Skip to 10:40 if you just want to see how they were made.
Contents:
0:00 Intro
1:29 First OLED: Tang and van Slyke
2:56 Polymer LEDs
4:25 Principle of the AlQ3 OLED
10:40 Let's make some OLEDs!
11:00 3D-printer photolithography
13:30 Physical Vapor Deposition (PVD)
15:52 Device operation
16:57 Black spot formation/degradation
18:50 Hermetic encapsulation

Video on the inventors of the OLED:

The original paper by Tang and van Slyke can be downloaded for $35 from:
https://aip.scitation.org/doi/pdf/10.1063/1.98799.
I did not do this, so I hope my memory served me well...

Did I forget anyone / objections? Please let me know and I'll set it straight.
ITO substrates can be bought from many different suppliers on Ebay.com, with widely varying prices. I bought mine (5 pieces) from seller "yaolihong2013" (no affiliation) because the same shop also sells Ytterbium.
The AlQ3 and TPD were both bought from TCI-chemicals (no affiliation).
The 3D-printer used for the photoresist exposures was a Phrozen Sonic Mini 4K. Avoid the new update (1.9) of the Chitubox-software supplied with this printer because it does not work properly. Version 1.8 or earlier does works correctly.
Photoresist used : AZ 4533 supplied by Microchemicals (no affiliation)
