Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to an organic light-emitting display and display device. Background Technology

[0002] Organic light-emitting diodes (OLEDs) are self-emissive elements that have an emissive layer between two electrodes. The OLED receives electrons and holes from a cathode (which acts as an electron injection electrode) and an anode (which acts as a hole injection electrode) and injects them into the emissive layer. The injected electrons and holes recombine to form excitons, and the OLED emits light when the excitons transition from the excited state to the ground state.

[0003] Currently, organic light-emitting displays (OLEDs) consist of a glass substrate and a cover. The glass substrate has anode circuitry, and organic and cathode materials are deposited by vapor deposition. All cover plates need to have a groove etched in them. A drying sheet is attached to the groove of the cover plate. The drying sheet absorbs water and oxygen inside the screen to prevent damage to the organic materials. In addition, the cover plate is bonded to the glass substrate with UV encapsulating adhesive to prevent moisture from entering.

[0004] However, before the customer assembles the product, the recessed section of the OLED display's encapsulation cover reflects light transmitted through the sides, creating bright lines. If the sides of the product are painted black, the recessed section of the encapsulation cover will no longer reflect light, and the bright lines will disappear. However, painting black is inefficient and costly, leading to customer dissatisfaction. Currently, the industry has not proposed an effective solution to this problem. Utility Model Content

[0005] Purpose of the utility model: To provide an organic light-emitting display and display device to at least solve one of the problems existing in the prior art.

[0006] Technical solution: An organic light-emitting display, comprising:

[0007] substrate;

[0008] Several insulating layers are disposed at intervals along a first direction on the substrate;

[0009] A packaged chip is disposed on the substrate near the side of the insulating layer;

[0010] A groove is formed along the first direction on the packaging sheet facing the substrate; and

[0011] A metallic virtual line is disposed on the insulating layer;

[0012] The metal virtual line is at least partially positioned above the groove wall to shield the groove cross-sectional area of ​​the package sheet.

[0013] Preferably, a sealant is provided between the substrate and the encapsulation sheet, and on the side near the outer edge.

[0014] Preferably, the position of the groove matches the position of the display area of ​​the substrate.

[0023] Beneficial effects: In this embodiment, by adding a metal virtual line, at least part of the metal virtual line is set directly above the groove wall to block the groove cross-sectional area of ​​the package sheet, thereby achieving the purpose of blocking the groove edge of the package sheet. This achieves the technical effects of eliminating bright lines, improving production efficiency, and reducing production costs. It also solves the technical problem that before the customer assembles the product, the groove cross-section of the organic light-emitting display package cover reflects the light transmitted from both sides, forming bright lines.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figure 1As shown, this application relates to an organic light-emitting display and a display device. The organic light-emitting display includes: a substrate 11; the substrate 11 refers to a carrier substrate 11, which can achieve a good load-bearing effect; further, the substrate 11 is a glass substrate 11, which can provide good physical properties.

[0032] A plurality of insulating layers 22 are disposed at intervals along a first direction on the substrate 11. By providing a plurality of insulating layers 22, electrical isolation can be achieved, short circuits in conductive parts can be prevented, and the substrate 11 can be protected from environmental influences. Herein, the first direction refers to the horizontal direction, which is also the X-axis direction in the two-coordinate system.

[0033] The encapsulation chip 110 is disposed on the substrate 11 near the insulating layer 22; it can provide mechanical protection, prevent external contamination, and improve device reliability.

[0034] A groove 88 is formed along the first direction on the package sheet 110 facing the substrate 11; it can ensure a good fit between the substrate 11 and the package sheet 110, thereby ensuring good electrical performance.

[0035] Specifically, the encapsulation die 110 needs to be etched with a groove 88 of a certain etching depth to match the display area (organic material area) of the glass substrate. The groove 88 and the display area of ​​the glass substrate maintain a certain safe distance to avoid damage to a limited extent.

[0036] It's important to know that the recessed cross-section of the package reflects light transmitted from both sides, making two bright lines clearly visible from the display surface. These bright lines can be blocked from view by obscuring them from the display surface.

[0037] A metallic dummy wire 330 is disposed on the insulating layer 22, enabling a good mating effect. It should be noted that the metallic dummy wire 330 is also a dummy wire.

[0038] Specifically, two openings need to be added to the cathode mask. The mask openings are located in the groove cross-section area of ​​the package 110, and the openings are kept at a safe distance from the openings in the display area. Dummy lines made of cathode material are added.

[0039] The cathode material is aluminum, which is opaque. When depositing aluminum cathode in the effective area, two dummy lines can be made to block the groove cross-section area of ​​the encapsulation sheet; at the same time, it does not affect the display area effect, and the manufacturing process is not increased.

[0040] Specifically, the metal virtual line 330 is at least partially disposed above the groove wall of the groove 88 to shield the groove cross-section 220 area of ​​the encapsulation sheet 110. By disposing the metal virtual line 330 above the groove wall of the groove 88 of the encapsulation sheet 110, the metal virtual line 330 can shield the groove wall, thereby preventing the appearance of bright lines.

[0041] It should be noted that the groove wall of groove 88 is also the cross-section of the groove.

[0042] Furthermore, the length of the metal virtual line 330 is greater than the cross-sectional area of ​​the groove 88. This ensures a good blocking effect, thereby preventing light leakage and improving product quality.

[0043] Cathode material is deposited over the recessed cross-sectional area of ​​the package 110 by vapor deposition. Adding cathode material requires adding two openings to the cathode mask. The mask openings are located in the recessed cross-sectional area of ​​the package, and the distance between the openings and the openings in the display area is kept at a safe distance.

