Description

[0001] This application claims priority to and the benefit of Korean Patent Application No. 10-2018-0008951 filed on January 24, 2018, in the Korean Intellectual Property Office, and Korean Patent Application No. 10-2018-0008952 filed on January 24, 2018, in the Korean Intellectual Property Office, the entire contents of each of which are incorporated herein by reference. Technical Field

[0002] One or more embodiments relate to a heterocyclic compound, an electronic device including an organic light emitting device, and a method of manufacturing the electronic device. Background Art

[0003] The electronic device may include an organic light-emitting device, which includes a hole injection electrode, an electron injection electrode, and an organic emission layer located between the hole injection electrode and the electron injection electrode. Compared with other devices in the art, the organic light-emitting device is a self-emitting device with wide viewing angle, high contrast, short response time, and excellent characteristics in terms of brightness, driving voltage and response speed. For example, an organic light-emitting display device, which is a class (or a type) of electronic devices including an organic light-emitting device, is a self-emitting device in which holes injected from the hole injection electrode and electrons injected from the electron injection electrode recombine in the organic emission layer to generate excitons. These excitons transition (e.g., transition or relaxation) from an excited state to a ground state, thereby generating light.

[0004] Since an organic light emitting display device as a self-emitting display device does not require a separate light source, the organic light emitting display device can be driven at a low voltage, can be constructed to be lightweight and thin, and can have excellent characteristics in terms of viewing angle, contrast, and response time. Therefore, such an organic light emitting display device has applications ranging from personal portable devices such as MP3 players and mobile phones to televisions (TVs), but is not limited thereto.

[0005] In addition, as the outdoor use of information devices such as electronic devices including organic light-emitting devices increases, electronic devices including organic light-emitting devices are increasingly exposed to sunlight. In addition, in the process of manufacturing organic light-emitting devices, there are many cases where operations involving ultraviolet irradiation are required. Therefore, if ultraviolet rays are freely transmitted to the inside of the organic light-emitting device, the emission layer including organic materials, etc., may be seriously damaged. Summary of the invention

[0006] During the manufacturing process of electronic devices such as organic light emitting displays, when ultraviolet rays or the like are introduced into the device from outside the device or penetrate into the device from outside the device, an emission layer including organic materials, an insulating film, etc. may be severely damaged.

[0007] Aspects of embodiments of the present disclosure provide an electronic device capable of reducing the amount of ultraviolet rays transmitted into the electronic device. However, these aspects of the embodiments are illustrative, and the scope of the present disclosure is not limited thereto.

[0008] Additional aspects of the embodiments will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the presented embodiments.

[0221] In one or more embodiments, at least one organic film may include a first organic film, a second organic film, and a third organic film, at least one inorganic film may include a first inorganic film and a second inorganic film, and the first organic film, the first inorganic film, the second organic film, the second inorganic film, and the third organic film may be sequentially stacked in the order stated from the organic light emitting device 200, but the embodiments of the present disclosure are not limited thereto. The number of organic films and inorganic films and the stacking order of inorganic films and organic films may be appropriately modified according to design.

[0222] The organic light emitting display device 10 may include a plurality of organic light emitting devices 200. In one embodiment, the organic light emitting display device 10 may include: a substrate; an organic emission unit including a plurality of organic light emitting devices 200 located on the substrate; and a thin film encapsulation member 300 sealing the organic emission unit, wherein the thin film encapsulation member 300 includes a UV stabilizing mixture. The UV stabilizing mixture is the same as described above.

[0223] For example, the thin film encapsulation 300 may include a UV stabilizing mixture, and in addition to the UV stabilizing mixture, the thin film encapsulation 300 may further include a matrix resin. The matrix resin is the same as described above.

[0224] In one embodiment, the thin film encapsulation 300 may include metal, metal halide, metal nitride, metal oxide, metal oxynitride, silicon nitride, silicon oxide, and silicon oxynitride in addition to the UV stabilizing compound.

[0225] In one embodiment, the thin film package 300 may include at least one organic film and at least one inorganic film, and the at least one organic film may include a UV absorber. The at least one organic film and the at least one inorganic film are the same as described above.

