| 20100033088 | HETEROCYCLIC COMPOUND AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING THE SAME - Provided are a heterocyclic compound represented by Formula 1 below and an organic electroluminescent device including an organic layer comprising the heterocyclic compound: | 02-11-2010 |
| 20100051924 | FLUORENE-CONTAINING COMPOUND AND ORGANIC LIGHT EMITTING DEVICE EMPLOYING THE SAME - A novel fluorene-containing compound and an organic electroluminescent device including an organic layer employing the same. The fluorene-containing compound has excellent electrical characteristics and an excellent charge transporting capability, and so can be used as a hole injecting material, hole transporting material, and/or emitting material that is suitable for all-color fluorescent and phosphorescent devices, such as red, green, blue, and white fluorescent and phosphorescent devices. Accordingly, an organic electroluminescent device employing the fluorene-containing compound has high efficiency, a low driving voltage, high brightness, and a long lifetime. | 03-04-2010 |
| 20110084254 | POLYMER AND ORGANIC LIGHT-EMITTING DEVICE INCLUDING THE SAME - A polymer and an organic light-emitting device including the polymer. An example of the polymer is | 04-14-2011 |
| 20110240968 | Organic light-emitting device - An organic light-emitting device including a substrate; a first electrode on the substrate, the first electrode including a first surface and a second surface opposite to the first surface; an organic layer on the first electrode, the organic layer being adjacent to the first surface of the first electrode; a second electrode on the organic layer, the second electrode including a first surface adjacent to the organic layer and a second surface opposite to the first surface; and a luminescent efficiency improvement layer on at least one of the second surface of the first electrode and the second surface of the second electrode, the luminescent efficiency improvement layer including a condensed-cyclic compound represented by Formula 1, below: | 10-06-2011 |
| 20110240975 | POLYMER COMPOUND AND ORGANIC LIGHT-EMITTING DEVICE INCLUDING THE SAME - A polymer represented by Formula 1 below: | 10-06-2011 |
| 20110240979 | CONDENSED-CYCLIC COMPOUND AND ORGANIC LIGHT-EMITTING DEVICE INCLUDING THE SAME - A condensed-cyclic compound and an OLED including the same, the condensed-cyclic compound represented by Formula 1 below: | 10-06-2011 |
| 20120013246 | DENDRIMER AND ORGANIC LIGHT-EMITTING DEVICE USING THE SAME - A dendrimer and an organic light-emitting device including an organic layer having the dendrimer. | 01-19-2012 |
| 20120013247 | DENDRIMER AND ORGANIC LIGHT-EMITTING DEVICE USING THE SAME - A dendrimer and an organic light-emitting device including an organic layer having the dendrimer. | 01-19-2012 |
