Description
Technical Field
The application relates to the technical field of display, in particular to a flexible display assembly, a flexible display device and flexible display equipment.
Background
Compared with a display screen in a folding form, the flexible display screen in a curling form can have a larger display area when the screen is unfolded, and has smaller volume and better portability after the screen is rolled.
Crimping of flexible display screens is typically accomplished by securing the roll-up head end of the flexible display screen to a crimping shaft, and the roll-up tail end is wound around the crimping shaft. However, as the winding operation proceeds, the stress of the flexible display screen increases, the flexible display screen is less likely to curl, and the stress difference between the regions of the flexible display screen increases, thereby causing easy separation and deformation between the film layers.
Disclosure of Invention
Accordingly, it is necessary to provide a flexible display module, a flexible display device, and a flexible display apparatus capable of avoiding separation and deformation between film layers.
According to one aspect of the present application, there is provided a flexible display assembly having a winding head end and a winding tail end disposed opposite to each other, the winding tail end being wound outside the winding head end, the flexible display assembly comprising:
the flexible display screen is provided with a display surface and a back surface which are opposite; and

In the flexible display assembly, the thickness of the flexible support plate is gradually reduced in the winding process of the flexible display assembly, so that the flexible support plate is easier to wind up from the later stage of winding, the stress of the flexible display assembly near the tail end of winding is reduced, and the stress of the flexible display assembly near the head end of winding is balanced by increasing the stress of the flexible display assembly near the head end of winding due to thicker flexible support plate. Therefore, the flexible display assembly is easier to curl, the curling experience is improved, and meanwhile separation and deformation between film layers caused by overlarge difference of stress in each area are avoided, so that the display effect of the flexible display assembly is good.
In an embodiment, the flexible display assembly further comprises a deformation member, wherein the deformation member is arranged between the flexible display screen and the flexible support plate;
the deformation piece can generate deformation when the winding tail end is wound on the outer side of the winding head end, and can recover deformation when the winding tail end is unfolded relative to the winding head end, so that the surface of the flexible support plate, deviating from the flexible display screen, is parallel to the flexible display screen. The flexible display assembly may be caused to be presented to a user in a flattened state when deployed.
In one embodiment, the deforming member is capable of storing energy by deformation when the tail end of the coil is wound around the head end of the coil, and releasing energy by recovering the deformation when the tail end of the coil is unwound from the head end of the coil. No additional components are required to cause the deformation member to provide a force to the flexible support plate that keeps it parallel to the flexible display screen on a side surface facing away from the flexible display screen.
In one embodiment, the deforming member is capable of being compressed when the tail end is wound around the head end and stretched when the tail end is unwound from the head end. The compression will cause a corresponding reduction in the thickness of the deformation, so that the stress near the tail end portion of the winding will not increase.
In an embodiment, the deformation member has a fold in a direction of the flexible display screen directed towards the flexible support plate. The folded deformation form occupies small space, and the deformation is stable and reliable.
In one embodiment, the deforming member has a deforming cavity. The deformation cavity has simple structure, high deformation response speed and light weight.
In one embodiment, the deformation member is further provided with a vent hole, and the vent hole is communicated with the deformation cavity and the outside of the deformation member;
the vent hole is arranged on one side end face of the deformation piece, which is close to the tail end of the winding. The volume change speed of the deformation cavity can be accelerated, and the deformation of the deformation piece is facilitated.
In an embodiment, when the winding tail end is unwound relative to the winding head end, the thickness of the deformation member gradually increases from the winding head end to the winding tail end, and a side surface of the deformation member facing the flexible support plate is wedged with a side surface of the flexible support plate facing the deformation member. The shape of the deformation piece can be matched with the shape of the flexible supporting plate, so that when the flexible display screen is curled, the stress between the flexible supporting plate and the flexible display screen can be continuously and stably buffered, and when the flexible display screen is unfolded, the surface of one side of the flexible supporting plate, which is away from the flexible display screen, is stably and reliably leveled with the flexible display screen.
In one embodiment, the flexible support plate is made of stainless steel. The stainless steel structure is stable, and the supporting and deforming effects are good.

