Abstract
Provided is a display device including: a display panel including a cathode layer including a cathode electrode, and touch electrodes including a touch driving electrode; a touch driving chip electrically connected to and providing a touch driving signal to the touch driving electrode; and a signal conversion unit electrically connected to a first electrode and providing a first driving signal to the first electrode. During the charging period, the touch driving signal is charged from a first level to a second level, and the first driving signal is charged from a third level to a fourth level. During the discharging period, the touch driving signal is discharged from the second level to the first level, and the first driving signal is discharged from the fourth level to the third level. The first electrode is the cathode electrode, or located between the touch driving electrode and the cathode electrode.
