Abstract
A video eyewear device in which parallel side-by-side video signals are driven as analog signals to the left and right displays, with timing controlled by a common sampling clock. A left display sampling clock burst occurs during an active video period and the right display burst occurs during the same portion of the active video period.
Claims20
A video eyewear device comprising:
- a head-mounted eyewear, configured to host:
- a receiver, for receiving a digital video stream having encoded therein three-dimensional video information;
- a left display;
- a right display;
- a left video driver and a right video driver, each coupled to the receiver for receiving the digital video stream, and providing a left video signal to the left display and a right video signal to the right display;
- and
- a timing controller, for generating a pixel sampling clock signal to be applied to the left video signal at the left display and the right video signal at the right display, such that an active pixel sampling clock period for the left video driver occurs during the same time as an active pixel sampling clock period for the right video driver.

A method of driving 3-dimensional binocular eyewear from a standard video stream, the method comprising:
- at a subject 3-dimensional binocular eyewear having a left display and a right display:
- receiving an input digital video stream having encoded therein three-dimensional video information;
- from the received digital video stream, providing a left video signal to the left display and a right video signal to the right display said providing the left video signal to the left display being by a left video driver and providing right video signal to the right display being by a right video driver;
- and
- causing an active pixel sampling clock period associated with the left video driver to occur during the same time as an active pixel sampling clock period associated with the right video driver.

A method of driving 3-dimensional binocular eyewear from a standard video stream, the method comprising:
- at a 3-dimensional binocular eyewear, receiving a digital video stream having encoded therein three-dimensional video information, said eyewear having a left display and a right display;
- using a left video driver and right video driver, receiving the digital video stream and providing a left video signal to the left display and a right video signal to the right display;
- and
- shifting with respect to one another at least one of the digital video signals at the left video driver and the digital video signals at the right video driver, said shifting using a pixel position shifter.
