Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art can appreciate, the described embodiments can be modified in various different ways, without departing from the spirit or scope of the present disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

Fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present disclosure. As shown in fig. 1, the display device may include a support assembly 10, an adjustment assembly, a roller shaft 30, and a flexible display panel 40. The adjustment assembly is connected to the support assembly 10. The first end 411 of the flexible display panel 40 is fixed to the adjustment assembly. The flexible display panel 40 includes a display portion 41 and a roll portion 42. The display portion 41 is located between the first end 411 and the roller shaft 30. The winding portion 42 is connected to the display portion 41 and wound around the roller shaft 30.

The roller 30 moves relative to the support assembly 10 to deploy or stow the flexible display panel 40. The area of the display portion 41 increases or decreases during the process of expanding or collapsing the flexible display panel 40. When the flexible display panel 40 is unfolded, the length of the display portion 41 increases, and the area of the display portion 41 increases; when the flexible display panel 40 is collapsed, the length of the display portion 41 is reduced, and the area of the display portion 41 is reduced. The adjustment assembly is used to adjust the position of the first end 411 relative to the support assembly 10 during deployment or retraction of the flexible display panel 40 to maintain the display portion 41 flat. It is to be understood that, as shown in fig. 1, the "length" is a dimension in the width direction of the sheet.

In the related art, the roll shaft moves relative to the supporting component to unfold or pack up the flexible display panel, and the flexible display panel is unstable in stress, so that the flexible display panel is loose in tension, the display part is loose and sunken, or the display part is rebounded and arched, or the flexible display panel is plastically deformed to cause the deformation height, the flatness of the display part cannot be ensured, and the display effect is influenced.

In the display device of the embodiment of the present disclosure, the adjusting component may adjust the position of the first end 411 relative to the supporting component 10, so that, when the display portion 41 is sagged or arched due to tension relaxation during unfolding or folding the flexible display panel, the adjusting component may adjust the position of the first end 411 relative to the supporting component 10, so that the first end moves away from the roller shaft 30 to tighten the display portion, reduce the arching height of the display portion, and reduce the height of deformation caused by plastic deformation of the flexible display panel, so that the display portion is kept flat. When the display part has too much tension, the adjusting component can adjust the position of the first end part 411 relative to the supporting component 10, so that the first end part 411 moves towards the direction close to the roller shaft 30, the tension borne by the display part is reduced, and the flexible display panel is prevented from being damaged due to the too much tension.

In one embodiment, the flexible display panel may include a flexible Organic Light-Emitting Diode (OLED) display panel. It is to be understood that the flexible display panel is not limited to the flexible OLED display panel, and in other embodiments, the flexible display panel may include other types of flexible display panels.

According to the display device in the embodiment of the disclosure, in the process of unfolding or folding the flexible display panel, the adjusting assembly adjusts the position of the first end part relative to the supporting assembly, so that the display part can be kept flat, the display effect of the display part is improved, the flexible display panel can be prevented from being damaged due to overlarge tension, and the service life of the flexible display panel is prolonged.

For example, the support member 10 may be a support stand of a display device, and the support member 10 may remain motionless during the process of unfolding or folding the flexible display panel. The roller 30 may be moved relative to the support assembly 10 in a direction perpendicular to the axis of the roller 30 to deploy or stow the flexible display panel 40.

For example, the roller 30 may not move in a direction perpendicular to the axis of the roller 30, the support assembly 10 may be driven to move the support assembly 10 in a direction perpendicular to the axis of the roller 30, and the roller 30 may rotate to unfold or retract the flexible display panel 40.

