Claim 0:
1. A fingerprint identification method, wherein the method is applied to a fingerprint identification apparatus disposed under a display screen of an electronic device, the fingerprint identification apparatus comprises a pixel array and a colour filter layer, the colour filter layer comprises at least one filter unit, and the at least one filter unit is disposed above at least one first type pixel of the pixel array, respectively, and the method comprises:
capturing a first light signal transmitting through the at least one filter unit and sensed by the first type pixel;
determining a fingerprint identification environment according to an intensity of the first light signal; and
determining, based on the fingerprint identification environment, a target capturing parameter of capturing a fingerprint light signal returned by reflection or scattering of a finger above the display screen, the fingerprint light signal being used for fingerprint identification;
wherein the at least one filter unit comprises at least one red filter unit, the red filter unit is configured to transmit through a red light signal, and the first light signal comprises the red light signal; and
the determining the fingerprint identification environment according to the intensity of the first light signal comprises:
determining that the fingerprint identification environment is a strong light environment when an intensity of the red light signal is greater than a preset red light signal intensity; or
determining that the fingerprint identification environment is a normal environment when an intensity of the red light signal is less than or equal to a preset red light signal intensity.
