Description

Technical Field

[0001] The present application belongs to the field of display technology, and in particular, relates to a light board and a display device. Background Art

[0002] With the rapid development of display technology, Micro-LED display technology has emerged and become a new display technology. Micro-LED displays are composed of hundreds of thousands or even millions of micron-sized RGB light-emitting chips. After the RGB chips are prepared, they need to be transferred to the corresponding light boards. Due to the large number, mass transfer has become a difficulty restricting Micro-LED displays, and it is even more complicated for ultra-large display devices.

[0003] Based on this, there is currently a method of using vibration force or wind force to achieve mass transfer, which specifically includes connecting a vibration source at the loading mold, setting a blowing device on the loading mold side, and relying on the vibration source and the blowing device to make the Micro-LED fall into the loading slot under the action of vibration force or wind force.

[0004] However, the above-mentioned mass transfer method may damage a large number of RGB light-emitting chips during the installation process or may not be installed properly, resulting in low installation efficiency. Summary of the invention

[0059] A first aspect of the present application provides a light board, such as Figure 1 and Figure 2 As shown, it includes a base 10, a vibration mechanism and a driving mechanism 30;

[0060] The base 10 is provided with a first flow channel 100 and a receiving chamber 101 which are interconnected. The first flow channel 100 is used to store fluid and allow fluid to circulate, and the receiving chamber 101 is used to store fluid.

[0061] The vibration mechanism includes a plurality of vibration units 20, which are arranged in an array on the base 10, wherein the vibration unit 20 includes a fixing portion 21 and a vibration portion 22, the fixing portion 21 is connected to the base 10, and the vibration portion 22 is used to carry and position the light-emitting unit 50, and a second flow channel 200 is arranged inside the vibration unit 20, the second flow channel 200 is connected to the first flow channel 100, and each second flow channel 200 in the vibration unit 20 arranged side by side along the first direction is connected to each other;

[0062] The driving mechanism 30 is disposed in the first flow channel 100 , and is used to drive the fluid in the accommodating cavity 101 , the first flow channel 100 and the second flow channel 200 to flow unidirectionally, driving the vibration part 22 to vibrate, so that the vibration part 22 and the light-emitting unit 50 are positioned and fixed.

[0063] The lamp board provided in the embodiment of the present application drives the fluid in the accommodating cavity 101, the first flow channel 100 and the second flow channel 200 to flow unidirectionally through the driving mechanism 30, thereby driving the vibration part 22 to vibrate, so that the light-emitting unit 50 and the vibration part 22 are positioned and fixed. The vibration units 20 arranged in an array can install a huge number of light-emitting units 50, and after installation, they are directly part of the display device, so that the installation efficiency is greatly improved. Furthermore, the light-emitting unit 50 is in the base 10 and basically will not fall off, and the positioning and fixing of the light-emitting unit 50 is achieved by adopting a small vibration method, which is different from the prior art that uses blowing and large-amplitude vibration to adjust the light-emitting chip into the installation groove. In the embodiment of the present application, the driving mechanism 30 drives the fluid to move the vibration part 22 up and down, and the vibration method is relatively milder and will not cause damage to the light-emitting unit 50.

[0064] It should be noted that the specific principle of the vibration of the vibration part 22 to position and fix the vibration part 22 and the light-emitting unit 50 is: when the light-emitting unit 50 needs to be transferred and installed in large quantities, the light-emitting unit 50 will be placed on the vibration unit 20 arranged in an array on the base 10 (specifically, directly in contact with the vibration part 22), and the light-emitting unit 50 is stacked on the vibration part 22 in a disordered manner; then the fluid in the flow channel and the accommodating cavity 101 is driven by the driving mechanism 30, and the fluid flow drives the vibration part 22 to vibrate, thereby driving the light-emitting unit 50 located on the vibration part 22 to vibrate irregularly; until the positioning structure on the light-emitting unit 50 is connected to the vibration part 22, the installation transfer of the light-emitting unit 50 is completed. In application, a fixed magnetic pole 56 is provided on the light-emitting unit 50, and a magnetic attraction member that magnetically cooperates with the fixed magnetic pole 56 is provided on the vibration part 22. During the vibration process, the fixed magnetic pole 56 and the magnetic attraction member attract each other, thereby completing the positioning and fixing of the light-emitting unit 50 and the vibration part 22.

