Leading smartphone developers are constantly working hard to create new innovative screens. LG engineers have also made a contribution by registering a patent for an unusual screen with a huge diagonal. The company has already created a folding TV, and now the developers have taken up small smartphones. The National Patent Office – Korea Intellectual Property Right Information Service (KIPRIS) has registered a roller smartphone screen patent.
The technical documentation of the patent describes the invention as a device with a screen having a large diagonal and four pairs of swivel joints, necessary for rolling the screen. In a minimized state, the screen wraps around the case several times, and the remaining part of it can function as a standard smartphone. When unrolled, the screen area is comparable to or even larger than a tablet screen.
The developers claim that the device can also work with a partially unrolled display. Depending on the need, the user will be able to unroll the monitor to the required size, and the system will get adjusted to the open area.
