Description

Technical Field

[0001] The present application relates to the technical field of splicing screens, and in particular to a method and structure for reducing a splicing seam of a splicing screen. Background Art

[0002] The splicing screen is a large-screen display device composed of multiple display units. It is widely used in monitoring centers, command and dispatch rooms, conference rooms, exhibition halls and other scenes. It forms an ultra-large screen by splicing multiple LCD display units, light-emitting diode display units or plasma display units of the same size together in a certain row and column manner. The Chinese patent with the announcement number "CN219318151U" discloses a mobile splicing screen, which includes a base, the upper end of the base is connected to the middle part of the frame of the X-shaped structure, the frame is provided with a slide groove near the end, a slider is slidably matched in the slide groove, and one end of the slider is transmission-connected to the driving module installed on the side of the frame, and the other end is fixedly connected to the mounting plate installed on the other side of the frame, the mounting plates are distributed in a rectangular array, and the slider is moved to a position away from the center of the frame. At this time, the spacing between the mounting plates is the largest, which is more conducive to the installation of the splicing screen. After the splicing screens are all installed on the corresponding mounting plates, the driving module is synchronously actuated to make the slider synchronously move to the center position of the frame, and the splicing screen fixed on the mounting plate moves accordingly, and the horizontal and vertical spacings of adjacent splicing screens are synchronously reduced until reaching the set value, and the slider stops moving. At this time, the horizontal and vertical gaps on the splicing screen are small, and the picture quality is relatively good; In the current application scenarios, splicing screens, with their large-screen display characteristics, provide convenience for information display to a certain extent, and play an important role in various public places and commercial environments. However, although splicing screens have certain adjustment functions, their overall structure is relatively simple in design, and there are obvious limitations in dealing with complex usage scenarios. For example, in crowded places such as squares, shopping malls, subway bus stations, and hospitals, the flow of people will increase significantly during daily peak hours or special events. During these peak traffic hours, people are densely distributed and the space is crowded. When people are on the floors directly above the display screen (such as the second and third floors), the display screen will be blocked. ) or directly below, it is difficult to directly observe the information displayed on the splicing screen due to the limitation of viewing angle. In addition, in some special periods, such as train stations during the Spring Festival travel rush, the crowd is extremely crowded and even the basic standing space is very limited. In this case, it becomes extremely difficult for people in the corner to obtain the content on the splicing screen. In summary, the existing splicing screen cannot meet people's needs for convenient information acquisition in special scenarios and peak hours. In order to improve its applicability in complex environments, it is necessary to make targeted improvements to the design of the splicing screen to enhance the effectiveness and accessibility of information display in various scenarios. Summary of the invention

[0003] In order to achieve multi-angle display for easy viewing during the application of the prior art display screen, the present application provides a method and structure for reducing the splicing seam of a spliced ​​screen.

[0004] The present application provides a method for reducing the splicing seam of a spliced ​​screen, which adopts the following technical solution: comprising the following steps: Step 1: Prepare materials. According to the required size of the splicing screen, purchase standard LCD display units with a size range of 46 inches and 55 inches. The diagonal error control range is ±0.1 inches. The thickness of the standard OC LCD glass is between 1.5mm and 2.0mm. Step 2: Polarizer processing: Use a polarizer to accurately cut off the polarizers on the upper and lower sides of the liquid crystal glass. The cutting accuracy of the polarizer is controlled at ±0.05mm to ensure that the edges are neat after cutting, prepare for subsequent cutting, remove unnecessary parts, and avoid interference caused by subsequent cutting; Step 3: Manual tearing: tear off the remaining polarizers on the upper and lower sides of the long LCD screen glass one by one. Since the glass thickness is only 1.5mm, professionals use their experience and skills to slowly tear off the polarizers with uniform force to prevent the glass from breaking. The tearing time for each polarizer is 30 seconds to 60 seconds to ensure the stability and safety of the operation. Step 4: Cutting. Place the LCD screen glass one by one on the cutting machine for cutting. The cutting speed of the cutting machine is set at 5mm / s-10mm / s, and the cutting accuracy is controlled at ±0.1mm. During the cutting process, the operator carefully holds the glass to avoid leakage or the screen failing to light up. The size error of the cut glass is ±0.2mm. Step 5: Timely seal. After the long LCD screen glass is cut into the required size, seal it immediately. Use the sealant for LCD glass and apply it evenly on the edge of the cut glass. The thickness of the glue layer is 0.2mm-0.3mm. Make sure that the sealant completely covers the cut edge to prevent liquid crystal molecules from flowing out and causing leakage. Step 6: Test. Use the motherboard to power on the long LCD screen after cutting and sealing. Focus on the screen display effect to see if there are bright spots, display anomalies, color uniformity deviation, ghosting, or missing lines. Use test equipment and software to measure the screen's brightness, contrast, color saturation and other parameters to ensure that all parameters meet the use standards of the spliced ​​screen.

