Description

Technical Field

[0001] This application belongs to the field of display technology, and in particular relates to a light panel and display device. Background Technology

[0002] With the rapid development of display technology, Micro-LED display technology has emerged as a new display technology. Micro-LED displays are composed of hundreds of thousands or even millions of RGB light-emitting chips at the micrometer level. After the RGB chips are prepared, they need to be transferred to the corresponding light board. Because of the large number of chips, the mass transfer has become a major challenge for Micro-LED displays, and it is even more complicated for ultra-large-size display devices.

[0003] Based on this, a method has emerged that uses vibration or wind to achieve mass transfer. Specifically, this involves connecting a vibration source to the loading mold and setting a blowing device on the side of the loading mold. The vibration source and the blowing device are used to make the Micro-LEDs fall into the loading tank under the action of vibration or wind.

[0004] However, the aforementioned mass transfer method can damage a large number of RGB LED chips or result in improper installation during the installation process, leading to low installation efficiency. Summary of the Invention

[0005] In view of this, embodiments of this application provide a lamp board and a display device to solve the technical problem that a large number of light-emitting chips are damaged in existing mass transfer operations.

[0006] In a first aspect, embodiments of this application provide a light panel, comprising:

[0007] The base has a first flow channel for fluid flow and a receiving cavity for storing fluid, the first flow channel being connected to the receiving cavity;

[0008] A vibration mechanism includes multiple vibration units arrayed on a base. Each vibration unit includes a fixing part and a vibration part. The fixing part is connected to the base, and the vibration part is used to support and position a light-emitting unit. Each vibration unit also has a second flow channel communicating with a first flow channel. The second flow channels in the vibration units arranged side-by-side along a first direction are interconnected.

[0009] A driving mechanism is provided in the first flow channel. The driving mechanism is used to drive the fluid in the receiving cavity, the first flow channel and the second flow channel to flow in one direction, thereby causing the vibrating part to vibrate, so that the vibrating part is positioned and fixed with the light-emitting unit.

[0010] In some embodiments, the second flow channel passes through the fixed part, and the vibration unit further includes a transmission structure located in the second flow channel. The transmission structure is connected to the vibration part in a transmission manner, and the driving mechanism drives the transmission structure to rotate, thereby causing the vibration part to vibrate, so that the vibration part and the light-emitting unit are positioned and fixed.

[0011] In some embodiments, the fixing part has a groove on the side away from the base, the vibrating part includes a vibrating end and a connecting column disposed on the side of the vibrating end near the fixing part, the vibrating end is movably disposed in the groove, and the connecting column is connected to the transmission structure for transmission.

[0012] In some embodiments, the transmission structure includes:

[0013] The impeller is rotatably disposed within the second flow channel;

[0014] A baffle plate is disposed on the circumference of the rotor, and the baffle plate is located within the second flow channel; and

[0015] A cam is connected to the rotating wheel, and the cam rotates synchronously with the rotating wheel. The cam is also connected to the vibrating part via a transmission connection.

[0016] In some embodiments, the baffle is tilted.

[0017] In some embodiments, the baffle is provided with a through hole.

[0018] In some embodiments, an elastic element is provided between the connecting column and the vibrating end.

[0019] In some embodiments, the vibrating part is provided with a connector for positioning and fixing the light-emitting unit;

[0020] A buffer is also provided between the vibrating part and the connecting member.

[0021] In some embodiments, a barrier structure is provided between the side of the base and the vibration mechanism. The barrier structure is movably disposed on the side of the base and is used to prevent the light-emitting unit from falling off.

[0022] In some embodiments, the enclosure structure includes:

[0023] A seat body is fixedly connected to the base, and a cavity communicating with the first flow channel is provided inside the seat body;

[0024] The frame is connected to the base; and

[0025] A pusher is movably disposed within the cavity, with one end of the pusher connected to the frame;

[0026] When the light-emitting unit is installed, the pusher is propelled by the fluid, and the frame moves away from the base to surround the light-emitting unit located on the vibrating part and prevent it from falling off.

[0027] Alternatively, the enclosure structure may further include a limiting member disposed between the frame and the base. When the light-emitting unit is installed, the limiting member is used to connect the frame and the base to prevent the frame from moving away from the base.

