ORGANIC LIGHT EMITTING DISPLAY APPARATUS |
| 摘要 |
Disclosed is an organic light emitting display (OLED) apparatus with improved efficiency and lifespan, wherein the OLED apparatus includes an anode, a cathode, and a light-emitting unit disposed in-between, wherein the light-emitting unit includes a first emission layer, and a first hole transporting layer having first and second materials, wherein the first material has a higher hole mobility than that of the second material so as to improve a transfer of holes from the first hole transporting layer to the first emission layer, and the second material has a higher triplet energy level than that of the first material so as to reduce a transfer of electrons from the first emission layer to the first hole transporting layer. |

1. An organic light emitting display (OLED) apparatus comprising,
an anode and a cathode; and a light-emitting unit between the anode and the cathode, the light-emitting unit including a first emission layer, and a first hole transporting layer having first and second materials, wherein the first material has a higher hole mobility than that of the second material so as to improve a transfer of holes from the first hole transporting layer to the first emission layer, and the second material has a higher triplet energy level than that of the first material so as to reduce a transfer of electrons from the first emission layer to the first hole transporting layer. |
