Touch device and method for performing fingerprint detection on touch device

Abstract

The present invention discloses a touch device and a method for performing fingerprint detection on the touch device. The touch device comprises: a touch plane used for receiving touch of a user; a detection unit that is fixed together with the touch plane and used for detecting the touch of the user; a fingerprint module that is fixed together with the touch plane and used for collecting a fingerprint of the user; and a control module, that, when the detection unit detects that the user touches the touch plane, enables a fingerprint collection function of the fingerprint module to collect the fingerprint, touching the touch plane, of the user. According to the method, when it is detected that the user touches the touch plane, the fingerprint collection function of the fingerprint module is enabled by triggering to collect the fingerprint, touching the touch plane, of the user; the user only needs to perform a touch operation once in the whole process; and, the fingerprint module is enabled only when the finger of the user touches the touch plane, thereby avoiding the problem of excessive power consumption caused by long-time operation of the fingerprint module.

Description

technical field [0001] 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 [0002] 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 installed independently on the device shell. With the development of fingerprint recognition technology, mobile smart devices require more and more screen space and screen ratio, and require a more humanized unlocking experience under the same high security level.

AI Technical Summary

Problems solved by technology

[0006] 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

[0007] 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
