Abstract

This application discloses a display device, comprising: at least two display units, which are interconnected; and a power transmission line, including a main bus and at least two branch wires, one end of each branch wire being electrically connected to the main bus and the other end of each branch wire being electrically connected to a different display unit. This application, by setting at least two branch wires on the main bus, with each branch wire electrically connecting different display units, allows current to be transmitted between the interconnected display units via the main bus. When the interconnected display units become misaligned, the main bus can bend to a certain extent to counteract the adverse effects of this misalignment.

[0002] In recent years, Mini LED (direct display) large screens are generally composed of multiple display units. Currently, each display unit in the industry is equipped with a power cord with a connector. During installation, the power cords between adjacent display units need to be plugged in. Each display unit needs to be equipped with a set of power cords with connectors. Since the stability of the plug-in connection between adjacent display units is uncontrollable, it is easy to cause poor contact and lead to the risk of power outage.

[0030] This application provides a display device. The details are described below.

[0031] Figure 1 This is a schematic diagram of the structure of the display device provided in the embodiments of this application; Figure 2 A schematic diagram of the cabinet frame, control board, and power transmission lines of the display device provided in the embodiments of this application; Figure 3 This is a schematic diagram of the cabinet frame and power transmission lines of the display device provided in an embodiment of this application. Figures 1 to 3 As shown, this application embodiment provides a display device 1000, which includes at least two display units 1100, which are spliced ​​together. The display device 1000 also includes a power transmission line 1200, which is used to supply power to the display units 1100. The power transmission line 1200 includes a bus 1210 and at least two branch lines 1220. One end of each branch line 1220 is electrically connected to the bus 1210, and the other end of each branch line 1220 is electrically connected to different display units 1100. Different display units 1100 are connected in parallel in the circuit of the power transmission line 1200 through the branch lines 1220.

[0032] This application provides at least two branch wires 1220 on the bus 1210, each branch wire 1220 electrically connecting different display units 1100. The display units 1100 are connected to each other and current is transmitted through the bus 1210. Since the bus 1210 has a certain degree of flexibility, when the display units 1100 are misaligned, the bus 1210 can bend to a certain extent to counteract the adverse effects caused by the misalignment of the display units 1100.

[0033] Since the display unit 1100 and the bus 1210 are indirectly connected through the branch wire 1220, and the branch wire 1220 also has a certain degree of flexibility, the adverse effects of the deformation of the bus 1210 on the interconnected display unit 1100 and the branch wire 1220 can be offset, thereby achieving stable power supply between the interconnected display units 1100. This avoids the problem of unstable power supply between interconnected display units 1100 achieved by setting a docking plug 1231 on the display unit 1100 for mutual plugging in in the prior art, and solves the problem of unstable power supply between the existing interconnected display units 1100.

[0034] The other ends of at least two branch wires 1220 are distributed sequentially along the extension direction of the bus 1210 to electrically connect with different display units 1100, thereby powering different display units 1100. By connecting different display units 1100 with at least two branch wires 1220 distributed at different locations, the overlapping of different branch wires 1220 during the extension process can be avoided, thus avoiding safety hazards during power supply. At the same time, the length of a single branch wire 1220 can be shortened, saving costs and internal space of the display device 1000. Alternatively, along the extension direction of the bus 1210, the other ends of at least two branch wires 1220 can be connected to positions on the bus 1210 that extend at the same distance.

[0035] Specifically, the display device 1000 may include two display units 1100, and the power transmission line 1200 may include a bus 1210 and two branch wires 1220 distributed along the extension direction of the bus 1210. The bus 1210 may extend along the splicing direction of the two display units 1100, and the two branch wires 1220 may each connect to a different display unit 1100. Of course, the number of display units 1100 may be multiple, and the number of branch wires 1220 may be less than the number of display units 1100. In this case, multiple power transmission lines 1200 can be set to achieve power transmission to all display units 1100.

[0036] In some embodiments, the other ends of the plurality of branch wires 1220 are distributed at equal intervals along the extension direction of the bus 1210. The spacing between the other ends of two adjacent branch wires 1220 can be determined according to the position of the connection point of the branch wires 1220 on the two display units 1100 that are spliced ​​together.

[0037] In some other embodiments, the other ends of at least two branch wires 1220 may be connected to the same location on the bus 1210.

