Abstract
Description
Technical Field
[0001] This invention relates to the field of display technology, and more specifically, to a display device. Background Technology
[0002] With economic development, especially the development of the automobile industry, the number of cars in society is increasing. As people's living standards improve, using cars as a means of transportation has become very common. Consumers are also placing higher demands on vehicle configurations and paying more attention to the multimedia experience when purchasing cars.
[0003] The in-vehicle central control display screen is the main device for outputting multimedia such as images and videos. Currently, in-vehicle displays are trending towards curved screens. Curved screens increase the viewing angle; since the human eyeball is convex and curved, the curvature of a curved screen ensures a more even distance between the eyes, resulting in a better sensory experience. Curved screens also offer superior display effects compared to flat screens. Furthermore, there is a growing trend towards larger screen sizes for in-vehicle displays, with large curved screens providing a better riding experience for passengers. Moreover, in-vehicle displays are expected to not only display parameters related to vehicle operation for the driver but also simultaneously provide entertainment for other passengers.
[0004] However, existing in-vehicle large screen displays cannot dynamically adjust their curvature. They are either fixed flat screens or curved screens with a fixed curvature. The fixed screen curvature cannot adapt to changes in the viewer's position and cannot meet consumers' requirements for humanization and intelligence in vehicles.
[0005] Therefore, providing a display device that can not only flexibly switch between flat and curved surfaces, but also dynamically adjust the curvature according to different application scenarios to adapt to changing display scenarios and viewers in different positions, in order to present the best display effect, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0006] In view of this, the present invention provides a display device to solve the problem that the curvature of the curved screen in the prior art is fixed and cannot adapt to changes in the viewer's position and the ever-changing display scenarios.
[0007] This invention discloses a display device, comprising: a flexible display module and a propulsion component, wherein the propulsion component is disposed on the side of the flexible display module opposite to the light-emitting surface; the display device includes at least a first state and a second state; in the first state, the propulsion component is not in contact with the side of the flexible display module opposite to the light-emitting surface, and the flexible display module is in a planar state; in the second state, the propulsion component is in contact with the side of the flexible display module opposite to the light-emitting surface, and the flexible display module is in a bent state.
[0008] Compared with the prior art, the display device provided by the present invention achieves at least the following beneficial effects:
[0009] The display device provided by this invention includes a flexible display module and a propulsion component. The propulsion component, used to change the planar state and curved state of the flexible display module, is disposed on the non-light-emitting side of the flexible display module. The display device includes at least a first state and a second state, both of which can be understood as the usage states of the display device. In the first state, the propulsion component does not contact the side of the flexible display module away from the light-emitting surface. At this time, the flexible display module maintains its original planar state, making the display device present a flat, straight display. When it is necessary to switch to the second state, the propulsion component can be advanced towards the flexible display module. Eventually, the propulsion component gradually contacts the side of the flexible display module away from the light-emitting surface. After the propulsion component contacts the flexible display module on the non-light-emitting side, it can change the shape of the flexible display module, making the flexible display module curved, and the display device presents a curved surface display. Furthermore, as the propulsion component moves closer to the flexible display module, the degree of shape change in the flexible display module can be controlled by the specific distance the propulsion component travels. For example, the closer the propulsion component is to the flexible display module, the greater the degree of bending of the flexible display module. This allows for both shape adjustment of the flexible display module and dynamic adjustment of its curvature in the second state, making the curvature (degree of bending) of the display device in the second state flexible and variable. When the display device of this invention is applied to in-vehicle displays, it is not only suitable for large-size, large-screen in-vehicle displays, which helps to bring a better riding experience to passengers in the vehicle, but it can also present different forms according to different application scenarios to ensure display effects. By determining the current application scenario of the in-vehicle display, the form of the display device is dynamically adjusted to ensure that the in-vehicle display device presents the best display effect, which helps to improve the user satisfaction of passengers in the vehicle.
[0010] Of course, any product implementing this invention need not necessarily achieve all of the technical effects described above at the same time.
[0011] Other features and advantages of the invention will become clear from the following detailed description of exemplary embodiments of the invention with reference to the accompanying drawings. Attached Figure Description

Therefore, this invention is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this invention can be combined with each other without contradiction.
[0047] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0048] Please refer to the reference. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a display device in a first state according to an embodiment of the present invention. Figure 2 This is a schematic diagram of a display device in a second state provided in an embodiment of the present invention. The display device 000 provided in this embodiment includes: a flexible display module 10 and a pushing component 20. The pushing component 20 is disposed on the side of the flexible display module 10 away from the light-emitting surface.
[0049] The display device 000 includes at least a first state and a second state;
[0050] In the first state, the propulsion component 20 does not contact the side of the flexible display module 10 that is away from the light-emitting surface, and the flexible display module 10 is in a planar state.
[0051] In the second state, the propulsion component 20 contacts the side of the flexible display module 10 away from the light-emitting surface, and the flexible display module 10 is in a bent state.
[0052] Specifically, the display device 000 provided in this embodiment includes a flexible display module 10 and a propulsion component 20, wherein the propulsion component 20 is used to change the state of the flexible display module 10. The flexible display module 10 may include a flexible organic light-emitting diode display panel, a support film layer located on the side of the display panel away from the light-emitting surface, and a flexible cover plate (not shown in the figure) located on the side of the display panel away from the light-emitting surface. That is, when the propulsion component 20 contacts the side of the flexible display module 10 away from the light-emitting surface, it contacts the support film layer of the flexible display module 10 and will not damage the display panel. It is understood that this embodiment does not describe the structure of the flexible display module 10 in detail, and the structure of the flexible display module in related technologies can be referred to for understanding. In this embodiment and subsequent embodiments, the light-emitting surface 10E of the flexible display module 10 can be understood as one side surface of the display screen of the flexible display module 10. The side of the flexible display module 10 opposite to the light-emitting surface 10E can be understood as the side surface opposite to the light-emitting surface 10E of the display screen of the flexible display module 10. Since the organic light-emitting diode display panel included in the flexible display module 10 is a self-emissive display panel, the side of the flexible display module 10 opposite to the light-emitting surface 10E does not need to play a role in emitting or transmitting light. Therefore, other structures of the display device 000 (such as the push component 20 being disposed on the side of the flexible display module 10 opposite to the light-emitting surface 10E in this embodiment) can be provided on the side of the flexible display module 10 opposite to the light-emitting surface 10E. It should be noted that in the figures of this embodiment and subsequent embodiments, the backlight surface 10F represents the side of the flexible display module 10 opposite to the light-emitting surface 10E, and will not be explained further in subsequent embodiments.
