How precise is the iPad touch screen?

I was trying to do an experiment with my iPad Air 2 but I needed to know exactly how precise can the touch screen locate my finger? In other words, what is the resolution of the touch screen?

Thanks!

The touch resolution is 1024 by 768, however the sensor array is much less dense, only about 40 by 30 (my own guess). Detailed positioning is determined by reading the raw values of the sensors and calculate an averaged center of each touch signal.

Actually no. The touch resolution is different from display resolution.
