DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 9 The present invention provides an LED display module, comprising an upper polarizer 101 in a U-shaped structure, a thin film transistor liquid crystal display 102, a lower polarizer 103, a backlight module 104, and a lower iron frame 105;

[0037] It also includes a self-rotating part, a connecting part and a pressing part. The self-rotating parts are evenly distributed on the upper polarizer 101, the thin film transistor liquid crystal display 102, the lower polarizer 103, the backlight module 104 and the lower iron frame 105. The self-rotating part also transmits a pull rope 2. The middle part of the backlight module 104 is rotatably connected to a control disk 3 wound with the pull rope 2. By rotating the control disk 3, the self-rotating part rotates, so that the upper polarizer 101, the thin film transistor liquid crystal display 102, the lower polarizer 103 and the backlight module 104 move, and the pressing part moves them in sequence for packaging;

[0038] The rotating disk 4 and the control disk 3 are connected to make the rotating disk 4 rotate in a gap, so that the lower iron frame 105 moves in a gap with the rotating part.

[0039] The rotating part includes a plug board 5 which is plugged and fixed to the upper polarizer 101; the end of the thin film transistor liquid crystal display 102 is rotatably connected to the first rotation rod 6 and the second rotation rod 7 which are distributed in upper and lower positions; the end of the lower polarizer 103 is rotatably connected to the third rotation rod 8 and the fourth rotation rod 9 which are distributed in upper and lower positions; the end of the backlight module 104 is rotatably connected to the fifth rotation rod 10; one end of the pull rope 2 is hung on the plug board 5, and is sequentially connected to the first rotation rod 6, the second rotation rod 7, the third rotation rod 8, the fourth rotation rod 9 and the fifth rotation rod 10 for transmission; the other end of the pull rope 2 is wound and connected to the control panel 3.

[0040] When it is necessary to disassemble, the control plate 3 is reversed, and the pull rope 2 is pulled. The pull rope 2 uses the first rotating rod 6 as a fulcrum to move the plug board 5 upward, so that even if the upper polarizer 101 moves away from the thin film transistor liquid crystal display 102, the thin film transistor liquid crystal display 102 does not move. After the upper polarizer 101 moves a fixed distance, the rotating plate 4 rotates a certain angle and then stops rotating, so that the lower iron frame 105 is away from the backlight module 104 by a certain distance;

[0041] The control plate 3 is continuously reversed. Under the action of the pressing member, the upper polarizer 101 that continues to move drives the thin film transistor liquid crystal display 102 to move. The first self-rotating rod 6 and the second self-rotating rod 7 move upward synchronously. At this time, the pull rope 2 uses the third self-rotating rod 8 as a fulcrum. The upper polarizer 101 and the thin film transistor liquid crystal display 102 move away from the lower polarizer 103 synchronously. The lower polarizer 103 does not move. After the upper polarizer 101 and the thin film transistor liquid crystal display 102 move a fixed distance, the rotating plate 4 rotates a certain angle and then stops rotating, so that the lower iron frame 105 is further away from the backlight module 104 by a certain distance.

[0042] Continue to reverse the control disk 3. Under the action of the pressing member, the upper polarizer 101 and the thin film transistor liquid crystal display 102 that continue to move drive the lower polarizer 103 to move. The first self-rotating rod 6, the second self-rotating rod 7, the third self-rotating rod 8 and the fourth self-rotating rod 9 move upward synchronously. At this time, the pull rope 2 uses the fifth self-rotating rod 10 as a fulcrum, and the upper polarizer 101, the thin film transistor liquid crystal display 102 and the lower polarizer 103 move away from the backlight module 104 synchronously. The backlight module 104 remains stationary, and the upper polarizer 101, the thin film transistor liquid crystal display 102 and the lower polarizer 103 move a fixed distance. At the same time, the rotating disk 4 rotates again at a certain angle and then stops rotating, so that the lower iron frame 105 is further away from the backlight module 104 by a certain distance.

