STACKED ORGANIC LIGHT-EMITTING DIODE |
摘要 |
<p>The present invention provides a stacked organic light emitting diode that comprises a first electrode; a second electrode; and at least two light emitting units that are located between the first electrode and the second electrode. The light emitting unit satisfies the following energy relation equation, and includes an n-type organic layer and a p-type organic layer that form NP conjunction, and also includes an n-type doped organic layer that is located between the light emitting units: E p �¢ H - E nL ‰¤ 1 �¢ eV
wherein E nL is a LUMO (lowest unoccupied molecular orbital) energy level of the n-type organic layer and E pH is a HOMO (highest occupied molecular orbital) energy level of the p-type organic layer.</p> |
