Description of issues/problems that this invention addresses:

While viewing a laptop on an airplane or in a conference, adjacent people can view the display. There are add on screens to reduce the viewing angle of the display but these add on screens may reduce the viewing to the extent that user himself may have difficulties viewing his display at a convenient viewing position.

How this invention overcomes the problem described above: While viewing a laptop on an airplane or in a conference, adjacent people can view the display. There are add on screens to reduce the viewing angle of the display but these add on screens may reduce the viewing to the extent that user himself may have difficulties viewing his display at a convenient viewing position.

Other possible uses for this invention: In addition to security, it could be used to allow multiple content to be viewed on a single display. This has been proposed by others previously, but not necessarily on an LCD display as LCD displays have only recently been able to attain 120 Hz frame rates.
