Moreover, if the component is turned over, the layer or a region will be "below" or "beneath" another layer or another region.

[0029] It is obvious to those skilled in the art that various modifications and changes can be made in the present application without departing from the spirit or scope of the present application. Therefore, the present application is intended to cover modifications and changes of the present application that fall within the scope of the corresponding claims (technical solutions for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present application can be combined with each other without contradiction.

[0030] In the prior art, a foldable display device has a main screen and a sub-screen respectively located on both sides of a supporting structure. Due to the structural limitations of the existing display device, when the display device is bent, the tensile stress of the screen itself causes abnormal display on the sub-screen.

[0031] In order to solve the above problems, the display device provided in the present application utilizes a accommodating groove provided on the first rotating shaft to absorb the sliding redundancy caused by the bending of the flexible display panel, that is, part of the flexible display panel is moved into the accommodating groove through the first rotating shaft, which will not affect the display area or position of the part of the flexible display panel located on the second surface of the display device, thereby ensuring the display effect of the display device.

[0032] The present application provides a display device and an electronic device. Figures 1 to 6 Various embodiments of a display device and an electronic device are described.

[0033] See also Figures 1 to 4 A display device provided in an embodiment of the present application has a flat state and a bent state. The display device includes a support structure 11 and a flexible display panel 2. The support structure 11 includes a first part 11 and a second part 12 that are rotatably connected. A first rotating shaft 3 is provided at a free end of one of the first part 11 and the second part 12. The support structure 11 includes a first surface F1 and a second surface F2 that are opposite to each other. The outer peripheral surface of the first rotating shaft 3 includes a receiving groove K. The flexible display panel 2 is arranged on one side of the first surface F1 of the support structure 11 and partially extends to one side of the second surface F2. Along the extension direction of the support structure 11, at least part of the flexible display panel 2 is slidably arranged relative to the support structure 11, and the flexible display panel 2 contacts the first rotating shaft 3 on one side of the support structure 11. In the process of converting from the flat state to the bent state, the first surfaces F1 of the first part 11 and the second part 12 approach each other, the flexible display panel 2 slides along the extension direction of the support structure 11, and the first rotating shaft 3 drives part of the flexible display panel 2 to move into the receiving groove K.

[0034] The display device provided in an embodiment of the present invention includes a supporting structure 11 and a flexible display panel 2. The flexible display panel 2 is arranged on a first surface F1 side of the supporting structure 11 and partially extends to a second surface F2 side. That is, both the first surface F1 and the second surface F2 of the supporting structure 11 can be displayed in a flat state, and in a bent state, the flexible display panel 2 located on the second surface F2 can be used for display. During the process of converting the display device from a flat state to a bent state, the support structure 11 folds inward so that the first surfaces F1 of the first part 11 and the second part 12 are close to each other, and part of the flexible display panel 2 slides along the extension direction of the support structure 11, and the accommodating groove K of the first rotating shaft 3 is used to absorb the sliding redundancy of the flexible display panel 2 caused by bending, that is, part of the flexible display panel 2 is moved into the accommodating groove K through the first rotating shaft 3, which will not affect the display area or position of the part of the flexible display panel 2 located on the second surface F2 of the display device, thereby ensuring the display effect of the display device, and while realizing the bending of the flexible display panel 2, protecting the flexible display panel 2 from failure caused by the bending, avoiding wrinkles or fractures at the bending portion of the flexible display panel 2 due to bending, thereby improving the service life of the display device.

[0035] It should be noted that the accommodating slot K is directly opened and placed on the first rotating shaft 3. According to the specific width of the flexible display panel 2, the accommodating slot K can penetrate the first rotating shaft 3 along the axial direction of the first rotating shaft 3. In the radial direction along the first rotating shaft 3, the accommodating slot K can be an arc-shaped slot structure. The specific shape and size of the arc-shaped slot structure need to be set according to the size of the flexible display panel 2 to be accommodated, so as to ensure that the arc-shaped slot structure can accommodate the redundant part of the flexible display panel 2 caused by bending.

[0036] See also Figures 4 to 5 The size of the arc-shaped slot structure should not be too small, otherwise it may not be able to accommodate all the redundant parts, nor should it be too large, otherwise it may affect the stability of the rotation of the first shaft 3. Optionally, the central angle of the arc-shaped slot structure is greater than or equal to 90° and less than or equal to 135°. For example, the central angle of the arc-shaped slot structure can be equal to any one of 90°, 105°, 120°, and 135°.

