This is going to be a fun development in the ebook/ereader saga. The electronic paper display (EPD) is a 6-inch, 1024×768 e-ink plastic screen. It’s 0.7mm thick, it weighs 14g, and LG claims it’s resistant to scratches and drops from a 1.5 meter height. It can bend at a range of 40 degrees from the center of the screen, and it's also about one-third thinner and half as light as current glass EPDs, LG says, meaning it'll be even easier to carry than the e-book readers today.
There are going to be a whole host of uses for this - can anyone say 'Hogwarts newspaper'? Then there's delegate badges, signs that can be instantly changed, and of course if you can put a few of these together you have your electronic ink book.
