These seven cross-sectional schematic diagrams schematically illustrate the protrusion structure in the peripheral area of the electronic device and the details of the internal protrusion structure. FIG. 2A to FIG. 8A They are Figures 2 to 8 Magnified view of the protrusion structure in the middle. Figures 2B to 8B They are Figures 2 to 8 Magnified view of the internal protrusion structure.
[0021] Please refer to Figure 2 , Figure 2A and Figure 2B The electronic device 1A includes a substrate 10, a first metal layer 11 disposed on the substrate 10, and a protrusion structure 12 disposed on the substrate 10 and located in the peripheral region R2.
[0022] The substrate 10 may carry the first metal layer 11 and the protrusion structure 12. In some embodiments, the substrate 10 may include a hard substrate or a flexible substrate. In some embodiments, the substrate 10 may include a light-transmitting substrate or a non-light-transmitting substrate. In some embodiments, the substrate 10 may be a single-layer substrate or a composite substrate.
[0023] In this embodiment, the substrate 10 includes, for example, a first substrate 100, a second substrate 102, and an intermediate layer 104. The second substrate 102 is located between the first metal layer 11 and the first substrate 100, and the intermediate layer 104 is located between the first substrate 100 and the second substrate 102. The materials of the first substrate 100 and the second substrate 102 include, for example, a flexible material such as polyimide (PI). The material of the intermediate layer 104 includes, for example, silicon oxide or nitride. In some embodiments, the thickness T100 of the first substrate 100 may be between 3 μm and 15 μm (3 μm≦T100≦15 μm), the thickness T102 of the second substrate 102 may be between 3 μm and 11 μm (3 μm≦T102≦11 μm), and the thickness T104 of the intermediate layer 104 may be between 0.3 μm and 2 μm (0.3 μm≦T104≦2 μm), but not limited thereto. In the present embodiment, the thickness T100 of the first substrate 100, the thickness T102 of the second substrate 102, and the thickness T104 of the intermediate layer 104 are, for example, 5.5 μm, 5.1 μm, and 0.6 μm, respectively. In this article, the thickness of the film layer refers to the maximum thickness of the film layer in the normal direction (or thickness direction) DT1 of the substrate 10. However, the number, type, stacking order, material or thickness of the film layers of the substrate 10 may be changed as required and are not limited to the above. In some embodiments, the thickness T102 of the second substrate 102 may be less than or equal to the thickness T100 of the first substrate 100 .
[0024] The first metal layer 11 is suitable for signal transmission. Taking the organic light emitting diode display device as an example, the first metal layer 11 can be a patterned metal layer. For example, the first metal layer 11 may include a patterned metal layer located in the display area R1 (see Figure 1 ) in the plurality of lower electrodes (not shown) of the plurality of organic light emitting diodes E, but not limited thereto. The first metal layer 11 may be a single metal layer or a metal stack layer. In some embodiments, the thickness of the first metal layer 11 may be between 50nm and 150nm (50nm≦thickness of the first metal layer 11≦150nm), or between 70nm and 110nm (70nm≦thickness of the first metal layer 11≦110nm), but not limited thereto. In the present embodiment, the first metal layer 11 includes, for example, three conductive layers. The three conductive layers are sequentially formed on the substrate 10 along the normal direction DT1 of the substrate 10. The materials of the three conductive layers are, for example, molybdenum, aluminum, molybdenum or titanium, aluminum, and titanium, in sequence. In addition, the thicknesses of the three conductive layers are, for example, 3.5nm, 77.2nm, and 5.8nm, in sequence. In some embodiments, the thicknesses of the three conductive layers of the first metal layer 11 are respectively the maximum thicknesses in the normal direction DT1, and a relatively flat portion may be selected for measurement. However, the number, type, stacking sequence, material or thickness of the first metal layer 11 can be changed according to needs and is not limited to the above.
[0025] The first metal layer 11 extends into the protrusion structure 12 and ends in the protrusion structure 12. Figure 2 As shown, the first metal layer 11 extends into the protrusion structure 12, for example, from the interior of the substrate 10 (for example, the display area R1) toward the edge of the substrate 10 (for example, the peripheral area R2), and the side of the first metal layer 11 close to the edge of the substrate 10 is located in the protrusion structure 12 and may have a distance from the outer edge S12P of the protrusion structure 12.
