While only a small but growing number of users have even upgraded their desktop computer with a 4K monitor, a new report from PhoneArena claims that Samsung will start mass-producing a 5.9-inch 4K Ultra HD Super AMOLED display in August. Conveniently, that is around the time Samsung might begin manufacturing its Galaxy Note 5.
According to the report, the high-resolution display would have over 700 PPI, which would be an impressive accomplishment for a mobile screen. For comparison purposes, the just-announced Nexus 6, which also has a 5.9-inch display, has a 1440×2560 pixels resolution that is good for 439 PPI. Meanwhile, the 5.5-inch iPhone 6 Plus has 401 PPI.
Nevertheless, the rumor should be treated with a proverbial grain of salt given that PhoneArena is basing its report on one uncorroborated tip received from a source. A mobile screen with over 700 PPI would make it virtually impossible for users to distinguish between individual pixels with the naked human eye.
PhoneArena adds that LG Display claimed that mobile screens with 700 to 800 PPI are within reach earlier this year, while noting that Sharp is also reportedly working on its own 4K smartphone display.
