Japanese company Seiko Epson presented a 3D-display for mobile phones. The new device allows you to show three-dimensional images without the use of special glasses. The physical size of the screen is rather modest (2.57 - inch diagonal), but permit high (1024 × 768, 500 pixels per inch). Seiko Epson plans to begin commercial distribution of produce in the next two years.

In a special device used lenticular lens through which images can be viewed from different angles. Most lens consists of a huge number of small convex lenses (each does not exceed in size a few pixels). To form a three-dimensional image should be a few cameras (up to 8 pieces), which remove the object from different angles. Then the resulting images disassembled and placed on the pixels on the display after a small processing.

Because of that right and left eyes see a picture from different angles, the final picture looks three-dimensional. The very technique is not new. It was established back in the 19 century but effectively use it in practice in mobile phones succeeded only now.
