Abstract: An electronic device includes a keyboard. The keyboard includes a base plate and keys disposed on a base plate. The base plate includes a back support plate, a membrane, and a backlight plate. The membrane and the backlight plate are disposed on two sides of the back support plate. The back support plate supports the membrane, the backlight plate, and the keys. In addition, a buffer structure is disposed on a surface of a side that is of the backlight plate and that faces the key. The back support plate is provided with a first through hole. The key is disposed on a side that is of the membrane and that is away from the back support plate. A protrusion is disposed on a side that is of the key and that faces the base plate. The key moves toward the base plate. The protrusion can press the buffer structure.

Abstract: A keyboard includes a bottom plate, a circuit board disposed on the bottom plate, and a plurality of keys disposed on a side that is of the circuit board and that is away from the bottom plate. Each key includes a keycap, a rise-and-fall component connecting the keycap to the bottom plate, and an electronic ink screen fastened on a side that is of the keycap and that is away from the rise-and-fall component. A first electric conductor connected to the electronic ink screen is disposed on the keycap, a second electric conductor is disposed on the rise-and-fall component, and a third electric conductor is disposed on the bottom plate. A signal line used to supply power to the electronic ink screen is disposed on the circuit board.
