Abstract
A display executes a first reset operation during a blanking period, and second and third reset operations and a write operation during each selection period. The first reset operation includes connecting a current source to a precharge circuit and writing a first reset signal into the precharge circuit. The second reset operation includes connecting the current source to a drive circuit of a pixel and writing a second reset signal into the drive circuit to set a potential of a video signal line at a first potential. The third reset operation includes disconnecting the video signal line from the current source and making the precharge circuit output a reset current 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.
