[0056] The present disclosure can be understood with reference to the following detailed description and drawings, in which like reference numerals represent like elements, and in which: it should be noted that in order to facilitate an easy understanding of the present disclosure and for the sake of brevity only the parts of the electronic device are shown in the drawings and the specific elements in the drawings are not drawn according to the actual scale. In addition, the number and size of the elements in the drawings are only for illustration and are not intended to limit the scope of the present disclosure.

[0057] In the following description and claims, the terms "comprise" and "include" and the like are used in an open-ended fashion, and thus should be interpreted to mean "including, but not limited to...".

[0058] Certain terminology is used in the present disclosure for the purpose of reference only and thus is not intended to be limiting. For example, terms such as "upper", "lower", "above", and "below" refer to the apparatus as oriented in the drawings. The terminology includes the words specifically noted above, derivatives thereof, and words of similar import. The word "comprising" is used herein to mean including the elements or steps that follow the word, but not excluding others.

[0059] When an element such as a layer, region, or substrate is referred to as being "on" or extending "onto" another element, it can be directly on or extend directly onto the other element or intervening elements can also be present. In contrast, when an element is referred to as being "directly on" or extending "directly onto" another element, there are no intervening elements present. Also, when an element is referred to as being "coupled" to or "connected" to another element, it can be directly coupled or connected to the other element or intervening elements can be present. In contrast, when an element is referred to as being "directly coupled" or "directly connected" to another element, there are no intervening elements present.

[0060] As used herein, the terms "about," "substantially," and variations thereof, are intended to allow for a number of variations appropriate to the field of the disclosure, while maintaining the general purpose of the terms. As used herein, the term "about" means that quantities, dimensions, notations, and other applied values and such factors specify the value that, without being exactly accurate, is approximatively or reasonably close to the true intended value within a range of values and / or variations that one of ordinary skill in the art would consider reasonable in light of the specific field, such that the intended end result is not untoward or without merit. As used herein, the term "substantially" means that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations, if any, are sufficiently minor as to not modify the intended end result in any material way. As used herein, the term "between" is intended to mean that the range includes the first value, the second value, and all values therebetween.

[0061] It will be understood that, although the terms "first," "second," etc. can be used herein to describe various elements, layers and / or sections, these elements, layers and / or sections should not be limited by these terms. These terms are only used to distinguish one element, layer or section from another. Thus, a first element, layer or section discussed below could be termed a second element, layer or section without departing from the teachings of some embodiments. Additionally, some of the elements, layers sections or portions can be combined, eliminated, or modified, and the meaning of the word "comprising" or "comprises," as used herein, includes possibilities of such modifications or replacements.

[0062] In the present disclosure, the measurement of thickness, length and width can be obtained by optical microscope measurement, and the thickness can be measured by cross-sectional image in electron microscope, but not limited thereto. In addition, there can be some error between any two values or directions used for comparison. If a first value is equal to a second value, it is implied that there can be about 10% error between the first value and the second value; if a first direction is perpendicular to a second direction, the angle between the first direction and the second direction can be between 80 degrees and 100 degrees; if a first direction is parallel to a second direction, the angle between the first direction and the second direction can be between 0 degrees and 10 degrees.

[0063] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0064] It should be noted that the technical solutions provided by different embodiments below can be replaced, combined or mixed to constitute another embodiment without violating the spirit of the disclosure.

[0065] In this disclosure, length and width can be measured using an optical microscope, and thickness can be measured from cross-sectional images using an electron microscope, but these methods are not limited to these.

For example, the shape of the power supply lines 111 and 111a is merely illustrative.

[0072] Please also refer to Figure 1A and Figure 1B The power supply circuit 120 can be disposed on the bottom surface 104 and the side surface 106a of the substrate 100.

