New 3D technology looks to the past to overcome the problems of present systems

Knowing of the problems with current 3D technologies, such as the noticeable dimming of the image, restricted viewing angle and even reports of people suffering headaches and nausea when watching for an extended peiod 3D images, German and Swiss researchers say they have developed a technology that overcomes these problems. The discovery is the result of three friends of the German company Infitec that hope to develop a 3D LCD flat screen capable of displaying full resolution of the new formats of high definition televisions.

Using a wavelength band of color more closely on the glasses, the company has been using specific wavelengths of red, green and blue for the right eye and different wavelengths of the same color for the left eye, thus providing different images for both eyes, giving the viewer the illusion of 3D.

Along with the Swiss company Optics Balzers, the Infitec secured funding to start developing a 3D LCD screen. While Infitec was responsible for research to better use of sign and lighting on the monitor and software for this, Optics Balzers has developed special filters for lighting and the glasses.

They decided to create a new optical design for the monitor, combined four LEDs - two green, one red and one blue - to create a range of colors they needed. The end result was a 23-inch monitor that the team calls Dualplex Display, which causes less strain on the eyes than other 3D technologies, the glasses do not darken the ambient light and screen can be viewed from all angles without distorting the images 3D.

The partners have applied to patent the screen in Germany and are in the process of submitting patents in other countries with the ultimate goal of selling the 3D LCD  households. Initially, though, they think they will find it easier to reach niche professional markets such as medical professionals - using 3D images to help surgeons doing operations.
