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 the touch coordinates, a selection circuit configured to time-divide 1 frame duration, to output image data to a display driving circuit during a display field, to output the X coordinate emission data to the 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 generate source control data and gate control data for outputting the image data, the X coordinate emission data, and the Y coordinate emission data to a display panel and to output the source control data and the gate control data to the display driving circuit.
