Are Mobile 3D TV Models The Future Of 3D Entertainment?

With the debut on the markets of the LG Optimus Smartphone (known as the Thrill 4G in the USA) and the Nintendo 3DS 3D portable game console, mobile 3D TV has presented itself as an answer to the pricing and quality issues that larger screen 3D TVs have experienced, especially in the 3D TV without glasses arena. It's widely perceived that the 3DS - if successful - will drive the general popularity of 3D TV and associated 3D content.

LG unveiled their 4.3 inch display LG Optimus 3D Smartphone at the 2011 Mobile World Congress, the first mobile phone to have the capability to record, view, and share 3D content. The phone achieves recording via two 5.0 megapixel cameras, and can show 3D content via a display that gives video resolution of up to 1080p for 2D and 720p for 3D.

LG are now following up with the demonstration of a 7 inch mobile 3D TV that doesn't require glasses to see the 3D imaging, with plans for the prototype model to be seen at the 2011 NAB show in Las Vegas. The model uses a parallax barrier 3D LCD display, and features a built in antenna, 800 x 480 resolution, and of course can also receive and display standard 2D mobile broadcasts. 

At this stage, large display no glasses TV models of sufficient quality and at an affordable price are some way off general availability. Mobile 3D TV models have the advantage of small screen displays which give more effective 3D imaging capability, hence the reason why Toshiba's first released without glasses models were 20 inch sets. Smaller screen TVs are intended for single person viewing, hence lend themselves more effectively to the individual user requirements that without glasses 3D TVs present.

The reason for this is that no glasses 3D TV works using specific 3D TV technology that is based on how the displays
themselves emit the 3D images.

Normally the 3D displays that work with glasses send the 3D images by emitting two image sets, one for each of our eyes, which then synchronize with the glasses. In a no glasses solution the panel or display itself has to do the job of the glasses, and basically this means that for a larger display there are only a certain number of sweet spots where you'll get the 3D effect. This problem is far less apparent on a smaller mobile 3D TV display where your eyes are only 30-50cm from the screen, which makes the display of 3D images much easier to achieve.

The other benefit of mobile 3D TV will ultimately be in cost - in theory all that's needed is double resolution coupled with high brightness and a simple parallax barrier display.

That said, mobile 3D TVs from the major manufacturers are still in development phase, with early prototype models also experiencing some loss of 3D quality when you move off centre away from the sweet spots. LG demonstrated their mobile 4.3 inch parallax barrier 3D TV display at CES 2011. The display works by utilising a series of slits attached to the front of the LCD panel which act by blocking the light source at different times. This ensures that the left and right eyes of the viewer see the different images required to create the illusion of depth. Overall the reported 3D effect and quality was good.

The Japanese Company Ortus Technology, who are the makers of worlds smallest HD TV, have demonstrated a high quality small screen 3D TV.  The new 4.8 inch 3D HD TV works using the same technology as the HD model but upgraded to deliver 3D images. The LED backlit TV offers stunning quality 2D HD pictures at a pixel density of 458ppi and can display over 16 million colours. It delivers 3D images through the use of a special covering over the display equipped with the Ortus technology known as Xpol. This covering gives the panel the ability to display the alternate images required for us to see in 3D.

There is one manufacturer - Michley Tivax - who look to be more advanced on the mobile 3D TV front. Michley Tivax unveiled several innovative products at CES 2011, including two new mobile 3D TV devices. The first of these was a 7 inch portable no glasses 3D TV labelled the MiTV3D7, offering an 800x480 resolution LCD display. The second was certainly an interesting innovation, the MiTV 3D C201 dongle which lets users watch 3D content on a PC. The dongle couples with an antenna to give a solution that receives and displays a 2D or 3D program, though 3D glasses are required.

Aside from imaging quality, the benefit of 3D TV on mobile devices is fairly obvious - TV on the go and wherever you want it, with the added fun of 3D too. I can see it being particularly popular on journeys, where the portable DVD player now leads the field.
