Abstract
A fingerprint assembly including: a first circuit board, a second circuit board connected to a side of the first circuit board, a chip connected to a side of the second circuit board away from the first circuit board, a light guide aperture connected between an outer periphery of the chip and the first circuit board, and an annular-shaped light emitting element connected to the first circuit board. The first and second circuit boards and the light guide aperture jointly enclose to define an annular groove matching with the light emitting element, which is arranged in the annular groove. A light entrance surface is formed at a side of the light guide aperture facing the light emitting element and a light exit surface is formed at a side of the light guide aperture away from the first circuit board. The fingerprint assembly solves a problem of uneven light emission.