[0053] In this embodiment, the propulsion component 20 for changing the planar state and the curved state of the flexible display module 10 is disposed on one side of the backlight surface 10F of the flexible display module 10. The display device 000 includes at least a first state and a second state. Both the first state and the second state can be understood as the usage state of the display device 000. Specifically, the display device 000 in the first state is in a planar state, that is, the flexible display module 10 is a flat display screen at this time. The display device 000 in the second state is in a curved state, that is, the flexible display module 10 is a curved display screen at this time. The switching between the first state and the second state can be controlled by the propulsion component 20 disposed on one side of the backlight surface 10F of the flexible display module 10. In the first state, the pushing component 20 does not contact the side of the flexible display module 10 away from the light-emitting surface. At this time, the flexible display module 10 remains in its original planar state, so that the display device 000 presents a flat, straight display. When it is necessary to switch to the second state, the pushing component 20 can be pushed towards the flexible display module 10. Eventually, the pushing component 20 gradually contacts the side of the flexible display module 10 away from the light-emitting surface. After the pushing component 20 contacts the flexible display module 10 on the backlight surface 10F side, it can change the shape of the flexible display module 10, so that the flexible display module 10 is in a curved state, and the display device 000 presents a curved surface display. Furthermore, as the propulsion component 20 moves closer to the flexible display module 10, the degree of shape change of the flexible display module 10 can be controlled by the specific travel distance of the propulsion component 20. For example, the closer the propulsion component 20 is to the backlight surface 10F of the flexible display module 10, the greater the degree of bending of the flexible display module 10. This allows for the adjustment of the shape of the flexible display module 10 while also dynamically adjusting the curvature of the flexible display module 10 in the second state, making the curvature (degree of bending) of the display device 000 in the second state flexible and variable.
[0054] It is understood that the figures in this embodiment are merely illustrative of the shape of the propulsion component 20. In specific implementation, the shape and connection structure of the propulsion component 20 are not specifically limited. For example, the propulsion component 20 may include a propulsion block structure for forming the flexible display module 10 into a curved state, and may also include a structure for controlling the forward and backward movement of the propulsion block, etc. For details, please refer to the explanations of the following embodiments. The propulsion component 20 only needs to satisfy the requirement that the degree of shape change of the flexible display module 10 can be controlled by the travel distance during the process of approaching the flexible display module 10.
[0055] like Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of the display device provided in this embodiment of the invention when applied to the field of vehicle display in a first state (it can be understood that, in order to clearly illustrate the structure of this embodiment, Figure 3(This can be understood as a top-down structural diagram of the vehicle). When the display device 000 in this embodiment is applied to the field of in-vehicle displays, the size of the flexible display module 10 can be relatively large. For example, if the display device 000 is located in the area of the entire center console M, the lateral dimension of the flexible display module 10 can cover the area where the driver A and the front passenger B are located. A large-size in-vehicle display is beneficial to providing a better riding experience for passengers in the vehicle. The propulsion component 20 can be hidden on one side of the backlight surface 10F of the flexible display module 10, or a cavity (not shown in the figure) can be provided on one side of the backlight surface of the flexible display module 10 for placing the propulsion component 20, so as to ensure the aesthetics and safety of the display device 000 in the vehicle. In some other alternative embodiments, the display device 000 may also be designed to be completely hidden inside the center console M. For example, when the display device 000 is not in use, it can be hidden inside the cavity of the center console M in the vehicle. When it is needed for viewing, the display device 000 can be raised from the cavity of the center console M using a lifting mechanism or other device for viewing by the people in the vehicle. This embodiment will not be described in detail here, but can be understood by referring to the following embodiments.
[0056] like Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the display device provided in this embodiment of the invention when applied in the field of vehicle display, in a second state. Figure 5 This is another structural schematic diagram of the display device provided in this embodiment of the invention when applied to the field of automotive displays, in a second state (it is understood that this is a schematic diagram for the purpose of clearly illustrating the structure of this embodiment). Figure 4 and Figure 5 The propulsion component 20 has been filled with transparency. Figure 4 and Figure 5 This can be understood as a top-down structural diagram of the vehicle. Figure 4 and Figure 5 The dotted line indicating the propulsion component 20 can be understood as its position in the first state, and the solid line indicating the propulsion component 20 can be understood as its position in the second state. When the display device 000 of this embodiment is applied to the field of automotive displays, in the second state, the propulsion component 20 can begin to perform a driving operation, that is, the propulsion component 20 can be pushed towards the flexible display module 10. When the propulsion component 20 contacts the backlight surface 10F side of the flexible display module 10, the shape of the flexible display module 10 can gradually change from the original planar state to a curved state. The degree of shape change of the flexible display module 10 can be controlled by the travel distance during the process of approaching the flexible display module 10. For example, when the ambient light outside the vehicle becomes brighter and the brightness of the side windows affects the viewing experience of the people inside the vehicle, the propulsion component 20 can be used to change the shape of the flexible display module 10 from a planar state to a curved state. Figure 3 The planar shape is switched to, for example Figure 4 The flexible display module 10 is shown in a slightly curved state; however, when the ambient light outside the vehicle becomes brighter or the information displayed by the display device 000 needs to maintain privacy, the flexible display module 10 can be further pushed by the pushing component 20 to switch its shape to the form shown. Figure 5 The greater degree of bending shown, Figure 5 The bending degree of the flexible display module 10 shown is greater than Figure 4 The degree of curvature of the flexible display module 10 shown helps to ensure the privacy of the displayed image on the display device 000. Alternatively, in other application scenarios, the flexible display module 10 can be made to exhibit other curved states by changing the different pushing areas of the flexible display module 10 through the pushing component 20. This embodiment is not limited to these specific cases.
[0057] When the display device 000 of this embodiment is applied to vehicle display, it is not only suitable for large-size vehicle displays, which is beneficial to bringing a better riding experience to passengers in the vehicle, but also can present different forms according to different application scenarios to ensure display effect. By determining the current application scenario of the vehicle display, the form of the display device 000 is dynamically adjusted so that the vehicle display device 000 presents the best display effect and better improves the user satisfaction of passengers in the vehicle.
[0058] It should be noted that the figures in this embodiment are merely examples illustrating the structure of the flexible display module 10. In actual implementation, the flexible display module 10 may include a display panel, a cover plate, etc. This embodiment will not elaborate on these details. For specific understanding, please refer to the module structure of flexible display devices in related technologies.
[0059] In some alternative embodiments, please refer to the references. Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of another structure of the display device provided in the first state according to an embodiment of the present invention. Figure 7 This is a schematic diagram of another structure of the display device provided in the second state according to an embodiment of the present invention. In this embodiment, the propulsion component 20 includes a propulsion block 201 and at least two propellers 202; the propellers 202 are disposed on the side of the propulsion block 201 away from the flexible display module 10.
[0060] Along the first direction X, at least two thrusters 202 are disposed on opposite sides of the thrust block 201;
[0061] In the second state, the flexible display module 10 is bent in the first direction X.
[0062] This embodiment explains the structure of the propulsion assembly 20 used to change the planar state and bending state of the flexible display module 10. It may include a propulsion block 201, with one side surface of the propulsion block 201 facing the backlight surface 10F of the flexible display module 10. The other side surface of the propulsion block 201 is provided with at least one propeller 202 for controlling the forward and backward movement of the propulsion block 201. The propellers 202 are located on the side of the propulsion block 201 away from the flexible display module 10, and at least two propellers 202 are arranged on opposite sides of the propulsion block 201 along a first direction X, pushing the propulsion block forward. 201 moves toward the flexible display module 10, thereby causing one side surface of the push block 201 to contact the backlight surface 10F of the flexible display module 10, changing the bending state of the flexible display module 10, and the flexible display module 10 in the second state is bent in the first direction X; the push block 202 pulls the push block 201 back to move away from the flexible display module 10, thereby causing one side surface of the push block 201 to leave the flexible display module 10 and not contact the backlight surface 10F of the flexible display module 10, and the flexible display module 10 returns to a flat state.
