摘要： The present invention relates to a display device having a touch sensor in which the touch sensor is driven in a period which has a small noise component from the display device to reduce influence from the noise for minimizing a touch error; and a method for driving the same.The display device having a touch sensor includes a display panel, a panel driving unit for driving the display panel, a timing controller for controlling driving timing of the panel driving unit, a touch sensor integrated with the display panel attached thereto or built therein, and a touch controller for driving the touch sensor in a no noise period excluding a period in which the noise is generated periodically from the display panel by using at least one synchronizing signal from the timing controller, and calculating touch coordinates from a signal from the touch sensor and forwarding the touch coordinates.
