From Yahoo News:
LG Display unveiled a paper thin, 18-inch television panel prototype that can be rolled up into the shape of a thin cylinder, making television portable.
The panel has almost 1 million megapixels and can be rolled up into a cylinder with a 2.4-inch diameter without affecting its high-definition display.
Instead of using "conventional plastic" for the backbone of the screen, the company said it used polyimide film. The material drastically reduced the screen's thickness and gave it the flexibility needed to roll it into a tight cylinder.
Along with the flexible screen, LG showed off a transparent panel that has a significantly clearer picture quality than existing see-through LCD displays.
LG Display said the technological advancement proves they can produce rollable television screens larger than 50 inches diagonally. In a statement, the company said it is confident it will produce a 60-inch Ultra HD, transparent rollable television by 2017.I don't know if this will be as significant for televisions as it will be for mobile phones and tablets. Being able to extend or retract a screen to the size you need would be extremely handy--it would allow you to have the benefit of larger screen when you need it without having to carry a bulkier phone or tablet. The 2.5 inch diameter of the tube needs to be reduced further, though.
