For example, the multiple signal lines include, for example, scan lines, data lines or other wires. Part of the signal lines can be electrically connected to thin film transistors (TFT). In this embodiment, the thin film transistor can be electrically connected to the scan line SL or the data line DL. The thin film transistor includes, for example, a semiconductor channel layer, a gate (electrically connected to the scan line), and a source and a drain electrically connected to the semiconductor channel layer. The material of the semiconductor channel layer includes, for example, amorphous silicon, low temperature polysilicon (LTPS) or metal oxide, or a combination of the above materials, but the present disclosure is not limited thereto. In some embodiments, different thin film transistors may have the above different semiconductor materials. In addition, the thin film transistor may include a top gate transistor, a bottom gate transistor, a dual gate transistor and a double gate transistor as needed, but is not limited thereto.

[0024] In the present embodiment, the electronic device 10 may include multiple insulating layers (not shown) and multiple circuit layers disposed on the insulating layers or between the multiple insulating layers. The insulating layer may be a single layer or a multi-layer structure, and may, for example, include an organic material, an inorganic material, or a combination thereof, but is not limited thereto. The organic material may include polyethylene terephthalate (PET), polyethylene (PE), polyethersulfone (PES), polycarbonate (PC), polymethylmethacrylate (PMMA), polyimide (PI), photosensitive polyimide (PSPI), or a combination thereof, and the inorganic material may include silicon nitride, silicon oxide, silicon oxynitride, or a combination thereof, but is not limited thereto.

[0025] In this embodiment, the multi-layer circuit layer ML can be applied as the above-mentioned signal line, including a scan line, a data line or other conductive line. The material of the multi-layer circuit layer ML may include a transparent conductive material or a non-transparent conductive material, such as indium tin oxide, indium zinc oxide, indium oxide, zinc oxide, tin oxide, metal material (such as aluminum, molybdenum, copper, silver, etc.), other suitable materials or the above combination, but not limited thereto. Figure 1 As shown, the multi-layer circuit layer ML may include a first circuit layer M1. The first circuit layer M1 may include, for example, a plurality of scan lines SL, SL', and portions of the plurality of scan lines SL, SL' substantially extend along the X axis, but the present invention is not limited thereto.

[0026] In this embodiment, the multi-layer circuit layer ML may further include a second circuit layer M2. On the Z axis, the second circuit layer M2 is disposed above the first circuit layer M1, and the second circuit layer M2 partially overlaps the first circuit layer M1. The second circuit layer M2 may, for example, include a plurality of data lines DL, DL', and portions of the plurality of data lines DL, DL' extend substantially along the Y axis, but are not limited thereto. From another perspective, the first circuit layer M1 and the second circuit layer M2 may be arranged alternately.

[0027] The multilayer circuit layer ML may further include a third circuit layer M3 and a fourth circuit layer M4. On the Z axis, the third circuit layer M3 is disposed above the second circuit layer M2, and the fourth circuit layer M4 is disposed above the third circuit layer M3. The third circuit layer M3 partially overlaps the second circuit layer M2, and the fourth circuit layer M4 partially overlaps the third circuit layer M3. The third circuit layer M3, for example, includes a circuit line or a bridge line 130, and a portion thereof extends approximately along the X axis, and another portion extends approximately along the Y axis. The fourth circuit layer M4, for example, includes a bonding pad 140 (pad) or a shared circuit line 142, and a portion thereof extends approximately along the X axis, and another portion extends approximately along the Y axis, but is not limited thereto. In the present embodiment, a portion of the third circuit layer M3 may be electrically connected to a portion of the second circuit layer M2 through a through hole (not shown) on an insulating layer, and a portion of the fourth circuit layer M4 may be electrically connected to a portion of the third circuit layer M3 through a through hole (not shown) on another insulating layer. Under the above setting, the fourth circuit layer M4 includes multiple bonding pads 140, a portion of the bonding pads 140 can be connected to the shared circuit line 142 (which can be located in the fourth circuit layer M4), and another portion of the bonding pads 140 can be electrically connected to the data line DL of the second circuit layer M2 through the bridge line 130, but is not limited to this.

