Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a display device. Background Technology

[0002] Currently, some electronic devices incorporate rollable screens. Rollable screens make electronic devices easier to store and suitable for various applications. Rollable screens require a support structure on the backlight side of the flexible screen. When the screen is bent, this support structure is subjected to stress. If the support structure is too rigid, the flexible screen is difficult to bend, resulting in higher stress within the support structure during bending and a shorter lifespan for the rollable screen. Conversely, if the support structure is too rigid, it provides poor support for the flexible screen, causing it to dent towards the support structure, resulting in a poor user experience. Summary of the Invention

[0003] This application provides a display device for solving the problem of difficulty in determining the stiffness of the support structure for a rollable screen.

[0004] This application provides a display device, the display device comprising:

[0005] Flexible screen;

[0006] A first support member, along the length direction of the display device, a plurality of first support members are arranged side by side on one side of the flexible screen;

[0007] The second support member, along the length direction of the display device, has a plurality of second support members disposed on the side of the first support member away from the flexible screen;

[0008] The second support member is rotatably connected to the first support member. When the second support member is parallel to the first support member, the display device is in a first state. When the second support member rotates to a preset angle, the display device is in a second state. When the display device is in the first state, the flexible screen can be bent.

[0009] When the second support member is parallel to the first support member, the display device is in a first state. The angle between adjacent first support members can be adjusted, allowing the flexible screen to bend towards the direction where the first support members are located. After the second support member rotates by a preset angle, the second support member intersects with the first support member, and the display device is in a second state. At this time, both ends of the second support member can abut against the adjacent first support members, thereby limiting the relative position between the adjacent first support members and keeping the flexible screen in an unfolded state. By changing the angle between the first and second support members, the first and second states of the display device are switched. By changing the angle between adjacent first support members, the flexible screen can bend, reducing the rigidity requirements of the first and second support members on the display device.

[0038] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0039] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0040] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0041] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0042] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a display device, which includes a flexible screen 1, a first support member 2, and a second support member 3. Along the length direction X of the display device, a plurality of first support members 2 are arranged side by side on one side of the flexible screen 1, and along the length direction X of the display device, a plurality of second support members 3 are arranged on the side of the first support members 2 away from the flexible screen 1. The second support members 3 are rotatably connected to the first support members 2. When the second support members 3 are parallel to the first support members 2, the display device is in a first state. When the second support members 3 are rotated to a preset angle, the display device is in a second state. When the display device is in the first state, the flexible screen 1 can be bent.

[0044] The flexible screen 1 includes a light-emitting side and a backlight side. The light-emitting side of the flexible screen 1 is used for display. The first support member 2 and the second support member 3 are located on the backlight side of the flexible screen 1, reducing the impact of the first support member 2 and the second support member 3 on the display effect of the flexible screen 1. When the display device is in the first state, the first support member 2 and the second support member 3 are parallel to each other, and the flexible screen 1 can be bent towards the backlight side. When the display device is in the second state, the first support member 2 and the second support member 3 intersect each other, and the flexible screen 1 can remain in the unfolded state.

[0045] The first support member 2 is arranged side by side on one side of the flexible screen 1. When the second support member 3 is parallel to the first support member 2, the included angle between adjacent first support members 2 can be changed, allowing the flexible screen 1 to bend towards the side where the first support member 2 is located. When the flexible screen 1 bends, the first support member 2 and the second support member 3 experience less or no stress, which helps to improve the service life of the first support member 2 and the second support member 3. After the second support member 3 rotates relative to the first support member 2 to a preset angle, the two first support members 2 located on both sides of the first support member 2 where the second support member 3 is located abut against the two ends of the second support member 3, and the display device is in a second state. The second support member 3 restricts the relative position between adjacent first support members 2, keeping the flexible screen 1 in an unfolded state.

