[0070] Figure 1 This is an exploded view of an electronic device according to an embodiment of the present disclosure. Figure 2 for Figure 1 A cross-sectional schematic diagram of an electronic device. Figure 3 for Figure 2 A top view of a switchable panel in an electronic device. Figure 4 for Figure 3 An enlarged schematic diagram of area R1 of the switchable panel. Figure 5A for Figure 4 A schematic diagram of the cross section of region R1 along section line I-I'. Figure 5A for Figure 4 A schematic diagram of the cross section of region R1 along section line II-II'. Figure 6 for Figure 3 An enlarged schematic diagram of area R2 of the switchable panel. For clarity and ease of explanation, the diagram is shown below. Figure 3 Several components of the switchable panel 300 in the electronic device 10 (e.g., insulating layer IL1, insulating layer IL2, insulating layer IL3, second substrate 350, and dielectric layer 360) are omitted from the diagram.

[0071] Please refer to Figure 1 , Figure 2 as well as Figure 3 The electronic device 10 disclosed herein includes a backlight module 100, an optical module 200, a switchable panel 300, and a display panel 400. For example... Figure 3 As shown, the electronic device 10 has a first region A1 and a second region A2 adjacent to the first region A1. In this embodiment, the second region A2 may surround the first region A1, but is not limited thereto.

[0072] An optical module 200 is disposed on the backlight module 100. The optical module 200 may include at least one prism layer, but is not limited thereto. In some embodiments, an optical module may be omitted as required by design.

[0073] A switchable panel 300 is disposed on the optical module 200 and between the backlight module 100 and the display panel 400. The switchable panel 300 includes a first substrate 310, an insulating layer IL1, an electrode layer 320, a first conductive portion 330, a second conductive portion 340, a first contact hole C1, a second contact hole C2, a third contact hole C3, a fourth contact hole C4, an insulating layer IL2, an insulating layer IL3, a second substrate 350, and a dielectric layer 360.

[0074] The first substrate 310 has a first surface 311 and a second surface 312 facing each other. The first surface 311 faces the display panel 400, and the second surface 312 faces the backlight module 100. Figure 3 As shown, the second region A2 can be closer to the edge E1 of the first substrate 310 than the first region A1.

[0075] The first conductive portion 330 and the second conductive portion 340 are respectively disposed on the first surface 311 of the first substrate 310. For example... Figure 3 As shown, a first conductive portion 330 and a second conductive portion 340 are disposed within the second region A2. The first conductive portion 330 and the second conductive portion 340 can be physically separated from each other. In some embodiments, the first conductive portion 330 and the second conductive portion 340 can be electrically separated from each other, and the first conductive portion 330 and the second conductive portion 340 transmit different signals. In this embodiment, the first conductive portion 330 and the second conductive portion 340 are opaque, and the first conductive portion 330 and the second conductive portion 340 may comprise metal or metal oxide, such as copper or other opaque conductive materials, but are not limited thereto.

[0076] An insulating layer IL1 is disposed on the first conductor portion 330 and the second conductor portion 340. The insulating layer IL1 can cover the first conductor portion 330 and the second conductor portion 340.

[0077] An electrode layer 320 is disposed on the first surface 311 of the first substrate 310 and the insulating layer IL1. The electrode layer 320 is disposed between the conductive portion (i.e., the first conductive portion 330 and the second conductive portion 340) and the dielectric layer 360. In this embodiment, the electrode layer 320 is transparent, and the electrode layer 320 may include indium tin oxide (ITO) or other transparent conductive materials, but is not limited thereto.

[0078] The electrode layer 320 includes a first electrode portion 321 and a second electrode portion 322. For example... Figure 3 As shown, at least a portion of the first electrode portion 321 and at least a portion of the second electrode portion 322 may be disposed within the first region A1. The first electrode portion 321 and the second electrode portion 322 may be physically separated from each other. In some embodiments, the first electrode portion 321 and the second electrode portion 322 may be electrically separated from each other, and the first electrode portion 321 and the second electrode portion 322 transmit different signals. In this embodiment, the first electrode portion 321 may be electrically connected to the first wire portion 330, and the second electrode portion 322 may be electrically connected to the second wire portion 340, so as to reduce the problem of impedance or uneven potential distribution of the first electrode portion 321 and the second electrode portion 322 in the first region A1.

