Did you know that when you turn on your phone’s display or even a lamp, more light is produced than the amount you need or can even see. So Apple has filed an application for a patent that aims to reduce the production of extra light that isn’t really needed. At the same time, this would reduce the amount of energy used since less light would need to be produced. The bottom line is the possibility that Apple will be able to use more efficient displays on its devices including the iPhone, the Apple Watch, and even Apple Glass. These displays would produce sharper images and could help increase the battery life on these products.