[0065] In applications, such as Figure 1 As shown, Figure 1 It is a cross-sectional view of the lamp panel. The middle of the base 10 is concave inward, and the peripheral side of the base 10 is higher than the middle of the base 10 and a baffle is formed on the peripheral side. After installation, the baffle becomes the frame of the display device. In application, the accommodating cavity 101 is located in the middle of the base 10. This arrangement makes the center of the back of the final display device protrude outward, which is relatively more beautiful. The accommodating cavity 101 divides the first flow channel 100 into two, and the accommodating cavity 101 and the first flow channel 100 are filled with fluid, and the fluid includes but is 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, a plurality of vibration units 20 are arranged side by side along the first direction and the second direction respectively. The first direction and the second direction are the length and width directions of the light board (or display device), and the third direction is the thickness direction of the light board (or display device). The second flow channels 200 in the vibration units 20 arranged side by side along the first direction are interconnected, which means that the vibration units 20 arranged side by side along the length or width direction of the light board, and the second flow channels 200 inside thereof are interconnected, and then connected to the first flow channel 100 and the accommodating cavity 101, so that the fluid can flow in the first flow channel 100, the second flow channel 200 and the accommodating cavity 101, thereby providing driving force to the vibration part 22, so that the vibration part 22 drives the light-emitting unit 50 to vibrate, so that the light-emitting unit 50 and the vibration part 22 are positioned and fixed, and the mass transfer installation of the light-emitting unit 50 is realized.

[0067] In some embodiments, Figure 3 As shown, the driving mechanism 30 includes a pump 31 and a one-way valve 32;

[0068] The pump 31 is installed at the connection point between the installation cavity and the first flow channel 100. The pump 31 is used to cool the fluid in the accommodating cavity 101, the first flow channel 100 and the second flow channel 200, and drive the fluid to flow;

[0069] The one-way valve 32 is installed at one end of the installation cavity away from the pump 31. Thus, by setting the pump 31 and the one-way valve 32, the fluid can flow in one direction in the flow channel, thereby providing driving force to the vibration end 221.

[0070] In application, the pump 31 is a cooling pump 31, which can drive the fluid flow and cool the fluid. Especially after installation, the fluid mainly plays a heat dissipation role, and the fluid will absorb a large amount of heat in the display device, so it needs to be cooled in time after one cycle.

[0071] In some embodiments, Figure 2 As shown, the second flow channel 200 is provided through the fixing part 21, and the vibration unit 20 further includes a transmission structure 23 located in the second flow channel 200, the transmission structure 23 is in transmission connection with the vibration part 22, and the driving mechanism 30 drives the transmission structure 23 to rotate, driving the vibration part 22 to vibrate, so that the vibration part 22 and the light-emitting unit 50 are positioned and fixed. The existence of the transmission structure 23 converts the fluid driving force flowing in the first direction into the driving force that causes the vibration part 22 to vibrate in the third direction, so that the transmission efficiency is faster and the vibration can be made gentler, which can play a certain protective role on the light-emitting unit 50 and prevent it from being damaged by huge vibration.

[0072] In some embodiments, Figure 2As shown, a groove 210 is provided on a side of the fixed portion 21 away from the base 10, and the vibrating portion 22 includes a vibrating end 221 and a connecting column 222. The connecting column 222 is provided on a side of the vibrating end 221 close to the fixed end, and the vibrating end 221 is movably provided in the groove 210. The connecting column 222 is in transmission connection with the transmission structure 23. In this way, the connecting column 222 connects the vibrating end 221 and the transmission structure 23, and the transmission structure 23 transmits the driving force of the flowing fluid to the connecting column 222, so that the connecting column 222 moves in the third direction, thereby driving the vibrating end 221 to vibrate.

[0073] In use, the side surface of the vibration end 221 away from the fixing part 21 is flush with the opening of the groove 210, so that the light-emitting unit 50 is more stable when connected to the vibration end 221. The connecting column 222 is arranged along the third direction, and the connecting column 222 is inserted into the fixing part 21. The two ends of the connecting column 222 are respectively connected to the vibration end 221 and the transmission structure 23. This is conducive to improving the transmission efficiency.

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

[0075] The runner 231 is rotatably disposed in the second flow channel 200;

[0076] The baffle 232 is disposed on the peripheral side of the rotating wheel 231, and the baffle 232 is located in the second flow channel 200;

[0077] The cam 233 is connected to the rotation, the cam 233 and the rotating wheel 231 rotate synchronously, and the cam 233 is transmission-connected to the vibration part 22 .

