Epson's 3D phone display

Seiko Epson developed a small, 2.57-inch display that is able to display 3D images without a projector of any kind and, at 1024x768 (XGA) or 550ppi resolution, it is also one of the world's highest resolution 3D displays. The display is meant for cell phone applications, and requires no special lenses to view the 3D effect. To achieve the 3D effect, the company used a lenticular or bi-convex lens so the same pixels can be seen from different angles.

The images are shot by a few cameras from slightly different angles before being resolved into pixels and arrayed on the pixels of the display based on a calculation that is believed to give the best 3D effect. Because of humans' ability to perceive 3D images by piecing together separate images, makes the display effective.

Seiko jumped several hurdles by using more pixels in its display and skewed the balance of horizontal-to-vertical pixels in favor of the former, as human eyes are less sensitive to pixels orientated in the vertical direction. Additionally, it has cut the cycle in which images change depending on the viewing image width. Previously, it was believed the ideal distance of 2.4 to 2.6 inches between human eyes was ideal, but Seiko halved it to between 1.2 and 1.3 inches.

The company has plans to commercialize the display in two years. [via Tech-On!]
