Thin film technology helps cell phones to go 3-D

摘要

Embedding microlenses in thin films could bring 3-D movies and games to mobile devices.rnA new thin-film technology developed by 3M could enable mobile devices such as cell phones to show 3-D images without the need for special glasses.rnDubbed Vikuiti 3-D, the technology works by guiding slightly different images to the viewer's left and right eyes. Provided that the device is held relatively still, the viewer experiences an "auto-stereoscopic" effect - a sense of depth to the image.