[0043] At this time, the upper polarizer 101, the thin film transistor liquid crystal display 102, the lower polarizer 103, the backlight module 104, and the lower iron frame 105 are separated from each other, and the spacing is consistent, which is convenient for replacement. For example, if there is a problem with the packaged thin film transistor liquid crystal display 102, the entire LED display screen can be disassembled, the thin film transistor liquid crystal display 102 can be replaced, and then the pull rope 2 is re-connected to the first rotation rod 6 and the second rotation rod 7 on the thin film transistor liquid crystal display 102, and finally the control disk 3 is rotated to make the upper polarizer 101, the thin film transistor liquid crystal display 102, the lower polarizer 103, the backlight module 104, and the lower iron frame 105 close to each other and fit together, thereby completing the repackaging. This method is simple and convenient to operate, has strong applicability, and makes maintenance and replacement more convenient.

[0044] The pressing member includes a plurality of pressing blocks 11 and matching blocks 12. The plurality of pressing blocks 11 are respectively fixedly connected to one side of the upper polarizer 101, the thin film transistor liquid crystal display 102 and the lower polarizer 103. The plurality of matching blocks 12 are respectively fixedly connected to the other side of the thin film transistor liquid crystal display 102, the lower polarizer 103 and the backlight module 104.

[0045] The pressing block 11 is in an L-shaped structure, and the plurality of pressing blocks 11 are respectively slidably limited with the thin film transistor liquid crystal display 102, the lower polarizer 103 and the backlight module 104, thereby limiting each other to avoid misalignment between the upper polarizer 101, the thin film transistor liquid crystal display 102, the lower polarizer 103 and the backlight module 104;

[0046] When it is necessary to disassemble and replace, the upper polarizer 101 is moved upward under the action of the pull rope 2, thereby driving the pressing block 11 on the upper polarizer 101 to move. The upper polarizer 101 moves upward by a fixed distance, and the pressing block 11 on the upper polarizer 101 moves synchronously by an equal fixed distance. At this time, the pressing block 11 on the upper polarizer 101 contacts the matching block 12 on the thin film transistor liquid crystal display 102, so that the upper polarizer 101 drives the thin film transistor liquid crystal display 102 to move synchronously;

[0047] By analogy, after the pressing block 11 on the TFT-LCD display 102 moves a fixed distance, it contacts the matching block 12 on the lower polarizer 103, so that the TFT-LCD display 102 drives the lower polarizer 103 to move synchronously.

[0048] A fixed plate 13 is fixedly connected to the middle of the backlight module 104, the control disk 3 and the rotating disk 4 are both rotatably connected to the fixed plate 13, an adjusting handle 14 is fixedly connected to the middle of the control disk 3, and an elastic plate 15 that frictionally cooperates with the adjusting handle 14 is fixedly connected to the fixed plate 13;

[0049] By rotating the control disk 3, on the one hand, the pull rope 2 is pulled to realize the lamination or splitting and replacement of the upper polarizer 101, the thin film transistor liquid crystal display 102, the lower polarizer 103, and the backlight module 104, and on the other hand, the lower iron frame 105 is driven to be synchronously lamination or split and replaced;

[0050] When packaging, the end of the fixing plate 13 is pressed against the lower iron frame 105 to increase the tightness of the packaging.

[0051] A plurality of convex plates 16 are fixedly connected to the edge of the rotating disk 4, and a groove 17 is provided on the control disk 3 to rotate with the convex plates 16. Two adjacent convex plates 16 press against the edge of the control disk 3, and the control disk 3 continuously rotates. The edge of the control disk 3 presses against the two plates, so that the rotating disk 4 maintains this position and does not rotate.