As shown in fig. 1, the folding area FR of the foldable display screen 1 is generally disposed at the middle portion of the display screen 1, so that the area of the display screen 1 is reduced after folding, but the display screen 1 has a larger volume, and the flexible display screen 2 which can be curled, as shown in fig. 2, can be fixed to the winding head end 2a of the flexible display screen 2 by the curling shaft 3, and the winding tail end 2b can be wound around the curling shaft, so that the whole flexible display screen 2 is finally columnar, and thus the volume is further reduced.
While the flexible display screen that can be curled has a smaller volume, the stress of the flexible display screen is correspondingly increased, and it is most obvious that when the winding motion is performed to the rear, as the curling radius of the flexible display screen 2 increases, the stress of the flexible display screen 2 will be greater, and the film layers will be pressed against each other, so that separation (peeling) and deformation between the film layers are easily caused, and poor display is caused.
In the conventional technology, the stress caused by curling is generally reduced by reducing the thickness of the flexible display screen, and specifically, the stress can be reduced by reducing the number of film layers or reducing the thickness of the film layers, for example, reducing the thickness of a flexible cover plate, a Polarizer (POL) or a flexible support plate.
However, the inventor researches that the conventional technology still has the problems of separation and deformation between film layers caused by large stress difference of each area of the flexible display screen although the stress in curling is reduced.
In order to solve the above-mentioned problem, this application embodiment provides a flexible display assembly, through setting up the thickness of the flexible backup pad that supports flexible display screen to reduce gradually from winding head end to winding tail end, so that flexible display assembly is in the winding process, the thickness of flexible backup pad is less more behind, the stress of flexible display screen is less more, and the stress difference in each region is little for stress equilibrium has avoided separation and deformation between each rete, makes flexible display screen display effect good.
FIG. 3 is a schematic cross-sectional view of a flexible display assembly according to an embodiment of the present application in an expanded state; fig. 4 shows a schematic view of an expanded cross-sectional structure of the flexible display assembly shown in fig. 3 in a rolled state.
Referring to the drawings, a flexible display assembly 100 in at least one embodiment of the present application includes a flexible display 10 and a flexible support plate 20, wherein the flexible display 10 has a display surface and a back surface opposite to each other, and the flexible support plate 20 is disposed on the back surface to support the flexible display 10. It will be appreciated that the display surface is the side surface of the flexible display screen 10 on which images can be displayed. The flexible display assembly 100 disclosed in the embodiment of the application can be applied to the fields of mobile phone terminals, bionic electrons, electronic skins, wearable equipment, vehicle-mounted equipment, internet of things equipment, artificial intelligent equipment and the like. For example, the above can be applied to digital devices such as mobile phones, tablet computers, palm computers, ipods, smart watches, and the like. The following is a one-to-one description of the various portions of the flexible display assembly 100.
The flexible display panel 10 may be an organic light emitting diode (Organic Light Emitting Diode, OLED) display panel, a liquid crystal (Liquid Crystal Display, LCD) display panel, or electronic paper having bending deformation capability.
Taking an organic light emitting diode display panel as an example, the flexible display panel 10 includes a substrate, a thin film transistor (Thin Film Transistor, TFT) layer, an anode, a display light emitting layer, a cathode, an encapsulation layer, and the like, which are sequentially stacked. Further, the flexible display assembly 100 further includes a polarizer 30 (POL), a Touch panel 40 (TP), and a flexible cover 50 sequentially stacked over the display surface of the flexible display panel 10, and the flexible display panel 10 and the polarizer 30, the polarizer 30 and the Touch panel 40, and the Touch panel 40 and the flexible cover 50 may be bonded by an adhesive layer 60. It should be noted that the flexible display panel 10, the polarizer 30, the touch screen 40, and the flexible cover 50 are combined to form the flexible display module 70.
The flexible display assembly 100 has a winding head end 110 and a winding tail end 120 disposed opposite to each other, and the winding tail end 120 is wound outside the winding head end 110. Specifically, a winding shaft may be disposed at the winding head 110, and the winding tail 120 may be wound around the winding shaft during the rotation of the winding shaft, so as to wind the flexible display 10 and the flexible support plate 20. Of course, when the curl axis rotates in a direction opposite to the winding direction, the winding tail 120 can be unwound relative to the winding head 110, thereby achieving the unwinding of the flexible display 10 and the flexible support plate 20. In other embodiments, the winding tail 120 may be wound around the winding shaft while the winding shaft is stationary.