[0028] In some embodiments, the drive mechanism includes:

[0029] A pump is installed at the connection between the mounting cavity and the first flow channel. The pump is used to cool the fluid located in the receiving cavity, the first flow channel and the second flow channel and to drive the fluid flow.

[0030] A one-way valve is installed at the end of the mounting cavity away from the pump.

[0031] Secondly, embodiments of this application provide a display device, including:

[0032] The light panel as described in the first aspect;

[0033] A light-emitting chip, connected to the vibrating part; and

[0034] A protective layer is provided on the side of the light-emitting chip away from the vibrating part.

[0035] The lamp board and display device provided in this application embodiment drive the fluid in the receiving cavity, the first flow channel and the second flow channel to flow unidirectionally through the driving mechanism, causing the vibrating part to vibrate, so that the light-emitting unit is positioned and fixed with the vibrating part. The array of vibrating units can install a large number of light-emitting units, and after installation, they are directly part of the display device. In this way, the installation efficiency is greatly improved. Furthermore, the light-emitting units are in the base, so they will basically not fall off. Moreover, the positioning and fixing of the light-emitting units is achieved by using a small vibration method. Unlike the prior art, which uses blowing and large-amplitude oscillation to move the light-emitting chip into the mounting slot, this application embodiment uses the driving mechanism to drive the fluid to move the vibrating part up and down. The vibration method is relatively gentle and will not cause damage to the light-emitting unit. Attached Figure Description

[0059] The first aspect of this application provides a light panel, such as... Figure 1 and Figure 2 As shown, it includes a base 10, a vibration mechanism, and a drive mechanism 30;

[0060] The base 10 has a first flow channel 100 and a receiving cavity 101 that are interconnected. The first flow channel 100 is used to store fluid and to allow fluid to flow, and the receiving cavity 101 is used to store fluid.

[0061] The vibration mechanism includes multiple vibration units 20, which are arrayed on the base 10. Each vibration unit 20 includes a fixing part 21 and a vibration part 22. The fixing part 21 is connected to the base 10, and the vibration part 22 is used to support and position the light-emitting unit 50. The vibration unit 20 has a second flow channel 200 inside, which is connected to the first flow channel 100. Moreover, the second flow channels 200 in the vibration units 20 arranged side by side along the first direction are interconnected.

[0062] The driving mechanism 30 is located in the first flow channel 100. The driving mechanism 30 is used to drive the fluid in the receiving cavity 101, the first flow channel 100 and the second flow channel 200 to flow in one direction, thereby causing the vibrating part 22 to vibrate, so that the vibrating part 22 and the light-emitting unit 50 are positioned and fixed.

[0063] The lamp board provided in this application embodiment uses a driving mechanism 30 to drive the fluid in the receiving cavity 101, the first flow channel 100, and the second flow channel 200 to flow unidirectionally, causing the vibrating part 22 to vibrate, so that the light-emitting unit 50 is positioned and fixed with the vibrating part 22. The array of vibrating units 20 can install a large number of light-emitting units 50, and after installation, they are directly part of the display device, thus greatly improving the installation efficiency. Furthermore, the light-emitting units 50 are in the base 10, so they will basically not fall off. Moreover, the positioning and fixing of the light-emitting units 50 is achieved by using a small vibration method, which is different from the prior art that uses blowing and large-amplitude oscillation to move the light-emitting chip into the mounting slot. In this application embodiment, the driving mechanism 30 drives the fluid to move the vibrating part 22 up and down. The vibration method is relatively gentle and will not cause damage to the light-emitting unit 50.

