TriLite intros glasses-free 3D digital signage displays and RGB laser modules for pico projectors

TriLite Technologies launches new laser display technology enabling glasses-free 3D outdoor displays and a new ultra-small RGB laser module for use in pico projectors.

Vienna-based TriLite Technologies, an image display company developing technologies for glasses-free 3D screens for outdoor digital signage, as well as fully miniaturized RGB laser modules for use in pico projectors, today announced development of their two products, the TriLite Trixel and the TriLite RGB laser module, respectively.

Both products will be demonstrated at the Photonics West 2015 exhibition, Feb. 10-12 in San Francisco.

"We are taking the next step in the evolution of large-scale outdoor digital signage screens by enabling viewers to see the screen's images in 3D, all this without having to wear 3D glasses," TriLite CEO Ferdinand St. Julien said in the announcement.

TriLite Trixel for glasses-free 3D: Each pixel contains a red, a green and a blue laser diode instead of LEDs currently used in large-scale outdoor screens as well as a movable micro-mirror, the company said. These so-called Trixels open up the possibility to steer different image information to the viewer's left and right eye, thereby enabling 3D without glasses for thousands of viewers. "Imagine, for example, the screens on New York's Times Square in 3D, or any setting that currently uses LED screens with full daylight viewability," St. Julien said.

TriLite RGB laser module for pico projectors: TriLite also developed a new approach to fully miniaturize pico projectors for use in devices such as smartphones, smart watches and smart glasses, the company said. "We have not yet seen embedded pico projectors in these devices mainly due to the large size of current RGB laser modules," said Dr. Franz Fidler, TriLite CTO. "While others are using complex and therefore large micro-optics, we are encasing a red, green and blue laser into one single hermetic package containing one single microlens."

This new approach reduces the size of the RGB laser module to just 9.1 x 5.5 x 5.3 mm and the weight to just 1.5 grams, making the light source extremely suitable for embedding in portable devices. Fidler said that "with the further reduction of size, TriLite's RGB laser module opens up the possibility of virtual reality smart glasses projecting image information directly into the wearer's eyes, and smartphones as well smart watches to feature embedded pico projectors."
