FIG. 1AtoFIG. 1Care schematic perspective views or schematic top views of a manufacturing method of a tiling electronic device according to an embodiment of the disclosure. For clarity of the drawings and convenience of description, some elements in a tiling electronic device10are not shown inFIG. 1BandFIG. 1C. In this embodiment, a manufacturing method of the tiling electronic device10includes the following steps.

First, referring toFIG. 1AandFIG. 1B, a first electronic panel100is provided. The first electronic panel100has a side surface101surrounding a periphery of the first electronic panel100. The first electronic panel100includes a first substrate110, multiple electronic elements120, a second substrate130, multiple first bumps140, and multiple first conducting lines150. The first substrate110has a first surface111facing the second substrate130and a side surface112adjacent to the first surface111. The side surface112may surround a periphery of the first substrate110. The first substrate110includes a driving circuit (not shown) such as a transistor, a scan line, and a data line, but is not limited thereto. The first substrate110may be regarded as a driving substrate, to be electrically connected to the electronic element120and drive the electronic element120to emit light. In the embodiment, the first substrate110may be a rigid substrate, a flexible substrate, or a combination of the foregoing. For example, a material of the first substrate110may include glass, quartz, sapphire, ceramic, polycarbonate (PC), polyimide (PI), polyethylene terephthalate (PET), other suitable substrate materials, or a combination of the foregoing, but is not limited thereto.

The electronic elements120are disposed on the first surface111, and between the first substrate110and the second substrate130. The electronic elements120may include light emitting diodes of different colors, such as red light emitting diodes, green light emitting diodes, and/or blue light emitting diodes, but are not limited thereto.

The second substrate130is disposed on the first surface111of the first substrate110and the electronic elements120. The second substrate130has a side surface131, and the side surface131may surround a periphery of the second substrate130. The side surface131of the second substrate130and the side surface112of the first substrate110may form the side surface101of the first electronic panel100together. The second substrate130includes a color filter layer (such as a red filter layer, a green filter layer, a blue filter layer, or other filter layers of suitable colors, but is not limited thereto) (not shown) and/or a wavelength conversion unit (such as a quantum dot, fluorescence, phosphor, other suitable materials, or a combination of the foregoing, but is not limited thereto) (not shown), but is not limited thereto. The second substrate130may be regarded as an optical substrate, to convert light emitted by the electronic element120into red light, green light, blue light, or light of other colors, but is not limited thereto. In this embodiment, a material of the second substrate130may be the same as or similar to the material of the first substrate110described above. Thus, details in this regard will not be further reiterated in the following.

The first bumps140are disposed on the side surface101of the first electronic panel100(i.e., the side surface112of the first substrate110and the side surface131of the second substrate130). The first bumps140may be dispersed on the side surface101of the first electronic panel100. Each of the first bumps140may extend from the side surface112of the first substrate110to the side surface131of the second substrate130. In this embodiment, since the first bump140may protrude from the side surface101toward a direction away from the first electronic panel100, the first bump140may be regarded as a protrusion having a height H1. The height H1is, for example, a maximum height of the first bump140measured along a vertical direction of the side surface101. In this embodiment, a contour of the first bump140may be, for example, semicircular. However, the disclosure does not limit a shape of the contour of the first bump140. In addition, in this embodiment, a material of the first bump140may include a photoresist mixed with magnetic particles, glue, an adhesive material, or a combination of the above. Therefore, the first bump140may be regarded as a first magnetic bump, that is, the first magnetic bump disposed on the side surface101of the first electronic panel100.

The first conducting lines150are disposed on the side surface101of the first electronic panel100(i.e., the side surface112of the first substrate110and the side surface131of the second substrate130). The first conducting lines150may be dispersed on the side surface101of the first electronic panel100. Each of the first conducting lines150may extend from the side surface112of the first substrate110to the side surface131of the second substrate130. In this embodiment, the first conducting line150may be a side wiring formed on the side surface101and has a height H2. The height H2is, for example, a maximum height of the first conducting line150measured along the vertical direction of the side surface101. In this embodiment, the first conducting lines150may be electrically connected to the first substrate110, so that the first conducting lines150may be electrically connected to the electronic elements120. In this embodiment, a material of the first conducting line150may include silver paste, metallic ink, a metallic photoresist, and a metal material (including copper, aluminum, molybdenum, gold, titanium, or an alloy of the above materials), other suitable conductive materials, or a combination of the above, but is not limited thereto. The first conducting lines150may be formed by methods such as printing, spraying, sputtering, evaporation, or electroplating, but are not limited thereto.

