Description

Technical Field

[0001] This invention relates to the field of LED display technology, specifically to an LED display with quantum dot luminescent material that is resistant to light crosstalk. Background Technology

[0002] With the rapid development of the VR / AR industry, displays suitable for VR / AR have ushered in a period of rapid growth. Large VR devices need to rely on LED displays to improve people's viewing experience. However, the optical crosstalk phenomenon between the pixels of the LED display module has become particularly serious. In existing technologies, a reflective layer is generally grown on the outside of the LED pixels to reduce and alleviate the problem, thereby improving the user experience.

[0003] According to a Micro-LED display screen and its manufacturing method disclosed in the public notice (Announcement No.: CN111490061A), the above application can effectively reduce the light absorption phenomenon of the quantum dot light-emitting material layer, eliminate light crosstalk, and improve light extraction efficiency.

[0004] However, in actual use, the aforementioned devices rely on quantum dot luminescent materials to prevent crosstalk in LED displays. These quantum dot luminescent materials are placed between the LED display module and the display screen. As the operating time of the LED display module increases, the temperature inside the LED display screen also rises continuously. Excessively high operating temperatures significantly reduce the lifespan and operational stability of the quantum dot luminescent materials, thereby diminishing the performance of the LED display screen. Traditional cooling methods typically employ air cooling or water cooling, but the contact efficiency between the quantum dot luminescent materials installed on the LED display module and the cooling medium is limited, thus restricting the cooling rate within the LED display screen. Therefore, we propose an LED display screen with quantum dot luminescent materials that can prevent crosstalk. Summary of the Invention

[0005] The purpose of this invention is to provide an LED display screen with quantum dot luminescent material that is resistant to light crosstalk, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an LED display screen with quantum dot luminescent material that is resistant to light crosstalk, comprising a housing, a fan fixedly mounted on the inner wall of the back of the housing, an LED display module fixedly mounted on the inner wall of the housing, a circulation pump fixedly mounted on the inner wall of the bottom of the housing, a circulation pipe fixedly connected to the output end of the circulation pump, and an interactive component disposed on the back of the LED display module, the interactive component comprising:

[0007] An interactive tube is fixedly installed on the back of an LED display module. An interactive cavity is formed on the inner wall of the interactive tube. An installation rod is fixedly installed on the inner wall of the interactive cavity. A ring is set at the center of the installation rod. A fixing rod is fixedly installed on the inner wall of the ring. An impeller is rotatably installed on the arc-shaped outer wall of one end of the fixing rod.

[0008] A round rod is fixedly connected to the side wall of the impeller. A return spring is fixedly connected to the end of the round rod away from the impeller. A sleeve is fitted on the outer wall of the fixed rod. A wave groove is formed on the arc-shaped outer wall of the fixed rod. A convex ball is fixedly installed on the inner wall of the sleeve. The convex ball is located inside the wave groove. A helical blade is fixedly installed on the arc-shaped outer wall of the sleeve.

[0009] Preferably, the back of the LED display module is provided with an arc-shaped groove adapted to the circulation pipe, and the diameter of the arc-shaped groove is the same as the diameter of the circulation pipe, so that when the circulation pipe is embedded in the interior of the arc-shaped groove, half of its volume is exposed outside the LED display module, and the interior of the circulation pipe is filled with cooling water, so that the continuously flowing cooling water can cool the LED display module.

[0010] Preferably, the number of the round rods is set to three sets, and the three sets of round rods are evenly distributed in a circumferential array on the side wall of the impeller. The end of the sleeve is provided with a round hole with a diameter that matches the outer diameter of the round rod. The two ends of the return spring are fixedly connected to the inner wall of the end of the round hole and the outer wall of the end of the round rod, respectively, so that when the impeller rotates, it will drive the sleeve to rotate synchronously through the transmission of the round rod.

[0011] Preferably, the number of spiral blades is set to multiple sets, and the multiple sets of spiral blades are evenly distributed in a spiral array on the arc-shaped outer surface of the sleeve. Then, the movement of the sleeve drives the spiral blades to reciprocate in the interaction cavity, so as to promote the interaction between the cooling water at the center of the interaction cavity and the cooling water near the interaction cavity away from the center.