[0064] It should be noted that the specific principle behind the vibration of the vibrating part 22 to fix the position of the vibrating part 22 and the light-emitting unit 50 is as follows: When a large-scale transfer and installation of the light-emitting unit 50 is required, the light-emitting unit 50 is placed on the vibrating part 20 arranged in an array on the base 10 (specifically, in direct contact with the vibrating part 22). At this time, the light-emitting unit 50 is randomly stacked on the vibrating part 22. Then, the fluid located in the flow channel and the receiving cavity 101 is driven by the driving mechanism 30. The fluid flow causes the vibrating part 22 to vibrate, thereby causing the light-emitting unit 50 located on the vibrating part 22 to vibrate irregularly. This continues until the positioning structure on the light-emitting unit 50 connects with the vibrating part 22, thus completing the installation and transfer of the light-emitting unit 50. In application, the light-emitting unit 50 is provided with a fixed magnetic pole 56, and the vibrating part 22 is provided with a magnetic suction component that magnetically engages with the fixed magnetic pole 56. During the vibration process, the fixed magnetic pole 56 and the magnetic suction component attract each other, thereby completing the positioning and fixation of the light-emitting unit 50 and the vibrating part 22.

[0065] In applications, such as Figure 1 As shown, Figure 1 The diagram shows a cross-sectional view of the light panel. The center of the base 10 is recessed inwards, and the periphery of the base 10 is higher than the center, forming a baffle. After installation, the baffle becomes the frame of the display device. In application, the receiving cavity 101 is located in the center of the base 10. This arrangement results in the central part of the back of the final display device protruding outwards, which is relatively more aesthetically pleasing. The receiving cavity 101 divides the first flow channel 100 into two parts. Both the receiving cavity 101 and the first flow channel 100 are filled with fluid, including but not limited to water, coolant, etc.

[0066] In applications, such as Figure 1As shown, the vibration unit 20 array is arranged on the base 10: that is, multiple vibration units 20 are arranged side by side along the first direction and the second direction. The first direction and the second direction are the length and width directions of the lamp panel (or display device), and the third direction is the thickness direction of the lamp panel (or display device). The second flow channels 200 in the vibration units 20 arranged side by side along the first direction are interconnected. This means that the second flow channels 200 inside the vibration units 20 arranged side by side along the length or width direction of the lamp panel are interconnected and then connected to the first flow channel 100 and the receiving cavity 101. This ensures that the fluid flows in the first flow channel 100, the second flow channel 200 and the receiving cavity 101, thereby providing driving force to the vibration part 22, causing the vibration part 22 to drive the light-emitting unit 50 to vibrate, thereby positioning and fixing the light-emitting unit 50 with the vibration part 22, realizing the mass transfer and installation of the light-emitting unit 50.

[0067] In some embodiments, such as Figure 3 As shown, the drive mechanism 30 includes a pump 31 and a check valve 32;

[0068] Pump 31 is installed at the connection between the mounting cavity and the first flow channel 100. Pump 31 is used to cool the fluid located in the receiving cavity 101, the first flow channel 100 and the second flow channel 200 and drive the fluid flow.

[0069] The one-way valve 32 is installed at the end of the mounting cavity away from the pump 31. In this way, the pump 31 and the one-way valve 32 can achieve unidirectional flow of fluid in the flow channel, thereby providing driving force to the vibrating end 221.

[0070] In this application, pump 31 is a cooling pump, which serves to drive fluid flow while also cooling the fluid. Especially after installation, the fluid primarily serves to dissipate heat, absorbing a significant amount of heat from the display device, so it needs to be cooled promptly after each cycle.

[0071] In some embodiments, such as Figure 2 As shown, the second flow channel 200 passes through the fixed part 21. The vibration unit 20 also includes a transmission structure 23 located within the second flow channel 200. The transmission structure 23 is connected to the vibration part 22. The drive mechanism 30 drives the transmission structure 23 to rotate, causing the vibration part 22 to vibrate, thereby fixing the vibration part 22 to the light-emitting unit 50. The presence of the transmission structure 23 converts the fluid driving force flowing in the first direction into a driving force that causes the vibration part 22 to vibrate in the third direction. This results in faster transmission efficiency and gentler vibration, providing some protection for the light-emitting unit 50 and preventing it from being damaged by excessive vibration.

[0072] In some embodiments, such as Figure 2As shown, the fixing part 21 has a groove 210 on the side away from the base 10. The vibrating part 22 includes a vibrating end 221 and a connecting column 222. The connecting column 222 is located on the side of the vibrating end 221 near the fixing part 21. The vibrating end 221 is movably disposed in the groove 210. The connecting column 222 is connected to the transmission structure 23. Thus, the connecting column 222 connects the vibrating end 221 and the transmission structure 23. The transmission structure 23 transmits the driving force of the flowing fluid to the connecting column 222, causing the connecting column 222 to move in a third direction, thereby driving the vibrating end 221 to vibrate.

