COMMUNICATION DEVICE TO SENSE ONE OR MORE BIOMETRIC CHARACTERISTICS OF A USER
A communication device for sensing one or more biometric characteristics of a user. The device includes a cover structure, a layer of output pixel elements, a layer of biometric input pixel elements, and a processor. The cover structure includes an exterior surface. The layer of output pixel elements is positioned below the exterior surface and configured to provide an output through the exterior surface toward the user. The output pixel elements being at least one of light emitting pixel elements and piezoelectric-out pixel elements. The layer of biometric input pixel elements is positioned below the exterior surface to receive a reflected biometric input passing from the user through the exterior surface. The biometric input pixel elements being at least one of light detecting and piezoelectric-in pixel elements. The processor is connected to the biometric input pixel elements to process the reflected biometric input.
1 . A communication device configured to sense biometric information from a finger, comprising:
an exterior surface;
a layer of display light emitting output pixels positioned below the exterior surface to display images through the exterior surface; and
piezoelectric material positioned below the layer of display light emitting output pixels, the piezoelectric material configured to provide an output in a direction through the exterior surface toward the finger, and to receive data corresponding to the output reflected from the finger.
