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.
