Coming Soon(ish) From LG: Transparent, Rollup Display

Unknown Lamer posted about 4 months ago | from the animated-wall-paper dept.

Displays 64

jfruh (300774) writes Korean electronics manufacturer LG has shown off experimental, see-through, roll-up displays, paper thin and flexible and capable of letting through about 30% of the light that strikes it. The company is eager to sell the concept and promises it'll be arriving soon, though they've shown of similar (though less capable) technology over the past few years and have yet to bring any products to market.

Almost a million megapixels! (3, Funny)

by (1706743) (1706744) | about 4 months ago | (#47452249)

From TFA, so it must be true:

The rollable display sports a 1200x810 resolution with nearly 1 million megapixels.

I just wish my bank did that sort of math...

Re:Almost a million megapixels! (0)

Anonymous Coward | about 4 months ago | (#47452441)

True, reporters can't do maths. They can't even speel rite.

Since they can be controlled independantly, if you count the individual OLEDs as pixels then you get 2,916,000 pixels. So it's almost a 3 megapixel display.

The article has another funny error:

Wouldn't a straight plank of wood have the maximum curvature radius? I think they should aim for the minimum instead.

Greyfox (87712) | about 4 months ago | (#47452265)

Scuttlebutt's there's a transparent roll-up display coming soon since, what? Around 2004? Maybe even a bit earlier. OLEDs were supposed to deliver them back in the day. And yet here we are 10 years later, still no transparent roll-up display. Doesn't seem like this should be as hard as a flying car, and yet they both share the same status. I'm sure this one will be different though...

Promises... (1)

default luser (529332) | about 4 months ago | (#47457491)

Also, there's the unavoidable problem you have with display clarity. Right now screens are on a flat substrate, and so each pixel is aligned with the next one, which reproduces an image accurately. But what happens when you have an unrolled display sitting on your desk, or held in your hand? It will inevitably be have varying levels of curve along it's length and possibly more complex crumples, resulting in poor image accuracy. Fixing that will require some clever sensors embedded in the display along with some expensive signal processing, and that fix will STILL cost you resolution.

Then when you consider that LG's current flexible displays have poor color rendition and contrast, along with piss-poor resolution [arstechnica.com] , you realize how much of a lost cause this is. I cannot see myself giving up the best qualities of modern displays so that they break a little less often, and can fit in a smaller pocket.

So I can see what's behind the display? As if we don't have enough issues with sunlight reflecting from display surfaces, now we're going to let the light coming from *behind* the display further reduce its readability?

Re:Can someone explain... (1)

Anonymous Coward | about 4 months ago | (#47452661)

Can someone explain the appeal of a transparent display?

You can see through it. That's very helpful for augmented reality. Being flexible makes it easier to attach to things and being transparent means that you only obscure as much of what's underneath (or beyond if the substrate is also transparent) as you absolutely need to.

Re:Can someone explain... (0)

Anonymous Coward | about 4 months ago | (#47452667)

The really nice thing about transparent displays is that they look cool. The useful thing about transparent displays is that they can be trivially backed by an opaque film.

Re:Can someone explain... (1)

Immerman (2627577) | about 4 months ago | (#47453477)

Potentially both - imagine a transparent display with an additional switchable opacity layer integrated into it - essentially making a full RGBA display where opacity can be specified on a per-pixel basis. At the most trivial level you could have opaque application windows floating on a transparent pane that obstructs your view as much or little as necessary, sort of like having a bank of adjustable-sized monitors. Laminate it onto a north-facing picture window with a great view and I'd be sold.

Re:Can someone explain... (1)

drinkypoo (153816) | about 4 months ago | (#47452733)

There's lots of potential uses, although pretty much zero of them are on your desktop.

On the other hand, flexible displays will be useful as soon as we get decent flexible batteries and circuits, just helping us not destroy electronics. Of course, the batteries are only halfway there, and the circuits will be completely throwaway and even more integrated than now. At least some repair is possible today...

Design the spot so the background doesn't bleed through the display and you can have different focal point when you don't want the tv on.

Worse than useless as a HUD. Downright dangerous. A proper HUD is features a collimated display, so you don't have to take focus off your environment to look at it.

Didn't their market research branch let them know that this has no widespread practical use and nobody wants this? What is the motivation to replace my monitor with this? For an ultra-thin cell phone, it has major piercing damage risk issues. I just don't see this taking off. It's like making a smart watch just because you can but conveniently forgetting that nobody wants one.

Re:wait a minute (1)

Anonymous Coward | about 4 months ago | (#47453141)

I think their market research branch must have forgotten to consult you, and may have accidentally focused on companies that have been waiting for this stuff for ages and will give them pots of money for it.

Sunglasses, windows, motorcycle visors, car HUDs, "open plan" office cubicles (though that'd be a mistake, it would be a mistake enough people would make to justify putting it on the market).

fizzer06 (1500649) | about 4 months ago | (#47452907)

I'm thinking the display could roll up inside of an ink pen like a spring loaded window roller shade. Some enterprising genius could also implement sensors to reproduce script written on paper by the pen to the screen. I'm dreaming of a lot of possibilities.

Yeah, normally you'd quote a radius of curvature as an actual unit of length - the radius of the smallest curve the material can take without failing. I'm not sure what "100R" means except something like a translation or transcription error.

I don't understand the appeal of transparent displays. Sure, it looks great in scifi shows and movies, but what happens when you want to do something without people seeing what you're doing? Now, instead of just worrying about shoulder-surfers, you've got the additional problem of people simply reading backwards print.

In college my tech Professor asked when we would expect to abandon paper as a reading device, I said when the resolution is indistinguishable and I can roll it up and put it in my pocket, this was around 1992. He offered the opinion it was only 10 years out - there were reports of flexible lcd's even back then. e-Ink screens made me nervous for a while but I'm still clinging to my dead tree novels for now.

Re:So sell it already. (1)

Sockatume (732728) | about 4 months ago | (#47455389)

This is a good sign. If someone's showing you technology every year and it's gradually getting bigger and better and eventually starts showing up in products (like LG's TVs) then it's a science and engineering problem that's being advanced. If someone's showing you a technology that never existed before and it's suddenly a whole product, it often means it's so premature it's going to fail and better products will climb over its still-warm corpse towards success, or that it's a scam.

That sentence... (0)

Anonymous Coward | about 4 months ago | (#47458023)

LG Display used high molecular substance-based polyimide film as the backplane of the flexible panel instead of conventional plastic to achieve the maximum curvature radius.

As somebody who studies polymers, that sentence is a failure by the author to understand the science, on so many levels...

I don't know where to begin but I should start by pointing out that those polyimides are probably plastics below some temperature. Also spoiler alert, they will have problems making it any thinner, and problems with overheating, and problems if you try to use it in the Antartic (Also possibly Canada). Also the manufacturing techniques will be problematic as well. Normal nano imprint lithography will probably have a very high defect rate due to confinement effects. And if they aren't in the region of problems with confinement yet they will be soon enough.
