Detailed Description

Features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The embodiments will be described in detail below with reference to the accompanying drawings.

In one aspect, the embodiment of the present application provides a flexible display module 100, including a support assembly 3 and a flexible display panel 1, where the support assembly 3 includes a flexible support substrate 31 and an adjusting member 33, and the adjusting member 33 is movably connected to a side surface of the flexible support substrate 31 in a thickness direction; the flexible display panel 1 is fixedly connected to the adjusting member 33; the flexible display module 100 has a flat state in which the adjusting member 33 is located at the first position and a curved state in which the adjusting member 33 moves to the second position along the plane where the flexible support substrate 31 is located, and the flexible support substrate 31 and the flexible display panel 1 are curved to compensate for a deviation between the first position and the second position.

In the flexible display module assembly and the flexible display device that this application embodiment provided, but through regulating part and flexible supporting substrate swing joint setting, regulating part and flexible display panel fixed connection set up simultaneously, thereby can be through the position relation who changes regulating part and flexible supporting substrate, adjust flexible display panel and flexible supporting substrate relative position relation, make flexible display module assembly can be through the size of control regulating part moving direction and migration distance when switching under flat state and the crooked state, can control flexible display module assembly to crooked with different curvatures to different directions, satisfy user's different demands.

Optionally, the flexible display panel 1 may be an Organic Light-Emitting Diode (OLED) panel, and in other embodiments, may also be a flexible display panel 1 such as a flexible quantum dot, electronic paper, and the like, in this embodiment, the type of the flexible display panel 1 is not specifically limited, and any flexible and bendable display panel falls within the protection scope of this embodiment. The flexible supporting substrate 31 may be made of a material having a certain deformation capability, so that the flexible supporting substrate 31 can support and protect the flexible display panel 1 on one hand, and can bend together with the flexible display panel 1 on the other hand. The flexible supporting substrate 31 may also be made of various materials, for example, in the flexible supporting substrate 31, the region connected to the adjusting member 33 is made of a hard material to support and protect the flexible display panel 1, and the region not connected to the adjusting member 33 is made of a flexible deformable material and can be bent to a desired angle under the action of an external force.

The flexible display module 100 in the embodiment of the present application can be switched between the flat state and the curved state. When the flexible display module 100 is in a flat state, the display surface of the flexible display module 100 is planar, and a user can see a planar image through the planar flexible display module 100; when flexible display module assembly 100 is in the curved state, the display surface of flexible display module assembly 100 is the curved surface form, and the user sees the curved surface image through flexible display module assembly 100, richens the visual angle that the user watched. The embodiment of the present application controls the flexible display module 100 to switch between the flat state and the curved state by moving the adjusting member 33. One side of the adjusting member 33 is fixedly connected with the flexible display panel 1, so that the positions of the adjusting member 33 and the flexible display panel 1 are relatively fixed, and the other side of the adjusting member 33 is movably connected with the flexible support substrate 31, so that the relative positions of the adjusting member 33 and the flexible support substrate 31 can be adjusted, and thus the relative positions of the flexible display panel 1 and the flexible support substrate 31 can be adjusted through the adjusting member 33. In the case where the adjuster 33 is moved from the first position to the second position so that the relative positions of the flexible display panel 1 and the flexible support substrate 31 are changed, the adjuster 33 applies pressure to the flexible display panel 1 or the flexible support substrate 31 so that the flexible display panel 1 and the flexible support substrate 31 are bent together to compensate for a deviation in movement of the adjuster 33 between the first position and the second position.

