摘要： A light emitting device and method for making the same are disclosed. The device includes an active layer disposed between first and second layers. The first layer has top and bottom surfaces. The top surface includes a first material of a first conductivity type, including a plurality of pits in the substantially planar surface. The active layer overlies the top surface of the first layer and conforms to the top surface, the active layer generating light characterized by a wavelength when holes and electrons recombine therein. The second layer includes a second material of a second conductivity type, the second layer overlying the active layer and conforming to the active layer. The device can be constructed on a substrate having a lattice constant sufficiently different from that of the first material to give rise to dislocations in the first layer that are used to form the pits.

摘要： An electrode structure is disclosed for enhancing the brightness and/or efficiency of an LED. The electrode structure can have a metal electrode and an dielectric material formed intermediate the electrode and a light emitting semiconductor material. Electrical continuity between the semiconductor material and the metal electrode is provided by an optically transmissive ohmic contact layer, such as a layer of Indium Tin Oxide. The metal electrode thus can be physically separated from the semiconductor material by one or more of the dielectric material and the ohmic contact layer. The dielectric layer can increase total internal reflection of light at the interface between the semiconductor and the dielectric layer, which can reduce absorption of light by the electrode. Such LED can have enhanced utility and can be suitable for uses such as general illumination.

摘要： A light source and method for making the same are disclosed. The light source includes a substrate and a light emitting structure that is deposited on the substrate. A barrier divides the light emitting structure into first and second segments that are electrically isolated from one another. A serial connection electrode connects the first segment in series with the second segment. A first blocking diode between the light emitting structure and the substrate prevents current from flowing between the light emitting structure and the substrate when the light emitting structure is emitting light. The barrier extends through the light emitting structure into the first blocking diode.

摘要： The invention is an AlInGaN light-emitting device (LED) that includes a p-type contact made of highly-reflective material with closely-spaced openings that increase light extraction efficiency. The minimum dimension of the openings is ¼ of the wavelength of the emitted light and is preferably comparable to the distance current flows laterally in the p-layers of the device. The openings in the metal occupy 20-80% of the top surface of the contact and are finely spaced to achieve transparency and uniform light emission. An optional dielectric encapsulant may be deposited over the p-type contact to improve the contact's adhesion by tacking it down at regular intervals, and to improve light extraction. The surface of the epitaxial layers may be etched in the openings to scatter light in the semiconductor, increasing light extraction. A reflective layer may be applied to the bottom surface of the LED to increase the light extraction efficiency.

摘要： This disclosure provides an electroluminescent ("EL") display device having anode, cathode, insulator and organic EL layers. The anode and cathode layers sandwich the other two layers, and the insulator layer is patterned to selectively block flow of current through the EL layers, and thereby locally block generation of light. The patterned insulator layer allows a single panel to display multiple visual attributes, yet does not require electrode patterning. The patterned insulator can be fabricated using photoresist exposure and development procedures. The photoresist is laid on top of a commercially available substrate/electrode layered pair, and is developed to create an assembly that can be completed in a single vacuum deposition process. By etching a small region of the electrode from the commercially available layered pair, and by choosing a deposition frame that blocks deposition on a second, different small region, electrical terminals may be coupled to the panel with a reduced risk of an electrical short.

摘要： A light source and method for making the same are disclosed. The light source includes a plurality of Segmented LEDs connected in parallel to a power bus and a controller. The power bus accepts a variable number of Segmented LEDs. The controller receives AC power and provides a power signal on the power bus. Each Segmented LED is characterized by a driving voltage that is greater than 3 times the driving voltage of a conventional LED fabricated in the same material system as the Segmented LED. The number of Segmented LEDs in the light source is chosen to compensate for variations in the light output of individual Segmented LEDs introduced by the manufacturing process. In another aspect of the invention, the number of Segmented LEDs connected to the power bus can be altered after the light source is assembled.
