[0034] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0035] Currently, the application of flexible display technology in mobile phones, laptops, and car displays is becoming increasingly mature. In order to expand the application market, the technology of applying flexible display technology to spliced ​​large-size screens is gradually maturing.

[0036] To ensure screen flatness and bottom support, a 4 to 6mm thick aluminum support plate is laminated to the back of the flexible display panel. During the bending process, a large gap exists between the bent portion of the flexible display panel and the aluminum support plate, resulting in a noticeable seam between the flexible display panel and the aluminum support plate, affecting the visual effect.

[0037] The flexible display device, its manufacturing method, and storage medium provided in this application are intended to solve the above technical problems in the prior art.

[0038] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems with specific embodiments. It should be noted that the following embodiments can refer to, draw on, or combine with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be repeated.

[0039] The embodiment of the present application provides a flexible display device. The structural diagram of the flexible display device 100 is shown in FIG. Figures 5 to 7 As shown, it includes: a flexible display panel 10 and a support member 20, the flexible display panel 10 includes a display part 11, a bending part 12 and a non-display part 13 connected in sequence, and the display part 11, the bending part 12 and the non-display part 13 form a support cavity; the support member 20 is located in the support cavity and is fitted with the display part, the bending part and the non-display part; wherein: the non-display part 13 is provided with a first alignment mark 15, and the support member 20 is provided with a second alignment mark 21 corresponding to the first alignment mark 15, and the first alignment mark 15 and the second alignment mark 21 cooperate to align the flexible display panel 10 and the support member 20.

[0040] In the embodiment of the present application, the flexible display panel 10 includes a display portion 11, a bent portion 12, and a non-display portion 13. The display portion 11 is used to display images and is connected to the non-display portion 13 via the bent portion 12. The non-display portion 13 is located on the side of the support member 20 facing away from the display portion 11. The display portion 11, the bent portion 12, and the non-display portion 13 form a support cavity. The support member 20 is located within the support cavity. The support member 20 supports the flexible display panel 10. Moreover, because the support member 20 is arranged in contact with the display portion 11, the bent portion 12, and the non-display portion 13, there is no gap or a small gap between the support member 20 and the inner wall of the support cavity, thereby reducing the gap between the support member 20 and the flexible display panel 10 and enhancing the visual effect.

[0041] In addition, in the embodiment of the present application, since the non-display portion 13 is provided with a first alignment mark 15 and the support member 20 is provided with a second alignment mark 21 corresponding to the first alignment mark 15, the first alignment mark 15 cooperates with the second alignment mark 21 to achieve the purpose of aligning and installing the flexible display panel 10 and the support member 20; and since the display portion 11, the bending portion 12 and the non-display portion 13 are all fitted with the support member 20, alignment is achieved by cooperating with the first alignment mark 15 and the second alignment mark 21, and the flexible display panel 10 is fitted along the outer wall of the support member 20, so that the flexible display panel 10 can be accurately bent, thereby achieving the flexible display panel 10 being accurately aligned, fitted, bent, and installed on the support member 20.

[0042] Moreover, in the embodiment of the present application, by providing a second alignment mark 21 corresponding to the first alignment mark 15 on the support member 20, and realizing alignment installation through the cooperation of the first alignment mark 15 and the second alignment mark 21, it is possible to solve the problem in the prior art that the support member is not light-transmissive, which causes the support member to easily block the alignment mark on the flexible display panel, making it impossible to identify and detect the alignment mark, and making it difficult to perform alignment identification and installation through the two corresponding alignment marks provided on the flexible display panel.

[0043] Optionally, in the embodiment of the present application, the support member 20 is made of aluminum.

[0044] Alternatively, as Figure 5 and Figure 7 As shown, in the embodiment of the present application, the orthographic projection of the first alignment mark 15 on the support member 20 coincides with the second alignment mark 21 .

[0045] With this arrangement, the purpose of aligning the flexible display panel 10 and the support member 20 can be achieved by cooperating with the first alignment mark 15 and the second alignment mark 21 , and the operation is simple.