[0046] In one possible embodiment, both the first support member 2 and the second support member 3 can be made of rigid materials. The first support member 2, being made of rigid material, can support the flexible screen 1, reducing the possibility of the flexible screen 1 denting and improving its display effect. Multiple first support members 2 are arranged side-by-side on one side of the flexible screen 1. When the display device is in the first state, the bending process of the flexible screen 1 changes the included angle between adjacent first support members 2 without altering the shape of the first support members 2. Therefore, the rigidity of the first support members 2 has a minimal impact on the bending of the flexible screen 1. The second support member 3, also made of rigid material, can limit the relative position between adjacent first support members 2 when the display device is in the second state, thus improving the stability of the display device in the unfolded state. When the display device is in either the first or second state, the first support members 2 and 3 do not need to deform; therefore, the rigidity of the first support members 2 and 3 has a minimal impact on the bending and unfolding process of the display device.

[0047] like Figure 1 and Figure 2 As shown, in one possible embodiment, the second support member 3 is connected to the side of the first support member 2 away from the flexible screen 1, and one of the two adjacent first support members 2 is connected to the second support member 3.

[0048] On the backlight side of the flexible screen 1, along the length direction X of the display device, the first support members 2 are arranged side by side, and the second support members 3 are arranged at intervals on the side of the first support members 2 away from the flexible screen 1. There is a first support member 2 between adjacent second support members 3, and the two first support members 2 located at both ends of the flexible screen 1 are not provided with second support members 3 on the side away from the flexible screen 1.

[0049] After the second support member 3 rotates relative to the first support member 2, the display device is in the second state. At this time, both ends of the second support member 3 abut against the first support members 2 located on both sides of the second support member 3. Therefore, a single second support member 3 can restrict the relative position between three adjacent first support members 2. The second support members 3 are spaced apart on the side of the first support member 2 away from the flexible screen 1, which can restrict the relative position of multiple first support members 2 located on one side of the flexible screen 1, keeping the flexible screen 1 in an unfolded state. At the same time, it can also reduce the number of second support members 3, which is beneficial to reducing the production cost of the display device. When the display device is in the first state, the flexible screen 1 bends in the direction where the first support member 2 and the second support member 3 are located. If the distance between the second support members 3 is small, there is a possibility of interference between adjacent second support members 3 during the bending process of the flexible screen 1. The spaced arrangement of the second support members 3 can increase the distance between adjacent second support members 3 and reduce the possibility of interference between adjacent second support members 3. If second support members 3 are also provided on the first support members 2 at both ends of the flexible screen 1, when the display device is in the second state, the second support members 3 and the first support members 2 intersect each other. Along the length direction X of the display device, the second support members 3 at both ends will protrude from the flexible screen 1, which may interfere with other structures in the display device. The reliability of the display device can be improved if the two first support members 2 at both ends of the flexible screen 1 are not provided with second support members 3.

[0050] like Figure 1 , Figure 2 and Figure 4 As shown, in one possible embodiment, the first support member 2 is provided with a mounting member 21 on the side away from the flexible screen 1, and the second support member 3 is rotatably connected to the first support member 2 through the mounting member 21.

[0051] The mounting component 21 can be cylindrical and located at the center of the first support component 2. A circular through hole or blind hole is provided at the center of the second support component 3, so that the mounting component 21 can extend into the second support component 3, thereby connecting the first support component 2 and the second support component 3.

[0052] The first support member 2 is provided with a mounting member 21 for connecting with the second support member 3. This mounting member restricts the relative position of the first support member 2 and the second support member 3, reducing the possibility of the second support member 3 moving relative to the first support member 2 along the length direction X or width direction Y of the display device, thus improving the reliability of the display device. The mounting member 21 is cylindrical, which facilitates the rotation of the second support member 3 relative to the first support member 2 after the mounting member 21 extends into the second support member 3.

[0053] like Figure 3 and Figure 4As shown, in one possible embodiment, the width of the first support member 2 gradually decreases along the direction from the flexible screen 1 to the first support member 2.

