Description

Organic optoelectronic devices and displays

[0001] It relates to organic optoelectronic devices and display devices.

[0002] Organic optoelectronic diodes are devices that can convert electrical energy and light energy to each other.

[0003] Organic optoelectronic devices can be broadly divided into two types based on their operating principles. One type is a photoelectric device, in which excitons formed by light energy are separated into electrons and holes, and the electrons and holes are transferred to different electrodes to generate electrical energy. The other type is a light-emitting device, in which light energy is generated from electrical energy by supplying voltage or current to an electrode.

[0004] Examples of organic optoelectronic devices include organic photovoltaic devices, organic light-emitting devices, organic solar cells, and organic photoconductor drums.

[0005] Among these, organic light-emitting diodes (OLEDs) have recently attracted significant attention due to the increasing demand for flat panel display devices. OLEDs are devices that convert electrical energy into light, and their performance is significantly influenced by the organic materials located between the electrodes.

[0006] One embodiment provides an organic optoelectronic device capable of implementing long-life characteristics.

[0007] Another embodiment provides a display device including the organic optoelectronic device.

[0008] According to one embodiment, an organic optoelectronic device is provided, comprising: an anode and a cathode facing each other; a light-emitting layer positioned between the anode and the cathode; a hole transport layer positioned between the anode and the light-emitting layer; and a hole transport auxiliary layer positioned between the hole transport layer and the light-emitting layer, wherein the hole transport auxiliary layer includes a first hole transport auxiliary layer adjacent to the hole transport layer and a second hole transport auxiliary layer adjacent to the light-emitting layer, wherein the first hole transport auxiliary layer includes a first compound represented by a combination of the following chemical formulae 1 and 2, and the second hole transport auxiliary layer includes a second compound represented by a combination of the following chemical formulae 3 and 4, wherein the first compound and the second compound are different from each other.

[0057] In addition, electronic properties refer to the property of being able to receive electrons when an electric field is applied, and have conductive properties along the LUMO level, which means the property of facilitating the injection of electrons formed at the cathode into the light-emitting layer, the movement of electrons formed in the light-emitting layer to the cathode, and the movement in the light-emitting layer.

[0058] Organic optoelectronic devices are not particularly limited as long as they can convert electrical energy and light energy to each other, and examples thereof include organic photoelectric devices, organic light-emitting devices, organic solar cells, and organic photosensitive drums.

[0059] Here, an organic light-emitting device, which is an example of an organic optoelectronic device, is described as an example, but the present invention is not limited thereto and can be equally applied to other organic optoelectronic devices.

[0060] To clearly illustrate various layers and regions in the drawings, the thicknesses are enlarged. Similar parts are designated by the same drawing reference numerals throughout the specification. When an element, such as a layer, film, region, or plate, is said to be "on" another element, this includes not only the case where it is "directly on" the other element, but also the case where there are other elements in between. Conversely, when an element is said to be "directly on" another element, it means that there are no other elements in between.

[0061] Figure 1 is a cross-sectional view illustrating an organic light-emitting device according to one embodiment.

[0062] An organic light-emitting device according to an embodiment will be described with reference to FIG. 1 below.

[0063] Referring to FIG. 1, an organic light-emitting device according to one embodiment includes an anode (10) and a cathode (20) facing each other, and an organic layer (30) positioned between the anode (10) and the cathode (20).

[0064] The anode (10) can be made of a conductor with a high work function, for example, to facilitate hole injection, and can be made of, for example, a metal, a metal oxide, and / or a conductive polymer. The anode (10) may be, but is not limited to, a metal such as nickel, platinum, vanadium, chromium, copper, zinc, or gold, or an alloy thereof; a metal oxide such as zinc oxide, indium oxide, indium tin oxide (ITO), or indium zinc oxide (IZO); a combination of a metal and an oxide such as ZnO and Al or SnO2 and Sb; a conductive polymer such as poly(3-methylthiophene), poly(3,4-(ethylene-1,2-dioxy)thiophene) (polyethylenedioxythiophene: PEDOT), polypyrrole, and polyaniline.

[0065] The cathode (20) can be made of a conductor with a low work function to facilitate electron injection, for example, and can be made of a metal, a metal oxide, and / or a conductive polymer. The cathode (20) can be made of, for example, a metal such as magnesium, calcium, sodium, potassium, titanium, indium, yttrium, lithium, gadolinium, aluminum, silver, tin, lead, cesium, barium, or an alloy thereof; a multilayer structure material such as LiF / Al, LiO2 / Al, LiF / Ca, and BaF2 / Ca, but is not limited thereto.

