Description

Technical Field

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

[0002] In recent years, organic light-emitting diodes (OLEDs) have attracted widespread attention for their flexibility and bendability. By folding or rolling up OLEDs, the space occupied by larger screens can be reduced, making them more portable. Therefore, foldable and rollable display devices are the main research directions for flexible OLEDs.

[0003] In existing technologies, when foldable and rollable display devices are folded or rolled up, the shape of the casing changes, and a portion of the flexible display panel cannot be supported by the casing. When the user clicks on this portion of the flexible display panel, there will be a pressing and sinking sensation.

[0004] Therefore, existing technologies have shortcomings and urgently need improvement. Summary of the Invention

[0005] This application provides a flexible display device and display equipment so that when the display equipment is folded or rolled up, no part of the flexible display panel is left unsupported by the housing, thereby avoiding the feeling of sinking when pressed.

[0006] This application provides a flexible display device, including:

[0007] The housing includes a first sub-housing and a second sub-housing disposed opposite to each other, the first sub-housing and the second sub-housing being relatively close to or far apart from each other, the first sub-housing and the second sub-housing being relatively far apart to adjust the housing to be in an open state, an opening being provided between the first sub-housing and the second sub-housing, and a gap being provided on at least one of the first sub-housing and the second sub-housing;

[0008] A flexible display panel is disposed on a first surface of the housing. When the first sub-housing and the second sub-housing are close to each other, at least one end of the flexible display panel extends into the gap and curls inside the housing. When the housing is in an open state, the flexible display panel is spread out on the surface of the housing.

[0009] A support structure is fixedly disposed inside the housing. The support structure has a support plate. When the first sub-housing and the second sub-housing are relatively close, the support plate is housed inside the housing. When the housing is in the open state, the support plate moves to the opening and abuts against the flexible display panel.

[0010] In the flexible display device described in this application, the side wall of the first sub-shell is provided with a first slide rail, the side wall of the second sub-shell is provided with a second slide rail, one end of the support plate is provided with a first slider, and the other end is provided with a second slider. The first slider slides along the first slide rail, and the second slider slides along the second slide rail to drive the support plate to move.

[0011] In the flexible display device described in this application, the first slide rail has a first end and a second end, the first end being away from the second sub-housing and the second end being close to the second sub-housing, and the distance between the first end and the first surface being greater than the distance between the second end and the first surface. The second slide rail has a third end and a fourth end, the third end being away from the first sub-housing and the fourth end being close to the first sub-housing, and the distance between the third end and the first surface being greater than the distance between the fourth end and the first surface.

[0012] In the flexible display device described in this application, the first sub-shell and the second sub-shell move closer together, causing the first slider to slide along a direction from the second end of the first slide rail toward the first end, and the second slider to slide along a direction from the fourth end of the second slide rail toward the third end. The support plate moves away from the first surface. The first sub-shell and the second sub-shell move away from each other, causing the first slider to slide along a direction from the first end of the first slide rail toward the second end, and the second slider to slide along a direction from the third end of the second slide rail toward the fourth end. The support plate moves closer to the first surface.

[0013] In the flexible display device described in this application, when the housing is in the open state, the first slider is located at the second end of the first slide rail, and the second slider is located at the fourth end of the second slide rail.

[0014] In the flexible display device described in this application, the first sub-shell has a first gap at the end away from the second sub-shell, and the second sub-shell has a second gap at the end away from the first sub-shell. When the first sub-shell and the second sub-shell are relatively close, the first end of the flexible display panel extends into the first gap and curls up inside the first sub-shell, and the second end of the flexible display panel extends into the second gap and curls up inside the second sub-shell.

[0015] In the flexible display device described in this application, the support structure further includes:

[0016] A base plate, which is fixed inside the housing;

[0017] The telescopic part is connected between the base plate and the support plate.

[0018] In the flexible display device described in this application, when the first sub-shell and the second sub-shell are close to each other, the telescopic part is in a retracted state to control the support plate to be housed inside the shell. When the shell is in an open state, the telescopic part is in an extended state to control the support plate to move to the opening and abut against the flexible display panel.

[0019] In the flexible display device described in this application, the telescopic part includes a first fixing part and a second fixing part. The first fixing part is fixedly connected to the side of the base plate facing the support plate and has a groove. The second fixing part is fixed to the side of the support plate facing the base plate and extends into the groove of the first fixing part and slides along the groove.

