Waterproof 4x20 LCD Case

Electrodude

I need a waterproof enclosure for a 4x20 character LCD or VFD mounted in an industrial-type aluminum control panel, so that it's visible in sunlight and at night from several feet away. I have a Parallax 27979 LCD, and it's bright enough, but somewhat larger characters would be nice. If I use some other display, it still has to have a 3.3V-compatible or RS-232 serial interface to talk to a Propeller, which is mounted elsewhere and already has a waterproof enclosure I'm happy with.

The LCD enclosure needs to be waterproof from all sides, and it has to look professional. It shouldn't have buttons, but a pre-made enclosure that has small, inconspicuous buttons but is otherwise what I want would be OK. Flush with the panel would be best, but isn't necessary. I've looked all over the Internet, and haven't really found anything that's what I want. I made a 3D printed case with an acrylic cover, but I'm not really happy with it because it looks 3D-printed.

Does anyone have any suggestions for where to buy or how to easily make a suitable LCD enclosure?

Thanks,
Electrodude

You could take a look at PolyCase to see if they have anything that fits your needs. They have both metal and plastic waterproof enclosures. I've used their cases before and they are of good quality and reasonably quick deliveries.

Lots of LCDs from an early Parallax developer.
Also faceplates.

Also there are a lot of tech notes, including,

Waterproof and aluminum are another matter. One thing I've done one-off is to CNC the bezel opening in a Hammond 1590 series black finished aluminum enclosure, then flush-mount a frameless Newhaven chip-on-glass display up against the inner surface, then fill the enclosure with silicone potting compound.
