[0029] Please refer to Figure 2 and Figure 3 , Figure 2 As shown Figure 1 An enlarged schematic diagram of a first example of a region R1 extending from the middle region R1' along the direction Dy, and Figure 3 The image shows along Figure 2 A schematic diagram of the structural cross-section along line B-B'. Figure 2 and Figure 3 The structure in the electronic device 10 (or display device) may be a part of the structure adjacent to the edge of the substrate 100, but is not limited thereto. Figure 2 and Figure 3 Only a portion of the electronic device 10 is shown as an example. In some embodiments, multiple electronic devices 10 may be interconnected to form a video wall, but this is not a limitation. In other embodiments, the electronic device 10 may not be a video wall display device but may include a single, independent display device, but this is not a limitation. The following will use... Figure 1 The electronic device 10 in the example is used for illustration.
[0030] like Figure 2 and Figure 3 As shown, the electronic device 10 may include a substrate 100, a substrate 102, an adhesive layer 104, multiple conductive lines 106, multiple conductive pads 108, and a wavelength selective layer 110, but is not limited thereto. In some embodiments, the substrate 102 and the adhesive layer 104 may be selectively disposed, but are not limited thereto. The substrate 100 may be disposed opposite to the substrate 102, and the adhesive layer 104 may be disposed between the substrate 100 and the substrate 102. The material of the substrate 100 or the substrate 102 may include glass, quartz, sapphire, polymers (such as polyimide (PI), polyethylene terephthalate (PET)) and / or other suitable materials to serve as a flexible substrate or a rigid substrate, but is not limited thereto. The substrate 100 and the substrate 102 may be made of the same or different materials. The adhesive layer 104 may include, for example, an optically clear resin (OCR), but is not limited thereto.
[0031] The substrate 100 may include a surface 1002 (or a first surface) and a surface 1004 (or a second surface) opposite to the surface 1002, wherein the surface 1002 may be closer to the substrate 102, and the surface 1004 may be farther away from the substrate 102. Furthermore, the substrate 100 may include a side surface 1006, which may be generally parallel to the direction Dz, and may be located between the surface 1002 and the surface 1004, and may connect the surface 1002 and the surface 1004. Figure 2 or Figure 3Taking a conductor 106 as an example, a portion 1060 of the conductor 106 may be disposed on surface 1004, and a portion 1062 of the conductor 106 may be disposed on side surface 1006. The conductor may be, for example, a conductive material connecting the driving element and the conductive pad, or a conductive material connecting the driving element and a circuit layer (not shown) in the display area. In some embodiments, at least a portion of the conductor is not located between substrate 100 and substrate 102; in some embodiments, a portion of the conductor is disposed on side surface 1006 of substrate 100 or on an outer surface (e.g., on surface 1004).
[0032] The conductive wire 106 can be formed on the surface 1004 and side surfaces 1006 of the substrate 100 by a printing process, but is not limited thereto. The conductive wire 106 can be cured and its conductivity improved by an energy beam 114. The material of the conductive wire 106 may include, but is not limited to, conductive adhesive. The conductive adhesive may include glue, colloid, paint, or ink containing conductive components (such as metal or carbon), but is not limited thereto. The conductive metal or carbon may include micron-sized fragments or nanoparticles of a specific type, an unspecified type, or a mixture thereof, but is not limited thereto. The metal may include silver, copper particles, or other metallic materials, but is not limited thereto. The energy beam 114 may irradiate at least a portion of the surface 1004 and / or the side surfaces 1006 of the substrate 100 on which the conductive wire 106 is provided, but is not limited thereto. In some embodiments, the conductive wire 106 may also be formed on the surface 1004 and side surfaces 1006 of the substrate 100 by a vapor deposition or sputtering process, but is not limited thereto. The term "curing" in this case refers to the solidification of liquid materials into a fixed shape after irradiation with an energy beam.
[0033] Furthermore, the energy beam 114 may include, but is not limited to, a laser or a pulsed lamp. For example, the energy beam 114 may include an ultraviolet laser (wavelength less than 400 nm), a visible laser (wavelength from 400 nm to 750 nm), or an infrared laser (wavelength greater than 750 nm), but is not limited to these. The pulsed lamp may, for example, include a pulsed xenon lamp, but is not limited to these. Figure 2 As shown, the energy beam 114 in this embodiment can be applied to the surface 1004 and side 1006 of the substrate 100, but is not limited thereto.
