Smartphones are huge these days. There is no surprise that smartphone can pack a screen that’s as large as 4.5 inches. The AT&T’s Samsung Infuse is one of the few smartphones out there that offers a large 4.5-inch screen.

With the growing amount of multimedia data and 3D content, smartphones will definitely need a big screen, despite the major downside is they’ll be less pocketable.

To bring more 3D excitements to smartphones, Hitachi has readied a huge 4.5-inch glasses-free 3D IPS LCD display that’s even capable of pumping out at a super high-res of 720p i.e. 1280 x 720 pixels worth of resolution.

The Hitachi’s glasses-free 3D screen will be adopted by portable gadgets and smartphones. Unlike other glasses-free 3D displays used on Nintendo 3DS or the recently announced Sprint EVO 3D smartphone which use parallax barrier method, the Hitachi’s 3D display uses “liquid crystal lens system” that offers twice the brightness (Similar to the technology used on the Toshiba’s world’s first glasses-free 3D laptop). The image above shows a rudimentary example of how it works.

Now the debate lies between whether you need 3D screen for smartphones? Although the screen size can be as large as 4.5 inches but it’s still less comfortable or enjoyable while compared to viewing 3D videos on a larger 3D display, such as a 3D HDTV. However, playing 3D games on a 4.5-inch glasses-free 3D smartphone should be as exciting as playing them on a Nintendo 3DS.
