::LCD pixels kept in the same state on an LCD don't wear out and

Surprisingly this does happen. Amongst the varied things I repair are LCD=20
monitors from the gaming industry, it is not unusual to see monitors with=20
the game wheels burnt into them. I was amazed when I first saw this!

True these machines are switched on 18 hours a day 365 days a year, whilst=

this mainly occurs in monitors that have been in machines for 5 years or=20
so, I have seen it in monitors as young as 3 years old.

In most cases it could be put down to the backlight being at it's highest=20
level and the amount of heat generated by the machines  not helped by the=20
glass in front of the LCD, but there are some monitors that have a toned=20
down backlight and still manage to have screen burn.

LCD's are standard Samsung or LG 19" panels.
