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

摘要

PROBLEM TO BE SOLVED: To enhance the image quality of a display apparatus for driving light-emitting devices by constant current PWM drive.

SOLUTION: A pixel circuit including: a constant current drive circuit configured to include a first transistor as a constant current source for supplying a predetermined current to a light-emitting device; a second transistor configured to open/close electrical connection between the first transistor and the light-emitting device; and a switching circuit configured to switch between an on state and an off state of the second transistor by controlling a gate voltage of the second transistor. The present art is applicable to, for example, a display apparatus.
