Touch equipment and method for performing fingerprint detection on touch equipment

Abstract

The invention discloses touch equipment and a method for performing fingerprint detection on the touch equipment. The touch equipment comprises a touch plane, a detection unit, a fingerprint module and a control module, wherein the touch plane is used for receiving touch of a user; the detection unit is fixed to the touch plane and used for detecting the touch of the user; the fingerprint module is fixed to the touch plane and used for collecting a fingerprint of the user; and after the detection unit detects that the user touches the touch plane, the control module starts a fingerprint collection function of the fingerprint module to collect the touch fingerprint of the user on the touch plane. According to the touch equipment and the method, after it is detected that the user touches the touch plane, starting of the fingerprint collection function of the fingerprint module is triggered to collect the touch fingerprint of the user on the touch plane, the user only needs to perform one time of touch operation in the whole process, meanwhile, the fingerprint module is not started unless the fingerprint of the user touches the touch plane, and therefore the problem that power consumption is excessively high when the fingerprint module is started for a long time is avoided.

Description

[0001] This application refers to the Chinese patent application No. 2015107291248 entitled "Touch Device and Fingerprint Detection Method on Touch Device" submitted on October 30, 2015, which is incorporated by reference in its entirety into this application. technical field [0002] The invention relates to the field of touch control, in particular to a touch control device and a method for detecting fingerprints on the touch control device. Background technique [0003] Fingerprint recognition technology has been widely used in mobile smart devices. Taking smart phones as an example, fingerprint recognition has become the mainstream configuration. While providing security, push-type fingerprint recognition has gradually occupied the mobile smart device market due to its high recognition rate and small size. At present, the push-type fingerprint recognition chip exists as an independent module, which is applied to the physical button on the front of the device, or installe...

AI Technical Summary

Problems solved by technology

[0007] 1. High power consumption: The overall area of ​​the touch screen or touchpad is dozens of times that of the independent fingerprint module, which means that the fingerprint module and the flat integrated device need more pixels to participate in finger touch detection, and the power consumption becomes larger , unable to achieve low power consumption and long-term standby detection

[0008] 2. Low recognition: based on a small number of pixels of capacitive sensing detection finger touch to achieve cold screen wake-up, different people's finger pressure sensing is different, and the fault tolerance of waterproof and false triggering is not enough

Putting mobile smart devices in pockets or getting water on the screen will easily lead to false triggers

Long-term errors will affect user experience and increase overall power consumption