[0028] In this embodiment, the opening area 11 is defined as an area substantially surrounded by two adjacent data lines DL and data line DL' of two adjacent units PX and units PX', respectively. Figure 1 As shown). For example, the opening area 11 can be an area that allows ambient light to penetrate. In other embodiments, the opening area 11 can be defined by the area surrounded by two adjacent data lines DL, DL' and two adjacent scan lines SL, SL'. In other words, the opening area 11 does not substantially overlap the circuit layer ML (including the first circuit layer M1, the second circuit layer M2, the third circuit layer M3 or the fourth circuit layer M4). In some embodiments, the opening area 11 is, for example, an octagon, but is not limited to this. In other embodiments, the opening area 11 can also be a triangle, a rectangle, a polygon, a star, a circle or an irregular shape, and the present disclosure is not limited to this.

[0029] In the present embodiment, the opening area 11 may be surrounded by the non-opening area 13. At least a portion of the circuit layer ML (including the first circuit layer M1, the second circuit layer M2, the third circuit layer M3 or the fourth circuit layer M4) may overlap the non-opening area 13. In other words, at least a portion of the scan line SL, the data line DL, the bridge line 130, the bonding pad 140 or the shared circuit line 142 may overlap the non-opening area 13, but is not limited thereto.

[0030] In some embodiments, the main bonding area 210 and the backup bonding area 220 of the unit PX can be set corresponding to the non-opening area 13. In other words, the main bonding area 210 and at least one backup bonding area 220 overlap the non-opening area 13 accordingly. For example, multiple main bonding areas 210 can overlap the second circuit layer M2, the third circuit layer M3 or the fourth circuit layer M4. The backup bonding area 220 can overlap the second circuit layer M2, the third circuit layer M3 or the fourth circuit layer M4. Each main bonding area 210 includes two bonding pads 140. Each backup bonding area 220 includes two bonding pads 140. In the present embodiment, the bonding pads 140 can be used as electrodes for connecting electronic components. The electronic component may, for example, include a blue light-emitting diode 300B, a green light-emitting diode 300G or a red light-emitting diode 300R, but is not limited thereto. That is, each main bonding area 210 can be used to bond a blue LED 300B, a green LED 300G, or a red LED 300R, and in the top view direction, at least a portion of the main bonding area 210 overlaps with the electronic component (for example: a blue LED 300B, a green LED 300G, or a red LED 300R). Each backup bonding area 220 can be used to bond a blue LED 300B, a green LED 300G, or a red LED 300R, but is not limited thereto. In this embodiment, the number of backup bonding areas 220 is less than the number of main bonding areas 210. For example, Figure 1 It is shown that three main bonding areas 210 can be arranged in sequence along the Y axis and overlap the non-opening area 13, and two backup bonding areas 220 can be arranged along the Y axis following the main bonding areas 210 and overlap the non-opening area 13, but the present disclosure is not limited to this. That is, the main bonding area 210 and the backup bonding area 220 are connected or arranged adjacent to each other. In other embodiments, the backup bonding area 220 can be staggered with the main bonding area 210, or the backup bonding area 220 can be arranged at opposite ends of the main bonding area 210, but it is not limited to this. In addition, it should be noted that Figure 1 The number of the main joint areas 210 and the number of the backup joint areas 220 shown are only for illustration and are not intended to specifically limit the present disclosure. In other embodiments, the number of the main joint areas 210 may be two, four or more, and the number of the backup joint areas 220 may be one, three or more, and the present disclosure is not limited thereto.

[0031] In the present embodiment, the definition of the unit PX is, for example, the area between the center lines L and L' of the opening areas 11 and 11' on the opposite sides of the main joint area 210 and the backup joint area 220 on the X-axis in the non-opening area 13. For example, the opening area 11 on the left side of the main joint area 210 and the backup joint area 220 is separated into two halves of equal area by the center line L. The opening area 11' on the right side of the main joint area 210 and the backup joint area 220 is separated into two halves of equal area by the center line L'. The area between the center line L of the opening area 11 and the center line L' of the opening area 11' can be called a unit PX. That is, the unit PX includes the main joint area 210 and the backup joint area 220 overlapping the non-opening area 13 and half of the two opening areas 11 and 11' on the opposite sides thereof, but is not limited thereto.

