Thank you very much for the link. However I'm a bit skeptical about the cycle life mentioned on that website, sounds more like product marketing than some result backed by experiments. But that said that is for around 60V AC while we need few DC volts. If it were the case, a PDLC shutter...

Nonw of the companies responded back about inkjet printer compatible transparent conductive ink. One company replied they have silver nanowire that can be used for making an opaque conductive inkjet ink but couldn't provide info how to create such a mixture. Thats all the info I got.

Neither acetone nor paint stripper detach the PDLC and ITO PET layers. Acetone and paint stripper also don't seem to have visible effect on the PET so far. Acetone does remove the glue from the protective layers on both outher sides of the smart film (PET and PDLC layers) so I'm guessing the PET...

To update on this I have cut 3 small peices from a bigger smart film and submerged each in 1) acetone, 2) paint strip solution, 3) 35% HCl Zn. Will check back after few hours see if any affected the bonds. By the way is there any info whether there's some adhesive sticking the PET to the PDLC...

I'm not concerned about voltage drop but rather whether this layout will generate the electric fields with the orientation and angle needed.

By the way the lines are only connected on one side in the diagram, is that fine?

Maybe better to first try to dissolve the glue keeping the PET (and the ITO on it) attached to the PDLC as PET is a bit tricky to dissolve.

I'll have to email each company and ask if their inks work with inkjet printers. Ill post my findings here. Second question is whether the ink will stick to a transparent film such as PET instead of paper. T-Ink and Sunchemicals are the same I think.

I don't mean to be rude but I get this a lot. Googling "scientific evidence for santa claus" returns 500 000 hits, doesn't mean any of the results is usable. That's just how google works, even when it finds real useful pages it's just the first one-two pages of its list tops. I went through 2...

ITO is on the inner surface of the PET films. I could dissolve it, but I don't see how you can dissolve just one of the ITOs. And I'm not sure if I follow you, you mean to dissolve just the ITOs of the PET films, then overlay 2 extra ITO PET films on those pet films? Each PET only has light...

If white light only consists of a single wavelength red, green and blue lights, such as 450nm, 520nm and 635nm? I think that's how LED projectors and 3LCD and 3DLP projectors work, the former only generate those wavelengths to begin with, the latter filter out green, blue and red wavelengths...

Very interesting! A single-chip XGA resolution (1024x768) 2000 lumen video projector can be bought for less than $200, then the color wheel taken out as well as the UV filter. This makes a grayscale projector bright enough for the projection to feel warm to the hand and can be focused to small...

More info please on tranfering the image optically. I have a bright video projector (5000 lumen) and a visible light (445 nm, 520nm, 635nm ) laser beam scanner but not sure what needs to be done here. I saw that page earlier today but don't see how you can cut a mask from a kapton tape with sub...

Need two transparent conductors in an arrangment like this on a transparent plastic film. Such as ITO on PET. But it doesn't have to be ITO necessarily. There are going to be much more fingers and size of the lanes and their gaps are going to be sub milimeter, so hand drawing is out of the...

Any suggestions how to remove the original ITO pet film to be replaced with a custom etched one with least possible damage to the PDLC itself? PDLC layer is adhered to ITO PET films from both sides so there's a risk of breaking the PDLC film and leaving chunks of it on the unused PET film which...
