Chameleon Liquid Could Replace LCDs

InvisblePinkUnicorn writes "NewScientist reports on a color-changing liquid that could cheaply replace the color components of standard LCDs. According to researchers at UC Riverside, the liquid 'contains tiny iron oxide particles coated with plastic. It is cheap and easy to make, and could also be used in flexible, rewritable, electronic paper.' From the article: 'The opposing forces of electrostatic repulsion [in the plastic] and magnetic attraction [in the iron oxide] result in the particles arranging themselves into an ordered structure, known as a colloidal "photonic crystal". The colloidal crystal reflects light because the spacing between neighboring particles in the structure is equivalent to the wavelength of light. Also, tuning the spacing slightly alters the exact wavelength, or colour, of light that is reflected. This can easily be done by varying the strength of the magnetic field applied to the crystal.'"

And as usual..

..with anything new, cheaper, better than what's currently being flogged by the megacorps in the industry, this thing will not show up anywhere on the market until every single cent in old TFT tech has been squeezed out of the customers.

Seen better

So you could change the color with a magnet? Big whoop, other color technologies like this are much more feasible for widespread use. The penatrative qualities in that color is just remarkable.

I believe it's you who needs to open your eyes.

From the third line in the summary:

It is cheap and easy to make, and could also be used in flexible, rewritable, electronic paper.

Again with the retarded shit spewing from your diarrhea-filled mouth. Don't you ever get tired of butting in and being wrong?

He didn't say he didn't get the joke...

It just wasn't funny.
