Description

Technical Field

[0002] As a business group that is about to usher in rapid development, smart cars are changing with each passing day. As the link between human-computer interaction in smart cars, in-vehicle displays are an indispensable part of scene innovation. At present, the market demand for rear-seat entertainment displays is also increasing year by year. For display devices in the rear seats of vehicles, there are various forms of changes. One of the most commonly used ones is that the display screen itself is bent to form a concave or convex display screen to adapt to the location or use requirements of the vehicle.

[0003] At present, the bending radius range of the display screen from concave to convex is -R400-R400. For flexible display devices, a supporting structure is usually set in the module to support the entire module. For such a large bending radius range, the supporting structure in the module will make it more difficult to bend the display screen. Utility Model Content

DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] In the related art, refer to Figure 1 As shown, the display module has two bending forms, with the straight state of the display module as the intermediate state. The two bending states can be understood as a concave state and a convex state, respectively. When the display module is applied, the display module can be bent to a concave state and a convex state, respectively, according to the application situation. At present, in the display module, a metal support plate with a thickness of 300 microns to 600 microns is usually used as a support structure, and the metal support plate will generate a large rebound force when bent, resulting in higher requirements for the motor of the bent display module. For example, when the bending radius of the display module is R400, the metal support plate will generate a rebound force of 24N-30N, so the motor needs to output a torque of 80Kg-90Kg, which will cause greater damage to the motor and affect the service life of the motor. Therefore, in the related art, the support structure of the display module will make the bending of the display module more difficult.

[0054] In view of this, the embodiments of the present application propose a support structure, a display module and a display device, by setting a first unit, at least two groups of second units and at least two groups of third units, wherein the two groups of second units are respectively arranged on both sides of the length direction of the first unit, and the two groups of third units are respectively arranged on the side of the two groups of second units away from the first unit, and the second unit and the third unit include a plurality of strip members spaced apart along the first direction, and the strip members extend along the length direction of the first unit; in this way, the first unit, the second unit and the third unit in the support structure can provide a better support effect for the display module, and at the same time, the strip structure formed by the plurality of strip members included in the second unit and the third unit can improve the bending performance of the support structure in the bending direction, thereby making the support structure easier to bend, thereby reducing the difficulty of bending the display module.

[0055] Reference Figure 2 and Figure 3 As shown, a support structure disclosed in an embodiment of the present application is shown. The support structure 20 is applied to the display module 10 to support the entire display module 10. The support structure 20 includes a first unit 21, at least two groups of second units 22 and at least two groups of third units 23.

[0056] Specifically, the first unit 21 is aligned with the bending center line L of the display module 10, and the first unit 21 extends along the bending center line L. In the embodiment of the present application, the display module 10 is a rectangle as a whole, and the bending center line L of the display module 10 is parallel to the short side direction of the display module 10. Among them, the first unit 21 is aligned with the bending center line L of the display module 10, which means that the center line of the first unit 21 itself is aligned with the bending center line L, and the first unit 21 itself has a certain width. The width direction of the first unit 21 is the first direction X, and the first direction X is perpendicular to the length direction of the first unit 21 (that is, the short side direction of the display module 10).

[0057] At least two groups of second units 22 are respectively arranged on both sides of the length direction of the first unit 21, and the second units 22 correspond to the middle area A of the display module 10. The middle area A of the display module 10 refers to a part of the area divided along the first direction X toward the edge of the display module 10 with the bending center line L of the display module 10 as the starting point, and this part of the area is located in the middle position of the display module 10. The two groups of second units 22 are respectively in this area, and together with the first unit 21, they provide support for the middle area A of the display module 10. The size of the middle area A in the first direction X can be greater than or equal to 5mm and less than or equal to 50mm. Exemplarily, the size of the middle area A in the first direction X can be 5mm, 10mm, 20mm, 30mm, 40mm, 50mm, etc., and those skilled in the art can set it according to actual needs.

[0058] At least two groups of third units 23 are respectively arranged on one side of the two groups of second units 22 away from the first unit 21, and the third units 23 correspond to the edge area B of the display module 10. The edge area B of the display module 10 refers to the partial area of ​​the display module 10 at both ends in the first direction X, which is located at the edge of the display module 10, and when the display module 10 is bent, the edge area B of the display module 10 is deformed the most, so the third unit 23 is arranged in this area to provide corresponding support.

