摘要：

The present embodiments relate to a touch display device, a touch driving circuit, and a touch sensing method, and more particularly, when an event occurs in which a first area corresponding to a partial area of a touch screen panel is used as a touch sensing area, while a touch driving signal is output to a touch electrode positioned corresponding to the first area during a touch sensing period, The touch electrode positioned corresponding to the second region except the first region receives a signal different from the touch driving signal or is electrically opened, so that when only a partial region of the screen of the touch display device is a touch sensing region, touch sensitivity is reduced by the other region can be prevented.
