Abstract: Various applications and customizations of a thin flexible LED light sheet are described. Microscopic LED dice are printed on a thin substrate, and the LEDs are sandwiched between two conductor layers to connect the LEDs in parallel. The conductor layer on the light emitting side is transparent. In one embodiment, the light sheet is applied to the bottom surface of a controllable display to serve as a backlight. In another embodiment, the light sheet is applied to the edge of a leaky light guide for backlighting. In another embodiment, a thin light-emitting edge of the light sheet is coupled to the edge of the leaky light guide for backlighting. In another embodiment, the light sheet is affixed to a medical instrument, and light is emitted from a thin light-emitting edge of the light sheet.

Abstract: A method of forming a light sheet includes printing a layer of inorganic LEDs on a first conductive surface of a substrate, depositing a first dielectric layer, and depositing a second conductor layer over the LEDs so that the LEDs are connected in parallel. At least one of the first conductive surface or the second conductor layer is transparent to allow light to escape. A phosphor layer may be formed over the light sheet so that the LED light mixed with the phosphor light creates white light. The flat light sheet is then folded, such as by molding, to form a three-dimensional structure with angled light emitting walls and reflective surfaces to control a directionality of the emitted light and improve the mixing of light. The folds may form rows of angled walls or polygons.

Abstract: Relatively small, electrically isolated LED tiles or PV tiles are fabricated having an anode electrode and a cathode electrode. The LED tiles contain microscopic printed LEDs that are connected in parallel by two conductive layers sandwiching the LEDs. The top conductive layer is transparent. Separately formed from the tiles is a large area backplane having a single layer or multiple layers of metal traces connected to backplane electrodes corresponding to the tile electrodes. Multiple tiles are laminated over the backplane's metal pattern to connect the tile electrodes to the backplane electrodes, such as by a conductive adhesive. The backplane metal pattern may connect the tiles in series and/or parallel, or form an addressable circuit for a display. Groups of tiles may be physically connected to each other prior to the lamination to ease handling and alignment. The backplane has power terminals electrically coupled to the metal traces for receiving power.
