Patent abstract
This disclosure provides systems, methods and apparatus related to an ultrasonic sensor for detecting ultrasonic energy. In some implementations, the ultrasonic sensor includes a piezoelectric receiver layer bonded with an adhesive to an array of pixel circuits disposed on a substrate, each pixel circuit in the array including at least one thin film transistor (TFT) element and having a pixel input electrode electrically coupled to the pixel circuit. Methods of forming ultrasonic sensors include bonding piezoelectric receiver layers to TFT arrays.
