Specifically, in the present embodiment, a portion of the adjacent bridge members130amay be connected to the connecting lines120aand the redundancy connecting lines122at the same time, wherein the redundancy connecting lines122are not overlapped with the connecting lines120ain the normal direction (the third direction D3) of the support substrate110. For example, the redundancy connecting lines122may be further disposed between the bridge members130a2and the bridge members130a3, for example, and the redundancy connecting lines122are not overlapped with the connecting lines120a(the connecting lines120a1) between the bridge members130a2and the bridge members130a3in the normal direction of the support substrate110. If the connecting lines120a1located between the bridge members130a2and the bridge members130a3are broken, at least signal transmission may still be implemented via the redundancy connecting lines122to reduce the failure of the electronic device10adue to inability to transmit signals. However, althoughFIG.4shows that the redundancy connecting lines122are disposed between the bridge members130a2and the bridge members130a3, the disclosure is not limited thereto. That is, the redundancy connecting lines122may also be disposed between other adjacent bridge members130a.

Viewed from another perspective, in some embodiments, the support plate100bincludes the redundancy connecting lines122. The redundancy connecting lines122may be connected to the bridge members130a2(second bridge members) and the bridge members130a3(fifth bridge members). In addition, the redundancy connecting lines122are not overlapped with the signal lines CL in the third direction D3(normal direction) of the substrate210, for example.

It should be noted that, the embodiment ofFIG.5may adopt the reference numerals and part of the content of the embodiment ofFIG.2C. The same or similar reference numerals are used to indicate the same or similar components, and the description of the same technical content is omitted.

Referring toFIG.2AandFIG.5at the same time, the main difference between an electronic device10dof the present embodiment and the electronic device10ais: the electronic device10dfurther includes an insulating layer IL disposed between the metal layer M1and the metal layer M2of the connecting lines120a, a portion of the metal layer M2is electrically connected to the metal layer M1through the insulating layer IL, and this design may reduce the chance of failure due to inability to transmit signals. In some other embodiments, the insulating layer IL is between the metal layer M1and the metal layer M2and electrically isolates the metal layer M1and the metal layer M2, the insulating layer IL may be configured to reduce the configuration area of the metal layer M1and the metal layer M2, and make the metal layer M1and the metal layer M2transmit different electrical signals, respectively. For example, the metal layer M1may be configured to transmit a power signal, and the metal layer M2may be configured to transmit a data signal, but the disclosure is not limited thereto.

FIG.6Ais a schematic top view of an electronic device of the second embodiment of the disclosure, andFIG.6Bis an exploded view according toFIG.6A. It should be noted that, the embodiment ofFIG.6AandFIG.6Bmay respectively adopt the reference numerals and part of the content of the embodiment ofFIG.2AandFIG.2B. The same or similar reference numerals are used to indicate the same or similar components, and the description of the same technical content is omitted.

Referring toFIG.6AandFIG.6Bat the same time, the main difference between an electronic device20of the present embodiment and the electronic device10ais: a support plate100cof the electronic device20further includes a plurality of connecting lines140and a plurality of bridge members150, and a panel200bof the electronic device20further includes a gate driving circuit400, a working signal line410, a working connecting line420, and a plurality of bridge members430.

In some embodiments, the plurality of connecting lines140are located in the peripheral area PA and substantially extended along the first direction D1. In some embodiments, a portion of the connecting lines140are electrically connected to the second circuit board CB2in the circuit board CB, and the plurality of connecting lines140are spaced apart from each other in the first direction D1. In detail, a portion of the connecting lines140are connected to the second circuit board CB2in the fan-out area FA, for example, and are disposed at intervals along the first direction D1in the peripheral area PA. The plurality of bridge members150are, for example, disposed on the support substrate110and electrically connected to the corresponding connecting lines140. In some embodiments, the plurality of bridge members150may be disposed on each of the connecting lines140along the first direction D1and spaced apart from each other, so that the corresponding connecting line140may be configured to electrically connect adjacent panels200bto each other, which will be explained in detail in the following embodiments. In some embodiments, for the connecting lines140, the width in the second direction D2, the thickness in the third direction D3, the material included, and the composition structure may be the same as or similar to the connecting lines120aof the above embodiments, and details are not repeated herein.

In some embodiments, the distance between adjacent bridge members150may be greater than or equal to 2 mm and less than or equal to 30 mm. For example, the distance between adjacent bridge members150may be 2.5 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, or 28 mm, but the disclosure is not limited thereto.