[0012] Preferably, a swing assembly is provided on the arc-shaped outer surface of the sleeve. The swing assembly includes a transmission groove, which is formed on the arc-shaped outer wall of the sleeve. A rotating ring is rotatably mounted on the inner surface of the transmission groove. Internal teeth are formed on the arc-shaped inner surface of the transmission groove. A small gear is rotatably mounted on the side wall of the transmission groove. External teeth are formed on the arc-shaped inner surface of the rotating ring. A rotating rod is rotatably mounted on the arc-shaped outer wall of the rotating ring. A swing blade is fixedly mounted at the end of the rotating rod. A spiral spring is sleeved on the arc-shaped outer wall of the rotating ring.

[0013] Preferably, the number of the oscillating components is set to multiple sets, and the multiple sets of oscillating components are evenly distributed in a linear array on the arc-shaped outer wall of the sleeve. Furthermore, the oscillating components are located at the gaps between the multiple sets of spiral blades to avoid affecting the performance of the spiral blades.

[0014] Preferably, the outer arc-shaped wall of the rotating ring is provided with a circular groove with a diameter larger than the outer diameter of the spiral spring, and the two ends of the spiral spring are respectively fixedly connected to the bottom inner wall of the circular groove and the outer arc-shaped wall of the rotating rod, so that the rotating rod always has a tendency to rotate in the opposite direction to achieve reset when rotating.

[0015] Preferably, the interior of the oscillating blade is provided with a turbulence assembly, the turbulence assembly including an oscillating cavity, the oscillating cavity being opened inside the oscillating blade, a transmission rod being rotatably mounted on the inner surface of the oscillating cavity, a turbulence plate being fixedly mounted through the transmission rod, a coil spring being sleeved on the arc-shaped outer wall of the transmission rod, and raised strips being provided on the left and right outer walls of the turbulence plate.

[0016] Preferably, the upper and lower inner walls of the swing cavity are provided with transmission holes with a diameter larger than the outer diameter of the coil spring, and the two ends of the coil spring are fixedly connected to the arc-shaped outer wall of the transmission rod and the bottom inner wall of the transmission hole, respectively. Thus, under the elastic force of the coil spring, when the transmission rod drives the spoiler to rotate, it always has a tendency to rotate in the opposite direction to achieve reset.

[0017] Preferably, the spoiler and the oscillating blade are arranged in an X-shape, the cross-section of the convex strip is triangular, and there are three sets of convex strips. The three sets of convex strips are evenly spaced on the side of the spoiler, and the two sets of convex strips located away from the center of the spoiler are provided with notches, thereby improving the turbulence effect of the spoiler on the cooling water in the interactive cavity when it rotates with the transmission rod.

[0018] Compared with the prior art, the present invention provides an LED display screen with quantum dot luminescent material that is resistant to light crosstalk, which has the following beneficial effects:

[0019] 1. This LED display screen with quantum dot luminescent material and anti-light crosstalk works by having a circulating pump drive cooling water to flow through the circulating pipe. This causes the impeller to rotate on the outer surface of the fixed rod. Guided and restricted by the convex ball and the wave groove, and with the help of the return spring, the sleeve also makes a small reciprocating motion in the horizontal direction while rotating. This allows multiple sets of spiral blades to cause the cooling water at the center of the interaction cavity to interact with the cooling water near the center of the interaction cavity. This makes the internal and external temperatures of the cooling water in the circulating pipe more balanced and stable, thereby improving the cooling efficiency of the cooling water in the circulating pipe for the LED display module and ensuring the effectiveness of the quantum dot luminescent material.

[0020] 2. This LED display screen with quantum dot luminescent material and anti-light crosstalk is equipped with a swinging component. When the rotating ring rotates inside the interaction cavity, it is affected by the flow of cooling water, causing the swinging blades to undergo a near-random relative deflection. At the same time, under the elastic force of the spiral spring, it does not remain stationary but continues to swing back and forth. This allows the cooling water in the interaction cavity to carry out more efficient heat exchange, thereby improving the cooling efficiency of the entire circulating cooling component for the LED display module.

