DISPLAY HAVING TOUCH SENSOR AND TOUCH DATA PROCESSING METHOD THEREOF

摘要

PURPOSE: A display device including a touch sensor and a data processing method thereof are provided to increase an operation speed by reducing the amount of data to be operated. CONSTITUTION: A Tx operating circuit(302) supplies a touch operating pulse to Tx lines and an Rx operating circuit(304) receives a voltage of sensor nodes through the Rx lines to sample the node voltage and converts the sampled node voltage to generate data. A touch controller(400) binarizes the data and extracts a touch area based on the data. The touch controller performs a touch operation of the data in an operation block after differentiating sizes of operation blocks in order to grant touch labeling and to calculate a touch coordinate value.
