Abstract

The present application discloses a light emitting circuit, a backlight module and a display panel. The light emitting circuit includes a light emitting device, a driving transistor, a data signal writing module, a first control module, a bistable circuit module, and a second control module. The first control module, the bistable circuit module, and the second control module work together to control a potential reversal of a gate of the driving transistor. By setting a bistable circuit module in the light emitting circuit, the present application can quickly change the potential of the gate of the driving transistor, so as to accurately control the luminous time of the light emitting device.
