A display device according to the present disclosure includes: a pixel array unit () in which pixel circuits (A) are disposed in a matrix form, the pixel circuits each including a light emission unit (), a write transistor () that writes a signal voltage (Vsig) of a video signal, a retention capacitor () that retains the signal voltage (Vsig) written by the write transistor (), a drive transistor () that drives the light emission unit () on the basis of the signal voltage (Vsig) retained by the retention capacitor (), and an auxiliary capacitor () of which one terminal is connected to a source node of the drive transistor (); and a control unit () that provides a potential change to a source electrode of the drive transistor () by coupling through the auxiliary capacitor () to set an operation point of the drive transistor () as a cut-off region after the threshold value correction process.

Display device, method for driving display device, and electronic device

An electronic circuit that includes a plurality of first drivers coupled in parallel, the first drivers each including transistors coupled in series and transmitting data at a predetermined communication speed, and a second driver that includes transistors coupled in series and transmitting data at a communication speed lower than the communication speed of the first driver. The number of first drivers operating in parallel is sufficient for output impedance of the first drivers to meet a predetermined standard through application of an electrical potential to bodies of the transistors of the first drivers. The electrical potential causes an output level of the second driver to meet a predetermined standard.
