  • METHOD FOR INTEGRATING A LIGHT EMITTING DEVICE
    Publication number: 20170125392
    Abstract: Light emitting devices and methods of integrating micro LED devices into light emitting device are described. In an embodiment a light emitting device includes a reflective bank structure within a bank layer, and a conductive line atop the bank layer and elevated above the reflective bank structure. A micro LED device is within the reflective bank structure and a passivation layer is over the bank layer and laterally around the micro LED device within the reflective bank structure. A portion of the micro LED device and a conductive line atop the bank layer protrude above a top surface of the passivation layer.

  • Method of fabricating a light emitting diode display with integrated defect detection test
    Patent number: 9252375
    Abstract: A display panel and method of manufacture are described. In an embodiment, a display substrate includes a pixel area and a non-pixel area. An array of subpixels and corresponding array of bottom electrodes are in the pixel area. An array of micro LED devices are bonded to the array of bottom electrodes. One or more top electrode layers are formed in electrical contact with the array of micro LED devices. In one embodiment a redundant pair of micro LED devices are bonded to the array of bottom electrodes. In one embodiment, the array of micro LED devices are imaged to detect irregularities.
