Abstract
The OLED display device includes a first stack and a second stack that are separated from each other between an anode electrode and a cathode electrode, with a charge generation layer sandwiched between the first stack and the second stack, each of the first stack and the second stack having an emission layer. The first stack includes a blue emission layer formed between the anode electrode and the CGL. The second stack includes a fluorescent green emission layer and a phosphorescent red emission layer formed between the cathode electrode and the CGL. The blue emission layer includes one of a fluorescent blue emission layer and a phosphorescent blue emission layer.
Claims3
An organic light emitting diode display device comprising:
- a first stack and a second stack that are separated from each other between an anode electrode and a cathode electrode, with a charge generation layer (CGL) sandwiched between the first stack and the second stack, each of the first stack and the second stack including at least one emission layer,
- wherein the emission layer of the first stack includes only a fluorescent blue emission layer formed between the anode electrode and the CGL, and the emission layer of the second stack includes a fluorescent green emission layer and a phosphorescent red emission layer stacked in a hybrid structure between the cathode electrode and the CGL.
