Pioneer PRO-FHD1 operating instructions Panel sticking and after-image lag, Image Retention

01Important User Guidance Information

CAUTION

Panel sticking and after-image lag

•Displaying the same images such as still images for a long time may cause after-image lagging. This may occur in the following two cases.

1After-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.

2After-image (lag image) due to burning

Avoid displaying the same image on the Plasma Display continuously over a long period of time.

This includes those images displayed in the following screen modes: multiscreen function, screen size 4:3, screen size FULL 14:9, screen size CINEMA 14:9, screen size Dot by Dot (except when the input size is 1920x1080), and images with black bands at top/bottom or right/left.

If the same image is displayed continuously for several hours, or for shorter periods of time over several days, a permanent after-image may remain on the screen due to burning of the fluorescent materials. Such images may become less noticeable if moving images are later displayed, but they will not disappear completely.

•The energy save function can be set to help prevent damage from screen burning (see page 29).

Image Retention

When a static image is left frozen on a display for several hours, a faint imprint of the image, known as image retention, can remain. This image retention may be temporary or permanent. Although caused by different things, image retention can occur on all display technologies, including plasma and LCD. On today’s plasma displays, permanent image retention is less of a worry. Most image retention can be improved simply by watching moving video.

Image retention, also known as burn-in, can occur in all phosphor-based display systems (including CRT television systems -both direct view and projection- as well as plasma display systems). Displaying the same still images for long periods should be avoided as permanent image retention or burn-in may occur. Recommended guidelines are as follows:

Do not display static images for long periods (such as still images, fixed images from PC or TV game equipment, and/or fixed images such as time of day indicator or channel logo display).

Do not display content in the 4:3 aspect ratio (black or gray bars on left and right side of content) or letter-box content (black bars above and below content) for extended periods of time, or use either of these viewing modes repeatedly within a short period of time. This plasma display system is equipped with multiple wide-screen viewing modes; use one of these screen modes to fill the entire screen with content.

Displaying dark images after displaying still images for a period of time may cause image retention. In most cases, the image retention can be corrected by displaying bright images for a similar period of time.

If you display still images on your plasma display system for long periods of time, image retention may be irreparable.
