Will LG be the first to launch a flexible screen for electronic readers? The company has announced that it has begun production of this electronic paper and that it should be on sale this April.
The flexible 6-inch screen with 1024×768 pixels is 100% plastic and unbreakable. The screen is both light (14 grammes) and thin (0.7 mm) and like most current readers, works with electronic ink.
Each cell, comparable in size to a human hair, contains a liquid in which black and white particles float. The polarised black particles are attracted by positive charges and the white by negatives. The greys are created by a play on the voltage applied to electrodes on either side of these cells.
While the basic principle (variable voltage applied to polarised elements) is close to the technology used for LCD screens, there is a fundamental difference. No backlighting is needed here, which is how the screen can be so thin and transparent.
The major electronics players such as Samsung, IBM, Lucent and Philips have been working on this flexible technology for years but LG is the first to bring out products using the much-anticipated formula which may well entirely transform the hardware used for our readers. This screen can be bent up to 40° (not yet enough to fold in two and put in your pocket!). What will the next stage be? A flexible colour screen perhaps?