[0020] In the flexible display device described in this application, the support structure further includes:

[0021] A base plate is fixed inside the housing. Guide holes are provided on the base plate. A support plate is disposed on the base plate, and multiple guide posts are provided on the support plate opposite to the multiple guide holes so that the guide posts are embedded in the guide holes.

[0022] This application embodiment also provides a display device, the display device including a flexible display device, the flexible display device being the flexible display device described above.

[0023] The flexible display device provided in this application includes: a housing, the housing comprising a first sub-housing and a second sub-housing disposed opposite to each other, the first sub-housing and the second sub-housing being relatively close to or far apart from each other, the first sub-housing and the second sub-housing being relatively far apart to adjust the housing to be in an open state, an opening between the first sub-housing and the second sub-housing, and a gap provided on at least one of the first sub-housing and the second sub-housing; a flexible display panel disposed on a first surface of the housing, wherein when the first sub-housing and the second sub-housing are relatively close to each other, at least one end of the flexible display panel extends into the gap and is rolled up inside the housing, and when the housing is in an open state, the flexible display panel is spread out on the surface of the housing; and a support structure fixedly disposed inside the housing, the support structure having a support plate, wherein when the first sub-housing and the second sub-housing are relatively close to each other, the support plate is received inside the housing, and when the housing is in an open state, the support plate moves to the opening and abuts against the flexible display panel, so that when the display device is folded or rolled up, no part of the flexible display panel is not unsupported by the housing, thereby avoiding a feeling of sinking when pressed.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] In existing technologies, flexible screens have wide applications in future personal smart terminals due to their low power consumption and bendability. However, for existing devices with flexible screens, the size of the flexible screen is often too large to increase the operability and visual effect of the screen in the future. Furthermore, the flexible screen itself is bendable; when not in use, it is generally rolled into a housing. When operation is needed, the flexible screen is unfolded. However, because the flexible screen material is relatively soft and the bottom support is weak, the operating area is prone to denting when the user operates the flexible screen, resulting in a feeling of pressure and inconvenience.

[0033] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of a first structure of the flexible display device 100 provided in an embodiment of this application. Figure 2 This is a schematic diagram of a second structure of the flexible display device 100 provided in an embodiment of this application. Figure 3 This is a third structural schematic diagram of the flexible display device 100 provided in the embodiments of this application. The flexible display device 100 includes:

[0034] The housing 10 includes a first sub-housing 101 and a second sub-housing 102 disposed opposite to each other. The first sub-housing 101 and the second sub-housing 102 are relatively close to each other or relatively far apart. The first sub-housing 101 and the second sub-housing 102 are relatively far apart to adjust the housing 10 to be in an open state. An opening 103 is provided between the first sub-housing 101 and the second sub-housing 102. At least one of the first sub-housing 101 and the second sub-housing 102 is provided with a gap.

[0035] Flexible display panel 20 is disposed on the first surface 104 of housing 10. When the first sub-housing 101 and the second sub-housing 102 are close to each other, at least one end of the flexible display panel 20 extends into the gap and curls inside the housing 10. When the housing 10 is in the open state, the flexible display panel 20 is spread out on the surface of the housing 10.

[0036] The support structure 30 is fixedly disposed inside the housing 10. The support structure 30 has a support plate 301. When the first sub-housing 101 and the second sub-housing 102 are relatively close, the support plate 301 is housed inside the housing 10. When the housing 10 is in the open state, the support plate 301 moves to the opening 103 and abuts against the flexible display panel 20.

[0037] Specifically, Figure 1 This is a schematic diagram of the structure of the first sub-shell 101 and the second sub-shell 102 in the housing 10 of the flexible display device 100 in this application when they are relatively close. When the first sub-shell 101 and the second sub-shell 102 are relatively close, it can also be understood that the first sub-shell 101 moves in the X direction and the second sub-shell 102 moves in the negative X direction until the first sub-shell 101 and the second sub-shell 102 can no longer be relatively close.

