  • Organic light emitting device and display device using the same
    Patent number: 11956980
    Abstract: Discussed is an organic light emitting device in which a light emitting layer includes a host and different kinds of dopants, the fluorescent dopant is formed of a material having energy level properties facilitating thermally activated delayed fluorescence (TADF), and thus energy is concentratedly transferred to the fluorescent dopant so as to increase luminous efficacy of a single color.
    Type: Grant
    Filed: December 24, 2020
    Date of Patent: April 9, 2024
    Assignee: LG DISPLAY CO., LTD.
    Inventors: Gyeong-Woo Kim, Hong-Seok Choi, Seung-Ryong Joung, Jun-Ho Lee, Yoon-Deok Han, Hee-Su Byeon
  • Display panel and head mounted display device having the same
    Patent number: 11828943
    Abstract: Disclosed are a display panel which changes the inner structure of an organic light emitting stack and a color transmission structure so as to improve luminance, and a head mounted display device using the same.
    Type: Grant

  • WHITE LIGHT EMITTING DEVICE AND DISPLAY DEVICE USING THE SAME
    Publication number: 20230217671
    Abstract: A white light emitting device, or more particularly an inverted white light emitting device, includes a plurality of stacks configured to emit white light, and an optical compensation layer provided at an outer surface of an electrode through which light is emitted to the outside. The configuration reduces the thickness of an electron transport layer adjacent to a cathode in the stack and therefore reduces the driving voltage and improves the viewing angle characteristics and as well as the efficiency.

  • Boron-nitride nanoplatelet(s)/metal nanocomposite powder and preparing method thereof
    Patent number: 11285532
    Abstract: Provided are a boron-nitride nanoplatelet(s) (BNNP)/metal nanocomposite powder and a preparing method thereof, the BNNP/metal nanocomposite powder including a base metal and BNNP dispersed in the base metal and configured to serve as a reinforcement of the base metal, wherein the BNNP are interposed between metal particles of the base metal in the form of a thin film of a plurality of layers and combined with the metal particles, and an amount of the BNNP in the base metal is greater than 0 vol % and less than 90 vol %.
