Glasses-free 3D TV and the connection to mobile

I am tracking the progress and commercial availability of glasses-free 3D TVs as I am not a believer in using glasses when consuming entertainment. I still pause at the TV section of my favorite electronics stores and check out the latest 3D TV that arrived to town that require glasses from different kinds. I also checked out the latest and greatest 3D TVs at CES and yes the quality is pretty good but you know that it requires that accessory on your nose which doesn’t feel like home entertainment to me.
I already blogged a bit about using 3D displays in cellphones using stereoscopic display as this is becoming a reality, see here 3D is real. Smartphones using 3D displays and 3D enabled camera configuration will become more popular as they are easy to use and true to the statement “anywhere, anytime”. However Glasses-free 3D DTV is a different story.
Toshiba rolled out small screen < 20” 3D displays without glasses and promised they’ll roll out a larger screen >40” 3D TV within the next 12 months. I guess Toshiba and other DTV makers predict that Glasses-free 3D TV will set demand soaring and mark the transition to 3D content consumption.

Here’s a nice video from Toshiba showing their latest 3D Monocle. Is that what we mean by glasses free 3D TV?

What’s the connection to mobile electronics?
3D viewing is already here and with glasses-free technology TVs will probably cross the chasm of market adoption seeing expedited adoption. Since TVs are the center of home entertainment they expect to have many features just like a hub for home entertainment and content consumption. Wireless connectivity added to TVs will enable not only browsing and internet-TV but making web calls. For that you need an image sensor for 2D capture or even capture. What’s better than talking to your parents or kids while sitting in the living room and viewing them in 3D? This will truly make the world closer, giving consumer total experience (just without touching).
Image sensors adopted in mobile will find their way to TVs in the near future and expected to become a standard feature in wirelessly connected TVs. These image sensors are similar sensors used today in smartphones which allow low power and high performance interface.
See diagram here that shows common configuration between SoC and image sensor utilizing MIPI CSI-2 protocol and D-PHY as well as CCI interface for camera control:

Image sensors could proliferate to other applications and not only DTVs. I’ll discuss migration of mobile electronics trends to other segments in one of the coming posts. Do share with me your thoughts.
