optical fingerprint detection device, touch screen and electronic device

An optical fingerprint detection device, a touch screen and an electronic device relate to the technical field of fingerprint identification, and can improve the accuracy of fingerprint identificationunder the condition that the finger is dipped in water. The optical fingerprint detection device includes a light-emitting component, the light-emitting component includes a fingerprint recognition light source (3), the light emitted by the fingerprint recognition light source (3) is incident on the upper surface of the glass cover plate (2) at an incident angle greater than or equal to the lightsignal from the glass cover The total reflection angle of the board (2) incident on the air; the optical fingerprint detection device also includes an optical fingerprint module (4); the optical fingerprint detection device also includes a fingerprint light located between the glass cover (2) and the display screen (1) The reflective layer (01) is used to make the fingerprint recognition light source (3) illuminate the fi