Continuing to refer toFIG. 1AandFIG. 1B, a second electronic panel200is provided. The second electronic panel200is substantially the same as or similar to the first electronic panel100. In other words, the second electronic panel200also includes a first substrate210, multiple electronic elements220, a second substrate230, multiple second bumps240, and multiple second conducting lines250. A configuration of the first substrate210, the electronic elements220, the second substrate230, the second bumps240, and the second conducting lines250of the second electronic panel200may be substantially the same as or similar to a configuration of the first substrate110, the electronic elements120, the second substrate130, the first bumps140, and the first conducting lines150of the first electronic panel100. Thus, details in this regard will not be further reiterated in the following. The second bumps240and the second conducting lines250are disposed on a side surface201of the second electronic panel200(i.e., a side surface212of the first substrate210and a side surface231of the second substrate230). A material of the second bump240contains the magnetic particles, and may be regarded as a second magnetic bump, that is, the second magnetic bump disposed on the side surface201of the second electronic panel200. The second bump240has the height H1. The second conducting lines250may be electrically connected to the electronic elements220. The second conducting lines250has the height H2.

Referring toFIG. 1B, the first electronic panel100and the second electronic panel200are coupled or tiled through the first bumps140and the second bumps240. Specifically, in this embodiment, both the first bump140(i.e., the first magnetic bump) and the second bump240(i.e., the second magnetic bump) contain a magnetic material. Therefore, the first bump140(i.e., the first magnetic bump) may be aligned with the corresponding second bump240(i.e., the second magnetic bump), and the first bump140(i.e., the first magnetic bump) and the corresponding second bump240(i.e., the second magnetic bump) may couple the first electronic panel100and the second electronic panel200by magnetic force, so as to achieve effects of self-alignment, self-connection, or relatively easy tiling. In addition, the height H1of the first bump140(i.e., the first magnetic bump) and the second bump240(i.e., the second magnetic bump) may be greater than the height H2of the first conducting line150and the second conducting line250. Therefore, when the first electronic panel100and the second electronic panel200are tiled or coupled, the first bump140(i.e., the first magnetic bump) may be aligned and first contacted with the corresponding second bump240(i.e., the second magnetic bump) by the magnetic force, so as to ensure that the first conducting line150may also be aligned with the corresponding second conducting line250and that the first conducting line150may be electrically connected to the corresponding second conducting line250in the subsequent steps.

Continuing to refer toFIG. 1B, after the first electronic panel100and the second electronic panel200are coupled, a conducting liquid300is filled at a tiling position between the side surface101of the first electronic panel100and the side surface201of the second electronic panel200. The conducting liquid300includes a surface-modified conducting particle310. The surface-modified conducting particle310may be sensitive to an electric field, and may be polarized and arranged in the electric field under an effect of the electric field. In some embodiments, such conducting particles310, which are polarized and self-assembled under the effect of the electric field, may also be made into a film first, and attached to the side surface101of the first electronic panel100or the side surface201of the second electronic panel200by means of attachment. Then, after the electric field is applied to an electrode (such as the first conducting line150or the second conducting line250) on the side surface101or the side surface201, the conductive particles310may still be arranged and conducted by themselves along a direction of the electric field, so as to form a conducting element.

Finally, referring toFIG. 1C, multiple conducting elements320are formed, so that the first conducting lines150may be electrically connected with the second conducting lines250through the conducting elements320after the first electronic panel100and the second electronic panel200are coupled. Specifically, a method of forming the conducting elements320may include, for example, the following steps. First, the conducting liquid300is filled between the side surface101of the first electronic panel100and the side surface201of the second electronic panel200. Then, a voltage is respectively applied to the first conducting lines150and the second conducting lines250through the first substrate110and the first substrate210, so that the conducting particles310in the conducting liquid300may be gathered between the first conducting lines150and the second conducting lines250. After the liquid in the conducting liquid300is removed by baking, depressurization, or other processes, the conducting particles310gathered between the first conducting lines150and the second conducting lines250may be cured and self-assembled to form the conducting element320. So far, the tiling electronic device10of this embodiment has been manufactured.

In brief, in this embodiment, the tiling electronic device10may include the first electronic panel100and the second electronic panel200. The first electronic panel100includes the first bumps140(i.e., the first magnetic bumps) and the first conducting lines150. The first bumps140(i.e., the first magnetic bumps) and the first conducting lines150are disposed on the side surface101of the first electronic panel100. The second electronic panel200includes the second bumps240(i.e., the second magnetic bumps) and the second conducting lines250. The second bumps240(i.e., the second magnetic bumps) and the second conducting lines250are disposed on the side surface201of the second electronic panel200adjacent to the first electronic panel100. The first bumps140(i.e., the first magnetic bumps) and the corresponding second bumps240(i.e., the second magnetic bumps) are respectively attracted by one another, and the first conducting lines150are electrically connected with the second conducting lines250, respectively.

