certain area continuously, as the feature of LCD panel. This is caused due to brightness degradation.

Once image retention occurs, use the mode that displays more motion pictures. It will help reduce this
matter.
3. Solution

* The permanent image sticking could not take off under the latest technology.
This method may be used to eliminate a temporary retained image that occurs after displaying a still
image for a certain period of time. Since it may take several minutes to several hours to remove image
sticking, it is recommendable to display motion pictures during 2~3 minutes every hour when keeping
displaying a still image. As image sticking is influenced by the brightness of a still image being
displayed and its display time, it is recommended that you reduce the brightness of the screen when
displaying a still image for a long time.
* Image Sticking does not come under the warranty.
