Description

Technical Field

[0001] This application relates to the field of television technology, and more particularly to a television screen and a laser television. Background Technology

[0002] With the rapid development of laser display technology, laser TVs, due to their advantages of high brightness, wide color gamut, and ultra-short throw projection, are gradually becoming an important choice in the large-screen display market. The core components of a laser TV include a laser projector engine and a TV screen. The TV screen typically includes a multi-layered composite structure (such as Fresnel lens layers, anti-glare layers, and reflective layers) to achieve high contrast and resistance to ambient light interference.

[0003] In related technologies, the TV screen adopts a one-piece molding design. When the TV screen is large, such as exceeding 80 inches, it is very easy for the TV screen to be deformed due to vibration or squeezing during transportation. This will lead to problems such as distortion and dark corners in the projected image, increasing the difficulty of debugging laser TVs. Utility Model Content

[0004] This application discloses a television screen and a laser television, which can prevent the television screen from deforming during transportation, thereby reducing the difficulty of debugging the laser television.

[0005] To achieve the above objectives, this application discloses a television screen, comprising:

[0006] A first border, the first border extending along a first direction;

[0007] The second border is spaced apart from the first border in a second direction, the second border is parallel to the first border, and the second direction is perpendicular to the first direction;

[0008] A flexible screen body has a first side and a second side along the second direction. The portion of the flexible screen body near the first side is connected to the first frame, and the portion near the second side is connected to the second frame. Both the first side and the second side extend along the length direction of the flexible screen body, and the length direction of the flexible screen body is parallel to the first direction.

[0009] An elastic support member is detachably disposed between the first frame and the second frame, and the elastic support member enables the first frame and the second frame to maintain a preset gap.

[0010] In this embodiment, since the flexible screen body has a first side and a second side along the second direction, the portion of the flexible screen body near the first side is connected to the first frame, and the portion near the second side is connected to the second frame. An elastic support is detachably disposed between the first and second frames. The elastic support allows the first and second frames to maintain a preset gap. Therefore, during transportation, the flexible screen body, the first frame, the second frame, and the elastic support do not need to be assembled. Furthermore, the flexible screen body can be rolled up, thus preventing deformation of the large-sized TV screen during transportation and reducing transportation difficulty and cost. Upon arrival at its destination, the TV screen can be assembled. First, the portion of the flexible screen body near the first side is connected to the first frame, and the portion near the second side is connected to the second frame. Finally, the elastic support is detachably disposed between the first and second frames. This allows the flexible screen body to be tensioned, enabling the complete assembly of the TV screen. Therefore, this embodiment enables the transport and delivery of the TV screen in parts, reducing transportation difficulty and avoiding increased debugging difficulty due to deformation of the TV screen during transportation.

[0011] Similarly, when the TV screen is moved from one destination to another, the elastic support can be detached from the first and second frames. At this time, the deformable nature of the flexible screen body can be utilized to store the flexible screen body. The elastic support is then installed between the first and second frames at another destination to complete the assembly of the TV screen. It can be seen that this can prevent the TV screen from deforming during transportation or movement, and at the same time improve the convenience of moving the TV screen from one destination to another.

[0012] In addition, compared with the rigid fixation solution in related technologies, the combined solution of elastic pre-tightening and rigid fixing in this embodiment can, on the one hand, ensure the pre-tightening force of the flexible screen body, that is, moderate elastic support can improve the optical performance of the flexible screen body; on the other hand, it can save the labor costs of TV screen assembly and transportation.

[0013] In some possible implementations, a first insertion slot is provided on the first frame, and a second insertion slot is provided on the second frame;

[0014] The elastic support has a first end and a second end. The first end is inserted into the first insertion groove and abuts against the bottom of the first insertion groove. The second end is inserted into the second insertion groove and abuts against the bottom of the second insertion groove.

[0015] Since the first end is inserted into the first insertion slot and abuts against the bottom of the first insertion slot, and the second end is inserted into the second insertion slot and abuts against the bottom of the second insertion slot, on the one hand, the elastic support member can be detachably connected to the first frame and the second frame respectively by the first end cooperating with the first insertion slot and the second end cooperating with the second insertion slot. The structure is simple and easy to assemble.

