Description

Light panels and display devices

[0001] This application claims priority to Chinese Patent Application No. CN2024115553063, filed on November 4, 2024, entitled "Light Panel and Display Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of mass transfer technology of LED chips, and more particularly to an LED board and a display device. Background Technology

[0003] With the innovation and development of LED (light-emitting diode) technology, Micro-LED (Micro Light Emitting Diode Display) technology has emerged as a new generation of display technology. It involves miniaturizing and matrixing the traditional LED structure, reducing the size of a single LED chip to tens or even a few micrometers, and enabling individual addressing and driving of each LED pixel. Due to its advantages such as high resolution, high brightness, long lifespan, wide operating temperature range, strong anti-interference ability, fast response speed, and low power consumption, Micro-LED has significant application value in high-resolution displays, helmet displays, augmented reality displays, high-speed visible light communication, micro-projectors, optogenetics, and wearable electronics.

[0004] A full-color-gamut Micro-LED display is assembled on a substrate using red, green, and blue (RGB) Micro-LED chips arranged in a specific pattern. Traditional RGB displays use three chips of red, green, and blue evenly spaced on a horizontal plane to create the RGB effect. Each group has a relatively large size and is difficult to assemble, requiring the red, green, and blue chips to be arranged sequentially. This results in a large number of chips being transferred in a mass transfer process, generally necessitating an additional transfer mechanism for the mass transfer of LEDs. Consequently, the mass transfer process for Micro-LEDs has high requirements, resulting in low efficiency and poor accuracy. Summary of the Invention

[0005] The purpose of this application is to provide a lamp board and display device that enables the mass transfer and installation of LED chips through the structure of the lamp board itself, thereby reducing the requirements of the mass transfer process for Micro-LEDs.

[0006] This application discloses a light panel for use in a display panel. The light panel includes a base plate, multiple mounting components, a base circuit board, and multiple LEDs. Multiple mounting components are laid flat on the base plate. Each mounting component includes a main body, an airflow circulation component and a first expansion member disposed within the main body, a first force transmission member connected to the first expansion member, and a vibrating plate connected to the first force transmission member. The airflow circulation component is interconnected with the first expansion member, and the first force transmission member is drivenly connected to the first expansion member. The first expansion member drives the first force transmission member to move, thereby lifting the vibrating plate. The base circuit board is disposed on the multiple mounting components and has multiple mounting slots. Multiple LEDs are disposed on the base circuit board. When the base circuit board operates, it generates heat to heat the gas inside the airflow circulation component, causing the first expansion member to expand and drive the first force transmission member to move, lifting the vibrating plate. After being lifted, the vibrating plate pushes the base circuit board, causing the multiple LEDs located on the base circuit board to vibrate, gradually completing the transfer and installation of the LEDs.

[0007] Optionally, the mounting assembly further includes a first one-way valve and a second one-way valve. The airflow circulation component includes a heating chamber, a first airflow channel and a second airflow channel for connecting the heating chamber, a first blocking member disposed on the first airflow channel, a second blocking member disposed on the second airflow channel, a first air intake channel and a second air intake channel. The first one-way valve is used to connect the first expansion member and the first airflow channel, and the second one-way valve is used to connect the first expansion member and the second airflow channel. The first blocking member has a first chamber, which is connected to the first airflow channel through the first air intake channel. The second blocking member has a second chamber, which is connected to the heating chamber through the second air intake channel. The first state of the first blocking member is to disconnect the connection between the first airflow channel and the heating chamber, and the second state of the first blocking member is to open the connection between the first airflow channel and the heating chamber. The first state of the second blocking member is to disconnect the connection between the heating chamber and the second airflow channel, and the second state of the second blocking member is to open the connection between the heating chamber and the second airflow channel.

[0008] Optionally, the mounting assembly further includes a first force-relieving plate and a second force-transmitting member. The first force-relieving plate is movably disposed within the main body. One end of the second force-transmitting member is connected to the first expansion member, and the other end is connected to the first force-relieving plate. When the first expansion member expands, it will drive the second force-transmitting member to move, thereby pushing the first force-relieving plate connected to the second force-transmitting member.

