Patent ID: 11877461

Abstract:
Embodiments of the present disclosure provide a light emitting diode device, a display panel, a display device, and a manufacturing method. The light emitting diode device includes: a base substrate; a first electrode disposed on one side of the base substrate; a carrier functional layer disposed on one side, facing away from the base substrate, of the first electrode; a quantum dot light emitting layer disposed on one side, facing away from the first electrode, of the carrier functional layer, having a molecular chain structure inside, where the molecular chain structure is formed by atom transfer radical polymerization of a first reactant and a modified molecule, the first reactant undergoes atom transfer radical polymerization with the modified molecule through a ligand molecule A, and in an initial state, the modified molecule is connected to one surface, facing the quantum dot light emitting layer, of the carrier functional layer; and a second electrode disposed on one side, facing away from the carrier functional layer, of the quantum dot light emitting layer.
