Display device with idle periods for data signals

When an idle period is started, a voltage of the control signal is changed from a value H to a value L. As a result, the analog amplifiers provided in the signal line driver circuit are switched from the normal state to the low-driving power state. At this time, the data signal lines are set to have...

Summary:When an idle period is started, a voltage of the control signal is changed from a value H to a value L. As a result, the analog amplifiers provided in the signal line driver circuit are switched from the normal state to the low-driving power state. At this time, the data signal lines are set to have a constant potential. A gate voltage is changed from Vgh to Vgl at the same time as when the control signal was changed from the value H to the value L. As a result, the gate of each TFT returns to the OFF state from the ON state. The control signal remains at the value L until the idle period is over. In other words, when the next driving period is started, the voltage of the control signal is changed from the value L to the value H. As a result, the analog amplifiers in the signal line driver circuit are switched back to the normal state from the low-driving power state.
