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.
