This is significant. Current OLEDs at full luminance burn in within 100 hours. The problem is mitigated somewhat by the variety of details displayed during typical TV programming, but if you use an OLED TV as a daily driver computer monitor or with a gaming system to play the same games for hours you will notice burn-in quickly.

I have an OLED TV and after thousands of hours of use, sometimes hundreds on a single game, there is no burn-in. However, I do not set the TV to full brightness.

Edit: I suspect an OLED digital sign WOULD burn in though as I imagine that content is much more static and displayed many more hours per day. I just wanted to make the point that I do not fear OLED for common consumer use cases.

Anecdotal but I had burn in on my LG B7 within a year or less of usage. Chrome and windows start menu button in the taskbar.
