Display device having bootstrap circuit supplied with a precharge voltage

A display device comprising:

• a plurality of pixels;
• a bootstrap circuit including a first transistor including a gate electrode, a first electrode and a second electrode, a capacitor electrically connected between the gate electrode and the second electrode, and a second transistor electrically connected to the gate electrode;
• and
• a control circuit;
• wherein
• the bootstrap circuit is configured to electrically connect the second electrode to one of the plurality of pixels,
• in a first period when the bootstrap circuit is driven,
• the control circuit supplies a first analog voltage to the second transistor, supplies a precharge voltage smaller than a first analog voltage to the first electrode,
• the second transistor is turned on,
• the gate electrode is supplied with the first analog voltage,
• the first transistor is turned on,
• the gate electrode is supplied with the first analog voltage,
• the second electrode is supplied with a precharge voltage smaller than the first analog voltage from the first electrode,
• in a second period after the first period when the bootstrap circuit is driven,
• the second transistor is turned off,
• the first electrode is supplied with a second analog voltage,
• the capacitor supplying a third analog voltage to the gate electrode in response to the first analog voltage and the second analog voltage, and
• the first transistor supplies the second analog voltage from the first electrode to the second electrode.
