Abstract:

An apparatus projecting or displaying images to a viewer. The apparatus or Pepper's ghost system projects or displays an image stream onto a reflective element with a first surface receiving and reflecting a portion of light associated with the image stream to the viewer and a second surface opposite the first surface. The apparatus includes a cleaning assembly including an air supply providing a volume of flowing air and an ionizing mechanism for receiving the flowing air and outputting an ionized air flow. The ionized air flow is directed over the second surface of the reflective element. The reflective element is positioned at a non-vertical display angle. An outlet of the cleaning assembly is positioned adjacent an upper edge of the reflective element, and the ionized air flow is output from nozzles as laminar air flow with a flow rate chosen to mitigate dust collection on the upper second surface.
