[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Embodiment 1: The present invention provides a high-frequency refresh liquid crystal display, such as Figures 1 to 7 As shown, it includes a polarizing plate 1, a glass substrate 2 is fixedly connected to the bottom of the polarizing plate 1, a color filter film 3 is fixedly connected to the bottom of the glass substrate 2, an orientation layer 4 is fixedly connected to the bottom of the color filter film 3, a glass substrate 2 5 is fixedly connected to the bottom of the orientation layer 4, a polarizing plate 2 6 is fixedly installed at the bottom of the glass substrate 2 5, a transistor 8 is surrounded inside the glass substrate 2 5, an orientation film 9 is fixedly connected to the middle of the transistor 8, an X-shaped electrode 7 is fixedly installed on the X-axis of the transistor 8, and a Y-axis of the transistor 8 is fixedly installed There is a Y-shaped electrode 13, and a plastic frame 10 is installed on the outer side of the glass substrate 2 and the polarizing plate 1. A through hole is opened at the top of the plastic frame 10 corresponding to the middle area of ​​the glass substrate 2 and the polarizing plate 1 for the flow of light sources. A clamping and positioning component 11 is symmetrically installed inside the plastic frame 10, and the polarizing plate 1, the glass substrate 2, the color filter film 3, the orientation layer 4, the glass substrate 5, the polarizing plate 6, the X-shaped electrode 7, the transistor 8, the orientation film 9 and the Y-shaped electrode 13 are assembled in sequence to form a liquid crystal display screen;

[0030] The clamping positioning assembly 11 includes a rotatably connected positioning shaft 1101, with connecting pieces 1102 integrally formed on both sides of the outer surface of the positioning shaft 1101, a rotating plate 1114 rotatably connected to the middle of the outer surface of the positioning shaft 1101, a cylinder 1106 symmetrically fitted at the bottom end of the connecting piece 1102, and a pushing plate 1107 fixedly installed at one end of the cylinder 1106.

[0031] like Figure 4 and Figure 5 As shown, a torsion spring 1103 is installed between the inner wall of the connecting member 1102 and the outer side of the positioning shaft 1101, and one end of the torsion spring 1103 is fixedly installed inside the rubber frame 10. The overall shape of the connecting member 1102 is concave;

[0032] When the connecting member 1102 is squeezed, it rotates, and the positioning shaft 1101 is driven to rotate when the connecting member 1102 rotates. When the positioning shaft 1101 and the connecting member 1102 rotate synchronously, the torsion spring 1103 is twisted, and the connecting member 1102 is reset under the reaction force of the torsion spring 1103, thereby changing the difficulty of resetting the connecting member 1102.

[0033] like Figure 6 and Figure 7 As shown, the outer surface of the positioning shaft 1101 is symmetrically connected with a one-way bearing 1104 through interference fit, the rotating plate 1114 is slidably connected to the outside of the one-way bearing 1104, a convex block is welded on the outer ring of the one-way bearing 1104, and a sliding groove is provided at one end of the rotating plate 1114 corresponding to the convex block. The number of the one-way bearings 1104 is set to two, and the rotation directions of the two one-way bearings 1104 are opposite;

[0034] During the rotation of the two one-way bearings 1104 in opposite directions, the rotating plate 1114 forms a whole through the two one-way bearings 1104 and the positioning shaft 1101, so that the rotating plate 1114 rotates with the rotation of the positioning shaft 1101. When the rotating plate 1114 is moved, the rotating plate 1114 moves on the outside of the protrusion through the slide groove, which causes the rotating plate 1114 and one of the one-way bearings 1104 to separate, so that the rotating plate 1114 and the positioning shaft 1101 can rotate independently, thereby achieving the purpose of changing the angle of the rotating plate 1114 when the positioning shaft 1101 is stationary.

