Display driving device, display device and operating method thereof

A display driving device comprising:

• a display panel comprising first and second pixel arrangement areas, each of the first and second pixel arrangement areas comprising a plurality of pixels arranged in areas in which a plurality of gate lines intersect a plurality of data lines;
• a data driving circuit comprising a first source driver circuit configured to output a first display data group to a data line of the first pixel arrangement area, and a second source driver circuit configured to output a second display data group to a data line of the second pixel arrangement area;
• a timing controller configured to array input data and configured to transmit output data to the data driving circuit at at least two preset transmission speeds corresponding to respective arrangement area from among the first and second pixel arrangement areas, the timing controller being configured to generate timing control signals;
• a gate driving circuit configured to receive one of the timing control signals and configured to drive the plurality of gate lines of the display panel;
• and
• a voltage generating circuit configured to generate voltages for driving the display panel,
• wherein the display panel is divided into the first pixel arrangement area and the second pixel arrangement area and based on the divided display panel, the first source driver circuit outputs the first display data group to the data line of the first pixel arrangement area and the second source driver circuit outputs the second display data group to the data line of the second pixel arrangement area, and
• wherein the timing controller transmits the output data at said at least two transmission speeds which are different from each other based on the divided display panel.
