Light-recycling within electronic displays using deep red and near infrared photoluminescent polarizers

We report a linearly polarized luminescent solar concentrator with broad absorption across the visible, and luminescence beyond the emissive spectrum of the display. When used to replace a conventional polarizer in a luminescent display, this device recycles light absorbed by the polarizer, guiding...

Summary:We report a linearly polarized luminescent solar concentrator with broad absorption across the visible, and luminescence beyond the emissive spectrum of the display. When used to replace a conventional polarizer in a luminescent display, this device recycles light absorbed by the polarizer, guiding it to the frame of the display where solar cells may be mounted. A linearly polarized luminescent solar concentrator harnesses ambient light and recycles the unwanted polarization component of the backlight in electronic displays, potentially extending the battery life of mobile devices.