Although the first electronic panel100(the second electronic panel200) of this embodiment may include the second substrate130(or the second substrate230) as the optical substrate, the disclosure is not limited thereto. That is to say, in some embodiments, it is also unnecessary to dispose the second substrate depending on the requirements.

In the manufacturing method of the tiling electronic device10of this embodiment, although the conducting elements320are formed after the first electronic panel100and the second electronic panel200are coupled, the disclosure does not limit the above sequence of steps. That is to say, in some embodiments, the conducting elements may be formed first, and then the first electronic panel and the second electronic panel are coupled, as shown inFIG. 2AtoFIG. 2C.

In the manufacturing method of the tiling electronic device10of this embodiment, although the first bump140of the first electronic panel100and the second bump240of the second electronic panel200are coupled or tiled by the magnetic force, the disclosure does not limit the coupling or tiling method between the electronic panels. That is to say, in some embodiments, the first electronic panel and the second electronic panel may also be coupled or tiled by other methods. For example, a bonding surface of the first bump and a bonding surface of the second bump may be complementary in shape to couple or tile the first electronic panel and the second electronic panel, as shown inFIG. 3andFIG. 4.

Hereinafter, other embodiments are provided below for description. Here, it should be noted that reference numerals and a part of the content of the foregoing embodiments are used in the following embodiments. The same reference numerals are used to represent the same or similar elements, and the description of the same technical content is omitted. The description of the omitted parts may refer to the foregoing embodiments, and the same details will not be repeated in the following embodiments.

FIG. 2AtoFIG. 2Care schematic perspective views or schematic top views of a manufacturing method of a tiling electronic device according to another embodiment of the disclosure. The embodiment shown inFIG. 2AtoFIG. 2Cis similar to the embodiment shown inFIG. 1AtoFIG. 1C. Therefore, the same elements will be denoted by the same reference numerals, and details in this regard will not be further reiterated in the following. A difference between the embodiment shown inFIG. 2AtoFIG. 2Cand the embodiment shown inFIG. 1AtoFIG. 1Cis that in a manufacturing method of a tiling electronic device10aof this embodiment, multiple conducting elements (i.e., multiple first conducting elements320aand multiple second conducting elements320b) are formed before the first electronic panel100and the second electronic panel200are coupled.

Specifically, referring toFIG. 2A, in this embodiment, the patterned first conducting elements320a(or the second conducting elements320b) are first formed on a film carrier350, so that patterns of the first conducting elements320a(or the second conducting elements320b) may be the same as patterns of the first conducting lines150(or the second conducting lines250). The first conducting elements320a(or the second conducting elements320b) have a height H3. The height H3is, for example, a maximum height of the first conducting elements320a(or the second conducting elements320b) measured along a vertical direction of the film carrier350. In this embodiment, materials of the first conducting element320aand the second conducting element320bmay include a photoresist mixed with metallic particles or metallic flakes. A material of the metallic particles or the metallic flakes may be, for example, silver, copper, gold, titanium, palladium, platinum, other suitable metal materials, or alloys of the above materials. A material of the film carrier350may include polyethylene (PE), polycarbonate, polyimide, or polyolefin (PO), etc., but is not limited thereto.

Referring toFIG. 2B, the first conducting elements320a(or the second conducting elements320b) on the film carrier350are aligned and attached on the first conducting lines150(or the second conducting lines250) of the first electronic panel100(or second electronic panel200). Next, after the first conducting element320a(or the second conducting element320b) is fixed on the first conducting line150(or the second conducting line250) by heating, for example, the film carrier350is removed. At this time, the first conducting elements320aare respectively formed on the first conducting lines150, and the second conducting elements320bare respectively formed on the second conducting lines250.

Referring toFIG. 2C, the first electronic panel100and the second electronic panel200are coupled or tiled through the first bumps140and the second bumps240. In this embodiment, the height H3of the first conducting element320aand the second conducting element320bmay be greater than or equal to the height H1of the first bump140and the second bump240. Therefore, when the first electronic panel100and the second electronic panel200are tiled, and the first bump140is aligned with the corresponding second bump240, it may be ensured that the first conducting element320amay also be aligned and contacted with the corresponding second conducting element320b, so that the first conducting line150may be electrically connected with the second conducting line250through the first conducting element320aand the second conducting element320bafter the first electronic panel100and the second electronic panel200are tiled. In some embodiments, the first conducting element320aand the second conducting element320bmay have compressibility. Therefore, when the height H3of the first conducting element320aand the second conducting element320bis greater than the height H1of the first bump140and the second bump240, the first bump140and the second bump240may be attracted by each other by pressurizing the first conducting element320aand the second conducting element320b. So far, the tiling electronic device10aof this embodiment has been manufactured.

