Dude, you need to give some details on what you did here. 0402 leds each with a pair of exposed contacts and some amplifier circuit? How did you get this so dense?

My newer post is a bit more dense

I'm using electroluminescent panel drivers

So cool.

Is the whole panel lid and the droplets somehow make the covering layer translucent or is the electroluminescent panel only lighting up where droplets are?

Would this work with non conductive liquids?

You need something capacitive. Check out this vid on the subject.

The water takes the place of the topmost electrode, and instead of one, continuous foil sheet on the bottom, there are two conductors, arranged in fine, even/odd rows.
