[0049] The specific embodiments of the present application have been shown in the above-described drawings, and will be described in more detail hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be described in more detail below with reference to the drawings.

[0051] Figure 1 is a structure diagram of a display device, which can include a display panel 11, a middle frame 12 and a control component 13, etc. The display panel 11 can be used to display images, the middle frame 12 is connected with the display panel 11 and can be used to carry the display panel 11, and the control component 13 is electrically connected with the display panel 11 and is used to control the display panel 11 to display images. In addition, the display device further includes a transparent cover plate 14 covering the display panel 11, and in order to show the display panel 11, Figure 1 The transparent cover plate 14 is not shown in the middle frame. Figure 2 is Figure 1 is a cross-sectional structure diagram of the display device shown in FIG. 1. The cross-sectional position is at A-A.

[0052] Please refer to Figure 1 and Figure 2 , wherein the display panel 11 is a flat display panel, the display panel 11 has a display area 111 and a peripheral area 112 located at the periphery of the display area 111, the display area 111 can refer to an area on the display panel 11 having an image display function, and the peripheral area 112 is an area without image display, and some wiring and circuit structures can be arranged in the peripheral area.

[0053] Figure 1 In the display device shown, due to the existence of the peripheral area 112, the distance d between the edge of the actual image display area 111 (when the display panel is a flat display panel, the actual image display area can be the display area of the display panel, that is, the display area of the display panel in the display device, and in the display device shown, the actual image display area is the display area 11 of the display panel) and the edge of the front face of the display device (the front face of the display device can refer to the face of the display device on which the image is displayed) is large, thereby resulting in a low screen-to-body ratio of the display device and a poor user experience. Figure 1

[0054] The screen-to-body ratio can refer to the ratio between the area of the actual image display area in the front face of the display device and the total area of the front face.

[0055] Figure 3 FIG. 1 is a structural schematic diagram of a display device (and an exploded structural schematic diagram of a first face m1 and a second face m2) provided by an embodiment of the present application, the display device comprising a display panel 20.

[0056] The display panel 20 comprises a first flat portion 21, at least one bending portion 22, and at least one second flat portion 23. The at least one bending portion 22 is located on at least one side of the first flat portion 21 and is connected to the first flat portion 21 respectively. The second flat portion 23 is connected to the side of the bending portion 22 away from the first flat portion 21. The included angle j between the second flat portion 23 and the first flat portion 21 is less than 90 degrees.

[0057] The display panel 20 comprises a first face m1 and a second face m2. The first face m1 and the second face m2 are oppositely arranged. The first face m1 has a display area q1 and a peripheral area q2 located outside the display area q1. The area of the first flat portion 21 on the first face m1 overlaps the display area q1. The connection position u of the bending portion 22 and the first flat portion 21 is at least partially located in the display area q1. The bending portion 22 is bent towards the second face m2.

[0058] The display panel 20 can be a flexible display panel (for example, an organic light-emitting diode (OLED) display panel). The first flat portion 21 and the bending portion 22 can refer to different parts of the display panel 20. The first flat portion 21 can be a flat and unbent part of the display panel 20. The bending portion 22 can refer to a part of the display panel 20 where bending exists.

[0059] ​In this embodiment, a portion of the display area q1 is located on the first flat portion 21, and a portion of the display area q1 at the edge is located on the bending portion 22. Under this structure, the peripheral area q2 outside the display area q1 located on the bending portion will be on a different plane from the display area located on the first flat portion 21. Therefore, when viewing the display panel from the front, it is difficult to see the peripheral area q2, and thus the peripheral area q2 will not affect the width of the frame of the display device.

[0060] In summary, the display device provided in this application provides a bent portion on at least one side of the flat portion of the display panel, and the connection between the bent portion and the flat portion is at least partially located in the display area of ​​the display panel. That is, the peripheral area and a portion of the display area are bent. This allows the peripheral area outside the display area to be located in the bent portion, reducing the impact of the peripheral area on the width of the display device's bezel, thereby improving the screen-to-body ratio of the display device.

[0061] It should be noted that, by Figure 3 It can be seen that, due to the presence of the bending portion 22, both the first surface m1 and the second surface m2 can be curved surfaces. Furthermore, Figure 3 The diagram shows the structure where the bent portion 22 is located on both sides of the first flat portion 21, but this embodiment does not limit this. The bent portion 22 may also be located on only one side of the first flat portion 21, or it may be located on more sides of the first flat portion 21. This embodiment does not limit this.

