Description

Technical Field

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

[0002] Organic light-emitting display (OLED) technology is widely used in the display field, but its heat dissipation problem remains a key factor limiting performance and lifespan. Since OLED panels generate a lot of heat during operation, poor heat dissipation can easily lead to brightness decay, color distortion and shortened lifespan. Therefore, optimizing the heat dissipation structure of OLED devices and improving thermal management efficiency are important research directions for improving their performance and extending their lifespan.

[0003] However, in practical use, the following shortcomings still exist. For example, existing organic light-emitting display devices cannot achieve efficient and stable light emission and rapid heat dissipation. Excessive heat will increase the energy loss inside the organic materials, reduce the carrier recombination efficiency, and cause a significant decrease in light emission efficiency. High temperature may increase the molecular thermal motion of organic materials, interfere with the transmission of charge carriers, and cause the pixel response speed to slow down, affecting the clarity of dynamic images. The light-emitting layer and electron transport layer of OLED are mainly composed of organic materials. High temperature will accelerate the decomposition of materials, the destruction of crystal structure, or the reaction with electrodes, leading to the failure of the light-emitting layer. Overheating will cause the electrode resistance to increase, the mobility to decrease, and even electromigration to occur, causing short circuits or open circuits.

[0004] Therefore, this utility model proposes an organic light-emitting display device with optimized heat dissipation structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose an organic light-emitting display device with optimized heat dissipation structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an organic light-emitting display device with optimized heat dissipation structure, including a mounting shell, and further comprising:

[0007] An organic light-emitting display component includes an ultra-thin glass layer disposed on a mounting housing, a siloxane buffer layer disposed on the ultra-thin glass layer, a flexible polymer film layer disposed on the siloxane buffer layer, an anode layer disposed on the flexible polymer film layer, a hole injection material layer disposed on the anode layer, a cathode layer disposed on the hole injection material layer, an inorganic film layer disposed on the cathode layer, and a transparent organic gel layer disposed on the inorganic film layer.

[0008] A heat dissipation assembly includes a copper pillar connected to the bottom of an ultra-thin glass layer. A heat-conducting plate is disposed inside the mounting housing near the copper pillar. Heat dissipation fins are connected to the bottom of the heat-conducting plate and disposed inside the mounting housing. A fan is installed on one side of the mounting housing, and an air outlet is provided on the side of the mounting housing away from the fan.

[0009] Furthermore, a first magnetic block is connected to the bottom of the ultra-thin glass layer, and a second magnetic block is connected to the side of the mounting shell near the first magnetic block, with the first magnetic block disposed on the second magnetic block.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the first magnetic block is connected to the bottom of the ultra-thin glass layer, and the second magnetic block is fixed in the corresponding position inside the mounting shell. When the device is assembled, relying on the property of opposite magnetic poles attracting each other, the first magnetic block is attracted to the second magnetic block, which quickly realizes the initial positioning and connection of the organic light-emitting display component and the mounting shell, providing a foundation for subsequent stable installation, while facilitating disassembly and maintenance.

[0011] Furthermore, the mounting housing is provided with a snap-fit ​​assembly, which includes a snap-fit ​​base connected to one side of the bottom of the ultra-thin glass layer, and the snap-fit ​​base has a snap-fit ​​groove.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the card holder is fixed on one side of the bottom of the ultra-thin glass layer, and the card slot opened on it serves as a connection interface.

[0013] Furthermore, a retaining plate is slidably connected inside the mounting housing, and a telescopic spring is provided on the retaining plate.

[0014] The beneficial effects of adopting the above-mentioned further solution are: during the installation process, the slot provides an embedding space for the card plate, and the two work together to achieve a snap-fit, further fixing the organic light-emitting display component to the mounting shell, enhancing structural stability, and ensuring reliable installation of the organic light-emitting display component in the device.

[0015] Furthermore, one end of the telescopic spring is connected inside the mounting housing, and the other end of the telescopic spring is connected to the card plate.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the card plate can slide inside the mounting shell, and one end of the telescopic spring is connected to the mounting shell and the other end is connected to the card plate.

[0017] Furthermore, the card plate is disposed within the card slot.

[0018] The beneficial effects of adopting the above-mentioned further solution are as follows: During installation, first press the card plate, the telescopic spring stretches, then place the organic light-emitting display component into the mounting shell. After releasing the card plate, the telescopic spring rebounds, tightly locking the card plate into the slot. During disassembly, press the card plate to detach it from the slot, thus separating the component.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, when the organic light-emitting display device is working, current flows into the organic light-emitting display component through the anode layer, and the hole injection material layer assists in hole injection. The electrons injected into the cathode layer recombine and emit light internally. The light passes through the flexible polymer film layer and other materials to emit light outward. The heat generated during operation is first conducted through the ultra-thin glass layer to the bottom copper pillar, and then transferred to the heat dissipation fins through the heat conduction plate to increase the heat dissipation area. At the same time, the fan operates, blowing cold air into the mounting shell, which flows through the heat dissipation fins and carries away the heat. The hot air is discharged from the air outlet, ensuring that the device operates stably at a suitable temperature. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-4 As shown, this embodiment provides a technical solution: an organic light-emitting display device with optimized heat dissipation structure, including a mounting shell 1, and further comprising:

[0033] Organic light-emitting display component 2 includes an ultra-thin glass layer 21 disposed on a mounting shell 1, a siloxane buffer layer 22 disposed on the ultra-thin glass layer 21, a flexible polymer film layer 23 disposed on the siloxane buffer layer 22, an anode layer 24 disposed on the flexible polymer film layer 23, a hole injection material layer 25 disposed on the anode layer 24, a cathode layer 26 disposed on the hole injection material layer 25, an inorganic film layer 27 disposed on the cathode layer 26, and a transparent organic gel layer 28 disposed on the inorganic film layer 27.

