  • Organic light-emitting display panel and display device with earth metal dopants
    Patent number: 11605795
    Abstract: Provided are an organic light-emitting display panel and a display device. The organic light-emitting display includes an array substrate and organic light-emitting components each having an anode, a cathode and an organic functional layer. The organic functional layer includes an organic light-emitting layer, a first electron transmission layer, and a hole injection layer. LUMO1 and LUMO4 satisfy: |LUMO1?LUMO4|<1.7 eV. HOMO5 and HOMO4 satisfy: |HOMO5?HOMO4|<1 eV. A work function ?1 of the first dopant and a work function ?4 of the cathode satisfy: ?1<?4, and a work function ?2 of the second dopant and a work function ?3 of the anode satisfy: ?2>?3.
    Type: Grant
