[0051] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0053] One type of display device in the related technology can expand or roll up the flexible display panel to one side of the display device by sliding the flexible display panel, thereby increasing or decreasing the size of the flexible display panel in the sliding direction and realizing the size adjustment function of the display surface of the display device.

[0054] The aforementioned display device includes a housing, a scroll, and a flexible display panel. During sliding, the flexible display panel, located inside the housing, can be moved to the side of the display surface of the device via a rotating shaft, thereby increasing the size of the display surface. In other words, the flexible display panel can be extended and retracted through sliding.

[0055] However, after being bent for a long time, flexible display panels will exhibit creep, resulting in internal stress at the bent locations. This causes some areas of the flexible display panel to arch or become uneven after being unfolded, leading to poor display performance.

[0056] This application provides a display panel and a display device that can solve the problems existing in the related technologies.

[0057] Figure 1 This is a schematic diagram of the structure of a display device provided in an embodiment of this application. Figure 2 This is a schematic diagram of another display device provided in an embodiment of this application. Please refer to it. Figure 1 and Figure 2 The display device 10 may include: a first housing 101, a second housing 102, a scroll 103, a flexible display panel 104, and a sliding bracket 105.

[0058] The first housing 101 can be slidably connected to the second housing 102. During the unfolding of the display device, the second housing 102 can slide away from the first housing 101, and during the retraction of the display device, the second housing 102 can slide towards the first housing 101.

[0059] The spool 103 can be located in the second housing 102. The spool 103 can include a shaft core and at least two spools 1031. The shaft core and the second housing 102 are fixedly connected. The at least two spools 1031 are arranged along a first direction f1 and sleeved on the shaft core. The first direction f1 is the length direction of the shaft core, and the rotation direction of the spool 103 is the first direction f1.

[0060] The flexible display panel 104 may include a first portion 1041 and a second portion 1042. The first portion 1041 of the flexible display panel 104 is fixedly connected to the first housing 101, and the second portion 1042 of the flexible display panel 104 is wound around a reel 103. One side of the first portion 1041 of the flexible display panel 104 is connected to one side of the second portion 1042 of the flexible display panel 104.

[0061] like Figure 1 As shown, Figure 1A schematic diagram of a display device 10 in its unfolded state is shown. When the second housing 102 slides a certain distance relative to the first housing 101 along a second direction f2, the second portion 1042 of the flexible display panel 104 can slide out from the inside of the second housing 102, thereby increasing the display surface size of the display device 10. The second direction f2 is the direction of relative movement between the first housing 101 and the second housing 102. When the display device 10 is in its unfolded state, the display surfaces of the first portion 1041 and the second portion 1042 are located on the same plane.

[0062] Figure 2 To facilitate the illustration of the internal structure of the display device 10, Figure 2 A schematic diagram of a display device in its unfolded state without a flexible display panel 104 is shown. A sliding bracket 105 may be located in a second housing 102, and the sliding bracket 105 may be used to support a second portion 1042 of the flexible display panel 104. The sliding bracket 105 may include a first connector 1051 and at least two suction portions 1052. The first connector 1051 is located on the side of the scroll 103 near the first housing 101 and is fixedly connected to the second housing 102. The first connector 1051 may be rod-shaped, and its length direction may be a first direction f1. Both ends of the first connector 1051 may be bolted to the second housing 102.

[0063] The adsorption part 1052 can be fixedly connected to the side of the first connector 1051 near the scroll 103, and the adsorption part 1052 can overlap with the core in the thickness direction of the display device 10. That is, the adsorption part 1052 can be sleeved on the core, or the adsorption part 1052 can cover at least part of the core in the thickness direction of the display device 10.

[0064] The adsorption part 1052 can be arranged alternately with the roll 1031 in the first direction f1. The adsorption part 1052 has an adsorption surface p1 on the side of the plane where the display surface of the first part 1041 of the flexible display panel 104 is located. The adsorption surface p1 is used to adsorb the second part 1042 of the flexible display panel 104.