[0026] The protrusion structure 12 may include at least one organic insulating layer. In the embodiments disclosed herein, the protrusion structure 12 may provide appropriate protection for the first metal layer 11, reduce the probability of the first metal layer 11 being corroded, and enable the electronic device 1A to have good display quality or electrical performance. If the first metal layer 11 extending into the protrusion structure 12 is too close to the outer edge S12P of the protrusion structure 12, the probability of the first metal layer 11 being corroded may increase. On the contrary, if the first metal layer 11 extending into the protrusion structure 12 is too close to the inner edge S12N of the protrusion structure 12, insufficient protection may result due to alignment errors. In some embodiments (see Figure 2A ), the width W1 of the protrusion structure 12, and the distance G1 between the first metal layer 11 and the outer edge S12P of the protrusion structure 12 may satisfy the relationship of 0.1≦G1 / W1≦0.9, so as to enhance the protection of the first metal layer 11 by the protrusion structure 12. In some embodiments, in any cross section of the protrusion structure 12 in the normal direction DT1 of the substrate 10, the width W1 is defined as the maximum width of the protrusion structure 12 in the direction DT2, and the distance G1 is defined as the minimum distance between the first metal layer 11 and the outer edge S12P of the protrusion structure 12 in the direction DT2. The direction DT2 is perpendicular to the normal direction DT1 of the substrate 10.
[0027] According to different requirements, the electronic device 1A may further include other elements or film layers. In this embodiment, the electronic device 1A further includes a first inorganic insulating layer 14, a second inorganic insulating layer 15, an inorganic insulating layer 25, an organic insulating layer 35, a second metal layer 16, and a third metal layer 17. In addition, the protrusion structure 12 includes a first organic insulating layer 120, a second organic insulating layer 122, and a third organic insulating layer 124.
[0028] The first inorganic insulating layer 14, the second metal layer 16, the first organic insulating layer 120, the third metal layer 17, the third organic insulating layer 124, the first metal layer 11, the second organic insulating layer 122 and the second inorganic insulating layer 15 are sequentially disposed on the substrate 10, wherein the first inorganic insulating layer 14 is located between the first organic insulating layer 120 and the substrate 10, the second metal layer 16 is located between the first inorganic insulating layer 14 and the first organic insulating layer 120, the first organic insulating layer 120 is located between the second metal layer 16 and the third metal layer 17, and the third metal layer 11 is located between the first inorganic insulating layer 14 and the first organic insulating layer 120. 17 is located between the first organic insulating layer 120 and the third organic insulating layer 124, the third organic insulating layer 124 is located between the third metal layer 17 and the first metal layer 11, the first metal layer 11 is located between the third organic insulating layer 124 and the second organic insulating layer 122, the second organic insulating layer 122 is located between the first metal layer 11 and the second inorganic insulating layer 15, the second inorganic insulating layer 15 is arranged on the second organic insulating layer 122 and the first inorganic insulating layer 14, and the protrusion structure 12 is located between the second inorganic insulating layer 15 and the first inorganic insulating layer 14.
[0029] The first organic insulating layer 120, the second organic insulating layer 122, and the third organic insulating layer 124 may be made of the same or different materials. For example, the materials of the first organic insulating layer 120, the second organic insulating layer 122, and the third organic insulating layer 124 include acrylic resin or photosensitive resin, but are not limited thereto. In the present embodiment, the first organic insulating layer 120, the second organic insulating layer 122, and the third organic insulating layer 124 are made of the same or similar materials, so there is no obvious interface between the first organic insulating layer 120, the second organic insulating layer 122, and the third organic insulating layer 124. Since water and oxygen may invade along the interfaces between different materials, the first metal layer 11 extending into the protrusion structure 12 is covered by a second organic insulating layer 122 and a third organic insulating layer 124 made of the same or similar materials, and the third metal layer 17 extending into the protrusion structure 12 is covered by a first organic insulating layer 120 and a third organic insulating layer 124 made of the same or similar materials. The probability of the first metal layer 11 and the third metal layer 17 being corroded can be reduced.
