Therefore, this application is intended to cover modifications and variations of this application that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the embodiments provided in the examples of this application can be combined with each other without contradiction.

[0044] The integration of digital functionality into automotive interior materials is attracting increasing attention. Existing technologies integrate translucent surface materials into vehicle displays, integrating lighting, sensing, touch, and other functions to create smart surfaces. These surfaces transform vehicle displays into stylish decorative surfaces, combining both decorative and functional qualities. Current vehicle surfaces present two major challenges: They are flat and smooth with textures, addressing only the appearance of the display's integration with the environment. Alternatively, they offer a tactile feel but lack sufficient transmittance to achieve the desired display quality, or they increase power consumption to achieve the desired display quality, failing to achieve both visual and tactile integration with the environment.

[0045] In order to solve the above problems, the present invention provides a tactile surface skin, a method for preparing the tactile surface skin and a display device. Figures 1 to 5 Various embodiments of a tactile skin, a method for preparing the tactile skin, and a display device are described.

[0046] Figure 1is a top view of a tactile surface provided by an embodiment of the present invention, Figure 2 An embodiment provides Figure 1 One of the cross-sectional structural diagrams at point A in the middle, Figure 3 An embodiment provides Figure 1 The second schematic diagram of the cross-sectional structure at point A in the middle.

[0047] See also Figures 1 to 3 An embodiment of the present application provides a tactile surface, comprising: a sensing layer 400 and a tactile layer 600. The sensing layer 400 includes a deformable portion 500. The tactile layer 600 is located on one side of the sensing layer 400 and has a first state and a second state. The deformable portion 500 is configured to deform along a first direction X and drive a portion of the tactile layer 600 to deform along a side away from the sensing layer 400 to form a protrusion 610, thereby transitioning the tactile layer 600 from the first state to the second state. The first direction X intersects the plane of the sensing layer 400.

[0048] It should be noted that the first direction refers to the vertical direction, that is, Figure 1 The direction indicated by the arrow.

[0049] Optional, Figure 2 It can be the first state, Figure 3 It can be the second state. Under the drive of the deformation part 500, the touch layer 600 can be Figure 2 The first state changes to Figure 3 , thereby forming protrusions 610 on the surface of the touch sensing layer 600 .

[0050] In the tactile surface provided in the embodiment of the present application, the tactile surface comprises a sensing layer 400 and a tactile layer 600. The sensing layer 400 comprises a deformable portion 500, and the deformable portion 500 is configured to deform along a first direction X to support the tactile layer 600. The tactile layer 600 is located on one side of the sensing layer 400 and comprises a first state and a second state, wherein, as Figure 2 As shown, when the touch layer 600 is in the first state, the surface of the touch layer 600 tends to be flat and smooth, which can reduce its impact on light emission and meet the requirement that the touch surface has sufficient transmittance. Figure 3As shown, when the touch-sensitive layer 600 is in the second state, protrusions 610 with a textured tactile feel are formed on its surface. The deformable portion 500 is configured to deform along a first direction X and cause a portion of the touch-sensitive layer 600 to deform along a side facing away from the sensing layer 400 to form the protrusions 610, thereby transitioning the touch-sensitive layer 600 from the first state to the second state. The first direction X intersects the plane of the sensing layer 400. In this embodiment of the present application, the touch-sensitive layer 600 in the first state can meet the requirement of sufficient transmittance for the tactile surface, while the touch-sensitive layer 600 in the second state can meet the requirement of a textured tactile feel that adapts to the environment. This achieves compatibility between light transmittance, appearance, and tactile feel that blends in with the environment, thereby enhancing the display effect.

[0051] In some optional embodiments, the sensing layer 400 further includes a sensor 440 for acquiring status information. The deforming portion 500 is configured to deform along the first direction X according to the status information and drive a portion of the touch layer 600 to deform along a side away from the sensing layer 400 to form a protrusion 610.

[0052] In these optional embodiments, the sensor 440 is used to obtain status information, such as status information including proximity information of a user's finger. The sensor 440 can be used to receive the finger position and proximity status information. The deformable portion 500 is configured to deform along a first direction X based on the status information. For example, the deformable portion 500 can be an electromagnetic portion 510. The electromagnetic portion 510 is energized based on the status information, thereby controlling the magnetism of the electromagnetic portion 510, causing at least a portion of the touch-sensitive layer 600 to deform along the first direction X toward the side away from the sensing layer 400 to form a protrusion 610, thereby changing the surface flatness and roughness of the touch-sensitive layer 600, producing a textured tactile effect.

[0053] Optionally, when the finger leaves the sensor 440 and the sensor 440 does not obtain the information state, the electromagnetic part 510 can be powered off or the current direction can be changed, so that the electromagnetic parts 510 are close to each other along the first direction X, so that the touch layer 600 is changed from the second state to the first state, and the touch layer 600 is restored to a flat state, thereby ensuring the transmittance of the touch surface when the user's finger does not touch the touch layer 600.

