Technical Field

[0001] This disclosure relates to the field of display devices, and particularly to a display device. Background Technology

[0002] Flexible display panels are increasingly being used in various display devices, enabling these devices to fold, roll, and change their display area.

[0003] For example, in a rollable display device, the flexible display panel is wound around a spool. The display area varies depending on the length of the flexible display panel pulled out relative to the spool, thus allowing the display area to be adjusted as needed. However, in this type of display device, the flexible display panel needs to be wound into a spiral shape, and one end of the flexible display panel needs to be fixed inside the spool, making the overall structure of the display device relatively complex. Summary of the Invention

[0018] Optionally, the display device further includes a recycling plate located on the second side of the second housing and connected to the edge of the flexible display panel;

[0019] All of the tensioning strips are connected to the recycling plate.

[0020] Optionally, the display device further includes a baffle located on a second side of the second housing and connected to the second housing, wherein the flexible display panel is located on the side of the baffle closer to the second housing;

[0021] The recycling plate is provided with a rolling element, which rolls in cooperation with the baffle.

[0022] Optionally, the display device further includes a plurality of guide rails and a plurality of sliders. The plurality of guide rails are located in the first housing and connected to the first housing.

[0030] By connecting one end of the flexible display panel to the first housing, the flexible display panel wraps around from the first surface of the second housing to the second surface, and then connects to a tension strip. The tension strip extends to the first surface of the second housing and is fixed to the first housing. When the second housing extends relative to the first housing, the support portion of the second housing pushes the flexible display panel outward, causing a larger portion of the flexible display panel to move to the first surface of the second housing. The flexible display panel remains flat under the action of the tension strip, enabling normal display. When the second housing retracts relative to the first housing, the push rod of the second housing pushes the tension strip through a pulley, causing the tension strip to pull the flexible display panel inward, causing a portion of the flexible display panel to move from the first surface of the second housing to the second surface. The flexible display panel remains flat under the action of the tension strip, enabling normal display. By adjusting the first and second housings, the area of ​​the flexible display panel located on the first surface of the second housing can be changed, thereby changing the display area. The structure is simple. Attached Figure Description

[0048] Figure 1 This is a schematic diagram of a display device provided in an embodiment of this disclosure. The display device may be, but is not limited to, a mobile phone or a tablet computer. This embodiment uses a mobile phone as an example for illustration. Figure 1 As shown, the display device includes a first housing 10, a second housing 20, a flexible display panel 30, and a tension bar 40.

[0049] Figure 2 This is an assembly diagram of the first housing and the second housing provided in an embodiment of this disclosure. Figure 2 As shown, the first housing 10 has an opening 10a on one side, and the second housing 20 is partially housed in the opening 10a. The second housing 20 is telescopic relative to the first housing 10. By adjusting the second housing 20 relative to the first housing 10, the display area of ​​the flexible display panel 30 can be changed.

[0050] like Figure 2 As shown, the second housing 20 includes a support 21, a push rod 22 and a pulley 23. One end of the push rod 22 is connected to the support 21, and the pulley 23 is located at the other end of the push rod 22.

[0051] Figure 3 and Figure 4 This is a schematic diagram of the structure of a display device provided in an embodiment of this disclosure. Figure 3 and Figure 4 The display device's internal structure has been partially removed to show its overall structure. Among these, Figure 3 and Figure 4 The two states of the display device are shown respectively. For example... Figure 3 and Figure 4As shown, the first end of the flexible display panel 30 is located on the first surface of the second housing 20. The second surface of the second housing 20 is opposite to the first surface. The second housing 20 has opposite first and second surfaces; when the user views the display screen, the first surface of the second housing 20 faces the user, and the second surface faces away from the user. The flexible display panel 30 is rectangular in its flattened state, and the first and second ends of the flexible display panel 30 are its two ends along its length in the flattened state.

