Display device and driving method of the same

A display device comprising:

• wirings for image data;
• a display controller connected to one end of the wirings for image data;
• and
• a source driver that is connected to the other end of said wirings for image data and generates a drive signal based on the image data sent out to said wirings for image data;
• wherein said display controller adjusts the frequency of said image data according to the display mode of the image,
• wherein said display controller comprises:
• a mode register that outputs a control signal according to the display mode of an image, and
• a timing control circuit that sequentially outputs said image data by a frequency adjusted based on said control signal and outputs a receiver control signal showing said display mode of the image, and said source driver generates the drive signal based on said display mode of the image that said receiver control signal shows.

A display device comprising:

• wirings for image data;
• a display controller connected to one end of the wirings for image data;
• and
• a source driver that is connected to the other end of said wirings for image data and generates a drive signal based on the image data sent out to said wirings for image data;
• wherein said display controller adjusts the frequency of said image data according to the display mode of the image,
• wherein a pair of or plural pairs of said wirings for image data are provided, said display controller has an image data switching control circuit that connects either one of each pair of said wirings for image data to a reference potential terminal and sets the other one to a floating state based on the image data, and said source driver generates a pair of or plural pairs of complementary current signals based on said image data by allowing the electric current to flow in the wiring connected to said reference potential terminal out of said wirings for image data, generates the drive signal based on the current signals, and controls the magnitude of the electric current allowed to flow in said wirings for image data according to said display mode of the image that said receiver control signal shows.
