By controlling the amount of liquid injected into the reflective liquid sac plate, the curvature of the concave inner wall can be adjusted, thereby realizing the adjustment of the reflectivity, which is beneficial to the enhancement adjustment of the LED full-color display. The setting of the reflective liquid sac plate structure between the LED display screen and the circuit board also plays a role in shock absorption and heat absorption between the LED display screen and the circuit board; For this LED full-color display enhancement device, during the process of the user watching the LED display screen, the eye movement tracking camera conducts eye movement tracking and monitoring on the user's eyes, monitors and obtains pupil data, analyzes the pupil data, identifies the user's vision problems, and adaptively optimizes and enhances the LED display parameters according to the algorithm corresponding to the vision problems, realizing the adaptive enhancement of the LED full-color display; Through the setting of the snap-fit assembly component, the snap-fit assembly of the LED display housing can be realized.

[0035] Working principle: When the present invention is in use, during the assembly process of the LED full-color display enhancement device on the LED display, the reflective liquid sac plate 6 and the sleeve holes 802 on the circuit board 5 are aligned and sleeved on the outer wall of the socket sleeve 801 inserted into the front cover 3. Then, the rear cover 2 is covered on the top of the front cover 3, so that the socket tube 803 on the inner wall of the rear cover 2 is inserted into the socket sleeve 801. During this process, the handle 808 is rotated to align the block 807 at the end of the connecting rod 804 with the slot 809 on the socket sleeve 801. Then, the handle 808 is pressed to drive the block 807 to move downward through the connecting rod 804, so that the 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 be driven to move downward in the socket tube 803 and compress the first spring 806. Then, the handle 808 is used to drive the connecting rod 804 and the block 807 to rotate. The block 807 rotates along the arc groove 810 to below the card slot 811. Then, the handle 808 is released. Under the action of the first spring 806, the limiting plate 805 and the connecting rod 804 are driven to move upward, thereby driving the block 807 to move upward and engage with the card slot 811, realizing the snap-fitting fixation of the socket tube 803 inserted into the socket sleeve 801. Under the action of the second spring 12, the pressing ring 13 is driven to move downward along the socket tube 803, and the surrounding pressing rings 13 press the outer walls of the four corners of the circuit board 5, so that the circuit board 5, the reflective liquid sac plate 6 and the LED display screen 4 are closely attached, ensuring the tight assembly of the LED full-color display enhancement device and realizing the assembly of the LED display. In the later stage, the structure of the LED display can be conveniently disassembled, which is beneficial to the maintenance and repair of the LED full-color display enhancement device. During the assembly process of the front cover 3 and the rear cover 2, the liquid sac sealing ring 902 is sleeved on the step groove 901 of the front cover 3, so that the liquid sac sealing ring 902 is arranged between the front cover 3 and the rear cover 2. During the use of the LED full-color display enhancement device, the liquid pump 904 is controlled to work to pump and suck the coolant in the liquid tank 903 and input it into the liquid sac sealing ring 902 through the liquid pumping pipe 905. The liquid sac sealing ring 902 is inflated by injecting liquid to ensure the sealing of the assembly shell of the LED display, avoid the intrusion of dust and water vapor, improve the service life of the LED display, and also solve the problem that the traditional LED display has light leakage and affects the display quality. When the hydraulic pressure in the liquid sac sealing ring 902 reaches the threshold value of the micro-controlled electromagnetic pressure relief valve 910, the coolant is input into the reflective liquid sac plate 6. The reflective coating 7 on the concave wall of the reflective liquid sac plate 6 can reflect the display light of the LED display screen 4, enhancing the LED full-color display effect. By adjusting the threshold value of the micro-controlled electromagnetic pressure relief valve 910, the curvature of the concave wall of the reflective liquid sac plate 6 can be adjusted, thereby realizing the adjustment of the reflectivity, which is beneficial to the LED full-color display enhancement adjustment. During the working process, the coolant in the reflective liquid sac plate 6 and the liquid sac sealing ring 902 absorbs the heat generated by the operation of the LED display. When the continuous liquid pumping makes the hydraulic pressure in the liquid sac sealing ring 902 reach the threshold value of the constant pressure relief valve 907, the heat-absorbed coolant is discharged through the liquid return pipe 906.The coolant exchanges heat with the external air through the radiator 908, discharges the heat absorbed by the coolant, and the cooled coolant flows back into the liquid tank 903 through the return pipe 906 to achieve the circulating liquid cooling of the LED full-color display device; during the process of the user watching the LED display screen 4, the eye movement tracking camera 55 works synchronously to conduct eye movement tracking and monitoring on the user's eyes, monitor and obtain the pupil data of the user, the eye movement data acquisition module 54 collects the obtained pupil data, the vision analysis and detection module 56 analyzes the collected pupil data, analyzes and identifies the user's vision problems (normal, myopia, astigmatism, and presbyopia), and 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 adaptively optimizes and enhances the LED display parameters according to the algorithm corresponding to the vision problems, and the optimized and enhanced LED display data is output through the LED full-color display module 53 and displayed at the LED display screen 4. In summary, the LED full-color display enhancement device conducts visual detection on the user through the eye movement tracking camera 55, analyzes the user's vision condition, and automatically optimizes the LED display parameters according to the user's vision condition to achieve the adaptive enhancement of the LED full-color display; the threshold value of the micro-controlled electromagnetic pressure relief valve 910 can be adjusted through the micro-controlled electromagnetic pressure relief valve 910, and by adjusting the threshold value of the micro-controlled electromagnetic pressure relief valve 910, the curvature of the concave wall of the reflection liquid capsule plate 6 can be adjusted, realizing the adjustment of the LED display reflectivity, which is beneficial to the adjustment of the LED full-color display enhancement.
