Patents by Inventor Suk Woon Jun

Suk Woon Jun has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10138201
    Abstract: This invention relates to a compound for an organic electroluminescent device and to an organic electroluminescent device including the same. This compound for an organic electroluminescent device has high thermal stability, high triplet energy and high hole transport capability, and the organic electroluminescent device including the same is improved in thermal stability and light emission efficiency. When this compound is used as a hole transport layer material, a triplet exciton of a phosphorescent light emitting material is confined, thus improving efficiency of the organic electroluminescent device.
