Description

Technical Field

[0001] This invention relates to the field of LED display equipment technology, and more specifically, to an LED full-color display enhancement device. Background Technology

[0002] LED Full-Color Display Screen: LED is the abbreviation for Light Emitting Diode. It is a display method that controls RGB semiconductor light-emitting diodes. It generally consists of many RGB three-color light-emitting diodes, with each pixel group having its own RGB diode. Different colors are displayed by the on / off state of each group of pixels. It is used to display various information such as text, graphics, images, animations, market data, videos, and recorded signals. Many existing LED full-color display devices on the market incorporate LED full-color display enhancement devices. These devices or systems are used to improve the performance of LED displays, with main functions including color optimization, brightness adjustment, and image processing. Patent CN106713713 A discloses an LED full-color display screen and its augmented reality editing and playback method, including an LED full-color display screen body, an LED full-color display screen receiving card, a camera or webcam, a video processor or video processing card, an LED full-color display screen transmitting card, a control computer, and a control system installed in the control computer. This provides viewers with a video image combining the real-time video scene behind the LED full-color display screen and virtual video images, enhancing the augmented reality editing and playback effect of the LED full-color display screen.

[0003] However, the existing LED full-color display equipment on the market has a relatively simple structure and technology. The display equipment does not have a reflective liquid bladder structure and does not have the ability to adjust the reflectivity of the LED display. This is not conducive to the enhancement and adjustment of the LED full-color display. Traditional LED full-color display equipment does not have the ability to adaptively enhance the LED full-color display according to the visual perception. In addition, the disassembly and maintenance of traditional LED display equipment is relatively inconvenient in the later stage, and the heat dissipation effect is generally poor, which affects the service life of the LED display equipment.

[0004] Therefore, it is meaningful for us to make improvements and propose an LED full-color display enhancement device. Summary of the Invention

[0018] As a preferred technical solution of this application, the liquid tank is filled with coolant, and an injection port is installed through the top side outer wall of the liquid tank.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In the scheme of this application:

[0021] This LED full-color display enhancement device sets up a reflective liquid bladder structure between the LED display screen and the circuit board. The reflective coating on the concave wall of the reflective liquid bladder can reflect the display light of the LED display screen, enhancing the full-color display effect of the LED. By controlling the amount of liquid injected into the reflective liquid bladder, the curvature of the concave wall can be adjusted, thereby adjusting the reflectivity, which is beneficial for the adjustment of LED full-color display enhancement. The reflective liquid bladder structure between the LED display screen and the circuit board also plays a role in shock absorption and heat absorption for the LED display screen and the circuit board.

[0022] This LED full-color display enhancement device uses an eye-tracking camera to monitor the user's eyes while the user is viewing the LED display screen. The camera monitors and acquires pupil data, analyzes the pupil data, identifies the user's vision problems, and uses an algorithm to adaptively optimize and enhance the LED display parameters according to the corresponding vision problems, thus achieving adaptive enhancement of the LED full-color display.

[0023] By setting up the snap-fit ​​assembly components, the snap-fit ​​assembly of the LED display housing can be achieved. Under the action of the second spring, the pressure ring moves down along the insertion tube. The pressure ring presses against the outer wall of the four corners of the circuit board, so that the circuit board, the reflective liquid bladder plate and the LED display screen are tightly attached, ensuring the tight assembly of the LED full-color display enhancement device, and facilitating the disassembly of the LED display structure, which is beneficial to the inspection and maintenance of the LED full-color display enhancement device.

[0024] By setting up a sealed water-cooling heat dissipation component, the liquid pump is controlled to pump coolant from the liquid tank and input it into the liquid bladder sealing ring through the pump pipe. The liquid bladder sealing ring expands after being filled with liquid to ensure the sealing of the LED display assembly shell, preventing dust and moisture intrusion, improving the lifespan of the LED display, and solving the problem of light leakage affecting display quality in traditional LED displays. When the hydraulic pressure in the liquid bladder sealing ring reaches the threshold of the micro-controlled electromagnetic pressure relief valve, coolant is input into the reflective liquid bladder plate. By adjusting the threshold of the micro-controlled electromagnetic pressure relief valve, the curvature of the concave wall of the reflective liquid bladder plate can be adjusted, thereby adjusting the reflectivity. During operation, the coolant in the reflective liquid bladder plate and the liquid bladder sealing ring absorbs the heat generated by the LED display. When the hydraulic pressure in the liquid bladder sealing ring reaches the threshold of the constant pressure relief valve, the coolant that has absorbed heat is discharged through the return pipe. The coolant exchanges heat with the outside air through the radiator, dissipating the heat absorbed by the coolant. The cooled coolant then flows back into the liquid tank through the return pipe, realizing the circulating liquid cooling heat dissipation of the LED full-color display equipment.