[0038] At this point, it can be seen that the first end 201 of the flexible display panel 20 disposed on the first surface 104 of the housing 10 is curled up inside the first sub-housing 101, and the second end 202 of the flexible display panel 20 is curled up inside the second sub-housing 102. Here, in order to enable the first end 201 and the second end 202 of the flexible display panel 20 to be curled up, at least one end of the flexible display panel 20 can be connected to a coil spring, that is, the first end 201 and / or the second end 202 can be connected to a coil spring, thereby achieving the curled up setting. Furthermore, when the first sub-housing 101 and the second sub-housing 102 are relatively close, the flexible display panel 20 can also change from an unfolded state to a curled up state. A first gap 1011 is provided at the end of the first sub-shell 101 away from the second sub-shell 102, and a second gap 1021 is provided at the end of the second sub-shell 102 away from the first sub-shell 101. The first end 201 of the flexible display panel 20 passes through the first gap 1011 and enters the interior of the first sub-shell 101, and the second end 202 passes through the second gap 2021 and enters the interior of the second sub-shell 102.

[0039] Please see Figure 4 , Figure 4 This is a schematic diagram of the fourth structure of the flexible display device 100 in this application, that is, an intermediate schematic diagram of the process in which the first sub-shell 101 and the second sub-shell 102 move away from each other.

[0040] As can be seen, when the first sub-shell 101 and the second sub-shell 102 are relatively far apart, an opening 103 is formed between the first sub-shell 101 and the second sub-shell 102. At this time, due to the opening 103, the first end 201 of the flexible display panel 20 on the first surface 104, which is curled inside the first sub-shell 101, is pulled out from the first gap 1011; and the first end 202 of the flexible display panel 20, which is curled inside the second sub-shell 102, is pulled out from the second gap 1021. This solves the problem that the length of the flexible display panel 20 is insufficient due to the increase in the length of the flexible display device 100 in the X direction.

[0041] Furthermore, since a portion of the flexible display panel 20 in the open state is on the opening 103, a support structure 30 is also fixedly installed inside the housing 10. The support structure 30 has a support plate 301. When the first sub-housing 101 and the second sub-housing 102 are relatively close, the support plate 301 is housed inside the housing 10. When the housing 10 is in the open state, the support plate 301 moves to the opening 103 and abuts against the flexible display panel 20, thereby solving the problem that part of the flexible display panel 20 is not supported when the housing 10 is in the open state.

[0042] The flexible display device provided in this application embodiment includes a housing 10, which includes a first sub-housing 101 and a second sub-housing 102 disposed opposite to each other. The first sub-housing 101 and the second sub-housing 102 are either close to each other or far apart. The first sub-housing 101 and the second sub-housing 102 are relatively far apart to adjust the housing 10 to be in an open state. An opening 103 is provided between the first sub-housing 101 and the second sub-housing 102. At least one of the first sub-housing 101 and the second sub-housing 102 is provided with a gap. A flexible display panel 20 is disposed on a first surface 104 of the housing 10. When the first sub-housing 101 and the second sub-housing 102 are relatively close to each other, the flexible display panel 20 is disposed on the first surface 104 of the housing 10. The flexible display panel 20 has at least one end inserted into the housing 10. When the housing 10 is in the open state, the flexible display panel 20 is spread out on the surface of the housing 10. The support structure 30 is fixedly disposed inside the housing 10. The support structure 30 has a support plate 301. When the first sub-housing 101 and the second sub-housing 102 are relatively close, the support plate 301 is housed inside the housing 10. When the housing 10 is in the open state, the support plate 301 moves to the opening 103 and abuts against the flexible display panel 20. This is to avoid the technical problem that some flexible display panels 20 will not be supported by the housing 10 when the display device is folded or rolled up, thus avoiding the feeling of being pressed down.

[0043] Specifically, such as Figure 3 As shown, the first sub-shell 101 has a first gap 1011 at the end away from the second sub-shell 102, and the second sub-shell 102 has a second gap 1021 at the end away from the first sub-shell 101. When the first sub-shell 101 and the second sub-shell 102 are relatively close, the first end 201 of the flexible display panel 20 extends into the first gap 1011 and curls up inside the first sub-shell 101, and the second end 202 of the flexible display panel 20 extends into the second gap 1021 and curls up inside the second sub-shell 102.

[0044] Understandable, in comparison Figure 1 and Figure 2 , Figure 1 To allow the flexible display panel 20 to curl inside the second sub-housing 102 through the gap, a slit is provided only in the second sub-housing 102. Figure 2 A slit is provided only on the first sub-housing 101 so that the flexible display panel 20 can be rolled up inside the first sub-housing 101 through the slit. Figure 3 To provide gaps on both sides of the first sub-shell 101 and the second sub-shell 102, the first end 201 of the flexible display panel 20 is inserted into the first gap 1011 and rolled up inside the first sub-shell 101, and the second end 202 of the flexible display panel 20 is inserted into the second gap 1021 and rolled up inside the second sub-shell 102.

