Patent ID: 7852297

Claim:
A display device comprising a plurality of pixels, each pixel comprising: a pixel electrode; a power supply line; a first circuit including a first switch and a first current source circuit wherein a first terminal of the first switch is electrically connected to the pixel electrode, a second terminal of the first switch is electrically connected to a first terminal of the first current source circuit and a second terminal of the first current source circuit is electrically connected to the power supply line; a second circuit including a second switch and a second current source circuit wherein a first terminal of the second switch is electrically connected to the pixel electrode, a second terminal of the second switch is electrically connected to a first terminal of the second current source circuit and a second terminal of the second current source circuit is electrically connected to the power supply line; a first line for supplying a first control signal to the first current source circuit; and a second line for supplying a second control signal to the second current source circuit wherein the first line is different from the second line, wherein the first circuit and the second circuit are connected to the pixel electrode in parallel.
