Static Electricity on the Screen
Touch screen is easy to carry static in dry weather, which you may not be able to touch the screen. If this situation happens, you can either place you phone without phone case on the ground to discharge the static through the electrical ground, or wipe the screen with a wet cloth to eliminate the static.

Touch IC Malfunction
The malfunction of touch IC can also lead to the malfunction of screen, which commonly happens among iPhone 6. If this happens, the parts should be repaired or replaced.
