Abstract:
A system and method for providing an acoustically transparent imaging display include a substrate with light sources on one side and perforations having a first visible optical reflectance, the perforations extending perpendicularly to the display surface and being disposed between the light sources. The side of the substrate opposing the light sources faces a black surface of an enclosure.
A layer having a second visible optical reflectance is disposed on the substrate on the side of the light sources. The layer has an acoustical transparency attenuation of at most −10 dB, and when in normal light conditions the difference between the visible optical reflectance of the layer and that of the perforations is lower than the difference between visible optical reflectance of the substrate and that of the perforation.
