Description

[Technical Field]

[0001] The present invention relates to a dual-screen synchronous driving display device, which is a support and driving structure for the dual screens, the driving structure enabling the dual screens to move synchronously but in different directions. [Previous Technology]

[0002] Note that, in general, in places such as public places, department stores or government agencies, in order to achieve the effect of expanding the projection display, multiple display units are often stacked into a display screen (such as a video wall or billboard). The principle of using this large display screen is to use multiple display units to stack and assemble to make the overall size as large as a video wall or billboard. Then, a signal aggregation device is used to convert the input signal according to the number of display units and output it to the display units in different positions, so that the images displayed by the display units in different positions can be pieced together to form a complete image, thereby achieving the purpose of enlarging the image size.

[0003] To suit playback effects or venue requirements, multiple displays can be connected to form a larger display, such as conventional TW 1689808B, a "split-type LED display", in which the two displays are driven by two motors. Due to prolonged use, various mechanical wear and environmental factors can cause load differences, mechanical coupling problems, signal delays or jitter, aging, or performance degradation between the two motors, leading to asynchronous operation. This can result in incomplete closure of the two displays, creating noticeable seams.

[0004] In addition, compared with traditional LEDs, Mini LEDs and Micro LEDs have smaller LED chips, enabling higher pixel density, providing more detailed display effects, and possessing higher brightness and contrast. As a result, giant screens with larger sizes and better image quality have been developed.

[0005] When Mini LED and Micro LED technologies are used on large-size screens, the positional deviation of LED beads can lead to some potential problems, thus affecting image quality. 1. Image misalignment caused by inconsistent bead arrangement: In Mini LED and Micro LED giant screens, thousands of LED beads need to be precisely arranged to achieve uniform brightness and color performance. However, due to tolerances in the manufacturing process, the beads may have slight positional differences in the horizontal or vertical directions. This difference is not obvious on small screens, but when magnified on large screens, it can cause blurred or misaligned edges of the image, resulting in image distortion, especially on moving images or intricate patterns, where the misalignment effect is more pronounced. 2. Edge alignment issues: Giant LED screens are usually composed of multiple modules spliced ​​together. If the arrangement of LED beads between modules is not precise enough, edge alignment between modules may deviate. This phenomenon can cause gaps or overlaps in the image at the module edges, resulting in obvious image discontinuity or blurry transitions, especially in scenarios displaying fast-moving images or requiring detailed images, where this phenomenon significantly reduces the viewing experience. [Summary of the Invention]

[0006] The dual-screen synchronous driving display device of the present invention includes a driving component, at least one first-direction displacement component, at least one second-direction displacement component, two displays, and a guiding component. The driving component has an annular transmission element, a driving wheel, a driven wheel, a driving motor, and a transmission track. The annular transmission element is wound around the driving wheel and the driven wheel, and the annular transmission element is engaged with the driving wheel and the driven wheel. The driving motor is connected to the driving wheel to drive the driving wheel to rotate. When the annular transmission element engaged with the driving wheel is running, the upper part of the annular transmission element and the lower part of the annular transmission element run in opposite directions. The transmission track is disposed between the driving wheel and the driven wheel. The first directional displacement assembly includes a first displacement body, a first display screen fixing part, a first transmission fixing part, and at least one first transmission roller. The first display screen fixing part is located at the bottom of the first displacement body, the first transmission fixing part is located at the top of the first displacement body, and the first transmission fixing part is fixed to the lower part of the annular transmission element. The first transmission rollers are disposed on one side of the first displacement body and can be fitted with the transmission track. The second directional displacement assembly includes a second displacement body, a second display screen fixing part, an extension part, a second transmission fixing part, and at least one second transmission roller. The second display screen fixing part is located at the bottom of the second displacement body, the extension part is located at the top of the second displacement body, the second transmission fixing part is located at the top of the extension part, and the second transmission fixing part is fixed to the upper part of the annular transmission element. The second transmission rollers are disposed on one side of the second displacement body and can be fitted with the transmission track. The displays are respectively fixed to the first display screen fixing part and the second display screen fixing part. The guide assembly has two guide blocks, at least two sliders and a ground track. The guide blocks are fixed to the bottom of the display screens, the sliders are disposed on one side of the guide blocks, and the ground track is buried in the ground. The sliders can be embedded in the ground track.

