Abstract
The twisted-nematic mode liquid-crystal display (LCD) display used in most laptop computers has the property that the luminance and color changes dramatically as the viewing angle changes. The present paper utilizes this property to embed several images into the LCD display that are viewable depending on the viewing angle. Applications include improving the viewing angle characteristics of LCD displays.
