The Ultra-D optical system is a stack of layers of refractive and diffractive optical elements bonded to a liquid-crystal display. Optical system – 3D hardware including firmware allows:

  • Glasses-free experience

  • High quality 3D

  • Full contrast and brightness

  • True color reproduction

The technology can be applied in flat panel products ranging from displays as small as 4 inches to the largest mass-produced displays of 84 inches. Consequently, the Ultra-D technology can be integrated on smart phones, tablets, PC’s, picture frames etc.

How does it work?

The light of individual sub-pixels is directed from the screen and projected into space; it generates virtual pixels. Virtual pixels merge in the space and form a complete view for each eye of the viewer (see picture below). From that point the viewer’s brain takes over processing both views in the same natural way, as it is used to in the real world, creating a natural 3D experience.
With the Ultra-D technology the viewing areas are repeated in a horizontal way and the transitions between these areas are made smooth. So, a viewing area is not divided in discrete views as is done in most other technologies, but the optical system creates an almost continuous light field in front of the screen.

Immersive Viewing Experience

The technology does not use special equipment as sensors for eye or head tracking. This means there is no limitation to the number of viewers and there is no fixed viewing position with respect to the screen. It allows the viewer to move freely in the range of recommended viewing angle of approximately 120 degrees and feel as if looking through a window to the world.

Viewing Distance

The view configuration of the newest Ultra-D displays is such, that it allows the viewer to experience 3D from distances other than the optimal viewing distance. Moreover, even from a distance twice the optimal one the viewer still experiences 3D.The future development of the technology will allow the viewer to choose an optimal distance by adjusting settings with a remote control. However in the current implementation it has a fixed default factory setting, which depends on the application of the screen.

For comfortable viewing of a glasses-free 3D display, it is important to have a convenient viewing distance. The optimal viewing distance of the Ultra-D screens is rather flexible. It is directly related to a design choice and depends on the purpose of the display. Obviously for digital signage applications the 3D effect is expected to be visible from a distance of about 10m and closer. For the consumer market the recommended optimal distance is 3 m, where the size of an average living room is taken into account.

Depth/Pop

The depth of the screen and pop out   of the Ultra-D display can be adjusted by the viewer by using the remote control while playing video.

Other aspects

Commonly discussed challenges of 3D without glasses displays are: brightness of a screen, color reproduction and field/frame rate. However, these factors are not affected by the Ultra-D optical system. They are dependent on the quality of the liquid-crystal panel used. Commonly discussed challenges of 3D without glasses displays are: brightness of a screen, color reproduction and field/frame rate.