[0046] It should be noted that projection refers to the use of a set of light rays to project the shape of an object onto a plane. This is called "projection." The resulting image on that plane is also called "projection." Orthographic projection refers to parallel projection lines perpendicular to the projection plane.

[0047] Alternatively, as Figure 3 、 Figure 5 and Figure 7 As shown, in the embodiment of the present application, the display portion 11 is provided with a third alignment mark 16, and the third alignment mark 16 is spaced apart from the first alignment mark 15; the support member 20 is provided with a fourth alignment mark 22 corresponding to the third alignment mark 16; the third alignment mark 16 cooperates with the fourth alignment mark 22 to align and install the flexible display panel 10 and the support member 20.

[0048] In an embodiment of the present application, the display portion 11 is provided with a third alignment mark 16, and the third alignment mark 16 is spaced apart from the first alignment mark 15 to avoid interference; the support member 20 is provided with a fourth alignment mark 22 corresponding to the third alignment mark 16, and the fourth alignment mark 22 is used to align with the third alignment mark 16. By coordinating the third alignment mark 16 and the fourth alignment mark 22, the flexible display panel 10 and the support member 20 can be aligned to facilitate installation.

[0049] In the embodiment of the present application, the first alignment mark 15 cooperates with the second alignment mark 21, and the third alignment mark 16 cooperates with the fourth alignment mark 22, so as to achieve the purpose of aligning and installing the flexible display panel 10 and the support member 20. This arrangement can improve the alignment accuracy, thereby improving the accuracy of installation.

[0050] Alternatively, as Figures 2 to 7 As shown, in the embodiment of the present application, the fourth alignment mark 22 is a avoidance hole opened on the support member 20, and the orthographic projection of the avoidance hole on the display unit 11 covers the third alignment mark 16. That is, the orthographic projection of the third alignment mark 16 on the support member 20 is located in the avoidance hole.

[0051] Alternatively, as Figure 2 、 Figure 4 and Figure 6 As shown, in the embodiment of the present application, the avoidance hole passes through the first support plate 23 .

[0052] The third alignment mark 16 can be accurately observed through the avoidance hole, which facilitates the alignment of the third alignment mark 16 and the avoidance hole, thereby facilitating the alignment of the flexible display panel 10 and the support member 20 and is easy to operate.

[0053] Alternatively, as Figures 1 to 3 、 Figure 5 and Figure 7 As shown, in the embodiment of the present application, the first alignment mark 15 and the second alignment mark 21 are "X"-shaped marks, and the third alignment mark 16 is a "T"-shaped mark.

[0054] Of course, in an optional embodiment, the first alignment mark 15 , the second alignment mark 21 or the third alignment mark 16 may also be set as marks of other shapes, such as an “H” shape or a polygon.

[0055] Alternatively, as Figures 1 to 7As shown, in the embodiment of the present application, the support member 20 includes a first support plate 23 and a second support plate 24 connected to each other, the second alignment mark 21 and the fourth alignment mark 22 are arranged at intervals on the first support plate 23, the first support plate 23 has a first side and a second side relative to each other, the display part 11 is arranged on the first side of the first support plate 23, and the non-display part 13 is arranged on the second side of the first support plate 23; the second support plate 24 has a first side and a second side, the first side of the second support plate 24 is located on the same side as the first side of the first support plate 23, and the second side of the second support plate 24 is located on the same side as the second side of the first support plate 23; along the direction away from the first support plate 23, the distance between the second side surface of the second support plate 24 and the first side surface of the second support plate 24 gradually decreases; the bending portion 12 is arranged in contact with the second support plate 24.

[0056] In the embodiment of the present application, the support member 20 includes a first support plate 23 and a second support plate 24 connected to each other. The display portion 11 is located on a first side of the first support plate 23, and the non-display portion 13 is located on a second side of the first support plate 23. The second alignment mark 21 and the fourth alignment mark 22 are spaced apart on the first support plate 23 to facilitate the third alignment mark 16 provided on the display portion 11 to mate with the fourth alignment mark 22 provided on the first support plate 23. The first side of the second support plate 24 is provided on the same side as the first side of the first support plate 23, and the second side of the second support plate 24 is provided on the same side as the second side of the first support plate 23. In addition, the distance between the second side surface of the second support plate 24 and the first side surface of the second support plate 24 gradually decreases in a direction away from the first support plate 23. The bent portion 12 is provided in contact with the outer wall of the second support plate 24. This arrangement can reduce the impact of the physical seam between the flexible display panel 10 and the support member 20 on the visual effect.