[0073] In application, the surface of the vibrating end 221 furthest from the fixing part 21 is flush with the opening of the groove 210. This ensures greater stability when the light-emitting unit 50 is connected to the vibrating end 221. The connecting post 222 is arranged along the third direction and passes through the fixing part 21. Both ends of the connecting post 222 are connected to the vibrating end 221 and the transmission structure 23, respectively. This helps to improve transmission efficiency.

[0074] In some embodiments, such as Figure 1 and Figure 2 As shown, the transmission structure 23 includes a rotating wheel 231, a baffle 232, and a cam 233;

[0075] The rotor 231 is rotatably disposed within the second flow channel 200;

[0076] The baffle 232 is disposed on the periphery of the rotor 231 and is located within the second flow channel 200;

[0077] Cam 233 is connected to rotation, cam 233 rotates synchronously with wheel 231, and cam 233 is connected to vibration unit 22 for transmission.

[0078] In application, the working principle of transmission structure 23 is as follows:

[0079] The process of the rotating wheel 231, which is rotatably disposed in the second flow channel 200, rotating is as follows: the driving mechanism 30 drives the fluid in the flow channel and the receiving cavity 101 to flow in one direction. When the fluid flows through the baffle 232 located in the second flow channel 200, it will be blocked. At this time, the fluid pushes the baffle 232 to rotate, thereby causing the entire rotating wheel 231 to rotate. The cam 233 rotates synchronously with the rotating wheel 231. The protruding end of the cam 233 is connected to the vibration part 22. That is, every time the rotating wheel 231 and the cam 233 rotate once, the protruding end of the cam 233 will lift the vibration part 22, thereby causing the vibration part 22 to vibrate.

[0080] It should be noted that the transmission connection between cam 233 and vibrating part 22 means that when cam 233 rotates, it drives vibrating part 22 to vibrate. In a preferred embodiment, the protruding end of cam 233 is transmissionally connected to the connecting post 222 of vibrating part 22, that is, the end of connecting post 222 away from vibrating end 221 is located within the rotation trajectory of cam 233. Thus, when cam 233 rotates one revolution, the protruding end of cam 233 will inevitably hit the connecting post 222, thereby causing the vibrating end 221 at the other end of connecting post 222 to vibrate. In this way, at least one vibration will occur for each revolution.

[0081] In some embodiments, such as Figure 2 As shown, each vibration unit 20 is provided with multiple sets of transmission structures 23 and multiple vibration parts 22, with each transmission structure 23 cooperating with one vibration part 22. In this way, the vibration of the two sets of vibration parts 22 can further improve the transfer and installation efficiency of the light-emitting unit 50.

[0082] In application, the baffle 232 is inclinedly disposed within the second flow channel 200. Thus, the baffle 232 engages with the inner wall of the second flow channel 200 to control the fluid at a specific point, facilitating rapid propulsion of the baffle 232. Preferably, the baffles 232 are evenly distributed around the circumference of the impeller 231, and each baffle 232 completely blocks the flow channel. This effectively utilizes the driving force of the fluid, completely converting the fluid flow into driving the vibrating end 221.

[0083] In some embodiments, the vibrating part 22 is provided with a connector 223 for positioning and fixing the light-emitting unit 50. The light-emitting unit 50 has a circuit positive and negative pole and a fixed magnetic pole 56 forming a fitting structure. The fitting structure is fitted and connected to the connector 223 to achieve the positioning and fixing of the light-emitting unit 50. In application, the connector 223 includes, but is not limited to, magnetic poles. The connector 223 is designed with a shape for the circuit positive and negative poles and the fixed magnetic pole 56 to fit together. For example, if the circuit positive and negative poles and the fixed magnetic pole 56 on the light-emitting unit 50 protrude outward, then the connector 223 is recessed inward, and vice versa.

