Abstract
The disclosure relates to an organic light emitting diode, a method for manufacturing the same, and a display panel. The organic light emitting diode includes: a first electrode; a second electrode disposed opposite to the first electrode; a light-emitting layer between the first electrode and the second electrode; the light-emitting layer includes a first light-emitting sub-layer and a second light-emitting sub-layer; the first light-emitting sub-layer includes a host material, a TADF sensitizer and a fluorescent guest material; the second light-emitting sub-layer includes the host material or includes the host material and the TADF sensitizer. The light-emitting layer of the organic light emitting diode of the present disclosure includes the first light-emitting sub-laver and the second light-emitting sub-layer, and thus the luminous efficiency of the red light-emitting device, the green light-emitting device, and the blue light-emitting device can be harmonized by effectively adjusting a thickness of the second light-emitting sub-layer.
