[0029] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one of ordinary skill in the art that the present application can be practiced without some of these specific details. The description of the embodiments is merely to provide a better understanding of the present application by showing examples of the present application.

[0030] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The embodiments will be described in detail below with reference to the accompanying drawings.

[0031] Relative terms such as first and second are used to differentiate one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0032] It will be understood that when a layer, region or element is referred to as being "on" or "above" another layer, region or element, it can be directly on or above the other layer, region or element or intervening layers or regions can also be present. In addition, it will be understood that when a layer, region or element is referred to as being "under" or "below" another layer, region or element, it can be directly under or below the other layer, region or element or intervening layers or regions can also be present. Also, a layer, region, or element can be "on", "above", "under", or "below" another layer, region, or element without directly contacting it.

[0033] In addition, the term "and / or" used herein only means an association between associated objects, and can mean three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0034] It should be understood that in the embodiments of the present application, "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that the determination of B according to A does not mean that B is determined only according to A, but B can also be determined according to A and / or other information.

[0035] The applicant finds that the folding display device usually connects two display modules together through a hinge structure, and enables the two to rotate relative to each other. The hinge structure is elliptical through a gear set, and the connecting part needs to extend to the backlight side of the display module. In order to meet the requirement of structural strength, the connecting part of the hinge structure needs to extend to a larger area of the backlight side of the display module, and has a thickness large enough. Therefore, under the premise that the thickness of the folding display device is determined, the thickness presented after the display module is connected with the hinge structure is large, which occupies the space in the folding display device and affects the endurance of the battery. In addition, if the thickness of the hinge structure is reduced, the cost of the display device will be increased, and the risk of damage will be increased.

[0036] In view of the above analysis, the applicant proposes a display device comprising a first display module, a second display module, a support structure, a first telescopic part and a second telescopic part. The first display module and the second display module are respectively connected with the first connecting area and the second connecting area of the support structure, so that the display device of the present application can have a folding display function. The first telescopic part and the second telescopic part are both arranged at one end of the support structure along the second direction; the first end of the first telescopic part is connected with the support structure, and the connection is located in the first connecting area; the second end is connected with the support structure, and the connection is located in the bending area; the second telescopic part comprises a third end and a fourth end, the third end is connected with the support structure, and the connection is located in the second connecting area; the fourth end is connected with the support structure, and the connection is located in the bending area. By the telescoping of the first telescopic part and the second telescopic part, the display device of the present application can be switched between the folded state and the unfolded state. Since the first telescopic part and the second telescopic part are located at the end of the display device along the second direction, the first display module, the second display module and the support structure form a structure with a smaller thickness, reducing the weight and cost of the display device, and under the premise of determining the thickness of the display device, the battery's endurance can be increased.

Figure 3 A side view of the display device of the present application embodiment along the second direction in the first folded state. Figure 4 A side view of the display device of the present application embodiment along the second direction in the second folded state.

[0038] Please refer to Figures 1 to 4 The present application embodiment provides a display device, comprising: a first display module 1; a second display module 2, one end of the first display module 1 and one end of the second display module 2 are arranged side by side along a first direction X; a support structure 3 comprising a first connecting area 31, a bending area 32 and a second connecting area 33 arranged in sequence along the first direction X, the first display module 1 is at least partially located in the first connecting area 31, and the second display module 2 is at least partially located in the second connecting area 33; a first telescopic part 4 arranged at one end of the support structure 3 along a second direction Y, the first telescopic part 4 comprising a first end 41 and a second end 42, the first end 41 being connected with the support structure 3, and the connection being located in the first connecting area 31, the second end 42 being connected with the support structure 3, and the connection being located in the bending area 32; the first direction X and the second direction Y are perpendicular; a second telescopic part 5 arranged at one end of the support structure 3 along the second direction Y, the second telescopic part 5 comprising a third end 51 and a fourth end 52, the third end 51 being connected with the support structure 3, and the connection being located in the second connecting area 33, the fourth end 52 being connected with the support structure 3, and the connection being located in the bending area 32.

[0039] The display device of the embodiment of the present application is a display device with folding function. When the display device of the embodiment of the present application is unfolded and placed on a horizontal plane, the first direction X and the second direction Y can be two horizontal directions perpendicular to each other. Considering that the display device of the embodiment of the present application can be folded, for the convenience of description, the display device in the unfolded state is taken as an example for description without special description.

[0040] The first display module 1 and the second display module 2 both have display function, and are arranged side by side along the first direction X, that is, the first display module 1 and the second display module 2 are coplanar, and each has an edge close to each other. Exemplarily, the first display module 1 and the second display module 2 can be organic light emitting (OLED) display module, liquid crystal (LCD) display module or micro light emitting diode (Micro-LED) display module.