[0063] Optional, such as Figure 6 and Figure 7 As shown, the surface of the push block 201 facing the flexible display module 10 can be curved, so that when the push block 201 first comes into contact with the flexible display module 10, the flexible display module 10 can be changed from a planar shape to a curved shape (a slightly curved shape, not shown in the figure); and when the push block 201 is in full contact with the flexible display module 10, the flexible display module 10 is changed to bend into a curved shape consistent with the surface of the push block 201 (the curved shape to the maximum extent).
[0064] Optionally, the propulsion assembly 20 of this embodiment may include two propellers 202, which are respectively disposed on both sides of the propulsion block 201 in the first direction X near the edge. The propeller 202 can be a set of screw 202A and nut 202B. The nut 202B can be fixed to the propulsion block 201. The nut 202B is sleeved on the screw 202A. By rotating the nut 202B on the screw 202A, the nut 202B moves back and forth, thereby driving the propulsion block 201 to move back and forth in a direction closer to or further away from the flexible display module 10. Figure 6 and Figure 7 (The direction of arrow G in the image).
[0065] It is understood that the structure of the thruster 202 in this embodiment is only illustrative. In specific implementations, the structure of the thruster 202 includes, but is not limited to, this. The thrusting component 20 used to change the bending shape of the flexible display module 10 can also be other structures. The rotation of the nut on the screw in this embodiment can be automatically controlled by a structure such as a motor. This embodiment will not elaborate on this, but you can refer to the rotation structure of the nut and screw in related technologies for a better understanding.
[0066] Optional, such as Figure 6 and Figure 7 As shown, along the first direction X, the flexible display module 10 includes a central area 10A and edge areas 10B located on both sides of the central area 10A; in the second state, the flexible display module 10 of the central area 10A is recessed inward toward the direction of the pusher 202.
[0067] In this embodiment, the push block 201 includes a first surface 201A facing the flexible display module 10. The first surface 201A is a concave arc shape. More specifically, the first surface 201A is a concave arc shape that bends in the first direction X. Therefore, when the pushers 202 disposed on both sides of the push block 201 push the push block 201 to move closer to the flexible display module 10, after the first surface 201A contacts the backlight surface 10F of the flexible display module 10, the flexible display module 10 gradually forms a curved shape consistent with the first surface 201A in the second state. That is, along the first direction X, the flexible display module 10 in the middle area 10A is concave inward towards the pusher 202, which helps to ensure the privacy of the display screen when the display device 000 is displayed in the vehicle field.
[0068] Optional, such as Figure 8 and Figure 9 As shown, Figure 8 This is a schematic diagram of another structure of the display device provided in the first state according to an embodiment of the present invention. Figure 9 This is another structural schematic diagram of the display device provided in the second state according to the embodiment of the present invention. Along the first direction X, the flexible display module 10 includes a middle area 10A and edge areas 10B located on both sides of the middle area 10A. In the second state, the flexible display module 10 of the middle area 10A protrudes outward in a direction away from the pusher 202.
[0069] In this embodiment, the push block 201 includes a first surface 201A facing the flexible display module 10. The first surface 201A is a convex arc shape. More specifically, the first surface 201A is a convex arc shape that bends in the first direction X. Therefore, when the pushers 202 disposed on both sides of the push block 201 push the push block 201 to move closer to the flexible display module 10, after the first surface 201A contacts the backlight surface 10F of the flexible display module 10, the flexible display module 10 gradually forms a curved shape consistent with the first surface 201A in the second state. That is, along the first direction X, the flexible display module 10 in the middle area 10A convexes outward in the direction away from the pusher 202. This is suitable for the display device 000 to perform split-screen display in the automotive field, which can simultaneously display different images to the driver and the passenger.
[0070] It should be noted that in this embodiment, the nut 202B of the pusher 202 is fixed to the pusher block 201, and the nut 202B is sleeved on the screw 202A. The rotation of the nut 202B on the screw 202A causes the nut 202B to move back and forth, thereby driving the pusher block 201 to move back and forth towards or away from the flexible display module 10. In the first state, the pusher block 201 is not in contact with the flexible display module 10, that is, the nut 202B carries the pusher block 201 away from the flexible display module 10. Therefore, when the nut 202B is sleeved on the screw 202A, the exposed screw 202B... The length of A is H1; in the second state, when the push block 201 contacts the flexible display module 10, causing the flexible display module 10 to be in a bent state, that is, when the nut 202B brings the push block 201 closer to the flexible display module 10, the exposed length of the screw 202A when the nut 202B is sleeved on the screw 202A is H2, which is greater than H1. That is, when the first state changes to the second state, the nut 202B drives the push block 201 to move closer to the flexible display module 10, and the exposed length H2 of the screw 202A when the nut 202B is sleeved on the screw 202A is longer.
[0071] In some alternative embodiments, please refer to the references. Figure 10 , Figure 11 , Figure 12 and Figure 13 , Figure 10 This is a schematic diagram of another structure of the display device provided in the first state according to an embodiment of the present invention. Figure 11 This is a schematic diagram of another structure of the display device provided in the second state according to an embodiment of the present invention. Figure 12 yes Figure 10 A side view structural diagram. Figure 13 yes Figure 10 and Figure 11A schematic diagram of the structure of the first motor, the first stage gear and the second stage gear in the thruster (the structure of the thruster in this embodiment is filled with transparency). In this embodiment, the thruster 202 includes a first motor 202C (not filled in the figure) and a first stage gear 202D, a first slide bar 202E controlled by the first motor 202C, a first slider 202F sleeved on the first slide bar 202E and a second stage gear 202G.
[0072] The first slide bar 202E extends in a direction perpendicular to the light-emitting surface 10E of the flexible display module 10 (that is, the direction in which the push block 201 moves, indicated by arrow G in the figure). The bottom of the push block 201 is fixed to the top of the first slider 202F. The bottom of the first slider 202F meshes with the second gear 202G. The second gear 202G meshes with the first gear 202D.
[0073] The push block 201 includes a first surface 201A facing the flexible display module 10. The first surface 201A is a concave arc surface or a convex arc surface. In this embodiment, the first surface 201A is a concave arc surface that is curved in the first direction X.
[0074] In the first state, the first motor 202C controls the first stage gear 202D to drive the second stage gear 202G, the second stage gear 202G drives the first slider 202F to slide on the first slide bar 202E, and the first slider 202F drives the push block 201 to move away from the flexible display module 10.
[0075] In the second state, the first motor 202C controls the first stage gear 202D to drive the second stage gear 202G. The second stage gear 202G drives the first slider 202F to slide on the first slide bar 202E. The first slider 202F drives the push block 201 to move towards the flexible display module 10. The first surface 201A contacts the side of the flexible display module 10 away from the light-emitting surface (the backlight surface 10F of the flexible display module 10). The bending state of the flexible display module 10 is consistent with the bending state of the first surface 201A.
[0076] This embodiment explains that the propeller 202 in the propulsion assembly 20 can have a structure including a first motor 202C and a first-stage gear 202D controlled by the first motor 202C, a first slide bar 202E, a first slider 202F sleeved on the first slide bar 202E, and a second-stage gear 202G. The propulsion block 201 can still be controlled by the propeller 202 and include a first surface 201A. When the first motor 202C starts, it controls the first-stage gear 202D to rotate. The first-stage gear 202D meshes with the second-stage gear 202G. After the second-stage gear 202G rotates, it drives the first slider 202F, which meshes with it, to slide on the first slide bar 202E, and this is along a vertical path. The pusher 201 moves in the direction of the light-emitting surface 10E of the flexible display module 10 (i.e., the direction in which the pusher block 201 moves, indicated by arrow G in the figure). The bottom of the first slider 202F is provided with meshing teeth for meshing with the second-stage gear 202G. The top of the first slider 202F is fixed to the bottom of the pusher block 201. When the first slider 202F slides on the first slide bar 202E (the first slide bar 202E can be understood as being in a fixed state, and the first slide bar 202E is only used for the first slider 202F to slide on it), it can drive the pusher block 201 to move closer to or away from the flexible display module 10, thereby realizing the free switching between the first state and the second state of the display device 000. The pusher 202 in this embodiment has a simple structure and a high degree of automation, which is conducive to realizing the flexible switching of the state of the display device 000 and ensuring that the display device 000 can achieve different display effects when in use.