[0052] The first end of the flexible display panel 30 is located on one side of the first housing 10 and is connected to the first housing 10. The second end of the flexible display panel 30 bypasses the support portion 21 and extends to the second surface of the second housing 20.

[0053] Tensioner 40 is located in the first housing 10. One end of tensioner 40 is located on the second surface of the second housing 20 and is connected to the flexible display panel 30. The other end of tensioner 40 passes around pulley 23, extends to the first surface of the second housing 20, and is connected to the first housing 10. For example, tensioner 40 is connected to the first housing 10 by screws.

[0054] By connecting one end of the flexible display panel 30 to the first housing 10, the flexible display panel 30 wraps around from the first surface of the second housing 20 to the second surface, and then connects to the tension bar 40. The tension bar 40 extends to the first surface of the second housing 20 and is fixed to the first housing 10. When the second housing 20 extends relative to the first housing 10, the support portion 21 of the second housing 20 pushes the flexible display panel 30 outward, causing a larger portion of the flexible display panel 30 to move to the first surface of the second housing 20. The flexible display panel 30 remains flat under the action of the tension bar 40, enabling normal display. When the second housing 20 retracts relative to the first housing 10, the push rod 22 of the second housing 20 pushes the tension bar 40 through the pulley 23, causing the tension bar 40 to pull the flexible display panel 30 inward, causing a portion of the flexible display panel 30 to move from the first surface of the second housing 20 to the second surface. The flexible display panel 30 remains flat under the action of the tension bar 40, enabling normal display. By adjusting the first housing 10 and the second housing 20, the area of ​​the flexible display panel 30 located on the first surface of the second housing 20 can be changed, thereby changing the display area. The structure is simple.

[0055] Figure 5 This is a schematic diagram of the structure of a first housing provided in an embodiment of this disclosure. Figure 5As shown, the first housing 10 includes a top plate 11, a back plate 12, and a plurality of side plates 13. The top plate 11 and the back plate 12 are opposite to each other, and the plurality of side plates 13 are connected between the top plate 11 and the back plate 12. The top plate 11, the back plate 12, and the plurality of side plates 13 form a box-shaped structure with an opening 10a on one side to partially accommodate the first housing 10. One end of the flexible display panel 30 is located outside the first housing 10, that is, outside the space enclosed by the top plate 11, the back plate 12, and the plurality of side plates 13, specifically on the side of the top plate 11 away from the back plate 12.

[0056] The first housing 10 can be a one-piece structure or a detachable structure. For example, the back panel 12 and the side panel 13 can be detachably connected to facilitate the assembly and disassembly of the display device.

[0057] Figure 6 This is a schematic diagram of the structure of a second housing provided in an embodiment of this disclosure. Figure 6 As shown, the second housing 20 includes a support 21, a sliding plate 24, a push rod 22, and a pulley 23.

[0058] Figure 7 This is an exploded structural diagram of a second housing provided in an embodiment of this disclosure. For example... Figure 7 As shown, the support part 21 includes a roller 212 and a roller bracket 211. The roller 212 and the push rod 22 are located on opposite sides of the roller bracket 211 and are respectively connected to the roller bracket 211.

[0059] The roller 212 is rotatably connected to the roller support 211, and the roller 212 can rotate relative to the roller support 211. The flexible display panel 30 is wound from the first side to the second side of the second housing 20 via the roller 212, so that when the flexible display panel 30 moves relative to the second housing 20, the resistance is smaller and the movement is smoother.

[0060] Optionally, the second housing 20 includes a plurality of push rods 22 and a plurality of pulleys 23 in a one-to-one correspondence, with the push rods 22 arranged in parallel at intervals. For example, in this example, the second housing 20 includes two push rods 22 and two pulleys 23, with the two push rods 22 arranged in parallel at intervals along the length direction of the roller 212, and each push rod 22 having a pulley 23 at the end away from the roller support 211.

[0061] The display device includes multiple tension bars 40, which are arranged in a one-to-one correspondence with multiple pulleys 23, and the multiple tension bars 40 pass around the corresponding pulleys 23.

