When OLED screens of all types came out, there was initially talk of the "organic" compounds in them reducing their lifepan. Has this happened?
OLEDs do get dimmer the longer they are on. They have improved it quite a bit since they first came out, but it is still an issue. It is similar to CRTs (and Plasma, IIRC) having an image burned on the the screen if they were left on one image too long. Most computer and TV systems these days use "screen saver" methodologies to prevent one image from being in the same place for too long. This should extend the usable life of the OLED systems.

An organic compound is any compound that includes carbon atoms. What is the half life of anthracite ? How about crude oil ? Carbon dioxide ? Redwood ? DNA ?
My question was based on first reports on the new product. Dyes are also carbon based and fade. So far, nobody has reported any experiences with these screens to confirm or deny the early claims.
FYI, even "tradition" LEDs get dimmer the longer they are powered on, but it is much slower. Something in the order of 10% after 1000-5000 hours (and it depends on how bright the LEDs are being operated, because they are pulse width modulated).
I don't remember what OLEDs were initially, and don't know what they are claiming that they have improved it to now.
I guess my point is, for those of us with limited means who do not buy a new camera every three years, how this compares with an old-fashioned DSLR with mirror, etc. I favor EVFs over back screens and would be unhappy if the EVF in my $1,500 camera body began to fail after a few years. As they have been on the market for some time now, I was wondering if anyone has experienced such a failure in their own gear.
Radiojohn: You probably wouldn’t notice a small decrease in brightness over time.

I agree. Your viewfinder probably isn't on for hours at a time like a TV or computer is.

You forgot diamonds.
OMFG ... with extra cheeze.
Thank you. How could I ?!?
Nice catch.
Not sure diamonds are a compound.
Arent they pure crystaline carbon ?
Either way, they have no "half life" measure, being essentially eternal.

Your steak is also an organic compound and so are you😜

By the time the "half life" is reached a new technology will be out to leapfrog OLED by a lot. Today's electronics will not last forever especially for LCD screen technology which fades and also pixels die off gradually...my six year old laptop just recently exhibited a dead pixel - I thought at first it was dirt on the screen but one of my pixels died!

An organic compound has both carbon AND hydrogen. Take it from the chemical engineer

Sincerest condolences. I saw some itty bitty little coffins on Amazon. With free shipping too !
