Patent ID: 7119782

Claim:
A display device, comprising: a pair of or plural pairs of wirings for image data; a display controller that is connected to one end of said wirings for image data and outputs said image data by connecting either one of each pair of said wirings for image data to a reference potential terminal and setting the other one to a floating state based on the image data; and a source driver that is connected to the other end of said wirings for image data, generates a pair of or plural pairs of complementary current signals based on said image data by allowing electric current to flow in the wiring connected to said reference potential terminal out of a pair of or plural pairs of said wirings for image data and generates a drive signal based on the current signal when said display controller outputs the image data, and does not allow the electric current to flow in both of said wirings for image data when said display controller does not output the image data.