[0079] In detail, such as Figure 3As shown, the first electrode portion 321 may include a first branch 3211 and a second branch 3212 extending along the first direction X. The second electrode portion 322 may include a third branch 3221 and a fourth branch 3222 extending along the first direction X. In this embodiment, a first voltage (or a first signal) may be applied to the first electrode portion 321, and a second voltage (or a second signal) may be applied to the second electrode portion 322, and the first voltage may be different from the second voltage (or the first signal may be different from the second signal).

[0080] In this embodiment, the first direction X, the second direction Y, and the third direction Z are different directions. The first direction X and the second direction Y are the extension directions of the first substrate 310, and the first direction X is, for example, the extension direction Z. Figure 3 The vertical direction, the second direction Y is, for example, Figure 3 The horizontal direction, and the third direction Z, for example, is the normal direction of the first substrate 310. The first direction X may be substantially perpendicular to the second direction Y, and the first direction X and the second direction Y may each be substantially perpendicular to the third direction Z, but are not limited thereto.

[0081] Please refer to Figure 4 , Figure 5A , Figure 5B as well as Figure 6 The first contact hole C1, the second contact hole C2, the third contact hole C3, and the fourth contact hole C4 can penetrate the insulating layer IL1. The opposite sides of the first contact hole C1 can respectively contact the first branch 3211 of the first electrode portion 321 and the first wire portion 330. The opposite sides of the second contact hole C2 can respectively contact the second branch 3212 of the first electrode portion 321 and the first wire portion 330. The opposite sides of the third contact hole C3 can respectively contact the third branch 3221 of the second electrode portion 322 and the second wire portion 340. The opposite sides of the fourth contact hole C4 can respectively contact the fourth branch 3222 of the second electrode portion 322 and the second wire portion 340. That is, the first branch 3211 can be electrically connected to the first wire portion 330 via the first contact hole C1, the second branch 3212 can be electrically connected to the first wire portion 330 via the second contact hole C2, the third branch 3221 can be electrically connected to the second wire portion 340 via the third contact hole C3, and the fourth branch 3222 can be electrically connected to the second wire portion 340 via the fourth contact hole C4. Furthermore, as... Figure 4 and Figure 6 As shown, the shapes of the first contact hole C1, the second contact hole C2, the third contact hole C3, and the fourth contact hole C4 can be circular, but are not limited thereto. In some embodiments, the shapes of the first contact hole C1, the second contact hole C2, the third contact hole C3, and the fourth contact hole C4 can be rectangular (not shown).

[0082] Please refer to Figure 4 and Figure 6 The first contact hole C1 can be offset from the second contact hole C2 in the second direction Y, and the first contact hole C1 does not overlap with the second contact hole C2 in the second direction Y. This reduces the risk of short circuits between adjacent first branches 3211 and third branches 3221 (or between second branches 3212 and third branches 3221) due to excessive proximity. The third contact hole C3 can at least partially overlap with the fourth contact hole C4 in the second direction Y. Furthermore, in the first direction X, neither the first contact hole C1 nor the second contact hole C2 overlaps with the third contact hole C3 or the fourth contact hole C4.

[0083] Please refer to Figure 4 and Figure 6 The first branch 3211 may include a connected first portion P1 and a second portion P2; wherein the first portion P1 does not overlap with the first conductor portion 330 in the third direction Z, and the second portion P2 may overlap with the first conductor portion 330 in the third direction Z. The second branch 3212 may include a connected third portion P3 and a fourth portion P4; wherein the third portion P3 does not overlap with the first conductor portion 330 in the third direction Z, and the fourth portion P4 may overlap with the first conductor portion 330 in the third direction Z. The third branch 3221 may include a connected fifth portion P5, a sixth portion P6, and a seventh portion P7, wherein the sixth portion P6 is disposed between the fifth portion P5 and the seventh portion P7; wherein the fifth portion P5 does not overlap with the first conductor portion 330 in the third direction Z, and the sixth portion P6 and the seventh portion P7 may overlap the first conductor portion 330 in the third direction Z.

