New Magnetic Display Technology Could Replace LCDs

Researchers at the University of California, Riverside, have created new display technology using a liquid filled with plastic-coated iron oxide particles. The highly charged particles repel one another and arrange themselves in an ordered structure called colloidal photonic crystal. Each of the particles would become a pixel that represents a unique color. The particles in the liquid can then be controlled with a magnet that is placed behind it. Because the microscopic spacing between the particles is equal to the wavelength of light, the surface reflects light. The researchers were able to create a range of colors, and believe this new technology could be used to make large displays much cheaper than current LCDs. It is highly visible outdoors, and could also be used for flexible, rewritable electronic paper.

...we can turn magnets into paper, but we can't make an f'in car run on anything but oil... 🤣 🤣 🤣 🤣
The sad truth is we CAN and HAVE, but Big Oil has too tight a grip on politicians, we'll never see oil go out. Remember all those electric cars that were so ugly? They were forced to be recalled, the govenrment doesn't want them on the road.

And re...
Are you into technology at all? Don't you know that there are cars that don't run on oil? If you speak of Using... not running on oil than your almost right. If your speaking of Gasoline, your completely incorrect.

...whole paragraph made my head hurt.
Yeah, kinda hard to understand stuff. But heck, we probably won't see it in handsets until late 2010, if at all.

It's just in the research phase, and so on.

A few questions

I've noticed they compare it with LCD and attempt to call it an LCD replacement. Well, we already have an LCD replacement. The OLED is the LCD replacement which uses way less energy gives it a brighter picture, which lasts longer, and can even be flexible. In fact, Samsung displayed one of these about 2 months ago at a road show. I think this story should go into more detail and specs. It should give the pros and cons about this tech. It seems to me that a magnet would kill this TV. They fail to mention size, weight, and life. I'm curious as to if this is the last time we hear about it? It seems like OLED finally started showing up in phones in recent years, but the tech has been around for a long time and we still see no TVs with the tech. ...
i'm sure as more info becomes available, we'll get it. perhaps there were no "details and specs" as you request. it's new technology, so we don't know any pros or cons. although the pros seem relatively obvious (easier to see in sunlight, battery l...
