Fingerprint identification apparatus and electronic device
A fingerprint identification apparatus and an electronic device. The fingerprint identification apparatus includes: a fingerprint sensor; and the fingerprint sensor including an optical sensing array, wherein a spatial period N of the optical sensing array satisfies N<M/2K; wherein M is a spatial period of a light-emitting pixel array, and K is a zoom ratio between an image displayed in a sensing area of the fingerprint sensor and an image captured in the sensing area by the fingerprint sensor. By clarifying the relationship between the spatial period of the light-emitting pixel array in the display screen and the spatial period of the optical sensing array in the fingerprint sensor, it can avoid the sensor from generating moiré fringes when imaging based on light received by transmitting through the display screen, thereby improving fingerprint identification performance.
