Claim:
1. A liquid crystal display integrated with a touch sensor, the display comprising, a first substrate including pixels, the pixels connected to gate wires and data wires; a second substrate facing the first substrate; a plurality of common electrodes corresponding to the pixels; a plurality of sensing electrodes on the second substrate; a liquid crystal layer between the first substrate and the second substrate; a controller to generate a gate control signal; a gale driver to receive the gate control signal from the controller, to generate a gate signal based on the gate control signal, and to supply the gate signal to the pixels through the gate wires; a common electrode driver to generate a touch driving signal and to supply the touch driving signal to the common electrodes during a touch driving period, wherein: the controller supplies the gate control signal being synchronized with the touch driving signal to the gate driver during the touch driving period, the gate control signal includes at least one clock signal in the touch driving period, the at least one clock signal has a pulse width that is an integer multiple of a pulse width of the touch driving signal, and the at least one clock signal has a first width size in a display period, and has a second width size different from the first width size in the touch driving period, and wherein the second width size is adjusted from the first width size such that edges of the at least one clock signal arc synchronized with edges of the touch driving signal.