[0054] In the embodiment of the present application, the user can completely integrate with the surrounding environment when not touching the touch layer 600, and can also have obvious touch when the user's finger approaches, achieving the effect of true environmental integration.

[0055] In some optional embodiments, the deformation portion 500 includes two electromagnetic portions 510 arranged opposite to each other along the first direction X. The two electromagnetic portions 510 are used to generate a repulsive force to move away from each other and drive the touch layer 600 to deform at least partially toward the side away from the sensing layer 400 to form a protrusion 610.

[0056] In these optional embodiments, the two electromagnetic portions 510 have the same magnetic properties, thereby generating a repulsive force, so that the two electromagnetic portions 510 move away from each other and drive the touch-sensitive layer 600 to deform at least partially toward the side away from the sensing layer 400 to form a protrusion 610, thereby changing the surface flatness and roughness of the touch-sensitive layer 600 and producing a textured tactile effect.

[0057] In some optional embodiments, the sensing layer 400 includes a first sublayer 410 and a second sublayer 420 arranged opposite to each other along the first direction X, and the two electromagnetic parts 510 are respectively arranged in the first sublayer 410 and the second sublayer 420, and the first sublayer 410 is located on the side of the second sublayer 420 close to the touch layer 600.

[0058] In these optional embodiments, the electromagnetic parts 510 are disposed in the first sub-layer 410 and the second sub-layer 420 that are opposite to each other along the first direction X. Thus, when the two electromagnetic parts 510 move away from each other along the first direction X, they drive at least a portion of the touch-sensitive layer 600 to deform along the first direction X toward the side away from the sensing layer 400 to form a protrusion 610, thereby changing the surface flatness and roughness of the touch-sensitive layer 600 and producing a textured tactile effect.

[0059] Optionally, the first sub-layer 410 and the second sub-layer 420, which are opposite to each other along the first direction X, are respectively provided with an electromagnetic portion 510. The electromagnetic portions 510 are grouped together. By moving away from each other along the first direction X, the same group of electromagnetic portions can drive at least a portion of the touch-sensitive layer 600 to deform along the first direction X toward a side away from the sensing layer 400 to form a protrusion 610, thereby changing the surface flatness and roughness of the touch-sensitive layer 600 and producing a textured tactile effect.

[0060] Optionally, the location of the sensor 440 is not particularly limited, as long as it is at a location that can be sensed by the user's finger.

[0061] In some optional embodiments, the sensing layer 400 further includes a flexible film layer 430, the electromagnetic portion 510 is disposed within the flexible film layer 430, and the touch layer 600 is disposed on a surface of the first sub-layer 410 corresponding to the electromagnetic portion 510 facing away from the second sub-layer 420. The two electromagnetic portions 510 move away from each other and drive the flexible film layer 430 to deform toward a side closer to the touch layer 600, thereby causing the touch layer 600 to at least partially deform toward a side facing away from the sensing layer 400 to form a protrusion 610, thereby causing the touch layer 600 to transition from the first state to the second state.

[0062] Optionally, the touch layer 600 is configured to be attached to the light-emitting side of the display panel, and the first sublayer 410 is located on the side of the second sublayer 420 that is away from the light-emitting side. It can be understood that the first sublayer 410 is located on the side of the second sublayer 420 that is away from the light-emitting functional layer 300 to achieve the display and touch simulation functions of the display panel.

[0063] In these optional embodiments, the electromagnetic part 510 is arranged in the flexible film layer 430, that is, the electromagnetic part 510 is covered by the flexible film layer 430, and the flexible film layer 430 can be a soft rubber layer, wherein the touch layer 600 can be arranged on the surface of the electromagnetic part 510, so that when the electromagnetic part 510 moves away from each other, it can move a small range to drive the flexible film layer 430 to deform toward the side close to the touch layer 600.

[0064] Optionally, the flexible membrane layer 430 includes at least one of silicone and thermoplastic polyurethane elastomer. The above material has strong wrapping properties and good scalability, and can protect the electromagnetic part 510 and improve its service life.

[0065] Optionally, the thickness of the flexible film layer 430 can be 1μm to 100μm. The thickness of the flexible film layer 430 can be 1μm, 25μm, 50μm, 75μm, or 100μm, which can improve the problem of insufficient layout space caused by the flexible film layer 430 being too thin, and can also improve the problem of increased thickness of the display panel caused by the flexible film layer 430 being too thick.

[0066] In some optional embodiments, such as Figure 4 and Figure 5 As shown, the electromagnetic part 510 includes a microcircuit structure 511, and the microcircuit structure 511 is a spiral structure.

[0067] Optionally, the touch-sensitive layer 600 changes from the first state to the second state, and the two microcircuit structures 511 are arranged away from each other.

[0068] In these optional embodiments, the microcircuit structure 511 with a spiral structure can generate a magnetic field after being energized, thereby providing power to move the electromagnetic part 510 along the first direction X.

