Problems solved by technology
In recent years, with the miniaturization requirements of electronic devices such as mobile phones and tablet computers, the requirements for the thinning and miniaturization of fingerprint recognition modules installed inside electronic devices are also getting higher and higher. The volume of the optical detection device for identification should also be continuously reduced, and in order to ensure the accuracy of biological information identification, the collection area of biological information on the display screen should be at least within a small area, which leads to fingerprint identification. The structure of the module is difficult to further shrink, which greatly affects the miniaturization of electronic equipment

The invention provides a biological information recognition module and electronic equipment, and relates to the technical field of electronic equipments. The biological information recognition module provided by the invention is a fingerprint recognition module. The biological information recognition module comprises an optical path guide layer and an optical sensor, a light path guide layer comprises a plurality of light channels, the optical sensor comprises a plurality of photosensitive pixel units, and at least two adjacent photosensitive pixel units form a photosensitive pixel unit group; a biological information recognition module further comprises a gap area arranged between the at least two photosensitive pixel unit groups, and a light beam carrying fingerprint information above the gap area is received by at least one photosensitive pixel unit through the light channel. The electronic equipment comprises a display screen and a biological information recognition module arranged below the display screen. According to the biological information recognition module and the electronic equipment, the light beams carrying fingerprint information in a larger area range can be received under the condition that the overall size of the module is not increased.
