Description

[Technical Field]

[0001] This invention relates to a panel and a display, and more particularly to a stretchable panel and an in-vehicle display. [Previous Technology]

[0002] With the rapid development of electronic technology, electronic products are constantly being innovated. To enable electronic products to be applied in various fields, the characteristics of stretchability, thinness, and unrestricted shape are increasingly valued. In other words, electronic products are increasingly required to have different shapes depending on the application method and environment; therefore, electronic products need to be stretchable. However, when electronic products are stretched, the connection between the stretchable traces and electronic components may experience structural fracture due to excessive stress, leading to open circuits. Therefore, how to improve the reliability of electronic products under stretching operations remains an urgent issue to be addressed. [Summary of the Invention]

[0003] The present invention provides a stretchable panel, wherein the strain generated when stretched will be away from the connection between the conductor and the island element, so as to ensure the electrical connection between the conductor and the island element in the stretched state.

[0004] The stretchable panel of the present invention includes a first island element, a second island element, an organic pattern, and a conductive wire. The first island element and the second island element each have an inorganic pattern. The organic pattern connects the first island element and the second island element and has a stretchable portion and a non-stretchable portion. The stretchable portion connects the edges of the inorganic patterns of the first island element and the second island element. The non-stretchable portion extends from the stretchable portion and covers the surface of the inorganic pattern. The conductive wire is disposed on the organic pattern and electrically connects the first island element and the second island element. The edge of the inorganic pattern defines the boundary between the stretchable portion of the inorganic pattern and the organic pattern on a virtual plane perpendicular to the stacking direction of the organic pattern and the conductive wire. The conductive wire has a first straight line segment crossing the boundary, and the first straight line segment has an angle greater than 0 degrees between itself and a first virtual straight line perpendicular to the boundary on the virtual plane.

[0005] The vehicle-mounted display of the present invention includes a stretchable panel. The stretchable panel is disposed on a vehicle central control platform and includes a first island element, a second island element, an organic pattern, and a conductor. The first island element and the second island element each have an inorganic pattern. The organic pattern connects the first island element and the second island element and has a stretchable portion and a non-stretchable portion. The stretchable portion connects the edges of the inorganic patterns of the first island element and the second island element. The non-stretchable portion extends from the stretchable portion and covers the surface of the inorganic pattern. The conductor is disposed on the organic pattern and electrically connects the first island element and the second island element. The edge of the inorganic pattern defines the boundary between the stretchable portion of the inorganic pattern and the organic pattern on a virtual plane perpendicular to the stacking direction of the organic pattern and the conductor. The conductor has a first straight line segment crossing the boundary, and the first straight line segment has an angle greater than 0 degrees between itself and a first virtual straight line perpendicular to the boundary on the virtual plane.

[0006] Based on the above, in a stretchable panel and vehicle display according to an embodiment of the present invention, a conductor is provided on the organic pattern connecting the two island elements, and the conductor has a straight line segment at the boundary between the organic pattern and the inorganic pattern of each of the two island elements. Since the extension direction of the straight line segment of the conductor crossing the boundary deviates from the virtual straight line perpendicular to the boundary, the strain generated when the stretchable panel is stretched will move away from the boundary, thereby ensuring the electrical connection between the conductor and the two island elements.

[0012] FIG1A is a top view of a stretchable panel according to a first embodiment of the present invention. FIG1B is a top view of the stretchable panel of FIG1A when it is stretched. FIG2 is a cross-sectional view of the stretchable panel of FIG1A. FIG3 is a cross-sectional view of another embodiment of the stretchable panel of FIG1A. FIG4 is a cross-sectional view of yet another embodiment of the stretchable panel of FIG1A. FIG2 corresponds to section line A-A' of FIG1A. For clarity, FIG1A and FIG1B only show a portion of the film layer in FIG2.

[0013] Referring to Figures 1A and 2, the stretchable panel 10 includes a plurality of island elements 100, an organic pattern 170, and conductive lines 186. In this embodiment, the plurality of island elements 100 may be disposed on a substrate 110. The material of the substrate 110 may be an organic polymer, such as: elastic rubber material, polyimide (PI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polycarbonate (PC), polyether sulfone (PES), polyarylate, other suitable materials, or combinations of at least two of the aforementioned materials, but is not limited thereto. However, in some embodiments, the stretchable panel may not have a substrate 110.

[0014] For example, a plurality of island elements 100 may be arranged in an array on a substrate 110. For clarity, FIG1A only shows two island elements 100 arranged at intervals along direction X, and does not imply limitation of the invention. In this embodiment, an organic pattern 170 is connected between the plurality of island elements 100. The material of the organic pattern 170 may be various photosensitive materials with a buffering effect. For example, in this embodiment, the Young's modulus of the organic pattern 170 may be less than 10 GPa; the material of the organic pattern 170 may be photosensitive polyimide (PSPI), phenol-formaldehyde resin, epoxy resin, polyisoprene rubber, or other suitable materials; however, the invention is not limited thereto.

