Seiko Epson has released a prototype of 2.57-inch color LCD high-resolution 3D display for mobile phones that affords some freedom of viewing position, compared to conventional 3D displays, without using special glasses.
Traditionally, 3D displays present a slightly different image to each eye. Special lenses called “lenticual lenses” are placed in front of the LCD panel in order to each image reaches the correct eye. But, in this way, there is only one viewing point, and this is not enough to mobile displays because it is impossible to control the point of view of the mobile user.
One solution is to capture the object’s image from multiple angles, split it up and display as many images as possible on the panel. So, the more the image is split, the more depth that can be created for the object displayed on the screen, but the less resolution is achieved. This is the problem that Seiko has solved achieved an ultra high resolution of approximately at about 500ppi. Seiko Epson’s solution consists of narrowing the image width that reaches each viewing point and devising special pixel alignment on its LCD display.
Seiko Epson plans to commercialize the display in two years. I don’t know if it will be useful, but I am sure that it will be impressive.