The flexible support plate 20 can keep synchronous with the flexible display screen 10 when the flexible display screen 10 is wound and unwound, and the flexible display screen 10 can be supported by the flexible support plate 20, so that the possibility of warping of the flexible display screen 10 can be reduced, and the flatness of the flexible display screen 10 can be improved. In particular, in the embodiment of the present application, the flexible support plate 20 is made of stainless steel, and in other embodiments, may be made of an alloy material, such as a titanium alloy, without limitation.
The thickness of the flexible support plate 20 gradually decreases from the winding head end 110 to the winding tail end 120.
In this way, during the winding process of the flexible display assembly 100, since the thickness of the flexible support plate 20 is gradually reduced, the winding of the flexible support plate 20 is easier to be performed further to the later stage of winding, the stress of the flexible display assembly 100 near the winding tail end 120 is reduced, and the stress of the flexible display assembly 100 near the winding head end 110 is balanced by increasing the stress of the flexible display assembly 100 near the winding head end 110 due to the thicker flexible support plate 20. Therefore, the flexible display assembly 100 of the present application not only is easier to curl, and improves the curling experience, but also avoids the separation and deformation between the film layers caused by overlarge difference of stress in each area, so that the display effect of the flexible display assembly 10 is good.
In some embodiments, the flexible display assembly 100 further includes a leveling member 80, the leveling member 80 being disposed between the flexible display screen 10 and the flexible support plate 20, the leveling member 80 being capable of providing a force that maintains the surface of the flexible support plate 20 facing away from the flexible display screen 10 parallel to the flexible display screen 10 when the tail end 120 of the roll is unwound relative to the head end 110 of the roll. In this manner, the flexible display assembly 100 may be presented to a user in a flat state as the tail end 110 of the roll is unwound from the head end 120 of the roll.
Further, the leveling member 80 includes a deformation member 81, where the deformation member 81 can deform when the winding tail 120 is wound around the winding head 110, and can recover the deformation when the winding tail 120 is unwound from the winding head 110, so that the surface of the flexible support plate 20 facing away from the flexible display 10 is parallel to the flexible display 10. In this way, the deformation member 81 can be made to change in shape in response to the winding operation of the flexible display 10 and the flexible support 20, so that the influence of the holding member 80 on the stress of the flexible display assembly 100 during winding can be reduced. Specifically, the deformation member 81 can be deformed by being pressed by the flexible display screen 10 and the flexible support plate 20 when the winding tail end 120 is wound around the fixed end 110.
Further, the deforming member 81 can store energy by deformation when the winding tail 120 is wound around the winding head 110, and release energy by recovering deformation when the winding tail 120 is unwound from the winding head 110. In this manner, the deformation member 81 provides the flexible support plate 20 with a force that keeps it parallel to the flexible display screen 10 on a side surface facing away from the flexible display screen 10 without using an additional member, simplifying the overall structure of the flexible display assembly 100. Specifically, the deforming member 81 is an elastically deforming member. Such as compression springs, elastic silicone or elastic rubber, etc.
Specifically, the deforming member 81 can be compressed when the winding tail 120 is wound around the winding head 110, and can recover deformation when the winding tail 120 is unwound from the winding head 110. When the deformation member 81 itself is capable of accumulating energy, the compression energy accumulating manner is simpler, and the compression can correspondingly reduce the thickness of the deformation member 81, so that the stress near the winding tail end 120 is not increased in the later winding period of the flexible display assembly 100.
Illustratively, the deforming member 81 has a folded portion 811 in a direction in which the flexible display screen 10 is directed toward the flexible support plate 20. Thus, when the winding tail 120 is curled around the winding head 110, the folding portion 811 may be in a folded state so that the deformation portion 80 is compressed, and when the winding tail 120 is unfolded with respect to the winding head 110, the folding portion 811 may be in an unfolded state so that the deformation member 81 is restored to shape. The folded deformation form occupies small space, and the deformation is stable and reliable.