[0018] The present application embodiment discloses a method for reducing the splicing seam of a spliced ​​screen. Figure 1-8 As shown, the following steps are included: Step 1: Prepare materials. According to the required size of the splicing screen, purchase standard LCD display units with a size range of 46 inches and 55 inches. The diagonal error control range is ±0.1 inches. The thickness of the standard OC LCD glass is between 1.5mm and 2.0mm. Step 2: Polarizer processing: Use a polarizer to accurately cut off the polarizers on the upper and lower sides of the liquid crystal glass. The cutting accuracy of the polarizer is controlled at ±0.05mm to ensure that the edges are neat after cutting, prepare for subsequent cutting, remove unnecessary parts, and avoid interference caused by subsequent cutting; Step 3: Manual tearing: tear off the remaining polarizers on the upper and lower sides of the long LCD screen glass one by one. Since the glass thickness is only 1.5mm, professionals use their experience and skills to slowly tear off the polarizers with uniform force to prevent the glass from breaking. The tearing time for each polarizer is 30 seconds to 60 seconds to ensure the stability and safety of the operation. Step 4: Cutting. Place the LCD screen glass one by one on the cutting machine for cutting. The cutting speed of the cutting machine is set at 5mm / s-10mm / s, and the cutting accuracy is controlled at ±0.1mm. During the cutting process, the operator carefully holds the glass to avoid leakage or the screen failing to light up. The size error of the cut glass is ±0.2mm. Step 5: Timely seal. After the long LCD screen glass is cut into the required size, seal it immediately. Use the sealant for LCD glass and apply it evenly on the edge of the cut glass. The thickness of the glue layer is 0.2mm-0.3mm. Make sure that the sealant completely covers the cut edge to prevent liquid crystal molecules from flowing out and causing leakage. Step 6: Test. Use the motherboard to power on the long LCD screen after cutting and sealing. Focus on the screen display effect to see if there are bright spots, display anomalies, color uniformity deviation, ghosting, or missing lines. Use test equipment and software to measure the screen's brightness, contrast, color saturation and other parameters to ensure that all parameters meet the use standards of the spliced ​​screen.

[0019] Please refer to Figure 6-Figure 8The adjusting mechanism 7 includes a concave seat 71, which is fixedly connected to the front side of the mounting block 64. The concave seat 71 is rotatably connected to a rotating shaft 72 inside. The front side of the rotating shaft 72 is fixedly connected to an adjusting assembly 73. The front end of the adjusting assembly 73 is fixedly connected to the back side of the display screen 4. The top of the concave seat 71 is fixedly connected to a second motor 74. The output end of the second motor 74 passes through the concave seat 71 and is fixedly connected to the top of the rotating shaft 72. The adjusting assembly 73 includes a base frame 731 and an articulated frame 732. The base frame 731 is fixedly mounted on the base frame 731 and is fixedly connected to the front side of the rotating shaft 72.

One end of the articulated frame 732 is hinged to the base frame 731. The middle part of the articulated frame 732 is hinged to the output end of the electric push rod 733. When the angle of the display screen 4 needs to be adjusted, , since the concave seat 71 is fixedly connected to the front of the mounting block 64, the second motor 74 fixedly connected to the top is started, and its output end passes through the concave seat 71 and drives the rotating shaft 72 connected thereto to rotate, and the base frame 731 fixedly connected to the front of the rotating shaft 72 rotates accordingly, thereby realizing the preliminary horizontal angle adjustment of the display screen 4. The electric push rod 733 hinged at the upper end of the base frame 731, after starting, its output end extends or contracts. Because one end of the articulated frame 732 is hinged to the base frame 731, and the middle part is hinged to the output end of the electric push rod 733, and the articulated frame 732 is fixedly connected to the back of the display screen 4, the action of the output end of the electric push rod 733 can push the articulated frame 732 to rotate around the hinge point with the base frame 731 through the articulated structure, thereby driving the display screen 4 to rotate on the base frame 731, completing the adjustment of the longitudinal angle, thereby realizing flexible horizontal and longitudinal angle adjustment of the display screen 4 to meet the display needs in different scenes.