[0035] like Figure 6 and Figure 7 As shown, the outer side of the one-way bearing 1104 is fitted with an abutment 1110, and a spring rod 1111 is symmetrically embedded and installed at the bottom of one end of the abutment 1110, and an L-shaped plate 1112 is clamped and installed at one end of the two spring rods 1111, and a spring rod 2 1113 is symmetrically clamped and installed at one end of the L-shaped plate 1112, and the fixed end of the spring rod 2 1113 is embedded and installed inside the rubber frame 10;

[0036] By pushing the L-shaped plate 1112, the L-shaped plate 1112 moves, which drives the spring rod 1111 to move. The spring rod 1111 moves, which drives the abutment 1110 to enter the outside of the one-way bearing 1104, thereby limiting the rotating plate 1114 sleeved on the outside of the one-way bearing 1104, preventing the rotating plate 1114 from being displaced left and right after installation.

[0037] like Figure 4 and Figure 5 As shown, a flip V-shaped plate 1109 is rotatably connected inside the rubber frame 10, the bottom end surface of the flip V-shaped plate 1109 and the edge of the polarizing plate 11 fit together, and the top end surface of the flip V-shaped plate 1109 and the inner wall of the L-shaped plate 1112 fit together;

[0038] When the flip V-shaped plate 1109 is squeezed by the polarizing plate 1, the polarizing plate 1 is subjected to force and rotates. When the polarizing plate 1 rotates, the L-shaped plate 1112 is driven to move, thereby changing the difficulty of moving the L-shaped plate 1112.

[0039] like Figure 4 and Figure 5 As shown, the positioning bar 1105 is symmetrically and movably connected at the two ends of the abutment member 1110 on the outside of the positioning shaft 1101, and the push plate 1107 is slidably connected to the bottom end of the positioning bar 1105 and the push plate 1107 is slidably connected to the inside of the rubber frame 10;

[0040] The positioning bar 1105 limits the movement of the push plate 1107, so that the push plate 1107 can only move forward and backward but cannot deflect.

[0041] like Figure 5 and Figure 6 As shown, a rounded plate 1108 is fixedly installed in the middle of one end of the push plate 1107, and one end surface of the rounded plate 1108 and the top of the flip V-shaped plate 1109 are in contact with each other;

[0042] When the flip V-shaped plate 1109 is flipped, it can drive the rounded corner plate 1108 to move, thereby changing the difficulty of moving the rounded corner plate 1108.

[0043] like Figure 1 As shown, a placement frame 12 is mounted between the polarizing plate 1, the glass substrate 2, the color filter film 3, the alignment layer 4, the glass substrate 5, the polarizing plate 6 and the outer side of the plastic frame 10;

[0044] It is used for assembling the polarizing plate 1, the glass substrate 2, the color filter film 3, the orientation layer 4, the glass substrate 2 5, the polarizing plate 2 6 and the rubber frame 10, and limiting the outer sides of the polarizing plate 1, the glass substrate 2, the color filter film 3, the orientation layer 4, the glass substrate 2 5 and the polarizing plate 2 6, so that the installation positions of the polarizing plate 1, the glass substrate 2, the color filter film 3, the orientation layer 4, the glass substrate 2 5 and the polarizing plate 2 6 are more accurate.

[0045] like Figure 2 and Figure 3 As shown, the polarizing plate 1 and the glass substrate 2 are integrally formed with positioning blocks at both ends, and the two ends of the plastic frame 10 are provided with fitting grooves, and the positioning blocks are located inside the fitting grooves of the plastic frame 10;

[0046] Through the action of the fitting groove, the positioning blocks of the polarizing plate 1 and the glass substrate 2 are installed inside the glue frame 10, so that the polarizing plate 1 and the glass substrate 2 are fixed to the glue frame 10, and the positioning and fixing difficulty is changed, so that the glue bonding between the polarizing plate 1 and the glass substrate 2 is blocked.

