Abstract

The embodiment of the invention discloses a biometrics sensing device and method and an information device provided with the biometrics sensing device. The biometrics sensing device comprises a biometrics sensing area in which a plurality of sensing units are provided; a control circuit, coupled to the plurality of sensing units, the control circuit operating in a first energy dissipation state drives at least one of the plurality of sensing units to sense, and switching to a second energy dissipation state when a biometric object is sensed to approach or contact the biometric sensing region;the control circuit in the second energy dissipation state drives the plurality of sensing units to sense the biometric characteristics of the biometric body, wherein the energy dissipation power of the second energy dissipation state is greater than the energy dissipation power of the first energy dissipation state.

Description

technical field [0001] The present invention relates to a biometric sensing device and method and an information device provided with the biometric sensing device, in particular to a biometric sensing device and method with a power saving function and an information device provided with the biometric sensing device. Background technique [0002] Fingerprint recognition is already a very important application on portable devices (such as smart phones), and it mainly plays the role of user identity authentication. Especially in today's mobile payment that is becoming more and more popular, it has become an indispensable component on portable devices. It can be observed from the current application that the fingerprint identification module on the portable device does not care much about power saving, because its power consumption is very small compared to other components on the portable device. However, as more and more applications in the field of the Internet of Things (IOT...