[0054] Along the thickness direction Z of the display device, the cross-section of the first support member 2 is an isosceles trapezoid. Along the direction away from the flexible screen 1, the cross-sectional area of ​​the first support member 2 gradually decreases. When the flexible screen 1 is bent, the side walls of adjacent first support members 2 abut against each other.

[0055] When the flexible screen 1 is bent toward the direction where the first support member 2 is located, the cross-sectional area of ​​the first support member 2 gradually decreases. This reduces the possibility of interference between adjacent first support members 2 on the side furthest from the flexible screen 1, which helps improve the reliability of the display device during bending. After the flexible screen 1 is bent, the sidewalls of adjacent first support members 2 abut against each other, which limits the bending angle of the flexible screen 1 and reduces the possibility of damage to the flexible screen 1 due to excessive bending. The cross-section of the first support member 2 is an isosceles trapezoid. When the flexible screen 1 is bent, the included angles between multiple first support members 2 are consistent, so that the stress generated in the flexible screen 1 is evenly distributed, reducing the risk of damage to the flexible screen 1.

[0056] In one possible embodiment, the angle between the side wall and the bottom wall of the first support member 2 can be set according to the angle at which the flexible screen 1 needs to be bent, so that the first support member 2 can be adapted to a variety of display devices.

[0057] like Figure 1 and Figure 3 As shown, in one possible embodiment, the size of the second support member 3 is smaller than the size of the first support member 2 along the length direction X of the display device.

[0058] Along the thickness direction Z of the display device, the cross-section of the second support member 3 can be trapezoidal, rectangular, etc. If the cross-section of the second support member 3 is trapezoidal, the width of the second support member 3 gradually decreases along the direction away from the first support member 2. Along the length direction X of the display device, the size of the second support member 3 is smaller than the size of the side of the first support member 2 away from the flexible screen 1.

[0059] When the display device is in the first state, the flexible screen 1 can be bent toward the side where the first support member 2 is located. The second support member 3 is located on the side of the first support member 2 away from the flexible screen 1. When the flexible screen 1 is bent, the change in distance between adjacent second support members 3 is greater than the change in distance between adjacent first support members 2. Along the length direction X of the display device, the size of the second support member 3 is smaller than that of the first support member 2, which increases the spacing between adjacent second support members 3. When the flexible screen 1 is bent, the possibility of interference between adjacent second support members 3 can be reduced.

[0060] like Figure 5 , Figure 6 and Figure 7 As shown, in one possible embodiment, along the length direction X of the display device, the first support member 2 located at both ends of the flexible screen 1 does not have a second support member 3 on the side away from the flexible screen 1, while the other first support members 2 are provided with second support members 3 on the side away from the flexible screen 1, and the second support member 3 can rotate relative to the first support member 2.

[0061] When the second support member 3 is parallel to the first support member 2, the size of the second support member 3 along the length X of the display device is smaller than the size of the first support member 2. This reduces the possibility of interference between adjacent second support members when the flexible screen 1 bends towards the direction where the first support member 2 is located. When the second support member 3 intersects with the first support member 2, both ends of the second support member 3 will abut against the adjacent first support member 2. Except for the two first support members 2 located at both ends of the flexible screen 1, the ends of the other first support members 2 away from the flexible screen 1 are provided with second support members 3, which helps to improve the stability of the display device when it is in the unfolded state. The two first support members 2 located at both ends of the flexible screen 1 are not provided with second support members 3. When the flexible screen is in the second state, this reduces the possibility that the second support members 3 will protrude from the flexible screen 1 along the length X of the display device.

[0062] like Figure 8 and Figure 9 As shown, in one possible embodiment, the display device further includes a drive member 4, which is connected to the second support member 3 and is capable of moving along the length direction X of the display device to drive the second support member 3 to rotate.

