摘要： A method for identifying a fingerprint, a fingerprint identification apparatus and an electronic device are provided. The method includes: acquiring light signals in multiple directions reflected via a sampled object above a display screen; generating a plurality of two-dimensional 2D fingerprint images respectively based on the light signals; determining whether the sampled object is a three-dimensional 3D object based on the plurality of 2D fingerprint images; and if the sampled object is the 3D object, performing fingerprint identification based on at least one of the plurality of 2D fingerprint images. A distinction between a 2D object and a 3D object is effectively achieved through the light signals in the multiple directions, and when the sampled object is a 3D object, subsequent fingerprint identification is performed, which fundamentally avoids performing the fingerprint identification based on a fake fingerprint captured by a 2D object, thereby improving security of the fingerprint identification.

摘要： A method for determining a change of an initial distance of a sensing electrode is provided. The method includes: calculating a real-time pressure output by each sensing electrode according to real-time feature data output by each sensing electrode in a touch screen when a pressure is applied on the touch screen and a corresponding relationship between the feature data and the pressure; rectifying the real-time pressure output by each sensing electrode according to prestored relative elastic coefficients at different press positions relative to each sensing electrode; and determining a sensing electrode whose initial distance is changed among all the sensing electrodes according to a difference between the rectified real-time pressures output by different sensing electrodes, to calibrate the corresponding relationship between the feature data and the pressures of the sensing electrode whose initial distance is changed.
