  • Patent number: 11887791
    Abstract: A key module includes a bottom plate, a circuit layer, a key cap, a supporting structure, a touch member, and a flexible circuit board. The bottom plate has a first surface and a second surface opposite to each other. The circuit layer is disposed on the first surface and has a first opening. The key cap is disposed above the circuit layer and covers the first opening. The supporting structure is disposed between the bottom plate and the key cap. The touch member is disposed at the key cap. The flexible circuit board is electrically connected to the touch member and passes through the first opening to extend next to the second surface of the bottom plate. When the key cap moves downward relative to the bottom plate, a portion of the flexible circuit board located between the key cap and the bottom plate is bent.

  • Publication number: 20150380603
    Abstract: A light-emitting element substrate and a light-emitting element using the same are disclosed. The light-emitting element substrate includes a transparent substrate and an intermediate layer. The transparent substrate has a plurality of microstructures on a surface thereof, top portion of each microstructure is a plane structure, and an adjacent interval between the plane structures is between 0.5 ?m and 2.5 ?m, the plurality of microstructures have gaps therebetween, and the intermediate layer is covered on the plane structures for facilitating production of epitaxial layer. In an embodiment, the gaps of the plurality of microstructures are still reserved when the epitaxial layer is grown on the plurality of microstructures so as to improve light extraction efficiency of the light-emitting element using the light-emitting element substrate.
