Apple's Latest Patent Shows Off Solar Cell Ambient Light Sensors

Apple's latest patent shows off a new technology that would bring solar cells into ambient light sensors found in iPhones, iPads and Macs. The patent was filed back in December of 2012, but was just published today.

Apple currently uses ambient light sensors to detect the amount of light in the environment and to adjust the brightness of the display based on the amount of light. With an ambient light sensor doubling as a solar cell, Apple could charge the user's device throughout the day.

An electronic device is provided with a display and a solar cell ambient light sensor that receives light through a portion of the display. The solar cell ambient light sensor may include one or more thin-film photovoltaic cells. A voltage that accumulates within the thin-film photovoltaic cell in response to ambient light is sampled and converted into ambient light data. The device includes control circuitry that modifies the intensity of display light generated by the display based on the ambient light data from the photovoltaic cell. The solar cell ambient light sensor is attached to a transparent cover layer, a color filter layer, or any other layer of the display. When the accumulated voltage is not being sampled for ambient light measurements, the voltage may be used to provide charge to a battery in the device.

While Apple patents don't always make their way into future products, it would make sense for Apple to implement such a technology into a wearable device, like an iWatch. It has been citied that Apple was facing battery issues on its rumored iWatch device, but perhaps the company found other ways to solve that challenge.

Would be cool to turn it off when necessary.

How about some damn patience for you to answer your own question, plus if you opened your newborn eyes as said that to would answer your shit, look at the timeline of when it is released. How many years does it take for a delusioned blushed babitch to figure simple shit out? Kamatis can't figure it out because he knows what he just wants for himself, that's mainly the purpose of thesefoul disgraceful lives of theirs. If anything charges from a low life dump samshit employees take, that's how his charge to get info or in other words, brain fart, that's where he gets mindless weakest gimmicks yet.
