* The displays are sourced either as surplus or have been harvested from old phones. You can't be certain what you'll get, but whatever you get will probably not be pristine. | * The displays are sourced either as surplus or have been harvested from old phones.

* The main electrical contact between the display and the PCB is through a compressible foam material that was once pretty cool s***. The main issue this presents is that small shifts in pressure on the display housing seem to muck up the connections --- at least they did on my sample. The contrast control in particular seems to be sensitive to housing pressure. Nokia obviously figured out how to work with this interface, but board suppliers might be missing some important know how here. | * The main electrical contact between the display and the PCB is through a compressible foam material that was once pretty cool s***.
