Augmented information display
First Claim
1. A system for augmenting displayed content, comprising:
- a display module having red, green, and blue sub-pixels;
a first backlight module for providing visible light to the display module;
a second backlight module for providing only invisible light to the display module;
a controller, coupled to the display module and the first and second backlight modules, for providing first frames of content and second frames of content to the display module with the first and second frames of content alternating in a time sequential manner,wherein the first frames of content are backlit by the first backlight module, the second frames of content are primarily backlit by the second backlight module, and the second frames of content are primarily transmitted through the red sub-pixels;
an infrared camera that captures the second frames of content; and
a processing unit, coupled to the infrared camera, that uses the captured second frames of content to provide information related to the first frames of content.

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.

9. A method for augmenting displayed content, comprising:
-
providing to a display module, having red, green, and blue sub-pixels, first frames of content backlit by a first backlight module; providing to the display module second frames of content primarily backlit by a second backlight module; alternating the first and second frames of content provided to the display module in a time sequential manner, wherein the first backlight module provides visible light to the display module, and the second backlight module provides only invisible light to the display module; primarily transmitting the second frames of content through the red sub-pixels; capturing the second frames of content using an infrared camera; and using the captured second frames of content to provide information related to the first frames of content. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