[0057] It should be noted that the direction away from the first support plate 23 refers to the direction from the first support plate 23 to the second support plate 24. The first side surface of the second support plate 24 refers to the side of the second support plate 24 facing the first side of the second support plate 24; the second side surface of the second support plate 24 refers to the side of the second support plate 24 facing the second side of the second support plate 24.

[0058] Alternatively, as Figure 2 、 Figure 4 and Figure 6 As shown, in the embodiment of the present application, the distance between the first side surface of the first support plate 23 and the second side surface of the first support plate 23 gradually decreases along the direction from the first support plate 23 to the second support plate 24. Since the support member 20 and the flexible display panel 10 are arranged in a close relationship, this arrangement can reduce the impact of the physical seam between the flexible display panel 10 and the support member 20 on the visual effect. Optionally, a second alignment mark 21 is provided on the second side of the first support plate 23.

[0059] It should be noted that the first side surface of the first support plate 23 refers to the side of the first support plate 23 facing the first side of the first support plate 23; the second side surface of the first support plate 23 refers to the side of the first support plate 23 facing the second side of the first support plate 23.

[0060] Alternatively, as Figure 2 、 Figure 4 and Figure 6 As shown, in the embodiment of the present application, the first side surface of the first support plate 23 and the first side surface of the second support plate 24 are located in the same horizontal plane, and the inclination angle of the second side surface of the first support plate 23 relative to the horizontal plane is smaller than the inclination angle of the second side surface of the second support plate 24 relative to the horizontal plane. With this arrangement, the side of the support member 20 facing away from the display portion 11 gradually tilts, making it easier to bend the flexible display panel 10 and less prone to damage.

[0061] In the embodiment of the present application, the flexible display device can be applied to a splicing screen module solution with a small bending radius, and can solve the problem in the prior art that the support member is not light-transmissive, which causes the support member to easily block the alignment mark on the flexible display panel, making it impossible to identify and detect the alignment mark, and making it difficult to perform alignment identification and installation through two corresponding alignment marks set on the flexible display panel.

[0062] Based on the same inventive concept, the present invention provides a method for manufacturing a flexible display device. The flowchart of the method is as follows: Figure 8 As shown, the method includes:

[0063] S101. Based on a pre-established model of the support member 20 and the flexible display panel 10, determine first position information of a second alignment mark 21 on the support member 20 corresponding to the first alignment mark 15 provided on the flexible display panel 10; wherein: in the model, the flexible display panel 10 is bent to form a display portion 11, a bending portion 12, and a non-display portion 13 connected in sequence, the display portion 11, the bending portion 12, and the non-display portion 13 form a support cavity, the support member 20 is located in the support cavity and is attached to the display portion 11, the bending portion 12, and the non-display portion 13, and the first alignment mark 15 is provided on the non-display portion 13 (such as Figures 1 to 3 shown);

[0064] S102: Make a second alignment mark 21 (such as Figure 5 shown);

[0065] S103 , using the first alignment mark 15 and the second alignment mark 21 , align and install the flexible display panel 10 and the support member 20 to form the flexible display device 100 .

[0066] In an embodiment of the present application, a model of the support member 20 and the flexible display panel 10 is pre-established. Based on the model, the first position information of the second alignment mark 21 corresponding to the first alignment mark 15 set on the flexible display panel 10 is determined on the support member 20. Then, according to the first position information, the second alignment mark 21 is made on the support member 20. Then, the first alignment mark 15 and the second alignment mark 21 are used to align and install the flexible display panel 10 and the support member 20, thereby forming the flexible display device 100.

