TECHNIQUES FOR BEAMFORMING PRESSURE WAVES

Abstract:

Certain aspects of the present disclosure provide techniques for beamforming pressure waves. A method for operating an apparatus configured to beamform ultrasonic pressure waves may generally comprise emitting, via a pressure wave module of the apparatus, beamformed ultrasonic pressure waves through a display module of the apparatus, wherein: the display module comprises a first plurality of layers; the pressure wave module comprises a second plurality of layers; the second plurality of layers comprises at least a copolymer layer, a conductive layer, a dielectric protection layer, and a thin film transistor (TFT) glass layer; and an order of the second plurality of layers in the pressure wave module depends on an acoustic resonance value associated with the display module.
