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.

Abstract: A display device includes a main region, a bending region which is bent from the main region in a thickness direction of a substrate, a sub-region which is connected to the bending region and faces the main region; and a plurality of wirings configured to extend from the sub-region through the bending region to the main region. The plurality of wirings includes: a first wiring to which a first voltage is applied; a second wiring to which a second voltage is applied; and a dummy wiring which receives a third voltage and is between the first wiring and the second wiring. The second voltage is higher than the first voltage, and the third voltage is less than the first voltage.

Abstract: The electroluminescence display device and the method of manufacturing the same are disclosed. The electroluminescence display device may include an on-cell type touch screen panel and a flexible printed circuit (FPC) for slimming down and cost reduction. It is possible to suppress cracks from being generated in the pad portion of the touch screen panel during film on glass (FOG) bonding by arranging the lower layer of the FPC at a certain distance away from the end of the touch screen panel.
