Problems solved by technology

However, in the prior art, even if the screen is turned off, once the touch screen is detected, it will enter the fingerprint identification process, and there is a problem of frequently waking up the system
In addition, all touches require the processor to perform the fingerprint recognition process, which results in higher system power consumption, shorter standby time, and poor user experience

Embodiment Construction

[0060] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0061] figure 1 It shows an electronic device 100 provided by an embodiment of the present invention, including: a touch screen 110 , a fingerprint module 120 , a main processor 130 and a coprocessor 140 .

[0062] The touch screen 110 can have a fingerprint detection area. More specifically, the effective detection range of the fingerprint module 120 can be at least partly located in the touch area of ​​the touch screen 110. Part of the touch area 110 is overlapped. Optionally, the area where the touch screen 110 covers the fingerprint module 120 can be used as the fingerprint detection area, but this is not limited in this embodiment of the present invention. A touch event on the fingerprint detection area can trigger a fingerprint identification process. Optionally, the fingerprint detection area ca...

Abstract

The invention discloses an electronic device and a detection method which are advantageous to reduce power consumption of electronic devices. The electronic device includes: a touch screen having a finger detection region, a fingerprint module, a main processor and a co-processor. The co-processor is intended for detecting a touch event on the touch screen. The fingerprint module is intended for acquiring touch data of the fingerprint detection region corresponding to the detected touch event. The co-processor is also intended for acquiring the touch data which is acquired by the fingerprint module, and determining whether the touch event occurs mistakenly.

Description

technical field [0001] The present application relates to the field of fingerprint identification, in particular to an electronic device and a detection method. Background technique [0002] For terminal devices with fingerprint identification function, if the fingerprint module itself does not have the function of finger detection, it is necessary to use the touch screen to detect whether there is a press on a specific area. If the touch screen detects a touch in the specified area, the fingerprint module will be started to collect fingerprints , and then enter the identification process, and the processor identifies the collected fingerprints. However, in the prior art, even if the screen is turned off, once the touch screen is detected, it enters the fingerprint identification process, and there is a problem of frequently waking up the system. In addition, all touches require the processor to execute the fingerprint identification process, which results in higher system ...