[0065] Because the second part 1042 of the flexible display panel 104 near the roller 103 has a large internal stress, the second part 1042 of the flexible display panel 104 can be adsorbed by the adsorption surface p1 of the adsorption part 1052, so that the second part 1042 of the flexible display panel 104 is relatively flat near the roller 103, thereby making the display surface of the second part 1042 of the flexible display panel 104 and the display surface of the second part 1042 of the flexible display panel 104 lie in the same plane.

[0066] In summary, this application provides a display panel comprising: a first housing, a second housing, a scroll, a flexible display panel, and a sliding bracket. The sliding bracket has adsorption portions arranged alternately with the scroll's roll in a first direction. The adsorption surfaces of these adsorption portions can adsorb onto a second portion of the flexible display panel. Thus, the adsorption force between the adsorption portions and the display panel reduces the impact of internal stress on the flexible display panel at the scroll, solving the problem of unevenness in certain areas of the display panel in related technologies, and improving the display effect of the display panel.

[0067] Optionally, such as Figure 3 As shown, Figure 3 yes Figure 2 The diagram shows a cross-sectional view of the adsorption section along the A1-A2 position in the display device. The adsorption section 1052 may include a receiving member 10521 and an adsorption member 10522. The receiving member 10521 can be fixedly connected to the first connecting member 1051, and the receiving member 10521 has a first groove c1 on the side of the plane where the display surface of the first part 1041 of the flexible display panel 104 is located. The adsorption member 10522 is located in the first groove c1. In this way, the adsorption section 1052 can have an adsorption force with the second part 1042 of the flexible display panel 104, facing the side of the plane where the display surface of the first part 1041 of the flexible display panel 104 is located. The orientation of the adsorption part with adsorption force on the adsorption section 1052 can be controlled more accurately, which can avoid the area of ​​the adsorption surface p1 on the adsorption section 1052 being too large, resulting in excessive adsorption force between the adsorption section 1052 and the flexible display panel 104, and can also avoid excessive friction between the adsorption section 1052 and the flexible display panel 104.

[0068] Optionally, such as Figure 3 As shown, the depth h1 of the first groove c1 of the receiving member 10521 is greater than the dimension h2 of the adsorption member 10522 in the direction perpendicular to the bottom of the first groove c1. This achieves two effects: firstly, it prevents the adsorption member 10522 from protruding from the receiving member 10521, thus preventing it from damaging the flexible display panel 104; secondly, by adjusting the dimension h2 of the adsorption member 10522 in the direction perpendicular to the bottom of the first groove c1, the distance between the adsorption member 10522 and the flexible display panel 104 can be adjusted, thereby adjusting the magnitude of the adsorption force between them.

[0069] like Figure 4 As shown, Figure 4This is a schematic diagram of a display panel structure provided in an embodiment of this application. The flexible display panel 104, while possessing flexibility, also has certain supporting properties, enabling it to bend and roll. The flexible display panel 104 may include a flexible display substrate and multiple strip-shaped support bars 1044 located on the side of the flexible display substrate facing away from the display surface. The length direction of the multiple strip-shaped support bars 1044 is parallel to the first direction f1, meaning the support bars 1044 can support the flexible display substrate 104. Since the first portion 1041 of the flexible display panel 104 does not need to roll, the multiple support bars 1044 can all be located in the area where the second portion 1042 of the flexible display panel 104 is located. There is a certain distance between the multiple support bars 1044, allowing the second portion 1042 of the flexible display panel 104 to bend in the arrangement direction of the multiple support bars 1044.

[0070] The material of the support strip 1044 may include stainless steel. For example, the material of the support strip 1044 may be SUS stainless steel. The adsorption member 10522 and the support strip 1044 can be magnetically attracted to each other, thereby enabling the adsorption part 1052 and the flexible display panel 104 to have an adsorption force.