[0015] Any two adjacent island elements 100 can be electrically connected to each other via wires 186. For example, wire 186 can be a gate line, common line, power line, or data line electrically connected to the pixel circuit of the island element 100, but the invention is not limited thereto. Wire 186 is disposed on organic pattern 170 and extends between two island elements 100. In this embodiment, wire 186 is made of a metallic material for conductivity considerations. However, the invention is not limited thereto. According to other embodiments, wire 186 can also be made of other conductive materials, such as alloys, nitrides of metallic materials, oxides of metallic materials, oxynitrides of metallic materials, or stacked layers of metallic materials and other conductive materials.

[0016] In detail, the island element 100 has an inorganic pattern 150, and the inorganic pattern 150 has a connected surface 150s and an edge 150e, wherein the surface 150s faces away from the substrate 110. The organic pattern 170 includes a stretchable portion SP and a non-stretchable portion NSP. The stretchable portion SP connects to the edge 150e of the inorganic pattern 150 of the island element 100. The non-stretchable portion NSP extends from the stretchable portion SP and covers the surface 150s of the inorganic pattern 150.

[0017] It should be noted that when the stretchable panel 10 is stretched, the non-stretchable portion NSP of the organic pattern 170 can significantly reduce the strain at the junction of the island element 100 and the conductor 186. In one embodiment, the reduction in strain can reach 50%.

[0018] Further, the edge 150e of the inorganic pattern 150 defines the junction JUNC of the stretchable portion SP of the inorganic pattern 150 and the organic pattern 170 on a virtual plane VP perpendicular to the stacking direction (e.g., direction Z) of the organic pattern 170 and the wire 186, wherein the virtual plane VP is, for example, parallel to the surface 110s of the substrate 110. It is particularly noteworthy that the wire 186 has a first straight line segment 186S1 that crosses the junction JUNC (or the edge 150e of the inorganic pattern 150), and the first straight line segment 186S1 has an angle θ greater than 0 degrees between itself and the first virtual straight line VL1 perpendicular to the junction JUNC on the virtual plane VP (or the surface 110s of the substrate 110).

[0019] First, it should be noted that the design of the included angle θ can further reduce the strain near the junction JUNC of the inorganic pattern 150 and the organic pattern 170 when the stretchable panel 10 is stretched. In one embodiment, compared to a design where the included angle θ is 0 degrees (i.e., the conductor 186 extends through the edge 150e of the inorganic pattern 150 perpendicular to the junction JUNC), an included angle θ greater than 0 degrees can reduce the overall strain near the junction JUNC by up to 60%. Preferably, the included angle θ is greater than 5 degrees and less than 90 degrees.

[0020] In this embodiment, the conductor 186 may also have a second straight segment 186S2. The second straight segment 186S2 extends from the first straight segment 186S1 in a bent manner and is disposed on the stretchable portion SP of the organic pattern 170. When the stretchable panel 10 is not stretched (as shown in FIG1A), the second straight segment 186S2 defines a second virtual straight line VL2 on the surface 110s (or virtual plane VP) of the substrate 110. In this embodiment, the second virtual straight line VL2 may be parallel to the junction JUNC crossed by the conductor 186, but is not limited thereto.

[0021] It is particularly noteworthy that when the stretchable panel 10 is stretched along the arrangement direction (e.g., direction X) of the two island elements 100 (as shown in FIG1B), the deflection direction (e.g., counterclockwise, but not limited thereto) of the second straight segment 186S2 of the conductor 186 relative to the second virtual straight line VL2 on the surface 110s of the substrate 110 is the same as the deflection direction of the first straight segment 186S1 of the conductor 186 relative to the first virtual straight line VL1 on the surface 110s of the substrate 110. For example, in the stretched state of the stretchable panel 10, the angle φ between the second straight segment 186S2 and the second virtual straight line VL2 on the surface 110s of the substrate 110 can be greater than 5 degrees and less than 180 degrees.

[0022] From another perspective, the deflection angle design of the first straight segment 186S1 of the conductor 186 relative to the first virtual straight line VL1 can disperse the strain generated when the stretchable panel 10 is stretched to the bending point of the conductor 186 (e.g., the connection between the first straight segment 186S1 and the second straight segment 186S2), thereby reducing the strain near the connection between the conductor 186 and the island element 100, which helps to ensure the electrical connection between the conductor 186 and the two island elements 100 in the stretched state.