[0007] Accordingly, the operation of the drive motor can drive the drive wheel and the annular transmission element meshing with the drive wheel to run, and the upper part and the lower part of the annular transmission element move in two opposite directions. In this way, the first direction displacement component and the second direction displacement component can respectively drive the two displays to move in two opposite directions, thereby completing the closing or opening of the two displays.

[0008] Since the present invention drives the drive wheel and the annular transmission element meshing with the drive wheel through a single drive motor, thereby synchronously driving the two displays to close or open, even after long-term use, the two drive motors will not be out of sync due to various problems.

[0009] In a preferred embodiment, the drive assembly further includes a fixed plate, the drive wheel, the driven wheel and the drive motor are respectively disposed on one side of the fixed plate, and the transmission track is formed on one side of the fixed plate.

[0010] In a preferred embodiment, the axial direction of the driving wheel is parallel to the axial direction of the driven wheel, wherein there is a predetermined distance between the driving wheel and the driven wheel to open the annular transmission element and stabilize its tension.

[0011] In a preferred embodiment, each of the first directional displacement components further includes a first anti-fall element, which is disposed on the first displacement body and on the same side as the first transmission rollers. The first transmission rollers are higher than the first anti-fall element, and the first anti-fall element is located below the transmission track. Furthermore, each of the second directional displacement components further includes a second anti-fall element, which is disposed on the second displacement body and on the same side as the second transmission rollers. The second transmission rollers are higher than the second anti-fall element, and the second anti-fall element is located below the transmission track.

[0012] In a preferred embodiment, the first display screen fixing part extends laterally from the bottom of the first displacement body, the first transmission fixing part extends laterally from the top of the first displacement body, the first transmission fixing part is attached to the lower part of the annular transmission element, and the two are connected by a fastener. The second display screen fixing part extends laterally from the bottom of the second displacement body, the extension part extends longitudinally from the top of the second displacement body, the second transmission fixing part extends laterally from the top of the extension part, the second transmission fixing part is attached to the upper part of the annular transmission element, and the two are connected by another fastener.

[0013] In a preferred embodiment, the top surface of each of the two guide blocks has a protrusion for abutting against the bottom of the display screen.

[0014] In a preferred embodiment, the top surface of each of the two guide blocks has a protrusion, and the position of the protrusion on the guide block corresponds to a predetermined distance in front of the transmission track. The protrusion abuts against the bottom rear side of the display screens, so that the bottom of the display screens is tilted forward.

[0015] In a preferred embodiment, the top surface of each of the sliders has an assembly plate for fixing to the rear side of the guide blocks.

[0016] In a preferred embodiment, each of the displays has an outer frame, a plurality of longitudinal frames, a side frame, a sensor, a plurality of display units and a plurality of elastic members. The longitudinal frames and the side frame are fixed to the front side of the outer frame, and the side frame is located on the edge opposite to the other display. The display units are adjustablely fixed to the front side of the longitudinal frames and the side frame. The display units are arranged in a matrix, and the display units fixed to the side frame protrude from the outer frame and the side frame towards the opposite side of the other display. When the displays are closed, the display units on the opposite sides contact each other, and the display units are interleaved and bound to two adjacent longitudinal frames using the elastic members.

[0017] In a preferred embodiment, the present invention further includes a controller electrically connected to the drive motor and at least two sensors, wherein the sensors are disposed on the frame and are used to sense objects passing through or obstructing the display screens.

[0018] Furthermore, the dual-screen synchronous driving display device of the present invention also allows for convenient adjustment of the display screen units. Since only the display screen units on the opposite side are in contact when the left and right displays are closed, when there is a positional difference between the display screen units on the left and right sides, only a slight adjustment of the position of the display screen units is needed. And since the display screen units are fixed to the vertical frame or the side frame by magnetic attraction, the position adjustment of the display screen units can be achieved simply by moving their positions.

The actual orientation of the feature structures may change depending on the placement angle or the user's position, and should not be used to limit the scope equally covered herein. The term "front side" in this document refers to the side of the display screen facing the viewer (equivalent to the same side as the displayed image), while the term "back side" is the opposite side of "front side."

