ENGLISH ADDITIONAL INFORMATION About the plasma panel's protection function The brightness of this display will deteriorate slightly when an image with little movement such as a photograph or computer image is continuously displayed. This is caused by the plasma panel's protection function which detects images with slight movement and automatically adjusts brightness to protect the display, and is not a malfunction. This function starts approximately 5 minutes after the power has been turned on or after input has been switched.

This may occur in the following two cases. 1. After-image lagging due to remaining electrical load When image patterns with very high peak luminance are displayed for more than 1 minute, after-image lagging may occur due to the remaining electric load. The after-images remaining on the screen will disappear when moving images are displayed. The time for the after-images to disappear depends on the luminance of the still images and the time they had been displayed. 2. After-image lagging due to sticking Avoid displaying the same images continuously over a long period of time with the Plasma Display. When images of the same pattern are displayed continuously for several hours or displayed for a short period of time every day, after-images may remain on the screen due to the sticking of the fluorescent materials. In this case, these images may decrease if moving images are displayed after them, but basically they will not disappear.