[0077] Optional, such as Figure 14 and Figure 15 As shown, Figure 14 This is a schematic diagram of another structure of the display device provided in the first state according to an embodiment of the present invention. Figure 15 yes Figure 14 The side view of the structure is shown in the figure (it is understood that the figure is filled with transparency in order to clearly illustrate the structure of this embodiment). In this embodiment, the thruster 202 may also include a third-stage gear 202H. The first-stage gear 202D and the second-stage gear 202G mesh through the third-stage gear 202H. That is, the first-stage gear 202D meshes with the third-stage gear 202H, the third-stage gear 202H meshes with the second-stage gear 202G, and the second-stage gear 202G meshes with the bottom of the first slider 202F. The third-stage gear 202H is used to appropriately reduce the rotational speed of the second-stage gear 202G, which is beneficial to improving the service life of the thruster 202.
[0078] In some alternative embodiments, please refer to the references. Figure 16 and Figure 17 , Figure 16 This is a schematic diagram of another structure of the display device provided in the first state according to an embodiment of the present invention. Figure 17 This is another structural schematic diagram of the display device provided in the second state according to the embodiment of the present invention. In this embodiment, when the display device 000 is in the second state, the flexible display module 10 is in a bent state in the first direction X. The figure takes the example of the middle area 10A of the flexible display module 10 being recessed towards the direction of the pusher 202.
[0079] The propulsion assembly 20 includes a power structure 203 and a plurality of independent propulsion structures 204 controlled by the power structure 203, the plurality of propulsion structures 204 being arranged along a first direction X;
[0080] In the first state, the multiple propulsion structural components 204 do not contact the side of the flexible display module 10 away from the light-emitting surface (the backlight surface 10F of the flexible display module 10), and the flexible display module 10 is in a planar state.
[0081] In the second state, the power structure 203 controls multiple propulsion structures 204 to move toward the flexible display module 10. The side of the propulsion structure 204 facing the flexible display module 10 contacts the side of the flexible display module 10 away from the light-emitting surface (the backlight surface 10F of the flexible display module 10), and the flexible display module 10 is in a bent state.
[0082] This embodiment explains the structure of the propulsion assembly 20 used to change the planar state and bending state of the flexible display module 10. It may include a power structure 203 and multiple independent propulsion structures 204 controlled by the power structure 203. The multiple propulsion structures 204 can be disposed on one side of the backlight surface 10F of the flexible display module 10 and uniformly arranged along the first direction X. The multiple propulsion structures 204 are independent of each other. Each propulsion structure 204 can be understood as a block-shaped structure. The power structure 203 is used to control the movement of the propulsion structures 204. Specifically, the power structure 203 can control the multiple propulsion structures 204 to move in directions closer to or further away from the flexible display module 10 (in the direction indicated by arrow G in the figure). In the first state, the power structure 203 controls multiple propulsion structures 204 to move away from the flexible display module 10, so that the multiple propulsion structures 204 do not contact the side of the flexible display module 10 away from the light-emitting surface (the backlight surface 10F of the flexible display module 10), and the flexible display module 10 is in its original planar state. When the display device 000 switches to the second state, the power structure 203 controls multiple propulsion structures 204 to move closer to the flexible display module 10, so that the side of the propulsion structures 204 facing the flexible display module 10 contacts the side of the flexible display module 10 away from the light-emitting surface (the backlight surface 10F of the flexible display module 10). The multiple propulsion structures 204 in the first direction X push at different positions of the flexible display module 10, and the flexible display module 10 is pushed into a bent state. The control of the power structure 203 in the propulsion assembly 20 of this embodiment not only achieves a high degree of automation and effectively realizes flexible switching of the display device 000 state, but also, through the setting of multiple independent propulsion structure 204, can dynamically adjust the bending curvature of different positions of the flexible display module 10 in the second state, making the curvature variability of the display device 000 in the second state more flexible.
[0083] It is understood that this embodiment does not limit the specific structure of the power structure 203. The power structure 203 can be a drive structure that can drive multiple propulsion structures 204 forward or backward. For details, please refer to the description of the following embodiments.
[0084] Optionally, when the display device 000 in this embodiment transitions from the first state to the second state, if the pushing structure 204 in the first state does not contact the backlight surface 10F of the flexible display module 10, but the distance between them is relatively close, then when switching to the second state, only a portion of the pushing structure 204 corresponding to the edge area 10B of the flexible display module 10 in the first direction X can be controlled to move towards the flexible display module 10. When the bending deformation of the edge area 10B of the flexible display module 10 is large enough, the flexible display module 10 in the middle area 10A will inevitably deform in the opposite direction (i.e., deform towards the pushing structure 204). At this time, a portion of the pushing structure 204 corresponding to the middle area 10A of the flexible display module 10 moves away from the flexible display module 10 to provide space for the deformed middle area 10A of the flexible display module 10. It is understood that, in specific implementations, the moving direction and moving method of multiple pushing structure 204 can be set according to the actual situation. In subsequent embodiments, if necessary, the movement mode of the multiple propulsion structure components 204 may also refer to this embodiment, and will not be elaborated in subsequent embodiments.
[0085] In this embodiment, multiple propulsion structural members 204 are arranged sequentially along the first direction X on one side of the backlight surface 10F of the flexible display module 10. The propulsion structural members 204 can be... Figure 16 and Figure 17 The block structure in the middle. Optionally, the pushing structure 204 includes a first end 204A facing the flexible display module 10. The first end 204A is arc-shaped, so that when different pushing structures 204 move in the direction closer to the flexible display module 10, even if the degree and force of pushing different pushing structures 204 toward the flexible display module 10 are different, the contact area between different pushing structures 204 and the backlight surface 10F of the flexible display module 10 is the same in the second state, which is beneficial to ensure the uniformity of the bending of the flexible display module 10 in the second state.
[0086] Optional, such as Figure 18 As shown, Figure 18 This is another structural schematic diagram of the display device provided in the first state according to the embodiment of the present invention. In this embodiment, the push structure 204 includes a first end 204A facing the flexible display module 10. The first end 204A includes a protective layer 204A1. The material of the protective layer 204A1 includes either silicone or foam.
[0087] This embodiment explains that the first end 204A of the propulsion structure 204 of the propulsion assembly 20 includes a protective layer 204A1. When the display device 000 is in the second state and the propulsion structure 204 is in contact with the backlight surface 10F of the flexible display module 10, the material of the protective layer 204A1, such as silicone or foam, can protect the flexible display module 10, avoid damage to the flexible display module 10 caused by the thrust of the propulsion structure 204, and help to improve the service life of the display device 000.