The side frame 51 is arranged in a ring shape with equal spacing and fixedly installed on the back of the mounting plate 2. The bevel gear ring 53 is rotatably connected to the inner side of the side frame 51. The driving assembly 52 is fixedly installed on the back side of the mounting plate 2. The bevel gear ring 53 is transmission-connected to the inner end of the displacement mechanism 3. The driving assembly 52 installed on the back side of the mounting plate 2 is started, and the driving assembly 52 generates power to drive the bevel gear ring 53 connected thereto to rotate on the inner side of the side frame 51. Since the side frame 51 is arranged in a ring shape and fixed on the back of the mounting plate 2, it provides support for the rotation of the bevel gear ring 53 When the bevel gear ring 53 rotates, it transmits power to the inner end of the displacement mechanism 3 to drive the displacement mechanism 3 to work. After the displacement mechanism 3 is started, it drives the installation mechanism 6 installed on the front to be displaced. The installation mechanism 6 can install and fix the adjustment mechanism 7. Under the action of the displacement mechanism 3, the adjustment mechanism 7 also moves accordingly. The display screen 4 fixedly installed on the front of the adjustment mechanism 7 moves with the displacement of the adjustment mechanism 7, thereby realizing the position adjustment of the display screen 4, satisfying the functions of splicing and displaying the splicing screen according to different needs, such as unfolding or combining splicing, which is convenient for information display in different scenes.

[0021] Please refer to Figure 2-Figure 5 and Figure 8The mounting mechanism 6 includes a mounting arm 61, which is fixedly mounted on the front of the slider 33.

The outer side of the mounting block 64 is fixedly connected with a connecting shaft 635, and the end of the connecting shaft 635 penetrates the side frame 631 and is fixedly connected with a bridge handrail 636. When the mounting mechanism 6 is working, if the adjusting mechanism 7 is to be installed, first pull the mounting mechanism 631 to install the adjusting mechanism 7. The bridge handrail 636 at the end of the connecting shaft 635 outside the mounting block 64 moves with the connecting shaft 635, driving the clamping block 634 to squeeze the limit spring 633 inside the side frame 631, so that the clamping block 634 is pulled out from the clamping groove 632. At this time, the mounting block 64 can slide freely inside the mounting rail 62. The mounting block 64 is slid into a suitable position in the mounting rail 62, and the bridge handrail 636 is released. The limit spring 633 recovers its deformation, pushing the clamping block 634 to penetrate the side frame 631 again and insert into the clamping groove 632 of the mounting block 64. , the mounting block 64 is fixedly connected to the mounting rail 62. Since the front side of the mounting block 64 is fixedly connected to the back side of the adjusting mechanism 7, the adjusting mechanism 7 can be installed. When the adjusting mechanism 7 needs to be disassembled, the bridge handrail 636 is pulled again to disengage the block 634 from the slot 632. The mounting block 64 loses its limit constraint and can be pulled out along the mounting rail 62, thereby completing the disassembly of the adjusting mechanism 7 conveniently and quickly. The whole process is simple to operate, which is convenient for the installation and disassembly of the adjusting mechanism 7 and the display screen 4.

[0022] Please refer to Figure 2-Figure 6The driving assembly 52 includes a fixed arm 521 and a spur gear ring 522. The fixed arm 521 is fixedly installed at the middle of the lower end of the back of the mounting plate 2. The spur gear ring 522 is fixedly installed at the back of the bevel gear ring 53.