[0041] The support structure 3 includes a first connecting area 31, a folding area 32 and a second connecting area 33 arranged in sequence along the first direction X. A part of the first display module 1 is located in the first connecting area 31, and the support structure 3 located in a part of the first connecting area 31 can be connected with the backlight side of the first display module 1 in a stacked manner or embedded in the film layer structure of the first display module 1. Similarly, a part of the second display module 2 is located in the second connecting area 33, and the support structure 3 located in a part of the second connecting area 33 can be connected with the backlight side of the second display module in a stacked manner or embedded in the film layer structure of the second display module 2. Therefore, along the first direction X, the folding area 32 of the support structure 3 is located between the first display module 1 and the second display module 2, and the folding function of the display device of the embodiment of the present application can be realized by bending the folding area 32 of the support structure 3.

[0042] The first telescopic part 4 and the second telescopic part 5 are used to fix the relative bending angle of the first display module 1 and the second display module 2. Both of them are arranged at one end of the support structure 3 along the second direction Y. It can be understood that the first telescopic part 4 and the second telescopic part 5 can be arranged at least two, respectively arranged at both ends of the support structure 3 along the second direction Y. The first end 41 of the first telescopic part 4 is connected with the support structure 3, and the connection is located in the first connecting area 31, and the second end 42 is connected with the support structure 3, and the connection is located in the folding area 32; the third end 51 of the second telescopic part 5 is connected with the support structure 3, and the connection is located in the second connecting area 33, and the fourth end 52 is connected with the support structure 3, and the connection is located in the folding area 32. The second end 42 and the fourth end 52 can be directly connected together or not directly connected. Exemplarily, the first telescopic part 4 and the second telescopic part 5 can adopt the form of micro electromagnetic hydraulic rod.

[0043] When the display device of the embodiment of the present application is folded and bent, the bending area 32 of the support structure 3 will be bent and deformed, thus the distance between the connection of the second end 42 and the support structure 3 and the connection of the first end 41 and the support structure 3 is shortened, at this time, the first telescopic part 4 is shortened. Similarly, the distance between the connection of the fourth end 52 and the support structure 3 and the connection of the third end 51 and the support structure 3 is shortened, at this time, the second telescopic part 5 is shortened. By fixing the length of the first telescopic part 4 and the length of the second telescopic part 5, the display device of the present application can be in a certain angle of bending state and remain fixed. It should be noted that when the display device of the embodiment of the present application is in an unfolded state, the first telescopic part 4, the second telescopic part 5 and the support structure 3 are in the dead point position, and the error directly generates the bending force of the support structure 3. When bending the display device of the embodiment of the present application, a certain external force needs to be applied by the user to make the bending area 32 of the support structure 3 receive an initial bending force, so that the first telescopic part 4 and the second telescopic part 5 are away from the dead point position.

[0044] In the display device of the embodiment of the present application, the first telescopic part 4 and the second telescopic part 5 are arranged at the end of the support structure 3 along the second direction Y, thus the overall thickness of the first display module 1, the second display module 2 and the support structure 3 can be reduced, and further the thickness of the display device of the embodiment of the present application can be reduced. In addition, the first telescopic part 4 and the second telescopic part 5 can adopt the telescopic form, which can reduce the complexity of the display device of the embodiment of the present application and reduce the manufacturing cost.

[0045] Further, referring to Figure 3 and Figure 4 , the first display module 1 includes a first light-out side 11 and a first backlight side 12 opposite to each other, and the first connecting area 31 of the support structure 3 is connected with the first backlight side 12; the second display module 2 includes a second light-out side 21 and a second backlight side 22 opposite to each other, and the second connecting area 33 of the support structure 3 is connected with the second backlight side 22; the display device further includes a first folding state and a second folding state; in the first folding state, at least part of the first display module 1 and at least part of the second display module 2 are located between the first connecting area 31 and the second connecting area 33 of the support structure 3; in the second folding state, at least part of the support structure 3 is located between the first display module 1 and the second display module 2.

[0046] In the embodiment of the present application, the backlight side of the first display module 1 is connected with the first connecting area 31 of the support structure 3, the backlight side of the second display module 2 is connected with the second connecting area 33 of the support structure 3, thereby forming the main structure of the display device of the embodiment of the present application. The display device of the embodiment of the present application comprises a first folding state and a second folding state. In the first folding state, at least part of the first display module 1 and at least part of the second display module 2 are located between the first connecting area 31 and the second connecting area 33 of the support structure 3, that is, the first light exit side 11 of the first display module 1 and the second light exit side 21 of the second display module 2 are arranged towards each other. In the second folding state, at least part of the support structure 3 is located between the first display module 1 and the second display module 2, that is, the first light exit side 11 of the first display module 1 and the second light exit side 21 of the second display module 2 are arranged away from each other.

