Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0136217 filed in the Korean Intellectual Property Office on October 12, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The embodiments relate to a light emitting device, an electronic device including the light emitting device, and an electronic equipment including the light emitting device. Background Art

[0004] The light-emitting device is a self-emissive device that has wide viewing angle, high contrast, short response time, and excellent characteristics in terms of brightness, driving voltage, and response speed.

[0005] The light-emitting device may have a structure in which a first electrode is arranged on a substrate, and a hole transport region, an emission layer, an electron transport region, and a second electrode may be arranged in sequence on the first electrode. Holes injected from the first electrode move toward the emission layer through the hole transport region, and electrons injected from the second electrode move toward the emission layer through the electron transport region. Carriers, such as holes and electrons, recombine in the emission layer to generate excitons. When the excitons transition from an excited state to a ground state, light is generated.

[0006] It should be understood that this background technology section is intended to provide, in part, a useful background for understanding the technology. However, this background technology section may also include ideas, concepts or cognitions that were not known or understood by a person skilled in the relevant art before the corresponding effective filing date of the subject matter disclosed herein.

[0076] The present disclosure will now be described more fully below with reference to the attached drawings in which embodiments are shown. However, the present disclosure may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art.

[0077] In the drawings, the size (eg, thickness), ratio, and dimensions of elements may be exaggerated for ease of description and for clarity. Like reference numerals and reference characters refer to like elements throughout.

[0078] In the specification, it will be understood that when an element (or region, layer, component, etc.) is referred to as being "on", "connected to" or "coupled to" another element (or region, layer, component, etc.), it may be directly on, directly connected to or directly coupled to the other element (or region, layer, component, etc.), or one or more intervening elements (or regions, layers, components, etc.) may exist between them. In a similar sense, when an element (or region, layer, component, etc.) is described as "covering" another element (or region, layer, component, etc.), it may directly cover the other element (or region, layer, component, etc.), or one or more intervening elements (or regions, layers, components, etc.) may exist between them.

[0079] In the specification, when an element is "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements. For example, "directly on" may mean that two layers or two elements are disposed without additional elements such as adhesive elements between them.

[0080] In the specification, expressions used in the singular such as “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0081] In the specification, the term "and / or" includes any and all combinations of one or more related listed items. For example, "A and / or B" can be understood to mean "A, B, or A and B". The terms "and" and "or" can be used in a connecting sense or a separating sense and can be understood to be equivalent to "and / or".

[0082] In the specification and claims, for the purposes of its meaning and interpretation, the term "at least one of" is intended to include the meaning of "at least one selected from the group consisting of..." For example, "at least one of A, B, and C" may be understood to mean only A, only B, only C, or any combination of two or more of A, B, and C, such as ABC, ACC, BC, or CC. When following a list of elements, the term "at least one of" modifies the entire list of elements and does not modify the individual elements of the list.

[0083] It will be understood that although the terms first, second, etc. may be used to describe various elements in this article, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Therefore, without departing from the teachings of the present disclosure, the first element may be referred to as the second element. Similarly, without departing from the scope of the present disclosure, the second element may be referred to as the first element.

[0084] For ease of description, spatially relative terms such as "below," "under," "down," "above," or "on" may be used herein to describe the relationship between one element or component and another element or component as illustrated in the accompanying drawings. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. For example, in the case where the device illustrated in the accompanying drawings is turned over, a device that is "below" or "below" another device may be placed "above" the other device. Accordingly, the illustrative term "below" may include both a lower position and an upper position. The device may also be oriented in other directions, and therefore the spatially relative terms may be interpreted differently depending on the orientation.

The first capping layer and the second capping layer may be as further described herein.

[0179] In an embodiment, the light emitting device may include:

[0180] a first capping layer, external to the first electrode, and comprising the first compound, the second compound, the transition metal-containing compound, the boron-containing compound, or any combination thereof;

[0182] A first capping layer and a second capping layer.

[0183] As used herein, the expression “(the interlayer and / or the capping layer) includes a first compound (or a second compound, a transition metal-containing compound, a boron-containing compound, or any combination thereof)” may be interpreted as “(the interlayer and / or the capping layer) may include one type of first compound (or second compound, transition metal-containing compound, boron-containing compound, or any combination thereof) or two or more different types of first compounds (or second compounds, transition metal-containing compounds, boron-containing compounds, or any combination thereof)”.