[0071] Optionally, such as Figure 3 As shown, the first groove c1 includes a plurality of sub-grooves c11 arranged along the first direction f1, and the adsorption member 10522 includes a plurality of magnets, which are respectively located in the plurality of sub-grooves c11. The plurality of sub-grooves c11 can make the magnetic adsorption force of the adsorption member 10522 on the support strip 1044 more uniform.

[0072] like Figure 5 As shown, Figure 5 This is a schematic diagram of a receiving member having a first groove. When the first groove c1 of the receiving member 10521 has a groove, the adsorption member 10522 may include a magnet. Thus, the magnetic adsorption force of the adsorption member 10522 on the support strip 1044 is more concentrated, resulting in a greater degree of bending deformation of the support strip 1044.

[0073] In the embodiments of this application Figure 3 In the adsorption component 10522 shown, by providing multiple grooves c11, the probability of the support strip 1044 bending and deforming can be reduced.

[0074] Optionally, such as Figure 3As shown, the dimension d1 of the sub-groove c11 in the first direction f1 ranges from 1 mm to 10 mm. Within this range, the dimension of the sub-groove c11 is relatively small, and the sidewalls around the sub-groove c11 can provide good support for the support bar 1044, preventing the support bar 1044 from bending and deforming towards the bottom surface of the sub-groove c11.

[0075] Optionally, such as Figure 3 As shown, the receiving member 10521 has a first plane p2 on the side of the plane facing the display surface of the first portion 1041. The opening of the first groove c1 is located in the first plane p2, and the first plane p2 is parallel to the display surface of the first portion 1041. In this way, the surface of the flexible display panel 104 that contacts the adsorption part 1052 can be a plane, which makes the display surface of the flexible display panel 104 relatively flat.

[0076] Optionally, such as Figure 6 As shown, Figure 6 This is a schematic diagram illustrating the positional structure of a scroll and a first plane of a receiving member according to an embodiment of this application. The distance between the scroll 1031 and the plane containing the display surface p3 of the first portion 1041 in the thickness direction f3 of the display device 10 is greater than the distance between the first plane p2 of the receiving member 10521 and the plane containing the display surface p3 of the first portion 1041 of the flexible display panel 104 in the thickness direction f3 of the display device 10. The first plane p2 of the receiving member 10521 can be parallel to the plane containing the display surface p3 of the first portion 1041 of the flexible display panel 104, and the distance between the first plane p2 of the receiving member 10521 and the display surface p3 of the first portion 1041 of the flexible display panel 104 can be the thickness of the flexible display panel 104. That is, the angle e between the tangent line at the starting point a1 where the flexible display panel 104 and the scroll 103 are attached and the plane containing the display surface p3 of the first portion 1041 of the flexible display panel 104 can be greater than 0 degrees and less than 90 degrees. In other words, the highest point of the scroll 103 in the thickness direction f2 of the display device 10 is lower than the highest point of the first plane p2 of the receiving member 10521 in the thickness direction f2 of the display device 10. Thus, the flexible display panel 104 bends at a larger angle at the scroll 103, which reduces the friction between the flexible display panel 104 and the scroll 103, resulting in less tension on the flexible display panel 104 during bending and making it easier for the flexible display panel 104 to slide. It also avoids damage to the flexible display panel 104 due to excessive friction.

[0077] like Figure 2As shown, the receiving member 10521 also has a first curved surface p4 connected to the first plane p2. The first curved surface p4 can improve the smoothness of the sliding of the flexible display panel 104 during the rolling process, so that the flexible display panel 104 can be smoothly transferred from the first plane p2 and the first curved surface p4 of the receiving member 10521 to the roll 103.

[0078] Optionally, such as Figure 7 , Figure 8 and Figure 9 As shown, Figure 7 This is a schematic diagram of another display device provided in an embodiment of this application. Figure 8 yes Figure 7 The diagram shown is a partial structural schematic of the display device. Figure 9 yes Figure 8 The diagram shows a cross-sectional view of a portion of the display device along the B1-B2 position. Figure 7 The display device 10 shown can be Figure 2 The diagram shows a partial structural view of the back of the display device 10. The display device 10 may also include a fixed track 106, a movable track 107, and a slider 108. The fixed track 106 may be located in the first housing 101 and fixedly connected to the first housing 101, and the slider 108 is fixedly connected to the sliding bracket 105.

