Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a flexible display device. Background Art

[0002] With the development of display technology, flexible display technology is becoming increasingly mature. Among these, rollable and retractable screens are gaining increasing attention in the industry for foldable electronic terminal displays. The flexible display panel of a rollable and retractable screen can switch between a display area and a storage area.

[0003] However, when the existing sliding and retractable screen is sliding and switching, the film layer at its end is easily separated. Summary of the Invention

[0004] The main technical problem solved by the present invention is to provide a flexible display device to reduce the probability of film separation when the flexible display panel slides.

[0005] To solve the above technical problems, the present invention adopts a technical solution: providing a flexible display device, comprising a flexible display panel and a sliding mechanism, wherein in the length direction of the flexible display panel, the flexible display panel comprises a display area and a non-display area connected to each other; and in the thickness direction of the flexible display panel, the flexible display panel comprises a first surface and a second surface disposed opposite to each other;

[0006] The sliding mechanism includes a first fixing member and a second fixing member arranged opposite to each other, and a load applying mechanism, wherein the first fixing member is used to be fixedly connected to the first surface of the non-display area of ​​the flexible display panel, and the second fixing member is used to be fixedly connected to the second surface of the non-display area of ​​the flexible display panel;

[0007] The sliding mechanism further includes the load applying mechanism for applying a first force to the flexible display panel in the non-display area away from the display area through the first fixing member and the second fixing member.

[0008] Preferably, the load applying mechanism is connected to the first fixing member and the second fixing member; wherein the load applying mechanism includes a first sub-load applying mechanism and a second sub-load applying mechanism, the first sub-load applying mechanism being connected to the first fixing member, and the second sub-load applying mechanism being connected to the second fixing member, the first sub-load applying mechanism being used to apply a first sub-force away from the display area to the first fixing member, and the second sub-load applying mechanism being used to apply a second sub-force away from the display area to the second fixing member, the combined force of the first sub-force and the second sub-force being the first force. The two sub-load applying mechanisms are used to apply forces to the two surfaces of the non-display area, respectively, to reduce the probability of display panel peeling while ensuring the support strength of the display panel.

[0009] Preferably, the second surface is close to the side of the flexible display panel where the cover plate is provided; the second sub-force is greater than or equal to the first sub-force. By increasing the second sub-force close to the second surface, the misalignment of the film layer is further reduced, thereby reducing the probability of film separation in the non-display area.

[0010] Preferably, the sliding mechanism further comprises a connecting member disposed on one side of the first fixing member and the second fixing member and connected thereto; wherein the load applying mechanism is connected to the connecting member and is configured to apply the first force to the connecting member away from the display area. By acting on the connecting member, the load applying mechanism simultaneously acts on the first and second fixing members. Only a single drive mechanism is required to apply force to both fixing members, thereby simplifying the structure and reducing costs.

[0011] Preferably, the second surface is close to the side of the flexible display panel on which the cover plate is provided; the load-applying mechanism applies multiple loads to the connector away from the display area, the multiple loads being distributed on the side of the connector away from the first and second fixing members, the multiple loads gradually increasing in a direction from the first surface toward the second surface, and the resultant force of the multiple loads being the first applied force. The load-applying mechanism applies a linear load to the connector. Because each film layer shares the load of the first applied force, the misalignment between the film layers is reduced, and the gradually increasing load adapts to the increasing misalignment of the film layers along that direction.

[0012] Preferably, the second surface is close to a side of the flexible display panel on which a cover plate is provided; and in the thickness direction of the flexible display panel, the distance between the first force and the first surface is greater than or equal to the distance between the first force and the second surface. The force arm of the second sub-force is less than or equal to the force arm of the first sub-force, such that the second sub-force is greater than or equal to the first sub-force, further reducing the probability of delamination of the film layers while simplifying the structure and reducing costs.

[0013] Preferably, the load applying mechanism includes a first sub-load applying mechanism and a second sub-load applying mechanism, wherein the first sub-load applying mechanism is connected to the first fixing member and is configured to apply a first sub-force to the first fixing member; the second sub-load applying mechanism is configured to apply a second sub-force toward the first fixing member to the second fixing member, so that when the flexible display panel slides, the second fixing member applies a third sub-force to the flexible display panel away from the display area; wherein the combined force of the first sub-force and the third sub-force is the first force. When the second sub-load applying mechanism applies pressure to the second fixing member, it increases the pressure between the film layers in the non-display area of ​​the flexible display panel, thereby increasing the static friction between the second fixing member and the flexible display panel and the static friction between the film layers, thereby reducing the probability of peeling between the film layers.

