Comparator unit, display, and method of driving display

A display comprising:

• a plurality of pixels arranged in a two-dimensional matrix, the pixels each including a light-emission section and a drive circuit configured to drive the light-emission section, such that there are a plurality of light emission-sections,
• the drive circuit including
• a comparator section configured to compare a control pulse with an electric potential based on a signal voltage, and to output a predetermined voltage based on a comparison result, and
• a light-emission section driving transistor configured to supply a current to the light-emission section in response to the predetermined voltage from the comparator section, thereby allowing the light-emission section corresponding to the drive circuit to emit light, and
• the comparator section including
• a signal writing transistor configured to receive the signal voltage, an inverter circuit, and a capacitor configured to include an input point and an output point, and compares a voltage of the output point with a predetermined voltage,
• control circuitry configured to receive the control pulse, and to perform ON-OFF operation based on a signal of a phase opposite to a phase of a signal used by the signal writing transistor, and
• the capacitor is configured to retain, based on operation of the signal writing transistor, the electric potential based on the signal voltage.