[0016] On the other hand, compared with bolted connection structures, it can achieve "one-plug-in" connection, reducing installation time. Furthermore, because the first end abuts against the bottom of the first insertion slot and the second end abuts against the bottom of the second insertion slot, the force of the elastic support can be directly applied to the first and second frames along the second direction, improving the uniformity of stress distribution.

[0017] In some possible implementations, the elastic support includes a metal sheet whose length along the second direction is greater than the preset gap.

[0018] Therefore, during the TV screen assembly process, after the flexible screen body is connected to the first frame and the second frame respectively, the first end of the elastic support is first inserted into the first insertion slot, and then the metal sheet is bent so that the second end can be inserted into the second insertion slot. After the second end is inserted into the second insertion slot, the external force acting on the metal sheet is removed, and the metal sheet will be reset and deformed, so that the first end abuts against the bottom of the first insertion slot, and the second end abuts against the bottom of the second insertion slot, which can make the first frame and the second frame pull the flexible screen body together in a direction away from each other.

[0019] Because metal sheets have a simple structure, are easy to operate and assemble, and have good fatigue resistance, using metal sheets as elastic supports can simplify the assembly of television screens and improve their assembly structure, while also extending the lifespan of the television screen.

[0020] In some possible implementations, in the second direction, the sum of the depth of the first insertion slot, the depth of the second insertion slot, and the width of the preset gap is equal to the length of the metal sheet.

[0021] Therefore, when the metal sheet is detachably connected between the first frame and the second frame, and when the metal sheet is reset, the force provided to the first frame and the second frame to move away from each other can flatten the flexible screen body under the action of the preset pre-tightening force, thus ensuring the optical performance of the flexible screen body.

[0022] In some possible implementations, the elastic support includes a telescopic rod whose extension direction is parallel to the second direction.

[0023] Since the telescopic rod can extend and retract in the second direction, on the one hand, when assembling the elastic support, the length of the telescopic rod can be adjusted according to the preload force borne by the flexible screen body, which can reduce the assembly accuracy of the elastic support. On the other hand, by controlling the extension and retraction stroke of the telescopic rod, the telescopic rod can be made suitable for different TV screen specifications, thereby improving the applicability of the elastic support.

[0024] In addition, the telescopic rod can self-adaptively pre-tighten during installation, improving the installation and debugging efficiency of the elastic support components.

[0025] In some possible implementations, the telescopic rod includes:

[0026] The first rod extends in a direction parallel to the second direction, and a sliding groove is provided at the end of the first rod;

[0027] The second rod extends in a direction parallel to the second direction, and a portion of the second rod is movably inserted into the sliding groove;

[0028] An elastic element is disposed within the sliding groove and abuts against the end of the second rod extending into the sliding groove. The elastic element is capable of pushing the first rod and the second rod away from each other so that the first frame and the second frame maintain a preset gap.

[0029] Therefore, when assembling the telescopic rod, the end of the first rod is first inserted into the first insertion slot, then the second rod moves toward the first rod to compress and deform the elastic element, and finally the end of the second rod is inserted into the second insertion slot, and the elastic element is reset and deformed, so that the end of the first rod abuts against the bottom of the first insertion slot, and the end of the second rod abuts against the bottom of the second insertion slot, thereby making the flexible screen body tensioned and flattened.

[0030] As can be seen, the above structure enables visualized adjustment of the preload, and the double-bar structure has good torsional resistance, thus improving the structural reliability of the elastic support.

[0031] In some possible implementations, the elastic support includes a plurality of elastic support members, which are distributed at equal intervals along the first direction.

[0032] Since multiple elastic support members are distributed at equal intervals along the first direction, on the one hand, the area of ​​the elastic support members is increased in the first direction, thereby improving the support strength and stiffness of the elastic support members in the second direction. On the other hand, the equal interval distribution enables the first frame and the second frame to be subjected to a more uniform support force in the first direction, thereby improving the tension effect of the flexible screen body and thus improving the optical performance of the flexible screen body.