In some embodiments, at least two dispersion terminals can disperse the power to different portions (i.e., the first portion 1111 and the second portion 1112 of the power line 111) of the array circuit 110.In some embodiments, the power input terminal 121 can correspond to or be electrically connected to at least two distributed terminals (e.g., the distributed terminal 122 and the distributed terminal 123), for example, and the power input terminal 121 can be electrically connected to two of the at least two distributed terminals (e.g., the distributed terminal 122 and the distributed terminal 123) through the first wire 124 and the second wire 125, respectively, to different portions (i.e., the first portion 1111 and the second portion 1112) of the power line 111 and / or light emitting elements (the light emitting elements L1, L2, L3) through the distributed terminals, but the application is not limited thereto. In some embodiments, the first portion 1111 and the second portion 1112 can be electrically connected to each other. In some embodiments, the first portion 1111 and the second portion 1112 can be formed by the same conductive layer.

[0074] In some embodiments, the power supply circuit (e.g., the power supply circuit 120 or the power supply circuit 120a) can receive, for example, a current provided by an electronic component (e.g., the electronic component C1 or the electronic component C2), and the power is provided to the array circuit 110 through the power supply circuit (e.g., the power supply circuit 120 or the power supply circuit 120a). The electronic component C1 or the electronic component C2 can include a wafer or a flexible printed circuit board (FPC), but is not limited thereto. Specifically, in some embodiments, a power input terminal (e.g., the power input terminal 121 or the power input terminal 121a) in the power supply circuit (e.g., the power supply circuit 120 or the power supply circuit 120a) can distribute the power inputted or provided by the corresponding electronic component (e.g., the electronic component C1 or the electronic component C2) to a first lead (e.g., the first lead 124 or the first lead 124a) and a second lead (e.g., the second lead 125 or the second lead 125a). Then, the power is transmitted by the first lead (e.g., the first lead 124 or the first lead 124a) and the second lead (e.g., the second lead 125 or the second lead 125a) to at least two distribution terminals, respectively, such as the distribution terminal 122 (or the distribution terminal 122a) and the distribution terminal 123 (or the distribution terminal 123a). Then, the power is distributed by the at least two distribution terminals to different parts of the array circuit 110, respectively, such as a first part (e.g., the first part 1111 or the first part 1111a) and a second part (e.g., the second part 1112 or the second part 1112a) of the array circuit 110. For example, the power input terminal (e.g., the power input terminal 121 or the power input terminal 121a) can correspond to two distribution terminals, respectively, such that the two distribution terminals can distribute the power to the different parts of the array circuit 110, such as the first part (the first part 1111 or the first part 1111a) and the second part (the second part 1112 or the second part 1112a) of the array circuit 110, in a substantially 1:1 ratio, but is not limited thereto. In other words, the distribution terminal (e.g., the distribution terminal 122 or the distribution terminal 122a) can transmit substantially 1 / 2 of the power (or current) to the first part (e.g., the first part 1111 or the first part 1111a) of the array circuit 110, and the other distribution terminal (e.g., the distribution terminal 123 or the distribution terminal 123a) can transmit substantially 1 / 2 of the power (or current) to the second part (e.g., the second part 1112 or the second part 1112a) of the array circuit 110.