[0048] Further, referring to Figure 5 , the first telescopic part 4 further comprises a first gear 43 located at the second end 42; the second telescopic part 5 further comprises a second gear 53 located at the fourth end 52, and the support structure 3 further comprises a third gear 34 located at the bending area 32, the axis direction of the third gear 34 being parallel to the second direction Y; the first gear 43 and the second gear 53 are both engaged with the third gear 34.

[0049] The first gear 43 located at the second end 42 is engaged with the third gear 34 of the support structure 3, so that the second end 42 of the first telescopic part 4 can be connected with the support structure 3, and through the engagement of the first gear 43 and the third gear 34, the first telescopic part 4 can maintain the bending state of the support structure 3 when the support structure 3 is bent. Similarly, the second gear 53 located at the fourth end 52 is engaged with the third gear 34 of the support structure 3, so that the fourth end 52 of the second telescopic part 5 can be connected with the support structure 3, and through the engagement of the second gear 53 and the third gear 34, the second telescopic part 5 can maintain the bending state of the support structure 3 when the support structure 3 is bent. That is, the engagement of the first gear 43 and the second gear 53 with the third gear 34 can make the first telescopic part 4 and the second telescopic part 5 maintain the folding and bending state of the first display module 1, the support structure 3 and the second display module 2. Exemplarily, the third gear 34 can penetrate the support structure 3, and the first gear 43 and the second gear 53 are both engaged with the end of the third gear 34.

[0051] Further, please refer to Figure 6 The number of the first stretchable parts 4 is at least two, and at least one first stretchable part 4 is arranged at each end of the support structure 3 along the second direction Y; the number of the second stretchable parts 5 is at least two, and at least one second stretchable part 5 is arranged at each end of the support structure 3 along the second direction Y.

[0052] The first stretchable parts 4 and the second stretchable parts 5 are arranged in at least two groups, that is, at least two groups of the first stretchable parts 4 and the second stretchable parts 5 are arranged at the two ends of the support structure 3 along the second direction Y, and the two groups of the first stretchable parts 4 and the second stretchable parts 5 can provide support for the two ends of the support structure 3 along the second direction Y when the display device of the embodiment is folded and bent, so as to maintain the bending angle of the support structure 3.

[0053] Figure 7 A structural schematic diagram of the support structure of the display device of the embodiment.

[0054] Further, please refer to Figure 7 The bending area 32 is provided with a plurality of hollow parts 35, and the hollow parts 35 penetrate the support structure 3 along the direction perpendicular to the thickness of the support structure 3.

[0055] The bending area 32 of the support structure 3 should have elasticity so as to facilitate the bending of the support structure 3 at the bending area 32. The bending area 32 of the support structure 3 can be made of elastic material. The hollow parts 35 are arranged at the bending area 32 and penetrate the support structure 3, which can make the bending area 32 more easily deformed and reduce the difficulty of folding and bending of the display device of the embodiment on the premise that the structural strength of the bending area 32 in the bending direction is not obviously affected.

[0056] Further, please refer to Figure 7 Along the first direction X, the hollow parts 35 are arranged in at least two rows; and along the first direction X, at least part of the adjacent two rows of hollow parts 35 are not overlapped.

[0057] The hollow parts 35 are arranged in rows and at least two rows of hollow parts 35 are arranged along the first direction X, and the adjacent two rows of hollow parts 35 are not overlapped along the first direction X, that is, the adjacent two rows of hollow parts 35 in the plurality of rows of hollow parts 35 are arranged in staggered manner along the first direction X, so that the bending area 32 of the support structure 3 forms a grid-like shape. Considering that the material of the bending area 32 of the support structure 3 has elasticity, the hollow parts 35 can be deformed when the bending area 32 is bent, so as to reduce the internal stress of the support structure 3, thereby improving the structural stability of the bending area 32.

[0058] Further, please refer to Figure 7The hollow part 35 is in the shape of a rectangle in the thickness direction of the support structure 3, and the rectangle extends along the second direction Y.

[0059] When the display device of the embodiment of the present application is in the unfolded state, the hollow part 35 is in the shape of a rectangle in the thickness direction of the support structure 3, and the rectangle extends along the second direction Y. When the bending area 32 of the support structure 3 is bent, the width direction of the rectangle corresponding to the hollow part 35 can be considered parallel to the tangent of the bending, so the deformation of the hollow part 35 can reduce the internal stress generated when the support structure 3 is bent, and further make the support structure 3 meet the requirement of structural strength.