[0033] In addition, the evenly spaced distribution pattern is regular, making it easy to position and install during the installation process, thus improving the assembly efficiency of the elastic support components.

[0034] In some possible implementations, the first end and the second end are respectively provided with auxiliary connectors, the ends of the auxiliary connectors having convex arc surfaces, the first end being inserted into the first insertion slot through the auxiliary connectors, and the second end being inserted into the second insertion slot through the auxiliary connectors.

[0035] Since the first end is inserted into the first insertion slot through an auxiliary connector, and the second end is inserted into the second insertion slot through an auxiliary connector, and the end of the auxiliary connector has a convex arc surface, the convex arc surface has a guiding function, so as to guide the first end to enter the first insertion slot more easily when the first end is inserted into the first insertion slot, and guide the second end to enter the second insertion slot more easily when the second end is inserted into the second insertion slot, thereby reducing the insertion difficulty and improving the assembly efficiency. At the same time, it also avoids the first end and the second end from causing scratches or wear to the flexible screen body during the insertion process.

[0036] On the other hand, when the convex arc surface mates with the first or second insertion slot, it can adapt to the angular deviation between the connecting parts to a certain extent. Even if there is a slight inconsistency in the angle during installation, it can still complete the insertion well and maintain the stability of the connection.

[0037] In some possible implementations, the auxiliary connector includes a first shell and a second shell. The first shell is provided with a first snap-fit ​​structure, and the second shell is provided with a second snap-fit ​​structure. When the second snap-fit ​​structure engages with the first snap-fit ​​structure, the first end and the second end can be fixed inside the first shell or the second shell.

[0038] Therefore, the first snap-fit ​​structure and the second snap-fit ​​structure work together to form a reliable mechanical connection, which can effectively prevent the first end or the second end from falling out of the first shell and the second shell, and improve the stability of the connection between the first end and the second end and the auxiliary connector respectively.

[0039] Furthermore, when the second snap-fit ​​structure engages with the first snap-fit ​​structure, it guides the first and second shells, making them easy to align and connect. This simplifies and speeds up the installation process, improving the assembly efficiency of the auxiliary connectors at both ends. Moreover, disassembly is straightforward; simply release the snap-fit ​​in a specific manner without the need for complex tools, facilitating maintenance and repair.

[0040] Secondly, this application also provides a laser television, which includes the television screen described in the first aspect. This reduces the difficulty of debugging the laser television.

[0041] Compared with the prior art, the beneficial effects of this application are as follows:

[0042] In this embodiment, since the flexible screen body has a first side and a second side along the second direction, the portion of the flexible screen body near the first side is connected to the first frame, and the portion near the second side is connected to the second frame. An elastic support is detachably disposed between the first and second frames. The elastic support allows the first and second frames to maintain a preset gap. Therefore, during transportation, the flexible screen body, the first frame, the second frame, and the elastic support do not need to be assembled. Furthermore, the flexible screen body can be rolled up, thus preventing deformation of the large-sized TV screen during transportation and reducing transportation difficulty and cost. Upon arrival at its destination, the TV screen can be assembled. First, the portion of the flexible screen body near the first side is connected to the first frame, and the portion near the second side is connected to the second frame. Finally, the elastic support is detachably disposed between the first and second frames. This allows the flexible screen body to be tensioned, enabling the complete assembly of the TV screen. Therefore, this embodiment enables the transport and delivery of the TV screen in parts, reducing transportation difficulty and avoiding increased debugging difficulty due to deformation of the TV screen during transportation.

[0043] Similarly, when the TV screen is moved from one destination to another, the elastic support can be detached from the first and second frames. At this time, the deformable nature of the flexible screen body can be utilized to store the flexible screen body. The elastic support is then installed between the first and second frames at another destination to complete the assembly of the TV screen. It can be seen that this can prevent the TV screen from deforming during transportation or movement, and at the same time improve the convenience of moving the TV screen from one destination to another.

