Description

Technical Field

[0001] This invention relates to the field of display screen assembly technology, and in particular to a display mechanism and a spliced ​​display screen. Background Technology

[0002] Currently, most common splicing displays on the market are PCB-based displays. However, due to their low precision, susceptibility to heat deformation, and low flatness, PCB-based displays can no longer meet market demands.

[0003] Glass substrate displays possess high precision, resistance to deformation, and high flatness that PCB-based displays lack, making them well-suited to meet market demands. However, glass substrate displays are hard yet brittle, and during splicing, they are prone to damage or even breakage, resulting in losses.

[0004] To address the aforementioned issues, it is necessary to develop a display mechanism and a splicing display screen to solve the problem that glass substrate displays are easily damaged or even broken due to collisions or pressure during the splicing process. Summary of the Invention

[0005] The purpose of this invention is to provide a display mechanism and splicing display screen that can achieve ultra-narrow bezels without damaging the display components.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A display mechanism, comprising:

[0008] Mounting plate;

[0009] The display component is fixedly mounted on the mounting plate. The display component includes at least one display. The orthographic projection of the mounting plate onto the plane where the display component is located is within the outer contour of the display component.

[0010] Four adjustment components are provided, each including an adjustment element, an elastic element, and an adjustment screw. Each adjustment element is disposed on one side of the mounting plate and can be close to or away from the side. The two ends of the elastic element respectively abut against the adjustment element and the side of the mounting plate. The adjustment screw passes through the adjustment element and is threadedly connected to the mounting plate.

[0011] Preferably, the adjustment assembly further includes a locking screw that passes through the adjustment member and is threadedly connected to the adjustment member. When the locking screw is screwed into the adjustment member, the locking screw abuts against the mounting plate.

[0012] Preferably, the adjusting assembly includes two adjusting screws, which are respectively disposed at both ends of the adjusting member.

[0013] Preferably, the side wall of the mounting plate is provided with a first guide groove, the adjusting member is provided with a second guide groove, and the two ends of the elastic member extend into the first guide groove and the second guide groove, respectively.

[0014] Preferably, it further includes at least one control component, the control component including a control circuit board, the control circuit board being fixedly disposed on the side of the mounting plate opposite to the display component, and each control circuit board being electrically connected to one of the displays via a flexible circuit board.

[0015] Preferably, the mounting plate is provided with a first clearance portion, which is used to avoid the flexible circuit board.

[0016] Preferably, the display assembly further includes a support plate, the at least one display is fixedly disposed on the support plate, and the support plate is fixedly disposed on the mounting plate.

[0017] Preferably, the system further includes frame adhesive, which is used to bond and fix each display to the support plate, and the support plate to the mounting plate.

[0018] A splicing display screen includes a plurality of the aforementioned display mechanisms and a back plate. The plurality of display mechanisms are fixedly disposed on the back plate, and the adjusting members of adjacent display mechanisms abut against each other.

[0019] Preferably, each of the mounting plates of the display mechanism is provided with a magnetic element, and the display mechanism is magnetically attached to the back plate by the magnetic element.

[0020] The beneficial effects of this invention are:

[0021] This invention provides a display mechanism and a splicing display screen. In this display mechanism, the display components are mounted on a mounting plate. An operator can change the distance between the adjusting components and the mounting plate by rotating adjusting screws, allowing the adjusting components to extend beyond the edge of the display components. An elastic element drives the adjusting components to always abut against the screw caps of the adjusting screws, keeping the adjusting components in a stable state and improving adjustment accuracy. Once the operator has adjusted all four adjusting components to extend beyond the edge of the display components, the display mechanism can be spliced.

[0022] When multiple display units are spliced ​​together to form a complete video wall, adjacent display units abut against each other through their respective adjustment mechanisms. Even if collisions or squeezing occur between adjacent display units, they will only happen between the adjustment mechanisms and will not damage the display units. Furthermore, operators can adjust the gap between two adjacent display units according to actual needs, achieving ultra-narrow bezels without damaging the display components.