[0062] By setting multiple push rods 22 and multiple tension bars 40, the multiple tension bars 40 apply force to different positions of the flexible display panel 30, enabling the flexible display panel 30 to move more smoothly and be flatter.

[0063] Optionally, the tension strip 40 can be a flexible component, such as a strip structure made of materials like polyethylene terephthalate, polyimide, or stainless steel. This allows for easy bending and smooth movement around the pulley 23 during the relative movement of the first housing 10 and the second housing 20, preventing excessive stretching and stress on the flexible display panel 30, which could lead to damage. Furthermore, tension strips 40 made of these materials exhibit minimal deformation along their length, preventing jerks and discontinuities during movement.

[0064] Optionally, the push rod 22 has a strip groove 22a extending along its length. The pulley 23 is located in the strip groove 22a.

[0065] By providing the slot 22a, the shaft of the pulley 23 can be connected to the side wall of the slot 22a when installing the pulley 23, which facilitates the installation of the pulley 23. Furthermore, by installing the pulley 23 in the slot 22a, the slot 22a provides protection for the pulley 23, preventing other internal structures of the display device from contacting the pulley 23 and affecting its normal rotation.

[0066] Furthermore, since the pulley 23 is in the strip groove 22a, the tension bar 40 needs to pass through the strip groove 22a when it goes around the pulley 23. The strip groove 22a can limit the tension bar 40, preventing the tension bar 40 from coming off the pulley 23 and improving the reliability of the display device.

[0067] Optionally, pulley 23 can be a rubber wheel. The rubber wheel has a certain degree of elasticity and can deform to some extent when in contact with the tension bar 40, thereby providing a larger contact area between the tension bar 40 and pulley 23. The rubber wheel has a high coefficient of friction, generating significant friction between it and the tension bar 40, thus preventing slippage between the tension bar 40 and pulley 23.

[0068] In other examples, pulley 23 may also be a metal wheel or a plastic wheel. A bearing may also be provided at the axle of pulley 23 to reduce rotational friction.

[0069] like Figure 7 As shown, the sliding plate 24 and the push rod 22 are located on the same side of the roller bracket 211. The sliding plate 24 is connected to the roller bracket 211. (Refer to...) Figure 2 As shown, the sliding plate 24 is slidably connected to the first housing 10.

[0070] The sliding plate 24 engages with the first housing 10, enabling the second housing 20 to move smoothly relative to the first housing 10.

[0071] like Figure 7 As shown, the sliding plate 24 is comb-shaped. (Refer to...) Figure 5As shown, the outer surface of the top plate 11 of the first housing 10 has a plurality of sliding grooves 11a. The sliding grooves 11a extend from the side of the top plate 11 near the opening 10a to the other side. The sliding plate 24 is inserted into the plurality of sliding grooves 11a and forms a cooperation with the sliding grooves 11a, thereby being able to slide along the sliding grooves 11a.

[0072] Optionally, the thickness of the sliding plate 24 is the same as the depth of the groove 11a, which makes the surface of the sliding plate 24 close to the flexible display panel 30 and the outer surface of the top plate 11 flush, so as to provide support for the flexible display panel 30 and keep the flexible display panel 30 flat.

[0073] like Figure 7 As shown, a plurality of magnetic sheets 241 are disposed on the surface of the sliding plate 24 near the flexible display panel 30.

[0074] The sliding plate 24 is located outside the top plate 11 of the first housing 10. A magnetic sheet 241 is disposed on the surface of the sliding plate 24 away from the top plate 11, close to the back of the flexible display panel 30. The magnetic sheet 241 is used to attract the flexible display panel 30, preventing it from arching due to its own elasticity and making it flatter. The front of the flexible display panel 30 is the side used for display, and the back is the side opposite to the front.

