Abstract
A light-emitting prompting device is provided. The light-emitting prompting device includes a fingerprint button unit received in a receiving hole of a cover assembly of an electronic apparatus. The fingerprint button includes a fingerprint recognition device and a light-emitting portion. The fingerprint recognition device includes a fingerprint cover, a fingerprint chip, and a circuit board. The fingerprint cover defines a light-shielding region and a light-transmitting region. The light-emitting portion is located at one side of the circuit board that is away from the fingerprint chip; a projection of the light-emitting portion on the cover extends beyond a projection of the circuit board, and further extends into the light-transmitting region, such that the light-emitting portion shields the light-transmitting region. A fingerprint button and an electronic apparatus are further provided.