[0061] Further, referring to Figure 8 Further, the display device of the embodiment of the present application further comprises a non-display module 7; the first display module 1 comprises a first light-emitting side 11 and a first backlight side 12 opposite to each other, and the non-display module 7 is arranged on the first backlight side 12 of the first display module 1, and at least part of the first connecting area 31 is located between the first display module 1 and the non-display module 7.

[0062] In addition to the functions of display and folding, the display device of the embodiment of the present application can also have other functions, and the non-display module 7 can realize the corresponding functions. For example, the non-display module can be a camera module for photographing. In addition, the non-display module 7 can also be used to assist in realizing the display function of the embodiment of the present application. For example, the non-display module 7 can be a battery module for supplying power to the first display module 1 and the second display module 2. The non-display module 7 can be arranged on the first backlight side 12 of the first display module 1. At least part of the first connecting area 31 of the support structure 3 is located between the non-display module 7 and the first display module 1, so as to fully utilize the space of the display device of the embodiment of the present application.

[0065] The display device can further comprise a third display module 6, which can be used as a secondary screen of the display device. The second display module 2 and the third display module 6 are connected together, the third back light side 62 of the third display module 6 and the second back light side 22 of the second display module 2 are arranged opposite to each other, and the third display module 6 and the second display module 2 are arranged opposite to each other, that is, the second display module 2 and the third display module 6 are connected to form a structure that can display light on both sides. At least part of the second connecting area 33 of the support structure 3 is located between the second display module 2 and the third display module 6, so as to reduce the influence of the second connecting area 33 of the support structure 3 on the third display module 6.

[0066] When the display device is in the first folding state, the third display module 6 can display light; when the display device is in the second folding state, the first display module 1 and the second display module 2 can display light respectively; when the display device is in the unfolded state, the first display module 1 and the second display module 2 as a whole can display light, and the third display module 6 can display light or not.

[0067] It should be noted that, continuing to refer to Figure 10 In the present embodiment, the third display module 6 and the non-display module 7 can exist at the same time, at this time, the non-display module 7 is located on the first back light side 12 of the first display module 1, the third display module 6 is located on the second back light side 22 of the second display module 2, the first connecting area 31 of the support structure 3 is located between the first display module 1 and the non-display module 7, and the second connecting area 33 of the support structure 3 is located between the second display module 2 and the third display module 6.

[0072] Further, referring to Figure 12 , the display device of the embodiment of the present application further includes a first controller 81 and a second controller 82, the first controller 81 controls the first telescopic part 4 to be elongated or shortened, and the second controller 82 controls the second telescopic part 5 to be elongated or shortened.

[0073] The first controller 81 can send a first control signal, and the first telescopic part 4 receives the first control signal, so that the first telescopic part 4 is elongated or shortened. Similarly, the second controller 82 can send a second control signal, and the second telescopic part 5 receives the second control signal, so that the second telescopic part 5 is elongated or shortened.

[0074] In the folding and bending of the display device of the embodiment of the present application, the first controller 81 can control the first telescopic part 4 to shorten, and at the same time, the second controller 82 can control the second telescopic part 5 to shorten, so as to serve as the auxiliary power in the folding of the display device of the embodiment of the present application, so that the folding and bending of the display device of the embodiment of the present application is more relaxed and labor-saving. Similarly, in the stretching of the display device of the embodiment of the present application, the first controller 81 can control the first telescopic part 4 to lengthen, and at the same time, the second controller 82 can control the second telescopic part 5 to lengthen, so as to serve as the auxiliary power in the stretching of the display device of the embodiment of the present application, so that the stretching of the display device of the embodiment of the present application is more relaxed and labor-saving. It can be understood that, in order to make the stress of the support structure 3 more uniform, the first telescopic part 4 and the second telescopic part 5 should be synchronously telescoped, so the first controller 81 controls the first telescopic part 4 to telescope, and the second controller synchronously controls the second telescopic part 5 to telescope.

[0075] In summary, the embodiment of the present application provides a display device, the first display module and the second display module are connected with the first connection area and the second connection area of the support structure respectively, so that the display device of the embodiment of the present application can have a folding display function. The first telescopic part and the second telescopic part are both arranged at one end of the support structure along the second direction; the first end of the first telescopic part is connected with the support structure, and the connection is located at the first connection area, and the second end is connected with the support structure, and the connection is located at the bending area; the third end of the second telescopic part is connected with the support structure, and the connection is located at the second connection area, and the fourth end is connected with the support structure, and the connection is located at the bending area. Through the telescoping of the first telescopic part and the second telescopic part, the display device of the embodiment of the present application can be switched between the folded state and the unfolded state. Since the first telescopic part and the second telescopic part are located at the end of the display device along the second direction, the thickness of the first display module, the second display module and the support structure is small, the weight and the cost of the display device are reduced, and the endurance of the battery can be increased under the premise that the thickness of the display device is determined.

[0076] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
