Abstract

A touch control device with ESD protection includes a touch display panel, a switching unit, a touch electrode and a ground electrode. An ESD protection electrode is provided around at least one periphery of the touch display panel. A scanning period of the ESD protection electrode is divided into touch periods and ESD periods. When the scanning period of the ESD protection electrode is during the touch periods, the ESD protection electrode is used as touch electrodes for sensing touch events made by a user on the touch display panel. When the scanning period of the ESD protection electrode is during the ESD periods, the ESD protection electrode is used as ESD protection electrodes for dissipating ESD on the touch display panel in order to protect signal elements inside the touch display panel. The ESD protection electrode is therefore used for not only ESD protection, but also touch sensing.
