Sanyo took the opportunity of this week's Consumer Electronics Show in Las Vegas to unveil what could be the hardcore gamer and telly addict's ultimate fantasy.
It demonstrated a prototype of the world's first 3D display that doesn't require the use of any special glasses. The 16-inch display offers resolutions of 1280 x 1024, with a 18-inch 1280 x 1024 resolution version in the pipeline.
Sanyo's "Image-splitter" technology makes possible viewable 3D images to the naked eye. The device contains a set of parallax images that are displayed on alternate columns of the liquid crystal panel. It also houses an Image-splitter, which is collection of vertical stripes, each with a slit corresponding to one pair of columns on the unit's liquid crystal display.
This means that when watching from a viewing position 40-inches from the screen, parallax images are separated. When images reach the eyes they are magically recognised in 3D form.
The display also includes a head-tracking sensing feature, consisting of an IR LED, a CCD camera and a control circuit. Light from the IR LED is reflected at a reflection film behind the viewer. The CCD then senses the reflected light and the control circuit works out the position of the viewer's head. Furthermore, the exchange of the of the left and right eye images is combined with the shift of the Image-splitter, meaning the 3D images can be viewed from a wide area.
