Abstract: Microphones are located between pixel display elements (e.g., micro-LEDs and OLEDs) in a display. Display-integrated microphones allow displays to have thinner bezels. Audio processing components can also be incorporated into the display and allow audio processing offloading from processors external to the display. Arrays of microphones allow for the beamforming of received audio signals to enhance the detection of sound from remote audio sources. Piezoelectric elements can also be integrated into a display to allow for localized haptic feedback. Integrated piezoelectric elements can act as speakers and beamforming techniques can be used to activate sets of piezoelectric elements in coordination to direct sound to a specific location external to the display. Piezoelectric elements can aid in display thermal management by creating acoustic waves to move heated air within a display to create a more uniform thermal profile within the display or to remove excess heat from the display.
