Abstract

Disclosed is a timing controller including a coordinate data generation circuit configured to generate X coordinate emission data for each data line group and Y coordinate emission data for each gate line group, a selection circuit configured to output the X coordinate emission data during an X coordinate field and to output the Y coordinate emission data 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 the data line groups based on the X coordinate emission data during the X coordinate field and allowing each pixel to emit light in units of the gate line groups based on the Y coordinate emission data during the Y coordinate field, wherein the X coordinate emission data for each data line group and the Y coordinate emission data for each gate line group have random color.