[0023] Referring to Figures 1A and 2, the island element 100 may also have multiple metal layers, such as a first metal layer ML1, a second metal layer ML2, a third metal layer ML3, and a fourth metal layer ML4, but is not limited thereto. In this embodiment, these metal layers may constitute the pixel circuit of the island element 100. For example, the first metal layer ML1 may include a common electrode (not shown), the gate of an active element (not shown), a common line (not shown), a gate line (not shown), or a conductive pattern (not shown) for electrical bridging; the second metal layer ML2 may include a capacitor electrode (not shown) or a conductive pattern for electrical bridging; the third metal layer ML3 may include the source and drain of an active element (not shown), a data line (not shown), or a conductive pattern for electrical bridging; and the fourth metal layer ML4 may include a conductive pattern 200 for electrical bridging, but is not limited thereto.

[0024] On the other hand, the inorganic pattern 150 of the island element 100 may include a buffer layer 120, a gate insulating layer 140, a first interlayer insulating layer 161, and a second interlayer insulating layer 162. The buffer layer 120 is disposed on the side of the first metal layer ML1 opposite to the second metal layer ML2, that is, the buffer layer 120 is located between the first metal layer ML1 and the substrate 110. The gate insulating layer 140 is disposed between the first metal layer ML1 and the buffer layer 120. The first interlayer insulating layer 161 is disposed between the first metal layer ML1 and the second metal layer ML2. The second interlayer insulating layer 162 is disposed between the second metal layer ML2 and the third metal layer ML3.

[0025] In this embodiment, the second interlayer insulating layer 162 may define the surface 150s of the inorganic pattern 150. That is, the second interlayer insulating layer 162 covers the portion of the non-stretchable portion NSP of the organic pattern 170. The conductor 186 may be electrically connected to the second metal layer ML2 via the second interlayer insulating layer 162 and the contact hole TH of the non-stretchable portion NSP of the organic pattern 170, but is not limited thereto.

[0026] It is particularly noteworthy that, in this embodiment, the buffer layer 120, the gate insulating layer 140, the first interlayer insulating layer 161, and the second interlayer insulating layer 162 each have side surfaces 120ss, 140ss, 161ss, and 162ss facing the stretchable portion SP, and these side surfaces are aligned with each other to form the edge 150e of the inorganic pattern 150. The edge 150e of the inorganic pattern 150 defines the boundary JUNC between the inorganic pattern 150 and the stretchable portion SP of the organic pattern 170 on the surface 110s (or virtual plane VP) of the substrate 110.

[0027] However, the present invention is not limited thereto. Referring to FIG3, in another embodiment of the stretchable panel 10A, the edge 150e-A of the inorganic pattern 150A of the island element 100A can be defined by the side 120ss of the buffer layer 120, while the non-stretchable portion NSP of the organic pattern 170 can directly cover the side 140ss' of the gate insulating layer 140A, the side 161ss' of the first interlayer insulating layer 161A, and the side 162ss' of the second interlayer insulating layer 162A. That is, in this embodiment, the boundaries of the gate insulating layer 140A, the first interlayer insulating layer 161A, and the second interlayer insulating layer 162A can be recessed relative to the boundary of the buffer layer 120.

[0028] Referring to FIG4, in another embodiment of the stretchable panel 10B, the edge 150e-B of the inorganic pattern 150B of the island element 100B can be defined by the side 140ss of the gate insulating layer 140 and the side 161ss of the first interlayer insulating layer 161. The gate insulating layer 140 can directly cover the side 120ss' of the buffer layer 120A, while the non-stretchable portion NSP of the organic pattern 170 can directly cover the side 162ss' of the second interlayer insulating layer 162A.

[0029] Referring to Figures 1A and 2, in this embodiment, the stretchable panel 10 may further include an insulating layer 190 covering the conductor 186 and the island element 100. The insulating layer 190 may also serve as a protective layer. In this embodiment, the material of the insulating layer 190 may be an inorganic material (e.g., silicon oxide, silicon nitride, silicon oxynitride, or a stack of at least two of the above materials), an organic material, or a combination thereof. In this embodiment, the insulating layer 190 may be provided with a conductive pattern 200 of a fourth metal layer ML4, wherein the conductive pattern 200 may penetrate the insulating layer 190 to electrically connect the conductor 186.

[0030] In this embodiment, each island element 100 may also be provided with a planarization layer 210, a transparent conductive layer 220, and multiple light-emitting elements 230 of different emitting colors. The planarization layer 210 covers the fourth metal layer ML4. The transparent conductive layer 220 is disposed on the planarization layer 210 and electrically connected to the conductive pattern 200 of the fourth metal layer ML4, but is not limited thereto. For example, multiple light-emitting elements 230 may be electrically bonded to the transparent conductive layer 220 and are respectively suitable for emitting red light, green light, and blue light, but are not limited thereto. More specifically, in this embodiment, multiple light-emitting elements 230 may be electrically connected to the pixel circuit of the island element 100 via the transparent conductive layer 220 and the conductive pattern 200, but the present invention is not limited thereto.