[0184] For example, the interlayer and / or the capping layer may include compound HTH1 alone as the first compound (or the second compound, the transition metal-containing compound, the boron-containing compound, or any combination thereof). In this regard, compound HTH1 may be present in the emission layer of the light-emitting device. In an embodiment, the interlayer may include compound HTH1 and compound HTH2 as the first compound (or the second compound, the transition metal-containing compound, the boron-containing compound, or any combination thereof). In this regard, compound HTH1 and compound HTH2 may be present in the same layer (for example, both compound HTH1 and compound HTH2 may be present in the emission layer), or may be present in different layers (for example, compound HTH1 may be present in the emission layer, and compound HTH2 may be present in the electron transport region).

[0185] As used herein, the term "interlayer" refers to a single layer and / or multiple layers between a first electrode and a second electrode of a light emitting device.

[0186] According to an embodiment, an electronic device may include the above-mentioned light emitting device. The electronic device may further include a thin film transistor. In an embodiment, the electronic device may further include: a thin film transistor including a source electrode and a drain electrode, and the first electrode of the light emitting device may be electrically connected to at least one of the source electrode and the drain electrode. In an embodiment, the electronic device may further include a color filter, a color conversion layer, a touch screen layer, a polarization layer, or any combination thereof. The electronic device may be as described herein.

[0187] According to an embodiment, electronic equipment may include the above-mentioned light emitting device.

[0188] In embodiments, the electronic device may be a flat panel display, a curved display, a computer monitor, a medical monitor, a television, a billboard, an indoor light, an outdoor light, a signal light, a head-up display, a fully transparent display, a partially transparent display, a flexible display, a rollable display, a foldable display, a stretchable display, a laser printer, a phone, a mobile phone, a tablet computer, a phablet, a personal digital assistant (PDA), a wearable device, a laptop computer, a digital camera, a camcorder, a viewfinder, a microdisplay, a three-dimensional (3D) display, a virtual reality display, an augmented reality display, a vehicle, a video wall with multiple displays stitched together, a theater screen, a stadium screen, a light therapy device, or a sign.

[0189] The moiety represented by Formula 1, for example, a carbazole moiety, may have a chemically stable and rigid structure, have a high T1 energy level, and have excellent charge transport capability. Therefore, if the moiety represented by Formula 1 is introduced into a host in an emission layer (for example, a first compound and / or a second compound as described herein), it may be suitable for achieving charge balance, and thus, device lifetime degradation associated with charge imbalance, for example, triplet polaron annihilation, may be prevented.

[0190] In an embodiment, if the portion represented by Formula 1 is included in both the host material (e.g., the first compound and / or the second compound) and the dopant (or emitter) material (e.g., a transition metal compound and / or a boron compound) of the emission layer, it may facilitate HOMO energy level matching between the host material and the dopant (or emitter) material.

[0191] In an embodiment, the moiety represented by Formula 1 can strengthen the rigidity of the ligand in a metal complex having a square planar structure, such as a tetracoordinate platinum complex, thereby reducing molecular vibration. In order to increase the photoluminescence quantum yield (PLQY) by making full use of triplet excitons having a long residence time in an excited state, it is important to reduce non-radiative processes such as molecular vibration, and if the moiety represented by Formula 1 is introduced into a metal complex having a square planar structure, the non-radiative process can be reduced, thereby providing an effect of increasing the PLQY.

[0192] Light-emitting devices, such as blue thermally activated delayed fluorescence (TADF) devices using triplet excitons, require the use of a host material having a wide band gap and a high T1 energy level, compared to fluorescent devices using singlet excitons, and the portion represented by Formula 1 may allow the host material to have a wide band gap and a high T1 energy level. The host material including the portion represented by Formula 1 has a deep HOMO energy level, and therefore, if the dopant (or emitter) material has a shallow HOMO energy level compared to the host material including the portion represented by Formula 1, the dopant (or emitter) may capture holes and directly perform charge recombination, thereby promoting capture-assisted recombination (TAR) of generated excitons. This increases the concentration of triplet excitons on the dopant (or emitter), resulting in a reduction in the luminous efficiency and device life of the device. Therefore, if a host material including a portion represented by Formula 1 is used, a deep HOMO energy level of the dopant (or emitter) is required. In this regard, if the dopant (or emitter) material (e.g., a boron-containing compound) includes the portion represented by Formula 1, the HOMO energy level of the dopant (or emitter) material (e.g., a boron-containing compound) can match the HOMO energy level of the host material (e.g., the first compound and / or the second compound), and thus, degradation of luminous efficiency and device life can be prevented.

