Now, a report tips that the South Korean giant has plans to start mass-producing 5.9-inch Ultra HD (4K) Super AMOLED display boasting of a pixel density of 700ppi for August next year.
Phone Arena points out that the rumoured August manufacturing time frame for the new UHD Super AMOLED displays goes in-line with Samsung's annual Note phablet release, suggesting the alleged 5.9-inch UHD (2160x3840 pixels) display will be meant for the Galaxy Note 4 successor.
As of now, the details about the rumoured 5.9-inch Ultra HD Super (4K) AMOLED display are limited and there is no word from Samsung as well.
The South Korean giant early this year at its Semiconductor and Display Technology Roadmap workshop hinted that it was working on a QHD (Quad-HD, i.e. 2K) Super AMOLED mobile display panel with a massive 560ppi pixel density - something the Motorola recently achieved with the Droid Turbo or Moto Maxx.
It was then also said that Samsung had an even better display under works, to be specific, a UHD (Ultra-HD, i.e. 4K) display, with a 2160x3480 pixel (4K) resolution, along with a crazy 860ppi pixel count that would be stuffed in a sub 5-inch display size.
LG last month announced that it developed a 5.3-inch full-HD LCD panel for smartphones sporting what it claimed was "the world's narrowest bezel at 0.7mm".