[0084] Please refer to Figure 4 and Figure 6 In the second direction Y, the sixth portion P6 may overlap the first contact hole C1, and the seventh portion P7 may overlap the second contact hole C2. Furthermore, in the second direction Y, the sixth portion P6 may be curved towards the direction of the fourth portion P4, and the seventh portion P7 may be curved towards the direction of the second portion P2, with the bending direction of the sixth portion P6 being approximately opposite to that of the seventh portion P7. This reduces the risk of short circuits occurring between adjacent first branches 3211 and third branches 3221 (or between second branches 3212 and third branches 3221) due to excessive proximity. In other words, the portion of the third branch 3221 that does not overlap the first conductor portion 330 (i.e., the fifth portion P5) may have a straight shape, and the portion of the third branch 3221 that overlaps the first conductor portion 330 (i.e., the sixth portion P6 and the seventh portion P7) may have a curved shape. Furthermore, the portion of the fourth branch 3222 that does not overlap with the first conductor portion 330 may also have a straight shape, and the other portion of the fourth branch 3222 that overlaps with the first conductor portion 330 may also have a curved shape.

[0085] Please refer to Figure 4 and Figure 6 In the second direction Y, the first part P1 and the third part P3 have a maximum width W1, and the second part P2 and the fourth part P4 have a maximum width W2. In this embodiment, the maximum width W1 can be less than the maximum width W2, and both the maximum width W1 and the maximum width W2 can be less than 10 micrometers (μm) and greater than 1 micrometer (i.e., 1μm ≤ W1 ≤ W2 ≤ 10μm), but are not limited thereto.

[0086] Please refer to Figure 4 and Figure 6 In the second direction Y, the fifth portion P5 has a width W3, and the sixth portion P6 and the seventh portion P7 have a width W4. In this embodiment, the width W3 is approximately equal to the width W4, and the widths W3 and W4 can be less than 10 micrometers and greater than 1 micrometer (i.e., W3 = W4, 1 μm ≤ W3(W4) ≤ 10 μm), but are not limited thereto.

[0087] Please refer to Figure 4 and Figure 6 In the second direction Y, the minimum distance D1 exists between the first part P1 and the fifth part P5 (or between the third part P3 and the fifth part P5), the minimum distance D2 exists between the second part P2 and the sixth part P6 (or between the fourth part P4 and the sixth part P6), and the minimum distance D2 exists between the second part P2 and the seventh part P7 (or between the fourth part P4 and the seventh part P7). In this embodiment, the minimum distance D2 can be less than the minimum distance D1, and both the minimum distance D1 and the minimum distance D2 can be less than 5 micrometers and greater than 1 micrometer (i.e., 1μm ≤ D2 ≤ D1 ≤ 10μm). This can reduce the spacing between adjacent first branches 3211 and third branches 3221 (or between second branches 3212 and third branches 3221), and can reduce the risk of short circuits due to their close proximity, but is not limited to this.

[0088] For example, in this embodiment, the maximum width W1 may be 4 micrometers, the maximum width W2 may be 8 micrometers, the width W3 may be 4 micrometers, the width W4 may be 4 micrometers, the minimum distance D1 may be 4 micrometers, and the minimum distance D2 may be 3 micrometers, but is not limited thereto.

[0089] Please refer to Figure 1 and Figure 2 An insulating layer IL2 is disposed on the electrode layer 320, and the insulating layer IL2 can cover the electrode layer 320.

[0090] A dielectric layer 360 is disposed on the insulating layer IL2, and the dielectric layer 360 is disposed between the electrode layer 320 and the second substrate 350. In this embodiment, the dielectric layer 360 can be liquid crystal, but is not limited thereto.

[0091] An insulating layer IL3 is disposed on the dielectric layer 360, and the insulating layer IL3 is disposed between the dielectric layer 360 and the second substrate 350.

[0092] The second substrate 350 is disposed on the insulating layer IL2, and the second substrate 350 may be disposed opposite to the first surface 311 of the first substrate 310.