[0045] Specifically, the side wall of the first sub-shell 101 is provided with a first slide rail 1012, the side wall of the second sub-shell 102 is provided with a second slide rail 1022, one end of the support plate 301 is provided with a first slider 3011, and the other end is provided with a second slider 3012. The first slider 3011 slides along the first slide rail 1012, and the second slider 3012 slides along the second slide rail 1022 to drive the support plate 301 to move.

[0046] This is understandable; please refer to [link / reference]. Figure 5 , Figure 5 This is a fifth structural schematic diagram of the flexible display device 100 provided in this application embodiment. In this state, the housing 10 is in an open state. In order to drive the support plate 301 to move up and down in the Y direction when the first sub-housing 101 and the second sub-housing 102 are relatively close or relatively far apart in the X direction, a first slide rail 1012 is provided on the side wall of the first sub-housing 101, and a second slide rail 1022 is provided on the side wall of the second sub-housing 102. Correspondingly, a first slider 3011 and a second slider 3012 are provided opposite to each other on the side of the support plate 301. This allows the first slider 3011 to slide on the first slide rail 1012 and the second slider 3012 to slide on the second slide rail 1022, thereby driving the movement of the support plate 301.

[0047] Specifically, the first slide rail 1012 has a first end 10121 and a second end 10122. The first end 10121 is away from the second sub-housing 102, and the second end 10122 is close to the second sub-housing 102. The distance between the first end 10121 and the first surface 104 is greater than the distance between the second end 10122 and the first surface 104. The second slide rail 1022 has a third end 10221 and a fourth end 10222. The third end 10221 is away from the first sub-housing 101, and the fourth end 10222 is close to the first sub-housing 101. The distance between the third end 10221 and the first surface 104 is greater than the distance between the fourth end 10222 and the first surface 104.

[0048] It is understandable that in order to enable the support plate 301 to move in the Y direction, it is necessary to limit the distance between the end of the slide rail and the first surface 104. Taking the first slide rail 1012 as an example, since the distance from the first end 10121 of the first slide rail 1012 to the first surface 104 is greater than the distance from the second end 10122 to the first surface 104, when the housing 10 moves from the closed to the open state or from the open to the closed state, the first slider 3011 slides in the first slide rail 1012, thereby driving the support plate 301 to move in the Y direction.

[0049] Specifically, the first sub-shell 101 and the second sub-shell 102 move closer to each other, causing the first slider 3011 to slide along the direction from the second end 10122 of the first slide rail 1012 toward the first end 10121, and the second slider 3012 to slide along the direction from the fourth end 10222 of the second slide rail 1022 toward the third end 10221. The support plate 301 moves away from the first surface 104. The first sub-shell 101 and the second sub-shell 102 move away from each other, causing the first slider 3011 to slide along the direction from the first end 10121 of the first slide rail 1012 toward the second end 10122, and the second slider 3012 to slide along the direction from the third end 10221 of the second slide rail 1022 toward the fourth end 10222. The support plate 301 moves closer to the first surface 104.

[0050] It is understood that this section specifically describes the movement of the first slider 3011 and the second slider 3012 in the first slide rail 1012 and the second slide rail 1022 respectively when the first sub-shell 101 and the second sub-shell 102 are relatively close or relatively far apart, and the way in which the first slider 3011 and the second slider 3012 drive the support plate 301 to move closer to or away from the first surface 104 when they move.

[0051] Specifically, when the housing 10 is in the open state, the first slider 3011 is located at the second end 10122 of the first slide rail 1012, and the second slider 3012 is located at the fourth end 10222 of the second slide rail 1022.

[0052] It is understood that this is to define the initial positions of the first slider 3011 and the second slider 3012 so that when the housing 10 changes from the closed state to the open state or from the open state to the closed state, the first slider 3011 and the second slider 3012 can slide in the first slide rail 1012 and the second slide rail 1022 respectively, thereby defining that when the support plate 301 changes from the closed state to the open state, it moves closer to the first surface 104 along the Y direction, and when it changes from the open state to the closed state, it moves away from the first surface 104 along the negative Y direction.

[0053] Specifically, the support structure 30 also includes:

[0054] Base plate 302, which is fixed inside housing 10;

[0055] Telescopic part 303 is connected between base plate 302 and support plate 301.

