Welcome to the community!
Nothing has been announced or officially talked about, so there’s really nothing to provide other than speculation at this time.
Heres some of that baseless speculation, lol. Considering that the 16" Framework laptop isn’t even out yet, I think an OLED option isn’t likely to be available any time soon, even if they do plan to offer one eventually.
I see no reason why Framework couldn’t source a display as good as what Apple puts in their MacBook pros (in fact, I’d say the display IS as good as what Apple use in the Air). Unfortunately, everything is a compromise. They have to balance cost, performance, battery life, customer preference, etc. I only mention customer preference because they actually did surveys and found that the majority of respondents preferred a matte display. Many people prefer glossy displays, but unfortunately, it’s not likely feasible for them to offer multiple options at this time. So they went with the more popular option. I remember when the Framework 13 first came out a couple years ago and only had a glossy display option. The forums were filled with people asking for a matte display or saying they wouldn’t buy until a matte display was an option. Like I said, no one configuration will work for everyone. Unfortunately, they can’t offer multiple configurations right now.
I don’t know if it was for the Framework 16" or the 13", but someone in the community did find an OLED panel from the same manufacturer that Framework sources their panels from and it’s supposedly the same size and has the same connector. No idea of the cost or if the company would even sell a single panel to an individual, nor can we be positive it would work if someone did get their hands on one. But maybe it will be an option at some point.
For now, I think the 165hz panel they went with is a pretty good compromise. Reasonably high resolution, fairly high refresh rate, and very bright for a standard panel. And probably a lot lower cost compared to the mini-LED panel that Apple puts in their 16" pro.
Personally, I wouldn’t want an OLED panel in a laptop. I know, the burn-in issue isn’t as big of an issue in a laptop with an easily replaceable display, and OLED displays have gotten better about resisting burn-in. But I would never be able to stop thinking about it, lol. But I know they can look fantastic (some would argue, better than the mini-LED display Apple uses, though not nearly as high peak brightness).
