Electronic device with edge wire and protection layers
A recently granted patent (Publication Number: US11923491B2) discloses an electronic device with unique features. The device includes a substrate with a first surface, a second surface, and a side surface connecting the two, where an edge wire extends from the first surface to the second surface through the side surface. A first protection layer sandwiches the edge wire between the substrate and itself, forming an undercut structure, which is then filled by a second protection layer. The edge wire is retracted relative to the second protection layer, and the second protection layer surrounds the first protection layer, with the undercut structure distributed along the edge wire's periphery.
Furthermore, the electronic device also incorporates a driving circuit structure connected to the edge wire and a light-emitting element. The driving circuit structure includes pads on the first and second surfaces, with the edge wire connected to both. Another embodiment of the device features a protection structure wrapping around the edge wire, creating an interstice between the two. This interstice, whether closed or distributed along the edge wire's periphery, helps maintain a distance between the edge wire and the protection structure, ensuring optimal functionality of the electronic device.