[0021] 3. This LED display screen with quantum dot luminescent material that is resistant to light crosstalk has an X-shaped baffle inside the swing blade, which, together with the convex strips on both sides, enhances the turbulence effect of the baffle on the cooling water in the interaction cavity when it rotates with the transmission rod. This promotes the heat exchange of the cooling water in the interaction cavity, ensures that the LED display module is always at a safe operating temperature, and improves the performance of the device.

[0031] like Figures 1-8 As shown, the present invention provides a technical solution: an LED display screen with quantum dot luminescent material that is resistant to light crosstalk, including a housing 1, a fan 2 fixedly installed on the inner wall of the back of the housing 1, an LED display module 3 fixedly installed on the inner wall of the housing 1, a circulation pump 4 fixedly installed on the inner wall of the bottom of the housing 1, a circulation pipe 5 fixedly connected to the output end of the circulation pump 4, and an interactive component 6 provided on the back of the LED display module 3. The interactive component 6 includes an interactive cylinder 61, an interactive cavity 62, a mounting rod 63, a fixing rod 64, an impeller 65, a round rod 66, a reset spring 67, a sleeve 68, a wave groove 69, a convex ball 610, and a spiral blade 611.

[0032] In one embodiment of the present invention, an interactive cylinder 61 is fixedly installed on the back of an LED display module 3. An interactive cavity 62 is formed on the inner wall of the interactive cylinder 61. An installation rod 63 is fixedly installed on the inner wall of the interactive cavity 62. A ring is provided at the center of the installation rod 63. A fixing rod 64 is fixedly installed on the inner wall of the ring. An impeller 65 is rotatably installed on the arc-shaped outer wall of one end of the fixing rod 64. A round rod 66 is fixedly connected to the side wall of the impeller 65. A return spring 67 is fixedly connected to the end of the round rod 66 away from the impeller 65. A sleeve 68 is sleeved on the outer wall of the fixing rod 64. A wave groove 69 is formed on the arc-shaped outer wall of the fixing rod 64. A convex ball 610 is fixedly installed on the inner wall of the sleeve 68. The convex ball 610 is disposed inside the wave groove 69. A spiral blade 611 is fixedly installed on the arc-shaped outer wall of the sleeve 68.

[0033] Furthermore, the housing 1 has an internal cavity for mounting the LED display module 3, and heat dissipation grooves are provided on the top and left and right outer walls of the housing 1 to ensure the internal heat dissipation performance of the LED display screen, thereby ensuring the display effect of the LED display module 3 on the image. A quantum dot light-emitting material layer is provided on the outer surface of the LED display module 3 away from the fan 2 to improve the display effect of the LED display module 3 on the image. The quantum dot light-emitting material reduces the light absorption of the quantum dot light-emitting material layer when the LED display module 3 is working, improves the light conversion efficiency, and reduces light crosstalk, ensuring the display effect of the LED display screen and improving the viewing experience. In addition, there are two sets of fans 2, and the two sets of fans 2 penetrate the inner and outer cavities of the housing 1 to improve the heat dissipation performance of the internal cavity of the housing 1.

[0034] In addition, an arc-shaped groove adapted to the circulation pipe 5 is provided on the back of the LED display module 3, and the diameter of the arc-shaped groove is the same as the diameter of the circulation pipe 5, so that when the circulation pipe 5 is embedded in the arc-shaped groove, half of its volume is exposed outside the LED display module 3. The circulation pipe 5 is filled with cooling water, and the cooling water flows continuously under the drive of the circulation pump 4. With the help of the fan 2, the heat generated on the LED display module 3 is continuously cooled to ensure the performance of the LED display module 3. At the same time, multiple sets of interactive components 6 are provided, and the multiple sets of interactive components 6 are evenly distributed in a linear array on the back of the LED display module 3, so that the cooling water in the circulation pipe 5 can achieve better heat exchange effect and improve the cooling efficiency of the LED display module 3.

