Abstract: A system for augmenting displayed content with embedded invisible information such as visual or audio information, or a network link to the augmented information. The system includes a display module, first and second backlight modules, and a controller. The first and second backlight modules selectively provide visible light and invisible light, such as infrared light, to the display module. The controller provides first and second frames of content, alternating in a time sequential manner, to the display module with the first frames of content backlit by the first backlight module and the second frames of content backlit by only the second backlight module. The second frames of content provide invisible information embedded with the first frames of content and can be detected an infrared camera and used to display or provide augmented information.
