Light-emitting signal control circuits

摘要

One embodiment of the present invention discloses a light-emitting signal control circuit comprising: a first driving transistor for allowing a voltage to be output from a first voltage source to a output end under the control of a low level drive signal; a second driving transistor for allowing a voltage to be output from a second voltage source to the output under the control of a second low level drive signal; a first transmission control transistor connected between the first voltage source and the control end of a first driving transistor; a control signal unit for generating the first low level drive signal and the second low level drive signal; a voltage stabilizer connected between the second low level drive signal and first transmission control transistor. The circuit will suppress the voltage fluctuation on the control end of the first transmission control transistor.