[0067] In the embodiment of the present application, the flexible display panel 10 is bent to form a display portion 11, a bent portion 12, and a non-display portion 13, which are connected in sequence. The display portion 11 is used to display an image, and the non-display portion 13 is located on the side of the support member 20 facing away from the display portion 11. The display portion 11, the bent portion 12, and the non-display portion 13 enclose a support cavity, and the support member 20 is located within the support cavity. The support member 20 supports the flexible display panel 10. Moreover, because the support member 20 is arranged in close contact with the display portion 11, the bent portion 12, and the non-display portion 13, there is no gap or a small gap between the support member 20 and the inner wall of the support cavity, thereby reducing the seam between the support member 20 and the flexible display panel 10 and enhancing the visual effect.

[0068] In addition, in the embodiment of the present application, since the non-display portion 13 is provided with a first alignment mark 15 and the support member 20 is provided with a second alignment mark 21 corresponding to the first alignment mark 15, the first alignment mark 15 cooperates with the second alignment mark 21 to achieve the purpose of aligning and installing the flexible display panel 10 and the support member 20; and since the display portion 11, the bending portion 12 and the non-display portion 13 are all fitted with the support member 20, alignment is achieved by cooperating with the first alignment mark 15 and the second alignment mark 21, and the flexible display panel 10 is fitted along the outer wall of the support member 20, so that the flexible display panel 10 can be accurately bent, thereby achieving the flexible display panel 10 being accurately aligned, fitted, bent, and installed on the support member 20.

[0069] Moreover, in the embodiment of the present application, by providing a second alignment mark 21 corresponding to the first alignment mark 15 on the support member 20, and realizing alignment installation through the cooperation of the first alignment mark 15 and the second alignment mark 21, it is possible to solve the problem in the prior art that the support member is not light-transmissive, which causes the support member to easily block the alignment mark on the flexible display panel, making it impossible to identify and detect the alignment mark, and making it difficult to perform alignment identification and installation through the two corresponding alignment marks provided on the flexible display panel.

[0070] Alternatively, as Figure 9 As shown, in the embodiment of the present application, a model of the support member 20 and the flexible display panel 10 is pre-established, including:

[0071] S201, scanning the flexible display panel 10 and the support member 20;

[0072] S202 : Building models of the support member 20 and the flexible display panel 10 according to preset path parameters corresponding to the bending path of the flexible display panel 10 .

[0073] In the embodiment of the present application, the flexible display panel 10 and the support member 20 are scanned to obtain image information of the flexible display panel 10 and the support member 20. The bending path of the flexible display panel 10 is simulated based on preset path parameters corresponding to the bending path of the flexible display panel 10. In this way, a model of the support member 20 and the flexible display panel 10 is established.

[0074] Optionally, in an embodiment of the present application, the bending equipment includes a bending unit, a laser processing unit and an image recognition unit. The bending equipment is used to produce a flexible display device. The bending unit is used to bend the flexible display panel 10, the laser processing unit is used to process the alignment mark, and the image recognition unit is used to obtain images of the flexible display panel 10 and the support member 20 to facilitate modeling of the flexible display panel 10 and the support member 20, and to obtain position information and image information of the alignment mark to facilitate marking and alignment between the alignment marks.

[0075] Conventional bending rules for flexible display panels are 180° arc bends. In spliced ​​screen applications, irregular bending paths are introduced to reduce the bottom frame. Optionally, in the embodiment of the present application, the bending path of the flexible display panel 10 is an irregular bending path. The flexible display panel 10 is placed in contact with the outer wall of the support member 20.

[0076] Optionally, in an embodiment of the present application, the bending unit adopts a reverse bending device.

[0077] Optionally, in the embodiment of the present application, a laser processing process is used to make the second alignment mark 21 on the support member 20.

[0078] Optionally, in an embodiment of the present application, the laser marking position accuracy is within the range of ±10um.

[0079] Optionally, in the embodiment of the present application, the image recognition unit is a camera. Optionally, in the embodiment of the present application, the image recognition unit is a CCD (Charge-coupled Device) camera.

