How do I connect this scavenged LCD screen to an Arduino Uno? Answered

This morning I dismantled an old Palm Tungsten E that I had laying around.  I was able to extract the LCD screen and want to use it in an Arduino project but I'm not sure what the best way to connect it to a breadboard/Arduino might be.  It appears to have a 40 line bus ribbon (they're small so I might have miscounted).

Start by salvaging the ribbon socket.

I usually do this by cutting the circuit board with my drummal.

The cut circuit board gives you something substantial to solder leads to.

Trace the connections so you know 1 from 40 and so on.

Then if you can get the data sheet for the LCD most have the same connections.

If you Google “Nokia LCD display” there are Arduino projects that tell you the rest.

You may need to adjust the code for the Palm Tungsten E LCD.

First you need to identify the driver chip for it. If it's not built onto the screen you'll need to go back to the palm and track it down. Once you have the chip and can find a data sheet on it you can start looking for the pin out and figuring out a way to either adapt an existing library or create your own to run the screen. Chances are you won't be able to get it working with an arduino.
