Driving method, touch sensing circuit, display panel, and touch display device
Abstract:
Discussed are a driving method, a touch sensing circuit, a display panel, and a touch display device in which touch driving of driving touch electrodes using a multi-frequency driving method while modulating a frequency of a touch driving signal of a pulse type. The touch driving signal drives at least one touch electrode and senses a touch or a touch position in touch sections for a touch mode. Each of the touch sections for the touch mode includes k or more unit touch sections. The frequency of the touch driving signal output in at least one unit touch section is different from the frequency of the touch driving signal output in another unit touch section. Accordingly, it is possible to enable touch sensing and to suppress an EMI phenomenon which may occur due to the touch driving signal.
