During the event Analyst Days in 2013, Samsung presented a slide which showed the progress of their AMOLEDs screens. At that time, the company was bringing to the market the Galaxy S4 which would be its first smartphone with Full HD screen, with 1920 x 1080 pixels, which results in a dimension of 441 dots per inch. In this same slide was possible seeing future business launches, with screens with higher resolutions and an estimated date for the same reach the market.
As you can see in the image below, was considered for that in 2014 we told with qHD screen (with a resolution of 2560 x 1440 pixels). This estimate was actually achieved with the Galaxy Note 4 and its 5.7-inch AMOLED screen that features 515 ppi. With the Galaxy S6, Samsung brought the same resolution and then offer a higher ppi with 577 points. During the presentation of his flagship, the South Korean made it clear that extending the resolution only brings benefits to users by offering an image more clearly.
With that in mind, it was expected that with the release of Galaxy Note 5 the company to bring even more pixels to overcome the 577 ppi of its current flagship. In the chart above we can see that the company expects this year already count on ready screen with 4K resolution (3840 x 2160 pixels offering). Since the event in 2013, Samsung never mentioned it, but according to a source close to the company, the South Korean is actually working on a Ultra HD panel which will come into mass production starting in August. With the announcement of Note 5 scheduled for September during the IFA 2015 , we can expect the news to be released on it.
The source also said that we will have two versions of phablet this year, as I expected. The traditional version of Note 5 will come with screen 5.89 inches , resulting in 748ppi. Have the Edge version, with similar design to the S6 Edge, will feature smaller screen 5.78 “ bringing a total of 762 dots per inch. This shows that Samsung really to be the pioneer in bringing so many pixels to the screen of a smartphone. What concerns us is the high consumption, especially when the batteries can not evolve as fast as other components for smartphones. Not to mention the use of a GPU capable of dealing with so many pixels, especially in games.
Does the Samsung is being hasty in bringing a 4K screen so soon to the smartphone market? Very few applications for Android that have been optimized for Quad HD screens, and onwards to the Ultra HD only make everything complicated. But apparently, companies are only concerned with chasing large numbers in an endless war for increasingly aggressive smartphones in terms of specifications.
