LG Display has unveiled an e-book reader that is equipped
with in-house developed thin-film solar cell. The cell means that the ebook is .7mm in thickness and
weighs 20 grams.
It is thinner than a credit card and about the same
weight of a fountain pen, the company said. It also 10cm in width and length, and it was developed to
fit the 6-inch display panel for the e-book readers currently mass produced by
LG Display.
The thin-film solar cell is produced by placing
electrodes onto a glass or plastic substrate. The solar cell is about 9.6 per cent efficient. What you
would need to do is expose it to sunlight for four or five hours and it will
last a day without additional charging.
The gear is still in the prototype phase so there is no
word on price yet.
