Abstract:
An illuminated keyboard includes a membrane circuit board, a base plate, a key structure, a backlight module and a first reflective layer. The base plate is disposed beneath the membrane circuit board and has a first through hole and a plurality of second through holes adjacent to the first through hole. The key structure is disposed over the membrane circuit board and includes an elastic member. The backlight module is disposed beneath the base plate. The backlight module includes: a direct-type light-emitting element, substantially aligned with the first through hole and misaligned with a trigger portion of the elastic member; and a light guide plate, laterally adjacent to the direct-type light-emitting element. The first reflective layer is disposed over, beneath, or over and beneath the membrane circuit board and is substantially aligned with the first through hole.