[0014] Preferably, the second fixing member is disposed on a side of the flexible display panel adjacent to the cover plate, and the third sub-force is greater than or equal to the first sub-force. By increasing the third sub-force on the side adjacent to the second surface, the extent of film misalignment is further reduced, thereby reducing the probability of film separation in the non-display area.

[0015] Preferably, the first fixing member is a rigid member, and the second fixing member is an elastic member, which is compressed and disposed between the second sub-load applying mechanism and the flexible display panel. The elastic member can always provide a stable and continuous pressure to the flexible display panel, without the need for additional drive mechanisms such as motors and cylinders.

[0016] Preferably, the second sub-load applying mechanism includes a slide rail extending along the sliding direction of the flexible display panel; wherein the elastic member is compressed and disposed between the flexible display panel and the slide rail, and the elastic member is slidably connected to the slide rail. The slide rail reduces frictional forces on the elastic member during sliding and guides the flexible display panel to slide along a predetermined trajectory.

[0017] Preferably, the length of the non-display area is 10-50 mm.

[0018] The beneficial effects of the present invention are as follows: Different from the prior art, the sliding mechanism of the present invention is provided with fixing parts on both surfaces of the non-display area of ​​the flexible display panel, and a first force away from the display area is applied to the two fixing parts through a load application mechanism, that is, a tensile force is applied to both surfaces of the flexible display panel to stretch the display panel, so that each film layer of the flexible display panel shares the tensile force that originally only acts on one side of the flexible display panel. The direction of the tensile force applied by the present invention is opposite to the direction of the book page-like misalignment of each film layer in the non-display area, thereby slowing down the relative displacement between the film layers in the non-display area of ​​the flexible display panel; and because at least part of the first force applies a tensile force to the second surface of the non-display area through the second fixing part, the maximum misalignment amplitude of the film layer on the side of the flexible display panel close to the second surface is reduced. The sliding mechanism in the flexible display device of the present invention reduces the deformation amplitude and force of the adhesive between the film layers, thereby reducing the probability of separation of the film layers in the non-display area. Different from the prior art, the flexible display device of the present invention increases the length of the non-display area, so that when the effective display area of ​​the flexible display panel reaches its maximum value, the end of the non-display area is at a certain distance from the bending axis, thereby reducing the rebound force on the end of the non-display area and reducing the probability of peeling between the film layers in the non-display area.

[0027] To make the objectives, technical solutions, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It is apparent that the described examples are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0028] See Figure 1 , Figure 1 : This is a structural diagram of a first embodiment of a flexible display device. The flexible display device of the present invention includes a flexible display panel 4 and a sliding mechanism. The flexible display panel 4 that can slide and retract is bent along the bending axis 7. The flexible display panels 4 located on both sides of the bending axis 7 are respectively an effective display area A and a storage area B. The flexible display panel 4 located in the effective display area A is visible to the user, and the flexible display panel 4 located in the storage area B is invisible to the user. The sliding mechanism is used to retract and slide the flexible display panel 4, by driving the bending axis 7 along the vertical direction ( Figure 1 The flexible display panel 4 moves (in the direction of the dashed arrow), thereby causing the flexible display panel 4 to expand and contract and slide along its length, changing the length of the effective display area A, thereby changing the effective display area of ​​the flexible display panel 4. Along the length of the flexible display panel 4, the flexible display panel 4 includes a connected display area 401 and a non-display area 402, wherein the non-display area 402 is always located in the storage area B. At least a portion of the display area 401 adjacent to the non-display area 402 can bend and slide along the bending axis 7, switching between the effective display area A and the storage area B, thereby changing the effective display area of ​​the flexible display panel 4. In addition, the sliding mechanism also includes a load application mechanism for applying a force away from the flexible display panel 4 to each end of the flexible display panel 4, so that the flexible display panel 4 always maintains a tensioned state, thereby keeping the panel flat. The load application mechanism includes a second force F0 acting on one end of the effective display area A and a first force F acting on one end of the storage area B.