FIG. 3is a schematic top view of a tiling electronic device according to another embodiment of the disclosure.FIG. 4is a schematic top view of a tiling electronic device according to another embodiment of the disclosure. Referring to bothFIG. 1CandFIG. 3or referring to bothFIG. 2CandFIG. 4, a tiling electronic device10bofFIG. 3is substantially similar to the tiling electronic device10ofFIG. 1C, and a tiling electronic device10cofFIG. 4is substantially similar to the tiling electronic device10aofFIG. 2C. Therefore, the same and similar components in the two embodiments will not be repeated in the following. A main difference between the tiling electronic device10bofFIG. 3and the tiling electronic device10and a main difference between the tiling electronic device10cofFIG. 4and the tiling electronic device10aare that in the tiling electronic device10bofFIG. 3and the tiling electronic device10cofFIG. 4, multiple first bumps140band multiple second bumps240bcouple the first electronic panel100and the second electronic panel200by a complementary bonding surface.

Specifically, referring toFIG. 3andFIG. 4, the first bump140band the second bump240bmay be the first magnetic bump and the second magnetic bump containing magnetic particles, respectively. The first bump140b(i.e., the first magnetic bump) and the second bump240b(i.e., the second magnetic bump) may have three-dimensional bonding surfaces, respectively. The three-dimensional bonding surface may be a concave surface or a convex surface, but is not limited thereto, as long as the three-dimensional bonding surface of the first bump140b(i.e., the first magnetic bump) may be complementary to the three-dimensional bonding surface of the second bump240b(i.e., the second magnetic bump). In this embodiment, at the tiling position between the first electronic panel100and the second electronic panel200, the first bump140b(i.e., the first magnetic bump) and the corresponding second bump240b(i.e., the second magnetic bump) should respectively have the complementary bonding surfaces, and the first bump140b(i.e., the first magnetic bump) and the corresponding second bump240b(i.e., the second magnetic bump) should be alternately arranged with each other. Therefore, at the tiling position between the first electronic panel100and the second electronic panel200, when the bonding surface of the first bump140b(i.e., the first magnetic bump) is a concave surface, the bonding surface of the second bump240b(i.e., the second magnetic bump) is a convex surface that may be complementary to the concave surface. In this way, it may be ensured that the first bump140(i.e., the first magnetic bump) may be aligned with the second bump240(i.e., the second magnetic bump), so as to achieve the effects of self-alignment, self-connection, or relatively easy tiling.

In this embodiment, the first bump140band the second bump240bmay be the first magnetic bump and the second magnetic bump containing the magnetic particles, respectively, but are not limited thereto. That is to say, in some embodiments, the first bump and the second bump may not have magnetism, as long as the bonding surface of the first bump may be complementary to the bonding surface of the second bump.

In some embodiments, at the tiling position between the first electronic panel100and the second electronic panel200, the first bump (i.e., the first magnetic bump) may include a first bump having the concave surface and a first bump having the convex surface (not shown), and the second bump (i.e., the second magnetic bump) may include a second bump having the concave surface and a second bump having the convex surface (not shown). The first bump having the concave surface and the first bump having the convex surface may be alternately arranged with each other in an extending direction of the side surface (i.e., the side surface of the first substrate and the side surface of the second substrate) of the first electronic panel, and the second bump having the concave surface and the second bump having the convex surface may be alternately arranged with each other in an extending direction of the side surface (i.e., the side surface of the first substrate and the side surface of the second substrate) of the second electronic panel. The first bump having the concave surface may be aligned and complementary to the second bump having the convex surface, and the first bump having the convex surface may be aligned and complementary to the second bump having the concave surface, so as to achieve the effects of self-alignment, self-connection, or relatively easy tiling.

