Hi Vintagesynth community,
I was inspired by the following topic:
viewtopic.php?f=1&t=81070&p=759270
I would like to upgrade the 16 x 2 LCD screen to OLED and found out from LLamamusic.com that, the original part is called „DM1620-5BL7” (this is also used for D-110, U-110 and GR-50).
I cannot find any information about the original DM1620-5BL7, but I found the following when I search for DM1620:

Dimension on DM1620:
Outline: 85(W) x 32.6 (H) x 10 (T)
Min. viewing area: 60.5 (W) x 15.5 (H)
I found the following page with overviews of OLED from Winstar and they have 9 different variations in format 16 x 2:

I cannot find the model, which would replace the above-mentioned DM16020 size-wise.
Questions:
There are three concerns in this process:
1. Dimension wise (which model would fit?)
2. Which interface / BUS / protocol is Roland S-330 using? (6800, 8080 or SPI)
3. The Wiring / Pin mapping.
