Abstract

The present disclosure relates to a display assembly, a method of using the display assembly, and an electronic device, which uses the display assembly, for detecting an identification surface of an object (e.g., a fingerprint) using a detection signal, which penetrates the object and reflects a target signal representative of at least part of the identification surface (e.g., the orthographic projection of the fingerprint) onto an identification area on a display. A signal receiver (i.e., comprising a signal receiver) then detects the target signal. The target signal can be used by a processor to further authenticate whether it corresponds to an authorized user. The display assembly includes a display having an identification area, a signal transmitter (i.e., comprising a signal transmitter) configured to generate a detection signal when an object is within a preset distance of the identification area, and a signal receiver configured to detect the target signal.
