Patent ID: 10756304

Abstract:
An organic light-emitting display panel and a display device are provided. The light-emitting display panel includes a first electrode layer including a reflective electrode, and a second electrode layer arranged opposite to the first electrode layer and including a semi-reflective electrode. The light-emitting display panel also includes a light-emitting material layer between the two electrode layers. The second electrode layer has a first side facing the light-emitting material layer and an opposing second side. Further, the light-emitting display panel includes a light-coupling layer group disposed on the opposing second side of the second electrode layer. The light-coupling layer group includes at least one light-coupling stacked layer including a first light-coupling layer arranged close to the second electrode layer and a second light-coupling layer arranged far away from the second electrode layer. A refractive index of the first light-coupling layer is larger than a refractive index of the second light-coupling layer.
