Abstract:
An ultrasonic pattern recognition assembly comprising: a substrate; a receiving member comprising at least one receiving electrode disposed on the substrate; a piezoelectric layer disposed on the substrate and covering the receiving member; a seed member comprising at least one seed block disposed on at least a portion of the piezoelectric layer; an insulating member disposed on the seed member and having at least one exposed portion, the at least one exposed portion exposing a portion of a surface of the seed member; and a transmitting member comprising at least one transmitting electrode disposed on the seed member, the at least one transmitting electrode extending from a surface of the seed member exposed by the exposed portion in a direction away from the substrate. A display device and a method of fabricating an ultrasonic pattern recognition assembly are also disclosed.
