Abstract:
A shift register provided to an in-cell touch panel, an image display including the same, and a method of driving the same. The shift register has a plurality of stages dependently connected to one another and includes first to nth stages dependently connected to one another in each of a plurality of block regions divided according to an image display period and a touch sensing period alternating plural times during each frame period; and first and second bridge stages disposed between each pair of adjacent block regions. According to the present invention, the shift register includes a plurality of bridge stages between each adjacent pair of adjacent stages among a plurality of stages divided according to an image display period and a touch sensing period to allow the plurality of stages to be driven in association with one another even during the touch sensing period, thereby preventing deterioration of specific stages. The shift register can prevent an abnormal screen such as a horizontal line defect in an image display panel, reduce a defect rate, and enhance customer satisfaction, thereby improving reliability of a product.
