摘要:
The present invention discloses a method for logging in to a terminal based on fingerprint identification in a standby state. The method includes the following steps: a fingerprint scanning and identification step: in the standby state, scanning and identifying fingerprint information input by a user; an awaking step: if the fingerprint information is successfully identified, awaking a control chip, and sending acknowledgement information indicative of successful fingerprint identification to the control chip; and an unlocking step: upon receiving the acknowledgement information indicative of successful fingerprint identification, unlocking, by the control chip, the terminal, such that the user successfully logs in to the terminal. With the fingerprint identification technology according to the present invention, even in a standby state, the fingerprint scanning and detection function may still be enabled; and once an input fingerprint is scanned, identification and awake actions may be triggered, thereby saving manual awaking before the scanning and identification function is enabled. In this way, user experience is improved.

The present invention discloses a fingerprint detection apparatus and a mobile terminal. The fingerprint detection apparatus comprises a capacitive fingerprint sensor and a capacitive touch control chip which is electrically connected to the capacitive fingerprint sensor; wherein the capacitive fingerprint sensor is configured to collect fingerprint information and convert the fingerprint information to an analog signal; and the capacitive touch control chip is configured to convert the analog signal to a digital signal, and generate fingerprint image information according to the digital signal. As compared with the dedicated control chip in the related art, the capacitive touch control chip has mature design and manufacture technique, and thus the manufacture and application costs are lower. Particularly when the fingerprint detection apparatus is applied in a capacitive touch control terminal, the capacitive touch control chip of the capacitive touch control terminal may be used to achieve detection and identification of the fingerprint, which significantly improves the technical integration and reduces the application cost.
