LG Phillips Patents Oil and Water Display 90

jordanhh writes "Tech.co.uk reports that LG Phillips has filed a patent for a new type of thin, flexible display. 'The pixels are made from tiny plastic cells filled with minute amounts of oil and water. The oil floats on the surface of the water and shrouds the colored surface underneath it. When electricity is applied across the cell, the oil moves aside, changing the color of the pixel.'"

      No, that's what it actually says. The headline doesn't have boldface, though.
      At least it isn't "British Left Waffles on Falklands."

          Needs a little introduction, but here goes - there is a fairly low-end football team in Scotland called Inverness Caledonian Thistle, and a much much better team called Glasgow Celtic. Now as it happens, Inverness Caley were drawn against Celtic for a particular match, and things were, to be honest, looking like a bit of a foregone conclusion.

          A chap I know is one of the sports writers for the daily red-top rag, The Daily Record. Like most tabloids, about a quarter of it is sports pages, and what they do to get the issue out quickly is have two whole back pages set up - one talking about Celtic's win, one talking about Inverness Caley's win (should it happen). So they're sitting in the office the night before the match, writing up headlines to use for the next day. One of my mate's colleagues says "Oh, well it's never ever going to happen, but - 'Super Caley Go Ballistic, Celtic Are Atrocious'?"

          Celtic basically needn't have turned up. Inverness Caledonian beat them 4-1, and the headline went out.

    The "E-paper" and "E-ink" crowd have been touting "cheap, flexible displays" for about fifteen years now. But all they ever seem to deliver are expensive, rigid displays inferior to other technologies.

    Electrostatic oil displacement has been used before, most notably in the Eidophor [spgv.com] projection TV system. This is a technology first demonstrated in 1939, yet in use through 1993. Big, heavy, expensive, and complicated, but could project TV pictures brighter than film. The image medium was an oil film written by an electron beam, used as a reflector for a lamp.

    The basic idea is simple, but making it work required rotating smoothed oil film past the projection station, so there were big moving parts. All this had to happen in vacuum, but it wasn't a sealed unit, because the cathode had to be changed every 200 hours or so. So it needed high-vacuum pumps, vacuum locks, hours of startup, and a skilled operator.

    • making it work required rotating smoothed oil film past the projection station...
      Made me wonder-can this new display be vertical? Wouldn't the oil separate to the top, exposing water on the bottom (fine for horizontal use)?

        It's a pixel-sized cell thing; each cell is sealed. At that scale, surface tension beats gravity, so orientation may not matter much.

        • yeah, right after I replied, I thought of surface tension at that tiny size, being dominant!
          Still, it might be fun to shake it really hard & see what happens :)

              That's been tried. The Iconorama [ed-thelen.org] was a 1950s effort by the USAF to build a large-screen display. This was a computer-controlled Etch-a-Sketch like setup arranged as a projector. As with an Etch-A-Sketch, there was no selective erasing; when the image (which was mostly the tracks of attacking aircraft) became cluttered, the entire image was cleared and replaced with a newly drawn one. The previous big-screen attack plotting technology was an edge-

    good as a toy if you're rich and wanna be like... "LOOK WHAT I GOT!!!"

    however they say they wanna use it for marketing purposes such as wrapping it around street furniture [tech.co.uk]...

    HOWEVER it also says in this part [tech.co.uk] that it needs to be viewed from 180 (straight on)... which would make it invisible to passing vehicles almost always and i'd imagine since it's "not as bright as a standard LCD" that the sun light will just wash it out anways...

      But it looks light weight, which might prove useful. I think it's funny the first thing they think about is the Minority Report-like ad displays, but there are many more uses for this. As an artist, it would be cool to send my portfolio in one of these rather than a CD or something where someone has to make extra steps to load it into their computer, they just unroll this and the display starts. This being if they could get the price down enough for it to be treated in this kind of casual fashion. If it'