[0093] Display panel 400 is disposed on switchable panel 300. Display panel 400 may at least partially overlap switchable panel 300 in the third direction Z. Display panel 400 may include insulating layer 410, substrate 420, dielectric layer 430, color filter layer 440, substrate 450, and insulating layer 460. Substrate 420 is disposed on insulating layer 410, dielectric layer 430 is disposed on substrate 420, color filter layer 440 is disposed on dielectric layer 430, substrate 450 is disposed on color filter layer 440, and insulating layer 460 is disposed on substrate 450. Dielectric layer 430 is disposed between substrate 420 and substrate 450, and color filter layer 440 is disposed between dielectric layer 430 and substrate 450. In this embodiment, dielectric layer 430 may be liquid crystal, but is not limited thereto. The color filter layer 440 may include, but is not limited to, a red filter layer 441, a green filter layer 442, and a blue filter layer 443.

[0094] In this embodiment, the arrangement of the dielectric layer 360 in the switchable panel 300 can be changed by applying voltage or not applying voltage, thereby changing the direction of light from the backlight module 10 when passing through the switchable panel 300, so that the screen displayed by the electronic device 10 can have the effect of privacy protection or sharing.

[0095] In this embodiment, the materials of the first substrate 310, the second substrate 350, the substrate 420, and the substrate 450 may include glass, quartz, sapphire, ceramic, polycarbonate (PC), polyimide (PI), polyethylene terephthalate (PET), other suitable materials, or combinations thereof, but are not limited thereto.

[0096] In this embodiment, insulating layers IL1, IL2, IL3, 410, and 460 may be single-layer or multi-layer structures, and may include organic materials, inorganic materials, or combinations thereof, but are not limited thereto.

[0097] Other embodiments will be listed below for illustration. It must be noted that the following embodiments use the component reference numerals and some content from the foregoing embodiments, with the same reference numerals representing the same or similar components, and descriptions of identical technical content omitted. For explanations of the omitted parts, please refer to the foregoing embodiments; these will not be repeated in the following embodiments.

[0098] Figure 7 for Figure 3 An enlarged schematic diagram of region R1 of a switchable panel in an electronic device according to another embodiment. Please also refer to... Figure 7 as well as Figure 4 The electronic device 10a in this embodiment is similar to Figure 4 The electronic device 10 differs from the other in that, in the switchable panel 300a of the electronic device 10a in this embodiment, the sixth part P6 and the seventh part P7 of the third branch 3221a are not bent and do not have a curved shape, and the fourth branch 3222a overlapping the other part of the first conductor portion 330 also does not have a curved shape.

[0099] Specifically, please refer to Figure 7 The first contact hole C1 can be aligned with the second contact hole C2 in the second direction Y, and the first contact hole C1 can partially overlap the second contact hole C2 in the second direction Y.

[0100] In the second direction Y, the sixth part P6 may overlap the first contact hole C1 and the second contact hole C2, and the seventh part P7 may overlap the first contact hole C1 and the second contact hole C2.

[0101] In this embodiment, the width W4 of the sixth portion P6 and the seventh portion P7 can be smaller than the width W3 of the fifth portion P5, and the widths W3 and W4 can be less than 10 micrometers and greater than 1 micrometer (i.e., 1 μm ≤ W4 ≤ W3 ≤ 10 μm). This can reduce the risk of short circuits occurring between adjacent first branches 3211 and third branches 3221a (or between second branches 3212 and third branches 3221a) due to being too close, but is not limited to this. That is, the third branch 3221a includes a portion that does not overlap with the first conductor portion 330 (i.e., the fifth portion P5) and another portion that overlaps with the first conductor portion 330 (i.e., the sixth portion P6 and the seventh portion P7), and the width W4 of the other portion is smaller than the width W3 of the portion.

[0102] In this embodiment, the minimum distance D2 between the second part P2 and the sixth part P6 (or between the fourth part P4 and the sixth part P6) can be less than the minimum distance D1 between the first part P1 and the fifth part P5 (or between the third part P3 and the fifth part P5), and both the minimum distance D1 and the minimum distance D2 can be less than 5 micrometers and greater than 1 micrometer (i.e., 1μm ≤ D2 ≤ D1 ≤ 10μm), so as to reduce the spacing between adjacent first branches 3211 and third branches 3221a (or between second branches 3212 and third branches 3221a) and reduce the risk of short circuit due to the two being too close, but it is not limited to this.