[0043] The following is in conjunction with the appendix Figure 1-8 The present invention is further illustrated by the embodiments:

[0044] In this embodiment, as Figure 1-8As shown, an LED full-color display enhancement device includes an LED display body 1. A rear cover 2 and a front cover 3 are respectively disposed on the outer walls of both sides of the LED display body 1. An LED display screen 4 is embedded in the bottom inner wall of the front cover 3. A circuit board 5 is disposed on the inner wall of the middle part of the LED display body 1. A reflective liquid bladder plate 6 is disposed on the inner wall between the LED display screen 4 and the circuit board 5. The LED display screen 4 and the circuit board 5 are electrically connected by a ribbon cable. One side of the outer wall of the reflective liquid bladder plate 6 is concave conical, and a reflective coating 7 is coated on the concave outer wall. A snap-fit ​​assembly 8 is disposed at the connection between the rear cover 2 and the front cover 3. One side of the outer wall of the rear cover 2... Equipped with a sealed water-cooled heat dissipation component 9, this LED full-color display enhancement device, based on the traditional LED display structure, sets up a reflective liquid bladder plate 6 structure between the LED display screen 4 and the circuit board 5. The reflective coating 7 on the concave wall of the reflective liquid bladder plate 6 can reflect the display light of the LED display screen 4, enhancing the LED full-color display effect. By controlling the amount of liquid injected into the reflective liquid bladder plate 6, the curvature of the concave wall can be adjusted, thereby achieving the adjustment of reflectivity, which is beneficial for the adjustment of LED full-color display enhancement. The setting of the reflective liquid bladder plate 6 structure between the LED display screen 4 and the circuit board 5 also plays a role in damping and absorbing heat for the LED display screen 4 and the circuit board 5.

[0045] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The snap-fit ​​assembly 8 includes insertion sleeves 801 distributed and fixed on the inner walls of the four corners of the bottom of the front cover 3. The outer walls of the circuit board 5 and the reflective liquid bladder plate 6 are respectively provided with through-holes 802. Insertion tubes 803 are fixedly connected to the inner walls of the four corners of the top of the rear cover 2. A connecting rod 804 is connected through the inside of the insertion tube 803. A limiting plate 805 is fitted and fixed to the outer wall of one end of the connecting rod 804 inside the insertion tube 803. The connecting rod 804 inside the insertion tube 803 is located on the outer wall below the limiting plate 805. The assembly includes a first spring 806, and locking blocks 807 fixed to the outer walls on both sides of the bottom end of the connecting rod 804. A handle 808 is fixed to the outer wall of one end of the connecting rod 804 that passes through the outer side of the rear cover 2. Slots 809 are provided on the inner walls on both sides of the top of the insertion sleeve 801, and an arc groove 810 is provided on the inner wall at the bottom end of the insertion sleeve 801, with the bottom end of the slot 809 penetrating inside the arc groove 810. Locking slots 811 are provided on the inner walls at the top of both ends of the arc groove 810. This LED full-color display enhancement device is used during the assembly of the LED display, such as... Figure 2As shown, the reflective liquid bladder plate 6 and the mounting holes 802 on the circuit board 5 are aligned and fitted onto the outer wall of the insert sleeve 801 inside the front cover 3. Then, the rear cover 2 is placed on top of the front cover 3, so that the insert tube 803 on the inner wall of the rear cover 2 is aligned and inserted into the insert sleeve 801. During the process, the handle 808 is rotated so that the locking block 807 at the end of the connecting rod 804 is aligned with the slot 809 on the insert sleeve 801. Then, the handle 808 is pressed, which drives the locking block 807 to move down through the connecting rod 804, so that the locking block 807 is inserted into the bottom of the slot 809. During the downward movement of the connecting rod 804, the limiting plate 805 will move down inside the insert tube 803. The first spring 806 is compressed and then the handle 808 drives the connecting rod 804 and the locking block 807 to rotate. The locking block 807 rotates along the arc groove 810 to the bottom of the locking groove 811. Then the handle 808 is released, and under the action of the first spring 806, the limiting plate 805 and the connecting rod 804 move upward, thereby driving the locking block 807 to move upward and engage in the locking groove 811. This realizes the locking and fixing of the insertion tube 803 into the insertion sleeve 801, realizing the assembly of the LED display. In the later stage, this structure can facilitate the disassembly of the LED display structure and is beneficial to the inspection and maintenance of the LED full-color display enhancement device.