The gate driving circuit400is disposed in the display area AA, for example. In the present embodiment, the gate driving circuit400includes a gate driving circuit (gate driver on panel, GOP) disposed on the panel, but the disclosure is not limited thereto. The gate driving circuit400may be connected to the working connecting line420, and the working connecting line420may be connected to the working signal line410, so that the gate driving circuit400may be driven via the working signal line410, wherein the working signal line410is extended along the first direction D1, and the working connecting line420is extended along the second direction D2. In some embodiments, the working signal line410is electrically connected to the second circuit board CB2via the plurality of bridge members430, the connecting lines140, and the plurality of bridge members150, but the disclosure is not limited thereto. Specifically, the plurality of bridge members430, for example, penetrate through the substrate210and are electrically connected to the working signal line410, so that the corresponding bridge members430may be connected to the corresponding bridge members150. As a result, an electrical signal transmission path formed by the connecting lines140, the bridge members150, the bridge members430, the working signal line410, the working connecting line420, and the gate driving circuit40is created. In some embodiments, each of the plurality of bridge members430corresponds to the plurality of bridge members150disposed on the support substrate110, that is, the bridge members150may be, for example, at least partially overlapped and electrically connected to the corresponding bridge members430. Moreover, in some embodiments, the plurality of working signal lines410may also be disposed spaced apart from each other in the first direction D1, and may be overlapped with the connecting lines140disposed on the support substrate110, but the disclosure is not limited thereto.

Since the plurality of bridge members430on the panels200beach correspond to the plurality of bridge members150disposed on the support substrate110, in some embodiments, the distance between adjacent bridge members430may also be greater than or equal to 2 mm and less than or equal to 30 mm. For example, the distance between adjacent bridge members430may be 2.5 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, or 28 mm, but the disclosure is not limited thereto.

It should be mentioned that, although two bridge members430electrically connected to one working signal line410on one panel200bare shown in the present embodiment, the disclosure is not limited thereto. That is, in other embodiments, the number of the plurality of bridge members430electrically connected to one working signal line410may be more than two.

FIG.7is a schematic top view of an electronic device of some embodiments of the disclosure. It should be noted that, the embodiment ofFIG.7may adopt the reference numerals and part of the content of the embodiments ofFIG.1andFIG.2A. The same or similar reference numerals are used to indicate the same or similar components, and the description of the same technical content is omitted.

Referring toFIG.7, the main differences between an electronic device30of the present embodiment and the electronic device10aare: the electronic device30further includes a plurality of test pads160, a plurality of test connecting lines170, and a plurality of test bridge members180disposed in the peripheral area PA. The plurality of test pads160may be disposed in the peripheral area PA on the support substrate110, and the plurality of test connecting lines170may be disposed on the support substrate110. In some embodiments, one of the plurality of test connecting lines170is extended substantially along the first direction D1and connected to the corresponding test pad160. The plurality of test bridge members180are, for example, disposed in the display area AA on the support substrate110. In some other embodiments, at least a portion of the plurality of test bridge members180may be disposed in the peripheral area PA (not shown) on the support substrate110. In some embodiments, one of the plurality of test bridge members180is electrically connected to the corresponding test connecting line170. In addition, the plurality of test bridge members180may be disposed on each of the test connecting lines170along the first direction D1and spaced apart from each other, but the disclosure is not limited thereto. Accordingly, when whether the signal transmission to the electronic device30is normal needs to be detected, the probes of a test device (not shown) may be electrically connected to the corresponding test pads160, for example, in order to measure the signal transmitted on the corresponding test connecting lines170and test bridge members180. Accordingly, in some embodiments, according to the signal information transmitted on the test connecting lines170obtained by the test device, the location of failure of the electronic device30may be further determined.

Based on the above, the electronic device provided by some embodiments of the disclosure includes a support plate and a plurality of panels disposed thereon, wherein the support plate includes a plurality of connecting lines extended along a specific direction and spaced bridge members electrically connected to one connecting line, and there is a plurality of bridge members of the support plate corresponding to the corresponding bridge members disposed on each panel. Accordingly, in a subsequent process or during use of the electronic device of an embodiment of the disclosure, when some of the connecting lines are broken due to reasons such as bending of the electronic device, or some of the bridge members of the support plate and/or the bridge members of the panel are defective and may not be electrically connected, additional signal transmission paths may be created by the arrangement of the plurality of connecting lines and/or the arrangement of the plurality of bridge members of the support plate and the bridge members of the panel. In this way, the failure of the electronic device of an embodiment of the disclosure due to inability to transmit signals may be reduced. Moreover, in the electronic device provided by some other embodiments of the disclosure, a redundancy connecting line electrically connected to a plurality of (e.g., two) bridge members of the support plate at the same time is also provided. When the connecting line located between the plurality of bridge members of the support plate is broken, signal transmission may still be implemented via another additional path provided by the redundancy connecting line, so as to reduce the failure of the electronic device of an embodiment of the disclosure due to the inability to transmit signals.
