  • Semiconductor light emitting device
    Patent number: 7829905
    Abstract: A semiconductor light emitting device for emission of light having a predetermined bandwidth in a primary direction of emission includes a light generating region for the generation of light; and a 1-dimensional photonic crystal structure having a photonic bandgap covering at least a segment of said bandwidth. The 1-dimensional photonic crystal structure is located such that upon incident of light from the light generating region, light having a wavelength within the bandgap of the 1-dimensional photonic crystal structure is reflected in the primary direction of emission.
    Type: Grant
    Filed: September 7, 2006
    Date of Patent: November 9, 2010
    Assignee: Hong Kong Applied Science and Technology Research Institute Co., Ltd.
    Inventors: Yan Huang, Kuo-An Chiu, Hua-Jun Peng, Jian Feng, Hung-Shen Chu
  • Anode for organic light emitting diode
    Patent number: 7402947
    Abstract: An organic light emitting diode consisting of multiple organic layers, disposed between a transparent conducting anode and metallic cathode. The anode is provided with a metal fluoride layer to enhance the overall performance of the device, including higher power efficiency, lower voltage threshold and improved device operation stability.
