    Abstract: Over a flexible substrate are formed column lines for a display. Over the substrate and column lines are formed a reflective hydrophobic mesh defining pixels. Over the mesh and column lines is printed an LED ink containing microscopic LED dies. The LED ink de-wets from the mesh. The ink is then cured to electrically connect the bottom electrodes of the LEDs to the column lines within the openings (cells) of the mesh. A dielectric then encapsulates the LEDs while exposing the top electrodes of the LEDs. Transparent row lines are then formed along the rows of the mesh to electrically contact the top electrodes in each row. The LEDs within any cell can be turned on by address in a pair of row and column lines. Phosphor dots may be printed to over blue-emitting LEDs to create red, green, and blue sub-pixels for a full color display.

    Abstract: LED modules are disclosed having a control MOSFET, or other transistor, in series with an LED. In one embodiment, a MOSFET wafer is bonded to an LED wafer and singulated to form thousands of active 3-terminal LED modules with the same footprint as a single LED. Despite the different forward voltages of red, green, and blue LEDs, RGB modules may be connected in parallel and their control voltages staggered at 60 Hz or greater to generate a single perceived color, such as white. The RGB modules may be connected in a panel for general illumination or for a color display. A single dielectric layer in a panel may encapsulate all the RGB modules to form a compact and inexpensive panel. Various addressing techniques are described for both a color display and a lighting panel. Various circuits are described for reducing the sensitivity of the LED to variations in input voltage.

    Abstract: 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.

    Abstract: A PV module is formed having an array of PV cells, where the cells are separated by gaps. Each cell contains an array of small silicon sphere diodes (10-300 microns in diameter) connected in parallel. The diodes and conductor layers may be patterned by printing. A continuous metal substrate supports the diodes and conductor layers in all the cells. A dielectric substrate is laminated to the metal substrate. Trenches are then formed by laser ablation around the cells to sever the metal substrate to form electrically isolated PV cells. A metallization step is then performed to connect the cells in series to increase the voltage output of the PV module. An electrically isolated bypass diode for each cell is also formed by the trenching step. The metallization step connects the bypass diode and its associated cell in a reverse-parallel relationship.
