Samsung's Galaxy Gear smartwatch released last month has a flat screen, but the company is hoping to have the technology to make more attractive and wearable devices in what is shaping as a key battleground for consumer electronics companies.
Technology firms have yet to figure out how to cheaply mass produce the parts and come up with display panels that can be thin and heat-resistant. Batteries also have to take new forms to support flexible screens that can be rolled out, attached to uneven surfaces or even stretched. The battery in the Galaxy Round is not curved, Samsung said.