[0063] Along the width direction Y of the display device, the drive member 4 is located on one or both sides of the second support member 3 and can move relative to the first support member 2. The end of the second support member 3 protrudes from the first support member 2 and is connected to the drive member 4. When the drive member 4 moves relative to the first support member 2, it can drive the second support member 3 to rotate relative to the first support member 2.

[0064] The first support member 2 and the second support member 3 are rotatably connected. The driving member 4 moves along the length direction X of the display device, which can drive the second support member 3 to rotate relative to the first support member 2, making it easier for the display device to switch between the first state and the second state.

[0065] like Figure 8 and Figure 9 As shown, in one possible embodiment, the second support member 3 includes a connecting portion 31 that protrudes from the first support member 2 along the width direction Y of the display device and is at least partially connected to the drive member 4.

[0066] Along the thickness direction Z of the display device, the outer contour of the connecting part 31 can be arc-shaped. When the driving member 4 moves along the length direction X of the display device, the connecting part 31 can rotate relative to the driving member 4, so that the second support member 3 can rotate relative to the first support member 2.

[0067] The second support member 3 is connected to the drive member 4 through the connecting part 31. The drive member 4 drives the second support member 3 to rotate relative to the first support member 2 by moving relative to the first support member 2. Along the width direction Y of the display device, the connecting part 31 protrudes from the first support member 2, which helps to reduce the possibility of interference between the drive member 4 and the first support member 2 during the movement.

[0068] like Figure 10 and Figure 11 As shown, in one possible embodiment, the driving member 4 includes a plurality of main body parts 41, which are rotatably connected along the length direction X of the display device.

[0069] Along the length direction X of the display device, the number of main body parts 41 is the same as the number of second support members 3, and they are arranged correspondingly to the second support members 3. Along the width direction Y of the display device, the second support members 3 are connected to the main body parts 41 through the connecting part 31. Along the length direction X of the display device, adjacent main body parts 41 are rotatably connected to form a driving member 4.

[0070] When the display device is in the first state, the flexible screen 1 can be bent toward the side where the first support member 2 is provided. During the bending process, the first support member 2 and the second support member 3 will move with the flexible screen 1. The main body part 41 in the driving member 4 is connected to the second support member 3. During the movement of the second support member 3, the main body part 41 will move with the second support member 3. Adjacent main body parts 41 can be rotatably connected, and the included angle between adjacent main body parts 41 can be adjusted so that the driving member 4 can bend with the second support member 3, reducing the possibility of the second support member 3 detaching from the driving member 4.

[0071] like Figure 8 and Figure 9 As shown, in one possible embodiment, a limiting part 411 is provided on the side of the main body 41 facing the second support member 3, and the second support member 3 can extend into the limiting part 411.

[0072] The limiting part 411 may include a first limiting block 411a and a second limiting block 411b. Along the length direction X of the display device, the first limiting block 411a and the second limiting block 411b are spaced apart on the side of the main body 41 facing the second support member 3. The size of the gap between the first limiting block 411a and the second limiting block 411b is the same as the size of the connecting part 31, so that the first limiting block 411a and the second limiting block 411b abut against the two sides of the connecting part 31. The outer contour of the connecting part 31 is arc-shaped, so that the connecting part 31 can rotate relative to the first limiting block 411a and the second limiting block 411b. When the driving member 4 moves along the length direction X of the display device, the connecting part 31 can move relative to the first limiting block 411a and the second limiting block 411b, but is always located between the first limiting block 411a and the second limiting block 411b.

[0073] The second support member 3 extends into the limiting part 411 and restricts the relative position between the main body part 41 and the second support member 3 along the length direction X of the display device. When the driving member 4 moves along the length direction X of the display device, the main body part 41 can drive the connecting part 31 to move along the length direction X of the display device. At the same time, the connecting part 31 is located at the end of the second support member 3 and can rotate relative to the limiting part 411, so that the second support member 3 rotates relative to the first support member 2.

