Important Tip

Image Retention Effect (Image Sticking)

1. Cause :

-Image Retention Effect may come from displaying a still picture in certain period of time with at a certain area continuously, as the feature of PDP panel. This is caused due to brightness degradation. Many PDP manufacturers are trying to overcome this limitation.

2. Prevention

-To avoid this matter, use the product after reducing brightness and contrast, especially when a still image is displaying for a long time. (Contrast 50/Brightness 50 - See 30 page)

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

3. Solution

-The temporary image sticking would decrease with displaying Full-White pattern during 10 hours.

*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.
