Samsung confirmed that it is working on bringing Ultra HD 3840 by 2160 pixel technology to their upcoming mobile devices in 2015. The information was gathered based on the company's Analyst Days presentation slides.
During Samsung's Semiconductor and Display Technology Roadmap workshop held in 2014, the company hinted that a smartphone with higher-resolution UHD display is in the pipeline. Samsung had actually used the term "diamond pixel," which refers to a non-standard pixel matrix arrangement when referring to the technology.
Eventually, it was learned that Samsung is placing those UHD Super AMOLED displays in the upcoming Galaxy Note 5. Production of the displays is slated to begin in August and the device is for launch in fall 2015.
The Galaxy Note 5 will reportedly come in two versions: the 5.78-inch dual-edge model and the 5.89-inch regular variant with a flat display. Pixel densities are measured at 762 and 748 respectively.
Other notable features of the Galaxy Note 5 include an octacore Snapdragon 810 chipset, 4 GB of RAM, rear camera that can have 18 or even 21 megapixels, front camera with either 5 or 6 megapixels, storage options of 16 GB to 128 GB, 4000 mAh battery and up to 128 GB microSD support. Rumors also say that the Galaxy Note 5 may feature Samsung's own Exynos 7420 chipset.
The company's current Galaxy Note 4 features a 5.7-inch quad-HD Super AMOLED display with a pixel resolution of 2560 by 1440.
Some rival phone makers such as LG, hinted at creating smartphone displays with 600 ppi, but can even reach up to 700.
However, some experts tried to explain on the relevance of smartphone with higher-resolution displays. They say that the human eye can only perceive a certain amount of pixels.
"At around 12 inches from an object, a perfectly healthy human eye with 20/12 vision, which is even better than 20/20 vision, would be able to see 466 pixels per inch," says Daniel Gleeson, a senior analyst at IHS, on his interview by CNET.
The Galaxy Note 5 is speculated to have an informal launch in September at the 2015 IFA expo event. It is scheduled to land on store shelves in the fall, and its retail price will be somewhere between $800 and $890.