It is noted that the folded portion 811 may be used as a portion of the deformation portion 80 that stores energy and release capacity.
In other embodiments, deformation 81 can also be controlled to provide a force that maintains flexible support panel 20 parallel to flexible display screen 10 on a side surface facing away from flexible display screen 10. Specifically, the deforming member 81 can be compressed when the winding tail 120 is curled with respect to the winding head 110, and recover deformation by an external force when the winding tail 120 is unwound with respect to the winding head 110.
In some embodiments, deforming member 81 has deforming cavity 812. The deformation member 81 is deformed by changing the volume of the deformation chamber 812. The deformation cavity 812 has a simple structure, a rapid deformation response speed, and a light weight.
Further, as shown in fig. 5, the deforming member 81 is further provided with a vent hole 813, and the vent hole 813 communicates the deforming cavity 812 with the outside of the deforming member 81. In this way, when the winding tail 120 is wound around the winding head 110, the gas in the deformation chamber 812 is discharged to the outside through the vent hole 813, so that the deformation member 81 is deformed by reducing the volume of the deformation chamber 812, and when the winding tail 120 is unwound from the winding head 110, the gas from the outside is sucked into the deformation chamber 812 through the vent hole 813, so that the deformation member 81 is restored to the deformed shape by restoring the volume of the deformation chamber 812.
Further, the vent hole 813 is opened on a side end surface of the deforming member 81 near the winding tail end 120. The winding tail 120 is the latest winding position and the earliest unwinding position, so that the vent hole 813 is arranged at the position, thereby accelerating the volume change speed of the deformation cavity 812 and facilitating the deformation of the deformation piece 81. Of course, in other embodiments, the vent hole 813 may be provided at the side of the deforming member 81 adjacent to the winding tail 120, which is not limited herein.
In some embodiments, when the winding tail 120 is unwound from the winding head 110, the thickness of the deformation member 81 gradually increases from the winding head 110 to the winding tail 120, and a side surface of the deformation member 81 facing the flexible support plate 20 is wedged with a side surface of the flexible support plate 20 facing the deformation member 81. In this way, the shape of the deformation member 81 can be matched with the shape of the flexible support plate 20, so that when the flexible display assembly 100 is curled, the stress between the flexible support plate 20 and the flexible display screen 10 can be continuously and stably buffered, and when the flexible display assembly 100 is unfolded, the surface of one side of the flexible support plate 20 facing away from the flexible display screen 10 is stably and reliably leveled with the flexible display screen 10. For example, in the embodiment of the present application, the cross-sectional shape of the flexible support plate 20 is wedge-shaped, and the cross-sectional shape of the corresponding deforming member 81 is also wedge-shaped.
Referring to fig. 3 and 4 again, in some embodiments, the deformation member 81 is tightly attached to the flexible display 10 and the flexible supporting plate 20 from the winding head 110 to the winding tail 120, respectively. In this way, the deformation member 81 can be made more reliable in receiving and transmitting the force between the flexible display screen 10 and the flexible support plate 20. As shown in fig. 6, in the preferred embodiment of the present application, the deformation member 81 includes an elastically deformable housing 814, the elastically deformable housing 814 is tightly attached to the flexible display 10 and the flexible support plate 20 from the winding head end 110 to the winding tail end 120, the elastically deformable housing 814 has a deformation cavity 812 and is provided with a vent hole 813, the elastically deformable housing 814 has a folded portion 811 along the direction of the flexible display 10 pointing to the flexible support plate 20, and the folded portion 811 is disposed along the circumferential direction of the deformed housing 814.
Based on the same inventive concept, the present application also provides a flexible display device including the flexible display assembly 100 of the above embodiment and a winding shaft fixed to the winding head 110 of the flexible display assembly 100.
Based on the same inventive concept, the present application also provides a flexible display apparatus including the flexible display device in the above embodiment. Specifically, the flexible display device may be a digital device such as a mobile phone, a tablet, a palm computer, an ipod, a smart watch, and the like.
Where the terms "comprising," "having," and "including" are used herein, another component may also be added unless explicitly defined as such, e.g., "consisting of … …," etc. Unless mentioned to the contrary, singular terms may include plural and are not to be construed as being one in number.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples merely represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