[0032] In this embodiment, the electronic device 10 may further include a light shielding layer BM ( Figure 1 (not shown). At least a portion of the light shielding layer BM corresponds to the overlapping non-opening area 13. For example, the light shielding layer BM can be disposed on the substrate 100 and disposed below the circuit layer ML on the Z axis. That is, at least a portion of the first circuit layer M1, the second circuit layer M2, the third circuit layer M3 or the fourth circuit layer M4 is disposed above the light shielding layer BM and overlaps the light shielding layer BM. From another perspective, the light shielding layer BM does not overlap the opening area 11, but surrounds the opening area 11 corresponding to the non-opening area 13. Therefore, in some embodiments, when the multi-layer circuit layer cannot clearly present the data line and / or the scanning line, the area surrounded by the light shielding layer BM can be defined as the opening area 11. In addition, the main bonding area 210 and the backup bonding area 220 can correspond to the overlapping light shielding layer BM. In this embodiment, the light shielding layer BM is, for example, a black matrix, and its material may include metal or a light-proof resin doped with a colorant, or other suitable materials or a combination of the above materials, but is not limited thereto. The above metal example may be chromium (Chromium, Cr), but is not limited thereto. The resin may be epoxy resin or acrylic resin, or other suitable materials or a combination of the above materials, but is not limited thereto. Under the above configuration, the contrast of the electronic device 10 may be increased.

[0033] It is worth noting that the circuit layer ML, the main bonding area 210 and the backup bonding area 220 of the electronic device 10 of an embodiment of the present disclosure can overlap the light shielding layer BM and be arranged in the non-opening area 13 outside the opening area 11, so that the unit PX of the electronic device 10 can have a high transmittance through the opening area 11. Thereby, the unit PX can be applied as a unit with a penetrating display function. In this way, the electronic device 10 has a good visual effect or display quality. In addition, the main bonding area 210 is used to bond electronic components, and the backup bonding area 220 includes an electronic component reserved space 320 for bonding repair or backup electronic components. Therefore, the unit PX of the electronic device 10 can reserve space and have a design for realizing a repair unit. In this way, the electronic device 10 has good electrical quality.

[0034] The following will be Figure 2 and Figure 3 The simple schematic diagram and simple circuit diagram shown are used to illustrate the steps and methods of unit repair.

[0035] Figure 2 It is a partial top view schematic diagram of an electronic device according to another embodiment of the present disclosure. Figure 3 for Figure 2 For the sake of clarity and convenience of explanation, Figure 2 and Figure 3 Some components are omitted from the illustration. Figure 2 , the electronic device 10A includes a unit PX. In some embodiments, the electronic device 10A also includes an opening area 11 and a non-opening area 13 surrounding the opening area 11. The light shielding layer BM overlaps the non-opening area 13 and surrounds the opening area 11. The unit PX includes a plurality of main bonding areas 210, 210', 210" and at least one backup bonding area 220. The plurality of main bonding areas 210, 210', 210" are arranged along the Y axis and overlap the non-opening area 13. At least one backup bonding area 220 is correspondingly disposed at one end of one of the main bonding areas (ex: the main bonding area 210) and overlaps the non-opening area 13. The main bonding area (ex: the main bonding area 210) and the backup bonding area 220 are respectively used to bond electronic components.

[0036] For example, the LED 300R is correspondingly bonded to the main bonding area 210, the LED 300B is correspondingly bonded to the main bonding area 210', and the LED 300G is correspondingly bonded to the main bonding area 210". That is to say, in the top-view direction (Z-axis direction), at least portions of the main bonding areas 210, 210', and 210" overlap with the LEDs 300R, 300G, and 300R, respectively. In addition, the backup bonding area 220 is adjacent to the main bonding area 210" where the LED 300G is disposed.

