Description

Technical Field

[0001] The invention relates to the technical field of LED display screens, in particular to an LED display screen with quantum dot luminescent materials capable of preventing light crosstalk. Background Art

[0002] With the rapid development of VR / AR industry, displays suitable for VR / AR have entered a period of rapid growth. Large-scale VR devices need to rely on LED displays to improve people's viewing experience. However, the optical crosstalk between pixels of the display module of the LED display has become particularly serious. In the existing technology, a reflective layer is generally grown outside the LED pixels to reduce and alleviate it, so as to improve people's use effect.

[0003] According to a publicly disclosed Micro-LED display screen and its manufacturing method (Announcement No.: CN111490061A), in the above application, the light absorption phenomenon of the quantum dot luminescent material layer can be effectively reduced, the light crosstalk can be eliminated, and the light output efficiency can be improved.

[0004] However, in actual use of the above-mentioned equipment, the light crosstalk protection of the LED display is achieved by using quantum dot luminescent materials, and the quantum dot luminescent materials are arranged between the LED display module and the display. As the operating time of the LED display module increases, the temperature inside the LED display is also constantly increasing, and excessively high operating environment temperature will greatly reduce the service life and operating stability of the quantum dot luminescent materials, thereby reducing the use effect of the LED display. Traditional cooling methods generally use 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, thereby limiting the cooling speed inside the LED display.

In addition, the number of fans 2 is set to two groups, and the two groups of fans 2 pass through the inner and outer cavities of the shell 1 to improve the heat dissipation performance of the internal cavity of the shell 1.

[0034] In addition, an arc groove compatible with the circulation pipe 5 is opened on the back of the LED display module 3, and the diameter of the arc groove is set to be the same as the diameter of the circulation pipe 5, so that when the circulation pipe 5 is embedded and installed in the arc groove, half of its volume is exposed outside the LED display module 3, and the interior of the circulation pipe 5 is filled with cooling water, and the cooling water flows continuously under the drive of the circulation pump 4, and cooperates with the setting of the fan 2 to achieve continuous cooling of the heat generated on the LED display module 3 to ensure the use effect of the LED display module 3. At the same time, the number of interactive components 6 is set to multiple groups, and the multiple groups 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 obtain a better heat exchange effect to improve the cooling efficiency of the LED display module 3.

[0035] Specifically, the circulation pipeline 5 is provided with multiple sections, and the multiple sections of the circulation pipeline 5 are respectively connected between multiple groups of interactive cylinders 61 and the circulation pump 4, so that the multiple groups of interactive cylinders 61 and the circulation pump 4 can be connected end to end to form a complete cooling closed loop. At the same time, the number of mounting rods 63 is provided with two groups, and the two groups 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. In addition, a circular hole with a diameter equal to the outer diameter of the fixing rod 64 is opened at the axis center of the sleeve 68, so that the sleeve 68 and the fixing rod 64 can be installed horizontally. The rods 64 can move relative to each other in the horizontal direction and rotate relative to each other. Specifically, there are three groups of round rods 66, and the three groups of round rods 66 are evenly distributed on the side wall of the impeller 65 in a circular array, and a circular hole with a diameter matching the outer diameter of the round rods 66 is opened at the end of the sleeve 68, and the two ends of the reset spring 67 are respectively fixedly connected to the inner wall of the end of the circular hole and the outer wall of the end of the round rods 66, so that when the impeller 65 rotates, it will drive the sleeve 68 to rotate synchronously through the transmission of the round rods 66, and at the same time will not affect the movement trend of the sleeve 68 in the horizontal direction.

[0036] In addition, when the circulating pump 4 drives 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, and then the sleeve 68 is driven by the round rod 66 to rotate synchronously on the outer surface of the fixed rod 64. At this time, the sleeve 68 is guided and restricted by the convex ball 610 and the wave groove 69, and cooperates with the reset spring 67, so that the sleeve 68 will also perform a small reciprocating motion in the horizontal direction while rotating. At the same time, the number of spiral blades 611 is arranged in multiple groups, and the multiple groups of spiral blades 611 are evenly distributed on the arc-shaped outer surface of the sleeve 68 in a spiral array, and 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 close to the interaction cavity 62 and away from the center, so as to promote the internal and external temperatures of the cooling water in the circulating pipe 5 to be more balanced and stable, thereby improving the cooling efficiency of the cooling water in the circulating pipe 5 on the LED display module 3, and ensuring the use effect of the quantum dot luminescent material.

[0037] In an embodiment of the present invention, a swing assembly 7 is provided on the arcuate outer surface of the sleeve 68, and the swing assembly 7 includes a transmission groove 71, which is opened on the arcuate outer wall of the sleeve 68, and a rotating ring 72 is rotatably installed on the inner surface of the transmission groove 71, and an inner tooth pattern 73 is opened on the arcuate inner surface of the transmission groove 71, and a small gear 74 is rotatably installed on the side wall of the transmission groove 71, and an outer tooth pattern 75 is opened on the arcuate inner surface of the rotating ring 72, and a rotating rod 76 is rotatably installed on the arcuate outer wall of the rotating ring 72, and a swing leaf 77 is fixedly installed on the end of the rotating rod 76, and a spiral spring 78 is sleeved on the arcuate outer wall of the rotating ring 72.

