Moving fingerprint recognition method and apparatus using display
Abstract:
Moving fingerprint recognition method and apparatus using display is provided. A moving fingerprint recognition method includes driving a pixel array, a touch sensor and a fingerprint sensor located in a display area of a display, continuously sensing touch positions of a finger touching and moving on a surface of the display through the fingerprint sensor, calculating touch coordinates of each frame from an output of the touch sensor during a time corresponding to a plurality of frames, and storing the touch coordinates in a memory, continuously sensing a fingerprint of the touched and moved finger through the fingerprint sensor, acquiring fingerprint data of each frame from an output of the fingerprint sensor during the time corresponding to the plurality of frames, and storing the fingerprint data in the memory, and acquiring fingerprint recognition data of one frame by up-scaling, summing and synthesizing the fingerprint data of the plurality of frames.