The principle of the adjuster 33 bending the flexible display panel 1 will be described with reference to fig. 1 and 2. In the example shown in fig. 1 and 2, the flexible display panel 1 is a rectangular panel, the adjusting member 33 is disposed at the left end of the flexible display panel 1, the flexible display panel 1 and the flexible support substrate 31 are respectively connected to two sides of the adjusting member 33, the connecting member 8 is disposed at the right end of the flexible display panel 1, and the flexible display panel 1 and the flexible support substrate 31 are fixedly connected by the connecting member 8. In fig. 1, the adjusting member 33 is in the first position, the edge of the flexible display panel 1 coincides with the edge of the flexible support substrate 31, the distance from the connection point a of the flexible display panel 1 and the adjusting member 33 to the connection point B of the flexible display panel 1 and the connection member 8 is D1, the distance from the connection point C of the flexible support substrate 31 and the adjusting member 33 to the connection point D of the flexible support substrate 31 and the connection member 8 is D2, and at this time, the flexible display module 100 is in a flat state, and D1 and D2 are equal. In fig. 2, the adjusting member 33 moves to the second position in the direction approaching the connecting member 8, the edge of the flexible display panel 1 and the edge of the flexible support substrate 31 are no longer overlapped, because the flexible display panel 1 is fixedly connected with the adjusting member 33, the flexible display panel 1 and the adjusting member are still in the connection state at point a, the distance from the connection point a of the flexible display panel 1 and the adjusting member 33 to the connection point B of the flexible display panel 1 and the connecting member 8 is still D1, the adjusting member 33 and the flexible support substrate 31 are relatively displaced, so that the connection point of the flexible display panel 1 and the adjusting member 33 is at point C ', at this time, the edge of the flexible support substrate 31 and the adjusting member 33 is connected at point C ', and the distance from the connection point C ' to the connection point D3 of the flexible support substrate 31, the adjusting member 33 applies pressure to the flexible support substrate 31, so that the flexible support substrate 31 is under the action of pressure, a certain degree of bending occurs to compensate for the deviation between d2 and d3, i.e. the distance the adjustment member 33 moves. Since d1 is larger than d3, the curvature radius corresponding to the flexible display panel 1 in the curved flexible display module 100 is larger than the curvature radius corresponding to the flexible support substrate 31, so that the display surface of the flexible display panel 1 is convexly curved.

It can be understood that the flexible display module 100 in the embodiment of the present application is not limited to a rectangle, and may also be a structure with any shape; the adjusting member 33, the flexible supporting substrate 31 and the flexible display panel 1 are not limited to the connection manner of overlapping edges, and a person skilled in the art can set the adjusting member 33 to be connected to any position of the flexible supporting substrate 31 and/or set the adjusting member 33 to be connected to any position of the flexible display panel 1 according to actual needs. It is not limited to which direction the adjusting member 33 specifically moves from the first position to the second position, and the details thereof are not repeated herein.

It can be understood by those skilled in the art that the adjusting members 33 move in different directions, so that the bending directions of the flexible display module 100 are different, and the bending curvature of the flexible display module 100 is related to the moving distance of the adjusting members 33, that is, when a user adjusts the flexible display module 100 from a flat state to a bent state, the larger the moving distance of the adjusting members 33 relative to the flexible support substrate 31 is, the larger the curvature of the flexible display module 100 is finally bent. Because the bending curvature of the flexible display module 100 is continuously changed during the movement of the adjusting member 33, that is, the connection between the flexible support substrate 31 and the adjusting member 33 may be in a bending state, and the adjusting member 33 moves along the plane of the flexible support substrate 31, the "plane" is not necessarily the plane of the flexible support substrate 31 in the flat state of the flexible display module 100, but is the plane of the tangent line at the connection between the adjusting member 33 and the flexible support substrate 31.

In the embodiment of the application, the adjusting part 33 is movably connected with the flexible supporting substrate 31, and meanwhile, the adjusting part 33 is fixedly connected with the flexible display panel 1, so that the relative position relationship between the flexible display panel 1 and the flexible supporting substrate 31 can be adjusted by changing the position relationship between the adjusting part 33 and the flexible supporting substrate 31, and the flexible display module 100 can be switched between the flat state and the bent state; meanwhile, the flexible display module 100 can be controlled to bend with different curvatures in different directions by controlling the moving direction and the moving distance of the adjusting piece 33, so that different requirements of users are met.

The second position includes a folded-in position and/or a folded-out position, the flexible display module 100 is located at the folded-in position, the display surface of the flexible display module 100 is in a concave state, the flexible display module 100 is located at the folded-out position, the display surface of the flexible display module 100 is in a convex state, and the display surface is a light emitting surface for the flexible display module 100 to display images and interact with a user. The flexible display module 100 is bent to be in a concave state or a convex state, so that the display viewing angle of the flexible display panel 1 can be increased.

Referring to fig. 3 and fig. 4, wherein the flexible display module 100 shown in fig. 3 is in a flat state, and the flexible display module 100 shown in fig. 4 is in a folded position. In some embodiments, the number of the adjusting members 33 is two, and the two adjusting members 33 are moved away from each other to the folded-in position, so that the flexible display panel 1 and the flexible support substrate 31 are bent in the light emitting direction away from the flexible display panel 1. Specifically, only one of the adjusting members 33 may be adjusted to move toward the other adjusting member 33, or both of the adjusting members 33 may be adjusted to move closer at the same time. Similarly, when the two adjusting parts 33 move away from each other to the inward-folding position, the distance between the joints of the flexible supporting substrate 31 and the two adjusting parts 33 is greater than the distance between the joints of the flexible display panel 1 and the two adjusting parts 33, and the adjusting parts 33 apply pressure to the flexible display panel 1, so that the flexible display panel 1 is bent, and the flexible supporting substrate 31 is driven to be bent.

