Abstract: Provided are an organic light-emitting element and a display device including the same. The organic light-emitting element includes an anode, a cathode and at least two light-emitting units disposed between the anode and the cathode, where each of the at least two light-emitting units independently includes a light-emitting layer. At least one light-emitting layer includes a first light-emitting sublayer, a second light-emitting sublayer and a spacer layer disposed between the first light-emitting sublayer and the second light-emitting sublayer. A mass percentage content of a first doped material in the first light-emitting sublayer>a mass percentage content of a third doped material in the spacer layer, and a mass percentage content of a second doped material in the second light-emitting sublayer>the mass percentage content of the third doped material in the spacer layer.

Abstract: Provided are an organic compound and use thereof. Specifically, an organic compound, an OLED display panel, and an electronic device are provided. The organic compound has a structure shown in Formula (I); the OLED display panel comprises a first electrode, a second electrode, and an organic thin film layer provided between the first electrode and the second electrode; the organic thin film layer comprises a light-emitting layer; and a host material of the light-emitting layer comprises any one or a combination of at least two of the organic compounds; and the electronic device comprises the OLED display panel. The compound, when used as a host material of the light-emitting layer for the preparation of an OLED device, can reduce the driving voltage of the device, and improve the luminous efficacy and lifetime of the device.