[0075] like Figure 7 As shown, the surface of the sliding plate 24 has a mounting groove 24a, in which a magnetic sheet 241 is disposed. Exemplarily, the mounting groove 24a extends from the side of the sliding plate 24 away from the roller bracket 211 to the side closer to the roller bracket 211, so as to facilitate sliding the magnetic sheet 241 into the mounting groove 24a.

[0076] In other examples, the magnetic sheet 241 can also be mounted on the surface of the sliding plate 24 by means of adhesive or other methods.

[0077] like Figure 7 As shown, the support portion 21 also includes a plurality of magnetic rings 213. The plurality of magnetic rings 213 are sleeved on the outside of the roller 212.

[0078] The magnetic ring 213 not only supports the flexible display panel 30, allowing it to move smoothly relative to the second housing 20, but also, like the magnetic sheet 241, can attract the flexible display panel 30, preventing it from arching.

[0079] In order for the flexible display panel 30 to be attracted by the magnetic sheet 241, a corresponding ferromagnetic structure is provided on the back of the flexible display panel 30, as detailed in the following description.

[0080] Figure 8This is a partial structural schematic diagram of a display device provided in an embodiment of this disclosure. For example... Figure 8 As shown, a flexible support plate 31 is provided on the side of the flexible display panel 30 near the magnetic ring 213, and the flexible support plate 31 is ferromagnetic.

[0081] The flexible support plate 31 serves to support the flexible display panel 30. The flexible support plate 31 is ferromagnetic, so it can be attracted by the magnetic sheet 241 and the magnetic ring 213, keeping the flexible support plate 31 flat, which in turn keeps the flexible display panel 30 flat.

[0082] For example, the flexible support plate 31 is bonded to the flexible display panel 30 so that the flexible display panel 30 can bend along with the flexible support plate 31.

[0083] Figure 9 This is a schematic diagram of the structure of a flexible support plate provided in an embodiment of this disclosure. Figure 9 As shown, the flexible support plate 31 includes a first support plate 311, a second support plate 312, and a connecting plate 313. The first support plate 311 and the connecting plate 313 are located on opposite sides of the second support plate 312. The first support plate 311 is connected to the outer wall of the first housing 10. The second support plate 312 has a plurality of strip holes 312a distributed thereon. The second support plate 312 extends from the first surface to the second surface of the second housing 20. The connecting plate 313 is connected to the tensioning strip 40.

[0084] During the relative movement of the first housing 10 and the second housing 20, a portion of the flexible display panel 30 remains outside the top plate 11 of the first housing 10, and this portion of the flexible display panel 30 will not bend. This portion of the flexible display panel 30 is supported by the first support plate 311, keeping it flat. The second support plate 312 has multiple strip-shaped holes 312a, which allows it to bend while maintaining a certain structural strength. Multiple tension bars 40 are connected to the connecting plate 313, preventing uneven stress on the second support plate 312 and thus avoiding torsional deformation, allowing the flexible support plate 312 to move smoothly under the traction of the tension bars 40.

[0085] like Figure 9 As shown, multiple strip holes 312a are arrayed on the second support plate 312. The strip holes 312a are parallel to each other and all parallel to the roller 212, so that the second support plate 312 can be bent in the extension direction of the strip holes 312a, while having a certain strength in the extension direction perpendicular to the extension direction of the strip holes 312a, and is not easily deformed.

[0086] For example, the flexible support plate 31 can be a stainless steel structural component, such as stainless steel SUS316 or SUS430.

[0087] like Figure 8 As shown, the display device also includes a recycling plate 50. The recycling plate 50 is located on the second side of the second housing 20 and is connected to the edge of the flexible display panel 30. Multiple tension bars 40 are connected to the recycling plate 50.

[0088] By setting up the recovery plate 50, the force of the multiple tension bars 40 can be applied more evenly to the flexible display panel 30, making the flexible display panel 30 flatter and its movement more stable.

