See-through screens, phones that wrap around your wrist, expandable displays and smart rings – just some of the products on display at the Mobile World Congress in Barcelona
Samsung ring
Samsung’s Galaxy Ring, its latest wearable, is launching with health-tracking features including heart rate and sleep monitoring.
These are all concept tech that gadget makers showed off this week in a bid to stand out from competitors.
At the Mobile World Congress in Barcelona, companies from Lenovo to ZTE showed off displays for their devices.
ZTE 3D display
ZTE showed off a second-generation tablet that displays three-dimensional images. Typically, 3D images have required some sort of glasses to view, as is the case with 3D movies in theatres.
But this screen produces a 3D image without glasses.
Lenovo see-through screen
China’s Lenovo showed a prototype of a laptop with a see-through display.
The company, which is the world’s largest PC maker, showed how an object can be placed behind the screen and detected by the device’s cameras. Information about the object would be displayed on the screen.
