We have developed an FFS-based LCD that can be switched between two display modes: 1) wide view mode with high contrast ratio and 2) narrow view mode enabling privacy. By combining the new LCD configuration with Switchable Backlight Technology, our 5.3-inch prototype has successfully enabled: 1) enhanced optical properties and 2) privacy mode with the appearance from side viewing direction darker that prevents unauthorized image viewing.
