Patent ID: 10531212

Abstract:
Described is a screen surface layer comprising a plurality of light-emitting pixels including a plurality of red pixels, a plurality of green pixels and a plurality of blue pixels; a transducer layer comprising a plurality of acoustic transducers, wherein the transducer layer is affixed below the screen surface layer; and a cover layer having a plurality of cylinder-shaped perforations, wherein the cover layer is affixed above the screen surface layer. In addition, an average “transducer model” describing a phasor distribution in space may be produced describing the output signal at the carrier frequency in the air at a known spatial offset from an averaged transducer. Further, phased array systems may have numerous individual transducer elements that will likely fail before the product incorporating the transducers reaches end-of-life. By detecting such failed transducers, the transducer array may function at peak performance by working around the missing transducer output.
