  • Organic electroluminescent device comprising delayed fluorescent materials
    Patent number: 10600983
    Abstract: An organic electroluminescent device containing a cathode, an anode, and one or more organic layers containing plural light emitting materials between the cathode and the anode, wherein the organic electroluminescent device is a multiple wavelength light emitting organic electroluminescent device emitting light from the plural light emitting materials, and which is designed so that light that has the shortest wavelength contains delayed fluorescent light can improve light emission efficiency of a short wavelength light and color tone and has a large degree of freedom in design and a simple structure.
    Type: Grant