In one embodiment, as shown in fig. 1, the adjustment assembly may include a first moving plate 21 and an adjustment mechanism 22. The adjusting mechanism 22 is connected to the support assembly 10, and the first moving plate 21 is connected to the adjusting mechanism 22. The first end 411 of the flexible display panel 40 is fixed to the first moving plate 21. The adjustment mechanism 22 is used to apply a force to the first moving plate 21 during the process of unfolding or folding the flexible display panel 40, so as to move the first moving plate 21 to adjust the position of the first end portion relative to the support assembly 10. For example, the adjustment mechanism 22 applies a force to the first moving plate 21, and may move the first moving plate 21 in a direction perpendicular to the roller shaft 30.

With this structure, the adjustment mechanism 22 can generate a pulling force on the display section 41 by the first moving plate 21. During the process of unfolding or folding the flexible display panel, when the display part is arched or collapsed, the adjusting mechanism 22 can adjust the position of the first moving plate 21, so as to adjust the pulling force on the display part 41, and the display part is stressed evenly and kept flat.

In one embodiment, the support assembly 10 may include a first support 11. The first moving plate 21 is slidably coupled to the first support 11. The first moving plate 21 is slidable on the first support 11 in a direction perpendicular to the roller shaft 30. Illustratively, the adjustment mechanism 22 applies a force to the first moving plate 21 to slide the first moving plate 21 on the first support.

With this structure, when the first moving plate 21 is moved by the adjusting mechanism 22, the first support 11 can limit the first moving plate 21, prevent the first moving plate 21 from being inclined in a direction parallel to the roller axis, and prevent the display portion 41 from being twisted.

In one embodiment, the first moving plate 21 may be provided with a sleeve hole, and the first support 11 is inserted into the sleeve hole, so that the first moving plate 21 is sleeved outside the first support 11. The first moving plate 21 is slidable along the first support 11.

Exemplarily, the first support 11 may be a circular optical axis. When first supporter 11 is circular optical axis, can set up two or more trepannings on the first fixed orifices 21, the quantity of first supporter 11 can equal with the quantity of trepanning to alternate in the trepanning one by one.

For example, the first support 11 may have a non-circular optical axis, and the shape of the sleeve hole of the first moving plate 21 may match the cross-sectional shape of the first support 11.

In one embodiment, one of the first support 11 and the first moving plate 21 may be provided with a sliding slot, and the other one of the first support and the first moving plate may be provided with a sliding block matching with the sliding slot, and the sliding block may slide in the sliding slot, so that the first moving plate 21 may slide on the first support 11.

In one embodiment, the adjustment assembly may further include a force-bearing plate 23, the force-bearing plate 23 being located on a side of the first moving plate 21 facing away from the first end. The support assembly 10 may also include a support plate 12 and a force-bearing plate 13. The first support 11 is fixed to the support plate 12. The bearing plate 13 is connected to the support plate 12 and is arranged opposite to the bearing plate 23. The adjustment mechanism 22 may be located between the force bearing plate 23 and the force bearing plate 13. The adjustment mechanism 22 may apply a force to the first moving plate 21 through the force receiving plate 23.

For example, the adjusting mechanism 22 may be fixed to the force bearing plate 13, and the adjusting mechanism 22 may apply a force to the force bearing plate 23 to adjust a distance between the force bearing plate 23 and the force bearing plate 13, so as to move the first moving plate 21.

With this structure, the adjustment mechanism 22 can apply a force to the force receiving plate 23 and further to the first moving plate 21. The bearing plate 13 and the stress plate 23 are oppositely arranged, so that the direction of the acting force applied to the stress plate 23 by the adjusting mechanism 22 can be perpendicular to the stress plate 23, and the adjusting efficiency of the adjusting mechanism 22 is improved.

In one embodiment, the adjusting mechanism 22 may include a telescopic mechanism for telescoping to apply a force to the first moving plate 21 during the expansion or contraction of the flexible display panel.