[0035] Specifically, the circulation pipe 5 is provided in multiple sections, and these sections are connected to multiple sets of interactive cylinders 61 and circulating pumps 4, respectively, so that the multiple sets of interactive cylinders 61 and circulating pumps 4 can be connected end to end to form a complete cooling closed loop. Simultaneously, two sets of mounting rods 63 are provided, and the two sets of mounting rods 63 are vertically mirrored on the left and right sides of the vertical central axis of the interactive cavity 62, so that the fixing rod 64 can be horizontally installed inside the interactive cavity 62. Furthermore, a circular hole with a diameter matching the outer diameter of the fixing rod 64 is provided at the axis of the sleeve 68, so that the sleeve 68 and the fixing rod 64 can be connected. The fixed rods 64 can move relative to each other in the horizontal direction and rotate relative to each other. Specifically, there are three sets of round rods 66, and the three sets of round rods 66 are evenly distributed in a circumferential array on the side wall of the impeller 65. The end of the sleeve 68 is provided with a round hole with a diameter that matches the outer diameter of the round rod 66. The two ends of the return spring 67 are fixedly connected to the inner wall of the end of the round hole and the outer wall of the end of the round rod 66, respectively. This allows the sleeve 68 to rotate synchronously through the transmission of the round rods 66 when the impeller 65 rotates, without affecting the horizontal movement trend of the sleeve 68.

[0036] In addition, during the process of the circulating pump 4 driving the cooling water to flow in the circulating pipe 5, the impeller 65 is driven to rotate on the outer surface of the fixed rod 64. Then, under the drive of the round rod 66, the sleeve 68 is driven to rotate synchronously on the outer surface of the fixed rod 64. At this time, guided and restricted by the convex ball 610 and the wave groove 69, and with the help of the return spring 67, the sleeve 68 will also make a small reciprocating motion in the horizontal direction while rotating. At the same time, there are multiple sets of spiral blades 611, and the multiple sets of spiral blades 611 are evenly distributed in a spiral array on the arc-shaped outer surface of the sleeve 68. Then, the movement of the sleeve 68 drives the spiral blades 611 to reciprocate in the interaction cavity 62, so as to promote the interaction between the cooling water at the center of the interaction cavity 62 and the cooling water near the center of the interaction cavity 62, so as to make the internal and external temperature of the cooling water in the circulating pipe 5 more balanced and stable, thereby improving the cooling efficiency of the cooling water in the circulating pipe 5 to the LED display module 3 and ensuring the effect of quantum dot light-emitting material.

[0037] In an embodiment of the present invention, a swing assembly 7 is provided on the arc-shaped outer surface of the sleeve 68. The swing assembly 7 includes a transmission groove 71, which is formed on the arc-shaped outer wall of the sleeve 68. A rotating ring 72 is rotatably mounted on the inner surface of the transmission groove 71. An internal tooth pattern 73 is formed on the arc-shaped inner surface of the transmission groove 71. A small gear 74 is rotatably mounted on the side wall of the transmission groove 71. An external tooth pattern 75 is formed on the arc-shaped inner surface of the rotating ring 72. A rotating rod 76 is rotatably mounted on the arc-shaped outer wall of the rotating ring 72. A swing blade 77 is fixedly mounted at the end of the rotating rod 76. A spiral spring 78 is sleeved on the arc-shaped outer wall of the rotating ring 72.

[0038] Specifically, multiple sets of oscillating components 7 are arranged in a linear array and evenly distributed on the arc-shaped outer wall of the sleeve 68. The oscillating components 7 are positioned at the gaps between multiple sets of spiral blades 611 to avoid affecting the performance of the spiral blades 611. Meanwhile, the pinion 74 meshes with the internal tooth pattern 73 and the external tooth pattern 75 to achieve transmission. Multiple sets of pinion 74 are arranged in a circumferential array and evenly distributed inside the transmission groove 71. This forms a planetary gear transmission structure with the internal tooth pattern 73, the pinion 74, and the external tooth pattern 75. When the sleeve 68 rotates on the outer surface of the fixed rod 64, the external tooth pattern 75 and the rotating ring 72 rotate on the outer surface of the sleeve 68 at a lower speed than the sleeve 68 through the transmission of the pinion 74. This creates a speed difference between the rotating ring 72 and the spiral blades 611.

