LG Phillips Patents Oil and Water Display
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.'"
What? No vinegar?
This guy's the limit!
You patented oil?!

The bible says it's his & occasionally god tells him that he should do it. By the way, we need to stop Karl Rove from getting into that crawl space in the white house right above Bush's bedroom
Am I the only one who read this as LG Phillips Patents Oil and Water Display ?
Moderator hint: a comment is neither "Flamebait" nor "Troll" if it is true.
The patent part anyway. The probably sunk millions into it but no one here thinks they should be able to profit from their innovation, right?
Yeah, man... I saw something like that on the screen over the heads of the Jefferson Airplane back in '67. At least I THINK it was on the screen... oh... WOW!
Thanks - I'll be here all night.
They expect to get excellent blacks (the bane of digital display technologies) by using motor oil from my 1999 Saturn.

This was the big news from Philips/LG last year. Did they score another patent on this or is it the same one?
I never get used to these constant resurrections
That really paints the term "dead pixels" in a new light.
I'm waiting for Hidden Valley's research into a ranch-based display to pan out.
That makes much more sense. The one from tech.co.uk talks about floating, which would make it useless for the applications mentioned.
('street furniture' => 'bus stops') ie. vertical, not horizontal mounting
Build it, and they will come^Hplain.
It's Philips with one "L", by the way.
this is exactly like the light show I saw at a Dead concert once.

Now, cue the slashbots, all of whom will be saying "Haw! Haw! They patented oil and water???!!! So now they are going to sue every city that has oil slicks after a light rain? Patents suck! Information wants to be free! Buy a beowulf cluster of Macs that run Linux that only old people in Korea will use! In Soviet Russia, oil and water patents YOU! Profit! I for one, welcome our new oil and water overlords. Profit!"
I feel like death on a soda cracker.
Will Linux support this?
The game.

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 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.
...something else to drive up the price of oil!
Oil based displays have been in use for years. In fact, there is famous prior art.
How exactly does oil float on the surface of water in a vertically-oriented display? Wouldn't the display have to lie flat like a table top in order for this to work?
so is it that different from this tech? Eink has been around for quite a while now.
You can't handle the truth.
I that think OLEDs is the best solution. I thought that the oil is going too used up in the twenty years; give or take. If the manufacturing of OLED is to hot for the plastic to cure right; then they need to use a technology that cures plastic a cooler temperatures to make OLEDs and this process will make cheaper and better. http://www.riddletechnologies.com/ I believe it or not that this technology can be used for other applications as well.
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...
HOWEVER it also says in this part 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...
cool tech honestly.. but mostly useless I say

Trying to fix or change something only guarantees and perpetuates it's existence
No they don't. They report that LG Philips has done so. How hard is it to at least get the name of the subject company right?
And it's not even right in the headline. Sometimes I despair.
First to name the old SOD.

Looks like Sharp will have to rename their Aquos line!
A slow display, which freezes in sub zero temperatures, must be laid flat on a table, and does not work in zero gravity environments. Brilliant!
And what does that word mean, when translated from the German?
I feel fantastic, and I'm still alive.
So this is the real OLED, an Oleo (oil) Display, or should that be OLEOD?
This comment is well informed but has some important details wrong.
What Philips did sell to PVI is a business that uses E-Ink http://www.eink.com/ technology. E-Ink uses an electrophoretic technology, where tiny capsules contain both black and white particles with opposite electrical charge and fluid. Applying a voltage across the capsules makes them look black, white or grey from the users side. No coloured oil involved.
SiPix http://www.sipix.com/is similar, but uses only one kind of particle and a coloured liquid.
A spin-off from Philips, namely Liquavista http://www.liquavista.com/, developed the oil and water based displays and is currently marketing and mass producing this type of display. This technology is also known as electro-wetting. The principle is that an electric field is used to change the surface tension and thereby change the pixel electrode from hydrophilic (loves water and will be covered in water) to hydrophobic (doesn't like water and will be covered with the oil). The material not covering the pixel electrode is stored in a small reservoir at the side of each pixel.
What is new in the LG-Philips.LCD patent application, is not the oil and water idea, but the application and/or the exact implementation in a flexible display.
Prior Art!

Just what everyone needs: A color Etch-a-Sketch monitor.
That's been tried. The Iconorama 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-lit Plexiglas map with people in on the back side plotting with grease pencils, so the Iconorama was a logical upgrade.
This was a mechanical device. The thing really was etching lines on a projection slide. "Erasure" was accomplished with a slide change to a new blank slide. The Iconorama was usually installed as a pair of units, both for backup and so that slide changes could be accomplished without waiting for a redraw.
I never actually saw one, but a 1970s evaluation of USAF large screen display systems once crossed my desk, and I recall the recommendation on the Iconorama being "Further systems of this type should not be procured."