[0088] It should be noted that the figure in this embodiment is only a block diagram to illustrate the power structure 203. Its specific structure and the specific connection relationship with the propulsion structure 204 can be understood by referring to the description of the following embodiments. This embodiment is not limited here, as long as the power structure 203 can control multiple independent propulsion structures 204 to move towards or away from the flexible display module 10.
[0089] In some alternative embodiments, please refer to the references. Figure 19 , Figure 20 and Figure 21 , Figure 19 This is a schematic diagram of another structure of the display device provided in the first state according to an embodiment of the present invention. Figure 20 This is a schematic diagram of another structure of the display device provided in the second state according to an embodiment of the present invention. Figure 21 yes Figure 19 A side view of the structure (to clearly illustrate the structure of this embodiment). Figure 19 and Figure 20 (Transparency fill has been applied in the middle). In this embodiment, the power structure 203 includes a second motor 2031 and a plurality of first gear assemblies 2032, and a first gear assembly 2032 is correspondingly connected to a propulsion structure 204.
[0090] Each first gear assembly 2032 includes a first gear 2032A, a second slide bar 2032B, and a second slider 2032C and a second gear 2032D sleeved on the second slide bar 2032B;
[0091] The second slide bar 2032B extends in a direction perpendicular to the light-emitting surface 10E of the flexible display module 10 (that is, the direction in which the push structure 204 moves, indicated by arrow G in the figure). The bottom of the push structure 204 is fixed to the top of the second slider 2032C. The bottom of the second slider 2032C meshes with the second gear 2032D. The second gear 2032D meshes with the first gear 2032A.
[0092] In the first state, the second motor 2031 controls the first gear 2032A to drive the second gear 2032D. The second gear 2032D drives the second slider 2032C to slide on the second slide bar 2032B. The second slider 2032C drives the push structure 204 to move away from the flexible display module 10. The push structure 204 does not contact the side of the flexible display module 10 away from the light-emitting surface (the backlight surface 10F of the flexible display module 10).
[0093] In the second state, the second motor 2031 controls the first gear 2032A to drive the second gear 2032D. The second gear 2032D drives the second slider 2032C to slide on the second slide bar 2032B. The second slider 2032C drives the push structure 204 to move towards the side closer to the flexible display module 10. The side of the push structure 204 facing the flexible display module 10 contacts the side of the flexible display module away from the light-emitting surface (the backlight surface 10F of the flexible display module 10).
[0094] During the transition from the first state to the second state, at least two propulsion structural members 204 move different distances in the direction perpendicular to the light-emitting surface 10E of the flexible display module 10.
[0095] This embodiment explains that the propulsion assembly 20 includes a power structure 203 and multiple independent propulsion structures 204 controlled by the power structure 203. When the multiple propulsion structures 204 are disposed on one side of the backlight surface 10F of the flexible display module 10 and are uniformly arranged along the first direction X, the power structure 203 may include a general second motor 2031 and multiple first gear assemblies 2032. The second motor 2031 may be a high-power motor to drive different multiple first gear assemblies 2032. The number of multiple first gear assemblies 2032 may be the same as the number of multiple propulsion structures 204. One first gear assembly 2032 is correspondingly connected to one propulsion structure 204. That is, under the control of the high-power second motor 2031, one first gear assembly 2032 drives one propulsion structure 204 to move in a direction closer to or away from the flexible display module 10.
[0096] Each first gear assembly 2032 includes a first gear 2032A, a second slide bar 2032B, and a second slider 2032C and a second gear 2032D sleeved on the second slide bar 2032B. Each propulsion structure 204 can be controlled by one first gear assembly 2032. The shape and structure of the propulsion structure 204 can be as shown in the above embodiment, and will not be described in detail here.
[0097] When the high-power second motor 2031 of this embodiment starts, multiple first gear assemblies 2032 are driven together to control the rotation of the first gear 2032A. The first gear 2032A meshes with the second gear 2032D. After the second gear 2032D rotates, it drives the second slider 2032C, which meshes with it, to slide on the second slide bar 2032B. The slider 2032C moves in a direction perpendicular to the light-emitting surface 10E of the flexible display module 10 (that is, the direction in which the push structure 204 moves, indicated by arrow G in the figure). The bottom of the second slider 2032C is provided with meshing teeth for meshing with the second gear 2032D. The top of the second slider 2032C is fixed to the bottom of the push structure 204. When the second slider 2032C slides on the second slide bar 2032B, it can drive the push structure 204 to move towards or away from the flexible display module 10, thereby realizing the free switching between the first state and the second state of the display device 000. In this embodiment, the propulsion assembly 20 employs a high-power second motor 2031 to drive multiple different first gear assemblies 2032. This allows different propulsion structural members 204 to move at different distances in the direction perpendicular to the light-emitting surface 10E of the flexible display module 10. Specifically, during the transition from the first state to the second state, at least two propulsion structural members 204 controlled by different first gear assemblies 2032 move at different distances in the direction perpendicular to the light-emitting surface 10E of the flexible display module 10. This results in different displacements of the propulsion structural members 204, leading to different pushing distances of the propulsion structural members 204 onto the flexible display module 10. Consequently, the bending shape of the flexible display module 10 in the second state can be freely adjusted. In this embodiment, the propulsion assembly 20 uses only a high-power second motor 2031 to control the travel distance of different propulsion structural members 204. This simple structure and high degree of automation facilitate flexible switching of the display device 000's states, ensuring that the display device 000 achieves different display effects during use.
[0098] Optionally, since the different propulsion structures 204 in this embodiment travel different distances under the control of different first gear assemblies 2032, and the different first gear assemblies 2032 are controlled by the same second motor 2031, the number and size of the teeth of the first gear 2032A corresponding to the different propulsion structures 204 in the first gear assembly 2032 are different, and the number and size of the teeth of the second gear 2032D corresponding to the different propulsion structures 204 are different (not shown in the figure, only represented by the same filling pattern). That is, when the second motor 2031 rotates the same number of revolutions, the number of teeth meshed by the first gear 2032A and the second gear 2032D in the different first gear assemblies 2032 are different. Therefore, the second slider 2032C of the different first gear assemblies 2032 can be controlled to slide different distances on the second slide rod 2032B, thereby realizing that the different propulsion structures 204 move different distances along the direction perpendicular to the light-emitting surface 10E of the flexible display module 10. In this embodiment, by setting different numbers and sizes of teeth on the first gear 2032A corresponding to different propulsion structure components 204, and different numbers and sizes of teeth on the second gear 2032D corresponding to different propulsion structure components 204, when the same second motor 2031 controls different first gear assemblies 2032, although the number of rotations is the same, the travel distance of different propulsion structure components 204 can be different, thereby allowing the bending shape of the flexible display module 10 in the second state to be freely adjusted.
[0099] It is understood that the number of propulsion structural members 204 and the number of first gear assemblies 2032 included in the propulsion component 20 in the figure of this embodiment are only illustrative examples. In specific implementation, the number and arrangement interval between adjacent propulsion structural members 204 can be specifically set according to the size of the display device 000 in the first direction X and the bending requirements of the display device 000 in the second state. This embodiment does not limit this.