[0038] Figure 6 This is a schematic diagram of the power transmission line structure provided in an embodiment of this application. Figure 6As shown, the bus 1210 includes a first live wire 1211 and a first neutral wire 1212, and the branch wires 1220 include a second live wire and a second neutral wire. The first live wire 1211 of the bus 1210 and the second live wires of each branch wire 1220 are electrically connected to each other. The first neutral wire 1212 of the bus 1210 and the second neutral wires of each branch wire 1220 are electrically connected to each other. The second live wires and the second neutral wires of the branch wires 1220 are electrically connected to the display unit 1100 respectively.

[0039] Optionally, a branch connector 1230 is provided on the bus 1210, and one end of the branch wire 1220 is electrically connected to the bus 1210 through the branch connector 1230. In this embodiment, a branch connector 1230 is provided on the bus 1210. The branch connector 1230 includes a wire and a covering material for the wire. The wire disposed in the branch connector 1230 electrically connects the bus 1210 and the branch wire 1220. Since the outer insulating protective sleeve of the bus 1210 needs to be peeled off during the electrical connection process between the branch wire 1220 and the bus 1210, the branch connector 1230 needs to cover the location where the bus 1210 and the branch wire 1220 are electrically connected to avoid risks such as leakage. It is easy to understand that the covering material of the branch connector 1230 can be an insulating material.

[0040] At least one branch wire 1220 is connected to the same branch connector 1230. Besides preventing leakage, the branch connector 1230 also secures the branch wire 1220 on the branch connector 1230, preventing the connection between the branch wire 1220 and the main bus 1210 from becoming loose or detaching. Furthermore, since the branch connector 1230 is used to secure the branch wire 1220, the direction in which the branch wire 1220 extends from the branch connector 1230 can also be secured by the branch connector 1230.

[0041] Specifically, one branch wire 1220 can be connected to a branch connector 1230; or, two or more branch wires 1220 can be connected to a branch connector 1230. The direction in which the branch wire 1220 extends from the branch connector 1230 can be along the extension direction of the bus 1210 or in the opposite direction to the extension direction of the bus 1210, so as to avoid reducing the continuous space within the display device 1000 when the direction in which the branch wire 1220 extends from the branch connector 1230 forms an angle with the extension direction of the bus 1210.

[0042] Figure 4 Provided for the embodiments of this application Figure 3 A magnified view of a portion of region A in the image. (See image below.) Figure 4As shown, optionally, the branch connector 1230 is provided with a grounding terminal 1240 electrically connected to the bus 1210. The grounding terminal 1240 is used to electrically connect to the display unit 1100 so that the display unit 1100 is grounded. The grounding terminal 1240 and the branch wire 1220 connected to the same branch connector 1230 are electrically connected to the same display unit 1100. By providing a grounding terminal 1240 on the branch connector 1230, it is avoided to run an additional wire from the bus 1210 to ground the display unit 1100, which reduces the wiring density inside the display unit 1100 and reduces the risk of wire leakage and mutual interference. At the same time, by using the grounding terminal 1240 to electrically connect to the display unit 1100, the current can be directly introduced to the ground through the grounding terminal 1240 when the display unit 1100 leaks current. Since the display device 1000 is more susceptible to lightning strikes during thunderstorms, a grounding terminal 1240 can be installed on the branch connector 1230 to protect the display device 1000. It is easy to understand that the grounding terminal 1240 is made of a conductive material.

[0043] The bus 1210 also includes a first ground wire 1213. The grounding terminal 1240 is electrically connected to the first ground wire 1213 through a branch connector 1230 to ground the display unit 1100. The grounding terminal 1240 and the branch wire 1220 connected to the same branch connector 1230 are electrically connected to the same display unit 1100, making the power supply and leakage protection of each display unit 1100 independent, thereby improving the overall power supply stability and safety of the display device 1000.

[0044] Specifically, the grounding terminal 1240 can be a metal sheet, such as a copper sheet or an iron sheet. The grounding terminal 1240 can protrude from the branch connector 1230. One end of the grounding terminal 1240 is electrically connected to the first ground wire 1213 through the branch connector 1230, and the other end of the grounding terminal 1240 is electrically connected to the display unit 1100.

[0045] Optionally, the number of branch connectors 1230 is at least two, and at least two branch connectors 1230 are spaced apart on the bus 1210 along the extension direction of the bus 1210. By setting at least two branch connectors 1230 along the extension direction of the bus 1210, the branch wires 1220 connected to different branch connectors 1230 can be installed at different positions on the bus 1210, which facilitates the connection of each branch wire 1220 to different display units 1100 and avoids the branch wires 1220 from overlapping each other.

[0046] Each branch connector 1230 can be distributed within a different display unit 1100 to reduce the space occupied within a single display unit 1100.

