PIXEL CIRCUIT, PIXEL CIRCUIT DRIVING METHOD, DISPLAY APPARATUS, AND ELECTRONIC DEVICE

摘要

Disclosed herein is a pixel circuit including: a light-emitting device; a constant current drive circuit configured to include a first transistor as a constant current source for supplying a predetermined current to the light-emitting device; and a switching circuit configured to include a second transistor for opening/closing electrical connection between a gate of the first transistor and a predetermined potential and connect the gate of the first transistor to the potential via the second transistor, thereby turning off the first transistor.