[0038] Specifically, there are multiple groups of swing components 7, and the multiple groups of swing components 7 are evenly distributed in a linear array on the arc-shaped outer wall of the sleeve 68, and the swing components 7 are arranged in the gaps between the multiple groups of spiral blades 611 to avoid affecting the use effect of the spiral blades 611. At the same time, the pinion 74 meshes with the inner tooth pattern 73 and the outer tooth pattern 75 to realize transmission, and there are multiple groups of pinion gears 74, and the multiple groups of pinion gears 74 are evenly distributed in a circular array inside the transmission groove 71, so that the inner tooth pattern 73, the pinion gear 74 and the outer tooth pattern 75 form a planetary gear transmission structure. When the sleeve 68 rotates with the outer surface of the fixed rod 64, the outer tooth pattern 75 and the rotating ring 72 rotate on the outer surface of the sleeve 68 at a speed lower than the speed of the sleeve 68 through the transmission of the pinion gear 74, thereby forming a speed difference between the rotating ring 72 and the spiral blade 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, so that the rotating rod 76 always has a movement tendency of reverse rotation to achieve reset when rotating. Therefore, when the rotating ring 72 rotates inside the interactive cavity 62, it is affected by the flow of cooling water, so that the swing leaf 77 will undergo an approximately disordered relative deflection. At the same time, under the elastic force of the spiral spring 78, it will not remain stationary, but will swing back and forth all the time, thereby enabling the cooling water in the interactive cavity 62 to perform more efficient heat exchange, thereby improving the cooling efficiency of the entire circulating cooling component for the LED display module 3.

[0040] Furthermore, a spoiler assembly 8 is provided inside the swing leaf 77, and the spoiler assembly 8 includes a swing cavity 81, which is opened inside the swing leaf 77, and a transmission rod 82 is rotatably installed on the inner surface of the swing cavity 81, and a spoiler 83 is passed through and fixedly installed on the transmission rod 82. A coil spring 84 is sleeved on the arc-shaped outer wall of the transmission rod 82, and convex belts 85 are provided on the left and right outer walls of the spoiler 83.

[0041] It is worth noting that transmission holes with a diameter larger than the outer diameter of the coil spring 84 are opened on the inner walls on the upper and lower sides of the swing cavity 81, and 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, so that under the elastic force of the coil spring 84, when the transmission rod 82 drives the spoiler 83 to rotate, it always has a movement tendency of reverse rotation to achieve reset, and in the initial state setting, the spoiler 83 and the swing leaf 77 are set in an X shape. Furthermore, the cross-section of the convex belt 85 is set to be triangular, and the convex belt 85 is provided with three groups, and the three groups of convex belts 85 are arranged at equal intervals on the side of the spoiler 83, and the two groups of convex belts 85 away from the center of the spoiler 83 are provided with notches, thereby enhancing the spoiler 83 When the transmission rod 82 rotates, the spoiler effect on the cooling water in the interactive cavity 62 is enhanced, and the heat exchange of the cooling water in the interactive cavity 62 is promoted, ensuring that the LED display module 3 is always at a safe working temperature, and improving the use effect of the device.

[0042] In the present invention, when the LED display screen is working, the fan 2 and the circulation pump 4 on the back of the shell 1 are started synchronously to promote the continuous circulation of cooling water in the closed channel of the circulation pipe 5 and the interactive cylinder 61, so that the heat generated by the LED display module 3 when working is continuously taken away by the flow of cooling water, and the fan 2 is cooperated to dissipate heat, so as to ensure that the LED display module 3 is always at a more suitable working temperature, and the display effect of the quantum dot luminescent material is ensured. At the same time, by arranging an interactive component 6 in the interactive cylinder 61, when the circulation pump 4 drives the cooling water to flow in the circulation pipe 5, the impeller 65 is driven to rotate on the outer surface of the fixed rod 64, and then ... Driven by 66, the sleeve 68 is prompted to rotate synchronously on the outer surface of the fixed rod 64. At this time, it is guided and restricted by the convex ball 610 and the wave groove 69, and cooperates with the reset spring 67, so that the sleeve 68 will also perform a small reciprocating motion in the horizontal direction while rotating, and cooperates with the multiple sets of spiral blades 611 set on the outer surface of the sleeve 68 to promote the interaction of the cooling water at the center of the interaction cavity 62 and the cooling water close to the interaction cavity 62 and away from the center, so as to make the internal and external temperatures 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 on the LED display module 3, and ensuring the use effect of the quantum dot luminescent material.

[0043] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