[0037] In this embodiment, the main junction area 210 is connected to the backup junction area 220. For example, please refer to Figure 2 and Figure 3 , the light emitting diode 300R, the light emitting diode 300G and the light emitting diode 300B are connected to the backup bonding area 220 through wires or bridge circuits. The electronic device 10A has pre-welding points WP, WP', WP" ( Figure 2 Only one pre-solder point WP is indicated) located between the backup joint area 220 and the main joint area 210, 210', 210" connected to the backup joint area 220. For example, a pre-solder point WP is provided between the main joint area 210 and the light-emitting diode 300R connected thereto and the backup joint area 220. A pre-solder point WP' is provided between the main joint area 210' and the light-emitting diode 300G connected thereto and the backup joint area 220. A pre-solder point WP' is provided between the main joint area 210" and the light-emitting diode 300B connected thereto and the backup joint area 220. In addition, the electronic device 10A further includes pre-cut points CP, CP', CP" located between the pre-solder points WP, WP', WP" and the main joint areas 210, 210', 210". For example, a pre-cut point CP is provided between the main joint area 210 and the light-emitting diode 300R connected thereto and the pre-solder point WP. A pre-cutting point CP' is provided between the main joining area 210' and the light-emitting diode 300G joined thereto and the pre-soldering point WP'. A pre-cutting point CP' is provided between the main joining area 210' and the light-emitting diode 300B joined thereto and the pre-soldering point WP'. Taking the light-emitting diode 300R as an example, under the above-mentioned setting, when the light-emitting diode 300R does not meet the inspection specifications (for example, including: dark spots, bright spots or appearance damage), a repair process of the electronic device 10A can be performed. The above-mentioned repair process includes: joining the electronic component for repair (for example, a red light-emitting diode) to the bonding pad of the electronic component reserved space 320 in the spare joining area 220; and then in the pre-cutting The laser cutting process is performed on the wire or bridge line at point CP; then the laser welding process is performed on the pre-welding point WP. After completing the above repair process, after providing a voltage to the electronic device 10A, the light-emitting diode 300R connected to the main bonding area 210 will not receive the voltage and will not emit light. The repair electronic component connected to the backup bonding area 220 can receive the above voltage and emit light. In this way, the electronic device 10A can complete the repair of the electronic component through the repair process, so the electronic device 10A can have good electrical quality.

[0038] It is worth noting that the number of the backup bonding areas 220 in the unit PX of the electronic device 10A of the present disclosure is less than the number of the main bonding areas 210, 210', 210". For example, Figure 2 and Figure 3The number of main bonding areas 210 shown is three, corresponding to the blue light-emitting diode 300B, the green light-emitting diode 300G and the red light-emitting diode 300R respectively. The number of backup bonding areas 220 is one, that is, the backup bonding area 220 can be correspondingly bonded to a repair electronic component (for example: a blue light-emitting diode, a green light-emitting diode, and a red light-emitting diode set in the electronic component reserved space 320), but the above-mentioned quantitative relationship is not used to limit the present disclosure. Under the above-mentioned setting, in the process of repairing the electronic device 10A, the repair electronic component can be selectively set in the reserved space. In this way, costs can be saved. In addition, since the reserved space can be reduced, the space for circuit setting can be increased, the requirements of high circuit density design can be met, or the transmittance of the opening area 11 can be improved. Thereby, the electronic device 10A can have good electrical quality.

[0039] Other embodiments will be listed below for illustration. It must be noted that the following embodiments use the component numbers and some contents of the previous embodiments, wherein the same numbers are used to represent the same or similar components, and the description of the same technical contents is omitted. The description of the omitted parts can be referred to the previous embodiments, and the following embodiments will not be repeated.

[0040] Figure 4 It is a partial top view schematic diagram of an electronic device according to yet another embodiment of the present disclosure. Figure 5 for Figure 4 For the sake of clarity and convenience of explanation, Figure 4 and Figure 5 Several components are omitted from the illustration. The electronic device 10B of this embodiment is substantially similar to Figure 2 and Figure 3Therefore, the same and similar components in the two embodiments are not repeated here. The main difference between this embodiment and the electronic device 10A is that the electronic device 10B includes a unit PX, an opening area 11 and a non-opening area 13 surrounding the opening area 11. The unit PX includes three main bonding areas 210, 210', and 210", and two backup bonding areas 220, 220'. For example, the backup bonding area 220 can be arranged adjacent to the main bonding area 210, and the backup bonding area 220' can be arranged adjacent to the main bonding area 210'. The pre-solder point WP is arranged corresponding to the backup bonding area 220. The pre-solder point WP is arranged corresponding to the backup bonding area 220'. The electronic component reserved space 320 in the backup bonding area 220 can be joined to the electronic component for repair. The electronic component reserved space 320' in the backup bonding area 220' can be joined to another electronic component for repair, but the above-mentioned quantitative relationship is not used to limit the present disclosure. In the present embodiment, the number of backup bonding areas 220, 220' is less than the number of main bonding areas 210, 210', and 210". Since the reserved space can be reduced, the space for line setting can be increased, the requirements of high circuit density design can be met, or the penetration rate of the opening area 11 can be improved. Thereby, the electronic device 10B can be repaired and have good electrical quality.

