See #127 above: the problem seems not being the display panel in itself (btw, would love an OLED on my QY100!) but the display control system.
As Eric wrote, I also did some (sloppy) research, and always ended up to that "not completely sure" wall...
Anyway, joining effort could be an idea, so, here's some questions, I can open up my 100 to give some answers this weekend...
- the LCD assembly (going from memory here) is attached to the main board via a small (9 wires?) flat cable. This would be the interface towards a new (OLED?) screen.
- which kind of controller/protocol/signalling happens on that ribbon connector?
PS: as many others here I also have at hand the data sheets for the LCD assy (see at thread top). Can post/store here if someone asks for.