[0084] In some embodiments, such as Figure 3 and Figure 4 As shown, a buffer 224 is also provided between the vibrating part 22 and the connecting member 223. The buffer 224 includes, but is not limited to, a spring, specifically a spring with a low elastic coefficient, which can weaken the rigidity of the connecting member 223 and make the vibration transmission of the vibrating part 22 more efficient.

[0085] In some embodiments, such as Figure 3 and Figure 4As shown, a retaining structure 40 is also provided between the side of the base 10 and the vibration mechanism. The retaining structure 40 is movably provided on the side of the base 10 to prevent the light-emitting unit 50 from falling off. During the installation of the light-emitting unit 50, the light-emitting unit 50 will vibrate with the vibration unit 20. To prevent the light-emitting unit 50 from falling off the base 10, the retaining structure 40 is provided on the side of the base 10 to prevent the light-emitting unit 50 from falling off.

[0086] In some embodiments, such as Figure 4 As shown, the enclosure structure 40 includes a base 41, a frame 42, and a pusher 43;

[0087] The seat 41 is fixedly connected to the base 10, and a cavity 410 communicating with the first flow channel 100 is opened inside the seat 41.

[0088] The frame 42 is connected to the base 41;

[0089] The pusher 43 is movably disposed within the cavity 410, and one end of the pusher 43 is connected to the frame 42;

[0090] When the light-emitting unit 50 is installed, the pusher 43 is pushed by the fluid, and the frame 42 moves away from the base 41 to surround the light-emitting unit 50 located on the vibrating part 22 and prevent it from falling off.

[0091] like Figure 3 As shown, when starting the installation of the light-emitting unit 50, first raise all the surrounding structures 40 around the base 10, and then place the light-emitting unit 50 inside the surrounding structures. This effectively prevents the light-emitting unit 50 from falling and being damaged. After installation, as shown... Figure 7 As shown, by applying pressure to the enclosure structure 40, the pusher 43 is reset, and the pusher 43 squeezes the fluid in the cavity 410 and flows into the second flow channel 200 or the first flow channel 100 to continue flowing.

[0092] In other embodiments, such as Figure 4 As shown, the enclosure structure 40 also includes a limiting member 44, which is located between the frame 42 and the base 41. When the light-emitting unit 50 is installed, the limiting member 44 is used to connect the frame 42 and the base 41 to prevent the frame 42 from moving away from the base 41.

[0093] This application also provides a display device, such as... Figures 5 to 9 As shown, the display device includes the lamp board, light-emitting chip, and protective layer 60 as described in the first aspect;

[0094] The light-emitting chip is connected to the vibrating part 22;

[0095] The protective layer 60 is located on the side of the light-emitting chip away from the vibrating part 22.

[0096] The display device provided in this application embodiment has all the beneficial effects described in the first aspect because it has the lamp board described in the first aspect. The display device provided in this application embodiment can solve the problem of mass transfer of the light-emitting unit 50, and the installation can be completed synchronously using the heat dissipation device of the display device.

[0097] In applications, such as Figure 5 As shown, the light-emitting unit 50 includes a substrate layer 54, a light-emitting layer 53, a quantum dot layer 52, and an encapsulation layer 51 arranged sequentially. In some embodiments, a composite film layer 55 is further provided between the quantum dot layer 52 and the light-emitting layer 53 to enhance the brightness and uniform emission of the light generated by the light-emitting layer 53. The substrate layer 54 is the basic part of the light-emitting unit 50 and is made of a conductive material, such as a metal or a transparent conductive oxide (e.g., ITO, indium tin oxide). The function of the substrate layer 54 is to provide a stable platform for supporting other layers and to efficiently transmit current. The light-emitting layer 53 contains a material capable of generating light, typically through the recombination of electrons and holes under specific conditions. The quantum dot layer 52 uses quantum dots, which are nanoscale semiconductor particles with unique optical and electrical properties. When excited, quantum dots can emit very pure colors, and their emission wavelength can be precisely controlled by changing the size of the quantum dots. Therefore, adding a quantum dot layer 52 to the light-emitting unit 50 can significantly improve color saturation and display quality. The primary function of the encapsulation layer 51 is to protect the internal structure from environmental factors such as moisture and oxygen, which can lead to performance degradation or failure of the device. In addition, the encapsulation layer 51 may also contain reflective materials or lens designs to improve light extraction efficiency and directionality.