[0059] In the embodiment of the present application, there is a transition area between the second unit 22 and the third unit 23. The transition area corresponds to the position between the central area A and the edge area B of the display module 10. It is understandable that the support structure 20 is not provided in the transition area. Therefore, the display module 10 corresponding to the transition area has good flexibility, and the flexibility of the entire support structure 20 is also improved. When the support structure 20 is applied to the display module 10, the support structure 20 is connected to the panel layer 60 of the display module 10 by glue, so the transition area will be filled with glue. The size of the transition area in the first direction X can be greater than or equal to 5mm and less than or equal to 30mm. Exemplarily, the size of the transition area in the first direction X can be 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, etc., and those skilled in the art can set it according to actual needs.

[0060] In order to further improve the flexibility of the support structure 20, refer to Figure 3 As shown, in the embodiment of the present application, the second unit 22 and the third unit 23 are both strip structures, which include a plurality of strip members 30 spaced apart along the first direction X, the strip members 30 extending along the length direction of the first unit 21, and the support structure 20 is not provided in the interval between two adjacent strip members 30, that is, the interval between two adjacent strip members 30 is the same as the transition area, and will be filled with adhesive when connected to the panel layer 60 of the display module 10. In this way, in the first direction X, the second unit 22 and the third unit 23 can be bent better, and whether it is a concave bending or a convex bending, the second unit 22 and the third unit 23 of the strip structure can be deformed more easily. In other words, by using the second unit 22 and the third unit 23 of the strip structure, the rebound force generated by the support structure 20 when it is bent under force can be reduced, thereby reducing the torque required to be output by the motor, thereby reducing damage to the motor and increasing the service life of the motor.

[0061] By means of the above-mentioned support structure 20 provided in the embodiment of the present application, the first unit 21, the second unit 22 and the third unit 23 in the support structure 20 can provide a better support effect for the display module 10. At the same time, the strip structure formed by the multiple strip members 30 included in the second unit 22 and the third unit 23 can improve the bending performance of the support structure 20 in the bending direction, thereby making the support structure 20 easier to bend, thereby reducing the difficulty of bending the display module 10.

[0062] In the embodiment of the present application, the first unit 21, the second unit 22 and the third unit 23 of the support structure 20 can be made of SUS stainless steel or aluminum.

[0063] In one embodiment, the size of the strip 30 in the first direction X is greater than or equal to 0.15 mm and less than or equal to 0.30 mm. The size of the strip 30 in the first direction X can be understood as the width of the strip 30, and the length of the strip 30 is the same as the size of the short side of the display module 10. Exemplarily, the size of the strip 30 in the first direction X can be 0.15 mm, 0.20 mm, 0.25 mm, 0.30 mm, etc., and those skilled in the art can set it according to actual needs.

[0064] In one embodiment, among the plurality of strips 30, the size of the gap between two adjacent strips 30 in the first direction X is greater than or equal to 0.1 mm and less than or equal to 0.5 mm. Exemplarily, the size of the gap between two adjacent strips 30 in the first direction X can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc., and those skilled in the art can set it according to actual needs.

[0065] Meanwhile, it should be noted that, in the strip structure, the sizes of the gaps between two adjacent strip members 30 in the first direction X may be the same or different.

[0066] For example, refer to Figure 3 As shown, in one embodiment, no matter the strip structure of the second unit 22 or the strip structure of the third unit 23 , the gap between two adjacent strip members 30 in the first direction X is 0.2 mm.

[0067] For example, refer to Figure 4 As shown, in one embodiment, in the direction from the middle area to the edge area of ​​the display module 10, in the strip structure of the second unit 22, the gap between two adjacent strip members 30 in the first direction X gradually increases, that is, in the second unit 22, the gap between the strip members 30 closer to the middle area is smaller, and the gap between the strip members 30 closer to the edge area is larger.

[0068] At the same time, in the direction from the middle area to the edge area of ​​the display module 10, in the strip structure of the third unit 23, the gap between two adjacent strip members 30 in the first direction X gradually decreases, that is, in the third unit 23, the gap between the strip members 30 closer to the middle area is larger, and the gap between the strip members 30 closer to the edge area is smaller.