[0029] Continue reading Figure 1, in the thickness direction of the flexible display panel 4, the flexible display panel 4 includes a first surface 4a and a second surface 4b arranged opposite to each other. The sliding mechanism of the present invention includes a first fixing member 1 and a second fixing member 2 arranged opposite to each other, the first fixing member 1 is used to be fixedly connected to the first surface 4a of the non-display area 402 of the flexible display panel 4, and the second fixing member 2 is used to be fixedly connected to the second surface 4b of the non-display area 402 of the flexible display panel 4. Specifically, the first fixing member 1 and the second fixing member 2 can be adhered to the first surface 4a and the second surface 4b respectively. The sliding mechanism may further include a third fixing member 5, and the third fixing member 5 is used to be fixedly connected to the first surface 4a of the display area 401 of the flexible display panel 4. The sliding mechanism also includes a load applying mechanism (not shown in the figure) for applying a load away from the display area 401 (along the non-display area 402) to the non-display area 402 through the first fixing member 1 and the second fixing member 2. Figure 1 The load applying mechanism can also be used to apply a first force F away from the display area 401 (along the X direction) to the display area 401 through the third fixing member 5. Figure 1 Specifically, the load applying mechanism may include a driving mechanism such as a motor and a cylinder.

[0030] The sliding mechanism of the present invention is provided with a first fixing member 1 and a second fixing member 2 on the first surface 4a and the second surface 4b of the non-display area 402 of the flexible display panel 4, respectively, and a first force F away from the display area 401 is applied to the first fixing member 1 and the second fixing member 2 through a load applying mechanism, that is, a tensile force is applied to the first surface 4a and the second surface 4b of the flexible display panel 4 to stretch the flexible display panel 4, thereby ensuring that the flexible display panel 4 always remains flat during the sliding process, and at the same time, each film layer of the flexible display panel 4 along the thickness direction is subjected to a tensile force away from the display area 401. According to the inventor's observation, after the flexible display panel 4 is bent, due to the inconsistent bending radius of each film layer, each film layer is prone to book page dislocation, thereby causing the film layer separation phenomenon at the end of the flexible display panel 4 when sliding. The direction of the tensile force applied by the present invention ( Figure 1 The first force F (in the X-direction) is in the opposite direction of the book-page misalignment of the film layers in the non-display area 402, thereby reducing the relative displacement between the film layers in the non-display area 402 of the flexible display panel 4. The inventors also discovered that the film layers on the side of the flexible display panel 4 closest to the outer surface (in this embodiment, the second surface 4b) have the greatest misalignment. Because at least part of the first force F applies a tensile force to the second surface 4b of the non-display area 402 via the second fixing member 2, the misalignment of the film layers on the side of the flexible display panel 4 closest to the second surface 4b is reduced. The sliding mechanism of the flexible display device of the present invention reduces the deformation and force of the adhesive between the film layers in the non-display area 402, thereby reducing the probability of separation of the film layers in the non-display area 402.

[0031] Optionally, the first fixing member 1 and the second fixing member 2 can be fixed to the end of the non-display area 402 away from the display area 401. Since the end has the largest misalignment amplitude and the highest peeling probability, the above technical means can be used to reduce the peeling probability at the end.

[0032] Optionally, the load applying mechanism may act on the first fixing member 1 and the second fixing member 2 separately, or may act on the first fixing member 1 and the second fixing member 2 simultaneously.

[0033] exist Figure 1 In the illustrated embodiment 1, the load applying mechanism is connected to the first fixing member 1 and the second fixing member 2; wherein the load applying mechanism includes a first sub-load applying mechanism (not shown) and a second sub-load applying mechanism (not shown), the first sub-load applying mechanism being connected to the first fixing member 1, and the second sub-load applying mechanism being connected to the second fixing member 2. The first sub-load applying mechanism is used to apply a first sub-force F1 to the first fixing member 1 away from the display area 401, and the second sub-load applying mechanism is used to apply a second sub-force F2 to the second fixing member 2 away from the display area 401. The resultant force of the first sub-force F1 and the second sub-force F2 is the first force F. Specifically, the first sub-load applying mechanism and the second sub-load applying mechanism can be one or more drive mechanisms such as a motor, a cylinder, etc., and are fixedly connected to the first fixing member 1 and the second fixing member 2, respectively, to apply forces to the first fixing member 1 and the second fixing member 2.

