We propose a capacitive touch sensor with a‐IGZO TFTs on plastic using pseudo‐CMOS inverter as output buffer. Benefit from the pseudo‐CMOS structure, the sensor achieves both high‐speed and large output swing between touched/untouched state. This result demonstrates a novel approach to large area flexible touch sensing applications.
