Abstract
An exemplary embodiment of touch display device includes a touch panel and a signal processing circuit. The touch panel includes a plurality of touch sensing units, and each touch sensing unit includes a touch sensing element and a coupling sensing element. The signal processing circuit is electrically connected to the touch sensing element and the coupling sensing element. The touch sensing element provides a touch signal to the signal processing circuit, the coupling sensing element provides a coupling signal to the signal processing circuit, and the signal processing circuit processes the touch signal according to the coupling signal to filter an interference signal of the touch signal. A touch display device using the touch panel is also described.
