3M Enhances 3D for Handhelds, sans the Geeky Glasses
“One” may be the loneliest number but “3” seems to have plenty of companies these days as 3M (the St. Paul, Minn., firm) said its latest foray into 3D (the fast-emerging technology for consumers) said it has produced a new form of field-sequential 3D optic film for mainly handheld devices.
And here’s the good part: The auto-stereoscopic 3D film that targets cell phones, small video game consoles, and other portable digital devices requires no glasses.
The company said its 3M 3D optical film can be integrated into a small device’s backlight module to produce 3D images. The 3D film requires only a standard LCD panel, and can operate at a refresh rate of 120Hz.
Another big plus for their new film, 3M says, is that at the crucial assembly-line stage, assembly of the backlight module is nearly identical to existing systems. That would mean minimal expenditures for integrating new assembly protocol, among other factors. (When using directional backlight technology, left- and right-eye images are focused sequentially into the viewer’s eyes — allowing full-resolution panel display.
3M plans to first show its 3D display mobile concept at the Korea Electronics Show Oct. 13-16 (Booth 1600).
