    摘要: An initially flat light sheet is formed by printing conductor layers and microscopic LEDs over a flexible substrate to connect the LEDs in parallel. The light sheet is then subjected to a molding process which forms 3-dimensional features in the light sheet, such as bumps of any shape. The features may be designed to create a desired light emission profile, increase light extraction, and/or create graphical images. In one embodiment, an integrated light sheet and touch sensor is formed, where the molded features convey touch positions of the sensor. In one embodiment, a curable resin is applied to the light sheet to fix the molded features. In another embodiment, optical features are molded over the flat light sheet. In another embodiment, each molded portion of the light sheet forms a separate part that is then singulated from the light sheet.

    摘要: In a method for forming a phosphor-converted LED, an array of vertical LEDs is printed over a conductive surface of a substrate such that a bottom electrode of the LEDs ohmically contacts the conductive surface. A dielectric layer then formed over the conductive surface. An electrically conductive phosphor layer is deposited over the dielectric layer and the LEDs to ohmically contact the top surface of the LEDs and connect the LEDs in parallel. The conductive phosphor layer is formed by phosphor particles intermixed with a transparent conductor material. One or more metal contacts over the conductive phosphor layer conduct current through the conductive phosphor layer and the LEDs to illuminate the LEDs. A portion of light generated by the LED leaks through the conductive phosphor layer, and the combination of the LED light and phosphor light creates a composite light.

    摘要: 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.