[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Currently, most common splicing displays on the market are PCB-based displays. Individual PCB-based displays are positioned using locating pins and connected to splicing units via connectors. These splicing units are then assembled into a final large screen using locating pins and spring locks. Because of the inherent toughness of the PCB substrate, adjacent splicing units will not shatter or be damaged even in collisions or compression, resulting in minimal seams between PCB-based displays. However, PCB-based displays, due to their low precision, susceptibility to heat deformation, and relatively low flatness, can no longer meet market demands.

[0037] Glass substrate displays possess high precision, resistance to deformation, and high flatness that PCB-based displays lack, making them well-suited to meet market demands. However, glass substrate displays are hard yet brittle, and during splicing, they are prone to damage or even breakage, resulting in losses.

[0038] To address this problem, the present invention provides a display mechanism and a splicing display screen that can achieve ultra-narrow bezels without damaging the display components. A detailed description follows.

[0039] One embodiment of the present invention provides a display mechanism. For example... Figures 1-4As shown, the display mechanism includes a mounting plate 1, a display component 2, and four adjustment components 3. The display component 2 is fixedly mounted on the mounting plate 1 and includes at least one display 21. The orthographic projection of the mounting plate 1 onto the plane of the display component 2 is within the outer contour of the display component 2. The adjustment components 3 include adjustment members 31, elastic members 32, and adjustment screws 33. Each adjustment member 31 is located on one side of the mounting plate 1 and can be close to or away from the side. The two ends of the elastic member 32 abut against the adjustment member 31 and the side of the mounting plate 1, respectively. The adjustment screws 33 pass through the adjustment member 31 and are threadedly connected to the mounting plate 1.

[0040] See Figure 1 and Figure 2 In this embodiment, the display component 2 includes only one display 21.

[0041] See also Figures 1-2 and combined Figure 4 In this display mechanism, the display component 2 is mounted on the mounting plate 1. The operator can change the distance between the adjusting member 31 and the mounting plate 1 by rotating the adjusting screw 33, allowing the adjusting member 31 to extend beyond the edge of the display component 2. The elastic member 32 drives the adjusting member 31 to always abut against the screw cap of the adjusting screw 33, keeping the adjusting member 31 in a stable state and improving the accuracy of adjustment. Once the operator has adjusted the adjusting members 31 of all four adjusting components 3 to extend beyond the edge of the display component 2, the display mechanism can be assembled.

[0042] When multiple display units are spliced ​​together to form a complete splicing display screen, adjacent display units abut against each other through their respective adjustment parts 31. Even if collisions or squeezing occur between adjacent display units, they will only happen between the adjustment parts 31 and will not damage the display 21. Furthermore, the operator can adjust the gap between two adjacent display units according to actual needs through the adjustment parts 31, achieving ultra-narrow bezels without damaging the display components 2.

[0043] After the operator adjusts the position of the adjusting component 31 into place using the adjusting screw 33, the position of the adjusting component 31 needs to be fixed to prevent the two display components 2 from squeezing and pushing each other when splicing, which could cause the display 21 to collide. Figure 2 As shown, to solve this problem, the adjustment assembly 3 also includes a locking screw 34, which passes through the adjustment member 31 and is threadedly connected to the adjustment member 31. When the locking screw 34 is screwed into the adjustment member 31, the locking screw 34 abuts against the mounting plate 1.

[0044] The operator can rotate the locking screw 34 to bring it close to the mounting plate 1 and make it abut against the mounting plate 1, thereby preventing the adjusting member 31 from getting close to the mounting plate 1. Together with the adjusting screw 33, the adjusting member 31 is locked, which can protect the display component 2 from being squeezed or collided during splicing.

