3M’s optical systems division has developed a new, field sequential 3D optical film for handheld devices, enabling true auto stereoscopic 3D viewing on mobile phones, gaming and other handheld devices without the need for glasses.
 
The 3D optical film can be integrated into the backlight module. The film only requires one LCD panel and operates at a 120 Hz refresh rate. Backlight module assembly is nearly identical to existing systems, allowing for simple integration at the assembly stage. The standard optical film stack is replaced with a reflective film, custom light guide and 3D film. By using directional backlight technology, left and right images are focused sequentially into the viewer’s eyes. 3M will show its 3D display for mobile concept at the Korea Electronics Show, October 13-16.
