Straight from CEATEC 2009: Hitachi’s Full Parallax 3D TV
3D TVs hogged the limelight at this year’s CEATEC expo; the booths of top manufacturers appeared to be literally screaming out their 3D TV plans for the future. The only aspect of 3D TVs that can be a bit of a turn off is the special glasses that need to be worn to experience 3D. So, can one ever enjoy 3D without the bulky glasses? By all means yes, with Hitachi’s “Full Parallax 3D TV”. Displayed at the CEATEC 2009, this 10 inch 3D TV can be watched without any special 3D glasses.
The Full Parallax 3D TV can be watched from any possible direction and is based on a technique called “Integral Photography with Overlaid Projection”. According to Hitachi, this TV has a 640 x 480 pixel VGA screen resolution and consists of 16 projectors with a lens array sheet to cover them. This lens array sheet plays the most important role by ensuring parallax due to which the image is adjusted in accordance to the angle from which it is viewed.
A Hitachi spokesperson said that they plan to increase the number of projectors over 10 times by arranging projectors in a higher density using laser-based micro-projectors.
