Abstract
A display with a photovoltaic (PV) cells integrated as the front side and/or back side of the display is disclosed. Ambient light may reach a PV cell situated behind a display through fully or partially transmissive features within the display. Display-generated light may also reach a PV cell behind a display. A transmissive PV material situated in front of a display may collect both ambient light as well as display-generated light.
Claims16
A display device configured to display an image toward a front side, with a back side opposite the front side, the display device comprising:
- a transparent substrate having a front side and a back side;
- a display comprising an array of addressable pixels in an image region of the display, the addressable pixels being formed on a back side of the substrate, wherein array of addressable pixels includes interferometric modulators;
- and
- a photovoltaic cell comprising a blanket layer of photovoltaic material formed on a front side of the substrate, wherein the blanket layer is disposed in front of the addressable pixels in the image region.
A display device configured to display an image toward a front side, with a back side opposite the front side, the display device comprising:
- a transparent substrate;
- a display comprising an array of addressable interferometric modulator pixels in an image region, the display being formed on the back side of the substrate;
- and
- a photovoltaic cell comprising a photovoltaic material formed over the front side of the interferometric modulator pixels in the image region, wherein the photovoltaic material is a blanket layer.
A method of manufacturing a display device, the display device capable of displaying an image toward a front side, with a back side opposite the front side, the method comprising:
- forming a display comprising an array of addressable pixels in an image region on a transparent substrate, wherein the array is formed on the back side of the substrate and the array of addressable pixels includes interferometric modulators;
- and
- disposing a blanket photovoltaic material on the front side of the substrate over the front side of the display in the image region.