[0069] This arrangement is because when the display module 10 is in a bent state, the degree of deformation of the display module 10 first increases and then decreases from the middle area to the edge area of ​​the display module 10. Therefore, by setting the gap between the strip members 30 according to the degree of deformation, the change in the flexibility of the second unit 22 and the third unit 23 can be made to fit the degree of deformation of the display module 10, thereby making it easier for the display module 10 to deform inward or outward.

[0070] In an optional embodiment, referring to Figure 5 As shown, in order to avoid changes in the positions of the multiple strip members 30 in the strip structures of the second unit 22 and the third unit 23, the embodiment of the present application further provides a support structure 20, in which a plurality of connecting portions 31 are provided between two adjacent strip members 30.

[0071] Specifically, the plurality of connecting parts 31 are spaced apart in the length direction of the first unit 21, and the gaps between two adjacent connecting parts 31 are of the same size in the length direction of the first unit 21. The plurality of connecting parts 31 can provide the strip 30 with a fixed connection relationship, so that during the preparation process, the positions of the strips 30 will not be offset, thereby avoiding the situation where the strips 30 are misplaced. The number, spacing and positions of the connecting parts 31 can be determined according to actual conditions.

[0072] For example, refer to Figure 5 As shown, in one embodiment, three connecting portions 31 are provided between two adjacent strip members 30, and the three connecting portions 31 are evenly spaced along the length direction of the first unit 21, and in the first direction X, the positions of two adjacent connecting portions 31 (for example, the connecting portion 31 between the first strip member 30 and the second strip member 30 and the connecting portion 31 between the second strip member 30 and the third strip member 30) are aligned (it can be understood that, in actual applications, the positions of two adjacent connecting portions 31 are allowed to be within a certain tolerance range).

[0073] For example, refer to Figure 6As shown, in one embodiment, three connecting portions 31 are arranged between two adjacent strip members 30 in the odd array (for example, the first strip member 30 and the second strip member 30, the third strip member 30 and the fourth strip member 30), and two connecting portions 31 are arranged between two adjacent strip members 30 in the even array (for example, the second strip member 30 and the third strip member 30, the fourth strip member 30 and the fifth strip member 30), and, in the first direction X, the positions of two adjacent connecting portions 31 (for example, the connecting portion 31 between the first strip member 30 and the second strip member 30 and the connecting portion 31 between the second strip member 30 and the third strip member 30) are staggered, that is, the positions of two adjacent connecting portions 31 in the first direction X are not aligned; and, in this embodiment, the connecting portion 31 is not arranged in the edge area in the short side direction of the supporting structure 20.

[0074] For example, refer to Figure 7 As shown, in one embodiment, three connecting portions 31 are arranged between two adjacent strip members 30 in the odd array (for example, the first strip member 30 and the second strip member 30, the third strip member 30 and the fourth strip member 30), and two connecting portions 31 are arranged between two adjacent strip members 30 in the even array (for example, the second strip member 30 and the third strip member 30, the fourth strip member 30 and the fifth strip member 30), and, in the first direction X, the positions of two adjacent connecting portions 31 (for example, the connecting portion 31 between the first strip member 30 and the second strip member 30 and the connecting portion 31 between the second strip member 30 and the third strip member 30) are staggered, that is, the positions of two adjacent connecting portions 31 in the first direction X are not aligned; and, in this embodiment, some of the connecting portions 31 are arranged in the edge area in the short side direction of the supporting structure 20.

[0075] In addition, in order to ensure that the position of the strip 30 does not deviate while ensuring the flexibility of the support structure 20, refer to Figure 8 As shown, in the embodiment of the present application, the size of the connecting portion 31 in the light emitting direction Z of the display module 10 is smaller than the size of the strip member 30 in the light emitting direction Z of the display module 10. Among them, the sizes of the connecting portion 31 and the strip member 30 in the light emitting direction Z of the display module 10 can be understood as the thickness of the connecting portion 31 and the strip member 30, respectively. That is to say, in the embodiment of the present application, the thickness of the connecting portion 31 is smaller than the thickness of the strip member 30, so that the strip member 30 can be connected while reducing the impact on the flexibility of the support structure 20. Exemplarily, the thickness of the connecting portion 31 can be 1 / 2 to 1 / 3 of the thickness of the strip member 30 (for example, 1 / 2, 5 / 12, 2 / 5, 5 / 14, 1 / 3, etc.), and those skilled in the art can set it according to actual needs.

