Patent ID: 8648785

Claim:
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 wherein the image signal line driving circuit comprises: a calculating section for calculating the value of the precharge potential based on the value of the gray-level potential and the difference data; 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, wherein the display device further comprises: a plurality of first wiring lines for transmitting the difference data to the image signal line driving circuit from the difference acquiring circuit; and a plurality of second wiring lines for transmitting the value of the gray-level potential to the image signal line driving circuit from the control portion, wherein the difference data comprise a sign data indicating a sign of the difference between the value of the gray-level potential and the value of the precharge potential and the differential data indicating an absolute value of the difference; and wherein the plurality of first wiring lines are smaller in number than the plurality of second wiring lines.