[0047] Specifically, when there are two branch connectors 1230 and two display units 1100, the different branch connectors 1230 can be distributed in different display units 1100. When there are multiple branch connectors 1230 and multiple display units 1100, each branch connector 1230 can be distributed in a different display unit 1100.

[0048] In some other embodiments, multiple branch connectors 1230 may be distributed within the same display unit 1100. In this case, one of the branch wires 1220 connected to different branch connectors 1230 within the same display unit 1100 is electrically connected to the display unit 1100, while the other branch wires 1220 need to pass through the display unit 1100 and be electrically connected to the display unit 1100 that is being spliced ​​together.

[0049] Optionally, the number of branch connectors 1230 is equal to the number of branch wires 1220, and they are electrically connected in a one-to-one correspondence. The one-to-one electrical connection between branch connectors 1230 and branch wires 1220 is used to avoid a single branch connector 1230 connecting multiple branch wires 1220, which could lead to excessively dense wiring of local branch wires 1220 and leakage, thereby improving the power supply stability between the interconnected display units 1100.

[0050] Each branch connector 1230 is electrically connected to a different branch wire 1220, and each branch wire 1220 is electrically connected to a different display unit 1100. Specifically, among the interconnected display units 1100, a branch connector 1230 is distributed on the bus 1210 within the same display unit 1100, and a branch wire 1220 is electrically connected to the branch connector 1230. The branch wire 1220 is electrically connected to the display unit 1100 it belongs to.

[0051] Optionally, at least two branch wires 1220 are distributed on the same side of the bus 1210. Distributing the branch wires 1220 on the same side of the bus 1210 facilitates the production and processing of the transmission line 1200 and avoids increasing the processing flow of the transmission line 1200 when the branch wires 1220 are distributed on both sides of the bus 1210.

[0052] At least two branch wires 1220 distributed on the same side of the bus 1210 facilitate the connection of the power transmission line 1200 to different display units 1100 located on the same side of the power transmission line 1200. For example, the power transmission line 1200 can be provided on the same side of two interconnected display panels 1121 or on the same side of two interconnected display units 1100, and can be conveniently electrically connected to different display units 1100 through at least two branch wires 1220 on the same side of the bus 1210 of the power transmission line 1200.

[0053] Of course, in other embodiments, at least two branch wires 1220 are distributed on opposite sides of the bus 1210. In this case, the display units 1100 that are spliced ​​together on the same side of the bus 1210 can be electrically connected by increasing the length of the branch wires 1220; or, by rotating the angle of the branch wires 1220 relative to the axis of the bus 1210, each branch wire 1220 is located on the same side of the bus 1210.

[0054] Optionally, the display unit 1100 includes interconnected housing frames 1110 and display modules 1120. The housing frames 1110 of at least two display units 1100 are spliced ​​together to form the back frame 1101 of the display device 1000. The other end of each branch wire 1220 is electrically connected to the display module 1120 of a different display unit 1100. By splicing the housing frames 1110 of at least two display units 1100 together to form the back frame 1101 of the display device 1000, the manufacturing process of the back frame 1101 of the display device 1000, which is too large, is avoided when manufacturing a large-screen display device 1000, which would complicate the manufacturing process and increase costs. At the same time, the other end of each branch wire 1220 is electrically connected to the display module 1120 of a different display unit 1100, so that each display module 1120 is powered through different branch wires 1220, thereby improving the stability of power supply between the spliced ​​display units 1100.

[0055] To accommodate the large-screen display device 1000, the cabinet frame 1110 can be formed by splicing together a first sub-cabinet 1011 and a second sub-cabinet 1012. Specifically, the outer frame of the display unit 1100 may include two spliced ​​cabinet frames 1110, wherein each cabinet frame 1110 includes two spliced ​​first sub-cabinets 1011 and second sub-cabinets 1012. Of course, there can be multiple cabinet frames 1110.

[0056] Optionally, at least two display units 1100 are sequentially spliced ​​along a first direction. By sequentially splicing at least two display units 1100 along the first direction, a large-screen display of the display device 1000 is achieved. At the same time, splicing them together along the same direction also reduces the difficulty of the splicing process.

[0057] In this configuration, the bezels of adjacent display units 1100 that form an angle with the first direction and are close to each other are connected to achieve the splicing of display units 1100. At this time, the bus 1210 can pass through the bezel to provide power to different display units 1100. Specifically, the number of display units 1100 can be two, three, or more. When there are two display units 1100, the two display units 1100 are sequentially spliced ​​along the first direction to achieve a large-screen display effect.