[0024] Please refer to Figure 1, which is a front view schematic diagram of the dual-screen synchronous driving display device 10 of the present invention. As shown in the figure, the dual-screen synchronous driving display device 10 includes a driving component 20, three first-direction displacement components 30, three second-direction displacement components 40, two display screens 50, a guiding component 60, and a controller 70. The two display screens 50 are respectively disposed on the first-direction displacement components 30 and the second-direction displacement components 40. The driving component 20 is used to drive the first-direction displacement components 30 and the second-direction displacement components 40 to move in two opposite directions, so that the two display screens 50 open or close opposite each other. The guiding component 60 is used to guide the displacement of the two display screens 50 so that their displacement direction does not sway or deviate.

[0025] Regarding the drive assembly 20, it includes an annular transmission element 21, a driving wheel 22, a driven wheel 23, a fixed plate 24, a transmission track 25, and a drive motor 26. The annular transmission element 21 can be a chain, belt, or synchronous belt, etc., and is wound around the driving wheel 22 and the driven wheel 23. The annular transmission element 21 can mesh with the surface of the driving wheel 22 and the surface of the driven wheel 23. The driving wheel 22 and the driven wheel 23 are disposed on the front side of the fixed plate 24, and the axial direction of the driving wheel 22 is parallel to the axial direction of the driven wheel 23. The driving wheel 22 and the driven wheel 23 maintain a predetermined distance to support the annular transmission element 21 and stabilize its tension. The transmission track 25 is formed on the front side of the fixed plate 24 and is located between the driving wheel 22 and the driven wheel 23. The drive motor 26 is fixed to the fixed plate 24 and connected to the drive wheel 22. The drive motor 26 drives the drive wheel 22 to rotate, causing the annular transmission element 21 meshing with it to run, thereby driving the driven wheel 23 to rotate as well. When the annular transmission element 21 is running, its upper part 211 and lower part 212 run in opposite directions. It should be noted that the upper part 211 and lower part 212 are not fixed areas on the annular transmission element 21, but are based on their relative positional relationship during operation. For example, if the annular transmission element 21 is a ring chain, any specific point during operation will first pass through the upper part 211, then enter the lower part 212, and then return to the upper part 211, forming a cycle. Therefore, the distinction between the upper part 211 and lower part 212 is based on their positional relationship during operation, rather than being fixed to a specific part of the annular transmission element 21.

[0026] Regarding the first directional displacement component 30, please refer to Figures 2 and 3. Figure 2 is an exploded perspective view of the first directional displacement component 30, and Figure 3 is a side view view of the first directional displacement component 30. As shown in the figures, each first directional displacement component 30 has a first displacement body 31, a first display screen fixing part 32, a first transmission fixing part 33, two first transmission rollers 34, and a first anti-fall element 35. The first display screen fixing part 32 is a platform extending laterally from the bottom of the first displacement body 31 to the rear, and the first transmission fixing part 33 is a platform extending laterally from the top of the first displacement body 31 to the front. Through the first transmission fixing part 33, its platform is attached to the lower part 212 of the annular transmission element 21, and the two are connected by fasteners. Each first transmission roller 34 and the first anti-fall element 35 are disposed on the rear side of the first displacement body 31, and each first transmission roller 34 is higher than the first anti-fall element 35. Each first transmission roller 34 is located above the transmission track 25 and can slide on the transmission track 25. The first anti-fall element 35 is located below the transmission track 25.

[0027] Regarding the second directional displacement component 40, please refer to Figures 4 and 5. Figure 4 is an exploded perspective view of the second directional displacement component 40, and Figure 5 is a side view view of the second directional displacement component 40. As shown in the figures, each second directional displacement component 40 has a second displacement body 41, a second display screen fixing part 42, an extension part 43, a second transmission fixing part 44, two second transmission rollers 45, and a second anti-fall element 46. The second display screen fixing part 42 is a platform extending laterally from the bottom of the second displacement body 41 to the rear. The extension part 43 is a bracket extending longitudinally from the top of the second displacement body 41. The second transmission fixing part 44 is a platform extending laterally from the top of the extension part 43 to the front. The platform is attached to the upper part 211 of the annular transmission element 21, and the two are connected by fasteners. Each second transmission roller 45 and the second anti-fall element 46 are disposed on the rear side of the second displacement body 41, and each second transmission roller 45 is higher than the second anti-fall element 46. Each second transmission roller 45 is located above the transmission track 25 and can slide on the transmission track 25. The second anti-fall element 46 is located below the transmission track 25.

