Abstract

The present application discloses an organic light emitting diode including a light emitting layer; a first electron transport layer including a first electron transport material on the light emitting layer; a hole scavenger layer including a hole scavenger material on a side of the first electron transport layer distal to the light emitting layer; and a second electron transport layer including a second electron transport material on a side of the hole scavenger layer distal to the first electron transport layer. The hole scavenger material includes a first light emitting material capable of converting excitons generated by excess holes in the first or second electron transport layer to a ground state through radiative decay.
