Seiko Epson Corp developed a 3D display that is targeted at mobile phones and can show high-resolution 3D images visible to the naked eye with no special glasses. Despite its small size (2.57 inch), the 3D display features a pixel count of 1024 × 768 (XGA). Seiko Epson plans to commercialize the display in two years, the company said. "The resolution of the display is about 500ppi," said Goro Hamagishi, general manager of the Display Development Center "It is one of the world's highest resolutions of the direct-view-type displays that do not use projectors." To display 3D images, a special lens called "lenticular lens" is placed on pixels so that different images can be seen from different angles. A lenticular lens is composed of an array of many hog-backed convex lenses, each of which is as large as a few pixels.
