Unique new 3D technology without glasses

Mobile phone users are about to see 3D images on screen thanks to the breakthrough technology, which was first introduced on March 20.

The new 3-D display, developed by Hewlwatt-Packard Electronics, does not require the use of special glasses to look at and is particularly suitable for small devices.

According to the inventor, this technology will revolutionize data visualization, medical training and entertainment with high-resolution solutions suitable for multi-dimensional 3D display applications. Both animations and stills are viewable in full color from angles with distances up to 91cm.

Movies like Avatar or Alice in Wonderland can only be viewed in 3D with a pair of special glasses. But the new technology, using the so-called 'diffraction optical' effect , is reflected backward when the obstacle is obstructed, allowing the naked eye to see the 3D image.

However, the application of technology to create depth 3D images into mobile devices is difficult because the display needs to be thin, high resolution and have a wide viewing space.

In-display illumination by Dr. David Fattal and colleagues at Hewlett-Packard Research Institute, Palo Alto, California, have met these requirements.

The most important point of the screen is the lighting technology of guided light rays based on light-emitting diodes and a thin structure called the waveguide structure that is capable of controlling electron waves in the spectrum.

Dr Fattal, a quantum scientist, says no 3D multi-dimensional viewing solution is suitable for devices such as clocks, phones and tablets. High resolution images and a fairly short viewing distance.

"We offer a multi-dimensional noise-canceling technology that enables high-resolution 3D imagery, and a wide viewing angle of up to 180 degrees and with a viewable distance up to to 1m, " Dr Fattal said.

Fatal also said that the technology is very promising for use on 3D mobile screens.