[0044] In addition, compared with the rigid fixation solution in related technologies, the combined solution of elastic pre-tightening and rigid fixing in this embodiment can, on the one hand, ensure the pre-tightening force of the flexible screen body, that is, moderate elastic support can improve the optical performance of the flexible screen body; on the other hand, it can save the labor costs of TV screen assembly and transportation.

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Unless otherwise stated, "a plurality of" means two or more.

[0069] As described in the relevant technology, the TV screen adopts a one-piece molding design. When the TV screen is large, such as exceeding 80 inches, it is very easy for the TV screen to be deformed due to vibration or squeezing during transportation. This will lead to problems such as distortion and dark corners in the projected image, increasing the difficulty of debugging the laser TV.

[0070] Based on this, the TV screen provided in this application can prevent the TV screen from deforming during transportation, thereby reducing the debugging difficulty of laser TV.

[0071] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0072] See Figure 1 , Figure 2 and Figure 3 This application provides a television screen 100, which includes a first frame 110, a second frame 120, a flexible screen body 130, and an elastic support member 140. The first frame 110 extends along a first direction; the second frame 120 is spaced apart from the first frame 110 in a second direction, and the second frame 120 is parallel to the first frame 110, with the second direction perpendicular to the first direction; the flexible screen body 130 has a first side 131 and a second side 132 along the second direction, with the portion of the flexible screen body 130 near the first side 131 connected to the first frame 110 and the portion near the second side 132 connected to the second frame 120, both the first side 131 and the second side 132 extending along the length direction of the flexible screen body 130, which is parallel to the first direction; the elastic support member 140 is detachably disposed between the first frame 110 and the second frame 120, and the elastic support member 140 enables the first frame 110 and the second frame 120 to maintain a preset gap.

[0073] The first direction mentioned above refers to the direction parallel to the length direction of the flexible screen body 130, that is... Figure 2 The direction indicated by the X-arrow, the second direction, refers to the direction parallel to the width direction of the flexible screen body 130, that is... Figure 2 The direction indicated by the Y-arrow in the middle.

[0074] The aforementioned elastic support 140 enables the first frame 110 and the second frame 120 to maintain a preset gap. It should be understood that since the specifications of the flexible screen body 130 are fixed, that is, its length and width are fixed, in order for the elastic support 140 to support the flexible screen body 130 flat, the first frame 110 and the second frame 120 need to straighten the flexible screen body 130 along the width direction of the flexible screen. Therefore, the size of the preset gap is affected by the width of the flexible screen body 130.

[0075] The aforementioned flexible screen body 130 includes, but is not limited to, Fresnel flexible screens, black grid flexible screens, etc.

[0076] The first frame 110 and the second frame 120 mentioned above play a positioning and supporting role for the flexible screen body 130. The materials of the first frame 110 and the second frame 120 can be metal materials such as aluminum and stainless steel, or non-metal materials such as hard plastic. The shape of the first frame 110 and the second frame 120 is not specifically limited.

[0077] For example, the first frame 110 and the second frame 120 include a fixed part and a connecting part that are connected to each other, wherein the connecting part is connected to the elastic support 140 and the fixed part is connected to the flexible screen body 130. The fixed part is hollow, taking into account the overall weight of the TV screen 100.

[0078] The portion of the flexible screen body 130 near the first side 131 is connected to the first frame 110, and the portion near the second side 132 is connected to the second frame 120. It should be understood that there are various ways in which the flexible screen body 130 is connected to the first frame 110 and the second frame 120 respectively. For example, the flexible screen body 130 is bonded and fixed to the first frame 110 and the second frame 120 respectively by double-sided adhesive, or the flexible screen body 130 is bonded and fixed to the first frame 110 and the second frame 120 respectively by dotted adhesive.

[0079] There are various structures in which the elastic support member 140 is detachably disposed between the first frame 110 and the second frame 120. For example, the elastic support member 140 is detachably disposed between the first frame 110 and the second frame 120 by means of a snap-fit ​​structure, or the elastic support member 140 is detachably disposed between the first frame 110 and the second frame 120 by means of screws or pins, etc.