[0028] In this embodiment, both the first directional displacement component 30 and the second directional displacement component 40 have two sets (as shown in Figure 1). Please refer to Figures 3 and 5, where the two sets of first directional displacement components 30 are fixed above one of the display screens 50, and the two sets of second directional displacement components 40 are fixed above the other display screen 50. The number of sets of first directional displacement components 30 or second directional displacement components 40 is increased or decreased according to the size and weight of the display screen 50 and safety requirements.

[0029] Regarding the display screen 50, there are two sets, which are respectively fixed below the first display screen fixing part 32 and the second display screen fixing part 42. In one example, the first display screen fixing part 32 or the second display screen fixing part 42 is attached to the top of the display screen 50 and the two are connected by fasteners.

[0030] Please refer to Figure 6, which is a schematic cross-sectional view of the display screen 50. As shown in the figure, each display screen 50 has an outer frame 51, a plurality of longitudinal frames 52, a side frame 53, a sensor 54, a plurality of display screen units 55, and a plurality of elastic members 56. Each longitudinal frame 52 and side frame 53 is fixed to the front side of the outer frame 51, and the side frame 53 is located on the edge opposite to the other display screen 50. The opposite side of the two display screens 50 refers to the contact side when the two display screens 50 are closed. In one example, when the two display screens 50 are closed, the right side of the left display screen 50 will contact the left side of the right display screen 50, that is, the right side of the left display screen 50 and the left side of the right display screen 50 are the opposite sides of the two display screens 50. Sensor 54 is mounted on the side frame 53 and is used to sense objects passing through or obstructing the space between the two displays 50. Sensor 54 can be a photoelectric sensor, pressure sensor, ultrasonic sensor, capacitive sensor, magnetic sensor, infrared sensor, or laser sensor. Each display unit 55 is magnetically fixed to each longitudinal frame 52 and side frame 53. The display units 55 are arranged in a matrix, and each display unit 55 fixed to the side frame 53 protrudes from the outer frame 51 and side frame 53 on the opposite side of the display 50. In one example, when the two displays 50 are closed, the display units 55 of one display 50 fixed to the side frame 53 will contact the display units 55 of the other display 50 fixed to the side frame 53, so that there is a gap between the outer frames 51 or side frames 53 of the two displays 50. Each display unit 55 is further secured to two adjacent vertical frames 52 by a plurality of elastic members 56. More specifically, the rear side of the display unit 55 can be secured by two elastic members 56, and the two elastic members 56 are crossed and then secured to two adjacent vertical frames 52.

[0031] Regarding the guide assembly 60, please refer to Figure 7, which is an exploded perspective view of the guide assembly 60. As shown in the figure, the guide assembly 60 has two guide blocks 61, a plurality of sliders 62, and a ground track 63. Each of the two guide blocks 61 has a protrusion 611 on its top surface. The two guide blocks 61 are respectively fixed to the bottom of the two display screens 50, and each outer frame 51 abuts against the front side of the protrusion 611. Each slider 62 has an assembly plate 621 on its top surface. The assembly plate 621 is used to fix the guide block 61 to the rear side (corresponding to the side away from the first display screen fixing part 32 or the second display screen fixing part 42), and each guide block 61 can fix one or more sliders 62. The ground track 63 is buried in the ground, and each slider 62 can be embedded in the ground track 63. The two guide blocks 61 can move the sliders 62 in the ground track 63 as the two display screens 50 are displaced.

[0032] It is worth mentioning that, please refer to Figure 8, which is a side view of the display screen 50 and the guide assembly 60. Since each outer frame 51 abuts against the front side of the protrusion 611, the protrusion 611 can be used to limit the forward and backward swing of the two display screens 50. In other words, the protrusion 611 abuts against the rear side of each outer frame 51, so the two display screens 50 cannot swing backward. In this embodiment, the position of the protrusion 611 on the guide block 61 corresponds to a predetermined distance in front of the transmission rail 25, so that the bottom of the two display screens 50 is tilted forward (in the figure, the tilt angle shown is relatively large for the sake of clarity, but in practice, the bottom of a six- to seven-foot-long display screen 50 may only be tilted forward by one centimeter). In this way, the top center of gravity of the two display screens 50 is oriented towards the transmission rail 25, so as to avoid the two display screens 50 from swinging back and forth and increase the stability of the left and right displacement of the two display screens 50.