[0009] Optionally, the mounting assembly further includes a first mounting magnetic block and a second mounting magnetic block, which are respectively disposed at both ends of the main body. The first mounting magnetic block and the second mounting magnetic block are magnetically attracted to each other to fix adjacent mounting assemblies.

[0010] Optionally, the mounting assembly further includes a first elastic element, one end of which is connected to the main body and the other end of which is connected to the vibration plate.

[0011] Optionally, the light panel further includes a blocking assembly disposed on the base plate. The blocking assembly includes a blocking member, a second expansion member, and a first lifting structure. The second expansion member is fixed between the base plate and the blocking member. One end of the first lifting structure is connected to the second expansion member, and the other end abuts against the blocking member. When the second expansion member expands, the first lifting structure moves toward the blocking member to lift the blocking member.

[0012] Optionally, the blocking assembly further includes a second lifting structure and a second releasing plate. The second releasing plate is movably disposed on the base plate. One end of the second lifting structure is connected to the second expansion member, and the other end is connected to the second releasing plate. The second lifting structure is symmetrically disposed with the first lifting structure.

[0013] Optionally, the light panel further includes a strong fixing member, which is disposed between the base plate and the blocking member for fixing the blocking member.

[0014] Optionally, the lamp panel further includes a support spring, one end of which is connected to the mounting assembly and the other end of which is connected to the base circuit board.

[0015] This application also discloses a display device, including a driving circuit and a display panel, the display panel including a glass substrate and a lamp plate as described above, and the driving circuit being used to drive the display panel.

[0016] The lamp board of this application, through the structure of the mounting components, can achieve mass transfer and installation of lamp beads through the structure of the lamp board itself, without the need for an additional transfer mechanism to perform mass transfer of lamp beads. This reduces the requirements of the mass transfer process for Micro-LEDs and improves the mass transfer efficiency. Furthermore, it can convert the waste heat generated in the lamp board into energy for mass transfer and installation of lamp beads, thus converting heat into mechanical energy. This saves production costs to a certain extent and has broad application prospects. Attached Figure Description

[0031] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] As shown in Figures 1 and 2, a lamp panel 100 is disclosed as a first embodiment of this application, applied to a display panel. The lamp panel 100 includes a base plate 110, multiple mounting components 200, a base circuit board 120, and multiple LED beads 130. The multiple mounting components 200 are laid flat on the base plate 110. Each mounting component 200 includes a main body 210, an airflow circulation component 220 disposed within the main body 210, a first expansion member 230, a first force transmission member 240 connected to the first expansion member 230, and a first force transmission member 240 connected to the first force transmission member 230. The vibrating plate 250 is connected to component 240. The airflow circulation component 220 is interconnected with the first expansion component 230. The first force transmission component 240 is drivenly connected to the first expansion component 230. When the first expansion component 230 expands, it will drive the first force transmission component 240 to move, thereby lifting the vibrating plate 250 connected to the first force transmission component 240. The base circuit board 120 is disposed on multiple mounting components 200, and the base circuit board 120 is provided with multiple mounting slots 121. Multiple LED beads 130 are disposed on the base circuit board. On plate 120; the base circuit board 120 generates heat during operation, and the heat is conducted through the main body 210 to the airflow circulation component 220 to heat the gas inside the airflow circulation component 220, causing the gas to expand and enter the first expansion member 230, so that the first expansion member 230 expands, driving the first force transmission member 240 to move and lift the vibrating plate 250. After the vibrating plate 250 is lifted, it will push the base circuit board 120, so that multiple components located on the base circuit board 120... The LED bead 130 vibrates to gradually complete the transfer and installation of the LED bead 130. In this embodiment, the mounting assembly 200 also includes a first mounting magnetic block 300 and a second mounting magnetic block 310. The first mounting magnetic block 300 and the second mounting magnetic block 310 are respectively disposed at both ends of the main body 210. The first mounting magnetic block 300 and the second mounting magnetic block 310 are magnetically attracted to fix adjacent mounting assemblies 200, so that multiple mounting assemblies 200 can be laid flat on the base plate 110.

