Abstract

See full text

A pressure sensitive and luminous keyboard includes at least one key, a pressure detecting circuit, an illumination module and a controlling unit. When one of the plural keys is depressed in response to a first pressure, the pressure detecting circuit generates a pressure-strength sensing voltage. According to the pressure-strength sensing voltage, the controlling unit will judge the strength of the first pressure and control the illumination module to emit either the first light beam or the second light beam.