[0074] like Figure 10 and Figure 11 As shown, in one possible embodiment, the main body 41 includes a protrusion 412 and a recess 413. Along the length direction X of the display device, the protrusion 412 and the recess 413 are located on both sides of the main body 41. In two adjacent main bodies 41, the protrusion 412 of one extends into the recess 413 of the other, and the protrusion 412 and the recess 413 are rotatably connected.

[0075] Along the width direction Y of the display device, connection holes 414 are provided on both sides of the recessed portion 413 and the protrusion 412. After the protrusion 412 extends into the recessed portion 413, the connection holes 414 located on the protrusion 412 and the connection holes 414 located on both sides of the recessed portion 413 overlap each other. A fixing pin is inserted into the connection hole 414 so that the protrusion 412 of one of the two adjacent main body portions 41 is rotatably connected to the recessed portion 413 of the other.

[0076] Both the protrusion 412 and the recess 413 extend along the length direction X of the display device and along the width direction Y of the display device. The recess 413 has sidewalls on both sides. The protrusion 412 of one of the adjacent main body parts 41 extends into the recess 413 of the other, which can restrict the relative position between the two adjacent main body parts 41 along the width direction Y of the display device. Fixing pins are inserted into the connecting holes 414 on the overlapping protrusion 412 and the connecting holes 414 on the sidewalls of the recess 413, which can restrict the relative position of the two main body parts 41 along the length direction X and the thickness direction Z of the display device, improving the reliability of the drive member 4. At the same time, it enables the rotatable connection of the two adjacent main body parts 41, allowing the drive member 4 to bend along the thickness direction Z of the display device. When the display device is in the first state, it reduces the possibility of the drive member 4 disengaging from the second support member 3.

[0077] like Figure 10 and Figure 11 As shown, in one possible embodiment, the outer contours of the upper surfaces of the protrusion 412 and the recess 413 are arc-shaped along the direction from the flexible screen 1 to the first support member 2. When the display device is in the first state, the flexible screen 1 bends along the direction from the flexible screen 1 to the first support member 2. At this time, the main body 41 moves with the second support member 3, causing the driving member 4 to also bend along the direction from the flexible screen 1 to the first support member 2. The outer contours of the upper surfaces of the protrusion 412 and the recess 413 are arc-shaped. During the bending process of the driving member 4, the possibility of interference between the edge of the recess 413 and the bottom wall of the protrusion 412 or interference between the side wall of the recess 413 and another main body 41 is reduced, which facilitates the bending of the driving member 4.

[0078] In one possible embodiment, the display device includes a housing with a limiting device connected to the drive member 4 for limiting the position of the drive member 4.

[0079] The flexible screen 1, first support member 2, second support member 3, and drive member 4 of the display device are all located within a housing. A control device and a limiting device may also be provided within the housing. The control device is electrically connected to the drive member 4 and is used to control the movement of the drive member 4 relative to the first support member 2, allowing the display device to switch between a first state and a second state. The limiting device is connected to the drive member 4 and, after the drive member 4 moves to a preset position, the limiting device can restrict the position of the drive member 4, keeping the display device in either the first or second state.

[0080] This application provides a display device including a flexible screen 1, a first support member 2, and a second support member 3. Along the length X of the display device, multiple first support members 2 are arranged side-by-side on one side of the flexible screen 1, and the second support members 3 are located on the side of the first support members 2 away from the flexible screen 1. The second support member 3 is rotatably connected to the first support members 2. When the second support member 3 is parallel to the first support member 2, the display device is in a first state, and the included angle between adjacent first support members 2 can be adjusted, allowing the flexible screen 1 to bend. When the second support member 3 rotates to a preset angle, the display device is in a second state, where the second support member 3 restricts the relative position between the first support members 2, causing the flexible screen 1 to be in an unfolded state.

[0081] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