[0067] The light-emitting layer (31) includes a host and a dopant, and the host may be, for example, a phosphorescent host.

[0068] A phosphorescent host must facilitate the injection and transport of holes and electrons within the emitting layer, ultimately allowing holes and electrons to meet to form excitons, and must be able to transfer the energy of the formed excitons to the dopant. Examples of phosphorescent hosts include organic compounds containing carbazole, indolocarbazole, dibenzofuran, dibenzothiophene, indolodibenzofuran, indolodibenzothiophene, fluorene, indenocarbazole, triphenylene, pyrimidine, triazine, or combinations thereof.

[0070] The dopant may be, for example, a phosphorescent dopant, for example, a red, green or blue phosphorescent dopant, for example, a red or green phosphorescent dopant.

[0071] A dopant is a substance that causes light emission when mixed in a small amount with a host. Typically, a metal complex that emits light by multiple excitation that excites beyond the triplet state can be used. The dopant may be, for example, an inorganic, organic, or organic-inorganic compound, and may contain one or more types.

[0072] An example of a dopant is a phosphorescent dopant, and examples of a phosphorescent dopant include an organometallic compound containing Ir, Pt, Os, Ti, Zr, Hf, Eu, Tb, Tm, Fe, Co, Ni, Ru, Rh, Pd, or a combination thereof.

[0977] (Fabrication of organic optoelectronic devices)

[0978] Example 1

[0979] A glass substrate coated with a thin film of ITO / Ag / ITO was ultrasonically washed in distilled water. After washing with distilled water, it was ultrasonically washed with a solvent such as acetone or isopropyl alcohol, dried, and then transferred to a plasma cleaner. The substrate was then cleaned for 10 minutes using oxygen plasma and then transferred to a vacuum deposition machine. Using the ITO / Ag / ITO (reflective electrode) prepared in this way as an anode, Compound A doped with 3% NDP-9 (commercially available from Novaled) was vacuum-deposited on the ITO / Ag / ITO substrate to form a hole injection layer with a thickness of 100 Å, and Compound A was deposited on the hole injection layer with a thickness of 1350 Å to form a hole transport layer. Compound F-113 obtained in Synthesis Example 1 was deposited on the hole transport layer to a thickness of 285 Å to form a first hole transport auxiliary layer, and compound F-83 obtained in Synthesis Example 4 was deposited on the first hole transport auxiliary layer to a thickness of 50 Å to form a second hole transport auxiliary layer. On the second hole transport auxiliary layer, a light-emitting layer having a thickness of 380 Å was formed by vacuum deposition using 85 wt% of host H1 (40%) and host H2 (60%) as a host and doping with 15 wt% of PtGD as a dopant. Subsequently, compound C was deposited on the light-emitting layer to a thickness of 50 Å to form an electron transport auxiliary layer, and compound D and Liq were simultaneously vacuum-deposited at a 1:1 ratio to form an electron transport layer having a thickness of 310 Å. An organic light-emitting device was manufactured by sequentially vacuum-depositing Yb and AgMg on top of the electron transport layer to form a cathode.

[0980] It was fabricated with the structure of ITO / Ag / ITO / hole injection layer (compound A doped with 3% NDP-9, 100Å) / hole transport layer (compound A, 1350Å) / first hole transport auxiliary layer (compound F-113, 285Å) / second hole transport auxiliary layer (compound F-83, 50Å) / emission layer [Host (Host H1: Host H2 = 40 wt%: 60 wt%): PtGD = 85 wt%: 15 wt%] (380Å) / electron transport auxiliary layer (compound C, 50Å) / electron transport layer (compound D: Liq, 310Å) / Yb / AgMg.

[0995] (2) Measurement of luminance change according to voltage change

[0996] For the manufactured organic light-emitting device, the luminance was measured using a luminance meter (Minolta Cs-1000A) while increasing the voltage from 0 V to 10 V, and the results were obtained.

[0997] (3) Life span measurement

[0998] Luminance (cd / m 2 ) to 24000cd / m 2 The results were obtained by maintaining the current at 97% and measuring the time until the current efficiency (cd / A) decreased to 97%.

[0999] The life measurement values ​​of Examples 1 to 11 and Comparative Examples 2 to 4 were calculated as relative values ​​based on Comparative Example 1 and are listed in Table 1 below.
