Abstract
This paper first proposes a design for privacy monitor that only users at the right angle viewpoint can see the screen clearly, while users at a large enough deviated angle viewpoint cannot see any useful information on the screen. The space where users from that viewpoint can see the screen is called visible space in this paper. Then the visible space of the proposed privacy monitor is completely characterized for IPS screen. By adjusting the distance between the two liquid crystal layers, the size of the visible space can be controlled in such a way that larger distance will result in a smaller visible space, while smaller distance will result in a larger visible space.
