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.

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.