[0033] Regarding the controller 70, please refer to Figure 9, which is a block diagram of the controller 70. As shown in the figure, the controller 70 is electrically connected to the drive motor 26 and each sensor 54. The controller 70 can control the position, speed, direction, acceleration, and torque of the drive motor 26, so that the drive motor 26 can accurately run the ring transmission element 21 through the drive wheel 22 to drive each first direction displacement component 30 and each second direction displacement component 40, thereby realizing the opening or closing of the two displays 50. The controller 70 can also receive the sensing signals from each sensor 54 and issue control commands to the drive motor 26 based on the received signals.

[0034] In the implementation and operation of the present invention, please refer to Figure 10, which is a schematic diagram of the dual-screen closure of the present invention. As shown in the figure, in one embodiment, the controller 70 controls the drive motor 26 to rotate clockwise, thereby driving the drive wheel 22 to rotate clockwise, so that the annular transmission element 21 meshing with the drive wheel 22 runs clockwise. Therefore, the upper part 211 of the annular transmission element 21 moves to the right, and its lower part 212 moves to the left. In this way, the second direction displacement component 40 drives the left display screen 50 to move to the right, and the first direction displacement component 30 drives the right display screen 50 to move to the left, so that the two display screens 50 close together to form a larger display screen. Conversely, please refer to Figure 11, which is a schematic diagram of the dual-screen opening implementation of the present invention. As shown in the figure, in one embodiment, the controller 70 controls the drive motor 26 to reverse, thereby driving the drive wheel 22 to reverse, so that the annular transmission element 21 meshing with the drive wheel 22 runs counterclockwise. Therefore, the upper part 211 of the annular transmission element 21 moves to the left, and its lower part 212 moves to the right. In this way, the second direction displacement component 40 drives the left display screen 50 to move to the left, and the first direction displacement component 30 drives the right display screen 50 to move to the right, so that the two display screens 50 are opened opposite each other.

[0035] In summary, the dual-screen synchronous driving display device provided by the present invention has the following advantages compared with other conventional technologies: 1. It has a fall prevention function. During use, the display screen 50 may be affected by external forces (such as collisions, earthquakes, etc.), causing the first transmission roller 34 to swing or be impacted and disengage from the transmission track 25. When it is about to disengage from the transmission track 25, the first fall prevention element 35 can abut against the bottom surface of the transmission track 25, thus preventing the first transmission roller 34 from completely disengaging from the transmission track 25, thereby preventing the display screen 50 from falling. In addition, since the position of the protrusion 611 on the guide block 61 corresponds to a predetermined distance in front of the transmission track 25, the bottom of the two display screens 50 is tilted forward, and the top center of gravity of the two display screens 50 is facing the transmission track 25. Therefore, the two display screens 50 can be prevented from swinging back and forth, increasing the stability of the left and right displacement of the two display screens 50, and further preventing the first transmission roller 34 from completely disengaging from the transmission track 25. 2. The purpose of the display unit 55 can be easily adjusted. When the left and right display screens 50 are closed, only the display units 55 on the side frame 53 will contact the display units 55 of the other display screen 50 fixed on the side frame 53. Therefore, when there is a positional difference between the display units 55 on the left and right display screens 50, only a slight adjustment of the position of each display unit 55 is needed. Because each display unit 55 is fixed to each longitudinal frame 52 or each side frame 53 by magnetic attraction, the position of each display unit 55 can be adjusted simply by moving its position. 3. Foreign objects in the ground track 63 can be quickly removed. When there are foreign objects in the ground track 63, causing the sliders 62 to be unable to move, a safety inspection is required. Since the ground track 63 is located behind the guide block 61 and the two display screens 50, there are fewer blind spots during the safety inspection, and foreign objects in the ground track 63 can be found and removed more quickly. 4. Anti-pinch design for the display screen 50. The controller 70 can receive sensing signals from each sensor 54. When each sensor 54 detects an object (person or obstacle) passing through or blocking the two displays 50, it can control the drive motor 26 to stop to prevent the two displays 50 from colliding with people or obstacles when they are aligned, thus preventing damage to the displays 50 due to collision and preventing people from being pinched by the two displays 50. 5. Silent design. The first transmission roller 34 and the second transmission roller 45 can use Teflon (PTFE, polytetrafluoroethylene) wheels, or be covered with a Teflon shell. In this way, when the first transmission roller 34 or the second transmission roller 45 slides on the transmission track 25, due to the properties of Teflon such as reducing the coefficient of friction, reducing resonance, and sound absorption, it can effectively reduce the noise generated by the sliding friction and vibration of the first transmission roller 34 or the second transmission roller 45 on the transmission track 25.
