摘要： A display device includes a display unit comprising a plurality of pixels. A touch sensing unit is disposed on the display unit and comprises a plurality of driving electrodes and a plurality of sensing electrodes. A touch driver supplies a touch driving signal to the driving electrodes through a plurality of driving lines and receives a touch sensing signal from the sensing electrodes through a plurality of sensing lines. During a first horizontal period of one frame period, the touch driver supplies a touch driving signal having a first pulse width to a first partial portion of the driving lines and supplies a touch driving signal having a second pulse width smaller than the first pulse width to a second partial portion of the driving lines that is different from the first partial portion of the driving lines.

摘要： An input sensing unit may include the following elements: a first sensing electrode including first sensors and a first connector coupling the first sensors; a second sensing electrode including second sensors and a second connector coupling the second sensors; a first sensing line including first sensing line parts and a third connector coupling the first sensing line parts; a second sensing line; and an insulating layer including a first insulating side and a second insulating side opposite the first insulating side. The first sensing line parts may overlap the first sensors and may be disposed on the first insulating side. The second sensing line may overlap the second sensors and may be disposed on the first insulating side. The first sensors may be disposed on the second insulating side. The second sensors may be disposed on the second insulating side.
