The unit came with an LCD but I don't know how to use it with the Teensy so I'll just leave the space open (covered with acryl) and have status LEDs.
Couldn't you fit it with an arduino to drive LCD, that should work?

Teensy and arduino are the same thing when when it comes down to it. If you're for whatever reason unable to achieve something with one you're bound to run into the same problems with the other.

I don't know much about teensy but I know you can do basic LCD controll with arduino.

I don't have the specs for the panel. Or don't I need that?

Depends, afair there are a few "standards" but with some googling and tweaking you can get most LCDs to work.

OT: does that include scavenged ones? (like from printers and photocameras)

Yeah, I've done that a couple of times.

OT: Nice! What did you use for controllers? Teensy? *I take it you used the display only, no chips from the boards*

I used an Arduino but any Atmel chip will do.
The necessary chips are usually on a small PCB that makes up the back of the display.

OT: Ah, feared that. Thing is, most displays I come across are attached to a fried board, or have their specific chips on the general pcb (miniscule smd style, with all the useless stuff). Oh well, cheers anyhow- I'll keep you in mind just in case

Are you sure? Can you post some pics? I have _never_ seen a display like that.

ffffuu.. went on a spree to prepend all these with OffTopic, only to realise that they're not.
