Apple Could Be Looking For The Sun To Power Portable Devices

In the recent years, Apple has come up with some genuinely useful and practical ideas like the click wheel control and its Magsafe magnetic connector; now a patent application has shown that the Cupertino-based firm is looking to add solar panels to its portable devices.

The patent, unearthed by MacRumors, shows that iPods, iTouch and iPhones could supplement their battery life with solar energy captured through solar panels embedded in their LCD screens.

The fact that screens are getting bigger - the iTouch has a 3.5-inch LCD screen - combined with the ever-growing demand for more juice - think of GPS, multi-megapixel cameras and other such features, seem to have convinced Apple engineers that the sun could do the job.

LCD technology though might not be the best candidate for panels integration because of the way it reflects light to boost brightness; OLED is deemed the better of the two and Apple's push into greener technologies could encourage other manufacturers to follow suit.