The driving gear 524 and the spur gear ring 522 are meshed and connected. The inner rear end of the mounting frame 1 is fixedly installed with mounting gears arranged in a ring shape at equal intervals. The plate 8 is provided with mounting holes 9 at both ends of the mounting plate 8, and the mounting holes 9 are set as countersunk holes. The displacement mechanism 3 includes side rails 31, and the side rails 31 are arranged in a ring shape with equal spacing and fixedly connected to the outer side of the mounting plate 2. The inner part of the side rail 31 is rotatably connected with a screw rod 32, and the outer surface of the screw rod 32 is threadedly connected with a slider 33, and the slider 33 is slidably connected to the inner part of the side rail 31. The mounting mechanism 6 is installed on the front side of the slider 33, and the inner end of the screw rod 32 is fixedly connected with a bevel gear 34, and the bevel gear 34 and the bevel gear ring 53 Meshing connection, during use, by starting the first motor 523 fixed on the back of the fixed arm 521, the motor output end drives the driving gear 524 to rotate. Because the driving gear 524 is meshed with the spur gear ring 522, the spur gear ring 522 rotates accordingly. The spur gear ring 522 is fixed to the back of the bevel gear ring 53, thereby driving the bevel gear ring 53 to rotate on the inside of the side frame 51. The bevel gear ring 53 is meshed with the bevel gear 34 at the inner end of the screw rod 32, driving multiple screw rods 32 to rotate synchronously, and the slider 33 threadedly connected to the outer surface of the screw rod 32 slides linearly along the track in the side rail 31. The side rails 31 are arranged in a ring shape with equal intervals and fixed on the outside of the mounting plate 2 to provide guidance for the slider 33. A mounting mechanism 6 is installed on the front of the slider 33. As the slider 33 moves, the position of the mounting mechanism 6 changes. Because the mounting mechanism 6 is connected to the adjustment mechanism 7 and the display screen 4, the position of the display screen 4 is finally adjusted to meet the different splicing and display requirements of the splicing screen. The mounting plate 8 at the rear end of the inner side of the mounting frame 1 is provided with a countersunk mounting hole 9 for stable installation of the device.

[0023] Example 2 The splicing screen includes an outer frame 10, and inner splicing screens 12 are equidistantly arranged on the inner side of the outer frame 10, and the inner sides of the inner splicing screens 12 are bonded to each other by sealing strips 11; the splicing screen structure of Example 2 is applied to the process of the splicing seam reduction method of the splicing screen, and the display screen 4 cutting technology of this process can divide the large screen into 1-2 small screens, and the length and width can be freely cut within a certain accuracy according to customer requirements, and the connection method cooperates with the sealing strip 11 to bond and seal the glue, so that each inner splicing screen 12 can be tightly connected, and can meet various layout requirements during application, while reducing the gap between each inner splicing screen 12, which is convenient for actual use.

[0024] The implementation principle of the method and structure for reducing the splicing seam of a spliced ​​screen in an embodiment of the present application is as follows: the device constructs a cooperative working mechanism between a displacement mechanism 3 and a driving mechanism 5, so that during operation, the first motor 523 is started, and the motor output shaft drives the driving gear 524 to rotate, and the driving gear 524 and the spur gear ring 522 are meshed with each other through gear teeth, and the rotational motion of the driving gear 524 is transmitted to the spur gear ring 522, causing it to perform circular motion, and the spur gear ring 522 is mechanically connected to the bevel gear ring 53, and the rotation of the spur gear ring 522 causes the bevel gear ring 53 to rotate synchronously, and the bevel gear ring 53 and the bevel gear 34 constitute a bevel gear 34 transmission pair, and when the bevel gear ring 53 rotates, the driving bevel gear 34 rotates around its own axis, and the bevel gear 34 is rigidly connected to the screw rod 32 The bevel gear 34 rotates to drive the screw rod 32 to rotate synchronously. With this series of transmission components, the first motor 523 realizes the synchronous driving of all the screw rods 32. The screw rod 32 is connected to the slider 33 through a threaded pair. When the screw rod 32 rotates, the slider 33 slides linearly along the predetermined track inside the side frame 51. The slider 33 is fixedly connected to the mounting mechanism 6 and the adjusting mechanism 7. The sliding of the slider 33 pushes the two to move synchronously. The adjusting mechanism 7 is connected to the display screen 4. The displacement of the adjusting mechanism 7 directly drives the display screen 4 to move. Through the coordinated work of the four groups of screw rods 32, the synchronous reciprocating displacement of the four display screens 4 is realized. The display screen 4 can be quickly unfolded or combined and spliced ​​according to actual needs, thereby improving the convenience and efficiency of the spliced ​​display screen 4 operation. The adjustment mechanism 7 plays a key role in the information display in special scenes. When the display screen 4 is moved to the outside by the displacement mechanism 3, the second motor 74 is started, and the motor output shaft directly drives the shaft 72 inside the concave seat 71 to rotate around the fixed axis. The shaft 72 is fixedly connected to the base frame 731. The rotation of the shaft 72 drives the base frame 731 to rotate synchronously. The base frame 731 is connected to the articulated frame 732 through an articulated connection. The rotation of the base frame 731 causes the display screen 4 installed on the front of the articulated frame 732 to rotate accordingly, thereby realizing the lateral angle adjustment of the display screen 4. During operation, the electric push rod 733 is started, and the telescopic rod of the electric push rod 733 is The electric push rod 733 is connected to the articulated frame 732 by an articulation. When the telescopic rod of the electric push rod 733 is extended, it forms an articulated linkage with the articulated frame 732. Based on the lever principle and the mechanical characteristics of the articulated structure, the display screen 4 is pushed to rotate around the hinge point on the base frame 731 to complete the longitudinal angle adjustment of the display screen 4. Taking crowded places such as airports and stations during the Spring Festival as an example, the device can quickly unfold the split screen and adjust the tilt. The display screen 4 can be flexibly rotated horizontally and vertically to ensure that people in different areas can clearly see the content of the display screen 4. Information can be obtained without moving the position of the person, thereby enhancing the application prospect and convenience of use of the device. The mounting mechanism 6 of the present device provides an innovative solution for the installation and removal of the display screen 4. When installing the adjustment mechanism 7 and the display screen 4, the bridge handrail 636 is pulled out, and the bridge handrail 636 is mechanically connected to the connecting shaft 635, driving the connecting shaft 635 to move. The connecting shaft 635 is fixedly connected to the clamping block 634. The movement of the connecting shaft 635 causes the clamping block 634 to squeeze the limit spring 633. The limit spring 633 is elastically deformed and contracted under the force, and the clamping block 634 is immediately separated from the clamping slot 632 and then pulled out from the inside of the mounting rail 62. At this time, the mounting block 64 can be inserted into the inside of the mounting rail 62. After the insertion is completed, the bridge handrail 636 is released, and the limit spring 633 recovers its deformation and resets, and the clamping block 634 is pushed out. The movable card block 634 is reinserted into the card slot 632, and the mutual insertion and limiting of the card block 634 and the card slot 632 are used to realize the stable card connection of the installation block 64 inside the installation rail 62. When the display screen 4 needs to be removed, the bridge handrail 636 is pulled again to drive the card block 634 to squeeze the limiting spring 633, so that the card block 634 is separated from the inner side of the card slot 632, and the installation block 64 loses the limiting constraint and can be pulled out from the inside of the installation slot. In addition, the display screen 4 cutting technology of the present technical solution has advantages, and a large screen can be divided into 1 or 2 small screens. The screen width can be cut within a certain accuracy range according to customer requirements, which meets the diversified layout requirements of different places and is convenient for practical use.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.