[0033] In this embodiment, when installing the LED beads 130, the LED beads 130 are first spread out on the base circuit board 120, as shown in Figure 4. At this time, the LED beads 130 are placed randomly on the base circuit board 120. Then, the base circuit board 120 is powered on to generate heat. The generated heat is radiated to the vibrating plate 250 and the main body 210 of the mounting assembly 200, and conducted through the main body 210 to the airflow circulation component 220 to heat the gas inside the airflow circulation component 220. The gas expands due to the heat and enters the first expansion member 230. The first expansion member 230 expands after receiving the gas to push up the first expansion member 230. The force transmission component 240 moves the vibrating plate 250 to push the base circuit board 120 away from the base plate 110, causing the LED beads 130 on the base circuit board 120 to vibrate. Subsequently, under the weight of the LED beads 130 and the base circuit board 120, the vibrating plate 250 is squeezed towards the base plate 110, causing the gas in the first expansion member 230 to enter the airflow circulation component 220 for reheating. During this process, new heated and expanded gas enters the first expansion member 230, forming a gas circulation between the first expansion member 230 and the airflow circulation component 220, thus allowing the first expansion member... The continuous expansion, deformation, and return to original shape of the 230 cause the first force transmission component 240 to reciprocate, realizing the reciprocating motion of the vibrating plate 250. This repeatedly pushes the base circuit board 120, causing it to vibrate irregularly. This, in turn, causes the multiple LED beads 130 located on the base circuit board 120 to vibrate irregularly, gradually adjusting the position of the LED beads 130 until they are installed in the mounting slots 121 on the base circuit board 120, achieving a large-scale transfer and installation of the LED beads 130. The state of the LED beads 130 after installation is shown in Figure 5. After all the LED beads 130 are installed, the glass substrate 600 is finally placed on top of the LED beads 130 to press them down. The installation of the LED chips 130 is completed, and the state of the glass substrate 600 after installation is shown in Figure 6. In general, the lamp board 100 of this embodiment, by setting the structure of the mounting component 200, can realize the mass transfer and installation of LED chips 130 through the structure of the lamp board 100 itself, without the need for an additional transfer mechanism to perform mass transfer of LED chips 130. This reduces the requirements of the mass transfer process of Micro-LED and improves the mass transfer efficiency. In addition, it can convert the waste heat generated in the lamp board 100 into the mass transfer and installation of LED chips 130 for use, converting heat into mechanical energy for use, which saves production costs to a certain extent and has broad application prospects.It should be noted that the main body 210 and the airflow circulation component 220 of the mounting assembly 200 are made of a material with thermal conductivity, so that the heat generated when the base circuit board 120 is working can be transferred through the main body 210 and the airflow circulation component 220 to heat the gas located in the airflow circulation component 220; the first expansion member 230 is made of a high-temperature resistant, elastic, and deformable material, such as nitrile rubber or styrene-butadiene rubber. Furthermore, in order to enable the vibrating plate 250 to vibrate better, the first expansion member 230 is circular before expansion. Two first force transmission members 240 are provided, with one end of each first force transmission member 240 disposed on the first expansion member 230, and the other ends respectively disposed on both ends of the vibrating plate 250 near the base plate 110, forming a triangular structure as shown in Figure 2, so that the vibrating plate 250 generates irregular vibration as the two first force transmission members 240 move.

[0034] Specifically, the specific structure of the mounting assembly 200 is shown in Figure 2. The mounting assembly 200 further includes a first one-way valve 260 and a second one-way valve 270. The airflow circulation component 220 includes a heating chamber 221, a first airflow channel 222 and a second airflow channel 223 for connecting the heating chamber 221, a first blocking member 224 disposed on the first airflow channel 222, a second blocking member 225 disposed on the second airflow channel 223, a first air intake channel 226 and a second air intake channel 227. The first one-way valve 260 is used to connect the first expansion member 230 and the first airflow channel 222. The first one-way valve 260 allows... Gas from the first expander 230 can only enter the first airflow channel 222 from the first expander 230 in one direction, and cannot enter the first expander 230 from the first airflow channel 222. The second one-way valve 270 connects the first expander 230 and the second airflow channel 223, ensuring that gas from the second airflow channel 223 can only enter the first expander 230 from the second airflow channel 223 in one direction, and cannot enter the second airflow channel 223 from the first expander 230. The first blocking member 224 is provided with a first chamber 224a, which connects to the first airflow channel. 222 is connected via the first air intake channel 226. The second blocking member 225 is provided with a second chamber 225a, which is connected to the heating chamber 221 via the second air intake channel 227. The first state of the first blocking member 224 is to block the connection between the first air intake channel 222 and the heating chamber 221; the second state of the first blocking member 224 is to open the connection between the first air intake channel 222 and the heating chamber 221. The first state of the second blocking member 225 is to block the connection between the heating chamber 221 and the second air intake channel 223; the second state of the second blocking member 225 is to open the connection between the heating chamber 221 and the second air intake channel 224. The connection of the second airflow channel 223; it should be noted that the first one-way valve 260 and the second one-way valve 270 can be composed of an elastic element and a ball plug as shown in Figure 2, or they can be one-way valves formed by other structural combinations, as long as they meet the condition of restricting the unidirectional flow of gas. The structure is not limited to this, and the designer can choose the design according to the actual situation, which will not be elaborated here; springs can be installed in the first chamber 224a and the second chamber 225a so that when the first blocking element 224 and the second blocking element 225 switch from the second state to the first state, the springs can play an auxiliary role to speed up the switching speed.