Illustratively, the telescoping mechanism may include a drive motor and a telescoping rod connected to the drive motor. The first moving plate 21 may be connected to a telescopic rod, for example, the force-bearing plate 23 is connected to a telescopic rod. A tension detecting device may be provided on the roller shaft 30, and the tension detecting device may detect the tension of the flexible display panel. When the tension detecting device detects that the tension of the flexible display panel is less than the first threshold, indicating that the display portion is collapsed or arched, the telescopic mechanism may adjust the first moving plate 21 to move in a direction away from the roller shaft 30 to tighten the display portion. When the tension detecting device detects that the tension of the flexible display panel is greater than the second threshold, it indicates that the tension of the display portion is too large, and the telescopic mechanism can adjust the first moving plate 21 to move towards the direction close to the roller shaft 30, so as to reduce the tension applied to the display portion. The second threshold is greater than the first threshold. It is understood that the specific values of the first threshold and the second threshold may be set as desired.

In one embodiment, the telescopic mechanism may include an elastic member 221, and the elastic member 221 is elastically deformed during the process of expanding or retracting the flexible display panel to adjust the force applied to the first moving plate 21. For example, the elastic member 221 is elastically deformed during the process of unfolding or folding the flexible display panel, and adjusts the force applied to the force-receiving plate 23, thereby moving the first moving plate in a direction perpendicular to the axis of the roller shaft 30.

For example, the force bearing plate 23 may be located on the side of the force bearing plate 13 facing away from the roller shaft 30, as shown in fig. 1. The elastic member 221 may include a compression spring. In the process of unfolding or folding the flexible display panel, when the display part collapses or arches, the pressure spring is stretched due to the reduction of the stress, the distance between the force bearing plate 13 and the force bearing plate 23 is increased, the force bearing plate 23 moves towards the direction far away from the roller shaft 30 to tighten the display part, so that the display part 41 is stressed in a balanced manner, and the display part 41 is kept flat. When the tension borne by the display part is overlarge, the pressure spring is compressed and shortened, the distance between the bearing plate 13 and the stress plate 23 is reduced, and the stress plate 22 moves towards the direction close to the roller shaft 30 to reduce the tension of the display part, so that the stress of the display part is balanced, and the flexible display panel is prevented from being damaged by pulling.

For example, the bearing plate may be located on a side of the bearing plate facing the roller shaft, and the elastic member may include a tension spring. In the process of unfolding or folding the flexible display panel, when the display part collapses or arches, the tension spring is shortened due to the reduction of the stress, so that the stress plate moves towards the direction far away from the roller shaft 30 to tighten the display part, the stress of the display part is balanced, and the display part is kept flat. When the tension borne by the display part is overlarge, the tension spring is stretched and extended, so that the stress plate moves towards the direction close to the roller shaft 30, the tension of the display part is reduced, the stress of the display part is balanced, and the flexible display panel is prevented from being damaged by pulling.

The number of the telescopic mechanisms may be set according to actual needs, for example, one or more telescopic mechanisms may be provided at regular intervals in the width direction of the display part so that the first moving plate is uniformly stressed in the width direction. It is understood that the width direction is a direction parallel to the axis of the roller shaft.

In one embodiment, as shown in fig. 1, the display device may further include a second support body 51 and a second moving plate 52. The second moving plate 52 is movable on the second support 51. The flexible display panel 40 may further include a hiding portion 43, the hiding portion 43 is connected to the winding portion 42, and the hiding portion 43 is connected to an end of the winding portion 42 away from the display portion. A second end 421 of the hidden portion 43 away from the winding portion 42 is fixed to the second moving plate 52. The second moving plate 52 moves on the second support 51 to increase or decrease the area of the display section 41 by the roller shaft 30.

The second moving plate 52 is moved on the second support 51 toward a direction approaching the roller shaft 30 so that the length of the hidden portion 42 is reduced and the area of the hidden portion 42 is reduced, and further so that the length of the display portion 41 is increased and the area of the display portion 41 is increased; the second moving plate 52 is moved on the second support 51 in a direction away from the roller shaft 30 so that the length of the hidden portion 42 is increased and the area of the hidden portion 42 is increased, and further, the length of the display portion 41 is decreased and the area of the display portion 41 is decreased. It is to be understood that "the length of the display portion" is a dimension of the display portion in the direction of the roller shaft at the first end portion, and "the length of the hidden portion" is a dimension of the hidden portion in the direction of the roller shaft at the second end portion.

