To reuse these in Arduino projects it is useful to have them mounted on a PCB.

After disassembly the LCD's transparent light guide can be trimmed down to the size of the LCD:

I have some spare Diymore Nokia 3310 adapter PCBs that can be modified to accommodate them:

The four LEDs were removed from the top of the Nokia 3310 adapter PCB, and the capacitor on the bottom was replaced with a wire (there is a capacitor mounted on the Nokia 1100 LCD's light guide with the backlight LEDs. So it doesn't need an external capacitor for the LCD voltage booster, and doesn't need the blue LEDs). Then a piece of the reflective white backing from the phone's PCB was applied to the top surface of the PCB to give a reflective surface for the backlights:

The tidiest way to secure the LCD to the adapter PCB was using a modified frame from the original faulty Nokia 3310 display:

Tested with Arduino Pro Mini, 8MHz, 3.3V:
