Abstract:
1. A display system for displaying an out-the-window (OTW) scene to a user, said system comprising: a screen structure comprising a plurality of rear-projection screen elements supported angulated with respect to each other so as to display said out-the-window scene to the user; said screen elements each being substantially planar and isosceles trapezoidal in shape and each having a short edge and a long edge parallel to each other and separated from each other by a height distance, the long edge having a length such that a ratio of the length of the long edge to the height distance is in the range of 14:9 to 20:9; said screen elements each having opposing side edges extending between the long and short edges thereof, each screen element having at least one of the side edges thereof adjacent one of the side edges of another of the screen elements with the screen elements oriented so that the short edges thereof are positioned adjacent each other and the long edges thereof are positioned adjacent each other; and a plurality of high-definition video projectors supported outside the screen structure and each configured to rectilinearly project a rectangular high-definition field of pixels having an aspect defined as a ratio of a horizontal dimension of said field of pixels to a vertical dimension thereof; and the high-definition video projectors each rectilinearly projecting respective high-definition video images of a respective portion of the out-the-window scene onto a respective one of said screen elements, the aspect of each of the high-definition video projectors being substantially equal to the ratio of the long edge length to the height distance of the respective screen element; the video images each constituting a respective isosceles trapezoidal area that is a subset of pixels of a rectangular output image of the rectangular field of pixels of the projector thereof, where the trapezoidal area extends across substantially the horizontal and vertical dimensions of the field of pixels, and has a first number of pixels along a long edge thereof and a second number of pixels along a short edge thereof, such that the trapezoidal area has a shape that corresponds to the shape of the screen element on which the video image is projected, wherein a ratio of the length of the short edge to the length of the long edge of the screen element is equal to a ratio of the second number of pixels to the first number of pixels.