[0035] The specific details of the airflow circulation between the airflow circulation component 220 and the first expansion member 230 are as follows: When the base circuit board 120 has not yet started working, both the first one-way valve 260 and the second one-way valve 270 are closed, the first blocking member 224 is in the first state, and the second blocking member 225 is also in the first state; the gas has not yet circulated. However, when the base circuit board 120 starts working, heat is conducted to the airflow circulation component 220 to heat the gas located in the heating chamber 221. At this time, the gas expands after being heated, and the expanded gas enters the second chamber 225a of the second blocking member 225 through the second air intake channel 227, thereby expanding the area of ​​the second chamber 225a to move the position of the second blocking member 225. The second blocking member 225 is switched from the first state to the second state, that is, the second airflow channel 223 and the heating chamber 221 are connected. The expanding gas will then pass through the second airflow channel 223, opening the second one-way valve 270 to enter the first expanding member 230, causing the first expanding member 230 to expand. The expanded first expanding member 230 will push the first force transmission member 240, causing the first force transmission member 240 to move away from the base plate 110, thereby pushing the vibrating plate 250 away from the base plate 110 and pushing the base circuit board 120, causing the lamp beads 130 on the base circuit board 120 to vibrate. During this process, since most of the expanded gas in the heating chamber 221 passes through the second airflow channel 225... 3. When gas enters the first expansion member 230, the gas pressure in the heating chamber 221 will decrease slightly. The gas in the second chamber 225a of the second barrier member 225 will re-enter the heating chamber 221 through the second air intake channel 227, so that the second barrier member 225 switches to the first state and the second one-way valve 270 closes. When the vibrating plate 250 is lifted to push the base circuit board 120, under the action of the mass of the lamp bead 130 and the base circuit board 120, the vibrating plate 250 will be squeezed towards the base plate 110. The first force transmission member 240 will squeeze the first expansion member 230, so that the first one-way valve 260 is opened, and the gas in the first expansion member 230 enters the first airflow channel 222. Gas in the airflow channel 222 enters the first chamber 224a of the first blocking member 224 from the first air intake channel 226, thereby expanding the area of ​​the first chamber 224a to move the position of the first blocking member 224 and change the first blocking member 224 from the first state to the second state, that is, the first airflow channel 222 and the heating chamber 221 are connected, and the gas re-enters the heating chamber 221 for heating. As most of the gas in the first expansion member 230 enters the heating chamber 221 through the first airflow channel 222, the first one-way valve 260 will gradually close, and the gas in the first chamber 224a will re-enter the first airflow channel 222, thereby changing the first blocking member 224 from the second state to the first state.This repeated airflow circulation causes the vibrating plate 250 to move continuously towards and away from the base plate 110, achieving reciprocating motion. This repeatedly pushes the base circuit board 120, causing multiple LED beads 130 located on the base circuit board 120 to vibrate, gradually adjusting the position of the LED beads 130 until they are installed in the mounting slots 121 on the base circuit board 120, achieving mass transfer and installation of the LED beads 130. It should be noted that the airflow circulation process in the airflow circulation component 220 and the first expansion member 230 is roughly as described above. In actual operation, the gas in the first expansion member 230 is also slowly heated, but the expansion of the gas in the first expansion member 230 during heating is slightly weaker than that of the gas in the heating chamber 221. The slow heating of the gas in the first expansion member 230 prevents the temperature drop of the gas in the first expansion member 230 from being too large.

