It's quite common for the touch panel to run at 2x the display refresh rate. Eg, 120hz touch panels have been quite common for years on phones despite the 60hz disply.

It helps both slightly with latency directly, but it also gives you more points to sample from for input prediction which then helps with latency even more. Or for things like drawing applications it'll give you smoother curves assuming the drawing app looks at all intermediate touch samples.
