The normal use of a TV should include a 

mixture of TV picture types.  The most fre-
quently used picture types should  ll the 
screen with constantly moving images rather 
than stationary images or patterns.  Dis-
playing the same stationary patterns over 
extended periods of time, or displaying the 
same stationary pattern frequently can leave 
a subtle but permanent ghost image.  To 
avoid this, mix your viewing pattern.  Do not 
show the same stationary image for more 
than 15% of your total TV viewing in any one 

week.  Display constantly moving and chang-

ing images that  ll the scr een wh enever  pos-
sible.

This projection TV uses picture tubes to proj-

ect the image to the screen.  All picture 
tubes age with use.  As they age, their 
light output is gradually reduced.  Normal 

TV pictures  ll the scr een wi th const ant ly 

changing images.  Under these conditions, 
picture tubes age at an even rate across 

the entire screen.  This maintains a TV pic-
ture that is evenly bright over the whole 
screen.  Stationary images or images that 
only partially  ll the scr een ( l eavi ng bl ack 
or colored bars to  ll the scr een) , wh en 
used over extended periods of time or when 

viewed repeatedly, can cause uneven aging 

of the phosphors and leave subtle ghosts of 
the stationary images in the picture.

Still or stationary images may be received 
from broadcasters, cable channels, satellite 

channels, DVD discs, video tapes, laser 
discs, on-line services, web/internet search-
ing devices, video games, and digital TV 
tuner/converter boxes.  Examples of these 
types of images can be, but are not limited 
to the following:

  Letterbox top/bottom black bars: 

shown at the top and bottom of the TV 
screen when you watch a widescreen 

(16:9) movie on a standard (4:3) TV.

  Side bar images: solid bars shown on 

each side of an image when watching a 

standard (4:3) program on a widescreen 

(16:9) TV.

  Stock-market report bars: ticker run-

ning at the bottom of the TV screen.

  Shopping channel logos & pricing dis-

plays: bright graphics that are shown con-

stantly or repeatedly in the same location.

  Video game patterns and scoreboards
  Bright station logos: moving or low-contrast 

graphics are less likely to cause uneven 
aging of the picture tubes.

  On-line (internet) web sites: or any 

other stationary or repetitive computer style 
images.