In one embodiment, the flexible display panel may be wound on a roller, and the roller may be moved and rotated in a direction away from the first end to unfold the flexible display panel; the roller may move and rotate in a direction near the first end to retract the flexible display panel.

Fig. 2 is a schematic top view of a display device according to an embodiment of the disclosure, and fig. 2 only shows components related to a hidden portion. In one embodiment, as shown in fig. 2, the display device may further include a first driving mechanism 60. The number of the second supports 51 may include two, 51a and 51b, respectively. Both ends of the roller shaft 30 are connected to the corresponding second supports 51, respectively. The second support body 51 is provided with a thread structure on the periphery, and the second moving plate 52 is in screw transmission connection with the two second support bodies 51. The first drive mechanism 60 is used to drive the second support body 51 to rotate while driving the second support body 51 and the roller shaft 30 to move in a direction perpendicular to the axis of the roller shaft (vertical direction in fig. 2). The second moving plate 52 may move along the second support 51 with the rotation of the second support 51. Thus, the area of the display portion can be increased or decreased.

When the first driving mechanism 60 drives the second support 51 and the roller shaft 30 such that the roller shaft 30 moves in a direction away from the first end (a leftward direction in fig. 1 and an upward direction in fig. 2), the first driving mechanism may simultaneously drive the second support to rotate such that the second moving plate 52 moves in a direction closer to the roller shaft 30, the hidden portion area decreases, and the display portion area increases. When the first driving mechanism 60 drives the second support 51 and the roller shaft 30 such that the roller shaft 30 moves in a direction toward the first end (rightward in fig. 1 and downward in fig. 2), the first driving mechanism simultaneously drives the second support to rotate such that the second moving plate 52 moves in a direction away from the roller shaft 30, the hidden portion area increases, and the display portion area decreases.

By adopting the structure, the first driving mechanism can simultaneously realize the movement of the roller shaft and the movement of the second moving plate relative to the roller shaft, thereby simplifying the structure of the display device and reducing the cost.

In one embodiment, the roller may not rotate during the movement, and the flexible display panel slides along the surface of the roller during the expansion or contraction of the flexible display panel, that is, during the increase or decrease of the area of the display part.

In one embodiment, the roll shaft 30 is provided with a support base (not shown) at each end. The end part of the roll shaft can be rotatably connected with the corresponding supporting seat, and the supporting seat is connected with the second supporting body.

Fig. 3 is a schematic view illustrating a connection structure between a roller shaft and a second support according to an embodiment of the disclosure. In one embodiment, as shown in fig. 3, both ends of the roller shaft 30 are provided with first gears 31, respectively. One end of the second support body 51 near the roller shaft 30 is provided with a second gear 511. The first gear 31 and the second gear 511 are in meshing transmission connection. The first gear 31 and the second gear 511 may both be bevel gears. When the second support 51 rotates, the second gear 511 rotates along with the second support 51, thereby rotating the first gear 31 and rotating the roller shaft 30. Accordingly, the second support 51 rotates, and the first gear 31 is driven to rotate by the second gear 511, so that the roller shaft 30 rotates. The transmission ratio of the first gear and the second gear can be reasonably set, so that the rotating speed of the roller shaft is matched with the speed of unfolding or folding the flexible display panel.

With such a structure, the roller shaft 30 can rotate in the process of unfolding or folding the flexible display panel, so that the friction force between the flexible display panel and the roller shaft 30 can be reduced, the abrasion of the flexible display panel can be reduced, and the performance of the display device can be improved.

