Abstract
A display device is provided with a display controller, a source driver, and a liquid crystal panel, and two pairs of wirings are provided between the display controller and the source driver. The display controller is provided with a V-I conversion circuit for image data and a mode register, and the source driver is provided with an I-V conversion circuit for image data. The V-I conversion circuit for image data connects either one of a pair of the wirings to an earth electrode and sets the other one to a floating state based on the image data. The I-V conversion circuit for image data allows electric current to flow in the wiring out of a pair of the wirings, which is connected to the earth electrode, and converts the image data into a pair of complementary current signals to receive them. Further, the I-V conversion circuit for image data stops the current signal by a control signal from the mode register when the image data is not transmitted.
