Philips believes it is only a few years away from releasing a high-end consumer facing TV that shows three dimensional images.

At CES it is showing its current 3D displays, used by businesses signage, but said it will have 3D TVs within two or three years.

It uses a Lenticular Lens System, like old postcards that appear to change when the viewing angle is moved. The 3D image is rendered in the TV, and projects pictures to the left and right eye at the same time.

Nine pictures, at differing angles, are projected and depending where you sit in front of the TV, your eyes see two of those images. It gets its depth from each pixel either appearing to be in or out of the TV.

TVs will be expensive – the 42in version costing about €10,000 and the 20in around €6,000.