[0044] As can be seen from the above description, this application achieves the following technical effects:

[0045] In this embodiment, a metal virtual line 330 is added. By placing the metal virtual line 330 at least partially above the groove wall of the groove 88, the cross-sectional area of ​​the groove 88 of the encapsulation sheet 110 is blocked. This achieves the purpose of blocking the edge of the groove 88 of the encapsulation sheet 110, thereby eliminating bright lines, improving production efficiency, and reducing production costs. This solves the technical problem that before the customer assembles the product, the cross-section of the groove 88 of the organic light-emitting display encapsulation sheet 110 reflects light transmitted from both sides, forming bright lines. If the two sides of the product are blackened with a black pen, the cross-section of the groove 88 of the encapsulation cover will not reflect light transmitted from both sides, and the bright lines will disappear. However, blackening is inefficient and costly, leading to customer dissatisfaction.

[0046] Furthermore, a sealant 99 is provided between the substrate 11 and the encapsulation sheet 110, near the outer edge. It is understood that the sealant 99 is an edge-sealing adhesive (EC edge-sealing adhesive), which can achieve a good sealing effect, thereby improving product lifespan; at the same time, it can also improve structural strength.

[0047] Furthermore, the position of the groove 88 matches the position of the display area of ​​the substrate 11. This ensures good optical performance, preventing the encapsulation sheet 110 from blocking light or affecting the display effect; the opening of the groove 88 can be used as a light transmission channel, improving overall optical performance; simultaneously, it ensures that the encapsulation sheet 110 does not interfere with the integrity of the display area of ​​the substrate 11, while also providing mechanical protection.

[0048] Furthermore, the recess 88 is equipped with an anti-reflective coating or a light-transmitting protective film, which can improve the brightness and clarity of the display area.

[0049] Furthermore, a conductive path or shielding layer can be embedded around the groove 88; this can shield electromagnetic interference without affecting the optical performance of the display area.

[0050] Furthermore, a gap is reserved between the groove 88 and the display area. It is understood that by reserving a gap, it is possible to avoid situations where manufacturing tolerances or assembly errors cause the groove 88 to partially press against the display area, affecting its function or causing mechanical damage.

[0051] At the same time, by reserving a gap, the fragile parts of the display area (such as the screen edge) are prevented from directly contacting the recess 88, reducing the risk of damage.

[0052] Preferably, the spacing can be 0.1-0.5mm. This ensures good assembly and electrical performance.

[0053] Furthermore, the substrate 11 is provided with a plurality of anode layers 44 spaced apart along the first direction and near the side of the package 110, and the plurality of anode layers 44 are respectively located between the insulating layers 22. It can be understood that by forming independent functional modules through spacing, electrical interference can be avoided, while improving the flexibility of wiring; of course, the specific layout can be adjusted according to functional requirements.

[0054] Each anode layer 44 is embedded between adjacent insulating layers 22 to ensure electrical isolation between anode layers 44 and avoid short circuit problems; at the same time, the insulating layer 22 not only has electrical isolation function, but may also provide mechanical protection and environmental barrier (such as moisture protection, oxidation protection, etc.).

[0055] Specifically, the anode layer 44 is typically a conductive layer used to supply current to electronic devices and inject charge into adjacent organic material layers. It is usually made of a transparent conductive material (such as ITO: indium tin oxide), which has high conductivity and good optical transmittance, making it particularly suitable for light-emitting devices.

[0056] Furthermore, a first organic material layer 55 is disposed on the anode layer 44, and a first cathode layer 66 is disposed on the first organic material layer 55. It is understood that this achieves a good layout effect and also ensures good fit between components.

[0057] Specifically, the first organic material layer 55 is an organic functional layer disposed on the anode layer 44, which usually plays the role of photoelectric conversion or charge transport.

[0058] Light-emitting layer: If used in OLEDs, this layer is responsible for emitting light and contains light-emitting materials (such as europium, platinum complexes, etc.).

[0059] Charge transport layer: In photovoltaic devices or other applications, the organic material layer is mainly used to conduct positive or negative charges.

[0060] The choice of organic material layer affects performance such as luminescence efficiency, carrier transport speed, and lifetime.

[0061] The first cathode layer 66 is a conductive layer covering the first organic material layer 55, used for injecting or collecting electrons, and is usually made of a low work function metal material (such as aluminum, calcium or aluminum / calcium composite layer); its function is to form a complete electric field, which together with the anode layer 44 drives the photoelectric effect of the organic layer.

[0062] Furthermore, a plurality of isolation pillars 33 are respectively disposed on the insulating layer 22 and above the groove 88, and a second organic material layer 440 and a second cathode layer 550 are sequentially disposed on the isolation pillars 33. It can be understood that the isolation pillars 33 are small columnar structures disposed on the insulating layer 22 and above the groove 88. Physical support: They provide support and isolation between layers, ensuring the stability of the structure; Insulation effect: They block current and prevent interlayer short circuits.

[0063] Furthermore, several drying layers 77 are spaced apart within the groove 88. This allows for effective drying, absorbing moisture within the groove 88 and reducing the impact of humidity on device performance.

[0064] Furthermore, all of the encapsulation sheets 110 are made of glass. This, understandably, provides excellent physical properties.

[0065] This application also relates to a display device, including the organic light-emitting display as described above. The display device using the organic light-emitting display provided in this embodiment has the same basic principle and technical effects as the above embodiment. For any parts not mentioned in this embodiment, please refer to the corresponding content above.

[0066] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
