NEW DELHI: Samsung is widely expected to use display panel with 2K resolution (2560x1440p) in its upcoming Galaxy S5. While the company's first smartphone with 2K resolution is still awaited, it has already started working on screens with 4K resolution.

At the Semiconductor and Display Technology Roadmap Seminar 2014 in South Korea, the company announced that it will unveil mobile displays with 2K resolution this year. This will be followed by 4K resolution screens in 2015.

2K displays offer twice as many pixels in the same area as HD screens (1280x720p), whereas 4K displays offer four times as many. Samsung has said that its mobile screens will offer pixel density of 820ppi, nearly twice that of the current crop of full HD displays.

In November last year, Samsung announced that it will launch handsets with bendable screens in 2014 and foldable screens by 2016-17. It has already shown a prototype of such a display, called Youm, at Consumer Electronics Show 2013. The company is also the first in the world to launch a smartphone with curved screen.
