A device may include a display portion that includes a display housing and a display at least partially within the display housing. The device may also include a base portion pivotally coupled to the display portion and including a bottom case, a top case coupled to the bottom case and defining an array of raised key regions, and a sensing system below the top case and configured to detect an input applied to a raised key region of the array of raised key regions.

A keyboard includes a base plate, a membrane circuit board, a backlight module, and a plurality of keyswitch assemblies. The base plate has a plurality of through holes. The membrane circuit board is disposed on the base plate. The backlight module is disposed at a side of the base plate away from the membrane circuit board and configured to emit light toward the base plate. The keyswitch assemblies are disposed on the membrane circuit board. Each of the keyswitch assemblies includes a position-returning member located over one of the through holes. An orthogonal projection of the position-returning member projected on the base plate overlaps a part of said one of the through holes.

A pressure-activated membrane switch and methods of use are provided. The pressure-activated membrane switch includes an electrically-conductive membrane, and a compliant conductive material having an electrically-conductive inner surface, wherein contact between the electrically-conductive membrane and the electrically-conductive inner surface of the compliant material is configured to cause an electrical circuit, of which the switch is a part, to close. The pressure-activated membrane switch further includes a plurality of spacers dispersed between the electrically-conductive membrane and the compliant conductive material. The plurality of spacers form one or more gaps between the electrically-conductive membrane and the compliant conductive material, and, with an application of pressure against the compliant conductive material, the compliant conductive material is configured to deform between the one or more gaps to contact the electrically-conductive membrane.

A luminous keyboard includes at least one key, a switch circuit board, a supporting plate, a backlight module, a reflecting plate and a light-sheltering plate. The backlight module emits a light beam. The backlight module is arranged between the reflecting plate and the light-sheltering plate. A periphery region of the reflecting plate and a periphery region of the light-sheltering plate are thermally laminated or laser welded to define a sealed structure. Since the periphery region of the backlight module is sealed by the sealed structure, the light beam is not leaked out through the periphery region of the backlight module. The space occupied by the sealed structure is not very large. Consequently, the volume of the luminous keyboard is reduced.

A device may include a display portion that includes a display housing and a display at least partially within the display housing. The device may also include a base portion pivotally coupled to the display portion and including a bottom case, a top case coupled to the bottom case and defining an array of raised key regions, and a sensing system below the top case and configured to detect an input applied to a raised key region of the array of raised key regions.

There is provided a keyboard cover including a first sheet material having a surface including a plurality of key tops configured of roughened surfaces and a base configured of a smooth surface connecting a plurality of the key tops, a plurality of the key tops being projected from the base viewed from the surface; and a second sheet material covering a rear surface of the first sheet material and having concave parts corresponding to a plurality of the key tops viewed from the rear surface. Also provided is an electronic apparatus, including a keyboard body and the keyboard cover.