[0080] For a camera to recognize an object, key parameters are camera pixels, resolution, and field of view (FOV). FOV refers to the area the camera actually captures, expressed in millimeters by millimeters. FOV is determined by the number of pixels and resolution. For example, a camera with 1K*1K pixels and a resolution of 20µm (which is larger than 30µm), has a FOV of 1K*20×1k*20 = 20mm×20mm. For a camera with a resolution of 30µm, its FOV is 1K*30×1k*30 = 30mm×30mm. In other words, for the same camera, a higher resolution results in a smaller FOV.

[0081] In the embodiment of the present application, FOV refers to the recognition range of the CCD camera. The CCD camera is used to obtain images of the flexible display panel 10 and the support member 20 to facilitate modeling of the flexible display panel 10 and the support member 20; and is used to identify and determine the specific position on the support member 20 corresponding to the first position information, so as to facilitate the production of the second alignment mark 21 on the support member 20 using a laser processing unit based on the specific position on the support member 20 corresponding to the first position information identified by the CCD camera. At the same time, it can be used to identify the first alignment mark 15 and the third alignment mark 16 on the flexible display panel 10 and the second alignment mark 21 and the fourth alignment mark 22 on the support member 20, so as to facilitate the alignment between the corresponding alignment marks.

[0082] In an embodiment of the present application, within the FOV viewing angle, a CCD camera is used to photograph and scan to capture and identify information such as the pattern and / or outer contour, relative position relationship, etc. of the flexible display panel 10, the first alignment mark 15 and the third alignment mark 16 provided on the flexible display panel 10, and the support member 20, and the fourth alignment mark 22 provided on the support member 20. By simulating the flexible display panel 10, the support member 20 and the bending path of the flexible display panel 10, the coordinate information (such as X-axis coordinate, Y-axis coordinate, Z-axis coordinate) and angle information (such as plane angle, which is the angle at which the second side of the first support plate 23 is inclined relative to the horizontal plane) of the second alignment mark 21 on the support member 20 are calculated. Then, based on the above parameters, the corresponding positions of the above parameters on the support member 20 are determined by photographing and scanning with a CCD camera, and then the second alignment mark 21 is made at the corresponding position on the support member 20 using a laser.

[0083] In the embodiment of the present application, the mark recognition and transfer technology is used to solve the problem that the bending process marks of the flexible splicing screen with small seams cannot be recognized and aligned.

[0084] In actual operation, the bending unit, laser processing unit and image recognition unit all need to be calibrated before use.

[0088] In an embodiment of the present application, by obtaining the orthographic projection of the first alignment mark 15 on the support 20, the position of the second alignment mark 21 on the support 20 can be determined, and by obtaining the coordinate information and angle information of the orthographic projection on the support 20, the first position information can be determined, thereby determining the first position information of the second alignment mark 21 on the support 20.

[0089] An orthographic projection refers to a parallel projection line perpendicular to the projection plane. In the embodiment of the present application, the projection plane is the second side of the first support plate 23 of the support member 20. The parallel projection line is perpendicular to the second side of the first support plate 23. The projection formed by projecting the shape of the first alignment mark 15 onto the second side of the first support plate 23 by this parallel projection line is the orthographic projection of the first alignment mark 15 on the support member 20.

[0090] Alternatively, as Figure 11 As shown, the method for manufacturing the flexible display device according to the embodiment of the present application further includes:

[0091] S401, based on a pre-established model of the support member 20 and the flexible display panel 10, determining second position information of a fourth alignment mark 22 on the support member 20 corresponding to the third alignment mark 16 provided on the display portion 11;

[0093] S403 , aligning and installing the flexible display panel 10 and the support member 20 using the third alignment mark 16 and the fourth alignment mark 22 .

[0094] In an embodiment of the present application, a model of the support member 20 and the flexible display panel 10 is pre-established. Based on the model, the second position information of the fourth alignment mark 22 corresponding to the third alignment mark 16 set on the display part 11 on the support member 20 is determined. Then, according to the second position information, the fourth alignment mark 22 is made on the support member 20. The fourth alignment mark 22 is used to align with the third alignment mark 16. Then, the third alignment mark 16 and the fourth alignment mark 22 are used to align and install the flexible display panel 10 and the support member 20.

