Abstract

A dual view display system that includes a display device and a first louver device. The display device is configured to display a first image at a display location to a first person at a first location and display a second image at the display location to a second person at a second location. The first louver device configured to substantially restrict a first field of view of the first image to the first person. The system may also include a second louver device configured to substantially restrict a second field of view of the second image to the second person. Such an arrangement restricts the fields of view so that, for example, a vehicle driver can not lean over and view something intended only for a vehicle passenger, such as a movie.

Claims

1. A dual view display system comprising:

a display device configured to display a first image at a display location to a first person at a first location and display a second image at the display location to a second person at a second location; and

a first louver device configured to substantially restrict a first field of view of the first image to the first person, wherein the first louver device includes a layer of advanced light control film.

2. The system in accordance with claim 1, wherein the first louver device overlays the display device.

3. The system in accordance with claim 1, wherein the system further comprises a second louver device configured to substantially restrict a second field of view of the second image to the second person.

4. The system in accordance with claim 3, wherein the first louver device and the second louver device overlay the display device.

5. The system in accordance with claim 3, wherein the first louver device and the second louver device include a layer of advanced light control film.

6. The system in accordance with claim 1, wherein the display device includes

a display element configured to display the first image on a first portion of the display element and display the second image on a second portion of the display element distinct from the first portion;

an optical element configured to direct the first image to the first person and direct the second image to the second person.

7. The system in accordance with claim 1, wherein the display device includes

a display element configured to display the first image during a first time period and display a second image during a second time period distinct from the first time period;

and

an optical element interposed between the display element and the display location, said optical element configured to direct the first image to the first person during the first time period and direct the second image to the second person during the second time period.

8. The system in accordance with claim 7, wherein the optical element includes a switchable minor characterized as having a transparent state and a reflective state.
