Abstract
A keyboard with backlighting functionality includes: a membrane circuit substrate; a press key set having a plurality of press keys that are disposed on the membrane circuit substrate, and that are capable of being pressed so as to cause the membrane circuit substrate to transmit input signals; and at least one light-emitting element disposed near an edge of the membrane circuit substrate. The membrane circuit substrate is configured as a backlighting sheet that allows light from the light-emitting element to propagate therein, and is formed with an internal structure that is able to direct the light that propagates in the membrane circuit substrate toward the press keys of the press key set.