[0076] In one embodiment, the dimension of the connecting portion 31 in the length direction of the first unit 21 is greater than or equal to 0.10 mm and less than or equal to 0.20 mm. The dimension of the connecting portion 31 in the length direction of the first unit 21 is also the length of the connecting portion 31. For example, the dimension of the connecting portion 31 in the length direction of the first unit 21 can be 0.10 mm, 0.12 mm, 0.14 mm, 0.16 mm, 0.18 mm, 0.20 mm, etc.

[0077] Based on the same inventive concept, Fig. 9 As shown, an embodiment of the present application further provides a display module, wherein the display module 10 includes a back panel 40 and a display device disposed on one side of the back panel 40 .

[0078] Specifically, the display device includes a stacked support layer 50, a panel layer 60 and a cover layer 70. The support layer 50 can adopt any support structure 20 as described above in the embodiment of the present application, and the support layer 50 and the panel layer 60 are connected by adhesive.

[0079] The panel layer 60 is a device that emits light in the display module 10. When the display module 10 is an OLED (Organic Light-Emitting Diode) display device, the panel layer 60 may specifically include a stacked base substrate, a driving circuit layer, a light-emitting layer, a touch layer, a polarizer layer, and the like.

[0080] The cover layer 70 is the part of the display module 10 that seals the panel layer 60. The cover layer 70 can protect the related devices in the panel layer 60 from being damaged. The cover layer 70 and the panel layer 60 can be connected by OCA (Optically Clear Adhesive) optical glue. The cover layer 70 may include a first cover plate 71 and a second cover plate 72, wherein the first cover plate 71 and the second cover plate 72 are both flexible materials, for example, the first cover plate 71 may be made of UTG (Ultra-Thin Glass) or UFG (Ultra Flexible Glass), and the second cover plate 72 may be made of CPI (transparent polyimide) or PI (polyimide), etc. The first cover plate 71 is connected to the panel layer 60, and the second cover plate 72 is arranged on the side of the first cover plate 71 away from the panel layer 60. The cover plate layer 70 may further include a protective layer 73 . The protective layer 73 is disposed on a side of the second cover plate 72 away from the first cover plate 71 , and the protective layer 73 completely covers the second cover plate 72 .

[0081] Due to the existence of the strip structure in the support structure 20, if the panel layer 60 is directly connected to the support layer 50, it may cause film printing problems on the panel layer 60. Fig.10As shown, in an optional embodiment, the support layer 50 may also include a first support member 51, which is arranged on the side of the support structure 20 away from the back plate 40, and the first support member 51 is connected to the support structure 20 by a glue material, and the orthographic projection of the first support member 51 on the back plate 40 overlaps with the orthographic projection of the support structure 20 on the back plate 40. It should be noted that in this embodiment, the first support member 51 is a planar support structure 20, that is, the first support member 51 can play the role of supporting the entire surface. And the first support member 51 and the support structure 20 can be connected by a glue material with good elasticity (such as PSA (Pressure Sensitive Adhesive) pressure-sensitive adhesive) to avoid film printing during the bonding process. The thickness of the first support member 51 can be 50μm-100μm. For example, the thickness of the first support member 51 can be 50μm, 60μm, 70μm, 80μm, 90μm, 100μm, etc.; the material of the first support member 51 can be stainless steel or aluminum.

[0082] Reference Fig.11 As shown, in one embodiment, the support layer 50 may further include a second support member 52, which is disposed between the back of the support structure 20 and the first support member 51, and the second support member 52 is connected to the support structure 20 and the first support member 51 respectively by adhesive, and the orthographic projection of the second support member 52 on the back plate 40 overlaps with the orthographic projection of the support structure 20 on the back plate 40. It should be noted that, in this embodiment, the second support member 52 is a support structure with a graphic structure.