[0030] The first inorganic insulating layer 14 and the second inorganic insulating layer 15 can be made of the same or different materials. For example, the materials of the first inorganic insulating layer 14 and the second inorganic insulating layer 15 may include oxides or nitrides, but are not limited thereto. Since the water and oxygen blocking ability of the inorganic insulating layer is better than the water and oxygen blocking ability of the organic insulating layer, the second inorganic insulating layer 15 and the first inorganic insulating layer 14 covering the protruding structure 12 help to improve the water and oxygen blocking effect, thereby reducing the probability of the metal layer (including the first metal layer 11, the second metal layer 16 and the third metal layer 17) being corroded. In some embodiments, the first inorganic insulating layer 14 and the second inorganic insulating layer 15 can be made of the same or similar materials, so that there is no obvious interface between the first inorganic insulating layer 14 and the second inorganic insulating layer 15, thereby reducing the probability of water and oxygen invading the protruding structure 12 from between the first inorganic insulating layer 14 and the second inorganic insulating layer 15 and corroding the metal layer. In some embodiments, at least one of the first inorganic insulating layer 14 and the second inorganic insulating layer 15 may be a stacked layer of multiple inorganic insulating layers.
[0031] The second metal layer 16 may be suitable for signal transmission. Taking the organic light emitting diode display device as an example, the second metal layer 16 may be a patterned metal layer. For example, the second metal layer 16 may include a patterned metal layer located in the display region R1 (see Figure 1 ), multiple data lines (not shown) in the substrate 10, multiple sources and multiple drains of multiple active components (not shown), but not limited to this. The second metal layer 16 may be a single metal layer or a metal stack layer. In some embodiments, the thickness of the second metal layer 16 may be between 350nm and 900nm (350nm≦thickness of the second metal layer 16≦900nm), or between 450nm and 830nm (450nm≦thickness of the first metal layer 11≦830nm), but not limited to this. In the present embodiment, the second metal layer 16 includes, for example, three conductive layers. The three conductive layers are sequentially formed on the substrate 10 along the normal direction DT1 of the substrate 10. The materials of the three conductive layers are, for example, molybdenum, aluminum, molybdenum or titanium, aluminum, and titanium in sequence. In addition, the thicknesses of the three conductive layers are, for example, 102.7nm, 609.4nm, and 54.7nm in sequence. In some embodiments, the thickness of the three conductive layers of the second metal layer 16 is the maximum thickness in the normal direction DT1, and a relatively flat portion can be selected for measurement. However, the number, type, stacking order, material or thickness of the film layers of the second metal layer 16 can be changed according to needs and are not limited to the above. In some embodiments, the thickness T2 of the second metal layer 16 can be greater than the thickness T1 of the first metal layer 11 to reduce impedance or improve the ability of signal transmission.
[0032] The second metal layer 16 extends into the protrusion structure 12 and ends in the protrusion structure 12. Figure 2 and Figure 2AAs shown, the second metal layer 16 extends from the inside of the substrate 10 (e.g., the display area R1) toward the edge of the substrate 10 (e.g., the peripheral area R2) into the protrusion structure 12, and the side of the second metal layer 16 close to the edge of the substrate 10 is located in the protrusion structure 12, wherein the distance between the second metal layer 16 and the outer edge S12P of the protrusion structure 12 is G2. Since the interface between different materials is easily invaded by water and oxygen, and the second metal layer 16 is disposed between the first inorganic insulating layer 14 and the first organic insulating layer 120 made of different materials, compared with the first metal layer 11, the second metal layer 16 can be farther from the outer edge S12P of the protrusion structure 12 (i.e., G2 is greater than G1) to enhance the protection of the second metal layer 16 (water and oxygen blocking effect).
[0033] The third metal layer 17 can be suitable for signal transmission, and the setting of the third metal layer 17 helps to improve the elasticity or flexibility of the circuit design. Taking the organic light emitting diode display device as an example, the third metal layer 17 can be a patterned metal layer. For example, the third metal layer 17 may include circuits for specific functions, such as reference signal lines, power lines or ground lines, but is not limited to this. The third metal layer 17 can be a single metal layer or a metal stack layer. In some embodiments, the thickness of the third metal layer 17 can be between 550nm and 850nm (550nm≦the thickness of the second metal layer 16≦850nm), or between 650nm and 800nm (650nm≦the thickness of the second metal layer 16≦800nm), but is not limited to this. In this embodiment, the third metal layer 17, for example, includes three conductive layers. The three conductive layers are sequentially formed on the substrate 10 along the normal direction DT1 of the substrate 10. The materials of the three conductive layers are, for example, molybdenum, aluminum, molybdenum or titanium, aluminum, and titanium in sequence. In addition, the thicknesses of the three conductive layers are, for example, 68.4 nm, 561.5 nm, and 44.5 nm, respectively. In some embodiments, the thicknesses of the three conductive layers of the third metal layer 17 are respectively the maximum thicknesses in the normal direction DT1, and a relatively flat portion can be selected for measurement. However, the number, type, stacking order, material, or thickness of the film layers of the third metal layer 17 can be changed as required, and are not limited to the above. In some embodiments, the thickness T3 of the third metal layer 17 can be greater than the thickness T1 of the first metal layer 11 to reduce impedance or enhance the ability of signal transmission.
