A team of Austrian scientists is working on a laser system and has almost accomplished the task that will make this possible very soon.

The laser system sends laser beams into different directions and so various pictures are visible from different angles.

The angular resolution is so fine that the left eye is presented a different picture than the right one, creating a 3D effect, researchers said.

In 2013, a start-up company TriLite Technologies had the idea to develop this new kind of display, which sends beams of light directly to the viewers' eyes.

A new invention could let us build billboard sized 3D displays where different pictures can be seen at different angles, creating 3D effects without the need for 3D glasses.

The highly interdisciplinary project was carried out together with the Vienna University of Technology (TU Vienna).

TriLite and TU Vienna have now created the first prototype. Currently it only has a modest resolution of five pixels by three, but it shows that the system works.

To experience the 3D effect, the viewer must be positioned in a certain distance range from the screen. If the distance is too large, both eyes receive the same image and only a normal 2D picture can be seen.

The range in which the 3D effect can be experienced can be tuned according to the local requirements.