[0036] The mounting assembly 200 further includes a first elastic element 320, one end of which is connected to the main body 210 and the other end to the vibrating plate 250. Multiple first elastic elements 320 are provided and evenly distributed on the side of the vibrating plate 250 near the base plate 110. This allows the first elastic element 320 to provide a buffering effect when the first force transmission member 240 moves to lift the vibrating plate 250, preventing excessive expansion of the first expansion member 230 and thus excessive movement of the vibrating plate 250. The movement of the vibrating plate 250 is kept within a controllable range by the first elastic element 320. In this embodiment, the first elastic element 320 can be elastic rubber or a compression spring; designers can choose the appropriate design based on actual needs, which will not be elaborated here. Furthermore, the lamp plate 100 also includes a support spring 520, one end of which is connected to the mounting assembly. The support spring 520 is connected to the base circuit board 120 at one end and to the other end at the other. Multiple support springs 520 are provided and evenly distributed on the side of the base circuit board 120 near the base plate 110. This allows the support springs 520 to provide a buffering effect when the vibrating plate 250 pushes the base circuit board 120, preventing excessive movement of the vibrating plate 250 and thus excessive vibration of the base circuit board 120. The vibration amplitude of the base circuit board 120 is kept within a controllable range by the support springs 520, preventing the LED beads 130 on the base circuit board 120 from jumping out of its range due to excessive vibration. In this embodiment, one end of the support spring 520 connected to the mounting assembly 200 is disposed on the first mounting magnetic block 300 or the second mounting magnetic block 310 to prevent the support spring 520 from directly contacting the vibrating plate 250 and restricting its movement.

[0037] The inventors also considered that although the above-mentioned structure enables the mass transfer and installation of the LED chips 130, the heat generated by the lamp board 100 and the base circuit board 120 during use after the LED chips 130 are installed may have a certain impact on the LED chips 130. Therefore, a new structure is needed to dissipate the heat generated by the lamp board 100 during operation, as described below:

[0038] As shown in Figures 1 and 2, the mounting assembly 200 further includes a first force-relieving plate 280 and a second force-transmitting member 290. The first force-relieving plate 280 is movably disposed within the main body 210. One end of the second force-transmitting member 290 is connected to the first expansion member 230, and the other end is connected to the first force-relieving plate 280. When the first expansion member 230 expands, it drives the second force-transmitting member 290 to move, thereby pushing the first force-relieving plate 280 connected to the second force-transmitting member 290. Furthermore, the first force-transmitting member 240 and the second force-transmitting member 290 are disposed opposite to each other, and the first force-relieving plate 280 is disposed opposite to the vibrating plate 250. A first buffer member is provided between the first force-relieving plate 280 and the main body 210. Specifically, after the LED 130 is installed, when the base circuit board 120 starts working, heat is conducted to the airflow circulation component 220 to heat the gas located in the heating chamber 221. The heated gas expands and enters the second chamber 225a of the second baffle 225 through the second intake channel 227, thus changing the second baffle 225 from its first state to its second state, i.e., connecting the second airflow channel 223 with the heating chamber 221. The expanded gas then passes through the second airflow channel 223, opening the second one-way valve 270 to enter the first expansion member 230, causing the first expansion member 230 to expand. The expanded first expansion member 230 then pushes up the second force transmission member 290, causing the second expansion member 230 to expand. The second force transmission member 290 moves towards the base plate 110 to push the first force-relieving plate 280 towards the base plate 110, thereby consuming the mechanical energy converted from heat. Subsequently, under the action of the first buffer member, the first force-relieving plate 280 moves away from the base plate 110 to push the second force transmission member 290 to squeeze the first expansion member 230, causing the first one-way valve 260 to open. The gas in the first expansion member 230 enters the first airflow channel 222, and the gas in the first airflow channel 222 enters the first chamber 224a of the first blocking member 224 from the first air inlet channel 226, so as to change the first blocking member 224 from the first state to the second state, that is, the first airflow channel 222 and the heating The chambers 221 are connected, and the gas re-enters the heating chamber 221 for heating. As most of the gas in the first expansion member 230 enters the heating chamber 221 through the first airflow channel 222, the first one-way valve 260 gradually closes, and the gas in the first chamber 224a re-enters the first airflow channel 222, so that the first blocking member 224 switches from the second state to the first state. This repeated airflow circulation causes the first pressure relief plate 280 to reciprocate towards and near the base plate 110, so as to convert the heat generated by the lamp board 100 and the base circuit board 120 during use into mechanical energy for consumption, which can control the temperature of the lamp board 100 during use to a certain extent.In this embodiment, the first buffer can be either elastic rubber or a compression spring; designers can choose the appropriate design based on actual needs, which will not be elaborated here. Two second force transmission components 290 are provided, with one end of each component mounted on the first expansion member 230 and the other end respectively mounted on the two ends of the first force-relieving plate 280 on the side away from the base plate 110, forming a triangular structure as shown in Figure 2. This allows the first force-relieving plate 280 to vibrate irregularly as the two second force transmission components 290 move.