[0047] Working principle: During the actual use of the device, the glass substrate 2 is connected to the plastic frame 10. At this time, the glass substrate 2 first contacts the connecting piece 1102. When the connecting piece 1102 is squeezed, it rotates. When the connecting piece 1102 rotates, it drives the positioning shaft 1101 to rotate. When the positioning shaft 1101 and the connecting piece 1102 rotate synchronously, the torsion spring 1103 is twisted. At this time, the glass substrate 2 still moves downward, and at this time, after the connecting piece 1102 is turned over 90 degrees, the rotating plate 1114 is horizontal with the ground, and at the same time, the glass substrate 2 continues to move downward. At this time, the glass substrate 2 and the flip V-shaped plate 1 109 contacts and drives the flip V-shaped plate 1109 to flip, and when the flip V-shaped plate 1109 rotates, it drives the rounded plate 1108 to move, and when the rounded plate 1108 moves, it drives the push plate 1107 to move, and when the push plate 1107 moves, it enters the outside of the glass substrate 12, and at the same time drives the L-shaped plate 1112 to move under the force again, and when the L-shaped plate 1112 moves, it drives the spring rod 1113 to stretch, and in this process, the abutment 1110 is driven by the spring rod 1111 to enter the outside of the two one-way bearings 1104, and then when the glass substrate 12 is separated from the flip V-shaped plate 1109 and enters the inside of the rubber frame 10;

[0048] Then push the glass substrate 12, at this time, the torsion spring 1103 and the spring rod 1113 drive the positioning shaft 1101 and the flip V-shaped plate 1109 to reset, at this time, the flip V-shaped plate 1109 and the positioning shaft 1101 The driven structural parts are reset, and then the polarizing plate 1 is installed. When the polarizing plate 1 is installed, due to the above operation, the connecting member 1102 is located on the vertical surface of the polarizing plate 1, and the rotating plate 1114 is attached to the horizontal surface of the polarizing plate 1, and the driving plate 1107 is driven to enter the outside of the polarizing plate 1 and the glass substrate 2 during the synchronization process. By adjusting the polarizing plate 1 and the glass substrate 2, the polarizing plate 1 and the glass substrate 2 are rotated. The relative squeezing between the glass substrates 2 and the vertical squeezing between the polarizing plate 1, the glass substrate 2 and the plastic frame 10 can effectively remove the small air gap between the polarizing plate 1 and the glass substrate 2, thereby reducing the scattered light loss that may be caused by the gap, improving the overall brightness of the screen, and ensuring the close contact between the polarizing plate 1 and the surface of the glass substrate 2, which can reduce the uneven intensity of light from different areas, thereby improving the uniformity and contrast of the display screen, making the display effect more delicate and natural, and at the same time helping to form a more uniform pressure distribution around the frame, reducing potential damage caused by stress concentration;

[0049] Then, when the personnel need to disassemble the polarizing plate 1 and the glass substrate 2, the personnel push the abutment member 1110. When the abutment member 1110 moves, it is blocked by the L-shaped plate 1112, which causes the spring rod 1111 to be compressed, and the abutment member 1110 to move. Then, the rotating plate 1114 is moved, and the rotating plate 1114 is separated along one of the one-way bearings 1104, and the other one-way bearing 1104 is separated from the rotating plate 1114. Then, the rotating plate 1114 is rotated upward so that the rotating plate 1114 is perpendicular to the ground. Then, the glass substrate 2 is pushed from the bottom end of the plastic frame 10, and the glass substrate 2 drives the separation between the polarizing plate 1 and the plastic frame 10, which facilitates the disassembly between the glass substrate 2, the polarizing plate 1 and the plastic frame 10, and changes the disassembly difficulty between the glass substrate 2, the polarizing plate 1 and the plastic frame 10, thereby improving the disassembly efficiency of the glass substrate 2, the polarizing plate 1 and the plastic frame 10.

[0050] Finally, the X-type electrode 7, transistor 8, Y-type electrode 13, orientation film 9 and glass substrate 2 5 are connected. At this time, the glass substrate 2 5 is connected to the polarizing plate 2 6, and then the orientation layer 4, color filter film 3, glass substrate 1 2 and polarizing plate 1 are fixed on the glass substrate 2 5 in sequence to form a high-frequency refresh liquid crystal display screen, and then they are put together and placed inside the frame 12 to form a display. At this time, the arrangement of liquid crystal molecules is controlled by changing the driving signals of the X-type electrode 7, transistor 8 and Y-type electrode 13, thereby changing the passage and refraction of light to realize image display. The image can change quickly through fast-response electrical control, thereby achieving a high refresh rate, and thus the manufactured display screen has the purpose of high-frequency refresh.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