[0075] In some embodiments, the dispersion terminal 122 is, for example, adjacent to the side surface 106c of the substrate 100, the dispersion terminal 123 is away from the side surface 106c of the substrate 100, and other terminals (e.g., the transmission terminal 132) are further provided between the dispersion terminal 122 and the dispersion terminal 123, so that the dispersion terminal 122 and the dispersion terminal 123 can be dispersed on different regions of the side surface 106a of the substrate 100, but not limited thereto. In some embodiments, the dispersion terminal 122a is, for example, adjacent to the side surface 106d of the substrate 100, the dispersion terminal 123a is away from the side surface 106d of the substrate 100, and other terminals (e.g., the transmission terminal 132a) are further provided between the dispersion terminal 122a and the dispersion terminal 123a, so that the dispersion terminal 122 and the dispersion terminal 123 can be dispersed on different regions of the side surface 106a of the substrate 100, but not limited thereto. As described above, since the dispersion terminal (e.g., the dispersion terminal 122 or the dispersion terminal 122a) and the other dispersion terminal (e.g., the dispersion terminal 123 or the dispersion terminal 123a) can be dispersed on different regions of the side surface 106a of the substrate 100, the power (or current) transmitted or provided by the power supply circuit (e.g., the power supply circuit 120 or the power supply circuit 120a) can be uniformly dispersed to the first portion (e.g., the first portion 1111 or the first portion 1111a) and the second portion (e.g., the second portion 1112 or the second portion 1112a) of the array circuit 110 through at least two electrically connected or corresponding dispersion terminals, respectively, so that the power (or current) can be uniformly distributed in the array circuit 110, and the power can be more uniformly transmitted to different light emitting elements (e.g., the light emitting elements L1, L2, and L3), so as to improve the brightness uniformity of the light emitted by the light emitting elements. Therefore, compared with the existing electronic device, since the power can only be transmitted through a single circuit path, the problem of voltage drop (IR drop) is prone to occur, and the brightness of the light emitting elements is not uniform. The electronic device of the present embodiment can improve the above-mentioned problems of voltage drop or brightness non-uniformity of the light emitting elements by providing at least two circuit paths to transmit the power (or current).

[0076] Please continue to refer to Figure 1A and Figure 1BIn some embodiments, the power supply circuit 120 is disposed adjacent to the power supply circuit 120a on the bottom surface 104. In some embodiments, the power input terminal 121 of the power supply circuit 120 is, for example, distanced from the power input terminal 121a of the power supply circuit 120a, which is, for example, distanced from the power supply circuit 120, but not limited thereto. In some embodiments, the power input terminal 121, the first conductive wire 124, and the dispersion terminal 122 of the power supply circuit 120 are adjacent to the side surface 106c of the substrate 100. In some embodiments, the dispersion terminal 123 of the power supply circuit 120 is distanced from the side surface 106c of the substrate 100. In some embodiments, the power input terminal 121a, the first conductive wire 124a, and the dispersion terminal 122a of the power supply circuit 120a are adjacent to the side surface 106d of the substrate 100. In some embodiments, the dispersion terminal 123a of the power supply circuit 120a is distanced from the side surface 106d of the substrate 100.

[0077] Referring again to Figure 1B The display panel 10 of the present embodiments further includes a signal supply circuit (e.g., the signal supply circuit 130 or the signal supply circuit 130a) disposed on the bottom surface 104 of the substrate 100. The signal supply circuit (e.g., the signal supply circuit 130 or the signal supply circuit 130a) can, for example, receive a signal (e.g., a scan signal or a data signal, but not limited thereto) provided by an electronic element (e.g., the electronic element C1 or the electronic element C2) and provide the signal to the array circuit 110 through the signal supply circuit (e.g., the signal supply circuit 130 or the signal supply circuit 130a). The signal supply circuit (e.g., the signal supply circuit 130 or the signal supply circuit 130a) can have at least one signal input terminal (e.g., the signal input terminal 131 or the signal input terminal 131a), at least one transmission terminal (e.g., the transmission terminal 132 or the transmission terminal 132a), and at least one third conductive wire (e.g., the third conductive wire 133 or the third conductive wire 133a), but not limited thereto. In some embodiments, the signal input terminal (e.g., the signal input terminal 131 or the signal input terminal 131a) can be electrically connected to the transmission terminal (e.g., the transmission terminal 132 or the transmission terminal 132a) through the third conductive wire (e.g., the third conductive wire 133 or the third conductive wire 133a).