[0039] The base circuit board 120 has multiple mounting slots 121, including a first slot and a second slot. The structure of the first slot is different from that of the second slot, as shown in Figure 3. The LED bead 130 includes a pixel layer 131, a planarization layer 132, a circuit layer 133, and a support connection layer 134 arranged sequentially. The support connection layer 134 has a first pin 135 corresponding to the first slot and a second pin 136 corresponding to the second slot. During the installation of the LED bead 130 on the lamp board 100, the LED bead 130 will gradually adjust its position when vibrating, so that the first pin 135 of the LED bead 130 mates with the first slot and the second pin 136 mates with the second slot, thus completing the installation of the LED bead 130. At this time, the LED bead 130 can be electrically connected to the base circuit board 120 through the first pin 135 and the second pin 136. This allows the LED bead 130 to be illuminated, enabling staff to visually determine whether the LED bead 130 is installed correctly. In this embodiment, an electromagnetic layer can be provided on the supporting connection layer 134, and an electromagnet is provided on the base circuit board 120. When the LED bead 130 is electrically connected to the base circuit board 120 through the first pin 135 and the second pin 136, the electromagnetic layer is energized to generate magnetism, which magnetically attracts the electromagnet on the base circuit board 120 to fix the LED bead 130 on the base circuit board 120. It should be noted that the pixel layer 131 may include R pixel area, G pixel area, B pixel area and W pixel area, or R pixel area, G pixel area and B pixel area. The specific structure of the pixel layer 131 can be designed by the designer according to the needs of the display device; this is only an example.

[0040] The inventors considered that during the assembly of the lamp beads 130 in the lamp board 100 of this application, the lamp beads 130 may still experience significant jumping or vibration, causing the lamp beads 130 to jump out of the range of the lamp board 100. Based on this consideration, the inventors improved the lamp board 100 of the above embodiment. As shown in FIG7, as the second embodiment of this application, which is an improvement of the first embodiment of this application, a lamp board 100 is disclosed. The lamp board 100 further includes a blocking component 400. The blocking component 400 is disposed on the base plate 110. The blocking component 400 includes a blocking member 410, a second expansion member 420, and a first lifting structure 430. The second expansion member 420 is fixed between the base plate 110 and the blocking member 410. One end of the first lifting structure 430 is connected to the second expansion member 420, and the other end abuts against the blocking member 410.

[0041] When the lamp chip 130 is installed on the lamp board 100, the base circuit board 120 generates heat during operation. This heat is conducted to the second expansion member 420 located between the blocking member 410 and the base plate 110, heating the gas inside the second expansion member 420. The heated gas expands, causing the second expansion member 420 to expand. The expanded second expansion member 420 pushes the first lifting structure 430 towards the blocking member 410, lifting the blocking member 410 so that it is higher than the lamp chip 130, thus blocking the lamp chip 130. To prevent the LED bead 130 from jumping out of the area of ​​the lamp board 100 due to large jumping or vibration, thus causing the installation failure of the LED bead 130; after the LED bead 130 is installed on the base circuit board 120, a strong adhesive is applied to the blocking member 410, and the glass substrate 600 is placed on the blocking member 410 and the LED bead 130 to compress the blocking member 410 and the LED bead 130 to complete the installation; wherein, the strong adhesive can be acrylic pressure-sensitive adhesive, and the second expansion member 420 is made of a high temperature resistant and elastic deformable material, such as nitrile rubber or styrene-butadiene rubber.

