hey guys,

Anyone know anything about electronic window tints? Always wanted to do this to my car but don’t know how much $$ and time I’m looking at, anyone have any experience?

Thanks

 
Its funny you bring this up because all of them I've seen in jets require an emergency power supply on the cabin door/e-exit windows. The thought is if you crash and lose all power you still need to be able to see through the door/e-exit to see if it safe to open it. That's right, they are dark without power. Power makes them clear. At least the ones I know of.
 
I'm curious how they work. Can someone explain in laymen's terms?

Does it work that way on all planes? I've flown on a 787 twice. The cabin crew can control all the windows and they darkened them after take-off on both flights. When darkened, they block GPS signals, suggesting they have some current. See also: https://www.aerodefensetech.com/component/content/article/adt/features/articles/27502
 
Do they have any films that remain see thru, but just get darker/lighter? Seems I've only seen where it goes from clear to opaque and back. Which isn't quite as useful in a car as would be the ability to dial 15% tint in middle of the day, and put it back to 50% at night.

On my vehicles I've found 20% to be good for me during the day, and acceptable at night, but would prefer a little lighter tint at night... And some days a little darker tint during the day.

These are similar to the liquid crystal in the mode they operate. You place this liquid between two glass plates with a couple of electrical terminals in between / at each end. These liquids have cells that when at rest, no voltage applied, take a certain position, think of it as they lay down and they can be opaque. When a voltage is applied the cells stand up, or separate, you can see through, in the simplest mode of operation.
 
Sounds like an accident waiting to happen to me.

This is basically how they work. I had them installed as floor-to-ceiling office partions in my company office in the Persian Gulf when I lived there last decade. It's double panes of glass with an LCD film sandwiched in between them. Applying a current switches them from opaque to transparent. The ones I purchased were made in France.

In the chronically dusty environment of the Gulf they were easier to keep clean compared to blinds or drapes.