[0058] Optionally, the bus 1210 of the power transmission line 1200 is located within the housing frame 1110. The housing frame 1110 includes a first side frame 1111 extending along a first direction. The bus 1210 is close to the first side frame 1111 and extends along the first direction. Placing the bus 1210 of the power transmission line 1200 within the housing frame 1110 avoids the bus 1210 occupying space outside the display device 1000, reducing the space occupied by the display device 1000. Simultaneously, the proximity of the bus 1210 to the first side frame 1111 and its extension along the first direction reduces mutual interference between the bus 1210 routing and electronic components within the housing frame 1110. It also prevents irregular routing of the bus 1210 within the housing frame 1110 from disrupting the continuous space within the housing frame 1110.

[0059] When at least two display units 1100 are sequentially spliced ​​along the first direction, the cabinet frames 1110 of at least two display units 1100 are also sequentially spliced ​​along the first direction. In each cabinet frame 1110, the bus 1210 is close to the first border 1111 and extends along the first direction, which makes the wiring of the bus 1210 in the display device 1000 more convenient. At the same time, it reduces the mutual interference between electronic devices and the bus 1210 in the display device 1000 and improves the power supply stability between the spliced ​​display units 1100.

[0060] Specifically, the display device 1000 may include two display units 1100 spliced ​​together along a first direction. The two spliced ​​display units 1100 correspond to two spliced ​​cabinet frames 1110. In each cabinet frame 1110, a bus 1210 extends close to the first border 1111 and along the first direction. The bus 1210 passes through one cabinet frame 1110 and enters the other cabinet frame 1110 along the first direction. Of course, the number of display units 1100 can be multiple, and the number of cabinet frames 1110 can also be multiple.

[0061] Optionally, along the first direction, the housing frame 1110 has two opposing second side frames 1112, and the second side frames 1112 have a first limiting groove 1001 extending along the first direction. The bus 1210 is installed in the first limiting groove 1001. The housing frame 1110 has a limiting part 1113, which is located between the two opposing second side frames 1112. The limiting part 1113 has a second limiting groove 1002 extending along the first direction, and the bus 1210 is also installed in the second limiting groove 1002. The first limiting groove 1001 and the second limiting groove 1002 are staggered along the first direction.

[0062] By installing the bus 1210 in the first limiting slot 1001 and the second limiting slot 1002, the bus 1210 is positioned to prevent its position from shifting within the housing frame 1110, thus affecting the power supply of the bus 1210 to the interconnected display units 1100. Furthermore, the first limiting slot 1001 and the second limiting slot 1002 are staggered along the first direction, causing the bus 1210 to bend when it enters the first limiting slot 1001 from the second limiting slot 1002. When the interconnected housing frames 1110 shift, the bent bus 1210 and the second frame 1112 interact to prevent the bus 1210 from changing its position. Moreover, due to the bending of the bus 1210, the bus 1210 has sufficient length to prevent the bus 1210 from being stretched or deformed due to the shift between the interconnected housing frames 1110.

[0063] In this embodiment, on the two interconnected box frames 1110, each of the two adjacent second sidewalls 1112 of the two box frames 1110 has a first limiting groove 1001. The first limiting grooves 1001 on the two second sidewalls 1112 are interconnected to allow the bus 1210 to pass through. Specifically, along the first direction, at least two limiting portions 1113 can be distributed at intervals between the two opposing second sidewalls 1112 of the same box frame 1110. By limiting the bus 1210 with at least two limiting portions 1113, the bus 1210 can be brought close to the first sidewall 1111 and extended along the first direction. In some embodiments, the bus 1210 is engaged with the first limiting groove 1001 on the second sidewall 1112 and the second limiting groove 1002 on the limiting portion 1113.

[0064] Optionally, the display module 1120 includes a display panel 1121 and a control board 1122. The control board 1122 is electrically connected to the display panel 1121. The other end of each branch wire 1220 is plugged into the control board 1122 of a different display unit 1100, so that the other end of each branch wire 1220 is electrically connected to the control board 1122 of a different display unit 1100. The control board 1122 is electrically connected to the display panel 1121 to control the display panel 1121 to perform the display. The other end of each branch wire 1220 is plugged into the control board 1122 of a different display unit 1100 to achieve a detachable connection between the branch wire 1220 and the display unit 1100. The plugging method facilitates the mutual electrical connection between the branch wire 1220 and the display unit 1100.

