Abstract
The present disclosure provides a display device and a fingerprint identification method thereof, which belong to the field of fingerprint identification technology and can solve the existing problems of complex reflective light path in the process of fingerprint identification, large noise in the sensed signal and low accuracy of fingerprint identification. The display device in which the fingerprint identification method of a display device of the present disclosure is applicable comprises a plurality of pixel units for display, and a plurality of light sensing units for generating a sensed signal based on intensity of received light; the fingerprint identification method comprises: enabling part of the pixel units to emit light and keeping other pixel units not to emit light, and performing fingerprint identification based on the sensed signal generated by the plurality of light sensing units.
