Abstract
A biometric sensor configured to detect a biometric information is provided. The biometric sensor includes a light emitting layer and a touch detection layer; an encapsulating cover on the light emitting layer; a photo-sensing layer configured to detect at least a portion of a light totally reflected by a surface of the biometric sensor in touch with a skin of a user; a touch sensing circuit configured to determine a touch position of a touch; a processor configured to determine a scanning region based on the touch position, and configured to control the light emitting layer to form a scanning light source to scan the scanning region in a scanning pattern; and a biometric information analysis circuit configured to determine a light intensity distribution of a reflected light reflected by the surface of the biometric sensor, and configured to determine the biometric information based on the light intensity distribution.
