Patent ID: 7580186

Claim:
A multiple view display for displaying first and second images respectively to first and second observers spaced laterally apart, the multiple view display comprising: a display device arranged to display spatially multiplexed first and second images, wherein the display device includes a pixel plane and a substrate through which said first and second images are transmitted from the pixel plane; a parallax optic arranged to cooperate with said display device to direct light from said first and second images in first and second directions, respectively, with a first angular separation between the first and second directions; and a first optical system for receiving said light from said first and second directions and for directing said light in first and second viewing directions, respectively, to a front plane surface of the first optical system, the first and second viewing directions having a second angular separation different from said first angular separation such that the first observer views the first image from the first viewing direction and the second image is substantially not visible to the first observer, and the second observer views the second image from the second viewing direction and the first image is substantially not visible to the second observer, wherein the multiple view display is configured to provide a plurality of different angles for the second angular separation of the first and second viewing directions of the first and second observers by repositioning the first optical system with respect to the parallax optic or by using a second optical system instead of the first optical system, wherein the second optical system has an optical characteristic different from an optical characteristic of the first optical system, wherein the front plane surface of the optical system, which represents a front surface of the multiple view display, is parallel with the pixel plane of the display device, and wherein either optical system has a divergent lens function.