[0062] Furthermore, the display panel involved in the embodiments of this application can generally be plate-shaped, and the plate-shaped display panel can be formed by two larger surfaces (a first surface and a second surface) and a side surface connected to these two larger surfaces. In the embodiments of this application, a certain side of a structure (at least one side of the first flat portion) can refer to a side of the structure in a direction parallel to the surface of the first flat portion located on the front of the display device and away from the center of the first surface. For example, please refer to... Figure 4 , Figure 4 yes Figure 3 The diagram shows a top view of the display device. The display panel 20 is approximately rectangular. Therefore, one side of the first flat portion 21 can refer to its upper, left, right, or lower side. Please refer to... Figure 5 , Figure 5 yes Figure 4 The diagram shows a cross-sectional view of the display device at point BB. The second flattening portion 23 is connected to the side of the bending portion 22 away from the first flattening portion 21, and the included angle j between the second flattening portion 23 and the first flattening portion 21 is less than 90 degrees.

[0063] The second flat portion 23 can be a part folded to the second surface m2 of the display panel along with the bending portion 22, and the part itself can be flat. The peripheral area outside the display area can be located on the second flat portion 23. The included angle j between the second flat portion 23 and the first flat portion 21 is less than 90 degrees, which can reduce the influence of the peripheral area that cannot display images on the width of the frame of the display device, improve the screen-to-body ratio of the display device, and further improve the user experience.

[0064] Figure 6 FIG. 6 is a structural schematic diagram of another display device provided by an embodiment of the present application, which is based on the display device shown in FIG. 1 and has some adjustments. Figure 4 The display device includes a control assembly 30 connected with the first side c1 of the first flat portion 21, and at least one bending portion 22 is located on at least one side of the first flat portion 21 except the first side c1.

[0065] Since the first side c1 of the display panel 20 is connected with the control assembly 30, in an exemplary embodiment, the first side c1 of the display panel 20 can not be provided with the bending portion 22, and at least one side of the display panel 20 can be provided with the bending portion 22. In this case, the first side c1 can be connected with the control assembly 30 by using some technologies, for example, the display panel 20 can be connected with the control assembly 30 by using a Chip On Film (COF) technology.

[0066] Of course, the first side c1 of the display panel 20 connected with the control assembly 30 can also be provided with the bending portion 22 involved in the embodiments of the present application, that is, at least one side of the first flat portion 21 of the display panel including the first side c1 can be provided with the bending portion 22, which is not limited in the embodiments of the present application.

[0067] Figure 6 The display panel 20 shown in FIG. 1 is rectangular, and in this structure, the bending portion 21 can be located on two sides adjacent to the first side c1 to reduce the width of the frame on the left and right sides. Figure 6 FIG. 2 shows a structure in which the second side c2 opposite to the first side c1 is not provided with the bending portion 22. The second side c2 can be provided with some relatively complex lines or structures, and thus the bending portion is not provided on the second side c2 to reduce the manufacturing difficulty of the display device.

[0068] Of course, the second side c2 opposite to the first side c1 can also be provided with the bending portion 22, which is not limited in the embodiments of the present application. Alternatively, in an exemplary embodiment, as shown in FIG. 3, Figure 7 Figure 7 FIG. 4 is a structural schematic diagram of another display device provided by an embodiment of the present application. In Figure 7 ​In the embodiment, only the second side c2 is provided with the bending part 22, and the first side c1 and the two sides adjacent to the first side c1 are not provided with the bending part 22. In this way, the frame size of the top part can be reduced.

[0069] It should be noted that, in the display device provided in the embodiment of the present application, the first flat part 21 of the display panel 20 includes two adjacent sides, and the bending part 22 is located at one of the two adjacent sides. That is, the bending part 22 can not be located at the two adjacent sides of the first flat part 21 at the same time.

[0070] When the two adjacent edges of the display panel are bent at the same time, the adjacent edges can affect each other or collide, thereby increasing the manufacturing difficulty of the display device. In the embodiment of the present application, the bending part is not located at the two adjacent sides of the first flat part at the same time, thereby reducing the manufacturing difficulty of the display device and reducing the manufacturing cost.

[0071] Of course, in the display device provided in the embodiment of the present application, the bending part can also be arranged at the two adjacent sides of the first flat part, which is not limited in the embodiment of the present application.

