Abstract
A light-emitting circuit is provided herein, which includes a light-emitting unit, a driving transistor, and a bypass transistor. The driving transistor is configured to drive the light-emitting unit. The bypass circuit diverts the current flowing from the driving transistor to the light-emitting unit for reducing the possibility of the light-emitting unit illuminating in the dark state.
