These are usually some kind of LCD base. In an unpowered state the liquid crystals are chaotic, scattering light into all direction, creating an opaque layer. With voltage applied the crystals align (along the elctric field I guess?) and will leave substantially more unscattered light through both directions.
Around .3 to .6 watts per square foot, comparable to an LED lightbulb which uses 10watts. A 1 story house with ~200 square feet of windows would be ~60 to ~120 watts or the equivalent of 6 to 12 light bulbs. If you connected the windows to a switch, each rooms windows would take less electricity than the light bulbs.
Probably not, but I guess it could act as a built-in shade screen...thing. To keep the sun out while it's parked. Do people still use those? I feel like they were pretty popular 20+ years ago.
Still popular, but I think the biggest issue is that they take up so much space. I would love one that rolls up like a projector and is attached to the ceiling of the car. Just pull it down whenever you get out, rather than needing to keep it in the backseat or trunk or whatever.
I just did my first install of an office with these privacy shades. The first installer to install this film did a shit job and flecks of dust were everywhere. These specs show up 100x their size. We turned off the hvac, washed everything around it including the walls and carpet, and took our time and it went well. Our cost for 2 office window walls about 7 feet tall was $1500. But doing it twice cost $3000 and looking bad to the client.
Is it a polyethylene type material like window tinting is? If so I can totally understand the ā100x magnifiedā effect. Canāt tell you how many times Iāve been asked to put something like that on office windows while building construction was still taking place, and had to explain to a number of people that āwe cannot make this look the way you want it if thereās dust everywhereā.

I want to see this in a way it blacks out the view entirely.

First the Bobiverse predicts Trump and the total downfall of America into a theocratic hell scape, and now it predicts blinds "printed" on the glass.

I would love a black version of this as blackout blinds for my bedroom.

i thought it's a quantum state thing. when someone tries to look through the window from outside, it goes opaque

A couple more years and you will be able to watch tv on your windows shades
Lynkfox
But honey, we need to get the 4th wall screen so I can enjoy my shows.

You can use a projector on these, works pretty well.

But can you play doom on it
JaimeLannistersRightHand
I'm like 89% sure it can run doom

Is it not see-through BOTH ways?
Cornflakes91
what?
woodworkerf
See through, But both ways. Up and Down.
spitfires2000
I meant opaque. 'Not see-through' = opaque. Not the best way to describe it...
RatOnnaStick
I think when it is set to opaque, then itās opaque both ways.
pineapplecatastrophe
Not everything needs to be electronic idk. Blinds work fine and donāt cost copper
MentalUproar
these appear to be feline and child resistant. they win
Fentex
I'd quite like those, nice to have privacy at the flip of a switch from my chair and blinds with motors aren't as good.
JBloodthorn
Blinds with horizontal slats work fine. The ones with vertical slats fucking suck.
AsheLake
True!
SpartaWolf117
it's a good thing the default state is opaque
TheBlueMuppet
True, but it means that your windows now consume electricity to be transparent.

Start worrying about power outages

Depends on the application if default being opaque is preferable.

Shower doors, yes... windshields, no

I don't think this technology on windshields will be a best seller, but why not

You charged the client for a mistake done by the subcontractor or your employee?
imgary
Our company took the hit.
Neywiny
Ah. I was expecting that but thought otherwise from the way it was worded. So the client just didn't like the extra time needed?
NickRivieraMD
The wording was clear, I think maybe both of us just thought the cost (to the installer) was unexpectedly high.
creamcheezus
Except the grammar of the last sentence.
