With reference to Figures 1, 2 to 3, a display device 10 of the present embodiment can be used in the area of ​​vehicle-internal displays, such as a display / operating interface of a central control platform 50, but the disclosure is not limited thereto. In other embodiments, the display device 10 can also be used in other devices that require a human-machine interface. Specifically, the display device 10 comprises a stretchable panel 100 and a plurality of telescopic mechanisms 200. The stretchable panel 100 has an operating area 100s, and the telescopic mechanisms 200 are arranged on a side of the stretchable panel 100 facing away from the operating area 100s. In this embodiment, the stretchable panel 100 can, for example, include a plurality of island structures (not shown) with a display function or a touch function and a bridge structure (not shown) connected between these island structures. The distance between these island structures changes when 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. In this embodiment, the plurality of telescopic mechanisms 200 can, for example, be arranged at intervals along a direction X and a direction Y, wherein direction X and direction Y intersect and are perpendicular to a direction Z. More precisely, these telescopic mechanisms 200 are arranged in a honeycomb pattern in a normal direction (e.g., direction Z) of the operating surface 100s of the extendable panel 100. However, the disclosure is not limited to this. In other embodiments, the arrangement of these telescopic mechanisms 200 can be adapted depending on the actual application of the display device. In this embodiment, each of the multiple telescopic mechanisms 200 can bear against a rear surface 100bs of the stretchable panel 100, which faces away from the operating surface 100s, and is designed to drive the stretchable panel 100 so that it deforms along a direction (e.g., direction Z) that intersects the operating surface 100s. More precisely, the telescopic mechanism 200 is used to deform a portion of the stretchable panel 100 inward toward a side facing away from the working surface 100s (as shown in Fig. 6A), or to deform a portion of the stretchable panel 100 outward toward a side of the working surface 100s (as shown in Fig. 6B). The aforementioned section of the stretchable panel 100 is, for example, a section at which the stretchable panel 100 is connected to each telescopic mechanism 200. Referring to Figures 3 and 4, the stretchable sheet 100 can comprise a first sheet 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 arranged on opposite sides of the first sheet 111. The first adhesive layer 131 bonds the first sheet 111 and the first stretchable film 121. The second adhesive layer 132 is arranged on a side of the first sheet 111 facing away from the first stretchable film 121 and bonds the first sheet 111 and the second stretchable film 122. More precisely, the first stretchable film 121 is attached to one side surface of the first panel 111 via the first adhesive layer 131, and the second stretchable film 122 is attached to the other side surface of the first panel 111 via the 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 the disclosure is not limited thereto. In this embodiment, the telescopic mechanism 200 is suitable for driving the stretchable panel 100 such that it deforms along a 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. In the stacking direction of the aforementioned multiple film layers, the first sheet 111, the first adhesive layer 131, and the second adhesive layer 132 have thicknesses of 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 can be greater than the thickness 111t of the first sheet 111. For example, the thickness 111t of the first sheet 111 can be 20 µm, and the thicknesses of the first adhesive layer 131 and the second adhesive layer 132 can each be 50 µm. Since the first sheet 111 is relatively thin, the first stretchable film 121 and the second stretchable film 122, which are attached to opposite sides of the first sheet 111, can provide a protective effect for the first sheet 111. On the other hand, the first panel 111 can be provided with the aforementioned multiple island structures, which have a display or touch function, and with a bridge structure connected between these island structures. In this embodiment, the elastic modulus of the first panel 111 can preferably be less than 100 MPa. That is, the first panel 111 of this embodiment has extensibility. It is particularly emphasized that the modulus of elasticity 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 lower than the modulus of elasticity of the first sheet 111. More precisely, the ratio of the modulus of elasticity of the first sheet 111 to the modulus of elasticity of the first adhesive layer 131 and the second adhesive layer 132 is greater than or equal to 1000. In the embodiment, for example, the modulus of elasticity of the first sheet 111 is 10 MPa, the modulus of elasticity of the first adhesive layer 131 and the second adhesive layer 132 is 0.01 MPa each, the modulus of elasticity of the first stretchable film 121 is 3 MPa, and the modulus of elasticity of the second stretchable film 122 is 2.5 MPa, but the disclosure is not limited thereto. Since the ratio of the elastic modulus of the first panel 111 to the adhesive layer is greater than or equal to 1000, the resulting maximum strain is concentrated in the first adhesive layer 131 and the second adhesive layer 132, and not in the first panel 111, when