[0079] The fixed track 106 may have a strip-shaped second groove c2, the length direction of which is parallel to the second direction f2, which is perpendicular to the first direction f1. The movable track 107 is fitted into the second groove c2 so that the movable track 107 can slide in the second direction f2. The shape of the second groove c2 may be a double "C" shape with opposite openings.

[0080] The moving track 107 may have a strip-shaped third groove c3, the length direction of which is parallel to the second direction f2. A slider 108 is fitted into the third groove c3 so that the slider 108 can drive the sliding bracket 105 to slide in the second direction f2. The shape of the third groove c3 may be "C". The material of the moving track 107 may include a self-lubricating material; for example, the material of the moving track 107 may be polyoxymethylene (POM).

[0081] like Figure 8As shown, slider 108 is slidably located within the third groove c3, and slider 108 can be T-shaped. Slider 108 may include a fixedly connected inset portion 1081 and a protrusion 1082. The inset portion 1081 is located inside the third groove c3, and the protrusion 1082 extends from the opening of the third groove c3. The size of the first gap h3 between the inset portion 1081 and the groove wall of the third groove c3 can be larger than the size of the second gap h4 between the protrusion 1082 and the edge of the opening of the third groove c3. For example, the size of the first gap h3 ranges from 0.05 mm to 0.1 mm, and the size of the second gap h4 ranges from 0.02 mm to 0.05 mm.

[0082] The fixed track 106, the movable track 107, and the slider 108 can form a three-section sliding track. The slider 203 can slide within the third groove c3 of the movable track 107, and the movable track 107 can slide within the second groove c2 of the fixed track 106. This allows control over the sliding trajectory of the sliding bracket 105, which is fixedly connected to the slider 108, causing the sliding bracket 105 to drive the second housing 102 to slide linearly along the second direction f2. As the second housing 102 slides away from the first housing 101, the second portion 1042 of the flexible display panel 104 wound around the scroll 103 gradually unfolds. As the second housing 102 slides closer to the first housing 101, the second portion 1042 of the flexible display panel 104 wound around the scroll 103 gradually contracts.

[0083] Optionally, such as Figure 7 As shown, the length of the moving track 107 is greater than the length of the fixed track 106. The three-section sliding track has a smaller size when stored, and after sliding open, the slider 108 can still be located in the moving track 107, and part of the moving track 107 can also be located in the fixed track 106, which can make the three-section sliding track more stable.

[0084] Optionally, such as Figure 7 As shown, the end of the moving track 107 away from the scroll 103 may have a baffle 1071, and the fixed track 106 is located on the side of the baffle 1071 closer to the scroll 103. The dimension of the baffle 1071 in the first direction f1 is larger than the dimension of the fixed track 106 in the first direction f1. The baffle 1071 can limit the moving track 107, preventing the moving track 107 from sliding off the fixed track 106, thereby improving the reliability of the connection between the moving track 107 and the fixed track 106.

[0085] Optionally, the sliding bracket 105 may have a strip-shaped second connector 1053. The second connector 1053 is located on the side of the first connector 1051 away from the scroll 103, and one end of the second connector 1053 is fixedly connected to the first connector 1051. The slider 108 has a first surface p7 facing away from the first housing 101, and the first surface p7 contacts the second connector 1053. The side of the second connector 1053 near the first surface p7 has multiple positioning grooves, and the side of the first surface p7 near the second connector 1053 has multiple positioning posts 1081. The positioning grooves and positioning posts 1081 can correspond one-to-one to limit the positioning of the second connector 1053 and the slider 108, thereby improving the connection reliability between the sliding bracket 105 and the slider 108. The number of fixed rails 106, moving rails 107, and sliders 108 can all be two or more.

