Sorry for my lack of knowledge on the subject as I'm just a programming student, but wouldn't graphene work well as a backing for such a device. From what I've read, graphene has transparent properties, can conduct electricity if needed, is extremely flexible/bendable, and wouldn't be bothered by heat when making the product in factories. Graphene should probably be ready for 2015 if it's going to take some time anyway. I welcome corrections to my thinking as I'm in no way sure if it's feasible--I'm just not aware of why it couldn't be used as a backing material.
I too have the same doubt. How about the conductive polymers? Please share if you have information about how the conductive polymer technology is progressing or any other technology that might take place of the LCD.
A lot can happen in 5 years. For the past decade and more, someone has always been predicting rollable flexible, and even wearable, displays "in a few years". Sure, someday one will finally come along. I doubt it will be LCD.
Imagining...someday in the morning we only will need to switch the power on our electronic newspaper...or students will need to carry only one book to the school for all subjects (might have only one page?)...shall save the trees as well! :-)
Remember the old pull-down projector screens in class rooms and conference rooms? Those settings would require somewhat larger versions of the roll-up display, but the usefulness would be the same. Have the display out when you need it. Hide it when you don't.
For smaller systems, like phones and note books, a roll-up screen could dramatically improve on the portability as well as reduce the weight. The only down side is that for all of those folks browsing the web on mini-smartphone screens, the market for reading glasses could go away with a light-weight, roll-up display.
It was also in the movie, "Red Planet", (probably one of the coolest things in the film). There is a scene where the astronauts pull out these large rollable displays out of their pockets to create a 180 degree overlay of the GPS map on the visible landmarks. They better hurry up getting this to market though before they perfect the wearable (wireless power and signal, disposable) contact lens display.
In the late 90's, there was a cheesy syndicated sci-fi show called "Earth: Final Conflict" based on an old idea from Gene Roddenberry of Star Trek (his widow pursued the idea). Set in 2015, people were predicted to use roll-away video phones with pull-out screens that were easier to carry and store than even the emerging candy-bar or clamshell (e.g., StarTac!) models that were then appearing.
A bit of Googling shows that Wistron (part of Acer) bought the bankrupt Polymer Vision, and Wistron is in a joint venture with AU Optronics, mentioned in the article. So the rollable ebook may be back next year.
The advantage is that you could pull a 14" rolled up display out of your pocket, hook it up to your iPhone, and watch a movie.
Polymer Vision created Readius, pocket ebook that used a rollable display, but they went bankrupt before selling the product.
It's not clear to me what the big advantage with in flexibility, except in the presumption that lighter displays will also be more reliabile and potentially less expensive. Most displays tend to be flat. Perhaps something high resolution and wearable?
