The present invention discloses a fingerprint recognition element comprising: a plurality of parallel fingerprint detecting electrodes, the distance between two adjacent fingerprint detecting electrodes being not larger than the distance between adjacent ridge and valley in the fingerprint, a fingerprint recognition signal being loaded to one end of each fingerprint detecting electrode, and the fingerprint recognition signal being acquired in real time at the other end of each fingerprint detecting electrode. When a user finger approaches the display screen, since there are uneven ridges and valleys on the surface of the skin of the finger, the distances between respective points on the skin surface and the respective fingerprint detecting electrodes are also different, thereby influencing the capacitance value of the respective fingerprint detecting electrodes. By detecting the differences of the signals acquired from respective fingerprint detecting electrodes at each moment in the process of touching the display screen by the finger, a two-dimensional pattern of the fingerprint can be detected, so as to realize fingerprint recognition. The present invention further discloses a display screen comprising the fingerprint recognition element and a display device comprising the display screen.