[0103] For example, in this embodiment, the maximum width W1 may be 4 micrometers, the maximum width W2 may be 8 micrometers, the width W3 may be 4 micrometers, the width W4 may be 2 micrometers, the minimum distance D1 may be 4 micrometers, and the minimum distance D2 may be 3 micrometers, but is not limited thereto.

Figure 9 for Figure 8 A cross-sectional schematic diagram of an electronic device. For clarity and ease of explanation, the accompanying drawings are provided. Figure 8 and Figure 9 Omitted Figure 1 and Figure 2 Several components in the electronic device 10 (e.g., backlight module, optical module, dielectric layer, and display panel, etc.). Please also refer to... Figure 1 , Figure 2 , Figure 8 as well as Figure 9 The electronic device 10b in this embodiment is similar to Figure 1 and Figure 2 The electronic device 10 differs from the other in that: in the electronic device 10b of this embodiment, the switchable panel 300b further includes a third conductor portion 370, a fifth contact hole C5, another electrode layer 380 and a connector 390, and the electrode layer 320b further includes a third electrode portion 323.

[0105] Specifically, please refer to Figure 8 and Figure 9The third conductive portion 370 is disposed on the first surface 311 of the first substrate 310 and covered by the insulating layer IL1. The first conductive portion 330, the second conductive portion 340, and the third conductive portion 370 can be physically separated from each other. In some embodiments, the first conductive portion 330, the second conductive portion 340, and the third conductive portion 370 can be electrically separated from each other, and the first conductive portion 330, the second conductive portion 340, and the third conductive portion 370 transmit different signals. In this embodiment, the third conductive portion 370 is opaque, and the third conductive portion 370 may include metal or metal oxide, such as copper or other opaque conductive materials, but is not limited thereto.

[0106] The third electrode portion 323 is disposed on the first surface 311 of the first substrate 310 and on the insulating layer IL1. The third electrode portion 323 is disposed within the second region A2. The first electrode portion 321, the second electrode portion 322, and the third electrode portion 323 can be physically separated from each other. In some embodiments, the first electrode portion 321, the second electrode portion 322, and the third electrode portion 323 can be electrically separated from each other, and the first electrode portion 321, the second electrode portion 322, and the third electrode portion 323 transmit different signals. In some embodiments, the third electrode portion 323 has the same shape as the third wire portion 370, but this is not a limitation.

[0107] The fifth contact hole C5 can penetrate the insulating layer IL1. The opposite sides of the fifth contact hole C5 can respectively contact the third electrode part 323 and the third wire part 370. That is to say, the third electrode part 323 can be electrically connected to the third wire part 370 through the fifth contact hole C5.

[0108] Another electrode layer 380 is disposed on the insulating layer IL3, and the other electrode layer 380 is disposed between the dielectric layer 360 and the second substrate 350.

[0109] A connector 390 is disposed on the first surface 311 of the first substrate 310, and is located between the third electrode portion 323 and the other electrode layer 380. The opposite sides of the connector 390 can respectively contact the other electrode layer 380 and the third electrode portion 323. That is, the other electrode layer 380 can be electrically connected to the third electrode portion 323 via the connector 390. In this embodiment, the connector 390 can be a gold ball, but is not limited thereto.

[0110] In summary, in the electronic device of this embodiment, by providing conductive wire portions (i.e., first conductive wire portions and second conductive wire portions) electrically connected to electrode portions (i.e., first electrode portions and second electrode portions) within the second region, the impedance of the electrode portions in the first region can be reduced. By misaligning the first contact hole with the second contact hole in the second direction, by having the third branch overlap the other portion of the first conductive wire portion (i.e., the sixth portion and the seventh portion) in a curved shape, or by making the width of the third branch overlapping the other portion of the first conductive wire portion smaller than the width of the portion of the third branch not overlapping the first conductive wire portion, the risk of short circuits occurring between adjacent first and third branches (or between second and third branches) due to excessive proximity can be reduced.