[0042] Considering that the heat generated by the lamp board 100 and the base circuit board 120 during use after the lamp bead 130 is installed may have a certain impact on the lamp bead 130, a new structure is needed to dissipate the heat generated by the lamp board 100 during operation. Therefore, the blocking assembly 400 is further improved. The blocking assembly 400 also includes a second force lifting structure 440 and a second force relief plate 450. The second force relief plate 450 is movably disposed on the base plate 110. One end of the second force lifting structure 440 is connected to the second... The expansion member 420 is connected at one end and the other end is connected to the second force-relieving plate 450. The second force-lifting structure 440 is symmetrically arranged with the first force-lifting structure 430. A second buffer member is provided on the side of the second force-relieving plate 450 near the base plate 110. When the base circuit board 120 operates and generates heat, the heat is conducted to the second expansion member 420 to heat the gas inside the second expansion member 420. The gas expands due to the heat, causing the second expansion member 420 to expand. After the lamp bead 130 is installed, it will be installed on the lamp board 100. The glass substrate 600 presses the lamp bead 130 and the blocking member 410 together. Therefore, after the second expansion member 420 expands, it cannot push the first lifting structure 430, but can only push the second lifting structure 440 towards the base plate 110. This causes the second lifting structure 440 to push the second relief plate 450 towards the base plate 110. The second relief plate 450 moves towards the base plate 110 to compress the second buffer member. Subsequently, under the elastic force of the second buffer member, the second relief plate 450 moves away from the base plate 110. The second pressure relief plate 450 moves slightly, that is, under the action of the second buffer and the expanding second expansion member 420, it forms a reciprocating motion in the direction of approaching or moving away from the base plate 110, so as to consume the mechanical energy converted from the heat generated by the lamp bead 130 and the base circuit board 120 during operation, and can control the temperature of the lamp board 100 during use to a certain extent. In this embodiment, the second buffer can be elastic rubber or a compression spring. Designers can choose to design according to actual needs, which will not be elaborated here.

[0043] Furthermore, in order to fix the blocking member 410 to the base plate 110 after the lamp bead 130 is installed, the lamp plate 100 also includes a strong fixing member 510. The strong fixing member 510 is disposed between the base plate 110 and the blocking member 410 to fix the blocking member 410. Before the lamp bead 130 is installed, the strong fixing member 510 does not fix the base plate 110 to the blocking member 410. Only after the lamp bead 130 is installed is the strong fixing member 510 used to fix the blocking member 410 to the base plate 110 to prevent the second expansion member 42 from expanding. After expansion, the first lifting structure 430 is pushed, causing the blocking member 410 to move. In this embodiment, the strong fixing member 510 can use strong neodymium magnets with opposite polarities. One strong neodymium magnet is installed on the base plate 110 and the blocking member 410 respectively. After the lamp bead 130 is installed, the two strong neodymium magnets are magnetically connected to achieve strong fixing. Of course, designers can also use other fixing structures to fix the blocking member 410 and the base plate 110, as long as it is ensured that the blocking member 410 and the base plate 110 do not move. This will not be elaborated here.

[0044] As shown in Figure 8, as a third embodiment of this application, a display device 900 is disclosed. The display device 900 includes a driving circuit 800 and a display panel 700. The display panel 700 includes a glass substrate 600 and a lamp board 100 as described in the above embodiment. The driving circuit 800 is used to drive the display panel 700. The display device of this embodiment, by setting the structure of the mounting components, can realize the mass transfer and mounting of lamp beads through the structure of the lamp board itself, without the need to set an additional transfer mechanism to perform mass transfer of lamp beads. This reduces the requirements of the mass transfer process of Micro-LED and improves the mass transfer efficiency. In addition, it can convert the waste heat generated in the lamp board into the mass transfer and mounting of lamp beads for use, converting heat into mechanical energy for use, which saves production costs to a certain extent and has broad application prospects.