[0098] Figure 6 This is a schematic diagram illustrating the process of installing the light-emitting unit 50. Figure 7 This is a schematic diagram showing the completed installation of the light-emitting unit 50. Figure 9 This is a schematic diagram showing the entire display device after installation. Figures 6 to 8 As shown, the disordered light-emitting units 50 located on the base 10 are positioned and fixed to the connectors 223 on the vibration end 221 under the irregular vibration of the vibration unit 20, realizing the mass transfer and installation of the light-emitting units 50. Then, a protective layer 60 is added to the light-emitting units 50 to obtain the final display device.

[0099] In applications, such as Figure 9 As shown, the protective layer 60 includes a protective glass 61 and an adhesive layer 62, wherein the adhesive layer 62 is a strong adhesive heat-resistant adhesive, and the adhesive layer 62 is applied to the side of the protective glass 61 near the light-emitting unit 50.

[0100] In some embodiments, the baffle is provided with a through hole (not shown in the figure), which facilitates the passage of fluid. After the transfer and installation of the light-emitting unit is completed, the vibration of the vibrating part is no longer required, so the fluid in the flow channel at this time mainly serves to dissipate heat from the display device.

[0101] It should be noted that the specific principle by which the fluid drives the baffle with the through hole to rotate is as follows: When installing the light-emitting unit, the power of the pump can be increased to increase the flow rate of the fluid in the flow channel. At this time, when the fluid flow rate is high, although some fluid will still flow out from the through hole, most of the fluid will still drive the baffle and the rotor to rotate. After the installation is completed, the working power of the pump can be reduced to decrease the fluid flow rate, so that the fluid flows slowly through the through hole, thereby achieving the purpose of heat dissipation.

[0102] In some embodiments, an elastic element (not shown in the figure) is provided between the connecting post and the vibrating end. The elastic element includes, but is not limited to, a spring. This arrangement is to prevent the transmission structure from continuing to transmit power to the vibrating end. Because after the light-emitting unit is installed, a protective layer is applied to the light-emitting unit to complete the encapsulation of the display device. At this time, the elastic element between the connecting post and the vibrating end absorbs the force that drives the baffle and the rotating wheel to rotate during fluid flow, thus preventing the vibrating end from vibrating. Furthermore, the fluid in the flow channel can still flow, thereby serving to dissipate heat from the display device.

[0103] In this application, a dedicated heat dissipation channel is provided on the base, which can be selectively connected to the first channel and the receiving cavity. Thus, during the installation of the light-emitting unit, the heat dissipation channel is not needed, and it is not connected to the first channel and the receiving cavity at this time. After installation is completed and the final display device is obtained, the heat dissipation channel is connected to the first channel and the receiving cavity, allowing fluid to circulate through the first channel, the heat dissipation channel, and the receiving cavity to dissipate heat from the display device. In this application, the heat dissipation channel can be selectively connected to the first channel and the receiving cavity: a control valve can be installed at the intersection of the first channel and the heat dissipation channel. During installation, the valve blocks the heat dissipation channel, preventing fluid from passing through it; after installation, when heat dissipation of the display device is required, the control valve is adjusted to close the first channel and open the heat dissipation channel.

[0104] The lamp board and display device provided in this application embodiment ingeniously apply the heat dissipation device (i.e., cooling pump and fluid) of the display device to the installation process of the light-emitting unit. Specifically, it includes:

[0105] Before installing the light-emitting unit, the pump drives the flow of fluid in the receiving cavity to raise the enclosure structure on both sides to facilitate the subsequent installation of the light-emitting unit and prevent the light-emitting unit from vibrating and falling off.

[0106] During the installation of the light-emitting unit, the driving fluid continues to cause the transmission structure to drive the vibration unit to vibrate, thereby causing the light-emitting unit to vibrate and complete the positioning and fixing of the light-emitting unit;

[0107] After the light-emitting unit is installed, the fluid located in the flow channel and the receiving cavity serves as a heat dissipation medium to cool the display device.