[0034] like Figure 2 and Figure 3 As shown, a conductive pad 108 may be disposed between substrate 100 and substrate 102. In some embodiments, the conductive pad 108 may be disposed on surface 1002 of substrate 100. For example, the conductive pad 108 may be disposed between adhesive layer 104 and substrate 100, but is not limited thereto. In some embodiments, the conductive pad 108 may contact a portion 1062 of wire 106 to achieve electrical connection, but is not limited thereto. Figure 3The conductive pad 108 may have a side surface 1081 that is generally parallel to the direction Dz. In some embodiments, a portion 1062 of the wire 106 may extend from the side surface 1006 of the substrate 100 to the side surface 1081 of the conductive pad 108, such that the portion 1062 of the wire 106 can contact at least a portion of the side surface 1081 of the conductive pad 108 to achieve an electrical connection. In some embodiments, a portion 1062 of the wire 106 may extend from the side surface 1006 of the substrate 100 to the side surface 1081 of the conductive pad 108 and at least a portion of the side surface 1041 of the adhesive layer 104, wherein the side surface 1041 of the adhesive layer 104 is generally parallel to the direction Dz. In some embodiments, a portion 1062 of the conductor 106 may extend from a side surface 1006 of the substrate 100 to a side surface 1081 of the conductive pad 108, a side surface 1041 of the adhesive layer 104, and at least a portion of a side surface 1023 of the substrate 102, wherein the side surface 1023 of the substrate 102 may be substantially parallel to the direction Dz. In some embodiments, the side surface 1006 of the substrate 100, the side surface 1081 of the conductive pad 108, the side surface 1041 of the adhesive layer 104, and the side surface 1023 of the substrate 102 may be aligned with each other, but are not limited thereto.
[0035] For example, the conductive pad 108 can be electrically connected to the light-emitting element in the display area, allowing the wire 106 to be electrically connected to the light-emitting element through the conductive pad 108, but this is not a limitation. In addition, the conductive pad 108 can also be electrically connected to other signal lines or other components in the electronic device 10 according to design requirements.
[0036] In some embodiments, the conductive pad 108 may comprise a metallic conductive material, a transparent conductive material, or a combination thereof. In some embodiments, the aforementioned metallic conductive material may comprise copper (Cu), aluminum (Al), molybdenum (Mo), silver (Ag), tin (Sn), tungsten (W), gold (Au), chromium (Cr), nickel (Ni), platinum (Pt), copper alloys, aluminum alloys, molybdenum alloys, silver alloys, tin alloys, tungsten alloys, gold alloys, chromium alloys, nickel alloys, platinum alloys, other suitable metallic materials, or combinations thereof, but is not limited thereto. In some embodiments, the aforementioned transparent conductive material may comprise a transparent conductive oxide (TCO). For example, transparent conductive oxides may include indium tin oxide (ITO), tin oxide (SnO), zinc oxide (ZnO), indium zinc oxide (IZO), indium gallium zinc oxide (IGZO), indium tin zinc oxide (ITZO), antimony tin oxide (ATO), antimony zinc oxide (AZO), other suitable transparent conductive materials, or combinations thereof, but are not limited thereto.
[0037] Furthermore, for example, wire 106 (e.g., disposed on a portion 1060 of surface 1004) may be electrically connected to an integrated circuit 112. Thus, wire 106 can transmit signals from integrated circuit 112 to components within electronic device 10 via conductive pad 108. Integrated circuit 112 may be disposed on surface 1004 of substrate 100. Integrated circuit 112 may include at least one thin-film transistor for driving components within electronic device 10, but is not limited thereto. In some embodiments, integrated circuit 112 may be disposed directly on substrate 100 or on a flexible circuit board (not shown), but is not limited thereto. In some embodiments, integrated circuit 112 may be electrically connected to wire 106 via a flexible circuit board, but is not limited thereto.