[0072] In addition, the display device provided in the embodiment of the present application can further include a light-transmitting cover plate 40 located on the first surface m1 of the display panel 20. The cover plate can be used to protect the display panel 20.

[0073] It should be noted that, in order to clearly show the display panel, Figure 6 In the embodiment, the cover plate 40 is not shown, but this is not limited.

[0074] In an exemplary embodiment, please refer to Figure 8 , Figure 8 is Figure 6 a cross-sectional structure schematic diagram of the display device shown in FIG. 1.

[0075] The second flat part 23 can be parallel to the first flat part 21, that is, the included angle between the second flat part 23 and the first flat part 21 is zero. In this way, the influence of the peripheral area of the second flat part 23 on the frame of the display device can be further reduced.

[0076] In an exemplary embodiment, the display device further includes a back structure 50 located on the second surface m2 of the display panel 20. The back structure can include various structures such as some circuits or support structures.

[0077] The second flat part 23 is attached to the side of the back structure 50 away from the first flat part 21. For example, the side of the back structure 50 away from the first flat part 21 can be provided with super clean foam (SCF), and the second flat part 23 can be attached to the super clean foam.

[0078] The structure that the second flat portion 23 is attached to the back structure 50 can play a fixing role on the second flat portion 23 and the bending portion 22, avoiding the second flat portion 23 and the bending portion 22 from shaking or deforming during the use of the display device, which on one hand reduces the risk of damage of the second flat portion 23 and the bending portion 22 colliding with other structures, and on the other hand avoids the risk of damage of other structures caused by the second flat portion 23 and the bending portion 22 colliding with other structures.

[0079] In an exemplary embodiment, referring to Figure 9 and Figure 10 , Figure 9 is another structural schematic diagram of a display device provided in the embodiments of the present application. Figure 10 is Figure 9 is a sectional structural schematic diagram of the display device shown in FIG. 1 (the sectional position is D-D). The display device includes a middle frame 60 and a light-transmitting cover plate 40. The middle frame is located outside the display panel 20, for example, the middle frame can surround the display panel 20, and the middle frame 60 can be used to protect and mount the display panel 20. It should be noted that, in order to clearly show the display panel, Figure 9 The cover plate 40 is not shown in the middle, but this is not limited.

[0080] The cover plate 40 is located on the first surface m1 of the display panel 20, and the edge of the cover plate 40 is bonded with the middle frame 60. In this way, the sealing performance of the display device can be improved. For example, the sealant 70 can be arranged between the edge of the cover plate 40 and the middle frame 60, and the sealant 70 can be bonded with the edge of the cover plate 40 and the middle frame 60. In addition, the display device can further include an optical adhesive (Optically Clear Adhesive, OCA) 41, and the optical adhesive 41 can bond the cover plate 40 and the display panel 20. In this structure, the middle frame 60, the cover plate 40 and the display panel 20 are connected as a whole by bonding, and thus the middle frame 60 can realize the functions of bearing and fixing the display panel 20. The thickness of the optical adhesive 41 can be 0.075 millimeters. The cover plate 40 can be a 2.5D cover plate, that is, the edge of the cover plate 40 away from the display panel 20 can have a certain curvature.

[0081] The edge of the cover plate 40 in the embodiments of the present application can not be coated with ink to avoid the influence of the ink on the frame of the display device.

[0082] In an exemplary embodiment, the minimum distance s between the orthographic projection of the bending portion 22 on the cover plate 40 and the edge of the cover plate 40 is greater than or equal to the absolute value of the bonding tolerance of the cover plate and the display panel 20. The bonding tolerance is reserved to avoid the edge of the display panel protruding from the cover plate 40.

[0083] In Figure 10 With the structure shown in the figure, the edge of the cover plate 40 can be substantially flush with the actual edge of the display panel 20 (the edge of the orthographic projection of the bending portion 22 on the cover plate 40), so that the gap between the display panel 20 and the middle frame 60 can be reduced, and the influence of the gap on the frame width of the display device can be reduced. For example, the minimum distance s between the orthographic projection of the bending portion 22 on the cover plate 40 and the edge of the cover plate 40 is greater than or equal to the absolute value of the bonding tolerance of the cover plate and the display panel 20. For example, the bonding tolerance can be ±0.25 mm.