[0100] Optional, such as Figures 19-21 As shown, in this embodiment, in the first direction X, along the edge 10L of the flexible display module 10 pointing towards the middle region of the flexible display module 10, a plurality of propulsion structures 204 include a first propulsion structure 204 (1), a second propulsion structure 204 (2), ..., the i-th propulsion structure 204 (i); during the transition from the first state to the second state, the second motor 2031 controls the first propulsion structure 204 (1) to move a distance S1 closer to the flexible display module 10, the second motor 2031 controls the second propulsion structure 204 (2) to move a distance S2 closer to the flexible display module 10, ..., the second motor 2031 controls the i-th propulsion structure 204 (i) to move a distance Si closer to the flexible display module 10, S1 > S2 > ... > Si, i is an integer greater than 2 ( Figure 20The dashed line P1 indicates the position of each propulsion structure 204 in the first state. This allows the propulsion structure 204 to move a smaller distance towards the flexible display module 10 during the transition from the first state to the second state as it approaches the middle area of the flexible display module 10, and a larger distance as it approaches the edge 10L of the flexible display module 10. This enables the flexible display module 10 to achieve a concave bending state in the middle area towards the propulsion assembly 20 in the second state, which helps to ensure the privacy of the display screen of the display device 000.
[0101] Optional, such as Figure 19 and Figure 22 As shown, Figure 22 This is a schematic diagram of another structure of the display device provided in the second state according to an embodiment of the present invention (for the purpose of clearly illustrating the structure of this embodiment, Figure 22 (Transparency filling was performed in the middle), in this embodiment, in the first direction X, along the edge 10L of the flexible display module 10 pointing to the middle area of the flexible display module 10, the multiple propulsion structures 204 include the first propulsion structure 204 (1), the second propulsion structure 204 (2), ..., the i-th propulsion structure 204 (i); during the process of the first state changing to the second state, the second motor 2031 controls the first propulsion structure 204 (1) to move closer to the flexible display module 10 by a distance S11, the second motor 2031 controls the second propulsion structure 204 (2) to move closer to the flexible display module 10 by a distance S21, ..., the second motor 2031 controls the i-th propulsion structure 204 (i) to move closer to the flexible display module 10 by a distance Si1, S11 < S21 < ... < Si1, i is an integer greater than 2 ( Figure 22 The dotted line P2 indicates the position of each propulsion structure 204 in the first state. This allows the propulsion structure 204 to move a greater distance towards the flexible display module 10 during the transition from the first state to the second state as it approaches the center area of the flexible display module 10. Conversely, the propulsion structure 204 moves a smaller distance towards the flexible display module 10 during the transition from the first state to the second state as it approaches the edge 10L of the flexible display module 10. This enables the flexible display module 10 in the second state to achieve an outwardly convex bending state that moves away from the propulsion assembly 20. This is suitable for display devices 000 to perform split-screen displays in the automotive field, allowing different images to be displayed to the driver and passenger simultaneously.
[0102] In some alternative embodiments, please refer to the references. Figure 23 and Figure 24 , Figure 23 This is a schematic diagram of another structure of the display device provided in the first state according to an embodiment of the present invention. Figure 24 This is a schematic diagram of another structure of the display device provided in the second state according to an embodiment of the present invention (for the purpose of clearly illustrating the structure of this embodiment, Figure 23 and Figure 24 (Transparency fill has been applied in the middle). In this embodiment, the power structure 203 includes multiple third motors 2033 and multiple second gear assemblies 2034. One third motor 2033 and one second gear assembly 2034 are correspondingly connected to one propulsion structure 204.
[0103] Each second gear assembly 2034 includes a third gear 2034A, a third slide bar 2034B, a third slider 2034C sleeved on the third slide bar 2034B, and a fourth gear 2034D.
[0104] The third slide bar 2034B extends in a direction perpendicular to the light-emitting surface 10E of the flexible display module 10 (that is, the direction in which the push structure 204 moves, indicated by arrow G in the figure). The bottom of the push structure 204 is fixed to the top of the third slider 2034C. The bottom of the third slider 2034C meshes with the fourth gear 2034D. The fourth gear 2034D meshes with the third gear 2034A.
[0105] In the first state, in the third motor 2033 corresponding to each propulsion structure 204, the third motor 2033 controls the third gear 2034A to drive the fourth gear 2034D, the fourth gear 2034D drives the third slider 2034C to slide on the third slider 2034B, and the third slider 2034C drives the propulsion structure 204 to move away from the flexible display module 10. The propulsion structure 204 does not contact the side of the flexible display module 10 away from the light-emitting surface 10E (that is, the backlight surface 10F of the flexible display module 10).
[0106] In the second state, in the third motor 2033 corresponding to each propulsion structure 204, the third motor 2033 controls the third gear 2034A to drive the fourth gear 2034D, the fourth gear 2034D drives the third slider 2034C to slide on the third slider 2034B, and the third slider 2034C drives the propulsion structure 204 to move towards the flexible display module 10. The side of the propulsion structure 204 facing the flexible display module 10 contacts the side of the flexible display module 10 away from the light-emitting surface 10E (that is, the backlight surface 10F of the flexible display module 10).
[0107] During the transition from the first state to the second state, at least two propulsion structural members 204 move different distances in the direction perpendicular to the light-emitting surface 10E of the flexible display module 10.
[0108] This embodiment explains that the propulsion assembly 20 includes a power structure 203 and multiple independent propulsion structures 204 controlled by the power structure 203. When the multiple propulsion structures 204 are disposed on one side of the backlight surface 10F of the flexible display module 10 and are uniformly arranged along the first direction X, the power structure 203 may include multiple third motors 2033 and multiple second gear assemblies 2034. The number of third motors 2033, the number of second gear assemblies 2034, and the number of propulsion structures 204 can be the same. One third motor 2033 and one second gear assembly 2034 are correspondingly connected to one propulsion structure 204, so that the independent propulsion structures 204 can be separately controlled by their respective third motors 2033 and second gear assemblies 2034. Among the third motors 2033 and second gear assemblies 2034 corresponding to each propulsion structure 204, one second gear assembly 2034 drives one propulsion structure 204 to move towards or away from the flexible display module 10 under the control of its corresponding third motor 2033.
[0109] Each second gear assembly 2034 includes a third gear 2034A, a third slide bar 2034B, a third slider 2034C sleeved on the third slide bar 2034B, and a fourth gear 2034D. Each propulsion structure 204 can be controlled by one second gear assembly 2034. The shape and structure of the propulsion structure 204 can be as shown in the above embodiment, and will not be described in detail here.
[0110] When each of the third motors 2033 in this embodiment is started, the second gear assembly 2034 connected to it is driven, controlling the third gear 2034A to rotate. The third gear 2034A meshes with the fourth gear 2034D. After the fourth gear 2034D rotates, it drives the third slider 2034C, which meshes with it, to slide on the third slide bar 2034B. The slider moves in a direction perpendicular to the light-emitting surface 10E of the flexible display module 10 (that is, the direction in which the push structure 204 moves, indicated by arrow G in the figure). The bottom of the third slider 2034C is provided with meshing teeth for meshing with the fourth gear 2034D. The top of the third slider 2034C is fixed to the bottom of the push structure 204. When the third slider 2034C slides on the third slide bar 2034B, it can drive the push structure 204 to move towards or away from the flexible display module 10, thereby realizing the free switching between the first state and the second state of the display device 000. In this embodiment, the propulsion assembly 20 employs multiple third motors 2033 to independently drive multiple different second gear assemblies 2034, thereby achieving different displacements of different propulsion structural members 204 in the direction perpendicular to the light-emitting surface 10E of the flexible display module 10. That is, during the transition of the display device from the first state to the second state, at least two propulsion structural members 204 controlled by different second gear assemblies 2034 move different distances in the direction perpendicular to the light-emitting surface 10E of the flexible display module 10. As a result, the propulsion structural members 204 can travel different displacements, causing the propulsion structural members 204 to push the flexible display module 10 at different distances. This allows for free adjustment of the bending shape of the flexible display module 10 in the second state.
