Organic Light-Emitting Display Device

摘要

An organic light-emitting display (OLED) device is disclosed that includes: a red organic light-emitting diode comprising a red organic emission layer; a green organic light-emitting diode comprising a green organic emission layer; and a blue organic light-emitting diode comprising a blue organic emission layer. The difference between a peak of a photoluminescence spectrum of the red organic emission layer and a peak of an electroluminescence spectrum of the red organic light-emitting diode is less than 2 nm, the difference between a peak of a PL spectrum of the green organic emission layer and a peak of an EL spectrum of the green organic light-emitting diode is less than 2 nm, and the difference between a peak of a PL spectrum of the blue organic emission layer and a peak of an EL spectrum of the blue organic light-emitting diode is 4 nm or greater.

1. An organic light-emitting display (OLED) device, comprising:
a red organic light-emitting diode; a green organic light-emitting diode; a blue organic light-emitting diode comprising a blue organic emission layer, wherein a difference (ΔLB) between a peak of a photoluminescence (PL) spectrum of the blue organic emission layer (B_PLλmax) and a peak of an electroluminescence (EL) spectrum of the blue organic light-emitting diode (B_ELλmax) is 4 nm or greater in an optical distance of the blue organic light-emitting diode.
