And recently a patent appeared indicating that Samsung is exploring other types of display screens for smartphones, including roll-up and slide-out screens.
Choi Kwon-young, vice president of Samsung Display, said: “Samsung is expanding its leadership in the foldable market through small and medium screens this year.
Young added that there is currently in the market foldable foldable and foldable screens, and Samsung is adopting new technologies first to expand its portfolio and customers.
Samsung is adopting technologies such as variable refresh rate and low power to respond to competitors entering the OLED market.
It is also seeking to enhance the benefits of OLED amid the rise of remote services caused by the Coronavirus pandemic, to be applied across more laptops, tablets and cars.
More smartphones use OLED screens, including the newly launched iPhone 12 series, in all of its models.
Young said: The first Samsung screens that rotate and slide is coming this year, so that Samsung’s mobile division is supposed to be the first to adopt these technologies, but this has not been explicitly confirmed.
In terms of large screens, Samsung is working to develop a quantum display QD in a timely manner and build a stable group of customers so that the technology can enter the premium sector.
The company also continues to provide LCD screens to customers upon their request, and Samsung Display was initially aiming to finish producing LCD screens in 2020, but it continues to manufacture them based on the requests of Samsung and other customers.
Samsung Display achieved its highest quarterly profit in the fourth quarter, thanks to the high demand for OLED smartphones and the increase in the average selling prices of large screens used in televisions.
The company reported sales of 9.96 trillion won and operating income of 1.75 trillion won in the fourth quarter.
For the whole of 2020, Samsung Display recorded about 30.59 trillion won and operating income of 2.24 trillion won, down 2 percent and an increase of 42 percent, respectively, from 2019.
Although there are no foldable smartphones on the market at the moment, it is not difficult to see why it is a more attractive concept than foldable phones.
Rollable screens, based on the currently proposed implementation, can allow phones to maintain a slim shape and outward appearance, while foldable smartphones tend to appear bulky.
