Flexible displays can create a wraparound immersive experience for the viewer -- similar to the Imax theater experience. Curved screen technology can also make mobile devices easier to carry, and it could provide auxiliary screens that are as easy to transport as a blueprint.
The prototype 18-inch display had just short of 1 million pixels in a 1,200-by-800 configuration with a curvature radius of 30R, allowing it to be rolled into about a scroll a little over an inch without damage and while still working. For the future, LG is trying to increase the screen size to 60 inches while increasing its curvature radius to 50R or a scroll a little less than two inches.
Unlike LCDs, whose typical transmittance is around 10%, LG's device offers a transmittance of 30%.
The transparent backplane for LG's display will allow mid-air applications -- for displaying tactical data on its transparent polyimide backplane, which minimizes the thickness of the display and makes it more flexible. Commercial applications, besides sci-fi like tactical displays, could be for refrigerator doors, where you could see the food inside, along with information such as temperature or even advertisements.
LG says that, by using special circuit devices and film components, it achieved 30% transmittance (compared with 10% for LCDs) and lowered haze to 2%.
