[0055] Please refer to Figures 1 to 3 First, it should be noted that the display device 10 of this embodiment can be used in the field of in-vehicle display, such as the display / operation interface of the central control platform 50, but is not limited thereto. In other embodiments, the display device 10 can also be used in other devices that require a human-machine interface.

[0056] In detail, the display device 10 includes a stretchable panel 100 and a plurality of retractable mechanisms 200. The stretchable panel 100 has an operating surface 100s, and these retractable mechanisms 200 are arranged on the side of the stretchable panel 100 facing away from the operating surface 100s. For example, in this embodiment, the stretchable panel 100 may include a plurality of island structures (not shown) having a display function or a touch function and a bridging structure (not shown) connected between these island structures. The spacing between these island structures changes as the stretchable panel 100 operates in different deformation states. The stretchable panel 100 can be a display panel, a touch panel, or a combination thereof.

[0057] For example, in this embodiment, the plurality of retractable mechanisms 200 may be arranged in a spaced arrangement along directions X and Y, where directions X and Y intersect and are perpendicular to direction Z. More specifically, the retractable mechanisms 200 are arranged in a honeycomb pattern along the normal direction (e.g., direction Z) of the operating surface 100s of the stretchable panel 100. However, the present invention is not limited thereto. In other embodiments, the arrangement and distribution of the retractable mechanisms 200 may be adjusted accordingly based on the actual application of the visual display device.

[0058] In this embodiment, the plurality of telescopic mechanisms 200 are each abutted against the back surface 100bs of the stretchable panel 100 facing away from the operating surface 100s, and are adapted to drive the stretchable panel 100 to deform along a direction (e.g., direction Z) intersecting the operating surface 100s. More specifically, the telescopic mechanism 200 is used to drive a portion of the stretchable panel 100 to be recessed toward the side facing away from the operating surface 100s (e.g., Figure 6A ), or driving a portion of the stretchable panel 100 to bulge toward one side of the operating surface 100s (as shown Figure 6B The aforementioned part of the stretchable panel 100 is, for example, a portion where the stretchable panel 100 is connected to each telescopic mechanism 200 .

[0059] Please refer to Figure 3 and Figure 4The stretchable panel 100 may include a first panel 111, a first stretchable film 121, a second stretchable film 122, a first adhesive layer 131, and a second adhesive layer 132. In this embodiment, the first stretchable film 121 and the second stretchable film 122 are respectively disposed on opposite sides of the first panel 111. The first adhesive layer 131 connects the first panel 111 and the first stretchable film 121. The second adhesive layer 132 is disposed on a side of the first panel 111 facing away from the first stretchable film 121 and connects the first panel 111 and the second stretchable film 122.

[0060] More specifically, the first stretchable film 121 is attached to one surface of the first panel 111 via a first adhesive layer 131, while the second stretchable film 122 is attached to the other surface of the first panel 111 via a second adhesive layer 132. In this embodiment, the surface of the first stretchable film 121 facing away from the first panel 111 can be defined as the operating surface 100s of the stretchable panel 100, but is not limited thereto. In this embodiment, the retractable mechanism 200 is adapted to deform the stretchable panel 100 along the stacking direction (e.g., direction Z) of the first panel 111, the first stretchable film 121, the second stretchable film 122, the first adhesive layer 131, and the second adhesive layer 132.

[0061] In the stacking direction of the aforementioned multiple film layers, the first panel 111, the first adhesive layer 131, and the second adhesive layer 132 have thicknesses 111t, 131t, and 132t, respectively. In this embodiment, the thickness 131t of the first adhesive layer 131 and the thickness 132t of the second adhesive layer 132 may be greater than the thickness 111t of the first panel 111. For example, the thickness 111t of the first panel 111 may be 20 μm, while the thicknesses of the first adhesive layer 131 and the second adhesive layer 132 may each be 50 μm. Because the first panel 111 is very thin, the first and second stretchable films 121, 122 attached to opposite sides of the first panel 111 can provide protection for the first panel 111.

[0062] On the other hand, the first panel 111 may be provided with the aforementioned multiple island structures having display or touch functions, as well as bridge structures connecting these island structures. In this embodiment, the Young's modulus of the first panel 111 is preferably less than 100 MPa. In other words, the first panel 111 of this embodiment has stretchability.

[0063] Specifically, the Young's modulus of each of the first stretchable film 121, the second stretchable film 122, the first adhesive layer 131, and the second adhesive layer 132 is less than the Young's modulus of the first panel 111. More specifically, the ratio of the Young's modulus of the first panel 111 to the Young's modulus of each of the first adhesive layer 131 and the second adhesive layer 132 is greater than or equal to 1000. For example, in this embodiment, the Young's modulus of the first panel 111 is 10 MPa, the Young's modulus of the first adhesive layer 131 and the second adhesive layer 132 is 0.01 MPa, the Young's modulus of the first stretchable film 121 is 3 MPa, and the Young's modulus of the second stretchable film 122 is 2.5 MPa, but the present invention is not limited thereto.

