Abstract
A fingerprint apparatus and an electronic device are provided. The fingerprint apparatus includes a photosensitive unit, a microlens film, and a support part. The photosensitive unit and a display of the electronic device are arranged to be opposite to each other. The microlens film is disposed between the photosensitive unit and the display. There is an assembly gap between the microlens film and the display, and a first surface, facing the display, of the microlens film is provided with the support part. A first distance between the support part and the display is smaller than a second distance between the microlens film and the display. The assembly gap has a first refractive index, the display has a second refractive index, and the microlens film has a third refractive index.