Claims

1. A method for reducing the splicing seam of a spliced ​​screen, characterized in that: The steps include: Step 1: Prepare materials. According to the required size of the splicing screen, purchase standard LCD display units with a size range of 46 inches and 55 inches. The diagonal error control range is ±0.1 inches. The thickness of the standard OC LCD glass is between 1.5mm and 2.0mm. Step 2: Polarizer processing: Use a polarizer to accurately cut off the polarizers on the upper and lower sides of the liquid crystal glass. The cutting accuracy of the polarizer is controlled at ±0.05mm to ensure that the edges are neat after cutting, prepare for subsequent cutting, remove unnecessary parts, and avoid interference caused by subsequent cutting; Step 3: Manual tearing: tear off the remaining polarizers on the upper and lower sides of the long LCD screen glass one by one. Since the glass thickness is only 1.5mm, professionals use their experience and skills to slowly tear off the polarizers with uniform force to prevent the glass from breaking. The tearing time for each polarizer is 30 seconds to 60 seconds to ensure the stability and safety of the operation. Step 4: Cutting. Place the LCD screen glass one by one on the cutting machine for cutting. The cutting speed of the cutting machine is set at 5mm / s-10mm / s, and the cutting accuracy is controlled at ±0.1mm. During the cutting process, the operator carefully holds the glass to avoid leakage or the screen failing to light up. The size error of the cut glass is ±0.2mm. Step 5: Timely seal. After the long LCD screen glass is cut into the required size, seal it immediately. Use the sealant for LCD glass and apply it evenly on the edge of the cut glass. The thickness of the glue layer is 0.2mm-0.3mm. Make sure that the sealant completely covers the cut edge to prevent liquid crystal molecules from flowing out and causing leakage. Step 6: Test. Use the motherboard to power on the long LCD screen after cutting and sealing. Focus on the screen display effect to see if there are bright spots, display anomalies, color uniformity deviation, ghosting, or missing lines. Use test equipment and software to measure the screen's brightness, contrast, color saturation and other parameters to ensure that all parameters meet the use standards of the spliced ​​screen.
