Sony revitalizes smartphone franchise with movie-ratio screens

Sony, the Japanese company that has fallen way behind its Korean and Chinese rivals in the smartphone sales race, is aiming to capitalize on its movie pedigree with new devices featuring 21:9 ratio screens, the dimensions used to film blockbusters.

The company announced a new flagship Xperia One handset, which has a HDR OLED screen, optimized using its Bravia TV technology, and the ability to take photos and record 4K video in a 21:9 ratio, at the Mobile World Congress on Monday.