In one embodiment, as shown in fig. 2, the first drive mechanism 60 may include a first drive assembly 61 and a second drive assembly 62. The first driving unit 61 drives the second support 51a on the left side in fig. 2, and the second driving unit 62 drives the second support 51b on the right side in fig. 2. The first drive assembly 61 and the second drive assembly 62 move in synchronism. The first driving assembly may include a driving motor and a driving screw connected to the driving motor, the driving motor drives the driving screw to rotate, and the driving screw drives the second supporting body 51a to rotate and move. The second drive assembly may be identical in structure to the first drive assembly.

In one embodiment, the display device may further include a second driving mechanism. The roller shaft may be connected to a second drive mechanism. The second drive mechanism is for driving the roller shaft to move in a direction perpendicular to the axis of the roller shaft to increase or decrease the area of the display section. The second driving mechanism may employ a structure that is conventional in the art as long as the movement of the driving roller shaft to increase or decrease the area of the display section can be achieved.

In one embodiment, the display device further comprises supporting seats at both ends of the roller shaft, the roller shaft being rotatably connected to the supporting seats, and the supporting seats being connected to the second driving mechanism.

In one embodiment, the display device may further include a third driving mechanism, the number of the second supporting bodies may include two, two ends of the roller shaft are respectively connected to the corresponding second supporting bodies, the second supporting bodies are connected to the third driving mechanism, and the third driving mechanism is configured to drive the second supporting bodies and the roller shaft to move so as to increase or decrease the area of the display portion. The third driving mechanism may employ a structure that is conventional in the art as long as it can achieve driving the second support body and the roller shaft to move to increase or decrease the area of the display section.

In one embodiment, the display device may further include a fourth driving mechanism, wherein the second moving plate is in spiral transmission connection with the second support, and the fourth driving mechanism is configured to drive the second support to rotate so as to move the second moving plate along the second support. The fourth driving mechanism may adopt a structure conventional in the art as long as it can drive the second support to rotate so as to move the second moving plate along the second support.

In one embodiment, the third driving mechanism is used for driving the second supporting body and the roller shaft to move. The number of the second support bodies comprises two, and the second moving plate is in spiral transmission connection with the two second support bodies. And two ends of the roll shaft are respectively provided with a first gear. One end of the second supporting body, which is close to the roll shaft, is provided with a second gear, and the first gear and the corresponding second gear are in meshing transmission. The display device may further include a fifth driving mechanism for driving the roller shaft to rotate. The roller shaft rotates, and the first gear drives the second gear to rotate so as to rotate the second supporting body. The second support body rotates to drive the second moving plate to move relative to the second support body. Thus, the area of the display portion is increased or decreased.

The above exemplarily illustrates the movement of the roller shaft and the movement of the second moving plate with respect to the roller shaft. It is to be understood that, in order to unfold or fold up the flexible display panel, the above roller movement manner and the second roller movement manner may be arbitrarily combined as long as the unfolding or folding up of the flexible display panel to increase or decrease the area of the display portion can be achieved.

In one embodiment, as shown in fig. 1, the first end of the flexible display panel 40 is fixed to the first moving plate 21 by a fixing adhesive. Illustratively, in a direction of the first end 411 parallel to the roller shaft, fixing glue is uniformly disposed, so that the first end can be uniformly fixed to the first moving plate 21.

In one embodiment, the second end of the flexible display panel 40 is fixed to the second moving plate 52 by a fixing adhesive. Illustratively, the fixing glue is uniformly disposed in a direction of the second end portion parallel to the roller shaft, so that the second end portion can be uniformly fixed to the second moving plate 52. In such a way, the second end part can be prevented from warping, and the second end part and the shell of the display device can be prevented from being scratched.

In one embodiment, the securing glue may comprise a pop-top glue.

In one embodiment, as shown in fig. 1, the supporting assembly may further include a shielding plate 14, the shielding plate 14 being located at a side of the hiding portion 43 facing away from the display portion 41 to shield the second end 421.