[0041] The following Figure 5 The circuit diagram shown briefly explains the steps and methods of unit repair.

[0042] Please refer to Figure 5 , the light-emitting diode 300R, the light-emitting diode 300G and the light-emitting diode 300B are connected to the backup bonding areas 220 and 220' respectively through wires or bridge lines. The electronic device 10B has pre-soldering points WP1, WP2, and WP3 located between the backup bonding area 220 or the backup bonding area 220' and the main bonding areas 210, 210', and 210". For example, the main bonding area 210 and the light-emitting diode 300R connected thereto and the backup bonding area 220 or the backup bonding area 220' have a pre-soldering point WP1. The main bonding area 210' and the light-emitting diode 300G connected thereto and the backup bonding area 220 or the backup bonding area 220' have a pre-soldering point WP2. The main bonding area 210' and the light-emitting diode 300B connected thereto and the backup bonding area 220 or the backup bonding area 220' have a pre-soldering point WP3. In addition, the electronic device 10B further includes pre-cut points CP1, CP2, CP3 located between the pre-welding points WP1, WP2, WP3 and the main bonding areas 210, 210', 210". For example, the main bonding area 210 and the light emitting diode 300R bonded thereto have a pre-cut point CP1 (between the pre-welding point WP1 and the pre-welding point WP2). Figure 4In the embodiment, the pre-cut point CP1 is disposed adjacent to the main bonding area 210). There is a pre-cut point CP2 (at Figure 4 The pre-cut point CP2 is disposed adjacent to the main bonding area 210'). There is a pre-cut point CP3 (at Figure 4 , the pre-cut point CP3 is disposed adjacent to the main bonding area 210″). Taking the LED 300R and the LED 300G as an example, under the above-mentioned setting, when the LED 300R and the LED 300G do not meet the inspection specifications (for example, including: dark spots, bright spots or appearance damage), the electronic device 10B can be repaired. The above-mentioned repair process includes: bonding the repair electronic component (for example, a red LED) to the bonding pad of the electronic component reserved space 320 in the backup bonding area 220; then bonding the repair electronic component (for example, a green LED) to the bonding pad of the electronic component reserved space 320′ in the backup bonding area 220′; then bonding the repair electronic component (for example, a green LED) to the bonding pad of the electronic component reserved space 320′ in the backup bonding area 220′; then bonding the repair electronic component (for example, a green LED) to the bonding pad of the electronic component reserved space 320′ in the backup bonding area 220′; and then bonding the repair electronic component (for example, a green LED) to the bonding pad of the electronic component reserved space 320′ in the backup bonding area 220′ at the pre-cut point CP3. 1, the wire or bridge circuit is subjected to a laser cutting process; then the wire or bridge circuit is subjected to a laser cutting process at the pre-cut point CP2; then the wire or bridge circuit is subjected to a laser cutting process at the pre-cut points CP5, CP7, and CP8; then the laser welding process is performed on the pre-welding points WP1 and WP2. After the above repair process is completed, after a voltage is provided to the electronic device 10B, the light emitting diode 300R joined in the main joining area 210 and the light emitting diode 300G joined in the main joining area 210' will not receive the voltage and will not emit light. The repair electronic components joined in the backup joining area 220 and the backup joining area 220' can receive the above voltage and emit light.

