back to article LG unfurls flexible SEE-THROUGH 18-inch display

Not content with making the world’s biggest bendy OLED TV, LG has thrown a different curve entirely with its roll-up OLED display. The 18-inch flexible panel has a 1280 x 810 resolution and uses a film of high-performance plastic called polyimide to give it its flexibility. LG flexible display Outsmarting the bendy smartphone …

Patent This!

That transparent display, set spinning at a fairly high speed on a turntable, could make an effective real-3D display technology.

(Although you might get a whack on the nose if you lean in too far.)

Re: Patent This!

That's a nice idea but the screen would need a ridiculously high refresh/update speed.

Re: Patent This!

"Volumetric Displays" where a screen rotates (often illuminated by laser) already exist: I've seen one used for molecular model display. And I'm pretty sure I read about the concept last century.

[edit] Ah, or as said by above, it's already available. :) [/edit]

It's been done. One exists already.

An old school option is a spinning disk (or any surface) with a projector (or laser) pojecting your frames/pixels onto it. :)

Re: Patent This!

How about instead of one spinning screen, have three (or more) transparent screens in front of each other with gaps between them, have the background on the rear screen the foreground on the front screen and everything else on the middle screen. No idea how to prepare a suitable image, I suspect they'd need some of those computer thingies to work out what's what.

Not full blown 3D of course but would give an impression of depth and perspective without having to spin something up, mind you to make this work I think the screens need to be more transparent than these early iterations.

What are the odds...

Besides flexbility, transparency is set to be a major selling point

That if this type of device were to take off then they'd spend most of their time pinned up against a black background and shown the same sort of crap that current devices do?

I can imagine pretty eye-catching billboards set against a great horizon. If you could position one so that Manhattan was visible through it, and then have people apparently parkouring all over the skyscrapers? Of course, you'd have to keep changing the action or we'd get bored.

Like current displays can do if we just add a camera to them? Transparent displays are usually used in areas like transportation and security... not for TV viewing...

Unless... [goes off to patent a 100% transparent display, transparent 100% of the time and invisible to consumers]

Would prefer a folded display, that way it can slip into a laptop case and be unfolded when required.

Fit inside double glazing windows

Just use larger sizes and fit inside double glazing windows (with a Pi or similar).

Finally we can see what we would like to see though our windows.

Downside - the image would also be visible to those outside which might restrict viewing subjects a little.

Also - they would probably be an internet of things item so it may be possible / fun to hack other peoples similar windows.

Not necessarily. All sorts of magic can be worked with polarising filters and the like. Arrange things right and the people outside would only see a white screen.

"Downside - the image would also be visible to those outside which might restrict viewing subjects a little."

Not to much of a problem. As I walk around where I live there are houses where the TVs are so enormously mahoosive, I don't know if the inhabitants are breaching some kind of pubic broadcast law. I'm sure the sheep from across the valley are keeping up with events in Eastenders.

All hail LG, king of pointless gimmicks

Unfortunately, for all the engineering prowess it probably requires to create a bendable, transparent display, I'd bet my lunch's money LG will have no idea of what to do with it – just like with the 3D display smartphones. Remember them? Thought so.

Best case scenario, this will eventually make its big-time début in a "revolutionary" iThing.

Re: All hail LG, king of pointless gimmicks

Uses? Signage and advertising. This isn't a domestic technology.

One application springs to mind immediately: in Continental Europe, a lot of advertising posters are attached to large-diameter pillars at street-corners (http://en.wikipedia.org/wiki/Advertising_column).

Think of the demand for a digital advertising screen that could wrap around these.

This will be convenient when we can have a useful size of screen rolled up in a pocket. I like to imagine that phones will be around the size of a pen and just roll out as needed.

Rollable touchscreen

I've been waiting a while for a roll-up touchscreen that can connect wirelessly to my phone. Leave the phone in my pocket and I can easily unroll the screen to do a bit of work (tablet style) then roll it back into its protective tube when I'm done. Nice.

See thru Haynes Manual Overlay

Wow, this has been done in the game Hydrophobia where the main character unfurls from a stick a tablet sized see thru screen. She lines it up with some spaceship engine and gets working schematics that allow her to more quickly determine the parts that need repairing.

If this comes out as a finished product, would it kill the nascent Augmented Reality tech companies using smart phones over your eyes? I suspect hands free would only survive in specific niches.

The Google Glass form factor is far better for something you're working on because it leaves both hands free to actually do the work. A pen with a screen you could unroll would make a pretty good phone; but it might be better to project your screen in the long-term, as an unrollable screen would be quite the weak point.

Patent troll in the making

What puzzles me, and perhaps this is what the transparency technologists are already doing - is surely to get a transparent display, you just need a vanilla calculator-like monochrome LCD display behind your standard colour display?

The monochrome one, if it has enough DPI, effectively creates a transparency layer that the colour layer renders over?

I dunno if this would work, but that would be how I'd begin exploring the area. I highly doubt this is a novel idea, but if it is - I claim all patent rights! *runs for the hills*

the real benefit is the robustness

My kids both have ipads, both of which have suffered various scrapes and dings. If this screen is as flexible and hopefully power friendly as indicated (if using e-ink type technology) then it would be a must have accessory for any phone. No need to have a phone and an ipad, just one device and either a small screen built in, or a huge screen unfurled at a moments notice.

There's definitely a market here, it just depends how power hungry it is, and how whether they can make it small enough to roll into something you can slip into your pocket.

Why not variable 1024 x 1520 to 2800 x 1520? for 19"? (Portrait, to 4:3 to Widescreen)

My 12 year old 4:3 15" screen is 1600 x 1200. Why aim for such low resolution?
