Patent ID: 7639215

Claim:
A display comprising: a video signal line; a current source outputting a video signal, a first reset signal, and a second reset signal; pixels arranged along the video signal line and each comprising a drive circuit which is connected to a first power supply terminal and outputs a drive current at a magnitude corresponding to a magnitude of a first input signal, and a display element which includes a pixel electrode, a counter electrode connected to a second power supply terminal, and an active layer interposed therebetween; and a precharge circuit connected to a third power supply terminal and outputting a reset current at a magnitude corresponding to a magnitude of a second input signal, wherein the display is configured to execute a first reset operation during a blanking period, second and third reset operations and a write operation during each selection period, and a display operation during each non-selection period, the first reset operation including connecting the current source to the precharge circuit via the video signal line and writing the first reset signal as the second input signal into the precharge circuit, the second reset operation including connecting the current source to the drive circuit via the video signal line and writing the second reset signal into the drive circuit to set a potential of the video signal line at a first potential, the third reset operation including disconnecting the video signal line from the current source and making the precharge circuit output the reset current as a third reset signal to the video signal line for a given length of time to shift the potential of the video signal line from the first potential to a second potential, the write operation including connecting the current source to the drive circuit via the video signal line and writing the video signal as the first input signal into the drive circuit, and the display operation including connecting the drive circuit to the pixel electrode to make the drive current flow through the display element.
