How Shenzhen helps Royole Corp shine at the global level

If the startup's flexible displays are taking the electronics world by storm, much credit is due to the southern city that has what Silicon Valley doesn't have

Shenzhen-based Royole Corp made a splash during its first appearance at the Consumer Electronics Show in Las Vegas in January.

It demonstrated a thin, rollable and transparent keyboard that is concealed within a speaker and charging station when not in use. The keyboard can be pulled out for heavy-duty typing on smartphones. Another star was a sleek, smooth and curved electronics-enabled car dashboard free of buttons.
