3M Brings 3-D to Mobile Phones

By: E&P Staff 3M's Optical Systems Division has developed a field sequential 3-D optical film that enables auto-stereoscopic 3-D viewing on mobile phones and other handheld devices without the need for glasses.

The company will introduce the 3-D display for mobile in Korea next week.

"Our 3-D optical film solution is designed to enhance communication and interaction by providing an immersive, compelling visual 3-D experience for mobile devices," Optical Systems Division Vice President Jim Bauman said in a statement.

The 3-D optical film can be integrated into the backlight module, according to 3M. It requires only one LCD panel, and operates at a 120Hz refresh rate. Assembly is nearly identical to existing systems, facilitating its integration.

The standard optical film stack is replaced with a reflective film, custom light guide and 3-D film. By using directional backlight technology, left and right images are focused sequentially into the viewer's eyes, enabling a full-resolution display of the panel.