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

[0079] The process of rotating the rotating wheel 231 arranged in the second flow channel 200 is as follows: the driving mechanism 30 drives the fluid in the flow channel and the accommodating chamber 101 to flow unidirectionally. 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, and the cam 233 rotates synchronously with the rotating wheel 231. The protruding end of the cam 233 is transmission-connected to the vibration part 22, that is, every time the rotating wheel 231 and the cam 233 rotate one circle, 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 the cam 233 and the vibration part 22 means that when the cam 233 rotates, the vibration part 22 is driven to vibrate. In a preferred embodiment, the protruding end of the cam 233 is transmission-connected with the connecting column 222 of the vibration part 22, that is, the end of the connecting column 222 away from the vibration end 221 is located within the rotation track of the cam 233, so that when the cam 233 rotates one circle, the protruding end of the cam 233 will inevitably hit the connecting column 222, thereby causing the vibration end 221 at the other end of the connecting column 222 to vibrate, and at least one vibration will occur for each rotation.

[0081] In some embodiments, Figure 2 As shown, each vibration unit 20 is provided with multiple transmission structures 23 and multiple vibration parts 22, and each transmission structure 23 cooperates with a vibration part 22. In this way, the vibration of the two groups 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 obliquely arranged in the second flow channel 200. In this way, the baffle 232 cooperates with the inner wall of the second flow channel 200 to direct the fluid to a certain point, which is conducive to quickly pushing the baffle 232. Preferably, the baffles 232 are evenly distributed on the circumference of the wheel 231, and each baffle 232 completely blocks the flow channel, so that the driving force of the fluid can be effectively utilized and the flow of the fluid can be completely converted into the drive of the vibration end 221.

[0083] In some embodiments, the vibration part 22 is provided with a connector 223 for positioning and fixing the light-emitting unit 50. The light-emitting unit 50 is provided with a positive and negative circuit electrode and a fixed magnetic pole 56 to form an interlocking structure. The interlocking structure is interlocked with the connector 223 to achieve positioning and fixing of the light-emitting unit 50. In application, the connector 223 includes but is not limited to a magnetic pole. The connector 223 is designed to have a shape for interlocking the positive and negative circuit electrodes and the fixed magnetic pole 56. For example, if the positive and negative circuit electrodes and the fixed magnetic pole 56 on the light-emitting unit 50 protrude outward, the connector 223 is recessed inward, and vice versa.

[0084] In some embodiments, Figure 3 and Figure 4 As shown, a buffer 224 is further provided between the vibration part 22 and the connecting part 223. The buffer 224 includes but is not limited to a spring, and specifically can be a spring with a weak elastic coefficient, so that the rigidity of the connecting part 223 can be weakened, so that the vibration transmission of the vibration part 22 is more efficient.

[0085] In some embodiments, Figure 3 and Figure 4As shown, a retaining structure 40 is further 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, and the retaining structure 40 is used to prevent the light emitting unit 50 from falling. During the installation of the light emitting unit 50, the light emitting unit 50 will vibrate along with the vibration unit 20. To prevent the light emitting unit 50 from falling outside 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.

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

[0087] The seat body 41 is fixedly connected to the base 10, and a cavity 410 communicating with the first flow channel 100 is formed in the seat body 41;

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

[0089] The push member 43 is movably disposed in the cavity 410 , and one end of the push member 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 in a direction away from the base 41 to enclose the light emitting unit 50 on the vibration part 22 to prevent it from falling.

[0091] like Figure 3 As shown, when installing the light-emitting unit 50, firstly, all the enclosure structures 40 around the base 10 are raised, and then the light-emitting unit 50 is placed in the surrounding structure, so that the light-emitting unit 50 can be effectively prevented from falling and being damaged. Figure 7 As shown, by applying pressure to the enclosure structure 40 to reset the pusher 43, the pusher 43 squeezes out 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, Figure 4 As shown, the enclosure structure 40 also includes a limiter 44, which is disposed between the frame 42 and the base 41. When the light-emitting unit 50 is installed, the limiter 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] The present application also provides a display device, such as Figures 5 to 9 As shown, the display device includes the light board, the light-emitting chip and the protective layer 60 described in the first aspect;

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

[0095] The protection layer 60 is disposed on a side of the light emitting chip away from the vibration portion 22 .