[0084] In an exemplary embodiment, the middle frame 60 can include a support plate 62 and a retaining wall 61. The support plate 62 can be located on the side of the display panel 20 away from the cover plate 40, and the retaining wall 61 can be erected on the support plate 62 and located on the side of the bending portion 22 away from the first flat portion 21. The edge of the cover plate 40 can be bonded to the end of the retaining wall 61 away from the support plate 62. The support plate 62 and the retaining wall 61 can be an integral structure, and the cross section of the support plate 62 and the retaining wall 61 at the position shown in the figure can form an "L" shaped structure. Figure 10

[0085] In an exemplary embodiment, the side of the second flat portion 23 away from the first flat portion 21 can be in contact with or bonded to the support plate 62 of the middle frame 60. In this structure, the support plate 62 of the middle frame 60 can be used to support the display panel 20. In this structure, since the support plate 62 can achieve the function of supporting or fixing the display panel 20, the edge of the cover plate 40 can not be bonded to the middle frame 60 (of course, in this structure, the edge of the cover plate 40 can also be bonded to the middle frame 60, and the embodiments of the present application do not limit this).

[0086] In an exemplary embodiment, please refer to Figure 11 , Figure 11 is Figure 9 another cross-sectional structure diagram of the display device shown in the figure (the cross-sectional position is E-E). The middle frame 60 has a recess k on it, and the recess k is located on the area of the middle frame 60 opposite to the bending portion 22. The recess k can be used to avoid the bending portion 22 of the display panel 20, so as to increase the distance between the middle frame 60 and the bending portion 22, reduce the risk of collision between the display panel 20 and the middle frame 60, and improve the protection effect on the display panel 20. In addition, due to the existence of the recess k, the distance between the display panel 20 and the middle frame can be closer, so as to reduce the influence of the gap between the display panel 20 and the middle frame 60 on the frame width of the display device, and improve the screen-to-body ratio of the display device.

[0087] ​Optionally, when the middle frame 60 comprises the support plate 62 and the retaining wall 61 standing on the support plate 62, the recess k can be located on the retaining wall 61.

[0088] In an exemplary embodiment, the recess k comprises a curved surface recessed away from the bending portion 22. Since the side of the bending portion 22 facing the middle frame 60 is generally a curved surface, the recess k can comprise a curved surface recessed away from the bending portion 22, which can be approximately shaped with the bending portion 22, and when the display panel 20 collides with the middle frame 60 due to shaking of the display device, the contact area of the bending portion 22 and the recess k can be increased to improve the protection of the display panel.

[0089] In addition, the recess can also have other shapes, for example, a trapezoidal recess, which is not limited in the embodiments of the present application.

[0090] It should be noted that, as shown in Figure 2 , in the related art display device, the flat display panel 11 and the cover plate 14 are tightly attached together, and thus the end of the display panel 11 close to the middle frame 12 is also close to the end of the cover plate 14 in the thickness direction of the display device, and in this structure, it is difficult to set a recess on the middle frame 12 corresponding to the end of the display panel 11 to avoid the display panel 11. In the display device provided by the embodiments of the present application, as shown in Figure 11 , since the display panel 20 has the bending portion 22, the bending portion 22 will move the end of the display panel close to the middle frame away from the cover plate 40 by a distance, which increases the distance between the end of the display panel 20 and the end of the cover plate 40 in the thickness direction of the display device, and thus it is convenient to set a recess k on the middle frame 60 opposite to the bending portion 22 to avoid the display panel.

[0091] In the above embodiments, a plurality of cross-sectional views of display devices are provided, and the structures of the edges of the display devices (the bending portions of the edges and the structures of the middle frames) are shown in the cross-sectional views. The structure of each edge of the display device provided by the embodiments of the present application can comprise at least one of the above-mentioned structures.

[0092] Please refer to Figure 12 , Figure 12is a structural schematic diagram of a display panel in a display device provided by an embodiment of the present application. The display panel includes a display structure layer p2, and a back plate p3 and a polaroid p1 located on two sides of the display structure layer p2. The display structure layer p2 can include a plurality of light emitting units for displaying images. The back plate p3 can be made of a flexible material and used to carry the display structure layer p2. The polaroid p1 is used to improve the display effect of the display structure layer p2, for example, can be used to reduce reflection and the like. Of course, the film layer structure in the display panel provided by the embodiment of the present application can also be other structures. For example, reference can be made to other organic light emitting diode display panels, which are not limited by the embodiment of the present application. In the embodiment of the present application, the thicknesses of the back plate p3 and the polaroid p1 applied can be relatively thin. For example, the thickness of the back plate p3 can be 0.068 millimeters, and the thickness of the polaroid p1 can be 0.046 millimeters. In this way, the overall thickness of the display panel can be reduced, and the bending difficulty of the display panel can be reduced.

