Researchers Add Solar Cells to OLED Display

Researchers at the University of Cambridge have created a way to harvest some of the light that is wasted within OLED displays, which can lead to a boost in battery life. According to lead researcher Arman Ahnood, 64% of the light created by OLED displays is wasted and escapes through the sides of the display. Ahnood's team decided to place a photovoltaic strip around the edges of the display to capture that light energy. Rather than have the energy charge the battery, Ahnood's team created a thin-film supercapacitor that stores the energy immediately. The net effect is an 11% increase in efficiency that boils down to an output of 5 milliwatts of power for a device with a 3.7-inch display. Right now, the technology only works with OLED displays. The researchers didn't indicate when the development might be mature enough to reach production devices.

That the moment there is more energy, there will be apps that will want to use it.