[0080] In this embodiment, since the flexible screen body 130 has a first side 131 and a second side 132 along the second direction, the portion of the flexible screen body 130 near the first side 131 is connected to the first frame 110, and the portion near the second side 132 is connected to the second frame 120. Furthermore, the elastic support member 140 is detachably disposed between the first frame 110 and the second frame 120. The elastic support member 140 allows the first frame 110 and the second frame 120 to maintain a preset gap. Therefore, during transportation, the television screen 100 does not require assembly of the flexible screen body 130, the first frame 110, the second frame 120, and the elastic support member 140. Additionally, the flexible screen body 130 can be rolled up, thus avoiding the need for excessively large dimensions. The large TV screen 100 can deform during transportation, which reduces transportation difficulty and cost. After the TV screen 100 arrives at its destination, it can be assembled. First, the part of the flexible screen body 130 near the first side 131 is connected to the first frame 110, and the part near the second side 132 is connected to the second frame 120. Finally, the elastic support 140 is detachably set between the first frame 110 and the second frame 120. In this way, the flexible screen body 130 can be tensioned, and the complete TV screen 100 can be assembled. It can be seen that this embodiment can realize the disassembled transportation and delivery of the TV screen 100, reducing transportation difficulty, and avoiding the increase in debugging difficulty of the laser TV due to the deformation of the TV screen 100 during transportation.

[0081] Similarly, when the TV screen 100 is moved from one destination to another, the elastic support 140 can be detached from the first frame 110 and the second frame 120. At this time, the deformable nature of the flexible screen body 130 can be used to store the flexible screen body 130. The elastic support 140 can be installed between the first frame 110 and the second frame 120 at another destination to complete the assembly of the TV screen 100. It can be seen that the deformation of the TV screen 100 during transportation or movement can be avoided, and the convenience of moving the TV screen 100 from one destination to another can be improved.

[0082] In addition, compared with the rigid fixation solution of the related art, the combined solution of elastic pre-tightening and rigid fixing in this embodiment can, on the one hand, ensure the pre-tightening force of the flexible screen body 130, that is, the appropriate elastic support can improve the optical performance of the flexible screen body 130. On the other hand, it can save the labor cost of assembling and transporting the TV screen 100.

[0083] In some possible embodiments, see Figure 3 and Figure 4The first frame 110 is provided with a first insertion groove 111, and the second frame 120 is provided with a second insertion groove 121; the elastic support member 140 has a first end 141 and a second end 142, the first end 141 is inserted into the first insertion groove 111 and abuts against the bottom of the first insertion groove 111, and the second end 142 is inserted into the second insertion groove 121 and abuts against the bottom of the second insertion groove 121.

[0084] It should be noted that the shape and size of the first insertion slot 111 are adapted to the shape and size of the first end 141. That is, when the shape of the first end 141 is a cuboid, the internal space of the first insertion slot 111 is also a cuboid. The thickness and width of the first insertion slot 111 are slightly larger or approximately equal to the thickness and width of the first end 141. This facilitates the insertion of the first end 141 into the first insertion slot 111 while preventing the first end 141 from wobbling relative to the first insertion slot 111, thus ensuring the reliability of the assembly of the first end 141 relative to the first insertion slot 111. Similarly, the shape and size of the second insertion slot 121 are adapted to the shape and size of the second end 142.

[0085] Since the first end 141 is inserted into the first insertion slot 111 and abuts against the bottom of the first insertion slot 111, and the second end 142 is inserted into the second insertion slot 121 and abuts against the bottom of the second insertion slot 121, on the one hand, the elastic support member 140 is detachably connected to the first frame 110 and the second frame 120 respectively by the cooperation of the first end 141 with the first insertion slot 111 and the second end 142 with the second insertion slot 121. The structure is simple and easy to assemble.

[0086] On the other hand, compared with bolted connection structures, it can achieve "one-plug-in" connection, reducing installation time. Furthermore, since the first end 141 abuts against the bottom of the first insertion groove 111 and the second end 142 abuts against the bottom of the second insertion groove 121, the force of the elastic support 140 can be directly applied to the first frame 110 and the second frame 120 along the second direction, improving the uniformity of stress distribution.

