Don't know how it can call itself the 'first' to do so, since there was a few before this such as iDisplay but this claims to be “built by ex-Apple engineers, delivering a retina display at 60 frames per second with no lag. Seriously.” So could be worth checking out :)
It was the quote that caught me. Would love a 60fps iPad display
Seems to be wired, which could maybe be how it has no lag.
