Which risk increases when a capacitive touch screen controller's parasitic capacitance variations exceed manufacturing tolerances?

💡 Explanation

When parasitic capacitance variations are excessive, the signal-to-noise ratio during touch detection decreases because the controller misinterprets noise as a touch, increasingly triggering erratic and spurious activations. Therefore, false touch events increase, rather than cracking, flickering, or increased latency, which arise from separate failure origins.
