London: A South Korean firm, Pantech, has unveiled the biggest smartphone with a screen capable of showing 1080p high-definition video at full resolution.
Pantech's Android-powered Vega No 6 features a 5.9 inches display, which packs in 373 pixels per inch.
According to the BBC, China’s Huawei recently unveiled a 6.1in handset, but it was only a 720p display.
They add to the so-called ‘phablet’ category, as manufacturers test how big customers are willing to go.
Dell had previously released a 5in phone, the Streak 5, but had ended up discontinuing the line to focus on a larger 7in tablet.
According to the report, in recent months other firms, including Sony, LG, HTC and ZTE, have unveiled smartphones with 5in and larger screens.
More super-sized handsets are expected to be announced at the Mobile World Congress in Barcelona which begins on 25 February, the report added.
