Abstract

A display panel includes a first polarizer, two twisted nematic cells, a second polarizer, and a display. The first twisted nematic cell transfers light in response to a first control signal. In an off state, a polarity of the light is rotated in a first twist. In an on state, the polarity of the light is maintained. The second twisted nematic cell transfers the light in response to a second control signal. In the off state, a polarity of the light is rotated in a second twist. In the on state, the polarity of the light is maintained. The display generates an image in the light in response to a display signal. While the twisted nematic cells are in the off state, the image is viewable in a public viewing angle. While the twisted nematic cells are in the on state, the image is viewable in a private viewing angle.
