Sony and Beijing show rise of services

In a marble-rich building beside the Fourth Ring Road in eastern Beijing, a group of engineers busily discussed the tech nitty-gritty of a gigantic display screen made of ultra high-definition light-emitting diodes.

Called the 4K x 2K LED screens, they showcase the latest imaging technology of Japan's Sony Corp.

The one to be installed in Beijing would be Sony's first-ever commercially available 4K x 2K LED screen of this kind. It will be used to screen advertisements, videos, entertainment, live television and other content.
