Samsung Planning Galaxy Smartphone With Three-Sided Display

The phone will use an upgraded version of Samsung’s technology called Youm, currently featured in the curved Galaxy Round handset, the people said, asking not to be identified because the plans haven’t been released. The display may be used in the S or Note series of premium handsets or may be the first in a new line, the people said. Samsung plans to have each side of the display operate independently.

The world’s largest maker of handsets is fighting with Apple to introduce innovative devices as they brace for a slowdown in the high-end smartphone segment, where Samsung sells about one of every three devices. Apple is developing new iPhone designs including bigger screens with curved glass and enhanced sensors that can detect different levels of pressure, a person familiar with the plans said Sunday.
