Abstract: The present disclosure provides an optical fingerprint identification apparatus and an electronic device. The apparatus includes a fingerprint identification module disposed under a backlight module of the liquid crystal display. The fingerprint identification module includes an optical sensor and a light source disposed adjacent to the optical sensor; the light source is used to emit a detection light to the fingerprint detection area of the liquid crystal display, and the detection light passes through the liquid crystal display via a transmission part of the backlight module and irradiates to a finger above the liquid crystal display to form a fingerprint detection light carrying fingerprint information; and the optical sensor is used to receive the fingerprint detection light to acquire the fingerprint information; where the fingerprint detection light passes through the liquid crystal display and is transmitted to the optical sensor via the transmission part of the backlight module.