the stretchable panel 100 is deformed under force. Therefore, the deformability of the display device 10 can be significantly improved, for example, by increasing the indentation depth of the stretchable panel 100 during the deformation shown in Fig. 6A or the projection height during the deformation shown in Fig. 6B. Preferably, the ratio of the modulus of elasticity of the first sheet 111 to the modulus of elasticity of the first adhesive layer 131 and the second adhesive layer 132 is less than or equal to 105. Accordingly, the adhesive strength of the stretchable film on the first sheet 111 can be prevented from being impaired by the low modulus of elasticity of the adhesive layer. Referring to Fig. 5, in another embodiment a stretchable sheet 100A can further comprise a second sheet 112, a third stretchable film 123, a third adhesive layer 133, and a fourth adhesive layer 134. The second sheet 112 is arranged on a side of the second stretchable film 122 facing away from the first sheet 111. The third stretchable film 123 is arranged on a side of the second sheet 112 facing away from the first sheet 111. The third adhesive layer 133 bonds the second sheet 112 and the second stretchable film 122. The fourth adhesive layer 134 is arranged on a side of the second sheet 112 facing away from the first sheet 111 and bonds the third stretchable film 123 and the second sheet 112.More precisely, the second stretchable film 122 is attached to one side surface of the second panel 112 via the third adhesive layer 133, and the third stretchable film 123 is attached to the other side surface of the second panel 112 via the fourth adhesive layer 134. In one stacking direction of the aforementioned multiple film layers, the second sheet 112, the third adhesive layer 133, and the fourth adhesive layer 134 have thicknesses of 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 can be greater than the thickness 112t of the second sheet 112. For example, the thickness 112t of the second sheet 112 can be 20 µm, and the thicknesses of the third adhesive layer 133 and the fourth adhesive layer 134 can each be 50 µm. Since the second sheet 112 is relatively thin, the second stretchable film 122 and the third stretchable film 123, which are attached to opposite sides of the second sheet 112, can provide a protective effect for the second sheet 120. In this embodiment, the first panel 111 can be provided with the aforementioned multiple island structures with contact functions and a bridge structure connecting these island structures, and the second panel 112 can be provided with the aforementioned multiple island structures with display functions and a bridge structure connecting these island structures. In this embodiment, the modulus of elasticity of each of the first panel 111 and the second panel 112 is preferably less than 100 MPa. That is, both the first panel 111 and the second panel 112 of this embodiment are stretchable. It is particularly emphasized that the modulus of elasticity 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 lower than the modulus of elasticity of the second panel 112. More precisely, the ratio of the modulus of elasticity of the second panel 112 to the modulus of elasticity of the third adhesive layer 133 and the fourth adhesive layer 134 is greater than or equal to 1000. In the embodiment, for example, the modulus of elasticity of the first panel 111 and the second panel 112 is 10 MPa each, the modulus of elasticity 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 each, the modulus of elasticity of the first stretchable film 121 is 3 MPa, and the modulus of elasticity of the second stretchable film 122 and the third stretchable film 123 is [missing information]. 2.5 MPa, but the revelation is not limited to that. Since the ratio of the elastic modulus of the second panel 112 to the adhesive layer is greater than or equal to 1000, the resulting maximum strain is concentrated in the third adhesive layer 133 and the fourth adhesive layer 134, and not in the second panel 112, when the stretchable panel 100 is deformed under force. Therefore, the deformability of the display device can be significantly improved, for example, by increasing the indentation depth of the stretchable panel 100A during the deformation shown in Fig. 6A or the projection height during the deformation shown in Fig. 6B. Preferably, the ratio of the elastic modulus of the second sheet 112 to the elastic modulus of the third adhesive layer 133 and the fourth adhesive layer 134 is less than or equal to 105. Accordingly, the adhesive performance of the stretchable film on the second sheet 112 can be prevented from being impaired by the low elastic modulus of the adhesive layer. In summary, in a display device according to one embodiment of the disclosure, a first stretchable film is attached to one side of a first panel over a first adhesive layer. Since the ratio of the elastic modulus of the first panel to that of the first adhesive layer is greater than or equal to 1000, the deformability of the display device is significantly improved, and the stability of the deformation is also increased. It will be clear to those skilled in the art that various modifications and variations can be made to the disclosed embodiments without departing from the scope or spirit of the disclosure. In light of the foregoing, it is intended that the disclosure includes modifications and variations, provided that they fall within the scope of the following claims and their equivalents.
