Patent ID: 8188944

Claim:
A display device comprising: a pixel array part configured to include scan lines disposed along rows, signal lines disposed along columns, and pixels that are disposed at intersections of the scan lines and the signal lines and arranged in a matrix; and a drive part configured to drive the pixels via the scan lines and the signal lines, wherein the pixel includes at least a sampling transistor, a drive transistor, a hold capacitor, and a light-emitting element, a control terminal of the sampling transistor is connected to the scan line, and a pair of current terminals of the sampling transistor are connected between the signal line and a control terminal of the drive transistor, a current terminal of the drive transistor is connected to the light-emitting element, the hold capacitor is connected between the control terminal of the drive transistor and the current terminal of the drive transistor, the drive part has a scanner that sequentially supplies a control signal to the scan lines and a driver that supplies a video signal to the signal lines, in the pixel, the sampling transistor is turned on in response to the control signal to sample the video signal and write the video signal to the hold capacitor, and a current that flows through the drive transistor at the time of the writing of the video signal is subjected to negative feedback to the hold capacitor from the current terminal of the drive transistor to carry out correction for mobility of the drive transistor, and a drive current is supplied from the drive transistor to the light-emitting element depending on a corrected video signal following the correction, the driver switches a potential of the signal line from a reference potential to an intermediate potential before switching the potential of the signal line to a signal potential of the video signal, for the writing of the video signal to the hold capacitor, and the scanner supplies a first control signal pulse to turn on and off the sampling transistor when the signal line is at the intermediate potential, and then supplies a second control signal pulse to turn on and off the sampling transistor when the signal line is at the signal potential, wherein said intermediate potential is different from said reference potential and said signal potential, and said intermediate potential is between said reference potential and said signal potential.
