Marval Digital demonstrated glasses-free 3D displays for up to 65″ 4K 3D displays, and also for 3D phones and 3D tablets. The 4K 3D TV displays feature up to 140 degree viewing angles.
Marvel Digital also sells (price unknown) VisuMotion, a software tool for professional conversion of 2D video to 3D.
StreamTV Networks also showed new 360 degree VR technology, plus their glasses-free 3D technology. When I attended CES in the past, the StreamTV technology was the best glasses free 3D technology that I saw at the time.
