Abstract: A keyboard device includes a base plate, a plurality of key structures, a floating frame and a cover layer. The key structures are disposed over the base plate, and each of the key structures has a keycap. The floating frame is disposed over and separated from the base plate. The floating frame has a plurality of openings, and the key structures are disposed in the openings, respectively. The cover layer covers the keycaps of the key structures and the floating frame and is in direct or indirect contact with an upper surface of the keycap of each of the key structures and an upper surface of the floating frame. When the keycap of one of the key structures and the cover layer thereover are pressed to bottom, the floating frame surrounding the one of the key structures is pulled by the cover layer and shifted.

Abstract: A covering structure includes at least one element, a gas impermeable film and an adhesive layer. The gas impermeable film covers the at least one element. The adhesive layer is adhered between the at least one element and the gas impermeable film, and the adhesive layer has a perforation pattern, a perforation repair pattern, or a combination thereof. A method of forming a covering structure is also provided, which includes: making a surface of an adhesive layer with a perforation pattern facing one of at least one element and a gas impermeable film to form a first structure; performing a first gas suction treatment on the first structure; making another surface of the adhesive layer of the first structure facing the other thereof to form a second structure; and performing a second gas suction treatment on the second structure.
