It is just a standard 2x16 alphanumeric display with 16-pin connector & backlight on pins 15 & 16. Mine happened to be green. You can buy those anywhere (online).
Top line shows menu/section name (red = Filter), bottom line shows parameters controlled by P1 & P2 (cyan = filter EG & LFO depth), their values are on the right (0-99). Another way of displaying would be to give each parameter its own line.
You can make it a bit nicer with e.g. an add-on board plugged on the Daisy Pod and take the 5V from the pod as well. Or make it all 3V3.
