Trilite Large-scale Autostereoscopic Outdoor Displays
State-of-the-art glasses-free stereoscopic 3D displays are often limited in size, effective brightness, number of 3D viewing zones, and maximum 3D viewing distances, all of which are mandatory requirements for large-scale outdoor displays. Conventional autostereoscopic indoor concepts like lenticular lenses or parallax barriers cannot simply be adapted for these screens due to the inherent loss of effective resolution and brightness, which would reduce both image quality and sunlight readability.
TriLite Technologies (Vienna, Austria) is developing a modular autostereoscopic multi-view display with full sunlight readability and up to several thousand 3D viewing zones.
A Trixel Story
A first prototype has been developed by TriLite Technologies and TU Wien a few months ago. Each 3D pixel (called "Trixel") consists of a laser and a moveable mirror. The mirror directs the laser beams across the field of vision, from left to right. During that movement the image information is changed. With this basic idea, different pictures can be sent to the viewer´s left and right eye, so that a 3D effect is created without the need for 3D glasses.