[0111] In this embodiment, the propulsion component 20 employs multiple independent third motors 2033 to control the travel distance of different propulsion structural components 204. The third motors 2033 can be low-power motors, which are small in size and low in noise, have high control flexibility and high degree of automation, which is conducive to the flexible switching of the display device 000 state and ensures that the display device 000 achieves different display effects when in use.
[0112] Optionally, the second gear assemblies 2034 corresponding to the different propulsion structures 204 in this embodiment have the same structure. Since the different propulsion structures 204 in this embodiment travel different distances under the control of different second gear assemblies 2034, and the different second gear assemblies 2034 are controlled by different third motors 2033, the number and size of the teeth of the third gear 2034A corresponding to the different propulsion structures 204 in the second gear assembly 2034 are the same, and the number and size of the teeth of the fourth gear 2034D corresponding to the different propulsion structures 204 are the same (not shown in the figure, only represented by the same filling pattern). That is, the independent third motor 2033 can control the gears of the different second gear assemblies 2034 to rotate different numbers of revolutions, so that the third slider 2034C of the different second gear assemblies 2034 slides on the third slide bar 2034B at different distances, thereby realizing that the different propulsion structures 204 move at different distances in the direction perpendicular to the light-emitting surface 10E of the flexible display module 10. Furthermore, when the structures of the second gear assemblies 2034 corresponding to different propulsion structural components 204 are the same, multiple second gear assemblies 2034 can be manufactured using the same set of molds, which is beneficial to improving the process efficiency of the entire display device and saving manufacturing costs.
[0113] In this embodiment, by setting the number and size of the teeth of the third gear 2034A corresponding to different propulsion structure components 204 to be the same, and the number and size of the teeth of the fourth gear 2034D corresponding to different propulsion structure components 204 to be the same, and by using different third motors 2033 to control different second gear assemblies 2034, the number of rotations of the gears in the different second gear assemblies 2034 are different, so as to achieve different travel distances of different propulsion structure components 204, thereby allowing the bending shape of the flexible display module 10 in the second state to be freely adjusted.
[0114] It is understood that the number of propulsion structural members 204 and the number of second gear assemblies 2034 included in the propulsion component 20 in the figure of this embodiment are only illustrative examples. In specific implementation, the number and arrangement interval between adjacent propulsion structural members 204 can be specifically set according to the size of the display device 000 in the first direction X and the bending requirements of the display device 000 in the second state. This embodiment does not limit this.
[0115] Optional, such as Figure 23 and Figure 24As shown, in this embodiment, in the first direction X, along the edge 10L of the flexible display module 10 pointing to the middle region of the flexible display module 10, a plurality of propulsion structures 204 include a first propulsion structure 204(1), a second propulsion structure 204(2), ..., the j-th propulsion structure 204(j); a plurality of third motors 2033 include a first third motor 2033(1), a second third motor 2033(2), ..., the j-th third motor 2033(j); the first state is converted to the second state. During the process, the first third motor 2033(1) controls the first propulsion structure 204(1) to move a distance L1 closer to the flexible display module 10, the second third motor 2033(2) controls the second propulsion structure 204(2) to move a distance L2 closer to the flexible display module 10, ..., the j-th third motor 2033(j) controls the j-th propulsion structure 204(j) to move a distance Lj closer to the flexible display module, L1 > L2 > ... > Lj, where j is an integer greater than 2 ( Figure 24 The dotted line P3 indicates the position of each propulsion structure 204 in the first state. This allows the propulsion structure 204 to move a smaller distance towards the flexible display module 10 during the transition from the first state to the second state as it approaches the middle area of the flexible display module 10, and a larger distance as it approaches the edge 10L of the flexible display module 10. This enables the flexible display module 10 to achieve a concave bending state in the middle area towards the propulsion assembly 20 in the second state, which helps to ensure the privacy of the display screen of the display device 000.
[0116] Optional, such as Figure 23 and Figure 25 As shown, Figure 25 This is a schematic diagram of another structure of the display device provided in the second state according to an embodiment of the present invention (for the purpose of clearly illustrating the structure of this embodiment, Figure 25(Transparency filling was performed in the middle). In this embodiment, in the first direction X, along the edge 10L of the flexible display module 10 pointing to the middle area of the flexible display module 10, a plurality of propulsion structures 204 include a first propulsion structure 204 (1), a second propulsion structure 204 (2), ..., the j-th propulsion structure 204 (j); a plurality of third motors 2033 include a first third motor 2033 (1), a second third motor 2033 (2), ..., the j-th third motor 2033 (j); the first state is converted to the second state. During the process, the first third motor 2033(1) controls the first propulsion structure 204(1) to move a distance L11 closer to the flexible display module 10, the second third motor 2033(2) controls the second propulsion structure 204(2) to move a distance L21 closer to the flexible display module 10, ..., the j-th third motor 2033(j) controls the j-th propulsion structure 204(j) to move a distance Lj1 closer to the flexible display module, L11 < L21 < ... < Lj1, where j is an integer greater than 2 ( Figure 25 The dotted line P4 indicates the position of each propulsion structure 204 in the first state. This allows the propulsion structure 204 to move a smaller distance towards the flexible display module 10 during the transition from the first state to the second state as it approaches the center area of the flexible display module 10. Conversely, the propulsion structure 204 moves a larger distance towards the flexible display module 10 during the transition from the first state to the second state as it approaches the edge 10L of the flexible display module 10. This enables the flexible display module 10 to achieve an outward convex bending state in the second state, moving away from the propulsion assembly 20. This is suitable for display devices 000 to perform split-screen displays in the automotive field, allowing different images to be displayed to the driver and passenger simultaneously.
[0117] In some alternative embodiments, please refer to the references. Figure 26 and Figure 27 , Figure 26 This is a schematic diagram of a display device in a third state according to an embodiment of the present invention. Figure 27 This is a schematic diagram of a display device in a fourth state provided in an embodiment of the present invention. Figure 26 and Figure 27 It can be understood as Figure 1 and Figure 2 (Side view of the display device). In this embodiment, the display device 000 also includes a housing cavity 30 and a lifting mechanism 40 located in the housing cavity 30.
[0118] The display device 000 also includes a third state and a fourth state;
[0119] In the third state, the lifting mechanism 40 controls at least a portion of the light-emitting surface 10E of the flexible display module 10 to be located within the storage cavity 30;
[0120] In the fourth state, the lifting mechanism 40 controls all light-emitting surfaces 10E of the flexible display module 10 to be located outside the storage cavity 30.
[0121] Optionally, in the second state, the flexible display module 10 of the display device 000 in this embodiment is in the first direction X (see reference). Figure 1 and Figure 2 , Figure 26 and Figure 27 The first direction (which can be understood as the direction perpendicular to the plane of the paper where the drawing is located) is curved; the lifting mechanism 40 controls the flexible display module 10 to be curved along the second direction Y ( Figure 26 and Figure 27 The second direction Y can be understood as the up and down direction in the figure; wherein, in the plane where the flexible display module 10 is located in the first state, the first direction X intersects with the second direction Y.