[0045] Preferably, the adjustment component 3 includes two adjustment screws 33, which are respectively disposed at both ends of the adjustment member 31. Since two points determine a straight line, the operator can change the distance between the adjustment member 31 and the mounting plate 1 using the two adjustment screws 33. Moreover, if there is a small angle difference between the display component 2 and the mounting plate 1, the operator can also adjust the distance between the two ends of the adjustment member 31 and the mounting plate 1 using the two adjustment screws 33, so that each adjustment member 31 extends parallel beyond the edge of the display component 2, ensuring that the edges of adjacent display components 2 are parallel when spliced.

[0046] Similarly, the adjustment component 3 also includes two locking screws 34, which are respectively located at both ends of the adjustment component 31.

[0047] Preferably, the sidewall of the mounting plate 1 is provided with a first guide groove, the adjusting member 31 is provided with a second guide groove, and both ends of the elastic member 32 extend into the first guide groove and the second guide groove, respectively. The sidewalls of the first guide groove and the second guide groove can play a certain limiting role on the elastic member 32, preventing the elastic member 32 from bending during compression, providing a certain guiding role for the compression process of the spring, and reducing the failure rate of the adjusting assembly 3.

[0048] It is understandable that the elastic element 32 is a spring, which is sleeved on the adjusting screw 33 so that the elasticity can be further guided by the adjusting screw 33.

[0049] In one embodiment, the display mechanism further includes at least one control component 4. For example... Figure 2 As shown, taking a control component 4 as an example, the control component 4 includes a control circuit board 41, which is fixedly mounted on the side of the mounting plate 1 away from the display component 2. Each control circuit board 41 is electrically connected to a display 21 through a flexible circuit board 42. The control circuit board 41 controls the display screen of the display 21 through the flexible circuit board 42, so that the multiple display units spliced ​​together can completely display the image to be displayed.

[0050] Since the flexible circuit board 42 needs to bypass the mounting plate 1 to connect the display component 2 and the control circuit board 41, in order to prevent the flexible circuit board 42 from affecting the function of the adjustment component 3, the mounting plate 1 is provided with a first clearance part 12, which is used to avoid the flexible circuit board 42. The first clearance part 12 can be a clearance groove or a clearance hole.

[0051] Understandably, mounting plate 1 needs to be able to be drilled to install adjustment component 3, and mounting plate 1 is used to fix the display mechanism during splicing, so it needs to be able to install a fixing structure. Therefore, mounting plate 1 needs to have high hardness, not be easily deformed, and be machinable, so mounting plate 1 is made of metal materials such as aluminum alloy.

[0052] like Figure 2 As shown, the display mechanism also includes frame adhesive 23, which is used to bond and fix the display 21 to the mounting plate 1. Using frame adhesive 23 for bonding and fixing provides a stable fixation effect while minimizing the area to be fixed. This minimizes the risk of the display component 2 and mounting plate 1 becoming misaligned due to varying adhesive thickness at different locations during bonding, thus reducing the impact on the final splicing effect.

[0053] Another embodiment of the present invention provides a display mechanism. This display mechanism is based on the display mechanism provided in the foregoing embodiments, wherein each display component 2 includes at least two displays 21, such as... Figure 3 and Figure 4 As shown.

[0054] When the display assembly 2 is fixedly mounted on the mounting plate 1, although the mounting plate 1 has high rigidity, it can still deform slightly. Since the display 21 of the display assembly 2 is a glass substrate display screen, even slight deformation can easily cause adjacent displays 21 to squeeze against each other and cause damage. To solve this problem, the display assembly 2 also includes a support plate 22, on which several displays 21 are fixedly mounted. The support plate 22 is fixedly mounted on the mounting plate 1. The support plate 22 is made of glass and provides good support for the displays 21.

[0055] The display mechanism also includes at least two control components 4, each control component 4 including a control circuit board 41, which is fixedly disposed on the side of the mounting plate 1 away from the display component 2. Each control circuit board 41 is electrically connected to a display 21 via a flexible circuit board 42.