[0043] In some embodiments, please refer to Figure 5When the light-emitting diode 300B does not meet the inspection specifications (for example, including: dark spots, bright spots or appearance damage), and still does not meet the inspection specifications after the first repair is completed, the electronic device 10B can be repaired for the second time. For example, the electronic component for the first repair (for example, a blue light-emitting diode) is bonded to the bonding pad of the electronic component reserved space 320 in the backup bonding area 220; then the wire or bridge circuit is laser cut at the pre-cut point CP3; then the laser welding process is performed at the pre-welding point WP3, and then a voltage is provided to the electronic device 10B to test the light-emitting quality of the first repair electronic component. If it still does not meet the inspection specifications, a second repair process is performed, and the electronic component for the second repair (for example, a blue light-emitting diode) is bonded to the bonding pad of another electronic component reserved space 320' in another backup bonding area 220'; then the wire or bridge circuit is laser cut at the pre-cut points CP7, CP8, and CP9. After the above repair process is completed, a voltage is provided to the electronic device 10B again, and the LED 300B connected to the main bonding area 210" will not receive the voltage and will not emit light, while the repair electronic component connected to the backup bonding area 220' can receive the above voltage and emit light.

[0044] As a result, the electronic device 10B can complete the repair of the electronic components through the repair process, so the electronic device 10B can have good electrical quality.

[0045] It should be noted here that the above-mentioned repair process is only illustrated by taking LED 300R and LED 300G as electronic components that do not meet the inspection specifications. The definition of not meeting the inspection specifications may include: the electronic component emits light exceeding the preset average brightness (i.e., too bright), emits light below the preset average brightness (i.e., too dark), or does not emit light (i.e., not bright). Alternatively, the electronic component may be damaged, resulting in a defective appearance. In addition, the size of the electronic component is larger than the preset average size or smaller than the preset average size may also be deemed to be non-compliant with the inspection specifications, but the present embodiment is not limited to the above examples. In addition, LED 300R and LED 300B may also be electronic components that do not meet the inspection specifications. Alternatively, any one of LED 300R, LED 300G, or LED 300B may be an electronic component that does not meet the inspection specifications, and the present disclosure is not limited to this.

[0046] Figure 6 This is a partial top view of an electronic device according to another embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 6 Some components are omitted from the illustration. The electronic device 10C of this embodiment is substantially similar to Figure 4The electronic device 10B, therefore, the same and similar components in the two embodiments are not repeated here. The difference between this embodiment and the electronic device 10B is mainly that the electronic device 10C includes a unit PX, an opening area 11, and a non-opening area 13 surrounding the opening area 11. The electronic components respectively bonded to the main bonding areas 210, 210', and 210" in the unit PX are blue light-emitting diodes 300B. The electronic device 10C also includes a light conversion layer 340R or a light conversion layer 340G. The light conversion layer 340R overlaps the blue light-emitting diode 300B in the main bonding area 210. The light conversion layer 340G overlaps the blue light-emitting diode 300B in the main bonding area 210'.

[0047] For example, the light conversion layer 340R includes a quantum dot (QD) material that emits red light. The light conversion layer 340G includes a quantum dot material that emits green light. Under the above configuration, the blue light emitted by the blue light emitting diode 300B can be converted into red light by the light conversion layer 340R. Similarly, the blue light emitted by the blue light emitting diode 300B can be converted into green light by the light conversion layer 340G. In this way, the electronic device 10C can achieve the need to generate light of different colors by setting a blue light emitting diode 300B and matching quantum dot materials of different colors. In addition, the electronic device 10C can also achieve excellent technical effects similar to those of the above embodiments.

[0048] In summary, in an electronic device of an embodiment of the present disclosure, since the circuit layer, the main bonding area and the backup bonding area can overlap the light shielding layer and be arranged in a non-opening area outside the opening area, the unit of the electronic device can be a unit with a high transmittance through the opening area. In this way, the electronic device can be applied as a penetrating electronic device, or have a good visual effect or display quality. In addition, the main bonding area is connected to the backup bonding area to connect the electronic components for repair or backup through the backup bonding area. Therefore, the unit of the electronic device has a space reserved for setting the electronic components, and has a design for realizing the repair unit. In this way, the electronic device has good electrical quality. In addition, since the number of backup bonding areas can be less than the number of main bonding areas, the reserved space can be reduced to increase the layout of high-density circuits or improve the transmittance of the opening area, and the electronic components for repair can be selectively arranged in the reserved space. In this way, the electronic device can save costs, increase the space for circuit setting, meet the needs of high circuit density design or improve the transmittance of the opening area. Thereby, the electronic device can have good electrical quality.
