Dual view display system
A dual view display system that displays two different images in different directions using a single display device. The dual view display includes a first optical element overlaying a first portion of the pixels and configured to direct light emitted from the first portion of the pixels toward a first direction, a second optical element overlaying a second portion of the pixels and configured to direct light emitted from the second portion of the pixels toward a second direction distinct from the first direction, and an optical barrier arranged between the first optical element and the second optical element effective to prevent light from propagating therebetween.
1. A dual view display system comprising:
a single display device comprising a plurality of pixels configured to control light emission and operable to display images on a display surface;
a first optical element characterized as a first prism element overlaying a first portion of the pixels and configured to direct light emitted from the first portion of the pixels toward a first direction;
a second optical element characterized as a second prism element distinct from the first prism element, said second optical element overlaying a second portion of the pixels and configured to direct light emitted from the second portion of the pixels toward a second direction distinct from the first direction; and
an optical barrier arranged between the first optical element and the second optical element effective to prevent light from propagating therebetween, wherein the first optical element overlies a first pixel portion of each pixel and the second optical element overlies a second pixel portion of each pixel such that light from each pixel can be directed in the first direction and the second direction, wherein the system further comprises a first shutter device arranged between the first pixel portion and the first optical element and a second shutter device arranged between the second pixel portion and the second optical element.
2. The system in accordance with claim 1 , wherein the display device is characterized as having a display resolution, and the system is configured such that a first image projected in the first direction and a second image projected in the second direction are each characterized has having the display resolution.
3. The system in accordance with claim 1 , wherein the first optical element, the second optical element, and the optical barrier form an optical assembly that is movable to a first position whereby the first optical element overlies a pixel, and a second position whereby the second optical element overlies the same pixel.
4. The system in accordance with claim 3 , wherein the system further comprises an actuator coupled to the optical assembly effective to move the optical assembly between the first position and the second position.
