Abstract: A luminous keyboard includes a keypad module, plural light-emitting elements, a light guide plate and a reflecting plate. The reflecting plate has plural light amount control structures. The light amount control structures are disposed on the reflecting plate, and located near the corresponding light-emitting elements. When the plural light-emitting elements emit light beams, the portions of the light beams that are not subjected to total internal reflection within the light guide plate are reflected by the reflecting plate. When the light beams are transferred through the light amount control structure, the reflected fraction of the light beams is reduced. Since the light beams are not very centralized, the problem of generating bright spots will be diminished.

Abstract: A keyboard includes a base plate, a pressure sensing layer, a first key structure and a second key structure. The pressure sensing layer includes plural pressure sensing regions. Each of the first key structure and the second key structure corresponds to a pressure sensing region. Moreover, the first key structure and the second key structure are located over the corresponding pressure sensing regions. In response to different magnitudes of the depressing force, the corresponding pressure sensing regions are pushed by the first key structure and the second key structure. Consequently, the corresponding pressure sensing regions generate different pressure sensing signals. The pressure sensing layer can replace plural pressure sensing element. Consequently, the assembling process is simplified, and the assembling cost is reduced.
