Warning concerning stationary images on the TV screen

A characteristic of Plasma Display Panels is that displaying the same image for a long time can cause a permanent after-image to remain on the screen.This is called phosphor burn in.

Normal use of the TV should involve the showing of pictures that contain constantly moving and changing images that fill the screen.

Examples of stationary images (this is not an all-inclusive list, you may encounter others in your viewing):

TV and DVD menus: listings of DVD disk content;

Black bars: when black bars appear at the left and right side of the screen, it is recommended to change to a picture format so that the picture fills the entire screen;

PIP and Multipip: do not view for long periods of time using the PIP function or Multipip function;

TV channel logo: present a problem if they are bright and stationary. Moving or low-contrast graphics are less likely to cause uneven aging of the screen;

Stock market stickers: presented at the bottom of the TV screen;

Shopping channel logos and pricing displays: bright and shown constantly or repeatedly in the same location on the TV screen.

Examples of still pictures also include logos, computer images, time display, teletext and images displayed in 4:3 mode, static images or characters, etc.

Notes:

-reduce contrast and brightness when viewing

-once burn-in occurs it will never disappear completely.