[0034] Further, see Figure 1 , the second sub-force F2 is greater than or equal to the first sub-force F1. Since the film layer misalignment amplitude increases closer to the second surface 4b in the thickness direction of the flexible display panel 4, increasing the second sub-force F2 closer to the second surface 4b further reduces the film layer misalignment amplitude, thereby reducing the probability of film layer separation in the non-display area 402.

[0035] See Figure 2 , Figure 2 Figure 2 is a schematic diagram of the structure of a second embodiment of a flexible display device. In this embodiment, the sliding mechanism further includes a connecting member 3, disposed on one side of the first fixing member 1 and the second fixing member 2, and connected to the first fixing member 1 and the second fixing member 2. Specifically, the connecting member 3 can be connected across the side of the first fixing member 1 and the second fixing member 2 facing away from the display area 401. A load-applying mechanism (not shown) is connected to the connecting member 3 and is used to apply a first force F to the connecting member 3 away from the display area 401. In this embodiment, the load-applying mechanism acts on the connecting member 3 to simultaneously apply force to the first fixing member 1 and the second fixing member 2. Only a single drive mechanism, such as a motor or cylinder, is required to apply force to both fixing members, thereby simplifying the structure and reducing costs.

[0036] Further, if Figure 3 As shown, Figure 3 Schematic diagram of the partial structure of the flexible display device of the present invention. In the thickness direction of the flexible display panel 4, along the direction from the first surface 4a to the second surface 4b ( Figure 3 The flexible display panel 4 includes a metal support layer 41, a first adhesive layer 42, a support film layer 43, a screen body 44, a polarizing layer 45 and a cover plate 46 stacked in sequence. The connecting member 3 is arranged across one side of the first fixing member 1 and the second fixing member 2, and is connected to the first fixing member 1 and the second fixing member 2. A force-applying member 31 is fixedly connected to the connecting member 3. In the thickness direction of the flexible display panel 4, the distance d1 between the force-applying member 31 and the first surface 4a is greater than or equal to the distance d2 between the force-applying member 31 and the second surface 4b; a load applying mechanism (not shown) is connected to the force-applying member 31, and is used to apply a first force F away from the display area 401 to the connecting member 3, so that the distance between the first force F and the first surface 4a is greater than or equal to the distance between the first force F and the second surface 4b. The first force F includes two components, a first sub-force F1 and a second sub-force F2, acting on the first fixing member 1 and the second fixing member 2 respectively. Since the force arm of the second sub-force F2 relative to the force-applying member 31 is less than or equal to the force arm of the first sub-force F1, the second sub-force F2 is greater than or equal to the first sub-force F1. By changing the position of the force-applying member 31 in the thickness direction, the relative sizes of the two components can be changed, thereby achieving the goal of applying forces of different sizes to the first fixing member 1 and the second fixing member 2 with only one load applying mechanism, further reducing the probability of peeling of each film layer (especially the cover plate 46 close to the second surface 4b), simplifying the structure and reducing costs.

[0037] Optionally, see Figure 4 , Figure 4 The load applying mechanism (not shown) applies a load to the connecting member 3 away from the display area 401 ( Figure 4 The multiple loads p are distributed on the side of the connecting member 3 away from the first fixing member 1 and the second fixing member 2, and the multiple loads p are directed along the first surface 4a to the second surface 4b ( Figure 4 The load gradually increases in the Z direction, and the resultant force of the multiple loads is the first force F. Specifically, in this embodiment, the load application mechanism applies a linear load to the connector 3. Because each film layer equally shares the load p of the first force F, the misalignment between the film layers is reduced. The gradually increasing load in the Z direction adapts to the increasing misalignment of the film layers along this direction. In other embodiments, the load can be nonlinear.

[0038] Alternatively, see Figure 5 , Figure 52 is a schematic structural diagram of a fifth embodiment of the flexible display device of the present invention.

[0039] The load applying mechanism (not shown) includes a first sub-load applying mechanism and a second sub-load applying mechanism. The first sub-load applying mechanism is connected to the first fixing member 1 and is used to apply a first sub-force F1 to the first fixing member 1; the second sub-load applying mechanism is used to apply a second sub-force F2 toward the first fixing member 1 to the second fixing member 2, so that when the flexible display panel 4 slides, the second fixing member 2 applies a third sub-force F3 away from the display area to the flexible display panel 4; wherein, the resultant force of the first sub-force F1 and the third sub-force F3 is the first force F.

