Abstract
An electronic device and a touch display panel of the electronic device are provided. The touch display panel receives a touch driving signal and generates a sense signal in response to the touch driving signal, wherein the sense signal is analyzed to calculate a touch position on the touch display. The touch display panel includes a transmitting circuit and a grounding electrode. The transmitting circuit distributes the touch driving signal in the touch display panel. The grounding electrode is disposed over the transmitting circuit and at least partially covers the transmitting circuit, wherein the grounding electrode is a grounded conductor.
