The present disclosure relates to an organic light emitting device.
In general, an organic light emitting phenomenon refers to a phenomenon where electric energy is converted into light energy by using an organic material. The organic light emitting device using the organic light emitting phenomenon has characteristics such as a wide viewing angle, an excellent contrast, a fast response time, an excellent luminance, driving voltage and response speed, and thus many studies have proceeded.
The organic light emitting device generally has a structure which comprises an anode, a cathode, and an organic material layer interposed between the anode and the cathode. The organic material layer frequently has a multilayered structure that comprises different materials in order to enhance efficiency and stability of the organic light emitting device, and for example, the organic material layer can be formed of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and the like. In the structure of the organic light emitting device, if a voltage is applied between two electrodes, the holes are injected from an anode into the organic material layer and the electrons are injected from the cathode into the organic material layer, and when the injected holes and electrons meet each other, an exciton is formed, and light is emitted when the exciton falls to a ground state again.
There is a continuing need for the development of new materials for the organic materials used in the organic light emitting devices as described above.
The present disclosure relates to an organic light emitting device having improved driving voltage, efficiency, and lifespan.

Then, the following Compound HT-1 was vacuum-deposited on the hole injection layer to a thickness of 800 Å to form a hole transport layer. Thereafter, the following Compound EB-1 was vacuum-deposited on the hole transport layer to a thickness of 150 Å as an electron blocking layer. Then, Compound 1-2, Compound 2-1, and the following Compound Dp-7 were vacuum-deposited on the EB-1 deposited film to a thickness of 400 Å in a weight ratio of 49:49:2 to form a red light emitting layer. A hole blocking layer was formed by vacuum-depositing the following Compound HB-1 to a thickness of 30 Å on the light emitting layer. Then, the following Compound ET-1 and the following Compound LiQ were vacuum-deposited on the hole blocking layer to a thickness of 300 Å in a weight ratio of 2:1 to form an electron injection and transport layer. Lithium fluoride (LiF) and aluminum were sequentially deposited on the electron injection and transport layer to a thickness of 12 Å and 1,000 Å, respectively, to form a cathode.
In the above process, the deposition rate of the organic material was maintained at 0.4 to 0.7 Å/sec, the deposition rate of lithium fluoride of the cathode was maintained at 0.3 Å/sec, and the deposition rate of aluminum was maintained at 2 Å/sec. In addition, the degree of vacuum during the deposition was maintained at 2×10−7 to 5×10−6 torr, thereby manufacturing an organic light emitting device.
Organic light emitting devices were manufactured in the same manner as in Example 1, except that the compounds shown in Table 1 were used instead of Compound 1-2 and Compound 2-1.
Organic light emitting devices were manufactured in the same manner as in Example 1, except that the compounds shown in Table 2 were used instead of Compound 1-2 and Compound 2-1.
Organic light emitting devices were manufactured in the same manner as in Example 1, except that the compounds shown in Table 3 were used instead of Compound 1-2 and Compound 2-1.
The Compounds B-1 to B-12 and C-1 to C-8 used in Comparative Examples 1 to 124 are as follows.
The driving voltage, efficiency, and lifespan were measured by applying a current of 15 mA/cm2 to the organic light emitting devices prepared in the above Examples 1 to 145 and Comparative Examples 1 to 124. The lifespan T95 means the time (hr) taken until the initial luminance (6000 nit) decreases to 95%.
The results are shown in Tables 1 to 3 below.
Referring to Tables 1 to 3, it was confirmed that the organic light emitting devices of Examples 1 to 145 in which the compound of Chemical Formula 1 and the compound of Chemical Formula 2 were co-deposited as a host for the red light emitting layer had reduced driving voltage and increased efficiency and lifespan compared to Comparative Examples 1 to 124.
From these results, it can be confirmed that the combination of the compound of Chemical Formula 1 and the compound of Chemical Formula 2 is more effective in energy transfer to the dopant in the light emitting layer compared to the combination of Comparative Examples.
