Abstract

The invention relates to a key structure and electronic equipment. The key structure comprises a key cap and an optical fingerprint identification module, wherein the key cap is provided with a top plate, and the top plate comprises a pressing surface and a bottom surface which are oppositely arranged; and the optical fingerprint identification module is located on one side of the top plate, the optical fingerprint identification module comprises an image sensor, and the image sensor is attached to the bottom surface of the top plate. Through the adoption of the optical fingerprint identification module, the increase of the thickness of the top plate becomes possible, so that the strength of the key structure can be effectively improved, and the key structure is better compatible with a pressing function and a fingerprint identification function.
