I always thought not, but Richer Sounds emailed me with an offer for the Samsung 32 QLED 'frame', with this comment in the description -
"Sit back and imagine a beautiful TV that allows you to display artwork or your own photos with ease. Select the art pieces you want to see and set the time on how long you want it to be shown on screen. "
Hmm, what about screen burn ?, or is the selected time per photo limited to the time that won't do any damage ?.

Samsung USA offer a 10 year guarantee against burn-in so must be fairly confident it isn't a major problem for QLED screens.
The guarantee is against "TV burn-in" I wonder if that excludes "PC burn-in"?
The way they work I think with LCD display technology burn in is virtually impossible.
With OLED it might be possible, but I'd honestly be more worried about it being left in bright sunlight and UV damage from incident light. I expect they do have a protective filter against UV on the front.
Old CRT computer monitors used to get very bad screen burn. Login: Login:
was etched into the phosphor on every line especially the top one.
Did wonder if Q-LED was any different to other LED backlit LCDs.
But given my O-LED is programmed to avoid damage to the LEDs, surely a Q-Led would be too - if a problem?
It's a dig at OLED - LEDs don't exhibit burn-in (with OLED it's actually 'burn-out - i.e. the red pixels get fainter). I've a QLED and it's a v. good picture, v. low reflection and holds well to about 70 deg. off centre.
And USA-only guarantee too
First I've heard of it, unless you are going to be silly and display one picture for hours on end. Even CRTs did not like that one. Brian
The Samsung is QLED not OLED not sure of the difference., They have burn-in protection and blank the screen if a static picture is displayed. So if I am streaming a radio station the screen blanks after a while.

QLED should have wear characteristics more like an LCD screen then.
CRTs were very vulnerable to screen burn. Most of the computer centre's monitors had "Login:" burned into the top left corner and copies of the same gradually fading all of the way down the left hand side.
I have yet to see an LCD screen with significant (as in easily visible in normal use) screen burn damage. The technology involved alternating currents to alter the pixel brightness so there is no direct harm.
(applying DC for extended periods can harm an LCD display)
Q-LED is basically LCD with LED backlight - same as many have been for ages. Difficult to find out the true difference if any beyond the hype.