Referring to fig. 5, the flexible display module 100 shown in fig. 5 is in the folded-in position. In another embodiment, the number of the adjusting members 33 is two, and the two adjusting members 33 approach each other and move to the folded-out position, so that the flexible display panel 1 and the flexible support substrate 31 are bent toward the light-emitting direction of the flexible display panel 1. Similarly, when the two adjusting members 33 approach each other and move to the folded-out position, the distance between the joints of the flexible supporting substrate 31 and the two adjusting members 33 is smaller than the distance between the joints of the flexible display panel 1 and the two adjusting members 33, and the adjusting members 33 apply pressure to the flexible supporting substrate 31, so that the flexible supporting substrate 31 bends and drives the flexible display panel 1 to bend.

The flexible display panel 1 may have a flat state, and a folded-in state and/or a folded-out state, that is, the same flexible display panel 1 may have the capability of being folded into the folded-in state and the folded-out state at the same time, or may have the capability of being folded into the folded-in state or the folded-out state only, and may be specifically realized by limiting the movement area of the adjusting member 33. In order to ensure that the flexible display panel 1 has a better display effect, the flexible display module 100 may also have a maximum bending angle by limiting the movable area of the adjusting member 33.

Further, two regulating parts 33 are connected with flexible display panel 1's relative both ends respectively to when making flexible display module 100 crooked, the relatively connection region that sets up is connected with two regulating parts 33 respectively in the flexible display panel 1, and the region between the connection region all can be crooked, improves flexible display panel 1 in the flexible area of bendable. Referring to fig. 6, in order to ensure that the two ends of the flexible display panel 1 are uniformly stressed when being bent, the adjusting element 33 may be a flat plate parallel to the bending line of the flexible display panel 1.

Referring to fig. 3 and 4 again, the adjusting element 33 includes a plurality of compensation plates 331, and the plurality of compensation plates 331 are sequentially stacked along a direction from the flexible display panel 1 to the flexible supporting substrate 31; one end of at least one of the plurality of compensation plates 331, which is away from the flexible display panel 1, is movably connected to an adjacent compensation plate 331 or the flexible support substrate 31. The adjacent compensation plates 331 can be fixedly connected by gluing, welding and the like, and the adjacent compensation plates 331 or the compensation plates 331 and the flexible support substrate 31 can be movably connected by a meshed rack, a meshed guide groove and the like. For example: when the number of the compensation plates 331 is 3, the compensation plates are a first compensation plate, a second compensation plate and a third compensation plate in sequence along the direction from the flexible display panel 1 to the flexible support substrate 31, wherein one side of the first compensation plate is fixedly connected with the flexible display panel 1, one side of the first compensation plate is movably connected with the second compensation plate, one side of the third compensation plate is movably connected with the second compensation plate, and one side of the third compensation plate is movably connected with the flexible support substrate 31. The second compensation plate may be moved such that the second compensation plate applies pressure to the flexible display panel 1 or the flexible support substrate 31, and the third compensation plate may also be moved to apply pressure to the flexible display panel 1 or the flexible support substrate 31. The matching manner of the compensation plates 331 can be various, and is not illustrated.

In order to ensure that the region where the flexible display panel 1 is connected to the adjusting member 33 can also be bent, so that a plurality of compensation plates 331 stacked in sequence can be provided, the sum of the moving distances of the compensation plates 331 can be moved relative to the flexible support substrate 31 at the connection position of the adjusting member 33 and the flexible display panel 1 by moving each compensation plate 331 in a small region.

Referring to fig. 3 and 4, in an embodiment, the number of the compensation plates 331 is two, two compensation plates 331 are fixedly connected, one compensation plate 331 is fixedly connected with the flexible display panel 1, and one compensation plate 331 is movably connected with the flexible support substrate 31. When the compensation plate 331 connected to the flexible support substrate 31 moves, an interaction force exists between the flexible support substrate 31 and the compensation plate 331, and meanwhile, since the compensation plate 331 is fixedly connected to the flexible display panel 1 through another compensation plate 331, a deformation which may be generated by the compensation plate 331 does not affect the fixed connection between the other compensation plate 331 and the flexible display panel 1, thereby ensuring the stability of the connection of the adjusting member 33 with the flexible display panel 1 as a whole. It will be understood by those skilled in the art that the number of the compensation plates 331 is greater than or equal to two, which has the above-mentioned effect of improving the stability of the connection of the adjustment member 33 with the flexible display panel 1 as a whole.

