E-ink is Beta-Testing Electronic Window Tint (video)

Tinted windows are great – they give you privacy and limit the amount of sunlight which can penetrate. But they are not so great when lighting is bad.

Luckily for us, E-ink is working on a solution. Mike Cane just pointed me to a demo video where E-ink shows off their Just Tint technology.

That is a cool trick, but I am not sure we’re going to see widespread adoption. For one thing, in most cases curtains and blinds will work just fine while costing a lot less.

The good news, however, is that there is already similar tech in the market. I found tech from a competing company called Smart Tint which can be retrofitted to existing glass, or added during construction. They can design a window tint in any number of colors, and are reportedly already shipping.

Clearly this is an established market, which means that one company or another could license E-ink’s tech, and bring it to market.

Would you use it if you could?

    It is light valve tech that is well understood, cheap to build, and can be built in massive sheets/panels very cheap.
    And a totally transparent version is commercially available in TVs.
    (Where it’s really a stunt but it shows how mature thin and transparent LCD substrate tech is.)

    So the tech exists.
    The market for it? Not so much.
