Abstract

See full text

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.
