Abstract: A display device having touch sensors includes a touch screen forming sensor nodes at crossings of Tx lines and Rx lines, a Tx driving circuit supplying a touch driving pulse to the Tx lines, an Rx driving circuit which receives voltages of the sensor nodes through the Rx lines, samples the sensor node voltages, and converts the sampled sensor node voltages into touch raw data through analog-to-digital conversion, and a touch controller which receives and binarizes the touch raw data, extracts a touch area based on the binarized touch raw data, differently sets a size of a computation block based on a position of the touch area and the number of touch areas, and performs a touch computation only on touch raw data of the computation block.
