The way that I figure it, is that whatever window you want to shade, you will have to totally replace it with a new one and it will be somewhat heavier than the original window. So if you guys are willin to give up some weight for the rin tin tinting then I guess I should get it patented or sumfin.
My project car that Im building will be equipt with these windows (car wont be finished for a loooong time) and if my buddies and I can figure it out, it will also have colour changing paint (not that rainbow or pearl stuff, but actually colour changing paint). We've come up with a couple ideas but the best for that so far has been that paint that changes colour with heat... I dunno... I got a few years before I need to worry aboot paintin my project car tho.
Anywhoo, back to the window thing, there are some companies that do from clear to black windows for homes as well as for shower doors, and theres a couple other but I forget.
The way I have it designed it will be a custom job for each car because new windows would have to be made up (which means $$$), there is always the option of puttin the LCD screen on the inside of the window for a show or something, but any good blow to the screen and its poooooched.

It'll be hard to patent, because it's already been done. you might be able to patent the application to moblie glass.
What we're talking about is twisted nematic liquid crystal displays. a regular liquid crystal display would only have on and off characteristics. Using multiple directions for liquid crystal to travel on would cause different levels of tint.
Here is the steps that would be needed to do it.
1. Cut glass - coated with a thin layer of conductor
2. Clean glass
3. Coat glass w/ PI - PI is a polymer for which the liquid crystals will align themselves along.
4. Bake the glass. PI becomes solid after heating
5. Prep the PI - put groves in the PI for the Liquid Crystals to align themselves in.
6. install glass fiber spacers - prevents the two conduction surfaces to the glass to touch.
7. Sandwich the glass - leaving .5cm overlap for leads to be connected to the conducting surface so that an electric field could be induced. epoxy 3 sides, leave one open to full with liquid crystals.
8.Fill the glass w/ liquid crystal - kinda hard to explain
9.Completion - mount polarizers on both sides of the glass and enjoy!
you all think I'm pretty smart now huh? it's a summary of this website

an engineering 100 project at Brown University. it's only the specs though. no word anywhere on the rest of the project. if anyone goes there, go hunt down some info damnit!!!

I call shenanigans on your whole post. unless you're a high level engineering student or higher, AND work in a field regarding this issue, AND have access to everything needed to do this, you wouldn't know where to start.
BTW I'd estimate that this is a $20k job in itself.

No one said that it would be cheap, but $20k? Your off your rocker!

well if you're going to do it all yourself and you have equip. then it wouldn't be 20k.. but it's such a specialized job, that if you don't have the eqip, and are paying someone else to do it, then I'd say 20k is fair.
I'm still hesitant to believe you. It's hard to believe someone with this knowledge wouldn't use the proper form of your [should be you're of your rocker] and post something like:
"The way that I figure it, is that whatever window you want to shade, you will have to totally replace it with a new one"
Like you were guessing at the whole thing.
But if it's true, Good luck man.

Thats fine, you can call shenanigans if you wish, your opinion. But to let you know, my father is a mechanical engineer, both my brother and I are mechanical engineering students, one of my friends is an electircal engineering student and another is in some computer science program. And yes, I do have access to the materials that are needed to make the windows w/ the tint through contacts of my own and my fathers.

they only deal to company's manufacturing products that use led's/lcd's and not the public, so my *** is really chapped cause i threw away their catalog
cause i doubt i'll be able to get ahold of another one. i'm going crazy trying to remember thier name... i'll search for them and see what i can do.Nick

Second, I am aware that my spelling and grammar suck de ballz and I dont try and hide it, so please refrain from correcting me on it, thanks.
Third, yes, "the way that I figure it,...", I have yet to do a prototype like I said earlier, so I dont have any physical evidence... yet. I say what I said aboot having to get a new window because of two reasons... 1) Why would you want to use the old window? It more than likely has some lil chips in it and such, but that might not matter to some peoples. 2) Like you said in your post aboot brown university, you will need to sandwich them inbetween two pieces of glass (or did you not read your own post?), which therefore means that your window is going to be that much thicker. Getting a new window would mean that you would be able to get 2 thinner pieces, have the LCD inbetween and it wouldnt be as thick as it would if you used the original window.
Forth, I really dont give a rats a** whether or not you believe me because frankly guy, Im the one whos gonna have the tinting windows in my car regardless of you think. Besides, what exactly do YOU do that would make you even more knowledgable in designing such as thing? Unless of course you have already designed one and built it, I do believe we are in the same boat.
NO SOUP FOR YOU!!

I'm just saying alot of the info you posted is pretty obvious. Of course you would have to replace the glass. and you wouldn't put LCD between the glass, you'd put LC (liquid crystal) between the glass CREATING an LCD. The terminology you use is not very precise and you've been vague about the process of creating one.
Like I said, if you're doing it great. but I hate it when people pretend to be doing something/have something to look cool. I've been researching this Idea for about 6 months now because it's peaked my intrest. But like I stated before, I wouldn't be able to do it myself.

Do your prototype in steps.
Break down your design into block diagrams.
1. electrical design and protype
2. electro-chemical design and prototype on glass surface (dosen't have to be a car window)
3. Integrate both 1 and 2 (get the glass to tint at will)
4. Once 3 is complete incorporate unto a feasable window size for the auto.
5. Patent it and become rich.
word to the wise DO NOT MAKE IT INTO A SCHOOL PROJECT. If it is funded by the school then the design is theirs.

Here is a website with someone talking about it (there's even a picture of an RX-7...go figgure).
http://www.bridgeport.edu/cse/projec...cheikh/E1.html
Also, to that guy who wanted to patent it...you're WAY too late. Even if you patent the application for automobile production you have to pay to use the process of making the adjustable tint. It was patented in 1991 by Ronald Elsenbaumer. The patent is titled something like 'Adjustable Tint with Electrochromic Conductive Polymer' or something like that. I don't have the patent number with me.
And finally here is an ABC news article about the matter. Some company produces these for home/office use.