[0065] During the assembly of the display device 1000, the branch wires 1220 can be quickly installed into the control boards 1122 by connecting the other ends of each branch wire 1220 to the control boards 1122 of different display units 1100. Specifically, the connection between the branch wires 1220 and the display units 1100 can be achieved through plugs 1231 and sockets 1232.

[0066] Figure 5 This is a schematic diagram illustrating the connection between the power transmission line and the control board provided in an embodiment of this application. Figure 5 As shown, in some other embodiments, the control board 1122 includes a first control sub-board 1123 and a second control sub-board 1124, which are integrally formed. The first control sub-board 1123 is located in the first sub-box 1011, and the second control sub-board 1124 is located in the second sub-box 1012.

[0067] Optionally, each branch wire 1220 has a plug 1231 at the other end, and the display device 1000 includes a socket 1232. The socket 1232 is installed on the control board 1122 side of the control board 1122 opposite to the light emission direction of the display device 1000. The plug 1231 of each branch wire 1220 is plugged into the socket 1232 of a different display unit 1100. By providing a plug 1231 at the other end of the branch wire 1220 and a socket 1232 on the control board 1122, the branch wire 1220 and the display unit 1100 can be plugged into each other. At the same time, the socket 1232 is installed on the control board 1122 side of the control board 1122 opposite to the light emission direction of the display device 1000 to avoid the socket 1232 affecting the display panel 1121 on the light emission direction side of the display device 1000.

[0068] In this configuration, socket 1232 corresponds one-to-one with branch connector 1230. Socket 1232 is located on the side of control board 1122 near the first frame 1111 to reduce the length of branch wire 1220. Specifically, control board 1122 has multiple limiting openings, and socket 1232 has multiple corresponding limiting protrusions on the side near control board 1122. The limiting protrusions are embedded in the limiting openings to restrict the movement of socket 1232 and fix the position of socket 1232 on control board 1122.

[0069] Optionally, a conductive element 1300 is provided on the cabinet frame 1110, and the conductive element 1300 is electrically connected to the grounding terminal 1240 to ground the display unit 1100. By providing the conductive element 1300 on the cabinet frame 1110, the current on the cabinet frame 1110 is conducted to the ground using the conductive element 1300 and the grounding terminal 1240, avoiding leakage of the cabinet frame 1110 and improving the overall touch safety of the display device 1000.

[0070] The conductive element 1300 can be made of conductive metal. Specifically, the conductive element 1300 in the housing frame 1110 can be a conductive stud, which is mounted on the housing frame 1110, and the grounding terminal 1240 is electrically connected to the conductive stud. Of course, in some other embodiments, the conductive element 1300 can be a protruding conductive component on the housing frame 1110.

[0071] Optionally, the display device 1000 further includes an abutment 1400, which is connected to and clamps the grounding terminal 1240 via the conductive element 1300. The grounding terminal 1240 is clamped by the abutment 1400 and the conductive element 1300, thus fixing its position. Simultaneously, since the grounding terminal 1240 is mounted on the branch connector 1230, the position of the branch connector 1230 relative to the housing frame 1110 is also fixed. Because the branch wire 1220 is connected to the branch connector 1230, movement of the branch connector 1230 prevents loosening of the connection between the branch wire 1220 and the display unit 1100, thus avoiding unstable power supply between the interconnected display units 1100.

[0072] The conductive component 1300 has an opening for the insertion of the abutment component 1400, and the grounding terminal 1240 has a terminal opening. The abutment component 1400 includes an abutment portion and a connecting portion connected to each other. The connecting portion of the abutment component 1400 is inserted into the terminal opening and the opening in sequence, and the abutment portion is used to abut against the conductive terminal. Specifically, the conductive component 1300 can be a conductive stud with a screw hole, and the abutment component 1400 can be a conductive bolt that matches the conductive stud. The terminal opening allows the conductive bolt to be inserted, and the grounding terminal 1240 is electrically connected to one end of the conductive stud via a cylindrical surface.

[0073] Optionally, the number of branch wires 1220 is equal to the number of display units 1100, and they are electrically connected one-to-one. The branch wires 1220 and display units 1100 are connected one-to-one, so that each display unit 1100 is connected to a different branch wire 1220. Simultaneously, the power supply to each display unit 1100 is relatively independent, improving the stability of power supply between interconnected display units 1100. Furthermore, the problem of unstable power supply to display units 1100 in the display device 1000 is solved using a single transmission line 1200, saving costs.

[0074] The number of branch wires 1220 and the number of display units 1100 are at least two. Specifically, the number of branch wires 1220 and the number of display units 1100 can be two, three, or four, etc.
