Hello, I have a Leica Disto that has a bad screen I'm looking to replace but I can't seem to find it anywhere and I don't know what number on the display I should use to find it with can anyone help me find it?

It's a 10 pin white LED backlit display. I think it monochrome but not completely sure.

 

It's possible the part is OEM and cannot be easily swapped out. Sad but true.
Have you tried searching for parts that have the same specs, the same pixel count and dimensions? You might find some options that way.