[0034] The heat dissipation component 3 includes a copper pillar 33 connected to the bottom of the ultra-thin glass layer 21. A heat-conducting plate 34 is provided on the side of the mounting shell 1 near the copper pillar 33. A heat dissipation fin 35 is connected to the bottom of the heat-conducting plate 34 and is located inside the mounting shell 1. A fan 36 is installed on one side of the mounting shell 1, and an air outlet 37 is opened on the side of the mounting shell 1 away from the fan 36. When the organic light-emitting display device is working, current flows into the organic light-emitting display component 2 through the anode layer 24. The hole injection material layer 25 assists in hole injection, and electrons injected into the cathode layer 26 recombine and emit light internally. The light passes through the flexible polymer film layer 23 and other materials and is emitted outward. The heat generated during operation is first conducted by the ultra-thin glass layer 21 to the bottom copper pillar 33, and then transferred to the heat dissipation fin 35 through the heat-conducting plate 34, increasing the heat dissipation area. At the same time, the fan 36 operates, blowing cold air into the mounting shell 1, which flows through the heat dissipation fin 35 and carries away the heat. The hot air is discharged from the air outlet 37, ensuring that the device operates stably at a suitable temperature.

[0035] The above solutions also have the problem of not being able to quickly disassemble and separate the organic light-emitting display component 2 when it needs to be disassembled for maintenance. Figures 3-4As shown: A first magnetic block 31 is connected to the bottom of the ultra-thin glass layer 21, and a second magnetic block 32 is connected to the side of the mounting shell 1 near the first magnetic block 31. The first magnetic block 31 is set on the second magnetic block 32. The first magnetic block 31 is connected to the bottom of the ultra-thin glass layer 21, and the second magnetic block 32 is fixed in the corresponding position inside the mounting shell 1. When the device is assembled, relying on the property of opposite magnetic poles attracting each other, the first magnetic block 31 is attracted to the second magnetic block 32, which quickly realizes the initial positioning and connection between the organic light-emitting display component 2 and the mounting shell 1, providing a foundation for subsequent stable installation, and facilitating disassembly and maintenance.

[0036] like Figures 1-5 As shown, the mounting housing 1 is equipped with a snap-fit ​​assembly 4, which includes a slot 41 connected to one side of the bottom of the ultra-thin glass layer 21. The slot 42 on the slot 41 serves as a connection interface. A snap-fit ​​plate 43 is slidably connected inside the mounting housing 1. The snap-fit ​​plate 43 is equipped with a telescopic spring 44. During installation, the slot 42 provides an embedding space for the snap-fit ​​plate 43. The two work together to achieve snap-fit, further fixing the organic light-emitting display component 2 to the mounting housing 1, enhancing structural stability, and ensuring the organic light-emitting display component 2 is securely attached within the device. For reliable installation, one end of the telescopic spring 44 is connected to the mounting housing 1, and the other end of the telescopic spring 44 is connected to the clamping plate 43. The clamping plate 43 can slide within the mounting housing 1. One end of the telescopic spring 44 is connected to the mounting housing 1, and the other end is connected to the clamping plate 43. The clamping plate 43 is set in the clamping slot 42. During installation, first press the clamping plate 43 to stretch the telescopic spring 44. Then place the organic light-emitting display component 2 into the mounting housing 1. After releasing the clamping plate 43, the telescopic spring 44 rebounds and tightly clamps the clamping plate 43 into the clamping slot 42. During disassembly, press the clamping plate 43 to disengage it from the clamping slot 42, thus separating the component.

[0037] Working principle:

[0038] like Figures 1-5As shown, firstly, in terms of light emission, current flows in from the anode layer 24, and the hole injection material layer 25 assists in hole injection. The electrons injected into the cathode layer 26 recombine within the device, generating light emission. The light sequentially passes through the flexible polymer film layer 23, the siloxane buffer layer 22, and the ultra-thin glass layer 21 before emitting outwards, achieving the display function. In terms of heat dissipation, the heat generated during operation is first conducted by the ultra-thin glass layer 21 to the bottom copper pillar 33. The copper pillar 33, acting as a highly efficient heat conductor, quickly transfers the heat to the heat-conducting plate 34, which then disperses it to the heat dissipation fins 35. This increases the heat dissipation area and improves efficiency. Simultaneously, the fan 36 blows cool air into the mounting housing 1. The cool air flows through the heat dissipation fins 35, carrying away heat, while the hot air is exhausted from the air outlet 37, maintaining the device's cooling efficiency. Stable operation at suitable temperatures. In terms of installation, positioning, and fixation, relying on the attraction between the opposite magnetic poles of the first magnetic block 31 and the second magnetic block 32, the first magnetic block 31 is attracted to the second magnetic block 32 during device assembly, achieving initial positioning and connection between the organic light-emitting display component 2 and the mounting shell 1, facilitating subsequent installation, disassembly, and maintenance. The snap-fit ​​component 4 further enhances the connection stability. During installation, pressing the snap-fit ​​plate 43 stretches the telescopic spring 44, placing the organic light-emitting display component 2 inside the mounting shell 1. After releasing the snap-fit ​​plate 43, the telescopic spring 44 rebounds, and the snap-fit ​​plate 43 snaps into the slot 42 on the slot 41. During disassembly, pressing the snap-fit ​​plate 43 disengages it from the slot 42, achieving component separation. The coordinated operation of each part ensures the efficient and stable operation of the organic light-emitting display device.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
