Glasses-free 3D displays

Technical Q&A with Maarten Tobias from Dimenco

DA: What is the biggest technical obstacle to glasses-free 3D?

Glasses-free 3D displays have had 3 main obstacles to overcome.

1) Resolution: By applying a lenticular layer to generate multiple views on top of a LCD panel you lose a significant amount of resolution. The result was that with "traditional" FHD panels (1920 by 1080) you experienced, depending on the lens design and image processing, a SD image quality in 3D. With the introduction of QFHD panels (3840 by 2560) it is possible to overcome this problem as you can realize with the right lens design and image processing a FHD 3D picture. This FHD 3D image is impressive to watch and provide the "right" consumer experience.

2) Cone transitions: Traditional auto-stereoscopic displays always had annoying cone transitions. This means you have to be in the right zone for a comfortable 3D experience. With the recent introduction of smooth cone transitions by Dimenco it solves almost completely the cone transition which makes it much more comfortable and enjoyable to watch glasses-free 3D for a long period of time.

3) Content: Glasses-free 3D displays depend on multiple perspectives that are "sent" out to the viewer. Meaning stereo 3D (with glasses) is based on a left and right picture (2-view) which provides the necessary parallax. Glasses-free 3D displays require multiple perspectives, in Dimenco’s case 28, which has to be generated. Dolby3D, an initiative by Philips and Dolby, is integrating algorithms that will make it possible to convert in real-time stereo (2-view) to auto-stereo (n-view), resulting in overcoming the barrier of existing 3D content becoming available for glasses-free 3D.