[0226] Another aspect of the embodiment provides a method of manufacturing an electronic device, the method comprising:

[0227] forming an organic light emitting device on a substrate; and

[0228] forming a thin film package sealing the organic light emitting device on the substrate,

[0229] The formation of the thin film encapsulation member includes providing a thin film encapsulation composition for sealing the organic light-emitting device and curing the thin film encapsulation composition.

[0230] The thin film encapsulation composition comprises a UV stable mixture,

[0231] The UV stabilizing mixture includes a UV absorber and a free radical scavenger.

[0232] The thin film encapsulant, UV stabilizing mixture, UV absorber and free radical scavenger are the same as those described above. When the electronic device is manufactured according to the above method, external UV rays are blocked from reaching the organic light emitting device, thereby preventing damage to the organic light emitting device when it is continuously exposed to UV rays (or reducing the possibility or degree of such damage), and improving the durability of the organic light emitting device and the electronic device including the organic light emitting device.

[0233] In one embodiment, the thin film encapsulation composition may further include a matrix resin monomer and a photopolymerization initiator.

[0234] The matrix resin monomer may be photopolymerized to form the matrix resin included in the thin film encapsulation. For example, the matrix resin monomer may be photopolymerized by a photopolymerization initiator to form the matrix resin included in the thin film encapsulation. The photopolymerization initiator is the same as described above.

[0235] Figure 2 is a schematic cross-sectional view of an organic light emitting display device as one of the electronic devices according to an embodiment.

[0236] Reference Figure 2, forming a backplane. The backplane may be understood to include at least: a substrate 100; a plurality of first electrodes 210R, 210G, and 210B located on the substrate 100; and a pixel defining film 180 formed to expose at least a portion of the central portion including the first electrodes 210R, 210G, and 210B. The pixel defining film 180 may have a shape protruding from the first electrodes 210R, 210G, and 210B in the +z direction relative to the substrate 100.

[0237] The first electrode 210R, 210G and 210B can be understood as pixel electrodes. The pixel electrode 210R, the pixel electrode 210G and the pixel electrode 210B among the pixel electrodes can be understood as the first pixel electrode, the second pixel electrode and the third pixel electrode respectively. This is because the intermediate layer formed on the first pixel electrode to the third pixel electrode can be different. For convenience, the terms "pixel electrode 210R", "pixel electrode 210G" and "pixel electrode 210B" are used to replace the first pixel electrode, the second pixel electrode and the third pixel electrode. The pixel electrode is the same as described in conjunction with the first electrode.

[0238] The pixel defining film 180 may have an opening corresponding to each sub-pixel, that is, an opening exposing the central portion of the pixel electrodes 210R, 210G, and 210B or the entire pixel electrodes 210R, 210G, and 210B, thereby defining the pixel. In addition, the pixel defining film 180 may increase the distance between the end of the pixel electrodes 210R, 210G, and 210B and the second electrode 230 located on the pixel electrodes 210R, 210G, and 210B, thereby preventing arcs, etc. from being generated at the end of the pixel electrodes 210R, 210G, and 210B (or reducing the possibility or degree of such arcs).

[0239] If necessary, the back panel may also include other various suitable components. Figure 2 As shown in , the thin film transistor TFT or the capacitor Cap may be formed on the substrate 100. The backplane may include the following components: such as a buffer layer 110 for preventing impurities from penetrating the semiconductor layer of the thin film transistor TFT (or reducing the possibility or amount of impurities penetrating the semiconductor layer of the thin film transistor TFT); a gate insulating film 130 for insulating the semiconductor layer of the thin film transistor TFT from the gate electrode; an interlayer insulating film 150 for insulating the source electrode / drain electrode of the thin film transistor TFT from the gate electrode; and a planarizing film 170 covering the thin film transistor TFT and having a substantially flat upper surface.

[0240] After forming the backplane, the intermediate layers 220R, 220G, and 220B are formed. The intermediate layers 220R, 220G, and 220B may have a multilayer structure including an emission layer. In this case, unlike those shown, some of the intermediate layers 220R, 220G, and 220B may be a common layer substantially corresponding to the entire surface of the substrate 100, and some of the intermediate layers 220R, 220G, and 220B may be pattern layers patterned corresponding to the pixel electrodes 210R, 210G, and 210B.

[0241] After the intermediate layers 220R, 220G, and 220B are formed, the second electrode 230 is formed on the intermediate layers 220R, 220G, and 220B.