[0046] Furthermore, grooves 11 are provided on the outer wall of the rear cover 2 below the handle 808. A second spring 12 and a retaining ring 13 are fitted on the outer wall of the top of the insertion tube 803. The top of the second spring 12 is connected to the inner wall of the top of the rear cover 2, and the bottom of the second spring 12 is connected to the outer wall of the top of the retaining ring 13. After the insertion tube 803 is inserted into the insertion sleeve 801, the assembly of the front cover 3 and the rear cover 2 is completed. Under the action of the second spring 12, the retaining ring 13 moves down along the insertion tube 803. The retaining rings 13 around the perimeter press against the outer walls of the four corners of the circuit board 5, so that the circuit board 5, the reflective liquid bladder plate 6 and the LED display screen 4 are tightly fitted, ensuring that the LED full-color display enhancement device is tightly assembled.

[0047] Furthermore, a rubber pad is attached to the bottom outer wall of the retaining ring 13. The rubber pad at the bottom of the retaining ring 13 is designed to prevent the retaining ring 13 from damaging the circuit board 5.

[0048] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7The sealed water-cooled heat dissipation assembly 9 includes a stepped groove 901 formed on the top outer wall of the front cover 3, a liquid bladder sealing ring 902 fitted on the outer wall of the stepped groove 901, a liquid tank 903 fixed on one side outer wall of the rear cover 2, a liquid pump 904 installed on one side outer wall of the rear cover 2, the suction end of the liquid pump 904 connected to the inside of the liquid tank 903, the pumping end of the liquid pump 904 connected to a pumping pipe 905, one end of the pumping pipe 905 connected to the inside of the liquid bladder sealing ring 902, a return pipe 906 connected through one side outer wall of the liquid bladder sealing ring 902, and a constant pressure relief valve 907 installed at the end of the return pipe 906. Furthermore, the other end of the return pipe 906 is connected to the inside of the liquid tank 903. A radiator 908 is installed through the outer wall of the middle part of the return pipe 906, and the radiator 908 is fixed to the outer wall of the rear cover 2. A liquid injection pipe 909 is connected through the inner wall of one side of the liquid bladder sealing ring 902, and one end of the liquid injection pipe 909 is connected to the inside of the reflective liquid bladder plate 6. A micro-controlled electromagnetic pressure relief valve 910 is installed through the end of the liquid injection pipe 909. During the assembly of the front cover 3 and the rear cover 2, the liquid bladder sealing ring 902 is fitted on the stepped groove 901 of the front cover 3, so that the liquid bladder sealing ring 902 is positioned between the front cover 3 and the rear cover 2. During the operation of the full-color display enhancement device, the control pump 904 pumps coolant from the tank 903, which is then introduced into the liquid bladder sealing ring 902 through the pump pipe 905. The liquid bladder sealing ring 902 expands after being filled with liquid, ensuring the sealing of the LED display housing, preventing dust and moisture intrusion, improving the lifespan of the LED display, and solving the problem of light leakage affecting display quality in traditional LED displays. When the hydraulic pressure in the liquid bladder sealing ring 902 reaches the threshold of the micro-controlled electromagnetic pressure relief valve 910, coolant is introduced into the reflective liquid bladder plate 6. The threshold of the micro-controlled electromagnetic pressure relief valve 910 is adjusted accordingly. The reflective liquid bladder plate 6 can adjust the curvature of its inner concave wall, thereby adjusting the reflectivity. During operation, the coolant in the reflective liquid bladder plate 6 and the liquid bladder sealing ring 902 absorbs the heat generated by the LED display. When the pressure in the liquid bladder sealing ring 902 reaches the threshold of the constant pressure relief valve 907, the coolant that has absorbed heat is discharged through the return pipe 906. The coolant exchanges heat with the outside air through the radiator 908, dissipating the heat absorbed by the coolant. The cooled coolant then flows back to the liquid tank 903 through the return pipe 906, realizing the circulating liquid cooling of the LED full-color display device.

[0049] Furthermore, the injection tube 909 is a telescopic flexible tube. U-shaped grooves 10 are provided on the inner wall of one side of the stepped groove 901 and the outer wall of one side of the circuit board 5, corresponding to the injection tube 909. During the assembly of the front cover 3 and the rear cover 2, the injection tube 909 passes through the U-shaped groove 10, which is conducive to the overall assembly and installation of the LED display.

[0050] Furthermore, the interior of the liquid tank 903 is filled with coolant, and a liquid injection port is installed through the top side outer wall of the liquid tank 903 to replenish the coolant inside the liquid tank 903.

