3D displays appear set for immediate improvement, after Hitachi unveiled a fresh 4.5in IPS screen for smartphones.

Unlike the Nintendo 3DS and HTC Evo 3D which both use parallax barriers to view a 3D effect, the Hitachi display touts a lenticular lens system. According to the company, this means brighter images and wider viewing angles.

The display - supposedly visible in direct sunlight - comes with a dot density of 326ppi and a resolution of 1280 x 720. Wowzers.

There's no official word on when these screens might take flight, but any improvement on current 3D tech is a welcomed one. We'll keep you posted. ®