[0037] In this embodiment, the first part 11 and the second part 12 of the support structure 11 can be rotatably connected via a second rotating shaft, or can be rotatably connected in other ways, such as hinge connection, etc., as long as the relative rotation of the first part 11 and the second part 12 can be achieved. The free end of the first part 11 and the second part 12 refers to an end that is not rotatably connected between the first part 11 and the second part 12. For example, when the first part 11 and the second part 12 can be rotatably connected via a second rotating shaft, the free ends of the first part 11 and the second part 12 are the ends that are respectively away from the second rotating shaft.

[0038] The flexible display panel 2 may be an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) or a micro flat display panel (Micro-OLED or Micro-LED).

[0039] See also Figure 2 or Figure 3 In some optional embodiments, along the extension direction of the flexible display panel 2, the flexible display panel 2 includes a first display portion 21 and a second display portion 22 connected to each other, the first display portion 21 is at least partially located on the first surface F1, and the second display portion 22 is at least partially located on the second surface F2.

[0040] In this embodiment, the flexible display panel 2 can be bent and extended from the first surface F1 of the support structure 11 to the second surface F2 at a position where the first rotating shaft 3 is provided. The flexible display panel 2 located on the first surface F1 and the flexible display panel 2 located on the second surface F2 can adopt a bending integrated design, that is, the first display portion 21 and the second display portion 22 of the flexible display panel 2 are connected as an integrated structure, which can be controlled by a single control chip or a single circuit board, effectively reducing the film thickness of the display device. The control chip or circuit board can be provided at one end of the first display portion 21 away from the second display portion 22, and can be bent to the back of the display surface of the first display portion 21.

[0041] Optionally, the first rotating shaft 3 is located at the free end of the second part 12, that is, the junction of the first display part 21 and the second display part 22 is located at the free end of the second part 12, and the flexible display panel 2 extends from the free end of the second part 12 to the second surface F2 of the second part 12 to form a second display part 22 on the second surface F2 of the second part 12, thereby realizing the main and sub-screen display of the display device.

[0042] Optionally, the first display portion 21 and the second display portion 22 are connected via wiring, that is, a signal connection is achieved between the first display portion 21 and the second display portion 22, which facilitates unified control.

[0043] See also Figures 2 to 3 In some optional embodiments, the first display portion 21 includes a first sub-display portion 211 and a second sub-display portion 212 that are connected to each other. The first sub-display portion 211 is disposed on the first portion 11 and is fixedly connected to the first portion 11, and the second sub-display portion 212 is disposed on the second portion 12 and is slidably disposed relative to the second portion 12.

[0044] During the process of converting the display device from a flat state to a bent state, since the first sub-display portion 211 and the first portion 11 are fixedly connected, the first sub-display portion 211 remains fixed relative to the first portion 11, while the second sub-display portion 212 will slide relative to the second portion 12 due to the bending, and slide toward the free end of the second portion 12 where the first rotating shaft 3 is provided, and the sliding portion of the second sub-display portion 212 is moved to the accommodating groove K by the rotation of the first rotating shaft 3, so as to avoid the generation of accumulated wrinkles, and the accommodating groove K of the first rotating shaft 3 is used to absorb the redundancy caused by the bending.

[0045] Of course, according to actual needs, the first sub-display portion 211 can be slidably arranged relative to the first portion 11, while the second sub-display portion 212 is fixedly connected to the second portion 12. In this case, the first rotating shaft 3 needs to be correspondingly arranged at the free end of the first portion 11 to adjust the sliding portion of the first sub-display portion 211.

[0046] Optionally, the first sub-display portion 211 and the first part 11 are connected via a first adhesive layer 4 , and the first adhesive layer 4 may be made of adhesive materials such as optical adhesive, double-sided adhesive, and acrylic adhesive to fix the first sub-display portion 211 .

[0047] See also Figures 4 to 5 In some optional embodiments, the second display portion 22 is disposed on the second part 12 and is fixedly connected to the second part 12, that is, there will be no relative movement between the second display portion 22 and the second part 12, so as to avoid the position of the second display portion 22 changing during the bending process of the display device, thereby affecting the display effect.