[0078] Since the components of the signal supply circuit 130a are similar to those of the signal supply circuit 130, the signal supply circuit 130 is described below as an example. In some embodiments, the signal input terminal 131 and the third conductive line 133 of the signal supply circuit 130 can be disposed on the bottom surface 104 of the substrate 100, and the transmission terminal 132 can be disposed on the side surface 106a of the substrate 100. In some embodiments, the transmission terminal (e.g., the transmission terminal 132 or the transmission terminal 132a) is disposed on a side surface (e.g., the side surface 106b) and between two of the at least two distributed terminals, such as between the distributed terminal 122 and the distributed terminal 123, and between the distributed terminal 122' and the distributed terminal 123'. In some embodiments, the transmission terminal (e.g., the transmission terminal 132 or the transmission terminal 132a) can transmit a signal to the array circuit 110. In some embodiments, the at least one third conductive line 133 can be disposed between the first conductive line 124 and the second conductive line 125 of the power supply circuit 120. In some embodiments, the first conductive line 124, the second conductive line 125, and / or the third conductive line 133 can be formed from the same film layer (e.g., a conductive layer), but the application is not limited thereto. Please also refer to Figure 1A Figure 1B In some embodiments, a signal can be transmitted by the signal supply circuit 130 to the corresponding or electrically connected third conductive line 133, and further transmitted to the corresponding or electrically connected transmission terminal 132, to transmit the signal to the signal line 112 of the array circuit 110, to drive the corresponding or electrically connected light emitting element (e.g., the light emitting element L1, L2, L3) through the signal line 112, but the application is not limited thereto. In some embodiments, as viewed in the normal direction of the bottom surface 104 of the substrate 100, the power input terminal (e.g., the power input terminal 121 or the power input terminal 121a), the first conductive line (e.g., the first conductive line 124 or the first conductive line 124a), and the second conductive line (e.g., the second conductive line 125 or the second conductive line 125a) are connected to each other and surround the signal input terminal (e.g., the signal input terminal 131 or the signal input terminal 131a) and the third conductive line (e.g., the third conductive line 133 or the third conductive line 133a).

[0079] In some embodiments (such as Figure 1B ​In some embodiments, at least one electronic component (e.g., electronic component C1 or electronic component C2) can be disposed on the bottom surface 104 of the substrate 100, and the electronic component (e.g., electronic component C1 or electronic component C2) can be electrically connected or bonded to the signal input terminals (e.g., signal input terminal 131 or signal input terminal 131a) and the power input terminals (e.g., power input terminal 121 or power input terminal 121a). In some embodiments, the at least one electronic component (e.g., electronic component C1 or electronic component C2) can have a plurality of bonding pads (not shown) that can respectively correspond to the signal input terminals and / or the power input terminals, and the bonding pads can be electrically connected or bonded to the corresponding signal input terminals and / or the power input terminals, for example.

[0080] In some embodiments, the power input terminals (e.g., power input terminal 121 or power input terminal 121a) of the present disclosure can correspond to or be electrically connected to two distributed terminals, but the present disclosure does not limit the number of distributed terminals to which the power input terminals can correspond. In some embodiments, the power input terminals can correspond to at least two or more distributed terminals, so that the at least two or more distributed terminals distribute power to different parts of the array circuit.

[0081] Although all the distributed terminals of the present embodiment are disposed on the same side surface (e.g., side surface 106a), the present disclosure does not limit the disposition position of the distributed terminals. In some embodiments, different distributed terminals corresponding to the same power input terminal can be respectively disposed on the same or different side surfaces. For example (not shown), different distributed terminals (e.g., distributed terminal 122 and distributed terminal 123) corresponding to the power input terminal 121 can be respectively disposed on the same or different side surfaces (including side surface 106a, side surface 106b, side surface 106c, and / or side surface 106d), or different distributed terminals (e.g., distributed terminal 122a and distributed terminal 123a) corresponding to the power input terminal 121a can be respectively disposed on the same or different side surfaces (including side surface 106a, side surface 106b, side surface 106c, and / or side surface 106d).

