It is expected that a smartphone that folds, unfolds, and turns, and a smartphone that can be rolled up now will be released.
As the smartphone market saturates, manufacturers are struggling with innovative forms.

you pull the side of the smartphone to the right, the rolled up screen opens like a drawer.
This is a preview video of a rollable phone released by LG Electronics.
Samsung also unveiled a'slide smartphone' with a curling screen earlier this year, and it is expected to be released next year as soon as possible.
[Jangwoong Park/Professor, Department of Materials Science and Engineering, Yonsei University: It can be seen that foldables and rollables are technically similar, and the next direction will be a form that can be pulled.

form of a smartphone, the screen size has been increased and the border has been reduced, but it has maintained the'bar' type for over 10 years.

It is expected that the game will differ depending on how high-quality products are presented and overcome various technical difficulties that may arise in the process of rolling up the screen.