[0038] like Figure 3As shown, a wavelength selectivity layer 110 may be disposed between a conductor 106 (such as a portion 1060 of conductor 106) and a substrate 100 (such as surface 1004 of substrate 100). The wavelength selectivity layer 110 can be used to shield the energy beam 114 to reduce the degradation of components or materials within the electronic device 10 due to the energy beam 114, thereby improving the reliability or display quality of the electronic device 10. For example, the wavelength selectivity layer 110 used in the electronic device 10 can shield the energy beam 114. The shielding effect of the wavelength selectivity layer 110 is defined herein as suppressing the transmittance of the energy beam 114 to less than 10%. In this context, "transmittance" refers to the percentage obtained by dividing the integral value of the spectrum of the energy beam (e.g., a laser) after passing through the wavelength selectivity layer by the integral value of the spectrum before passing through the wavelength selectivity layer.
[0039] For example, the material of wavelength selective layer 110 may include silver, gold, copper, aluminum, chromium, platinum, other suitable metals, alloys or metal oxides described above, or combinations thereof, but is not limited thereto. Furthermore, wavelength selective layer 110 may comprise a single film layer or multiple film layers, but is not limited thereto.
[0040] In some embodiments, the wavelength selectivity layer 110 may be a metallic material layer, which may include silver, gold, copper, aluminum, chromium, platinum, or alloys or metal oxides of the above, or multilayer films containing the above materials, but is not limited thereto. Different types of metals can be used to reflect energy beams 114 in different wavelength ranges. For example, a metallic material layer containing aluminum may have high reflectivity for wavelengths from ultraviolet to infrared, while a metallic material layer containing gold may be suitable for reflecting infrared wavelengths.
[0041] In some embodiments, the wavelength selection layer 110 may employ an infrared absorber, for example, in the infrared band. For instance, the infrared absorber may include, but is not limited to, polycyclic aromatic hydrocarbons, long-chain hydrocarbons containing conjugated double bonds, quantum dots with special core-shell structures or materials, or multilayer films.
[0042] In some embodiments, the wavelength selective layer 110, taking the infrared band as an example, may be a multilayer film. For example, the multilayer film may include a multilayer stacked structure of metal thin films, metal oxide thin films, or complex metal oxide films, but is not limited thereto. The multilayer film may include at least two different refractive indices. By matching the refractive indices of the different film layers, the direction of travel of the energy beam 114 when it enters the film layer can be changed, or it can be totally reflected before entering the film layer, thereby achieving the purpose of shielding the energy beam 114. In addition, the wavelength selective layer described above can also be used to shield energy beams with other wavelength bands.
[0043] In some embodiments, the functions and / or materials of the wavelength selection layer described above can be used independently as needed, or in any combination of two or all three.
[0044] Please refer to Figure 4 and Figure 5 , Figure 4 As shown Figure 1 An enlarged schematic diagram of a second example of region R1 extending from the middle region R1' along the direction Dy, and Figure 5 The image shows along Figure 4 A cross-sectional view of the structure along line C-C' is shown. The difference between the second and first examples is that the conductor 106 may further include a portion 1064, which may be disposed between the substrate 100 and the substrate 102, but is not limited thereto. In some embodiments, the portion 1064 of the conductor 106 may be disposed between the conductive pad 108 and the adhesive layer 104, but is not limited thereto. In some embodiments, the conductive pad 108 may contact the portion 1064 of the conductor 106 to achieve an electrical connection, but is not limited thereto. In other words, a portion 1064 of the wire 106 may extend from between the substrate 100 and the substrate 102 of the electronic device 10 toward the side 1006 of the substrate 100, and a portion 1062 of the wire 106 may continue to extend along the side 1006 toward the surface 1004, and a portion 1060 of the wire 106 may extend on the surface 1004, and an integrated circuit 112 may be disposed on the portion 1060 of the wire 106, but is not limited thereto.
[0045] Please refer to Figure 6 As shown Figure 1 A schematic diagram of a cross section A-A' in the central region R2. Figure 6 The structure in can be, for example, Figure 1 The structure of a region R2 within the display area of the electronic device 10 (or display device) may be, for example, a cross-sectional structure corresponding to a light-emitting element, but is not limited thereto.

The circuit layer 116 may be disposed on the surface 1002 of the substrate 100. The circuit layer 116 may include thin-film transistors, capacitors, etc. Figure 1 The circuit layer 116 may include components such as signal line 101, but is not limited thereto. In some embodiments, the circuit layer 116 may be connected to... Figures 2 to 5 At least a portion of the conductive pads 108 are electrically connected, or the signal lines 101 in the circuit layer 116 may be electrically connected to at least a portion of the conductive pads 108, but this is not a limitation. The light-emitting element 118 may be disposed on the surface 1002 of the substrate 100. In one embodiment, a circuit layer 116 may be disposed between the light-emitting element 118 and the substrate 100. In this embodiment, the light-emitting element 118 may be disposed between the substrate 100 and the substrate 102, and the light-emitting element 118 may be covered by an adhesive layer 104, but this is not a limitation.
