A method for capacitive fingerprint identification. The method is applied to an electronic device with a capacitive fingerprint identification apparatus which has a special-shaped surface. The method includes: obtaining a number of driving signals N(i) of an icolumn of pixel electrodes; and performing signal driving to the icolumn of pixel electrodes to obtain an output voltage according to the number of driving signals N(i), the output voltage corresponds to the capacitor, and the output voltage is configured for fingerprint identification. The present application can controls a column average output voltage of the pixel electrode at a similar level, so as to facilitate algorithmic processing, at the same time, a risk of data saturation with up and down fluctuations is reduced, and thereby the performance of fingerprint identification is improved.

Disclosed are near-field communication system, method and terminal. The near-field communication system includes a first terminal and a second terminal configured to: when it is detected that a coupling capacitance between the first terminal and the second terminal is less than a predetermined value, adjust a connection of a driving channel and/or a sensing channel of the second terminal, to adjust the coupling capacitance between the second terminal and the first terminal; and establish communication between the second terminal and the first terminal when it is detected that the coupling capacitance between the first terminal and the second terminal is greater than or equal to the predetermined value.
