The present disclosure relates to an organic light emitting device having improved driving voltage, efficiency and lifetime.
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.
In the organic light emitting devices as described above, there is a continuing need for the development of an organic light emitting device having improved driving voltage, efficiency and lifetime.
It is an object of the present disclosure to provide an organic light emitting device having improved driving voltage, efficiency and lifetime.

A glass substrate on which a thin film of ITO (indium tin oxide) was coated in a thickness of 1,000 Å was put into distilled water containing a detergent dissolved therein and ultrasonically washed. In this case, the detergent used was a product commercially available from Fischer Co. and the distilled water was one which had been twice filtered by using a filter commercially available from Millipore Co. The ITO was washed for 30 minutes, and ultrasonic washing was then repeated twice for 10 minutes by using distilled water. After the washing with distilled water was completed, the substrate was ultrasonically washed with isopropyl alcohol, acetone, and methanol solvent, and dried, after which it was transported to a plasma cleaner. Then, the substrate was cleaned with oxygen plasma for 5 minutes, and then transferred to a vacuum evaporator.
On the ITO transparent electrode thus prepared, the following compound HI-1 was formed in a thickness of 1150 Å as a hole injection layer, but the following compound A-1 was p-doped at a concentration of 1.5 wt. %. The following compound HT-1 was vacuum deposited on the hole injection layer to form a hole transport layer with a film thickness of 800 Å. Then, the following compound EB-1 was vacuum-deposited on the hole transport layer to a thickness of 150 Å to form an electron blocking layer. Then, the previously prepared compound 1-2, compound 2-1 and the following compound Dp-7 were vacuum-deposited in a weight ratio of 49:49:2 on the EB-1 deposited film to form a red light emitting layer with a thickness of 400 Å. The following compound HB-1 was vacuum-deposited on the light emitting layer to a film thickness of 30 Å to form a hole blocking layer. Then, the following compound ET-1 and the following compound LiQ were vacuum-deposited in a weight ratio of 2:1 on the hole blocking layer to form an electron injection and transport layer with a thickness of 300 Å. Lithium fluoride (LiF) and aluminum were sequentially deposited to have a thickness of 12 Å and 1,000 Å, respectively, on the electron injection and transport layer, thereby forming a cathode.
In the above-mentioned processes, the deposition rates of the organic materials were maintained at 0.4-0.7 Å/sec, the deposition rates of lithium fluoride and the aluminum of the cathode were maintained at 0.3 Å/sec and 2 Å/sec, respectively, and the degree of vacuum during the deposition was maintained at 2×10−7˜5×10−6 torr, thereby manufacturing an organic light emitting device.
The organic light emitting devices were manufactured in the same manner as in Example 1, except that the first host compound and the second host compound described in Tables 1 to 5 were co-deposited and used in a 1:1 ratio instead of Compound 1-2 and/or Compound 2-1 used in the organic light emitting device of Example 1.
The organic light emitting devices were manufactured in the same manner as in Example 1, except that the first host compound and the second host compound described in Tables 6 and 7 were co-deposited and used in a 1:1 ratio instead of Compound 1-2 and/or Compound 2-1 used in the organic light emitting device of Example 1. The structures of Compound B-1 to Compound B-12 in Tables 6 and 7 are as follows.
The organic light emitting devices were manufactured in the same manner as in Example 1, except that the first host compound and the second host compound described in Tables 8 and 9 were co-deposited and used in a 1:1 ratio instead of Compound 1-2 and/or Compound 2-1 used in the organic light emitting device of Example 1. The structures of Compound C-1 to Compound C-9 in Tables 8 and 9 are as follows.
The driving voltage and efficiency were measured (15 mA/cm2) by applying a current to the organic light emitting devices manufactured in Examples 1 to Example 200 and Comparative Example 1 to Comparative Example 132, and the results are shown in Table 1 to Table 9 below. Lifetime T95 was measured based on 7000 nits, and T95 means the time required for the lifetime to be reduced to 95% of the initial lifetime.
When a current was applied to the organic light emitting devices manufactured in Examples 1 to 200 and Comparative Examples 1 to 132, the results shown in Table 1 Table 9 were obtained. A material widely used in the prior art was used as a component of the red organic light emitting device of Example 1, Compound EB-1 was used as the electron blocking layer, and Compound Dp-7 was used as the dopant of the red light emitting layer.
When any one of Comparative Example Compounds B-1 to B-12 and the compound of Chemical Formula 2 of the present disclosure were co-deposited together and used as a red light emitting layer as shown in Table 6 and Table 7, the result showed that generally, the driving voltage increased and the efficiency and lifetime decreased as compared with the combination of the present disclosure. Even when any one of Comparative Example Compounds C-1 to C-9 and the compound of Chemical Formula 1 of the present disclosure were co-deposited together and used as a red light emitting layer as shown in Table 8 and Table 9, the result showed that the driving voltage increased and the efficiency and lifetime decreased.
From the above, it can be seen that when the compound of Chemical Formula 1 as the first host and the compound of Chemical Formula 2 as the second host according to the present disclosure were used in combination, energy transfer to the red dopant in the red light emitting layer was well achieved, the electrons and holes were combined through a more stable balance in the light emitting layer to form excitons, and thus, the driving voltage is improved and the efficiency and lifetime are increased.
In conclusion, when the compound of Chemical Formula 1 and the compound of Chemical Formula 2 according to the present disclosure are combined, co-evaporated and used as a host for the red light emitting layer, it was confirmed that the driving voltage, luminous efficiency, and lifetime characteristics of the organic light emitting device could be improved.
