Title: OPTICAL FINGERPRINT SENSOR MODULE
Abstract:
An optical fingerprint sensor module. The optical fingerprint sensor module comprises: a backlight source (210); an optical fingerprint sensor (220) that comprises a first surface, a second surface, a first light-transmissive region, and a photosensitive pixel (2221); and an OLED display panel (230) that comprises a third surface, a fourth surface, and a second light-transmissive region. The optical fingerprint sensor (220) is located between the OLED display panel (230) and the backlight source (210); at least a part of light emitted by the backlight source (210) passes through the first light-transmissive region from the first surface and reaches the second surface, reaches the third surface from the second surface, and passes through the second light-transmissive region from the third surface and reaches the fourth surface; at least a part of the light reaching the fourth surface is used for acquiring a fingerprint image, thereby generating reflective light; the reflective light returns to the second light-transmissive region, reaches the third surface, then reaches the second surface from the third surface, and enters the photosensitive pixel (2221) from the second surface. The performance of the optical fingerprint sensor module is enhanced.