[0242] After forming the second electrode 230 , the thin film encapsulation 300 is formed to protect the organic light emitting device 200 including the pixel electrodes 210R, 210G, and 210B, the intermediate layers 220R, 220G, and 220B, and the second electrode 230 from impurities such as external oxygen or moisture.

[0243] The thin film encapsulation 300 may extend to cover not only the upper surface of the organic light-emitting device 200 but also the side surfaces of the organic light-emitting device 200 and the contact portion of the substrate 100. Therefore, it is possible to effectively prevent external oxygen and moisture from penetrating the organic light-emitting device 200 (or reduce the possibility or amount of external oxygen and moisture penetrating the organic light-emitting device 200).

[0244] The thin film encapsulation 300 includes a UV stabilizing mixture.

[0420] In addition, as described above, another aspect of the embodiment provides an electronic device, the electronic device comprising:

[0421] substrate;

[0422] an organic light emitting device disposed on a substrate; and

[0423] Thin film encapsulation, sealing organic light emitting devices,

[0424] Wherein, the thin film encapsulation comprises a heterocyclic compound.

[0425] The electronic device in which the thin film encapsulation includes the heterocyclic compound may be, for example, an organic light emitting display device, but the embodiments of the present disclosure are not limited to the organic light emitting display device. Figure 1-Figure 2 The description is provided to understand the description of the electronic device and the organic light emitting display device. In this case, for example, a heterocyclic compound may be used instead of the UV stabilizing compound.

[0426] In one embodiment, the thin film encapsulation 300 may include at least two types (or species) of heterocyclic compounds.

[0427] For example, the thin film encapsulation may include a first heterocyclic compound represented by Formula B1 and a second heterocyclic compound represented by Formula B1, and a wavelength range of light absorbed by the first heterocyclic compound may be different from a wavelength range of light absorbed by the second heterocyclic compound.

[0428] In one embodiment, when the thin film encapsulation includes at least two types (or kinds) of heterocyclic compounds, the average transmittance within the wavelength range of about 380nm to about 400nm can be about 10% or less, and the average transmittance within the wavelength range of about 400nm to about 430nm can be about 60% or greater.

[0429] The heterocyclic compound can absorb ultraviolet rays and prevent ultraviolet rays from penetrating the organic light-emitting device 200 (or reduce the possibility or amount of ultraviolet rays penetrating the organic light-emitting device 200). Therefore, the organic light-emitting display device 10 in which the thin film encapsulation 300 includes the heterocyclic compound can prevent the emission layer, the insulating film, etc. including the organic material from being damaged by ultraviolet rays (or can reduce the possibility or degree of such damage).

[0430] In one embodiment, the thin film package 300 may include at least one organic film, the at least one organic film may include a first organic film, and the first organic film may include a heterocyclic compound.

[0431] In one embodiment, the thin film encapsulation (eg, the first organic film) including the heterocyclic compound may have a transmittance of about 10% or less (eg, 8%) with respect to light having a wavelength of about 400 nm to about 410 nm (eg, 405 nm).

[0436] In one or more embodiments, when the first organic film is at about 52,000 Wh / m 2 When the exposure amount is exposed to light having a wavelength range of about 380 nm to about 410 nm and a maximum emission wavelength of about 405 nm, a change in transmittance with respect to a wavelength range of about 400 nm to about 410 nm may be less than about 5%.

[0437] In one or more embodiments, when the first organic film is at about 52,000 Wh / m 2 When the exposure amount is exposed to light having a wavelength range of about 380 nm to about 410 nm and a maximum emission wavelength of about 405 nm, a change in transmittance with respect to a wavelength range of about 400 nm to about 405 nm may be less than about 3%.

[0438] In one or more embodiments, when the first organic film is at about 52,000 Wh / m 2 When the exposure amount is exposed to light having a wavelength range of about 380 nm to about 410 nm and a maximum emission wavelength range of about 405 nm, a change in transmittance with respect to a wavelength range of about 400 nm to about 405 nm may be less than about 1%.

[0439] The change in transmittance with respect to the above wavelength range may be measured by, for example, exposing the first organic film through the use of an LED light emitting light in a wavelength range of about 380 nm to about 410 nm and having a maximum emission wavelength of about 405 nm.

