Lose The Glasses

LG Electronics has unveiled a new glasses-free 3D monitor which uses technology that could have great relevance for future digital signage applications. The display uses eye-tracking technology to maintain an optimal 3D image from a range of viewing angles.
 
The 20-inch D2000 monitor was developed as a fully functional entertainment display for the consumer market but the technological innovations could soon migrate to the digital signage industry.
 
Existing glasses-free 3D technologies generally require viewers to stay within a tightly restricted angle and distance to perceive the 3D images. However, the D2000 has done much to resolve this issue. Eye tracking in the D2000 works via a special camera sensor attached to the monitor which detects changes in the user’s eye position in real-time. With this information, the monitor calculates the angle and position of the viewer and adjusts the displayed image for the optimal 3D effect.
 
Up to now, the restricted viewing angles of autostereoscopic (glasses-free) 3D displays have been a barrier to their wider deployment in digital signage applications. The 3D effect was only perceivable from certain angles, so its potential for use digital signage applications, which often rely on catching the attention of passers-by who see the screens out of the corner of their eye, was limited.
 
The D2000’s 3D effect comes courtesy of glasses-free parallax barrier 3D technology, and the application of what developers claim is the world’s first eye-tracking feature to the monitor. LG says the combination of parallax barrier and eye-tracking in a single unit has the potential to open up new horizons for glasses-free 3D products. This could well include digital signage.
 
Si-hwan Park, Vice President of the Monitor Division at LG’s Home Entertainment Company. “LG’s position has always been that 3D will and must eventually function without glasses. The D2000 is a look at what the future has in store.”
