1. ITO Coated substrate (flexible sheet coated with a conducting material)

2. Phosphor ink (pink ink)

3. Dialectic (white ink)

4. Conductor (silver ink, could be other conductive materials)

5. Masking tape (isolates the bottom conductor ITO from the top conductor)

Simply connect an alligator clip from the ITO coat to a pin in the EL power supply and the other alligator clip from the top Conductor layer to another pin of the EL power supply. You should hear a high pitch sound if the two alligator clip are connected correctly.
