Abstract

An organic light-emitting diode (OLED) includes: a first electrode, a first light-emitting layer disposed on a side of the first electrode, a charge generation layer disposed on a side, away from the first electrode, of the first light-emitting layer, a second light-emitting layer disposed on a side, away from the first light-emitting layer, of the charge generation layer, and a second electrode disposed on a side, away from the charge generation layer, of the second light-emitting layer. The OLED further includes: a process conversion layer, disposed between the first electrode and the second electrode, and configured to fill an uneven region between the first electrode and the second electrode.