[0034] The third metal layer 17 extends into the protrusion structure 12 and ends in the protrusion structure 12. Figure 2 and Figure 2AAs shown, the third metal layer 17 extends from the inside of the substrate 10 (e.g., the display region R1) toward the edge of the substrate 10 (e.g., the peripheral region R2) into the protrusion structure 12, and a side of the third metal layer 17 close to the edge of the substrate 10 is located in the protrusion structure 12 and maintains a distance G3 from the outer edge S12P of the protrusion structure 12. In this embodiment, G3 is greater than G1, but is not limited thereto.
[0035] The electronic device 1A may further include an internal protrusion structure 18. The internal protrusion structure 18 is disposed on the substrate 10 and is located in the peripheral region R2. The protrusion structure 12 is closer to the edge of the substrate 10 than the internal protrusion structure 18, and a distance G is maintained between the protrusion structure 12 and the internal protrusion structure 18. The internal protrusion structure 18 may include at least one organic insulating layer. In the present embodiment, the internal protrusion structure 18 includes, for example, a second organic insulating layer 122 and a third organic insulating layer 124, but is not limited thereto. The first metal layer 11, the second metal layer 16, and the third metal layer 17 are located between the second inorganic insulating layer 15 and the first inorganic insulating layer 14. Figure 2 As shown, the first metal layer 11 contacts the third metal layer 17 between the protrusion structure 12 and the inner protrusion structure 18, and the third metal layer 17 contacts the second metal layer 16 between the protrusion structure 12 and the inner protrusion structure 18. In the inner protrusion structure 18, the second metal layer 16 and the third metal layer 17 remain in contact, while the first metal layer 11 and the third metal layer 17 are partially separated by the third organic insulating layer 124, and the first metal layer 11 is located between the second organic insulating layer 122 and the third organic insulating layer 124.

[0068] Please refer to Figure 3 , Figure 3A and Figure 3B , the electronic device 1B and Figure 2 , Figure 2A and Figure 2B The main differences between the electronic device 1A in FIG.
[0069] In the electronic device 1B, the thickness T100 of the first substrate 100 , the thickness T102 of the second substrate 102 , and the thickness T104 of the intermediate layer 104 are, for example, 9.6 μm, 5.2 μm, and 0.6 μm, respectively, but not limited thereto.
[0070] The first metal layer 11 is a single-layer metal layer, and the thickness T1 of the first metal layer 11 is 94 nm, but not limited thereto. In some embodiments, the thickness T1 of the first metal layer 11 is the maximum thickness in the normal direction DT1, and a relatively flat portion can be selected for measurement. In the present embodiment, the first metal layer 11 includes a first portion P11 and a second portion P12. The opposite ends of the first portion P11 are respectively located in the protrusion structure 12 and the internal protrusion structure 18. The second portion P12 extends into the internal protrusion structure 18 and terminates in the internal protrusion structure 18, and the second portion P12 is separated from the first portion P11 in the internal protrusion structure 18. In other words, the second portion P12 and the first portion P11 are disconnected (separated) in the internal protrusion structure 18, rather than connected. In this way, when the first metal layer 11 in the protrusion structure 12 is corroded, the corrosion phenomenon can be reduced from spreading through the first metal layer 11 to the display area R1 (see Figure 1 ) occurs.
[0071] The second metal layer 16 includes three conductive layers, and the thickness of the three conductive layers is, for example, 85 nm, 614 nm, and 37 nm in sequence along the normal direction DT1, but is not limited thereto. In some embodiments, the thickness of the three conductive layers of the second metal layer 16 is the maximum thickness in the normal direction DT1, and a relatively flat portion can be selected for measurement. In the present embodiment, the second metal layer 16 includes a first portion P1 extending into the protrusion structure 12 and ending in the protrusion structure 12 and a plurality of second portions P2. The plurality of second portions P2 are separated from the first portion P1 and arranged from the first portion P1 toward the edge of the substrate 10. The second portion P2 of the plurality of second portions P2 that is closest to the edge of the substrate 10 overlaps with the protrusion structure 12 in the normal direction DT1 of the substrate 10. In other words, the second portion P2 that is closest to the edge of the substrate 10 does not extend to the outside of the protrusion structure 12, which can reduce the corrosion of the second metal layer 16.