[0095] In the embodiment of the present application, the first alignment mark 15 cooperates with the second alignment mark 21, and the third alignment mark 16 cooperates with the fourth alignment mark 22, so as to achieve the purpose of aligning and installing the flexible display panel 10 and the support member 20. This arrangement can improve the alignment accuracy, thereby improving the accuracy of installation.

[0096] Optionally, in an embodiment of the present application, determining the second position information of the fourth alignment mark 22 corresponding to the third alignment mark 16 set on the display unit 11 on the support member 20 includes: obtaining the orthographic projection of the third alignment mark 16 on the support member 20; and then obtaining the coordinate information and angle information of the orthographic projection on the support member 20 to determine the second position information.

[0097] Optionally, in an embodiment of the present application, a fourth alignment mark 22 is formed by making an avoidance hole on the support member 20, wherein the orthographic projection of the avoidance hole on the display unit 11 covers the third alignment mark 16, that is, the orthographic projection of the third alignment mark 16 on the support member 20 is located in the avoidance hole.

[0098] The third alignment mark 16 can be accurately observed through the avoidance hole, which facilitates the alignment of the third alignment mark 16 and the avoidance hole, thereby aligning and installing the flexible display panel 10 and the support member 20; and the operation is simple.

[0099] Alternatively, as Figure 2 、 Figure 4 and Figure 6 As shown, in the embodiment of the present application, the avoidance hole passes through the first support plate 23 .

[0100] Alternatively, as Figures 1 to 3 、 Figure 5 and Figure 7 As shown, in the embodiment of the present application, the first alignment mark 15 and the second alignment mark 21 are "X"-shaped marks, and the third alignment mark 16 is a "T"-shaped mark.

[0101] Of course, in an optional embodiment, the first alignment mark 15 , the second alignment mark 21 or the third alignment mark 16 may also be set as marks of other shapes, such as an “H” shape or a polygon.

[0102] Alternatively, as Figures 1 to 7As shown, in the embodiment of the present application, the support member 20 includes a first support plate 23 and a second support plate 24 connected to each other, the second alignment mark 21 and the fourth alignment mark 22 are arranged at intervals on the first support plate 23, the first support plate 23 has a first side and a second side relative to each other, the display part 11 is arranged on the first side of the first support plate 23, and the non-display part 13 is arranged on the second side of the first support plate 23; the second support plate 24 has a first side and a second side, the first side of the second support plate 24 is located on the same side as the first side of the first support plate 23, and the second side of the second support plate 24 is located on the same side as the second side of the first support plate 23; along the direction away from the first support plate 23, the distance between the second side surface of the second support plate 24 and the first side surface of the second support plate 24 gradually decreases; the bending portion 12 is arranged in contact with the second support plate 24.

[0103] In the embodiment of the present application, the support member 20 includes a first support plate 23 and a second support plate 24 connected to each other. The display portion 11 is located on a first side of the first support plate 23, and the non-display portion 13 is located on a second side of the first support plate 23. The second alignment mark 21 and the fourth alignment mark 22 are spaced apart on the first support plate 23 to facilitate the third alignment mark 16 provided on the display portion 11 to mate with the fourth alignment mark 22 provided on the first support plate 23. The first side of the second support plate 24 is provided on the same side as the first side of the first support plate 23, and the second side of the second support plate 24 is provided on the same side as the second side of the first support plate 23. In addition, the distance between the second side surface of the second support plate 24 and the first side surface of the second support plate 24 gradually decreases in a direction away from the first support plate 23. The bent portion 12 is provided in contact with the outer wall of the second support plate 24. This arrangement can reduce the impact of the physical seam between the flexible display panel 10 and the support member 20 on the visual effect.

[0104] It should be noted that the direction away from the first support plate 23 refers to the direction from the first support plate 23 to the second support plate 24. The first side surface of the second support plate 24 refers to the side of the second support plate 24 facing the first side of the second support plate 24; the second side surface of the second support plate 24 refers to the side of the second support plate 24 facing the second side of the second support plate 24.