[0069] Optionally, the microcircuit structure 511 of the first sublayer 410 and the microcircuit structure 511 of the second sublayer 420 rotate in opposite directions, so that the microcircuit structure 511 of the first sublayer 410 and the microcircuit structure 511 of the second sublayer 420 generate magnetic forces in opposite directions.

[0070] Optionally, in the two electromagnetic portions 510 spaced apart along the first direction X of the deformable portion 500, at least one of the microcircuit structures 511 corresponding to each electromagnetic portion 510 is provided with an inductive switch 540. For example, in a deformable portion 500, the electromagnetic portion 510 located in the first sublayer 410 may be provided with an inductive switch 540, while the electromagnetic portion 510 located in the second sublayer 420 may not be provided with an inductive switch 540. Alternatively, in a deformable portion 500, the electromagnetic portion 510 located in the first sublayer 410 may not be provided with an inductive switch 540, while the electromagnetic portion 510 located in the second sublayer 420 may be provided with an inductive switch 540. Alternatively, in a deformable portion 500, both the electromagnetic portion 510 located in the first sublayer 410 and the electromagnetic portion 510 located in the second sublayer 420 may be provided with an inductive switch 540. The induction switch 540 is used to control whether the microcircuit structure 511 at the corresponding position is energized after the sensor 440 obtains status information. The induction switch 540 can simultaneously control whether the microcircuit structures 511 of the two electromagnetic parts 510 in the deformation part 500 are energized, or the induction switch 540 can separately control whether the microcircuit structures 511 of the two electromagnetic parts 510 in the deformation part 500 are energized.

[0071] Optionally, when the tactile layer 600 transitions from the first state to the second state, the inductive switch 540 is used to enable the sensor 440 to obtain state information. For example, after obtaining the finger's position information, the sensor 440 controls the microcircuit structure 511 at the corresponding position to energize, causing the corresponding electromagnetic portion 510 to deform in the first direction X and driving a portion of the tactile layer 600 to deform along the side facing away from the inductive layer 400, forming a protrusion 610. This allows for independent control of the electromagnetic portion 510 within the range touched by the user's finger. While the protrusion 610 is formed within the range touched by the user's finger, the tactile surface in the remaining area still maintains the required light transmittance, achieving compatibility between tactile and light transmittance. Optionally, the electromagnetic portion 510 further includes a magnetic core 512. The microcircuit structure 511 is disposed around and connected to the magnetic core 512. The magnetic core 512 can further enhance the magnetic properties of the spiral microcircuit structure 511, thereby providing the required power to drive the electromagnetic portion 510.

[0072] Optionally, the material of the magnetic core 512 includes at least one of iron oxide film, ferrite, and zinc oxide nanocomposite material.

[0073] Optionally, the electromagnetic part 510 further includes an insulating film 513 , which covers at least a portion of the microcircuit structure 511 to reduce the problem of short circuit of the microcircuit structure 511 and improve the service life of the electromagnetic part 510 .

[0074] In some optional embodiments, in the same first sublayer 410 and / or second sublayer 420 , there are multiple electromagnetic parts 510 , the multiple electromagnetic parts 510 are arranged at intervals, and the microcircuit structures 511 between adjacent electromagnetic parts 510 are interconnected through stretchable traces 530 .

[0075] In these optional embodiments, the plurality of electromagnetic portions 510 are spaced apart, and the microcircuit structures 511 between adjacent electromagnetic portions 510 are interconnected via stretchable traces 530, thereby enabling the magnetism of the plurality of electromagnetic portions 510 to be changed simultaneously. The plurality of electromagnetic portions 510 can simultaneously move away from each other and drive the flexible membrane layer 430 to deform toward the side close to the touch layer 600, thereby driving the touch layer 600 to at least partially deform toward the side away from the sensing layer 400 to form a protrusion 610, thereby reducing the possibility of the stretchable traces 530 being broken during the process of the touch layer 600 transitioning from the first state to the second state.

[0076] In some optional embodiments, the stretchable trace 530 extends along a wavy, tortuous path.

[0077] In these optional embodiments, the stretchable traces 530 extend along a wavy, curved path, further reducing the possibility of the stretchable traces 530 being broken during the transition of the tactile layer 600 from the first state to the second state. Optionally, different tactile sensations can be achieved using the microcircuit structure 511. That is, by adjusting the microcircuit structure 511 to different sizes and paths, different tactile sensations can be achieved. Surface tactile sensations include, but are not limited to, leather, wood grain, fabric, glass, and plastic. The surface of the tactile layer 600 facing away from the substrate 100 includes, but is not limited to, a diffusely reflective matte surface, a reflective glossy surface, and the like.

[0078] Optionally, the material of the touch layer 600 includes at least one of polyethylene terephthalate (PET), acrylonitrile butadiene styrene copolymer (ABS), polycarbonate (PC), polymethyl methacrylate (PMMA), and silicone. Different materials can be selected according to the desired tactile sensation.
