Display device

A display device, comprising:

• a control portion;
• a display panel comprising one or more pixel circuits and an image signal line connected to the pixel circuits;
• and
• an image signal line driving circuit,
• wherein the control portion comprises:
• a difference acquiring circuit for acquiring difference data between a value of a gray-level potential, which is to be applied to one of the pixel circuits from the image signal line, and a value of a precharge potential based on the gray-level potential;
• and
• a time-division transmitting section for transmitting the value of the gray-level potential and the difference data in sequence to the image signal line driving circuit, and
• wherein the image signal line driving circuit comprises:
• a time-division receiving section for receiving the value of the gray-level potential and the difference data from the time-division transmitting section;
• a calculating section for calculating the value of the precharge potential based on the value of the gray-level potential and the difference data received by the time-division receiving section;
• and
• an image signal line output section for supplying the image signal line with the precharge potential and the gray-level potential in sequence based on a calculation result of the calculating section.