[0087] In some possible embodiments, see Figure 4 The elastic support 140 includes a metal sheet, the length of which is greater than a preset gap.

[0088] Therefore, during the assembly of the TV screen 100, after the flexible screen body 130 is connected to the first frame 110 and the second frame 120 respectively, the first end 141 of the elastic support member 140 is first inserted into the first insertion slot 111, and then the metal sheet is bent so that the second end 142 can be inserted into the second insertion slot 121. After the second end 142 is inserted into the second insertion slot 121, the external force acting on the metal sheet is removed, and the metal sheet will be reset and deformed, so that the first end 141 abuts against the bottom of the first insertion slot 111 and the second end 142 abuts against the bottom of the second insertion slot 121, which can make the first frame 110 and the second frame 120 pull the flexible screen body 130 together in a direction away from each other.

[0089] Because metal sheets have a simple structure, are easy to operate and assemble, and have good fatigue resistance, when the elastic support 140 is a metal sheet, it can simplify the assembly operation and assembly structure of the TV screen 100, and at the same time help to improve the service life of the TV screen 100.

[0090] In addition, the aforementioned metal sheet can be made of steel, iron, copper, etc., and the metal sheet is in the shape of a strip.

[0091] In some possible embodiments, see Figure 4 In the second direction, the sum of the depth of the first insertion slot 111 (the distance represented by d1 in the figure), the depth of the second insertion slot 121 (the distance represented by d2 in the figure), and the width of the preset gap (the distance represented by d3 in the figure) is equal to the length of the metal sheet.

[0092] It should be noted that, in the second direction, the sum of the depth of the first insertion groove 111, the depth of the second insertion groove 121, and the width of the preset gap is equal to the length of the metal sheet. It should be understood that the length of the metal sheet is slightly greater than or equal to the sum of the depth of the first insertion groove 111, the depth of the second insertion groove 121, and the width of the preset gap.

[0093] Therefore, when the metal sheet is detachably connected between the first frame 110 and the second frame 120, and when the metal sheet is reset, the force provided to the first frame 110 and the second frame 120 to move away from each other can make the flexible screen body 130 flattened under the action of the preset pre-tightening force, thus ensuring the optical performance of the flexible screen body 130.

[0094] In some possible embodiments, see Figure 5 The elastic support 140 includes a telescopic rod 143, the telescopic direction of which is parallel to the second direction.

[0095] Since the telescopic rod 143 can extend and retract in the second direction, on the one hand, when assembling the elastic support 140, the length of the telescopic rod 143 can be adjusted according to the preload force borne by the flexible screen body 130, thereby reducing the assembly accuracy of the elastic support 140. On the other hand, by controlling the extension and retraction stroke of the telescopic rod 143, the telescopic rod 143 can be adapted to the specifications of different TV screens 100, thereby improving the applicability of the elastic support 140.

[0096] In addition, the telescopic rod 143 can also self-adaptively pre-tighten during installation, which improves the installation and debugging efficiency of the elastic support 140.

[0097] In addition, the structure of the telescopic rod 143 includes various types, such as the sleeve-type telescopic rod 143, the pneumatic telescopic rod 143, and the electric push rod. The following mainly uses the sleeve-type telescopic rod 143 as an example for detailed explanation.

[0098] In some possible embodiments, see Figure 5 and Figure 6 The telescopic rod 143 includes a first rod 1431, a second rod 1432, and an elastic member 1433. The extension direction of the first rod 1431 is parallel to the second direction, and the end of the first rod 1431 is provided with a sliding groove 14311. The extension direction of the second rod 1432 is parallel to the second direction, and a portion of the second rod 1432 is movably inserted into the sliding groove 14311. The elastic member 1433 is disposed in the sliding groove 14311 and abuts against the end of the second rod 1432 that extends into the sliding groove 14311. The elastic member 1433 can provide a pushing force to move the first rod 1431 and the second rod 1432 away from each other so that the first frame 110 and the second frame 120 maintain a preset gap.