[0193] In an embodiment, if a dopant (or emitter) material (e.g., a boron-containing compound) includes a portion represented by Formula 1, the charge transfer (CT) characteristics of the molecule can be increased, thereby providing an effect of accelerating reverse intersystem crossing (RISC), electrons can be supplied to electron-deficient boron atoms, thereby providing an effect of chemically stabilizing boron, and the oscillator strength can be increased, resulting in excellent luminous efficiency. In an embodiment, intramolecular expansion can be increased, resulting in a core protection effect.

[0194] In an embodiment, the moiety represented by Formula 1 itself may have a HOMO / LUMO form similar to a multi-resonance in which large electron density and small electron density alternate between adjacent atoms. If the moiety represented by Formula 1 is introduced, the unique HOMO / LUMO form of the moiety represented by Formula 1 and the HOMO / LUMO form of the multi-resonance core of the boron-containing compound are made good, the overall multi-resonance characteristics of the molecule can be enhanced, and thus ΔE can be reduced. ST , and can improve RISC characteristics.

[0195] In a light-emitting device using triplet excitons and auxiliary dopants, in order to increase the luminous efficiency and device life of the light-emitting device, it is important to prevent Dexter energy transfer (DET) between the auxiliary dopant (e.g., transition metal compound) and the dopant (or emitter) (e.g., boron compound). DET is a near-field transfer in the form of energy exchange, which mainly occurs in an environment where the orbits overlap. In order to prevent DET, the physical distance between the auxiliary dopant and the dopant (or emitter) must be long. If the physical distance is close, a substituent that prevents orbital overlap is required. The portion represented by Formula 2 may be a substituent that is almost non-electrically active (or has low electrical activity) and has a chemically stable structure. If introduced into each of the auxiliary dopant and the dopant (or emitter), the physical distance between the auxiliary dopant and the dopant (or emitter) is increased, and orbital overlap can be prevented.

[0196] The auxiliary dopant (e.g., transition metal compound) with a square planar structure has high planarity and forms an excited molecule or excited complex with an electron transport (ET) material containing triazine, etc., and therefore, the side effect of broadening the emission peak may occur. Due to the characteristics of the core with high planarity, the boron-containing dopant (or emitter) (e.g., boron-containing compound) is also prone to the same problem. For example, the broadening of the emission peak in the top emission OLED using a resonance method may cause the problem of increasing the part of the transmission spectrum that does not pass through the resonance structure, which leads to a decrease in luminous efficiency and a decrease in device life due to an increase in applied current. The auxiliary dopant and dopant having a part represented by Formula 2 can prevent the degradation of the luminous properties (e.g., luminous efficiency) and device life of the light-emitting device by suppressing such intermolecular interactions.

[0519] The delayed fluorescent material included in the emission layer may serve as a host or a dopant depending on the types of other materials included in the emission layer.

[0520] In an embodiment, the difference between the triplet energy level (eV) of the delayed fluorescent material and the singlet energy level (eV) of the delayed fluorescent material may be in the range of about 0 eV to about 0.5 eV. When the difference between the triplet energy level (eV) of the delayed fluorescent material and the singlet energy level (eV) of the delayed fluorescent material is in the above range, up-conversion of the delayed fluorescent material from the triplet state to the singlet state may effectively occur, and thus, the light emitting device 10 may have improved luminous efficiency.

[0539] In an embodiment, the quantum dot may have a single structure in which the concentration of each element in the quantum dot is uniform, or the quantum dot may have a core-shell structure. For example, in the case where the quantum dot may have a core-shell structure, the material included in the core and the material included in the shell may be different from each other.

[0540] The shell of the quantum dot can be used as a protective layer to prevent chemical denaturation of the core to maintain semiconductor properties, and / or can be used as a charging layer to impart electrophoretic properties to the quantum dot.

For example, the quantum dot may have a FWHM of an emission wavelength spectrum equal to or less than about 40 nm.

When the FWHM of the quantum dot is within any of the above ranges, color purity and / or color reproducibility may be improved.

[0545] By adjusting the size of the quantum dots, the energy band gap can be adjusted, and thus light of various wavelengths can be obtained from the quantum dot emission layer.
