[Elecraft] P3 burn-in concerns?

[david Moes]

That would depend if the backlight is LED or cold cathode.     I service 
equipment with LCD displays with both types of backlights and burnout is 
very very rare.   on small screens like the P3 the light is not being 
pushed hard and should last a long long time.

As for burn in.   One of our machines with a 14 inch LCD display does in 
fact burn in.    It takes a many months  of displaying the same image 
24/7.  The customer never sees the burn as that part of the screen never 
changes.  but with the different screens I use in diagnostics I can see 
it.     If I leave it on a full white screen over night it disapears and 
doesnt seem to come back for another several months so the burn in seems 
to not be permanent.      on the P3 I doubt this will ever be an issue.
