What is the difference between 3D Integrated and 3D ready?

By adding a sense of picture depth and dimensionality, 3D TVs create a more engaging viewing experience that's similar to watching a 3D movie in a theater. Like 3D movies, 3D TV requires that each viewer wear special glasses to see the 3D effects. 3D TV requires the use of wireless "active shutter" glasses.

Whether a 3D TV uses LCD or plasma screen technology, all 3D TVs use a specially designed screen that can display two different versions of a video image by alternating the video frames at very high speed. 3D video is basically two full-resolution 1080p images, one for your left eye and one for your right. The shutter glasses' lenses darken and lighten rapidly in coordination with the screen's flashing images. The timing of the shutter glasses is wirelessly controlled by an "emitter" that is usually built into the TV. The system creates an immersive viewing experience. True 3D viewing also requires a 3D video source, like a 3D Blu-ray player playing a 3D movie.

Active shutter glassesTo see three-dimensional effects on a 3D TV screen, each viewer must wear a special type of 3D glasses called "shutter" glasses. Also called "active" glasses, these battery-powered liquid-crystal glasses are able to lighten or darken hundreds of times per second to alternately block out the left or right lens in coordination with the video frames flashing on screen. The lenses aren't displaying images, just switching between dark and clear. To anyone not wearing shutter glasses, a 3D TV picture will look blurry. Active glasses are far more technologically advanced than the disposable 3D glasses handed out in movie theaters.