[0064] Since the ratio of the Young's modulus of the first panel 111 to the adhesive layer is greater than or equal to 1000, when the stretchable panel 100 is deformed by force, the maximum strain generated is concentrated on the first adhesive layer 131 and the second adhesive layer 132 rather than the first panel 111. Therefore, the deformation capability of the display device 10 can be significantly improved, for example, the stretchable panel 100 can be increased in the following situations: Figure 6A The depth of the depression in the deformation, or in the Figure 6B The height of the bulge in the deformation.

[0065] Preferably, the ratio of the Young's modulus of the first panel 111 to the Young's modulus of the first adhesive layer 131 and the second adhesive layer 132 is less than or equal to 105. This can prevent the yield of the bonding process of the stretchable film to the first panel 111 from being affected by the low Young's modulus of the adhesive layer.

[0066] Please refer to Figure 5 In another embodiment, the stretchable panel 100A may further include a second panel 112, a third stretchable film 123, a third adhesive layer 133, and a fourth adhesive layer 134. The second panel 112 is disposed on a side of the second stretchable film 122 facing away from the first panel 111. The third stretchable film 123 is disposed on a side of the second panel 112 facing away from the first panel 111. The third adhesive layer 133 connects the second panel 112 and the second stretchable film 122. The fourth adhesive layer 134 is disposed on a side of the second panel 112 facing away from the first panel 111 and connects the third stretchable film 123 and the second panel 112. More specifically, the second stretchable film 122 is attached to one surface of the second panel 112 via the third adhesive layer 133, and the third stretchable film 123 is attached to the other surface of the second panel 112 via the fourth adhesive layer 134.

[0067] In the stacking direction of the aforementioned multiple film layers, the second panel 112, the third adhesive layer 133, and the fourth adhesive layer 134 have thicknesses 112t, 133t, and 134t, respectively. In this embodiment, the thickness 133t of the third adhesive layer 133 and the thickness 134t of the fourth adhesive layer 134 may be greater than the thickness 112t of the second panel 112. For example, the thickness 112t of the second panel 112 may be 20 μm, while the thicknesses of the third adhesive layer 133 and the fourth adhesive layer 134 may each be 50 μm. Because the second panel 112 is very thin, the second and third stretchable films 122 and 123 attached to opposite sides of the second panel 112 can provide protection for the second panel 120.

[0068] In this embodiment, the first panel 111 may be provided with the aforementioned multiple island structures with touch functionality and a bridge structure connecting these island structures, while the second panel 112 may be provided with the aforementioned multiple island structures with display functionality and a bridge structure connecting these island structures. In this embodiment, the Young's modulus of each of the first panel 111 and the second panel 112 is preferably less than 100 MPa. In other words, both the first panel 111 and the second panel 112 of this embodiment have stretchability.

[0069] Specifically, the Young's modulus of each of the second stretchable film 122, the third stretchable film 123, the third adhesive layer 133, and the fourth adhesive layer 134 is less than the Young's modulus of the second panel 112. More specifically, the ratio of the Young's modulus of the second panel 112 to the Young's modulus of each of the third adhesive layer 133 and the fourth adhesive layer 134 is greater than or equal to 1000. For example, in this embodiment, the Young's modulus of each of the first panel 111 and the second panel 112 is 10 MPa, the Young's modulus of each of the first adhesive layer 131, the second adhesive layer 132, the third adhesive layer 133, and the fourth adhesive layer 134 is 0.01 MPa, the Young's modulus of the first stretchable film 121 is 3 MPa, and the Young's modulus of each of the second stretchable film 122 and the third stretchable film 123 is 2.5 MPa, but the present invention is not limited thereto.

[0070] Since the ratio of the Young's modulus of the second panel 112 to the adhesive layer is greater than or equal to 1000, when the stretchable panel 100 is deformed by force, the maximum strain generated is concentrated on the third adhesive layer 133 and the fourth adhesive layer 134 rather than the second panel 112. Therefore, the deformation capacity of the display device can be significantly improved, for example, the stretchable panel 100A can be increased in the following situations: Figure 6A The depth of the depression in the deformation, or in the Figure 6B The height of the bulge in the deformation.

[0071] Preferably, the ratio of the Young's modulus of the second panel 112 to the Young's modulus of the third adhesive layer 133 and the fourth adhesive layer 134 is less than or equal to 105. This can prevent the yield of the bonding process of the stretchable film to the second panel 112 from being affected by the low Young's modulus of the adhesive layer.

[0072] In summary, in the display device and central control platform of one embodiment of the present invention, the first stretchable film is attached to one side of the first panel via the first adhesive layer. Because the ratio of the Young's modulus of the first panel to the Young's modulus of the first adhesive layer is greater than or equal to 1000, the deformation capability of the display device is significantly improved, and the deformation stability is also improved.