[0086] The fixed track 106 may have an opening 1061 facing the second connector 1053, with the first surface p7 located within the opening 1061. That is, in the thickness direction f3 of the display device 10, the height of the first surface p7 is greater than the side of the moving track 107 near the second connector 1053, and the height of the first surface p7 is less than the side of the fixed track 106 near the second connector 1053. This reduces the overall thickness of the fixed track 106, the moving track 107, the slider 108, and the second connector 1053. The portion of the second connector 1053 that contacts the first surface p7 may be located within the opening 1061 of the fixed track 106, and the second connector 1053 may be further limited in the first direction f1 to improve its stability.

[0087] Optionally, such as Figure 10 As shown, Figure 10 This is a partial structural schematic diagram of a display device provided in an embodiment of this application. The sliding bracket 105 may further include a plurality of strip-shaped support members 1054 arranged parallel to each other along the first direction f1, one end of each support member 1054 being fixedly connected to the side of the first connecting member 1051 away from the scroll 103. Figure 2 As shown, the display device 10 may also include a plurality of strip-shaped support rails 109, which are located in the first housing 101 and fixedly connected to the first housing 101. The plurality of support rails 109 are slidably connected to the plurality of support members 1054 in a one-to-one correspondence.

[0088] Multiple support members 1054 can contact the second part 1042 of the flexible display panel 104 to support the second part 1042 of the flexible display panel 104, thereby preventing the second part 1042 of the flexible display panel 104 from collapsing after unfolding, and ensuring that the display surface of the second part 1042 of the display panel 104 has good flatness.

[0089] During the unfolding of the display device, the second housing 102 moves away from the first housing 101, causing a portion of the support member 1054 to be located outside the first housing 101, thus supporting the second portion 1042 of the flexible display panel 104. During the retraction of the display device, the second housing 102 moves towards the first housing 101, causing the support member 1054 to be located inside the first housing 101.

[0090] At least a portion of the support member 1054 may have a magnet on one side of the plane where the display surface of the first portion 1041 of the flexible display panel 104 is located, so that the portion of the support member 1054 can generate a magnetic attraction force with the display panel 104. In this way, the unfolded display panel 104 is relatively flat.

[0091] like Figure 11 and Figure 12 As shown, Figure 11 This is a schematic diagram of another display panel structure provided in an embodiment of this application. Figure 12 yes Figure 11 The diagram shows a cross-sectional structure of the support track along the C1-C2 position.

[0092] The cross-sectional shape of the support member 12 can be T-shaped, and the protruding edges on both sides can act as sliders, sliding along the C-shaped groove inside the support rail 109. The size of the gap h5 between the support member 1054 and the inner wall of the support rail 109 can be larger than the size of the gap h6 between the edge of the opening of the support member 1054 and the support rail 109. For example, the size of the gap h5 between the support member 1054 and the inner wall of the support rail 109 ranges from 0.2 mm to 0.3 mm, and the size of the gap h6 between the support member 1054 and the edge of the opening of the support rail 109 ranges from 0.1 mm to 0.2 mm. Furthermore, the support member 1054 protrudes from the support rail 109 in the thickness direction of the display device 10, so that the support member 1054 can contact the flexible display panel 104.

[0093] like Figure 11 As shown, the support member 1054 has a guide arc R at one end near the support track 109, which makes the sliding process of the support member 1054 in the support track 109 smoother. The radius of the guide arc R can be greater than or equal to 1 mm.

[0094] Optionally, such as Figure 13 As shown, Figure 13This is a schematic diagram of another display device provided in an embodiment of this application. The display device 10 may further include a sealing strip 110, which is fixedly connected to the first housing 101. The flexible display panel 104 may further include a binding portion 1043, which is encapsulated by the sealing strip 110. The sealing strip 110 has multiple columnar protrusions 1101 on the side near the first housing 101, and the first housing 101 has multiple fourth grooves. The multiple columnar protrusions 1101 are embedded in the multiple fourth grooves one by one. In this way, the sealing strip 110 and the first housing 101 can form a storage space for the binding portion 1043, which protects the binding portion 1043 and makes the connection between the sealing strip 110 and the first housing 101 more stable.