[0082] Although the dispersion terminals 122 and 123 corresponding to or electrically connected to the power input terminal 121 of the present embodiment can respectively transmit approximately 1 / 2 of the power (or current) to the first portion 1111 and the second portion 1112 of the array circuit 110, and the dispersion terminals 122a and 123a corresponding to or electrically connected to the power input terminal 121a can respectively transmit approximately 1 / 2 of the power (or current) to the first portion 1111a and the second portion 1112a of the array circuit 110, the present disclosure is not limited to the proportion of the power (or current) that the dispersion terminals can transmit. For example, when the power input terminal 121 corresponds to two dispersion terminals (e.g., the dispersion terminals 122 and 123), the two dispersion terminals approximately divide the power in a 1:1 proportion to the different portions (e.g., the first portion 1111 and the second portion 1112) of the array circuit 110.

[0083] Specifically, since the voltage transmitted by the dispersion terminals is the same as the voltage provided by the power input terminal to which the dispersion terminals correspond or are electrically connected, and the amount of current and / or power that the dispersion terminals can distribute or transmit can be approximately divided in proportion to the number of dispersion terminals electrically connected to the power input terminal. For example, when the number of dispersion terminals electrically connected to the power input terminal is n, the proportion of the current (and / or power) that the dispersion terminals can distribute is approximately 1 / n.

[0084] Although three signal input terminals 131 (or input terminals 131a), transmission terminals 132 (or transmission terminals 132a), and third conductive lines 133 (or third conductive lines 133a) are shown, the present disclosure is not limited to the number of signal input terminals, transmission terminals, and third conductive lines.

[0085] In addition, the display panel 10 of the present embodiment can also be spliced into a spliced display device (not shown). That is, the spliced display device of the present embodiment can include a plurality of display panels 10.

The description of the omitted parts can be referred to the foregoing embodiments, and the following embodiments will not be repeated.

Figure 1BThe display panel 10 is the same as that in both embodiments, so the same and similar components will not be described again here. The main difference between the display panel 10a in this embodiment and the display panel 100 in this embodiment is that the display panel 10a in this embodiment also includes an insulating layer 140. For details, please refer to Figure 2A An insulating layer 140 may be disposed on the bottom surface 104 of the substrate 100 to cover or protect the circuit disposed on the bottom surface 104, including power input terminal 121, power input terminal 121a, first wire 124, first wire 124a, second wire 125, second wire 125a, signal input terminal 131, signal input terminal 131a, third wire 133, third wire 133a, or other electronic components. In some embodiments, the insulating layer 140 may selectively cover or protect portions of electronic components (e.g., electronic component C1 or electronic component C2).

[0088] In some embodiments, the insulating layer 140 may be disposed on a side surface (e.g., side surface 106a) of the substrate 100 to cover and protect circuits disposed on the side surface (e.g., side surface 106a or other side surfaces), including distributed terminals 122, distributed terminals 122a, distributed terminals 123, distributed terminals 123a, transmission terminals 132, transmission terminals 132a, or other electronic components. In this embodiment, the insulating layer 140 may be a single-layer or multi-layer structure, and the material of the insulating layer 140 may include organic materials, inorganic materials, or combinations thereof, but is not limited thereto.

[0089] Please refer to Figure 2B In this embodiment, directions X, Y, and Z are different directions. For example, direction X is approximately the extension direction of the cross-section line A-A', direction Y is approximately the normal direction of the substrate 100, and direction Z may be approximately the extension direction of the first conductor 124, the first conductor 124a, the third conductor 133, and the third conductor 133a. Direction X is approximately perpendicular to direction Y, direction Y is approximately perpendicular to direction Z, and direction Z is approximately perpendicular to direction X, but this is not a limitation. In this embodiment, the first conductor 124 (or the first conductor 124a) has a width W1, and the third conductor 133 (or the third conductor 133a) has a width W2. The width W1 may be greater than or equal to the width W2, but this is not a limitation. In this embodiment, the width W1 is, for example, the maximum width of the first conductor 124 (or the first conductor 124a) in direction X, and the width W2 is, for example, the maximum width of the third conductor 133 (or the third conductor 133a) in direction X.
