Anyone who travels frequently and would like to have a second mobile display should be interested in the new Kickstarter campaign by the Chinese company Taihe, which is currently experiencing a small hype. The company is planning to produce a mobile display that comes with Full HD and USB Type C will cost just 160 dollars.

There is already vinpok split or asus mb16ap if you need built-in battery so why such hype?
This isn't really a new project, there are tons of these similar screens on Taobao, I'm surprised that *none* of them are available to the rest of the world?
