The stretchable OLED display that Samsung Display introduced during Global Tech Korea 2021, which was held in early September, is 13 inches and is characterized by elasticity like a rubber material. In the video exhibited as a demonstration, the video of thick volcanic lava flows, but if you look closely, the screen is waving in line with the video. As you can see from the video, there is no damage like cracks on the screen.
The stretchable display serves to express a three-dimensional effect through elasticity. The biggest problem with foldable smartphones currently on the market is that they are easily broken or break when the screen is subjected to force. However, it can be expected that it can be significantly reduced by changing it to a stretchable display. Not only that, you can expect to use it in-game as well. Unlike controllers, touchscreen play lacks feedback. Care must be taken to ensure that the button displayed on the screen is properly pressed. However, if it is a stretchable display, it may feel as if you are touching the game screen buttons with your finger. Integrating the screen and controller can give you another pleasure.