[0056] It is understandable that, in order to avoid the support plate 301 being too high at one end and too low at the other end due to the movement of one end too fast during the movement of the first sub-shell 101 and the second sub-shell 102 in the X direction, a telescopic part 303 can be provided below the support plate 301, so that the support plate 301 can only move in the Y direction. The other end of the telescopic part 303 is connected and fixed to the bottom plate inside the shell 10 to ensure the overall stability.

[0057] Specifically, when the first sub-shell 101 and the second sub-shell 102 are relatively close, the telescopic part 303 is in a retracted state to control the support plate 301 to be housed inside the shell. When the shell 10 is in an open state, the telescopic part 303 is in an extended state to control the support plate 301 to move to the opening 103 and abut against the flexible display panel 20.

[0058] The telescopic part 303 here has the functions of retracting and extending. It can extend the housing 10 from the closed state to the open state to abut against the support plate 301 and move it toward the first surface 104; and retract the housing 10 from the open state to the closed state to abut against the support plate 301 and move it toward the first surface 104.

[0059] Specifically, the telescopic part 303 includes a first fixing part 3031 and a second fixing part 3032. The first fixing part 3031 is fixedly connected to the side of the base plate 302 facing the support plate 301 and has a groove. The second fixing part 3032 is fixed to the side of the support plate 301 facing the base plate 302 and extends into the groove of the first fixing part and slides along the groove. It can be understood that the working principle of the telescopic part 303 is specifically described here.

[0060] In another embodiment, such as Figure 6 As shown, Figure 6 This is a sixth structural schematic diagram of the flexible display device 100 provided in the embodiments of this application. The support structure 30 further includes:

[0061] The base plate 302 is fixed inside the housing 10. A guide hole 3021 is provided on the base plate 302. A support plate 301 is provided on the base plate 302. A plurality of guide posts 3013 are provided in the multiple guide holes 3021 on the support plate 301 so that the guide posts 3013 are embedded in the guide holes 3021.

[0062] Specifically, guide holes 3021 can be directly made on the base plate 302. These guide holes 3021 can be through holes or via holes; no limitation is made here. A guide post 3013 can be provided on the side of the support plate 301 facing the base plate 302, and positioned relative to the guide hole 3021, which can also achieve movement of the support plate 301 in the Y direction. The cross-sectional shape of the guide post 3013 can be the same as the cross-sectional shape of the guide hole 3021, such as circular, square, or rhomboid; details are omitted here.

[0063] The flexible display device provided in this application embodiment includes: a housing 10, the housing 10 including a first sub-housing 101 and a second sub-housing 102 disposed opposite to each other, the first sub-housing 101 and the second sub-housing 102 being relatively close to each other or relatively far apart, the first sub-housing 101 and the second sub-housing 102 being relatively far apart to adjust the housing 10 to be in an open state, an opening 103 being provided between the first sub-housing 101 and the second sub-housing 102, and a gap being provided on at least one of the first sub-housing 101 and the second sub-housing 102; and a flexible display panel 20, the flexible display panel 20 being disposed on a first surface 104 of the housing 10, opposite to the first sub-housing 101 and the second sub-housing 102. When brought close together, at least one end of the flexible display panel 20 extends into the housing 10. When the housing 10 is in the open state, the flexible display panel 20 is spread out on the surface of the housing 10. The support structure 30 is fixedly disposed inside the housing 10. The support structure 30 has a support plate 301. When the first sub-housing 101 and the second sub-housing 102 are close to each other, the support plate 301 is housed inside the housing 10. When the housing 10 is in the open state, the support plate 301 moves to the opening 103 and abuts against the flexible display panel 20, so that when the display device is folded or rolled up, no part of the flexible display panel 20 will be left unsupported by the housing 10, thereby avoiding the feeling of being pressed down. Furthermore, the support structure 30 of this application connects the first slide rail 1012 and the second slide rail 1022 on the housing 10 via the first slider 3011 and the second slider 3012 on the side of the support plate 301, thereby enabling the support plate 301 to move in the Y direction when the first housing 301 and the second housing 302 move in the X direction; secondly, the extension 303 or the cooperation between the guide hole 3021 and 3013 prevents the support plate 301 from tilting during the movement.

[0064] Accordingly, this application also provides a display device, including a flexible display device 100 according to any embodiment of this application. For the specific structure of the flexible display device 100, please refer to the previous embodiments, which will not be repeated here.
