Wireless Touchdisplay

[LePips]

This might be something strange to ask but does anyone know of wireless touch displays (preferably with battery)?

The idea is to bring it as an addition to a laptop.

I got the idea looking at the Asus portable monitors, which need a USB connection for both power and video signal.

Wireless will introduce some latency- it would make using the screen feel slightly sluggish as response times will increase and feel much more noticeable in a touch screen scenario when you expect 1 to 1 response with each action. I'm sure they do exist, but it sounds like it might be a bit of a hassle with very little benefit.