Further, the length of each compensation plate 331 is sequentially decreased in the direction from the flexible display panel 1 to the flexible support substrate 31 with the moving direction of the adjuster 33 as the length direction. By setting the lengths of the respective compensation plates 331 to be successively reduced, the length of the compensation plate 331 connected to the flexible display panel 1 is made sufficiently small to reduce the influence of the adjustment member 33 on the flexible display panel 1.

Referring to fig. 6, 7 and 8, the flexible display panel 1 further includes a driving assembly 5 connected to the adjusting member 33, and the adjusting member 33 can be driven to move by controlling the driving assembly 5, but in other embodiments, the user can also manually toggle the adjusting member 33 to move. In an embodiment, the driving assembly 5 includes a driving member 51 and a gear 53 connected to each other, the adjusting member 33 includes a main body portion 335 and a rack 333 engaged with the gear 53, the rack 333 is disposed on the main body portion 335, and the driving member 51 is configured to drive the gear 53 to rotate so as to drive the adjusting member 33 to move relative to the flexible support substrate 31. The driving member 51 may be a motor, the gear 53 is sleeved on an output shaft of the motor, the output shaft drives the gear 53 to rotate, and the gear 53 and the toothed strip 333 perform relative displacement, so that the adjusting member 33 and the flexible supporting substrate 31 perform relative displacement. It will be appreciated that the drive assembly 5 may also move the adjustment member 33 in other forms, for example, a linear motor is used to push the adjustment member 33 to move, and the description is omitted here.

Further, the flexible supporting substrate 31 is provided with a first mounting hole 332 corresponding to the rack 333, and the gear 53 is disposed in the first mounting hole 332, so that the gear 53 can be accommodated in the first mounting hole 332, thereby reducing the overall size of the flexible display module 100. Of course, the driving member 51 may be independently disposed outside the supporting member 3 and the flexible display panel 1 to prevent the driving member 51 from being pressed after the supporting member 3 and the flexible display panel 1 are bent.

In one embodiment, the driving member 51 is disposed in the first mounting hole 332, so as to reduce the overall size of the flexible display module 100. It can be understood that, after the driving member 51 is disposed in the first mounting hole 332, a certain space is left in the first mounting hole 332 to prevent the driving member 51 from rotating due to the driving member 51 being pressed by the side wall of the first mounting hole 332 when the flexible supporting substrate 31 is bent and the first mounting hole 332 is deformed. Further, the length direction of the driving member 51 is perpendicular to the moving direction of the adjusting member 33 to reduce the influence of the bending of the flexible support substrate 31 on the driving member 51.

In another embodiment, the flexible supporting substrate 31 further has a second mounting hole 334 spaced apart from the first mounting hole 332 and a communication hole 336 communicating the first mounting hole 332 and the second mounting hole 334, the driving member 51 is disposed in the second mounting hole 334, and the driving shaft of the driving member 51 passes through the communication hole 336 and is connected to the gear 53. That is, the gear 53 and the driving member 51 are received in different mounting holes, and the driving shaft passes through the communication hole 336, so that the communication hole 336 can limit and support the driving, which is beneficial to improving the stability of the driving assembly 5. Further, a bearing may be further provided in the communication hole 336, and the drive shaft is connected to the gear 53 through the bearing to reduce friction.

In an embodiment, the flexible display panel 1 further comprises a guide 7 and a guide groove 9, which are adapted to each other, one of the guide 7 and the guide groove 9 is disposed on the flexible support substrate 31, and the other is disposed on the adjusting member 33, and the adjusting member 33 is capable of moving along the guide 7. In the embodiment shown in fig. 7 and 8, the guide groove 9 is opened on the adjusting member 33, the guide member 7 is disposed on the flexible supporting substrate 31, and when the adjusting member 33 and the flexible supporting substrate 31 are relatively displaced, on one hand, the extending direction of the toothed strip 333 limits the moving direction of the adjusting member 33, and on the other hand, the guide member 7 and the guide groove 9 limit the moving direction of the adjusting member 33, so that the moving direction of the adjusting member 33 is more stable by disposing the guide member 7 and the guide groove 9.

The flexible display panel 1 comprises a flexible display panel 1 and a substrate layer 13 which are stacked, and the surface of the substrate layer 13 departing from the flexible display panel 1 is connected with the adjusting member 33. The display layer 11 includes a light emitting device, a pixel driving circuit, an encapsulation layer, and the like, and is used to realize a picture display, in which the light emitting device emits light from the display surface of the flexible display panel 1. The regulating member 33 is connected to the substrate layer 13 and protects the structures on the display layer 11.