[0040] The second sub-force F2 is the pressure applied by the second sub-load applying mechanism to the second fixing member 2, that is, the pressure applied by the second fixing member 2 to the flexible display panel 4. Since the second fixing member 2 and the flexible display panel 4 are relatively stationary, the third sub-force F3 is the static friction force applied by the second fixing member 2 in the opposite direction of the sliding direction to the flexible display panel 4 when the flexible display panel 4 slides. The first sub-force F1 and the third sub-force F3 are in the same direction, forming a resultant first force F acting on the flexible display panel 4. The application of the second sub-force F2 increases the pressure between the various film layers in the non-display area 402 of the flexible display panel 4, thereby increasing the static friction between the second fixing member 2 and the flexible display panel 4 and the static friction between the various film layers, thereby reducing the probability of delamination between the film layers. Optionally, the second sub-force F2 can be a uniformly distributed load, and the second sub-force F2 can be applied by a drive mechanism such as a motor or cylinder.

[0041] See Figure 6 , Figure 6 This is a comparison diagram of the stresses on the various film layers before and after implementation of Example 5 of the flexible display device of the present invention. Line way1 depicts the stress between the various film layers in the direction from the metal support layer 41 toward the cover plate 46 along the thickness of the flexible display panel 4 before the improvement, while line way3 depicts the stress between the various film layers in the direction from the metal support layer 41 toward the cover plate 46 along the thickness of the flexible display panel 4 after the improvement. As can be seen from the figure, with the exception of the increased stress between the cover plate 46 and the polarizing layer 45, the stresses between the remaining film layers have all been reduced by at least 25%. It should be noted that although the stress between the cover plate 46 and the polarizing layer 45 has increased, the stress value remains at a low level and is unlikely to cause delamination of the film layers.

[0042] Furthermore, the second fixing member 2 is disposed on the side of the flexible display panel 4 where the cover plate 46 (i.e., the second surface 4b) is provided, and the third sub-force F3 is greater than or equal to the first sub-force F1. Because the film layer misalignment increases toward the second surface 4b in the thickness direction of the flexible display panel 4, increasing the third sub-force F3 toward the second surface 4b further reduces the misalignment, thereby reducing the probability of separation of the film layers.

[0043] Optionally, the first fixing member 1 is a rigid member, and the second fixing member 2 is an elastic member, which is compressed and arranged between the second sub-load applying mechanism and the flexible display panel 4. Since the elastic member is compressed to store energy and is always fixed to the flexible display panel 4, the elastic member can move synchronously with the flexible display panel 4, thereby always providing a stable pressure to the flexible display panel 4. Moreover, since the elastic member can be compressed between the housing of the display device and the flexible display panel 4 to provide continuous pressure, there is no need to set up additional drive mechanisms such as motors and cylinders.

[0044] Optionally, see Figure 7 , Figure 7 Schematic diagram of the structure of the flexible display device of the present invention. The second sub-load applying mechanism includes a slide rail 61, which is arranged along the sliding direction of the flexible display panel 4 ( Figure 6 The elastic member is compressed and disposed between the flexible display panel 4 and the slide rail 61, and is slidably connected to the slide rail 61. This reduces friction on the elastic member during sliding and guides the flexible display panel 4 along a predetermined trajectory. Furthermore, a slider can be slidably disposed on the slide rail 61, with the elastic member fixedly connected to the slider to further reduce friction. Optionally, the slide rail 61 can be fixed to the display device housing 6.

[0045] Optionally, see Figure 8 , Figure 8 This is a schematic diagram of the structure of an embodiment of the flexible display device of the present invention when the sliding distance is maximum. The length of the non-display area 402 of the flexible display panel 4 is 10-50 mm. The inventors have discovered that the closer the non-display area 402 is to the bending axis 7, the greater the probability of delamination of the film layer at its end. By lengthening the non-display area 402, when the sliding distance of the flexible display panel 4 is maximum, that is, when the effective display area A reaches its maximum value, the distance between the end of the non-display area 402 and the bending axis 7 is lengthened, reducing the rebound force on the end of the non-display area 402 and the probability of delamination between the film layers in the non-display area.

[0046] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
