Title: OPTICAL FINGERPRINT SENSOR MODULE
Abstract:
An optical fingerprint sensor module, comprising: an optical fingerprint sensor, the optical fingerprint sensor comprising pixel areas in which photosensitive pixels are located; the photosensitive pixels comprise optical fingerprint sensing elements, a light transmissive area, and a light non-transmissive area, the optical fingerprint sensing elements being positioned in the light non-transmissive area; all of the optical fingerprint sensing elements are arranged in rows; a dot backlight source, each pixel area corresponding to one dot backlight source; the dot backlight sources being arranged diagonally below the outermost row of photosensitive fingerprint sensing elements corresponding to the pixel area; in a pixel area, selecting the largest square area having a centre point closest to the dot backlight source; dividing the photosensitive fingerprint sensing elements in the largest square area into different element groups, and arranging the photosensitive fingerprint sensing elements in different element groups differently. The performance of the optical fingerprint sensor module is improved.
