Abstract: Apparatus for displaying at a screen area a light image taken from an image source using light pipes to transmit component elements of the source image which are arranged in a pattern at the screen area to compose the display image on an enlarged scale, the light pipes being spaced apart at the screen area to provide the desired enlargement of the displayed image and to leave interstices through which sound can pass from a loudspeaker behind the screen, the image source being either a complete image whose component elements are continuously present, a scanned image where only part of the elements are actually present at the source at one time, or scanned series of individual image elements appearing successively in time, the necessary persistence to compose a complete image being in the observer's eye or being present in the apparatus as a luminescent substance added to the display screen or to the light pipes.
