Of course the video is a little bit misleading when it talks about 1ms refresh, since touch response stops being the limiting factor before that point. AFAIK the fastest refresh rate for any phone on the market is 250Hz. That's 4ms refresh, which is great, but of course you also have to factor in time to actually process the touch event, change the image, and render it.

It's not misleading at all. They specifically said it was a test setup and stated that their aim is to be at around 1ms latency in the next decade. Obviously that means working on the other limiting factors to get there as well. It's not like they'll just try to get the touch response to 1ms and ignore screen refresh rates.

If we want a 60Hz app, the touch latency + processing + display shouldn't exceed 16.7ms.

1ms touch latency would be nice indeed, but I think 5-8ms would work just as well on most devices.
