Samsung Electronics Co Ltd on Wednesday launched the world's first smartphone with a curved display, the Samsung Galaxy Round, a variant of the Galaxy Note which moves the Asian giant a step closer to achieving wearable devices with flexible - even unbreakable - screens.
Curved displays are on the frontlines of Samsung's innovation war with rivals such as Apple Inc and LG Electronics Inc, as the South Korean firm seeks to expand its lead in the slowing market for high-end smartphones.
"It's a step forward for having unbreakable gadgets and flexible devices eventually. But for now, the new phone is more of a symbolic product," said Hana Daetoo Securities analyst Nam Dae-jong, adding that Samsung did not yet have capacity for large-scale production of curved touch-screens for the new Galaxy Round.
The Galaxy Round is Samsung's attempt to gauge consumer appetite for curved phones although its lack of other eye-catching features means it is unlikely to be a hit, he said.
"I don't think it'll be massively compelling enough for gadget buyers as... the curved display doesn't come with many unique features," he said.
The Galaxy Round's 5.7-inch (14.4-centimetre) display has a slight horizontal curve and weighs less than the Galaxy Note 3, allowing a more comfortable grip than other flat-screen models on the market, Samsung said in a statement.
Its key features include a tilt function which allows users to check information such as missed calls and battery life, even when the home screen is off. Users can also scroll through media files by pressing the screen's right or left, the company said.
The phone initially would be available only in South Korea and no decision had been made about releasing it in other markets.
Curved displays open up possibilities for bendable designs that could eventually transform the high-end smartphone market, where growth has slowed amid competition from low-end producers.
Samsung's Galaxy Gear smartwatch released last month has a flat screen, but the company is hoping to have the technology to make more attractive and wearable devices in what is shaping as