[0083] For the embodiment of the present application that wants to realize the concave or convex structure of the display module 10, the fixation of each component in the display module 10 is very important. However, since each component in the display module 10 is connected by glue, it is easy for debonding or cracking to occur at the edge of the display module 10 during the concave or convex movement of the display module 10.

[0084] For this purpose, refer to Fig.12 As shown, in an optional implementation, the embodiment of the present application further provides a display module, and the display module 10 also includes a middle frame 80 and a pressure plate 90.

[0085] Specifically, the middle frame 80 is disposed on one side of the back plate 40, the middle frame 80 is disposed along the circumference of the display device, and the middle frame 80 surrounds the display device, and the pressing plate 90 is disposed on the side of the middle frame 80 away from the back plate 40. The pressing plate 90 extends toward the inside of the display device, and the extension length of the pressing plate 90 is determined according to the edge of the panel layer 60 in the display device.

[0086] In this embodiment, the edge of the cover layer 70 of the display device extends toward the middle frame 80 , and finally the orthographic projection of the cover layer 70 on the back plate 40 covers the orthographic projection of the panel layer 60 on the back plate 40 , and the cover layer 70 can extend to contact the middle frame 80 .

[0087] At the same time, the pressing plate 90 is connected to the edge portion of the cover layer 70, and the orthographic projection of the pressing plate 90 on the back plate 40 partially overlaps with the orthographic projection of the panel layer 60 on the back plate 40. It can be understood that during the movement of the display module 10, its force application position is located below the edge of the panel layer 60. Therefore, in the embodiment of the present application, the pressing plate 90 is made to correspond to the edge position of the panel layer 60 (that is, the frame area around the display area in the panel layer 60), and the pressing plate 90 is connected to the cover layer 70. In this way, the pressing plate 90 can give the panel a reaction force above the panel layer 60 to avoid the problem of debonding or degumming of the panel layer 60 due to the lack of pressure from above during the movement.

[0088] It should be noted that in automotive display devices, the border width of the panel layer 60 is approximately 4.0mm-5.0mm. If the border width of the panel layer 60 is less than 4.0mm, it needs to be supplemented to 4.0mm-5.0mm to meet a safe crimping range; illustratively, the border width of the panel layer 60 can be 4.0mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 5.0mm, etc.

[0089] During the movement of the display module 10, since the display device as a whole will bend, there is a shift region between the display area and the frame area of ​​the panel layer 60. The display device in the shift region will deform accordingly when bending, resulting in an increase in size. Similarly, the cover layer 70 corresponding to the shift region also has a corresponding amount of deformation.

[0090] In order to avoid the problem that the cover layer 70 is squeezed by the middle frame 80 due to the deformation of the offset area, refer to Fig.13 As shown, in one embodiment, a gap may be provided between the side of the cover layer 70 and the middle frame 80, and the size of the gap is adapted to the size of the offset region.

[0091] In addition, if the position between the middle frame 80 and the display device is not filled, if cracks appear inside the display device, the spread of the cracks will also affect the service life of the display module 10. Fig.13 As shown, in one embodiment, an elastic material, such as OCA optical glue or PET (polyethylene terephthalate) material, is filled between the middle frame 80 and the display device to provide secondary protection for the display device.

[0092] The display module provided by the embodiment of the present application uses a support structure 20 with a strip structure, which can reduce the difficulty of bending the display module. At the same time, the display device is fixed and protected by the back panel 40, the middle frame 80 and the pressure plate 90, which can increase the service life of the display module.

[0093] Based on the same inventive concept, an embodiment of the present application discloses a display device, comprising any display module as described above in the embodiment of the present application.

[0094] Specifically, the display device may include a computer monitor, a television, a billboard, a laser printer with a display function, a telephone, a mobile phone, a personal digital assistant (PDA), a laptop computer, a digital camera, a camcorder, a viewfinder, a vehicle, a large-area wall, a theater screen, or a stadium sign, etc.

[0095] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0096] It should also be noted that, in this article, the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations, nor can they be understood as indicating or implying relative importance. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. Without more restrictions, an element defined by the phrase "comprising a ..." does not exclude the existence of other identical elements in the process, method, article or terminal device comprising the element.
