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, 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 pixels connected to one data line to emit light in units of 1 data line using the X coordinate emission data during the X coordinate field and allowing pixels connected to one gate line to emit light in units of 1 gate line using the Y coordinate emission data during the Y coordinate field, to the display driving circuit.