[0089] Figure 10 This is a partially exploded structural diagram of a display device provided in an embodiment of this disclosure. For example... Figure 10 As shown, the surface of the recycling plate 50 has a plurality of first columnar protrusions 51 and a plurality of second columnar protrusions 52, which are located on opposite sides of the recycling plate 50. The plurality of first columnar protrusions 51 and the plurality of second columnar protrusions 52 are arranged along the side of the recycling plate 50.

[0090] The connecting plate 313 has multiple first connecting holes 313a, which are arranged along the side of the connecting plate 313 away from the second support plate 312. These first connecting holes 313a are fitted over multiple first columnar protrusions 51. Connecting holes can also be provided on the flexible display panel 30 at positions corresponding to the first connecting holes 313a, and these holes are fitted over the first columnar protrusions 51. The ends of the tensioning strips 40 have second connecting holes 40a, which are respectively fitted over multiple second columnar protrusions 52. The force applied by the multiple tensioning strips 40 is applied to the recovery plate 50 through the multiple second columnar protrusions 52, and then from the recovery plate 50 to the flexible support plate 31 through the multiple first columnar protrusions 51, making the force on the flexible support plate 31 more uniform.

[0091] Optionally, the recycling plate 50 and the flexible support plate 31 can also be bonded together, for example, with double-sided tape, foam adhesive, or other adhesive layers, to avoid excessive stress and deformation at the first connecting hole 313a. The first connecting hole 313a cooperates with the first columnar protrusion 51, which can also prevent the adhesive layer from slipping after the display device has been used for a long time, ensuring the reliability of the connection between the flexible support plate 31 and the recycling plate 50, and ensuring the flatness of the flexible display panel 30.

[0092] Figure 11 This is a schematic diagram of the structure of a display device provided in an embodiment of this disclosure. Figure 11 As shown, the display device also includes a baffle 60. The baffle 60 is located on the second side of the second housing 20. The baffle 60 is connected to the second housing 20. The flexible display panel 30 is located on the side of the baffle 60 closest to the second housing 20.

[0093] By setting the baffle 60, the portion of the flexible display panel 30 that is bent to the second side of the second housing 20 can be protected, thus preventing damage to the flexible display panel 30.

[0094] like Figure 10 As shown, a rolling element 53 is provided on the recycling plate 50. The rolling element 53 can rotate relative to the recycling plate 50. The rolling element 53 is in rolling engagement with the baffle 60.

[0095] For example, the rolling element 53 is cylindrical, and the surface of the recycling plate 50 has a groove 50a, in which part of the rolling element 53 is located.

[0096] The rolling element 53 not only serves as a support, preventing the recycling plate 50 and the flexible display panel 30 from directly contacting the baffle 60 and preventing scratches on the surface of the flexible display panel 30, but also, during the relative pushing and pulling of the first housing 10 and the second housing 20, when the recycling plate 50 moves, the rolling element 53 rolls on the surface of the baffle 60, resulting in low resistance and smooth movement.

[0097] Figure 12 This is a schematic diagram illustrating the connection between a first housing and a second housing according to an embodiment of this disclosure. Figure 12 As shown, the display device also includes a guide rail 71 and a slider 72. The slider 72 is slidably connected to the guide rail 71. One of the first housing 10 and the second housing 20 is connected to the guide rail 71, and the other is connected to the slider 72, so that the first housing 10 and the second housing 20 can move relative to each other more smoothly.

[0098] The display device may include multiple guide rails 71 and multiple sliders 72. The guide rails 71 and sliders 72 are arranged in a one-to-one correspondence, and the multiple guide rails 71 are parallel to each other. For example, in an embodiment of this disclosure, the display device includes two guide rails 71 and two sliders 72.

[0099] like Figure 12 As shown, multiple guide rails 71 are located in the first housing 10, and one end of each guide rail 71 is close to the opening 10a. The guide rails 71 are connected to the first housing 10, for example, by screws. A slider 72 is slidably connected to the guide rails 71. The slider 72 is connected to the second housing 20, for example, by screws. In this embodiment, the second housing 20 further includes a slider fixing plate 25, which is located at the end of the roller bracket 211 and connected to the roller bracket 211. The slider 72 is connected to the slider fixing plate 25 by screws.

