Abstract: A display device with a panel for preventing a light leakage is disclosed. The display device with the panel includes a display panel including an active area, on which information is displayed, and a first light shielding area positioned outside the active area and a panel disposed on the display panel. The panel includes a touch area having a size wider than the active area, a second light shielding area positioned outside the touch area, and a third light shielding area ranging from a start position of the first light shielding area to a start position of the second light shielding area. At least one dummy pattern is disposed in the third light shielding area of the panel.

Abstract: A touch sensing system and a method for driving the same are disclosed. The touch sensing system includes a touch screen including touch sensors and a touch sensing circuit applying a driving signal to the touch sensors. The touch sensing circuit applies at least one first driving signal to a first position of the touch screen and applies at least one second driving signal to a second position of the touch screen. When RC delay of the first position is less than RC delay of the second position, at least one of a width and a voltage of the second driving signal is greater than the first driving signal, or the number of second driving signals is more than the number of first driving signals.
