Abstract

A display device includes a cover plate, an OLED display substrate and a photosensitive sensor. A color filter layer is arranged between the cover plate and the OLED display substrate and includes a light-shielding region arranged between adjacent color resistance layers. A plurality of imaging pinholes is formed in the light-shielding region and a first distance between the cover plate and each imaging pinhole is smaller than a second distance between the photosensitive sensor and the imaging pinhole. A fingerprint identification method for the display device includes: dividing the plurality of imaging pinholes into at least two groups of imaging pinholes; imaging the fingerprint via the at least two groups of imaging pinholes sequentially in accordance with a predetermined time sequence, to acquire at least two first fingerprint images; and combining the at least two first fingerprint images to acquire a complete fingerprint image.
