Abstract
A first embodiment of the invention permits an extension of battery life through detection of the display synchronization signals of a computer and a power management system. The power management system also eliminates need for batteries through use of a 5V power source from pin 9 of the VGA port. A second embodiment improves the ease of use and the utility of the 3D system through removable glasses with improvements over the previous design. These embodiments have improved manufacturability through the use of design that is tolerant of poor quality, low cost components with low electrical tolerances
Claims3
A shutter glass control apparatus for a 3D stereoscopic display system comprising:
- a vertical sync signal conditioner with an input coupled to a vertical sync input, and with outputs coupled to a field ID generator and a power management system;
