摘要: An apparatus including an electronic display and a stationary part, the stationary part configured to overlie the display face of the electronic display such that the display face of the electronic display is positioned behind the stationary part, the electronic display/display face configured to vibrate with respect to the stationary part, vibration of the electronic display/display face configured to displace air adjacent to the plane of the electronic display to generate sound waves in the direction of the stationary part, wherein the stationary part is substantially acoustically transparent and configured such that the sound waves generated by the vibrations are able to radiate through the stationary part.

摘要: The specification and drawings present a new apparatus and method for using a spectrally selective mirror/filter to facilitate high efficiency of backlighting and high reflectivity of ambient light in an electronic display. The spectrally selective mirror/filter (or optical filter) may be placed between an upper display (spatial light amplitude modulator) and a backlight unit comprising light sources generating primary colors such as RBG of a display color gamut. This optical filter has a high reflectivity of visible light except for narrow-band transmission windows substantially coinciding with the primary colors.
