OLED display for MM/MD/OT(mk1): possible design to replace that LCD

No.
The OLED panels are of the shelf parts that are found to fit (with some margins for plastic holder) the spatial envelope of original.
So: no… Unless of course, you find a red OLED panel that fits in there. You can go research www.panelook.com for that first. Resolution should ideally be also the same.

So far I have only seen white and yellow units that fit. But of course, red film on top should be an option… That will tradeoff brightness here, of course.

Thank you for the quick response!

True, red film makes sense…can you invert the colors on these OLED displays, so the writing is black and the background bright?

To be clear - the product does not exist yet.
But yes, the idea is to implement color inversion via DIP switch (under the OLED panel) exactly like I’ve done for Analog Mk1 screens.

Hey @ zigmars don’t suppose there is any progress on the OLED screen for OT 1? :slight_smile:

Slow progress, little by little is happening.

I got tired and discouraged at some point doing this (or any) project for a while,
so it’s a good thing you remind me here, that there is some interest in this. :slight_smile:

In summer I bought resin 3d printer, for faster iteration and lower (long-term & engineering) costs. I am new to resin printing at home, so that is a rabbit-hole for me in addition to everything else.

Somewhat recently I redesigned the bracket a few times, so the last one(s) finally fit the PCB. In short - nearing the (hopefully final) reasonable (reliably manufacturable, as little post-processing as possible) bracket solution.
And have tested two different 2.7" OLED panels on this one PCB, as it seemed, that any one might at any point just become obsolete & unobtainium.
Broke one OLED, thankfully had other unit of that particular model. Tested both models - one worked flawlessly, the other has some intermittent issue, where sometimes it works, sometimes doesn’t. (Might be an issue with MCU’s & crystal, not the OLED itself.) Have not fully investigated this.

Actually, today I am trying another 3d resin, that might be the best one so far.

Hey, glad to have reinvigorated the work :slight_smile:
If you need any help testing etc happy to help. I do a lot of DIY so could build one too to test
