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.

Hey @alihaghighi, as stated in the Apple website, here are the display specs for the iPad Air 2:
9.7-inch (diagonal) LED-backlit Multi-Touch display with IPS technology
2048-by-1536-pixel resolution at 264 ppi
Fingerprint-resistant oleophobic coating
Fully laminated display
Antireflective coating
-As stated above the resolution is 2048×1536 pixels at 264 pixels per inch.
-Let me know if this helps.

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