[0096] The display device provided in the embodiment of the present application 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 the embodiment of the present application can solve the problem of mass transfer of the light-emitting unit 50, and the installation can be completed simultaneously 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 in sequence. In some embodiments, a composite film layer 55 is also provided between the quantum dot layer 52 and the light-emitting layer 53 to brighten the light generated by the light-emitting layer 53 and emit it evenly. 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 (such as ITO, i.e., indium tin oxide). The function of the substrate layer 54 is to provide a stable platform for supporting other layers and to effectively transmit current. The light-emitting layer 53 contains a material that can generate light, which is usually achieved by emitting light by the recombination of electrons and holes under specific conditions. The quantum dot layer 52, quantum dots are nano-scale semiconductor particles that have 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 the color saturation and display quality. The main function of the encapsulation layer 51 is to protect the internal structure from environmental factors, such as moisture, oxygen, etc., which may cause device performance degradation or failure. In addition, the encapsulation layer 51 may also contain reflective materials or lens designs to improve light extraction efficiency and directionality.

Fig. 9 This is a schematic diagram of the entire display device installed. Figures 6 to 8 As shown, the disordered light-emitting units 50 located on the base 10 are positioned and fixed with the connecting member 223 on the vibration end 221 under the irregular vibration of the vibration unit 20, so as to realize the mass transfer installation of the light-emitting units 50. Then, a protective layer 60 is further provided on the light-emitting units 50 to obtain the final display device.

[0099] In applications, such as Fig. 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 coated on a side of the protective glass 61 close to the light-emitting unit 50 .

[0100] In some embodiments, the baffle is provided with a through hole (not shown in the figure), and the presence of the through hole facilitates the passage of fluid. After the transfer and installation of the light-emitting unit is completed, the vibration part does not need to vibrate, so the fluid in the flow channel mainly plays the role of cooling the display device.

[0101] It should be noted that the specific principle of enabling the fluid to push the baffle with a through hole to rotate is: 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 faster, although some of the fluid will still flow out of the through hole, most of the fluid will still push the baffle and the rotor to rotate; after the installation is completed, the working power of the pump can be reduced to reduce the fluid flow rate, so that the fluid can flow slowly from the through hole, thereby achieving the purpose of heat dissipation.

[0102] In other embodiments, an elastic member (not shown in the figure) is provided between the connecting column and the vibration end. The elastic member includes but is not limited to a spring. This arrangement is to prevent the transmission structure from continuing to transmit the power to the vibration end. Because after the installation of the light-emitting unit is completed, a protective layer will be provided on the light-emitting unit to complete the packaging of the display device. At this time, the elastic member between the connecting column and the vibration end will absorb the force that drives the baffle and the rotating wheel to rotate when the fluid flows, so that the vibration end will not vibrate. Moreover, the fluid in the flow channel can still flow, thereby playing the role of heat dissipation for the display device.

[0103] In application, a heat dissipation channel is specially provided on the base, and the heat dissipation channel can be selectively connected with the first channel and the accommodating cavity. In this way, in the process of installing the light-emitting unit, the heat dissipation channel is not used, and it is chosen not to be connected with the first channel and the accommodating cavity; after the installation is completed and the final display device is obtained, the heat dissipation channel is chosen to be connected with the first channel and the accommodating cavity, and the fluid can circulate through the first channel, the heat dissipation channel and the accommodating cavity to dissipate heat for the display device. In application, the heat dissipation channel can be selectively connected with the first channel and the accommodating cavity: a control valve can be set at the intersection of the first channel and the heat dissipation channel. When in the installation process, the valve of the control valve blocks the heat dissipation channel to prevent the fluid from passing through the heat dissipation channel; when the installation is completed and the display device needs to be cooled, the control valve is adjusted to close the first channel and open the heat dissipation channel.

[0104] The light board and display device provided in the embodiment of the present application cleverly 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 enclosure structures on both sides are raised by driving the flow of the pump and the flow of the fluid in the accommodating cavity to facilitate the subsequent installation of the light-emitting unit and prevent the light-emitting unit from vibrating and falling;

[0106] When installing the light-emitting unit, continue to drive the fluid so that the transmission structure drives the vibration unit to vibrate, and drives the light-emitting unit to vibrate to complete the positioning and fixing of the light-emitting unit;

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