[0046] The light-emitting element 118 can be used to emit light, for example, it can emit blue light or ultraviolet light, but is not limited thereto. The light-emitting element 118 may include, but is not limited thereto, a light-emitting diode. For example, the light-emitting element 118 may include a micro LED, a sub-millimeter LED, a quantum dot LED, a nanowire LED, or a bar-type LED, but is not limited thereto.
[0047] The light-emitting element 118 may be electrically connected, for example, to a thin-film transistor or signal line 101 in the circuit layer 116. For instance, the light-emitting element 118 may include at least one bonding pad 118b, and the bonding pad 118b may be bonded to and electrically connected to a thin-film transistor or signal line 101 in the circuit layer 116, but is not limited thereto. The bonding pad 118b of the light-emitting element 118 and the other bonding pad in the circuit layer 116 may include metal or other suitable conductive materials, but are not limited thereto. Furthermore, in Figure 3 or Figure 5In this circuit, the wire 106 can be disposed on the surface 1004 of the substrate 100. The wire 106 can be electrically connected to the circuit layer 116 through the conductive pad 108, so that the integrated circuit 112 can control the light-emitting element 118 through the wire 106. In other words, the wire 106 can be electrically connected to the light-emitting element 118 and / or can be used to drive the light-emitting element 118, but is not limited thereto. In addition, in some embodiments, the material of the adhesive layer 104 can also be filled into the gaps between the bonding pads 118b to reduce the influence of moisture or oxygen on the light-emitting element 118, or to enhance the adhesion between the light-emitting element 118 and the circuit layer 116. The gaps between the bonding pads 118b can also be filled with other materials, such as adhesives or photoresist polymers, including acrylic resin, epoxy resin, phenolic resin, etc., but are not limited thereto.
[0048] Wavelength conversion layer 120, color filter layer 122, or black matrix layer 124 may be selectively disposed on the light-emitting element 118, or selectively disposed on a surface 1021 of substrate 102, or selectively disposed between substrate 102 and adhesive layer 104, but are not limited thereto. In some embodiments, a light scattering layer (not shown) may be disposed on the light-emitting element 118, but is not limited thereto. Wavelength conversion layer 120 can be used to convert the light emitted by light-emitting element 118 (e.g., convert the wavelength of the light). For example, wavelength conversion layer 120 can be used to convert the light emitted by light-emitting element 118 into red light, green light, or blue light, but is not limited thereto. For example, wavelength conversion layer 120 may include quantum dot material, phosphorescent material, fluorescent material, or a combination of the above materials, but is not limited thereto.

The color filter layer 122 may include red, green, or blue organic materials, but is not limited thereto. For example, in a red sub-pixel, the wavelength conversion layer 120 may include a quantum dot material capable of converting the light emitted by the light-emitting element 118 into red light, and the color filter layer 122 may be a red color filter layer, but is not limited thereto.

Figure 6 The wavelength conversion layer 120 and the color filter layer 122 can be disposed between adjacent black matrix layers 124. For example, the black matrix layer 124 can be made of a material that facilitates the coating of quantum dot materials in the wavelength conversion layer 120. Furthermore, the black matrix layer 124 can have a single-layer or multi-layer structure. In a multi-layer structure, different film layers can have the same or different materials.

[0059] Please refer to Figure 11 The diagram shown is a cross-sectional view of an electronic device according to a sixth embodiment of the present invention. The sixth embodiment and the fourth embodiment (as shown) Figure 9 The difference lies in that, in the sixth embodiment, the wavelength selection layer 110 can be disposed on the light-emitting element 118, or it can be disposed between the light-emitting element 118 and the wavelength conversion layer 120, but it is not limited thereto. In this embodiment, the wavelength selection layer 110 can be disposed between adjacent black matrix layers 124, but it is not limited thereto. Since the wavelength selection layer 110 in this embodiment is disposed on the side of the light-emitting element 118 that emits light, the material of the wavelength selection layer 110 can be selected to be a material that will not block the light emitted by the light-emitting element 118.