[0122] This embodiment explains that the display device 000 may also include a cavity for housing part of the display device structure. Specifically, the display device 000 also includes a housing cavity 30 and a lifting mechanism 40 located in the housing cavity 30. The lifting mechanism 40 is used to control at least the rise or fall of the flexible display module 10. The housing cavity 30 is used to accommodate the propulsion component 20, part of the flexible display module 10 and the lifting mechanism. The display device 000 also includes a third state and a fourth state. In the third state, which can be understood as the unused state of the display device 000, i.e., the standby storage state, the lifting mechanism 40 controls at least a portion of the light-emitting surface 10E of the flexible display module 10 to be located inside the storage cavity 30. That is, only a portion of the light-emitting surface 10E of the flexible display module 10 is exposed inside the storage cavity 30, or all of the flexible display modules 10 are located inside the storage cavity 30. Thus, before the display device 000 is used, it plays a role in protecting the display device 000. It can also reduce the space occupied by the display device 000 in the central control area when the display device 000 is applied in the automotive field, effectively avoid affecting the vision of the people in the vehicle, and improve the reliability of use. In the fourth state, which can be understood as the usage state of the display device 000, the lifting mechanism 40 controls all the light-emitting surfaces 10E of the flexible display module 10 to rise out from the storage cavity 30 along the second direction Y. That is, the lifting mechanism 40 controls all the light-emitting surfaces 10E of the flexible display module 10 to be located outside the storage cavity 30 for the user to view. After the display device 000 is in the fourth state, the pushing component 20 can control the display device 000 to be in the flat first state or the curved second state to meet the viewing effect of different scenarios.
[0123] It is understood that the figures in this embodiment are merely block diagrams illustrating the lifting mechanism 40. In actual implementation, the specific structure of the lifting mechanism 40 can be understood by referring to structures with lifting functions in related technologies. This embodiment does not limit this aspect. Figure 26 and Figure 27 As shown, the lifting mechanism 40 may include a drive motor 401, a lifting gear 402, a lifting block 403, and a lifting rod 404. The drive motor 401 drives the lifting gear 402 to rotate, and the lifting gear 402 drives the lifting block 403 to rise or fall along the second direction Y on the lifting rod 404, thereby achieving the lifting effect of the lifting mechanism 40. Alternatively, in some other optional embodiments, other structures may be included, as long as the lifting mechanism 40 can control the flexible display module 10 and the propulsion component 20 to rise or fall in the second direction Y.
[0124] In some alternative embodiments, please refer to the references. Figure 28 and Figure 29 , Figure 28 This is a schematic diagram of the main usage mode of the display device in the second state provided in an embodiment of the present invention. Figure 29 This is a schematic diagram of a secondary use mode of the display device in the second state provided in an embodiment of the present invention. Figure 28 and Figure 29 It can be understood as Figure 2 (Side view of the display device). In this embodiment, the display device 000 further includes an angle rotation mechanism 50; the second state includes a main usage mode and an auxiliary usage mode;
[0125] In the main usage mode, the angle rotation mechanism 50 controls the angle between the light-emitting surface 10E of the flexible display module 10 and the horizontal plane PX to be α1;
[0126] In auxiliary use mode, the angle rotation mechanism 50 controls the angle between the light-emitting surface 10E of the flexible display module 10 and the horizontal plane PX to be α2; α1 < α2.
[0127] This embodiment explains that the display device 000 may also include an angle rotation mechanism 50. The angle rotation mechanism 50 can be installed on the side of the propulsion component 20 away from the flexible display module 10, or when the display device 000 includes a receiving cavity, the angle rotation mechanism 50 can be installed below the receiving cavity. The angle rotation mechanism 50 can be a structure that enables the angle rotation function of the display device 000 or enables the display device 000 to swing, so that the light-emitting surface 10E of the flexible display module 10 can be rotated to a certain angle. When the display device 000 is applied in the automotive field, the angle of the light-emitting surface 10E of the flexible display module 10 can be controlled to facilitate viewing by drivers and other users. Specifically, in the second state, after the flexible display module 10 is bent, the display device 000 can include a main use mode and an auxiliary use mode. In the main use mode, the angle rotation mechanism 50 controls the light-emitting surface 10E of the flexible display module 10 to be aligned with the horizontal plane PX (it can be understood that the horizontal plane in this embodiment can be understood as the ground surface plane of the display device 000 in the installation environment, or it can be understood as...). Figure 28 and Figure 29 In the horizontal direction (as shown in the diagram), the angle is a smaller α1. In the auxiliary use mode, the angle rotation mechanism 50 controls the angle between the light-emitting surface 10E of the flexible display module 10 and the horizontal plane PX to be a larger α2, where α2 can be a right angle and α1 can be an acute angle. The angle rotation mechanism 50 in this embodiment can control the tilt angle of the light-emitting surface 10E of the flexible display module 10 in the second display state of the display device 000. When the display device 000 of this embodiment is applied to vehicle display, the angle rotation mechanism 50 can be used to change the orientation of the light-emitting surface 10E of the flexible display module 10 towards users of different heights, so as to suit users such as drivers or passengers of different heights, thereby improving the versatility, flexibility and satisfaction of user use.
[0128] It is understood that this embodiment is only an example illustrating that the different elevation angles of the light-emitting surface 10E of the flexible display module 10 in the second state can be achieved through the angle rotation mechanism 50. In specific implementation, other methods can also be used, such as using a mechanical gear assembly in conjunction with a motor drive to adjust the different tilt angles of the light-emitting surface 10E of the flexible display module 10, and using a limiter to control the maximum tilt angle; or the tilt degree of the light-emitting surface 10E of the flexible display module 10 can be manually adjusted, or other control structures and control methods can be used. This embodiment does not specifically limit these methods, as long as the display device 000 can achieve different elevation angles according to the user's viewing habits.
[0129] As can be seen from the above embodiments, the display device provided by the present invention achieves at least the following beneficial effects:
[0130] The display device provided by this invention includes a flexible display module and a propulsion component. The propulsion component, used to change the planar state and curved state of the flexible display module, is disposed on the non-light-emitting side of the flexible display module. The display device includes at least a first state and a second state, both of which can be understood as the usage states of the display device. In the first state, the propulsion component does not contact the side of the flexible display module away from the light-emitting surface. At this time, the flexible display module maintains its original planar state, making the display device present a flat, straight display. When it is necessary to switch to the second state, the propulsion component can be advanced towards the flexible display module. Eventually, the propulsion component gradually contacts the side of the flexible display module away from the light-emitting surface. After the propulsion component contacts the flexible display module on the non-light-emitting side, it can change the shape of the flexible display module, making the flexible display module curved, and the display device presents a curved surface display. Furthermore, as the propulsion component moves closer to the flexible display module, the degree of shape change in the flexible display module can be controlled by the specific distance the propulsion component travels. For example, the closer the propulsion component is to the flexible display module, the greater the degree of bending of the flexible display module. This allows for both shape adjustment of the flexible display module and dynamic adjustment of its curvature in the second state, making the curvature (degree of bending) of the display device in the second state flexible and variable. When the display device of this invention is applied to in-vehicle displays, it is not only suitable for large-size, large-screen in-vehicle displays, which helps to bring a better riding experience to passengers in the vehicle, but it can also present different forms according to different application scenarios to ensure display effects. By determining the current application scenario of the in-vehicle display, the form of the display device is dynamically adjusted to ensure that the in-vehicle display device presents the best display effect, which helps to improve the user satisfaction of passengers in the vehicle.