[0031] FIG5 is a schematic diagram of an in-vehicle display according to an embodiment of the present invention. FIG6A is a cross-sectional schematic diagram of the in-vehicle display of FIG5 when it is partially recessed. FIG6B is a cross-sectional schematic diagram of the in-vehicle display of FIG5 when it is partially convex. FIG6A and FIG6B correspond to section line B-B' of FIG5.

[0032] Referring to Figures 1A, 2, and 5, the aforementioned stretchable panel 10 can be applied to the vehicle display 5. For example, in this embodiment, the vehicle display 5 can serve as the display / operation interface of the vehicle central control platform 1, but is not limited thereto. In other embodiments, the stretchable panel 10 can also be applied to other devices that require a human-machine interface.

[0033] In detail, the vehicle-mounted display 5 may include a stretchable panel 10 and a plurality of telescopic mechanisms 50. The stretchable panel 10 may be a display panel, a touch panel, or a combination thereof. The stretchable panel 10 has an operating surface 10s, and the telescopic mechanisms 50 are disposed on the side of the stretchable panel 10 opposite to the operating surface 10s. In this embodiment, the plurality of telescopic mechanisms 50 may be arranged at intervals along directions X and Y, wherein directions X and Y intersect each other and are perpendicular to direction Z. More specifically, the telescopic mechanisms 50 are arranged in a honeycomb pattern in the normal direction (e.g., direction Z) of the operating surface 10s of the stretchable panel 10. However, the invention is not limited thereto. In other embodiments, the arrangement of these telescopic mechanisms 50 may be adjusted according to the actual application of the display device.

[0034] The telescopic mechanism 50 is adapted to deform the stretchable panel 10 along a direction intersecting the operating surface 10s (e.g., direction Z). More specifically, the telescopic mechanism 50 is used to cause a portion of the stretchable panel 10 to be recessed toward the side opposite to the operating surface 10s (as shown in FIG. 6A), or to cause a portion of the stretchable panel 10 to be protruded toward the side of the operating surface 10s (as shown in FIG. 6B). The aforementioned portion of the stretchable panel 10 is, for example, the part of the stretchable panel 10 connected to each telescopic mechanism 50. When a portion of the stretchable panel 10 is deformed by the telescopic mechanism 50, the spacing between the plurality of island elements 100 thereon increases because the substrate 110 is stretched (as shown in FIG. 1B).

[0035] Another embodiment will be listed below to illustrate this disclosure in detail, wherein the same components will be marked with the same symbols, and the description of the same technical content will be omitted. For the omitted parts, please refer to the foregoing embodiments, and they will not be repeated below.

[0036] FIG7A is a top view of a stretchable panel according to a second embodiment of the present invention. FIG7B is a top view of the stretchable panel of FIG7A when it is stretched. Referring to FIG7A, the difference between the stretchable panel 11 of this embodiment and the stretchable panel 10 of FIG1A is that the wire configuration connecting the two island-shaped elements is different.

[0037] Specifically, in the stretchable panel 11 of this embodiment, the connection points between the two island elements 100 and the conductor 186A are not located between the two island elements 100. More specifically, in this embodiment, the orthographic projection of the conductor 186A on the surface 110s of the substrate 110 presents a serpentine shape. In this embodiment, when the stretchable panel 11 is not stretched, the second virtual straight line VL2 defined by the second straight line segment 186S2 of its conductor 186A on the surface 110s of the substrate 110 is perpendicular to the junction JUNC (or the edge 150e of the inorganic pattern 150) crossed by the conductor 186A.

[0038] Since the angle θ between the first straight segment 186S1 of the conductor 186A in this embodiment and the first virtual straight line VL1 perpendicular to the junction JUNC on the surface 110s of the substrate 110 and the resulting technical effect are similar to those of the stretchable panel 10 in FIG1A, detailed descriptions can be found in the relevant paragraphs of the foregoing embodiments, and will not be repeated here.

[0039] In summary, in a stretchable panel and vehicle display according to an embodiment of the present invention, a conductor is provided on the organic pattern connecting the two island elements, and the conductor has a straight line segment at the boundary between the organic pattern and the inorganic pattern of each of the two island elements. Since the extension direction of the straight line segment of the conductor crossing the boundary deviates from the virtual straight line perpendicular to the boundary, the strain generated when the stretchable panel is stretched will move away from the boundary, thereby ensuring the electrical connection between the conductor and the two island elements.