[0093] The display device provided by the embodiment of the present application can bend the edge of the display panel during manufacturing, as shown in Figure 13 Figure 13 is a structural schematic diagram of a display device during manufacturing provided by the embodiment of the present application. The second flat portion 23 can be folded along the direction of the arrow t by applying pressure to the edge of the display panel 20 through the sliding block 80. When the second flat portion 23 is folded to the position adhered to the back structure 50, the sliding block 80 can continuously apply pressure to the second flat portion 23 for a period of time to avoid the second flat portion 23 and the bending portion 22 from rebounding or warping.

[0094] In summary, the display device provided by the embodiment of the present application can set the bending portion on at least one side of the flat portion of the display panel, and the connection between the bending portion and the flat portion is at least partially located in the display area of the display panel, that is, the peripheral area and a part of the display area are bent. In this way, the peripheral area outside the display area is located in the bending portion, which reduces the influence of the peripheral area on the width of the frame of the display device, and further improves the screen-to-body ratio of the display device.

[0095] Figure 14 is a method flowchart of a control method of a display device provided by an embodiment of the present application. The method is used for any one of the display devices provided by the above embodiments, and includes the following steps:

[0096] Step 301, acquiring image data.

[0097] ​The display device control method provided by the embodiments of the present application can be applied to a control component of a display device, which can obtain image data from an external data source (which can include a wired data source and a wireless data source, and the embodiments of the present application do not limit this) or can also generate image data locally.

[0098] In step 302, based on the image data, an image is displayed in a target region in the display region, and the target region is a normal projection region of a target plane on the display region, and the target plane is a plane parallel to the first flat portion and located on a side of the first flat portion away from the second flat portion.

[0099] Since the display device provided by the embodiments of the present application has a bending portion at the edge of the display panel, and thus a part of the display region of the display panel can not be located on the front of the display device, the display panel control method provided by the embodiments of the present application can display an image in the part of the display region located on the front of the display device by controlling the display region.

[0100] Please refer to Figure 15 , Figure 15 is a structural schematic diagram of a display device provided by the embodiments of the present application. The target plane m3 can be a plane parallel to the first flat portion 21 and located on a side of the first flat portion 21 away from the second flat portion 23, where parallel to the first flat portion 21 can mean parallel to the surface of the first flat portion 21 on the first surface m1, and located on a side of the first flat portion 21 away from the second flat portion 23 can mean located on a side of the front of the display panel 20. Correspondingly, the target region q4 is the normal projection region of the target plane m3 on the display region q1. The display region q1 Figure 13 on the target plane m3 (i.e., the target region q4) can be considered as the region of the display panel facing the front of the display device, which is the region that can be actually viewed by the user, and thus the method provided by the embodiments of the present application can display an image in the target region q4. Specifically, the opening and closing of each light emitting unit in the display panel can be controlled to accurately control the region in the display region of the display panel that actually displays an image, so that the region that actually displays an image is the normal projection region q4.

[0101] For example, the resolution of the display panel is 1920*1080, that is, the pixels (each pixel can be composed of at least one light emitting unit (such as three or four)) in the display panel are arranged as 1920 columns and 1080 rows. If the display panel is rectangular, the bending part is located at two sides adjacent to the first side connected with the control assembly, and each of the two sides has 20 columns of pixels bent to the back of the display panel. The projection area of the target plane m3 on the first plane m1 does not include the 40 columns of pixels, and then the 40 columns of pixels can be displayed by being turned off, that is, only the 21st column to the 1900th column of pixels located in the center are started. When the bending part is located at other positions, the pixels can also be started and turned off by referring to the example, and the embodiments of the present application do not limit this.

[0102] Since the edge of the target area q4 is the edge of the front surface of the display panel, when the display panel displays, the peripheral area of the image that cannot be displayed will not be exposed on the front surface of the display device, and thus will not affect the width of the frame of the display device, and a narrow-frame display device is realized.

[0103] In summary, the control method of the display device provided by the embodiments of the present application can accurately control the area of the display panel that actually displays the image, so that the area is the area facing the front surface of the display device. In this way, the peripheral area can be avoided to affect the frame of the display device, and thus the screen-to-body ratio of the display device can be improved.
