Samsung is reportedly upgrading smartphone screens to 2K and 4K

Samsung has reportedly confirmed that it's working on smartphone displays not just in the 2K range, but all the way up to 4K resolution.

This news comes out of the South Korean Ministry of Trade, Industry and Energy's Semiconductor and Display Technology Roadmap Seminar 2014, as reported by Korea's media.daum.net.

Samsung's eventual adoption of 2K QHD 2560 x 1440 AMOLED smartphone displays comes as no shock, but it is somewhat surprising that the company would mention Ultra HD 4K phone displays this early.

The 2K screens could debut as soon as Samsung's Galaxy S5, which is expected to be announced soon - though that's pure speculation.

The future looks dense

Late in 2013 Samsung was rumored to be working on 4K smartphone displays that would debut in 2015, but 4K phones could be even farther off than that.

As G for Games points out, on a 5 inch display a 4K resolution of 3480 x 2160 equals a pixel density of roughly 820 ppi, and that's a lot of pixels.

But with even 2K smartphone displays still little more than a glimmer in most manufacturers' eyes, it will likely be a while before we learn about whatever meager advantages jamming so many pixels into so small a space could possibly produce.

Samsung also discussed future TV plans at the event, mentioning AMOLED TVs with UHD SHD 7680 x 4320 screens.
