Abstract
Embodiments of the present disclosure relate to a touch display device, a touch driving circuit, and a touch sensing method, and enable differential sensing using a single-ended amplifier without using a differential amplifier, thereby not only accurately sensing a touch during display driving, but also significantly reducing the number of circuit components and the circuit area for differential sensing.
