Abstract
Disclosed is a timing controller including a coordinate data generation circuit configured to generate X coordinate emission data for acquiring X coordinates and Y coordinate emission data for acquiring Y coordinates of touch coordinates, a selection circuit configured to time-divide 1 frame duration, to output the X coordinate emission data to a display driving circuit during an X coordinate field, and to output the Y coordinate emission data to the display driving circuit during a Y coordinate field, and a control data generation circuit configured to output control data for allowing each pixel to emit light in units of data line groups including i data lines using the X coordinate emission data during the X coordinate field and for allowing each pixel to emit light in units of gate lines including j gate lines using the Y coordinate emission data during the Y coordinate field, to the display driving circuit.
