According to reports from South Korea, Samsung is working on an OLED display with an impressive pixel density of 1000 ppi. At the moment, it is said that it is not entirely clear if it is developing it for the mobile market, but it can be expected.
To achieve such a high density, Samsung is said to be developing a new TFT technology (Thin-Film Transistor; technology of thin-film transistors) for AMOLED panels. In addition to enabling such a delicate display, the company's future TFT technology should also be much faster than current solutions, namely up to 10 times. Samsung is also said to be aiming to make its future superfine display more energy efficient and cheaper to manufacture. How exactly it wants to achieve this is unclear, but a 1000ppi display should be available by 2024.
In theory, such a fine display would be great for VR headsets, but Samsung has not shown much interest in this area recently. However, 1000 ppi is the pixel density that Samsung's Gear VR division set as a goal four years ago - at the time it said that once VR screens exceeded 1000 ppi pixel density, all problems associated with motion sickness would be eliminated.
However, given Samsung's aforementioned lack of interest in virtual reality in recent years, it is likely that the new TFT technology will be deployed in future smartphones. Just to give an idea - the display with the highest pixel density at the moment has 643 ppi and is used by the Xperia 1 II smartphone (it is an OLED screen with a size of 6,5 inches).