[0051] In this embodiment, refer to Figure 1 , Figure 2 , Figure 6 and Figure 8 A control chip 51 is installed on the outer wall of the middle part of the circuit board 5. A power module 52, an LED full-color display module 53, and an eye-tracking data acquisition module 54 are distributed and installed on one outer wall of the circuit board 5. An eye-tracking camera 55 is installed on the outer wall of the top of the liquid tank 903. A vision analysis and detection module 56, a vision data output module 57, and an adaptive display enhancement module 58 are distributed and installed on one outer wall of the circuit board 5. The eye-tracking data acquisition module 54, the vision analysis and detection module 56, the vision data output module 57, and the adaptive display enhancement module 58 are electrically connected. The eye-tracking camera... The eye-tracking camera 55 is electrically connected to the eye-tracking data acquisition module 54, and the adaptive display enhancement module 58 is electrically connected to the LED full-color display module 53. The output terminal of the LED full-color display module 53 is electrically connected to the input terminal of the LED display screen 4. A reflective surface adjustment module 59 is installed on one outer wall of the circuit board 5. The electrical output terminal of the reflective surface adjustment module 59 is electrically connected to the electrical input terminal of the micro-controlled electromagnetic pressure relief valve 910. During the use of this LED full-color display enhancement device, while the user is viewing the LED display screen 4, the eye-tracking camera 55 works synchronously to track the user's eyes. The system performs eye-tracking monitoring to acquire and monitor the user's pupil data. The eye-tracking data acquisition module 54 collects the acquired pupil data, and the vision analysis and detection module 56 analyzes the acquired pupil data to identify the user's vision problems (normal, myopia, astigmatism, and presbyopia). The vision data output module 57 inputs the user's vision problems into the adaptive display enhancement module 58. The adaptive display enhancement module 58, based on the corresponding vision problem, adaptively optimizes and enhances the LED display parameters according to an algorithm. The optimized and enhanced LED display data is then displayed through the LED full-color display module 53. The output is displayed on LED display screen 4. In summary, this LED full-color display enhancement device uses eye-tracking camera 55 to perform visual detection on the user, analyze the user's vision, and automatically optimize LED display parameters according to the user's vision to achieve adaptive enhancement of LED full-color display. The threshold of the micro-controlled electromagnetic pressure relief valve 910 can be adjusted, and the curvature of the concave wall of the reflective liquid bladder plate 6 can be adjusted by adjusting the threshold of the micro-controlled electromagnetic pressure relief valve 910, thereby adjusting the reflectivity of the LED display and facilitating the adjustment of LED full-color display enhancement.

[0052] Furthermore, the adaptive display enhancement module 58 internally includes a dynamic contrast adjustment unit, an intelligent sharpening and edge enhancement unit, a color perception compensation algorithm unit, and a brightness / gamma value optimization unit. The vision data output module 57 internally includes a vision data input interface. The dynamic contrast adjustment unit adjusts the dynamic contrast of the display, the intelligent sharpening and edge enhancement unit adjusts the sharpness of the display, the color perception compensation algorithm unit adjusts the color direction texture of the display, and the brightness / gamma value optimization unit adjusts the brightness / gamma value of the display. In the algorithm of the adaptive display enhancement module 58, when the vision is myopia, the sharpness is enhanced (1.5-3 times edge enhancement) for optimization adjustment; when the vision is astigmatic, the specific direction texture is enhanced for optimization adjustment; and when the vision is presbyopia, the UI elements are enlarged by 15-30% for optimization adjustment. This achieves automatic optimization of LED display parameters according to the user's vision condition. The vision data input interface allows the user to manually input vision data.

[0053] Furthermore, a gimbal 14 is installed on the bottom outer wall of the eye-tracking camera 55, and a heat-absorbing pipe 16 is wound and connected to the outer wall of the eye-tracking camera 55. A three-way connector 15 is installed through the outer wall of the end of the return pipe 906. One end of the heat-absorbing pipe 16 is connected to one end of the three-way connector 15, and one end of the heat-absorbing pipe 16 passes through the interior of the liquid tank 903. The setting of the gimbal 14 makes the monitoring and shooting of the eye-tracking camera 55 more stable. During the return flow of the coolant in the return pipe 906, the coolant flows back into the liquid tank 903 through the three-way connector 15 and the heat-absorbing pipe 16. The heat-absorbing pipe 16, wound around the outside of the eye-tracking camera 55, plays a role in heat dissipation during the flow of coolant, which is conducive to the stable operation of the eye-tracking camera 55.