[0099] The specific shapes of the first rod 1431 and the second rod 1432 are not limited. For example, both the first rod 1431 and the second rod 1432 can be cylindrical or quadrangular prisms.

[0100] Therefore, when assembling the telescopic rod 143, the end of the first rod 1431 is first inserted into the first insertion slot 111, then the second rod 1432 moves toward the first rod 1431 to compress and deform the elastic element 1433, and finally the end of the second rod 1432 is inserted into the second insertion slot 121, and the elastic element 1433 is reset and deformed, so that the end of the first rod 1431 abuts against the bottom of the first insertion slot 111, and the end of the second rod 1432 abuts against the bottom of the second insertion slot 121, thereby making the flexible screen body 130 tensioned and flattened.

[0101] As can be seen, the above structure enables visual adjustment of the preload, and the double-bar structure has good torsional resistance, thus improving the structural reliability of the elastic support 140.

[0102] Optional, see Figure 7 A limiting groove 14312 is provided on the groove wall of the sliding groove 14311 of the first rod 1431. The extending direction of the limiting groove 14312 is the same as the extending direction of the first rod 1431. A limiting post 14321 is provided on the outer peripheral wall of the second rod 1432. The limiting post 14321 is slidably inserted into the limiting groove 14312. In this way, on the one hand, the range of movement of the second rod 1432 relative to the first rod 1431 can be limited, and on the other hand, the second rod 1432 can be prevented from detaching from the first rod 1431.

[0103] In some possible embodiments, see Figure 2 The elastic support member 140 includes multiple members, and the multiple elastic support members 140 are distributed at equal intervals along the first direction.

[0104] The aforementioned multiple elastic support members 140 refer to two or more elastic support members 140.

[0105] Since multiple elastic support members 140 are evenly distributed along the first direction, on the one hand, the area of ​​the elastic support members 140 is increased in the first direction, thereby improving the support strength and stiffness of the elastic support members 140 in the second direction. On the other hand, the evenly distributed distribution enables the first frame 110 and the second frame 120 to be subjected to a more uniform support force in the first direction, thereby improving the tension effect of the flexible screen body 130 and thus improving the optical performance of the flexible screen body 130.

[0106] In addition, the evenly spaced distribution pattern is regular, making it easy to position and install during the installation process, thus improving the assembly efficiency of the elastic support component 140.

[0107] In some possible embodiments, see Figure 8 The first end 141 and the second end 142 are respectively provided with auxiliary connectors 150. The end of the auxiliary connector 150 has a convex arc surface 150a. The first end 141 is inserted into the first insertion slot 111 through the auxiliary connector 150, and the second end 142 is inserted into the second insertion slot 121 through the auxiliary connector 150.

[0108] Since the first end 141 is inserted into the first insertion slot 111 through the auxiliary connector 150, and the second end 142 is inserted into the second insertion slot 121 through the auxiliary connector 150, and the end of the auxiliary connector 150 has a convex arc surface 150a, the convex arc surface 150a has a guiding function, so as to guide the first end 141 to enter the first insertion slot 111 more easily when the first end 141 is inserted into the first insertion slot 111, and guide the second end 142 to enter the second insertion slot 121 more easily when the second end 142 is inserted into the second insertion slot 121, thereby reducing the insertion difficulty, improving the assembly efficiency, and also avoiding the situation where the first end 141 and the second end 142 cause scratches or wear to the flexible screen body 130 during the insertion process.

[0109] On the other hand, when the convex arc surface 150a mates with the first insertion groove 111 or the second insertion groove 121, it can adapt to the angular deviation between the connecting parts to a certain extent. Even if there is a slight angular inconsistency during the installation process, it can still complete the insertion well and maintain the stability of the connection.

[0110] In addition, the aforementioned convex arc surface 150a can be a semi-circular arc surface, a semi-elliptical arc surface, a parabolic arc surface, etc.