[0100] Figure 13 This is a schematic diagram of the assembly of a slider and a guide rail according to an embodiment of this disclosure. Figure 13As shown, the slider 72 has a clamping groove 72a, and the guide rail 71 is located in the clamping groove 72a. The clamping groove 72a and the guide rail 71 cooperate to allow the slider 72 to move along the guide rail 71. Stops 711 can be connected to both ends of the guide rail 71 to limit the range of movement of the slider 72 and prevent the slider 72 from dislodging from the end of the guide rail 71.

[0101] The sidewall of the clamping groove 72a has a first groove 72b, in which a ball 721 is disposed. The sidewall of the guide rail 71 has a second groove 71a extending along its length direction, with the first groove 72b and the second groove 71a opposite each other, and the ball 721 is partially located in the second groove 71a.

[0102] By setting ball bearings 721 in the first groove 72b and the second groove 71a, when the slider 72 moves relative to the guide rail 71, the ball bearings 721 roll in the second groove 71a, thereby reducing the frictional resistance on the slider 72 and making the movement of the slider 72 smoother.

[0103] Each first groove 72b may be provided with multiple balls 721, which are arranged along the length of the first groove 72b. When the slider 72 is installed on the guide rail 71, the extension direction of the first groove 72b is the same as the extension direction of the second groove 71a, and the multiple balls 721 are partially located in the second groove 71a. When the slider 72 slides relative to the guide rail 71, the multiple balls 721 roll in the second groove 71a.

[0104] Figure 14 This is a schematic diagram illustrating the cooperation between a slider and a guide rail according to an embodiment of this disclosure. Figure 14 As shown, the cross-sections of the first groove 72b and the second groove 71a are both arc-shaped. The radii of the cross-sections of the first groove 72b and the second groove 71a are the same as the radius of the ball 721.

[0105] The fitting accuracy between the ball bearing 721 and the first groove 72b and the second groove 71a affects the smoothness of the slider 72's operation. The radius of the cross-section of the first groove 72b and the radius of the cross-section of the second groove 71a are the same as the radius of the ball bearing 721, so that the ball bearing 721 forms a zero-gap contact with the first groove 72b and the second groove 71a, ensuring that the slider 72 can move smoothly.

[0106] Optionally, the cross-section of the second groove 71a is semi-circular.

[0107] Since the cross-section of the second groove 71a is semi-circular, the slider 72 can withstand the load along the depth direction of the groove 72a, making it difficult for the slider 72 to detach from the guide rail 71. This helps to extend the service life of the slider 72 and the guide rail 71, as well as the load-bearing capacity of the guide rail 71.

[0108] By adjusting the diameter of the ball bearing 721, the fit accuracy between the groove 72a of the slider 72 and the guide rail 71 can also be adjusted. For example, the groove 72a and the guide rail 71 can have a transition fit, i.e., a clearance fit or an interference fit. For example, the clearance can be -3 micrometers to 3 micrometers, to prevent excessive looseness between the slider 72 and the guide rail 71, which could affect the relative movement between the first housing 10 and the second housing 20.

[0109] like Figure 13 As shown, the display device also includes two end caps 73. The two end caps 73 are located at opposite ends of the clamping groove 72a. Both end caps 73 are connected to the slider 72, for example, by screws.

[0110] End caps 73 are located at both ends of the clamping groove 72a to shield the ball 721. This not only prevents the ball 721 from falling out of the slider 72, but also provides a seal to prevent dust and other foreign objects from entering the first groove 72b and affecting the rolling of the ball 721.

[0111] In some examples, the display device may also include a drive structure connected to the slider 72 to drive the slider 72 to slide along the guide rail 71. For example, the drive structure may include a motor. By configuring the drive structure to drive the slider 72, the second housing 20 can automatically extend and retract relative to the first housing 10.

[0112] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