[0072] The third metal layer 17 includes three conductive layers, and the thicknesses of the three conductive layers along the normal direction DT1 are, for example, 104 nm, 635 nm, and 40 nm, respectively, but not limited thereto. In some embodiments, the thicknesses of the three conductive layers of the third metal layer 17 are the maximum thicknesses along the normal direction DT1, and a relatively flat portion can be selected for measurement.
[0073] The electronic device 1B further includes a fourth metal layer 19. The fourth metal layer 19 is separated from the second metal layer 16 by the first inorganic insulating layer 14. The fourth metal layer 19 may be suitable for signal transmission. Taking the organic light emitting diode display device as an example, the fourth metal layer 19 may be a patterned metal layer, and may include a plurality of patterns 19P. For example, the fourth metal layer 19 may include a plurality of patterns 19P located in the display region R1 (see Figure 1 ), multiple scan lines (not shown) in the peripheral region R2, multiple drains of multiple active components (not shown), and multiple patterns 19P located in the peripheral region R2, but not limited thereto. In some embodiments, the protrusion structure 12 may overlap at least part of the multiple patterns 19P in the normal direction DT1, but not limited thereto. The fourth metal layer 19 may be a single metal layer or a metal stack layer. Please refer to the above description for the metal stack layer, which will not be elaborated here.

However, it should be understood that the values in Table 2 are only Figure 3 However, simple equivalent changes and modifications made according to the specification or claims are still within the scope of the present disclosure.
[0075] In Table 2, WG is the maximum distance between the separation point of the first portion P11 of the first metal layer 11 and the third metal layer 17 and the separation point of the second portion P12 of the first metal layer 11 and the third metal layer 17 in the direction DT2. In this embodiment, the protrusion structure 12 has a step-like descending edge near the outer edge S12P (e.g. Figure 3A ), in other words, the angle between the edge extension line of the protrusion structure 12 and the substrate 10 is substantially different. θ1' is the angle between the second inorganic insulating layer 15 at the step-like descending edge of the protrusion structure 12 and the substrate 10, or can be regarded as the angle between the extension line of the second inorganic insulating layer 15 at the step-like descending edge of the protrusion structure 12 and the substrate 10.

In this embodiment, the protrusion structure 12 has a step-like descending edge (such as Figure 4A As shown), in other words, the protrusion structure 12 can be roughly distinguished by a top and a bottom according to a step-like descending edge. The top can roughly correspond to the second organic insulating layer 122, and the bottom can roughly correspond to the first organic insulating layer 120, but is not limited to this.

[0110] Table 7
[0111] In the embodiments disclosed herein, the protrusion structure includes at least one organic insulating layer and is located in the peripheral area of the electronic device. The first metal layer can extend into the protrusion structure and end in the protrusion structure, which can provide appropriate protection for the first metal layer and reduce the probability of corrosion of the first metal layer, so that the electronic device can have good display quality or electrical performance. In some embodiments, the electronic device can further meet 0.1≦G1 / W1≦0.9 to enhance the protection of the first metal layer by the protrusion structure. In some embodiments, the metal layer extending into the protrusion structure can be coated with multiple organic insulating layers in the protrusion structure to reduce the probability of corrosion of the metal layer. In some embodiments, coating the protrusion structure with multiple inorganic insulating layers helps to enhance the water and oxygen blocking effect, thereby reducing the probability of corrosion of the metal layer extending into the protrusion structure. In some embodiments, the multiple inorganic insulating layers coating the protrusion structure can be made of the same or similar materials, so that there is no obvious interface between the multiple inorganic insulating layers, thereby reducing the probability of water and oxygen invading or corroding the metal layer extending into the protrusion structure from between the multiple inorganic insulating layers. In some embodiments, the second metal layer disposed between the inorganic insulating layer and the organic insulating layer may be further away from the outer edge S12P of the protrusion structure 12 than the first metal layer to enhance the protection of the second metal layer (water and oxygen blocking effect). In some embodiments, the first metal layer may be broken into two parts in the internal protrusion structure to reduce the probability of the corrosion phenomenon spreading to the display area through the first metal layer when the first metal layer in the protrusion structure is corroded.