[0054] Working Principle: In use, during the assembly of the LED full-color display enhancement device, the reflective liquid bladder plate 6 and the mounting holes 802 on the circuit board 5 are aligned and fitted onto the outer wall of the insertion sleeve 801 inside the front cover 3. Then, the rear cover 2 is closed on top of the front cover 3, so that the insertion tube 803 on the inner wall of the rear cover 2 is aligned and inserted into the insertion sleeve 801. During this process, the handle 808 is rotated so that the locking block 807 at the end of the connecting rod 804 is aligned with the slot 809 on the insertion sleeve 801. Then, pressing the handle 808 causes the locking block 807 to move downward through the connecting rod 804, so that the locking block 807 is inserted into the bottom of the slot 809. During the downward movement of the connecting rod 804, the limiting plate 805 moves downward within the insertion tube 803 and compresses the first spring. Spring 806, through handle 808, drives connecting rod 804 and locking block 807 to rotate. Locking block 807 rotates along arc groove 810 to below locking groove 811. Then, handle 808 is released. Under the action of the first spring 806, limiting plate 805 and connecting rod 804 move upward, thereby driving locking block 807 to move upward and engage in locking groove 811, realizing the locking and fixing of insert tube 803 into insert sleeve 801. Under the action of the second spring 12, pressing ring 13 moves downward along insert tube 803. The pressing ring 13 around the four corners of the circuit board 5 presses against the outer wall, making circuit board 5, reflective liquid bladder plate 6 and LED display screen 4 tightly fit together, ensuring tight assembly of LED full-color display enhancement device, realizing LED display The assembly of the device allows for easy disassembly of the LED display structure, facilitating maintenance and repair of the LED full-color display enhancement device. During the assembly of the front cover 3 and the rear cover 2, a liquid bladder sealing ring 902 is fitted onto the stepped groove 901 of the front cover 3, positioning the liquid bladder sealing ring 902 between the front cover 3 and the rear cover 2. During the use of the LED full-color display enhancement device, the control pump 904 pumps the coolant from the liquid tank 903, which is then pumped into the liquid bladder sealing ring 902 through the pump pipe 905. The liquid bladder sealing ring 902 expands after being filled with liquid, ensuring the sealing of the LED display assembly shell, preventing dust and moisture intrusion, improving the lifespan of the LED display, and solving the problem of light leakage affecting display quality in traditional LED displays. The problem is that when the hydraulic pressure inside the liquid bladder seal ring 902 reaches the threshold of the micro-controlled electromagnetic pressure relief valve 910, coolant is input into the reflective liquid bladder plate 6. The reflective coating 7 on the inner concave wall of the reflective liquid bladder plate 6 reflects the light displayed on the LED display screen 4, enhancing the full-color LED display effect. By adjusting the threshold of the micro-controlled electromagnetic pressure relief valve 910, the curvature of the inner concave wall of the reflective liquid bladder plate 6 can be adjusted, thereby adjusting the reflectivity and facilitating the enhancement of the full-color LED display. During operation, the coolant in the reflective liquid bladder plate 6 and the liquid bladder seal ring 902 absorbs the heat generated by the LED display. When the hydraulic pressure inside the liquid bladder seal ring 902 reaches the threshold of the constant pressure relief valve 907, the cooled coolant, after absorbing heat, is discharged through the return pipe 906.The coolant exchanges heat with the outside air through the radiator 908, dissipating the heat absorbed by the coolant. The cooled coolant then flows back to the liquid tank 903 through the return pipe 906, achieving circulating liquid cooling for the LED full-color display device. While the user is viewing the LED display screen 4, the eye-tracking camera 55 simultaneously monitors the user's eyes, acquiring pupil data. The eye-tracking data acquisition module 54 collects the acquired pupil data, and the vision analysis and detection module 56 analyzes the acquired pupil data to identify the user's vision problems (normal, myopia, astigmatism, and presbyopia). The vision data output module 57 inputs the user's vision problems into the adaptive display enhancement module 58. Block 58, corresponding to vision problems, adaptively optimizes and enhances the LED display parameters according to the algorithm. The optimized and enhanced LED display data is output through the LED full-color display module 53 and displayed on the LED display screen 4. In summary, this LED full-color display enhancement device uses an eye-tracking camera 55 to perform visual detection on the user, analyze the user's vision status, and automatically optimize the LED display parameters based on the user's vision status, achieving adaptive enhancement of the LED full-color display. The threshold of the micro-controlled electromagnetic pressure relief valve 910 can be adjusted, and by adjusting the threshold of the micro-controlled electromagnetic pressure relief valve 910, the curvature of the concave wall of the reflective liquid bladder plate 6 can be adjusted, thereby adjusting the LED display reflectivity and facilitating the adjustment of LED full-color display enhancement.