[0105] Alternatively, as Figure 2 、 Figure 4 and Figure 6 As shown, in the embodiment of the present application, the distance between the first side surface of the first support plate 23 and the second side surface of the first support plate 23 gradually decreases along the direction from the first support plate 23 to the second support plate 24. Since the support member 20 and the flexible display panel 10 are arranged in a close relationship, this arrangement can reduce the impact of the physical seam between the flexible display panel 10 and the support member 20 on the visual effect. Optionally, a second alignment mark 21 is provided on the second side of the first support plate 23.

[0106] It should be noted that the first side surface of the first support plate 23 refers to the side of the first support plate 23 facing the first side of the first support plate 23; the second side surface of the first support plate 23 refers to the side of the first support plate 23 facing the second side of the first support plate 23.

[0107] Alternatively, as Figure 2 、 Figure 4 and Figure 6 As shown, in the embodiment of the present application, the first side surface of the first support plate 23 and the first side surface of the second support plate 24 are located in the same horizontal plane, and the inclination angle of the second side surface of the first support plate 23 relative to the horizontal plane is smaller than the inclination angle of the second side surface of the second support plate 24 relative to the horizontal plane. With this arrangement, the side of the support member 20 facing away from the display portion 11 gradually tilts, making it easier to bend the flexible display panel 10 and less prone to damage.

[0108] In the embodiment of the present application, the flexible display device can be applied to a splicing screen module solution with a small bending radius, and can solve the problem in the prior art that the support member is not light-transmissive, which causes the support member to easily block the alignment mark on the flexible display panel, making it impossible to identify and detect the alignment mark, and making it difficult to perform alignment identification and installation through two corresponding alignment marks set on the flexible display panel.

[0109] In the embodiment of the present application, the bending process is realized by identifying and comparing the alignment marks on the flexible display panel and the support member, which meets the requirements of subsequent process accuracy evaluation tests.

[0110] Based on the same inventive concept, an embodiment of the present application provides a computer-readable storage medium, which stores a computer program. When the computer program is executed by an electronic device or a processor, various optional implementation methods of the manufacturing method of the flexible display device provided in the embodiment of the present application are implemented.

[0111] The present application provides a computer-readable storage medium applicable to various optional implementations of the manufacturing method of any of the above-mentioned flexible display devices, which will not be described in detail here.

[0112] By applying the embodiments of the present application, at least the following beneficial effects can be achieved:

[0113] 1. In the embodiments of the present application, a flexible display panel includes a display portion, a folding portion, and a non-display portion.

The non-display portion is located on the side of a support member facing away from the display portion. The display portion, the folding portion, and the non-display portion define a support cavity. A support member is located within the support cavity. The support member supports the flexible display panel. Furthermore, because the support member is positioned in contact with the display portion, the folding portion, and the non-display portion, there is no gap, or a very small gap, between the support member and the inner wall of the support cavity. This minimizes the seam between the support member and the flexible display panel, enhancing the visual effect.

[0114] 2. In the embodiment of the present application, since the non-display portion is provided with a first alignment mark and the support member is provided with a second alignment mark corresponding to the first alignment mark, the purpose of aligning and installing the flexible display panel and the support member can be achieved by coordinating the first alignment mark with the second alignment mark; and since the display portion, the bending portion and the non-display portion are all fitted with the support member, alignment is achieved by coordinating the first alignment mark with the second alignment mark, and the flexible display panel is fitted along the outer wall of the support member, so that the flexible display panel can be accurately bent, thereby enabling the flexible display panel to be accurately aligned, fitted, bent, and installed on the support member.

[0115] 3. In the embodiment of the present application, a second alignment mark corresponding to the first alignment mark is provided on the support member, and the alignment installation is achieved through the cooperation of the first alignment mark and the second alignment mark. This can solve the problem in the prior art that the support member is not light-transmissive, which causes the support member to easily block the alignment mark on the flexible display panel, making it impossible to identify and detect the alignment mark, and making it difficult to perform alignment identification and installation through the two corresponding alignment marks provided on the flexible display panel.

[0116] 4. In this embodiment of the present application, the display portion is provided with a third alignment mark, and the support member is provided with a fourth alignment mark corresponding to the third alignment mark.

This arrangement can improve alignment accuracy, thereby improving installation accuracy.