[0052] When the groove 17 on the rotating control disk 3 contacts the convex plate 16, the convex plate 16 is sunken into the groove 17, and the rotating control disk 3 rotates the rotating disk 4 through the cooperation of the convex plate 16 and the groove 17. The circumferential length of the rotating disk 4 is the arc length between two adjacent convex plates 16, and then the groove 17 moves away from the convex plate 16. At this time, the other two convex plates 16 are pressed and matched with the edges of the control disk 3, so that the rotating disk 4 after rotation maintains a stable and non-rotating state again, that is, during the process of one rotation of the control disk 3, the rotating disk 4 is quickly rotated by a certain angle, and then maintains a stable and non-rotating state, so that the rotating disk 4 rotates a certain angle at a certain interval, and cooperates with the upper polarizer 101, the thin film transistor liquid crystal display 102, the lower polarizer 103, and the backlight module 104 to move in sequence, so that the packaging and removal and replacement processes are stable, and the moving and splitting distances are synchronized.

[0053] A fixed column 18 is fixedly connected to the edge of the rotating disk 4, a sliding rod 19 movably penetrates the fixed column 18, a sliding plate 20 is rotatably connected to the end of the sliding rod 19, a sliding groove 21 slidably matched with the sliding plate 20 is opened on the fixed plate 13, and the bottom end of the sliding plate 20 is plugged and fixed to the lower iron frame 105 through a plug-in block.

[0054] The rotating disk 4 rotates in the gap, driving the fixed column 18 to make a circular motion in the gap, so that the inclination angle of the sliding rod 19 changes, driving the sliding plate 20 to move along the sliding groove 21, and the sliding rod 19 slides adaptively on the fixed column 18, so that the lower iron frame 105 moves away from or close to the backlight module 104, so as to facilitate packaging or disassembly and replacement.

[0055] An LED display screen comprises an outer frame and a display module according to the above, wherein the display module is embedded in the outer frame, a transparent protective layer covering the display module is provided on the outer frame, and the display module is embedded in the outer frame and protected by covering the transparent protective layer.

[0056] A method for packaging a display module and an LED display screen, according to the above-mentioned LED display screen, the specific method includes the following steps:

[0057] S1, sequentially stack the upper polarizer 101, the thin film transistor liquid crystal display 102, the lower polarizer 103, the backlight module 104, and the lower iron frame 105, and wind the pull rope 2 around the rotating part, and then plug the plug board 5 into and fix it at the bottom end of the upper polarizer 101;

[0058] S2, rotating the control plate 3, pulling the pull rope 2, so that the lower polarizer 103, the thin film transistor liquid crystal display 102 and the upper polarizer 101 move downward synchronously and gradually fit each other;

[0059] When the control disk 3 rotates, the rotating disk 4 is driven to rotate in a gap, so that the sliding plate 20 rotates and slides adaptively, so that the lower iron frame 105 is close to the backlight module 104, thereby completing the packaging of the LED display screen.

[0060] S3, when it is necessary to disassemble for replacement, the control plate 3 is rotated in the reverse direction, and the pull rope 2 is pulled to move the upper polarizer 101 upward and away from the thin film transistor liquid crystal display 102. When the upper polarizer 101 moves a fixed distance, under the action of the pressing block 11 and the matching block 12, the thin film transistor liquid crystal display 102 and the upper polarizer 101 move upward synchronously, and the thin film transistor liquid crystal display 102 moves away from the lower polarizer 103;

[0061] S4, continue to rotate the control disk 3 in the reverse direction, and when the upper polarizer 101 and the thin film transistor liquid crystal display 102 move a fixed distance, the lower polarizer 103 is driven to move under the action of the pressing member;

[0062] S5, continue to rotate the control disk 3 in the reverse direction, after the lower polarizer 103, the thin film transistor liquid crystal display 102 and the upper polarizer 101 move upwards for a fixed distance synchronously, the backlight module 104 is driven to move under the action of the pressing member;

[0063] S6. When the control disk 3 rotates, the rotating disk 4 is driven to rotate in the gap, so that the sliding plate 20 rotates and slides adaptively, so that the lower iron frame 105 moves away, thereby completing the splitting of the LED display screen.
