Abstract
The disclosure provides a fingerprint identification panel. The fingerprint identification panel includes an encapsulation layer, a light emitting element, a light sensing element and a dielectric layer. The light emitting element and the light sensing element are on a same side of the encapsulation layer, and the encapsulation layer is configured to enable light emitted from the light emitting element to be totally reflected in the encapsulation layer; the dielectric layer is between the encapsulation layer and the light sensing element and in direct contact with the encapsulation layer, and is configured to enable the light totally reflected by the encapsulation layer to be received by the light sensing element after passing through the dielectric layer, and a refractive index of the dielectric layer is smaller than that of the encapsulation layer.
