Huge 3D Displays Without The Need Of 3D Glasses Possible - TriLite And TU Vienna

Public display boards, electronic billboards, advertisement hoardings are seen almost everywhere these days. With what TriLite Technologies and Vienna University of Technology are proposing, these displays could become 3D and we could view them without the need of 3D glasses. The Austrian scientists and engineers have developed a sophisticated laser system that sends laser beams into different directions so that from different angles, different pictures are visible. The display resolution is so fine that the right eye see a different picture than the right eye, thus creating a 3D effect. The folks over at TriLite and TU Vienna have created the first prototype.


Even though the first design has only a 5x3 pixel resolution, the team is content that the design works and are now gearing up for their second prototype which will have a higher color resolution. Every single 3D-Pixel also know as “Trixel” is formed of lasers and a moveable mirror. The laser beams are directed by the mirror across the field of vision, while modulating the laser intensity to send laser flashes in various directions. This system is most suitable for huge billboards as the viewer must be positioned in a certain distance range from the screen to experience the 3D effect. The creator can set the range in which the 3D image can be experienced by viewers. If it's too short or too long, both eyes will receive the same image and hence only a normal 2D picture can be seen.


Instead of showing just two pictures, this advanced laser system can show hundreds of pictures. Therefore, when someone walks by the display, he can get a view of the displayed object from different sides, as if he is passing a real object. To make this work, the research team has created a new video format. Even though the system is capable of using the 3D format converted from the 3D cinema movies we see today, the team wants to use new footage created especially for their displays.

The team has taken care of the fact that the displays should be visible in bright sunlight outdoors so the display is developed to be very vivid. For now, the team is happy about the success of their project in such a short period of time. The second prototype should be completed by mid-2015 and a commercial launch can be expected in 2016.
