Display, array substrate, and method of driving display

An array substrate comprising pixel circuits and video signal lines arranged correspondently with columns which the pixel circuits form, each of the pixel circuits comprising:

• a drive circuit including a drive transistor whose source is connected to a power supply terminal, a switch group which switches a connection state between a first state that drain and gate of the drive transistor and the video signal line are connected to one another and a second state that the drain and gate of the drive transistor and the video signal line are disconnected from one another, and a capacitor which is connected between a first constant potential terminal and the gate of the drive transistor;
• a reset circuit including a reset transistor and a reset switch connected in series between a second constant potential terminal and the video signal line, a drain of the reset transistor being directly connected to a gate of the reset transistor or connected to the gate of the reset transistor via the reset switch;
• a pixel electrode;
• and
• an output control switch connected between the drain of the drive transistor and the pixel electrode.

A method of driving a display comprising pixels, video signal lines arranged correspondently with columns which the pixels form, and a video signal line driver to which the video signal lines are connected, each of the pixels comprising a drive circuit including a drive transistor whose source is connected to a first power supply terminal, a switch group which switches a connection state between a first state that drain and gate of the drive transistor and the video signal line are connected to one another and a second state that the drain and gate of the drive transistor and the video signal line are disconnected from one another, and a capacitor which is connected between a first constant potential terminal and the gate of the drive transistor, a reset circuit including a reset transistor and a reset switch connected in series between a second constant potential terminal and the video signal line, a drain of the reset transistor being directly connected to a gate of the reset transistor or connected to the gate of the reset transistor via the reset switch, a display element including a pixel electrode, a counter electrode connected to a second power supply terminal, and an active layer interposed between the pixel electrode and the counter electrode, and an output control switch connected between the drain of the drive transistor and the pixel electrode, comprising:

• sequentially selecting rows which the pixels form;
• executing a write operation on each of the pixels included in the selected row, the write operation including switching the connection state from the second state to the first state, making the video signal line driver output a video signal to the pixel via the video signal line, and switching the connection state from the first state to the second state while keeping the reset switch and the output control switch opened;
• and
• executing a reset operation every time before executing the write operation, the reset operation including disconnecting the video signal lines from the video signal line driver and closing the reset switch in each of the pixels while keeping the second state in each of the pixels.
