Earlier this month, we have reported that Samsung is planning 64-bit 4K Ultra HD smartphones. While many of us were pretty skeptical about Ultra HD displays, it looks like the company is almost ready for mass production of high resolution 560ppi displays.

　　One of the rumoured smartphones to have such high resolution would be the Galaxy S5. While it is still too early to talk about the phone, having 560ppi display will definitely be one of the key features of the handset and with LG closing the gap with its WQHD (2560 x 1440 pixels) mobile displays, Samsung definitely needs to do something about it if they want to stay at the top.
