Embodiment Construction

[0026] Below in conjunction with accompanying drawing and preferred embodiment the present invention is described in further detail:

[0027] Please refer to figure 1 , figure 1 It is a functional block diagram of the first embodiment of the fingerprint identification device of the present invention. The fingerprint identification device 100 can be set in an electronic device 200, especially a portable electronic device such as a mobile phone. The fingerprint identification device 100 is further integrated with a touch function. In this embodiment, the fingerprint identification device 100 includes a fingerprint identification element 110 , a capacitive touch element 120 and a controller 130 . The capacitive touch element 120 is used to continuously detect whether there is a touch object, such as a finger, touching the fingerprint identification device 100 . The fingerprint recognition element 110 is used for fingerprint recognition. The controller 130 is connected to the...

Abstract

A fingerprint recognition device comprises a capacitive touch control element, a fingerprint recognition element and a controller, wherein the capacitive touch control element is used for continuously detecting whether a touch control object touches the fingerprint recognition device; the fingerprint recognition element is used for carrying out fingerprint recognition; and the controller is connected with the fingerprint recognition element and the capacitive touch control element. When the capacitive touch control element detects a touch control object touches the fingerprint recognition device, the controller controls the capacitive touch control element to stop working and controls the fingerprint recognition element to start working. In the case of touch control operation, the fingerprint recognition element starts working, the capacitive touch control element stops working, the power consumption of the capacitive touch control element is smaller than that of the fingerprint recognition element, and thus, the power consumption of an electronic device is saved. The invention also provides a fingerprint recognition method.

Description

technical field [0001] The invention relates to a fingerprint recognition device and method. Background technique [0002] With the widespread use of portable electronic devices, users have put forward more functional requirements for portable electronic devices. Due to the privacy protection function, the fingerprint recognition sensor is installed in the portable electronic device to enhance user experience. Fingerprint identification devices can be divided into optical, capacitive, and acoustic wave types. Acoustic fingerprint recognition sensors are widely used because their operations are not easily affected by ambient temperature and humidity, and they have long life and high resolution. In order to respond quickly, the traditional acoustic wave fingerprint recognition sensor continuously generates and receives acoustic wave signals to sense whether there is a touch object, which consumes a lot of power. Contents of the invention [0003] In view of the above, it ...
