Apple's U.S. patent 7,843,449: Three-dimensional display system
Christoph H. Krah of Los Altos is the single named inventor on Apple's US 7,843,449 ,
with abstract:
A three-dimensional display system provides a projection screen having a predetermined angularly-responsive reflective surface function. Three-dimensional images are respectively modulated in coordination with the predetermined angularly-responsive reflective surface function to define a programmable mirror with a programmable deflection angle.
with first claim:
A method of displaying three-dimensional images, comprising: providing a projection screen having a spatial filter defining a predetermined angularly-responsive reflective surface function; determining the left and right eye locations of at least one observer in proximity with the projection screen; projecting left and right sub-images of a three-dimensional image toward the projection screen; and angularly and intensity modulating the left and right sub-images respectively in coordination with the predetermined angularly-responsive reflective surface function to define respective discrete light paths that respectively direct the left and right sub-images to reflect from the projection screen to the respective left and right eye locations to provide a three-dimensional viewing experience.

I agree with Apple that watching 3D movies, TV, and other content with those glasses is anachronistic, and I congratulate the company on this patent. It looks to me like 3D TVs and internet TVs will constitute much of the market for television in the near future. Apple's sure to eventually rake in quite a decent amount in patent enforcement revenue on this technology.