[0056] In order to accurately install several displays 21 of each display component 2 onto the support plate 22, so that the gap between adjacent displays 21 is small and the displays 21 do not collide, there are marks on the displays 21 and the support plate 22 made by an exposure process (the positional accuracy can reach ±1μm). The high-precision camera identifies and aligns them together.

[0057] The support plate 22 is provided with a second clearance portion 221, which is used to avoid the flexible circuit board 42. The second clearance portion 221 can be a clearance groove or a clearance hole.

[0058] like Figure 4As shown, the display mechanism also includes frame adhesive 23, which is used to bond and fix each display 21 to the support plate 22, and to bond and fix the support plate 22 to the mounting plate 1.

[0059] In this embodiment, each display component 2 includes 12 displays 21. The 12 displays 21 are glued and fixed to the support plate 22 by frame adhesive 23 and arranged in 3 rows, with 4 displays 21 in each row. The support plate 22 is glued and fixed to the mounting plate 1 by frame adhesive. 12 control circuit boards 41 are fixedly disposed on the mounting plate 1 on the back side of the display component 2, and each control circuit board 41 is electrically connected to the display 21 through a flexible circuit board 42. The flexible circuit board 42 passes through the mounting plate 1 and the support plate 22 respectively through a first clearance part 12 and a second clearance part 221. Four adjustment components 3 are movably disposed around the mounting plate 1 by adjusting screws 33. The operator can change the distance between the adjustment component 31 and the mounting plate 1 by adjusting screws 33 and lock it by locking screws 34.

[0060] After the operator has adjusted the multiple display mechanisms, the multiple display mechanisms can be magnetically attached to the back panel and arranged tightly by their respective adjustment parts 31 to form a complete splicing display screen.

[0061] An embodiment of the present invention also provides a splicing display screen. The splicing display screen includes multiple display mechanisms and a back panel. The display mechanisms are fixedly mounted on the back panel, and the adjusting members 31 of adjacent display mechanisms abut against each other. The display mechanisms, with their adjusting members 31 positioned correctly, are assembled one by one onto the back panel to form a complete splicing display screen.

[0062] The size of the seam between two adjacent display units depends on the sum of the distances of their respective adjusting components 31 beyond the display assembly 2, and the adjusting component 3 can precisely adjust this distance. Specifically, for example, if the adjusting screw 33 is M3, the pitch is 0.35mm. That is, for every revolution of the adjusting screw 33, the adjusting component 31 moves outward by 0.35mm. If each 10° rotation of the adjusting screw 33 is used as a increment, then for every 10° rotation of the adjusting screw 33, the adjusting component 31 will move by 9.7μm. Using screws with even smaller pitches, such as M1 or M2, the adjustment precision can be even higher. The seam between two adjacent display units can be precisely adjusted according to actual needs, achieving an ultra-narrow seam.

[0063] Furthermore, each mounting plate 1 of the display mechanism is equipped with magnetic components, allowing the display mechanism to be magnetically attached to the back plate. This magnetic attachment eliminates the need for a separate fixing structure on the back plate, significantly simplifying its structure. Additionally, the display mechanisms can be installed piece by piece, allowing for adjustments to their specific positions based on actual needs. This prevents the back plate's fixing structure from becoming incompatible with the display mechanism due to manufacturing errors or other specific requirements, greatly improving the back plate's applicability.

[0064] In this embodiment, the control circuit board 41 and the display 21 are respectively disposed on both sides of the mounting plate 1 and electrically connected through a flexible circuit board 42. The display 21 is bonded and fixed to the mounting plate 1 by frame adhesive 23. The flexible circuit board passes through the mounting plate 1 through the first clearance part 12. Four adjustment components 3 are movably disposed around the mounting plate 1 by adjusting screws 33. The operator can change the distance between the adjustment component 31 and the mounting plate 1 by adjusting screws 33 and lock them by locking screws 34.

[0065] After the operator has adjusted the multiple display mechanisms, the multiple display mechanisms can be magnetically attached to the back panel and arranged tightly by their respective adjustment parts 31 to form a complete splicing display screen.

[0066] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
