3M developed a new technology that adds 3D to handheld displays

3M has developed a new optical film that integrates into handheld displays and delivers autostereoscopic viewing - a 3D display without glasses.

The film integrates into the backlight module of an LCD display. Only one LCD panel is required, operating at a 120 Hz refresh rate. Backlight module assembly is nearly identical to existing systems, allowing for simple integration at the assembly stage. The usual optical film stack is replaced with a reflective film, custom light guide, and 3D Film. Through directional backlight technology, left and right images are focused sequentially into the viewer's eyes, allowing full resolution of the display panel. No precision registration during assembly is required.
