Patent ID: 11928885
Assignee: SHENZHEN GOODIX TECHNOLOGY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 7:
8. A fingerprint identification apparatus, wherein the fingerprint identification apparatus is disposed under a display screen of an electronic device for under-screen fingerprint identification, and the fingerprint identification apparatus comprises:
a pixel array configured to capture 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; and
a colour filter layer comprising at least one filter unit, the at least one filter unit being disposed above at least one first type pixel of the pixel array, respectively;
wherein the at least one first type pixel is configured to sense a first light signal transmitting through the at least one filter unit, and an intensity of the first light signal is used for determining a fingerprint identification environment to obtain a target capturing parameter of capturing the fingerprint light signal;
wherein the fingerprint identification apparatus further comprises a processor, and the processor is configured to:
determine the fingerprint identification environment based on the intensity of the first light signal; and
determine the target capturing parameter based on the fingerprint identification environment;
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 processor is configured to:
determine 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
determine 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.