[0111] In some possible embodiments, see Figure 8 , Figure 9 and Figure 10 The auxiliary connector 150 includes a first shell 151 and a second shell 152. A first snap-fit ​​structure 1511 is provided inside the first shell 151, and a second snap-fit ​​structure 1521 is provided inside the second shell 152. When the second snap-fit ​​structure 1521 engages with the first snap-fit ​​structure 1511, the first end 141 or the second end 142 can be fixed inside the first shell 151 and the second shell 152.

[0112] Thus, the first snap-fit ​​structure 1511 and the second snap-fit ​​structure 1521 engage to form a reliable mechanical connection, which can effectively prevent the first end 141 or the second end 142 from falling out of the first shell 151 and the second shell 152, thereby improving the stability of the connection between the first end 141 and the second end 142 and the auxiliary connector 150, respectively.

[0113] Furthermore, when the second snap-fit ​​structure 1521 engages with the first snap-fit ​​structure 1511, it guides the first shell 151 and the second shell 152, making them easy to align and connect. This simplifies and speeds up the installation process, thereby improving the assembly efficiency of the auxiliary connector 150 located at the first end 141 and the second end 142. Moreover, disassembly only requires releasing the snap-fit ​​in a specific manner, eliminating the need for complex tools and facilitating maintenance and repair.

[0114] Optional, see Figure 9 and Figure 10 The first shell 151 is provided with a first protrusion, and the second shell 152 is provided with a second protrusion. The first snap-fit ​​structure 1511 is a snap-fit ​​groove provided on the first protrusion, and the second snap-fit ​​structure 1521 is a snap-fit ​​protrusion provided on the second protrusion.

[0115] Optional, see Figure 9 and Figure 10 The first snap-fit ​​structure 1511 is a snap hook provided on the edge of the first shell 151, and the second snap-fit ​​structure 1521 is a protrusion provided on the edge of the second shell 152. When the snap hook and the protrusion are engaged, the first shell 151 and the second shell 152 can be fastened together.

[0116] Of course, in some other embodiments, the connection structure between the auxiliary connector 150 and the first end 141 includes, but is not limited to, the auxiliary connector 150 being integrally formed with the first end 141, the auxiliary connector 150 being welded to the first end 141, etc., and the connection structure between the auxiliary connector 150 and the second end 142 is the same as the connection structure between the auxiliary connector 150 and the first end 141.

[0117] Alternatively, see Figure 11 A receiving groove 112 is provided on the surface of both the first frame 110 and the second frame 120. The portion of the flexible screen body 130 near the first side 131 is located in the receiving groove 112 of the first frame 110, and the portion of the flexible screen body 130 near the second side 132 is located in the receiving groove 112 of the second frame 120. The surface of the flexible screen body 130 protrudes from the surfaces of the first frame 110 and the second frame 120. Thus, the receiving groove 112 can limit the flexible screen body 130 when it is connected to the first frame 110 and the second frame 120. Since the surface of the flexible screen body 130 protrudes from the surfaces of the first frame 110 and the second frame 120, it is easy to apply pressure when the flexible screen body 130 is connected to the first frame 110 and the second frame 120, thereby improving the firmness of the connection between the flexible screen body 130 and the first frame 110 and the second frame 120.

[0118] This application also provides a laser TV, which includes a TV screen 100.

[0119] The television screen 100 is the same as the television screen 100 in the above embodiments. Its structure and function are the same as those of the television screen 100 in the above embodiments. Please refer to the description in the above embodiments. It will not be repeated here.

[0120] Since laser TVs include the TV screen 100 in the above embodiments, the debugging difficulty of laser TVs can be reduced and the user experience can be improved.

[0121] Optionally, the laser TV also includes a light source assembly, a light processing system, and a projection system. The light source assembly provides a high-brightness, high-purity three-color laser light source. The light processing system converts electrical signals into light signals and processes the grayscale and color of the image. For example, a digital micromirror device has millions of rotatable micromirrors (each micromirror corresponds to a pixel) on its surface. By controlling the rotation angle of the micromirrors (usually ±12°), different proportions of laser light are reflected to the projection system or absorbed (forming a dark state), thereby achieving pixel brightness adjustment. The transmission system amplifies the image beam output by the light processing system and transmits it onto the TV screen 100.

[0122] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