[0440] In one embodiment, the first organic film may have a thickness in a range of about 10 nm to about 20 μm, for example, in a range of about 10 nm to about 10 μm.

[0441] In one embodiment, the amount of the heterocyclic compound may be in a range of about 3 parts by weight to about 10 parts by weight based on 100 parts by weight of the first organic film. By controlling the amount of the heterocyclic compound in the first organic film, the maximum absorption wavelength of the first organic film may be finely adjusted, and the UV absorption spectrum may be controlled.

[0442] For example, at least one organic film may be composed of a heterocyclic compound.

[0443] In one or more embodiments, in addition to the heterocyclic compound, at least one organic film may further include a matrix resin, and the heterocyclic compound may be dispersed in the matrix resin. In this case, the heterocyclic compound may be simply dispersed in the matrix resin, or the heterocyclic compound may be cross-linked with the matrix resin.

[0445] The matrix resin may include at least one of an acryl-based resin, a methacryl-based resin, an isoprene-based resin, a vinyl-based resin, an epoxy-based resin, a urethane-based resin, a cellulose resin, a perylene-based resin, an imide-based resin, and a silicone-based resin.

[0446] In one or more embodiments, at least one organic film may further include a photopolymerization initiator in addition to the heterocyclic compound. The photopolymerization initiator is the same as described above.

[0447] In one or more embodiments, at least one organic film may further include a matrix resin and a photopolymerization initiator in addition to the heterocyclic compound.

[0448] Another aspect of the embodiment provides a method of manufacturing an electronic device, the method comprising:

[0449] forming an organic light emitting device on a substrate; and

[0450] forming a thin film package sealing the organic light emitting device on the substrate,

[0451] The formation of the thin film encapsulation comprises providing a thin film encapsulation composition for sealing the organic light-emitting device and curing the thin film encapsulation composition.

[0452] The thin film encapsulation composition includes a heterocyclic compound.

[0453] The thin film encapsulation member, the heterocyclic compound and the thin film encapsulation composition are the same as those described above. When an electronic device is manufactured according to the above method, external UV rays are blocked from reaching the organic light-emitting device, thereby preventing damage to the organic light-emitting device when it is continuously exposed to UV rays (or reducing the possibility or degree of such damage), and improving the durability of the organic light-emitting device and the electronic device including the organic light-emitting device.

[0481] Example

[0482] Example 1-1

[0483] An electronic device including a thin film encapsulation sealing an organic light emitting device on a substrate is manufactured. The thin film encapsulation is formed by using a thin film encapsulation composition including benzophenone as a UV absorber and 1,2-naphthalene diol as a radical scavenger.

[0484] Comparison Example 1-1

[0485] A thin film encapsulation member sealing an organic light emitting device on a substrate was formed by using the thin film encapsulation composition in substantially the same manner as Example 1-1, except that benzophenone was used instead of the UV absorber and the radical scavenger was not used.

[0486] Evaluation Example 1

[0487] The initial transmittance of the thin film package of each of the electronic devices manufactured according to Example 1-1 and Comparative Example 1-1 was measured, and the transmittance at 52,000 Wh / m 2The transmittance after exposure for 30 minutes ("transmittance after exposure") is shown in Figure 3 middle.

[0488] Reference Figure 3 , in the electronic device according to Example 1-1, the time required for the transmittance of the thin film encapsulation to increase is longer than that of Comparative Example 1-1, and therefore, it is confirmed that the light curing resistance is excellent. For example, with respect to a wavelength of 405nm, since the electronic device of Comparative Example 1-1 has an initial transmittance of approximately 2% and a transmittance after exposure of approximately 8%, the change in transmittance (the value obtained by subtracting the initial transmittance from the transmittance after exposure) is approximately 6%, and the transmittance is increased fourfold by 30 minutes of exposure. On the contrary, with respect to a wavelength of 405nm, since the electronic device of Example 1-1 has an initial transmittance of approximately 3% and a transmittance after exposure of approximately 6%, the transmittance change is small compared to Comparative Example 1-1.

[0489] Therefore, an organic light emitting display device including a UV stabilizing mixture in a thin film package can prevent an emission layer including an organic material, an insulating film, and the like from being damaged by ultraviolet rays (or can reduce the possibility or degree of such damage).
