with a 4:3 or 21:9 ratio.
Recommended Measures for
Preventing Image Retention
•
Avoid watching a video displaying an image as listed

Information on Functions
Supporting Image Quality in Relation
to Temporary Image Retention
•
OLED TV offers a function called Pixel Refresher,
which helps to prevent temporary image retention.
This function can be operated automatically or
manually.
•
The auto feature will activate when the TV power
is turned off, but only after the TV has been turned
on for a cumulated total of four (4) hours or more,
which need not be consecutive. Pixel Refresher
will automatically run for several minutes after the
screen is turned off. (Please note that failure to
supply the AC power or disconnecting the power
cord from the outlet will disable the auto feature.)
•
To manually activate Pixel Refresher, you will have
to select [Picture] [OLED Panel Settings] [Pixel
Refresher] in the settings. Once manually activated,
the function will run for approximately one (1) hour.
During this time, a horizontal line may appear on the
screen; however, this is not a malfunction.
•
If Pixel Refresher has not been manually activated for
a certain period of time, a pop-up window advising
to activate this function will appear on the screen.
Please follow the instructions set forth in the pop-up
window.
•
In addition to Pixel Refresher, there are other
functions available for protecting the screen from
image retention. For example, a function that
automatically reduces the screen brightness level,
in part or in whole, will be activated when a static
image is displayed uninterrupted on the screen.
Once the static image disappears, the brightness
level will automatically return to the previous level.
This function is an intended function, and not a
malfunction.
