Fingerprint detection device and electronic device

Abstract

Provided is a fingerprint detection device and an electronic device, which are suitable for an electronic device with a display screen, wherein the bottom layer of the display screen is an opaque layer, and a window penetrating the opaque layer is formed on the opaque layer; the fingerprint detection device comprises: an optical path layer and a first sensor chip, wherein the optical path layer is arranged above the first sensor chip; a substrate, a fixing structure and a pressure-sensitive adhesive; the first sensor chip and the fixing structure are arranged on the upper surface of the substrate, and the upper surface of the fixing structure is fixed to the lower surface of the display screen through the pressure-sensitive adhesive; a holding portion; a gold finger is arranged on the first side portion of the substrate, and the side portion of the fixing structure includes the first side portion and at least one second side portion other than the first side portion, and the holding portion is fixedly arranged on any side portion of the at least one second side portion, and the holding portion is used to peel the fingerprint detection device from the display screen. The solution of the present application can reduce the complexity of installation or disassembly of the fingerprint module to improve practicality.