[0095] Optionally, such as Figure 14 and 15 As shown, Figure 14 This is a schematic diagram of another display device provided in an embodiment of this application. Figure 15 This is a schematic diagram of another display device provided in an embodiment of this application. The first housing 101 has a first base plate 1011 and a first side plate 1012 fixedly connected to the first base plate 1011. The second housing 102 has a second base plate 1021 and a second side plate 1022 fixedly connected to the second base plate 1021. The first side plate 1012 has an S-shaped first end face p5 near the second side plate 1022, and the second side plate 1022 has a second end face p6 matching the shape of the first end face near the first side plate 1012. When the display device 10 is in a retracted state, the first end face p5 and the second end face p6 are in contact. This allows for a larger contact area between the first end face p5 and the second end face p6, resulting in lower pressure per unit area after contact, thus protecting the user's hands. Furthermore, the contact area between the first side plate 1012 and the second side plate 1022 has a chamfer, for example, a C-angle. This prevents the contact surfaces of the first side plate 1012 and the second side plate 1022 from being flush, which could cause the user's fingers to be pinched when the plate is closed.

[0096] like Figure 16 As shown, Figure 16 yes Figure 15 The diagram shows a cross-sectional view of the display device along the D1-D2 position. The display device 10 may further include a fixed side plate 1013 located inside the first side plate 1012, which can be fixedly connected to the first base plate 1011. A second base plate 1021 is located on the side of the first base plate 1011 closest to the flexible display panel 104, and a second side plate 1022 is located on the side of the fixed side plate 1013 furthest from the flexible display panel 104.

[0097] The inner sidewall of the fixed side plate 1013 has a first groove c4 near the bottom of the first base plate 1011. The side of the second base plate 1021 is located in the groove c4 so that the second base plate 1021 is slidably connected to the fixed side plate 1013 and the second base plate 1021 and the first base plate 1011 can slide relatively parallel to each other.

[0098] The fixed side plate 1013 has a second groove c5 at one end away from the first floor 1011, and the second side plate 1022 has a strip protrusion c6, which can be located in the second groove c5 so that the second side plate 1022 is slidably connected to the fixed side plate 1013.

[0099] The height of the second side plate 1022 is slightly greater than the height of the fixed side plate 1013; the second side plate 1022 and the fixed side plate 1013 can be arranged in parallel to ensure that the first housing 101 and the second housing 102 can slide relatively parallel to each other.

[0100] The second side plate 1022 and the sliding bracket 105 can also be connected by bolts, so that the second side plate 1022 can be fixedly connected to the second base plate 1021. Figure 10 As shown, the side of the second side plate 1022 closest to the second bottom plate 1021 is not connected to the second bottom plate 1021, and there is a sliding clearance groove between the second side plate 1022 and the second bottom plate 1021. This sliding clearance groove allows the fixed side plate 1013 to be located between the second side plate 1022 and the second bottom plate 1021.

[0101] like Figure 17 As shown, Figure 17 This is a schematic diagram of another display panel structure provided in an embodiment of this application. Figure 17 This diagram shows a structural schematic of the display device 10 in its unfolded state from multiple perspectives. Specifically, Figure 17 The front K1, back K2, and four sides (top side K3, bottom side K4, left side K5, and right side K6) of the display device 10 are shown. When the display device 10 is in the unfolded state, the display surface of the display device 10 is large, which makes it easier for the user to operate on the display surface and provides the user with a better viewing experience.

[0102] In summary, this application provides a display panel comprising: a first housing, a second housing, a scroll, a flexible display panel, and a sliding bracket. The sliding bracket has adsorption portions arranged alternately with the scroll's roll in a first direction. The adsorption surfaces of these adsorption portions can adsorb onto a second portion of the flexible display panel. Thus, the adsorption force between the adsorption portions and the display panel reduces the impact of internal stress on the flexible display panel at the scroll, solving the problem of unevenness in certain areas of the display panel in related technologies, and improving the display effect of the display panel.