[0039] In addition, a circular groove with a diameter larger than the outer diameter of the spiral spring 78 is provided on the arc-shaped outer wall of the rotating ring 72, and the two ends of the spiral spring 78 are fixedly connected to the bottom inner wall of the circular groove and the arc-shaped outer wall of the rotating rod 76, respectively. This makes the rotating rod 76 always have a tendency to rotate in the opposite direction to achieve a reset when rotating. As a result, when the rotating ring 72 rotates inside the interaction cavity 62, it is affected by the flow of cooling water, causing the oscillating blade 77 to undergo a near-random relative deflection. At the same time, under the elastic force of the spiral spring 78, it will not remain stationary, but will continue to oscillate back and forth. This allows the cooling water in the interaction cavity 62 to carry out more efficient heat exchange, improving the cooling efficiency of the entire circulating cooling assembly for the LED display module 3.

[0040] Furthermore, the interior of the oscillating blade 77 is provided with a turbulence assembly 8, which includes an oscillating cavity 81. The oscillating cavity 81 is opened inside the oscillating blade 77. A transmission rod 82 is rotatably mounted on the inner surface of the oscillating cavity 81. A turbulence plate 83 is fixedly mounted through the transmission rod 82. A coil spring 84 is sleeved on the arc-shaped outer wall of the transmission rod 82. Protruding strips 85 are provided on the outer walls of the left and right sides of the turbulence plate 83.

[0041] It is worth noting that the upper and lower inner walls of the swing cavity 81 are provided with transmission holes with a diameter larger than the outer diameter of the coil spring 84. The two ends of the coil spring 84 are fixedly connected to the arc-shaped outer wall of the transmission rod 82 and the bottom inner wall of the transmission hole, respectively. Thus, under the elastic force of the coil spring 84, when the transmission rod 82 drives the spoiler 83 to rotate, it always has a tendency to rotate in the opposite direction to achieve a reset. In the initial setting, the spoiler 83 and the swing blade 77 are arranged in an X shape. Furthermore, the cross-section of the convex strip 85 is set in a triangular shape, and there are three sets of convex strips 85. The three sets of convex strips 85 are equally spaced on the side of the spoiler 83, and the two sets of convex strips 85 located away from the center of the spoiler 83 are provided with notches. This improves the turbulence effect of the spoiler 83 on the cooling water in the interaction cavity 62 when it rotates with the transmission rod 82, promotes the heat exchange of the cooling water in the interaction cavity 62, ensures that the LED display module 3 is always at a safe operating temperature, and improves the performance of the device.

[0042] In this invention, when the LED display screen is working, the fan 2 and the circulation pump 4 on the back of the housing 1 are simultaneously activated to cause the cooling water to continuously circulate within the closed channel of the circulation pipe 5 and the interactive cylinder 61. This continuous flow of cooling water removes the heat generated by the LED display module 3 during operation, working in conjunction with the fan 2 to dissipate heat and ensure that the LED display module 3 remains at a suitable operating temperature, thus guaranteeing the display effect of the quantum dot luminescent material. Simultaneously, by providing an interactive component 6 within the interactive cylinder 61, the impeller 65 rotates on the outer surface of the fixed rod 64 as the circulation pump 4 drives the cooling water to flow within the circulation pipe 5. Driven by 66, the sleeve 68 rotates synchronously on the outer surface of the fixed rod 64. At this time, guided and restricted by the convex ball 610 and the wave groove 69, and with the help of the return spring 67, the sleeve 68 also makes a small reciprocating motion in the horizontal direction while rotating. With the help of the multiple sets of spiral blades 611 set on the outer surface of the sleeve 68, the cooling water at the center of the interaction cavity 62 and the cooling water near the center of the interaction cavity 62 interact, so as to make the internal and external temperature of the cooling water in the circulation pipe 5 more balanced and stable, thereby improving the cooling efficiency of the cooling water in the circulation pipe 5 to the LED display module 3 and ensuring the effect of quantum dot light-emitting material.

[0043] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
