Patent ID: 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 φ1 of the first dopant and a work function φ4 of the cathode satisfy: φ1<φ4, and a work function φ2 of the second dopant and a work function φ3 of the anode satisfy: φ2>φ3.