FIG. 5AtoFIG. 5Bare schematic perspective views or schematic top views of a manufacturing method of a tiling electronic device according to another embodiment of the disclosure. The embodiment shown inFIG. 5AtoFIG. 5Bis similar to the embodiment shown inFIG. 2AtoFIG. 2C. Therefore, the same elements will be denoted by the same reference numerals, and details in this regard will not be further reiterated in the following. A difference between the embodiment shown inFIG. 5AtoFIG. 5Band the embodiment shown inFIG. 2AtoFIG. 2Cis that in a manufacturing method of a tiling electronic device10dof this embodiment, a first magnetic bump140dand a first conducting element330are combined to form a first composite element160, and a second magnetic bump240dand a second conducting element340are combined to form a second composite element260.

Specifically, referring toFIG. 5A, in this embodiment, the first composite elements160or the second composite elements260are formed on the film carrier350first. The first composite elements160are formed by respectively embedding the first magnetic bumps140din the first conducting elements330, so that the first conducting elements330may surround peripheries of the first magnetic bumps140d. The second composite elements260are formed by respectively embedding the second magnetic bumps240din the second conducting elements340, so that the second conducting elements340may surround peripheries of the second magnetic bumps240d.

Next, the first composite elements160on the film carrier350are aligned and attached on the first conducting lines150of the side surface101of a first electronic panel100d, and the second composite elements260on the film carrier350are aligned and attached on the second conducting lines250of the side surface201of a second electronic panel200d. Then, after the first composite element160is fixed on the side surface101of the first electronic panel100d, and the second composite element260is fixed on the side surface201of the second electronic panel200d, the film carrier350is removed.

Referring toFIG. 5B, the first electronic panel100dand the second electronic panel200dare coupled or tiled through the first composite elements160and the second composite elements260. In this embodiment, the first composite element160has the first magnetic bump140d, and the second composite element260has the second magnetic bump240d. Therefore, the first composite element160may be aligned with the second composite element260, and the first composite element160and the second composite element260may couple the first electronic panel100dand the second electronic panel200dby the magnetic force, so as to achieve the effects of self-alignment, self-connection, and relatively easy tiling.

In addition, the first composite element160has the first conducting element330covered outside the first magnetic bump140d, and the second composite element260has the second conducting element340covered outside the second magnetic bump240d. Therefore, when the first electronic panel100dand the second electronic panel200dare tiled, and the first composite element160is aligned with the corresponding second composite element260, it may be ensured that the first conducting element330may also be aligned and contacted with the corresponding second conducting element340, so that the first electronic panel100dmay be electrically connected with the second electronic panel200dthrough the first conducting element330and the second conducting element340after being tiled. So far, the tiling electronic device10dof this embodiment has been manufactured.

FIG. 6is a schematic perspective view of a first composite element and a second composite element according to another embodiment of the disclosure. Referring to bothFIG. 5AandFIG. 6, a first composite element160eand a second composite element260ein this embodiment are similar to the first composite element160and the second composite element260inFIG. 5A. However, a main difference between the two is that a first magnetic bump140eand a first conducting element330ein the first composite element160eare disposed side by side, and a second magnetic bump240eand a second conducting element340ein the second composite element260eare disposed side by side.

Specifically, referring toFIG. 6, in this embodiment, the first composite element160eis formed by combining the first magnetic bump140eand the first conducting element330e, and the second composite element260eis formed by combining the second magnetic bump240eand the second conducting element340e. One of the first magnetic bumps140eand one of the first conducting elements330eare in contact with each other, and one of the second magnetic bumps240eand one of the second conducting elements340eare in contact with each other.

Based on the above, in the electronic panel, the tiling electronic device, and the manufacturing method thereof in the disclosure, the first bump of the first electronic panel and the second bump of the second electronic panel may be aligned by the magnetic force or the complementary bonding surface. Therefore, the first electronic panel and the second electronic panel may be coupled or tiled, thereby achieving the effects of self-alignment, self-connection, or relatively easy tiling. In addition, in some embodiments, the height of the first bump and the second bump may be greater than the height of the first conducting line and the second conducting line. Therefore, when the first electronic panel and the second electronic panel are tiled or coupled, the first bump may be aligned and first contacted with the corresponding second bump by the magnetic force or the complementary bonding surface, so as to ensure that the first conducting line may also be aligned with the corresponding second conducting line, and that the first conducting line may be electrically connected to the corresponding second conducting line in the subsequent steps. In addition, in some embodiments, the height of the first conducting element and the second conducting element may be greater than or equal to the height of the first bump and the second bump. Therefore, when the first electronic panel and the second electronic panel are tiled, and the first bump is aligned with the corresponding second bump, it may be ensured that the first conducting element may also be aligned and contacted with the corresponding second conducting element, so that the first conducting line may be electrically connected with the second conducting line through the first conducting element and the second conducting element after the first electronic panel and the second electronic panel are tiled.