[0048] Optionally, the second sub-display portion 212 and the second part 12 are connected via a second adhesive layer 6 , and the second adhesive layer 6 may be made of adhesive materials such as optical adhesive, double-sided adhesive, and acrylic adhesive to fix the second sub-display portion 212 .

[0049] See also Figure 5 to Figure 6 In some optional embodiments, the outer circumferential surface of the first rotating shaft 3 is provided with first clamping portions T1 which are arranged at intervals along the circumferential direction and extend in the radial direction, and the first display portion 21 is provided with second clamping portions T2 which are arranged at intervals along the extension direction of the first display portion 21 and extend in a direction perpendicular to the extension direction of the first display portion 21 on the side facing the first rotating shaft 3; the second clamping portions T2 can be clamped in the interval between adjacent first clamping portions T1.

[0050] It can be understood that the outer periphery of the first rotating shaft 3 can form a gear-like structure by setting the first clamping portion T1. When the first display portion 21 slips relative to the supporting structure 11, since the second clamping portion T2 can be clamped in the gap between adjacent first clamping portions T1, it can interact with the first clamping portion T1 to convert the slip of the first display portion 21 into the rotation of the first rotating shaft 3, and the rotation of the first rotating shaft 3 can be used to rotate the redundant part of the first display portion 21 generated by the slip into the accommodating groove K, so as to avoid the generation of accumulated wrinkles, and use the accommodating groove K of the first rotating shaft 3 to absorb the redundancy caused by bending.

[0051] In this embodiment, the first clamping portion T1 can be an integral structure with the first rotating shaft 3 for easy setting, or the first clamping portion T1 can be additionally provided on the outer circumferential surface of the first rotating shaft 3 by means of a welding machine, bolt connection, etc., so as to facilitate replacement or maintenance of the first clamping portion T1, and the second clamping portion T2 can be provided only on the back of the second sub-display portion 212 to facilitate the clamping engagement of the first clamping portion T1 and the second clamping portion T2 on the first rotating shaft 3.

[0052] Optionally, the second clamping portion T2 may be in the form of a metal chain, for example, a steel chain, and the extension direction of the metal chain intersects with the extension direction of the flexible display panel 2 .

[0053] The first clamping portion T1 and the second clamping portion T2 are clamped together to improve the stability of the flexible display panel 2 during movement, ensuring that the sliding direction and distance of the first display portion 21 are within a predetermined range.

[0054] Optionally, the interval between adjacent first clamping portions T1 is equal to the length of the second clamping portion T2 along the extension direction of the first display portion 21, that is, the second clamping portion T2 can be just inserted into the interval between adjacent first clamping portions T1, thereby improving the accuracy and stability of the clamping between a clamping portion and a second clamping portion T2.

[0055] In some optional embodiments, a flexible substrate is provided between the second sub-display portion 212 and the second portion 12 , and the second clamping portion T2 is provided on the flexible substrate.

[0056] In this embodiment, the flexible substrate and the second sub-display portion 212 can be fixedly connected, that is, the flexible substrate can move together with the second sub-display portion 212, and the second clamping portion T2 can be formed on the flexible substrate through patterning processes such as photolithography and laser cutting to facilitate clamping with the first clamping portion T1 on the first rotating shaft 3.

[0057] The second clamping portion T2 may also be disposed on the original base substrate of the second sub-display portion 212 , and no additional film layer is required to form the second clamping portion T2 , thereby reducing the process flow and the cost.

[0058] Optionally, the material of the flexible substrate may be polyimide, polystyrene, polyethylene terephthalate, polyparaxylene, polyethersulfone or polyethylene naphthalate.

[0059] See also Figure 6 In some other optional embodiments, a metal layer 5 is provided between the second sub-display portion 212 and the second portion 12 , and the second clamping portion T2 is provided on the metal layer 5 .

[0060] In this embodiment, the second clamping portion T2 can be prepared using a relatively hard and non-deformable metal layer 5 to prevent the second clamping portion T2 from being deformed or damaged during use, thereby improving the stability and service life of the second clamping portion T2. ​​Optionally, the metal layer 5 includes a steel metal layer 5.

[0061] Optionally, both the first clamping portion T1 and the second clamping portion T2 are in a boss structure, so as to facilitate the mutual clamping therebetween.

[0062] Optionally, the cross-section of the boss structure is at least one of a rectangle, a trapezoid, and a triangle.
