Abstract

The invention provides a light-emitting signal control circuit and relates to a control circuit. The light-emitting signal control circuit comprises a first driving tube, a second driving tube, a first transmission control tube, a control signal unit and a voltage stabilizer, wherein the first driving tube is used for outputting voltage of a first voltage source to an output end under control of a first low level driving signal; the second driving tube is used for outputting voltage of a second voltage source to the output end under control of a second low level driving signal; the first transmission control tube is connected between the first voltage source and a control end of the first driving tube and used for generating a high level driving signal under the action of the second low level driving signal so as to cut off the first driving tube; the control signal unit is used for forming first low level driving signals and second low level driving signals according to a set of input control signals; the voltage stabilizer is connected between the second low level driving signal and a control end of the first transmission control tube and used for stabilizing the second low level driving signal. According to the light-emitting signal control circuit, fluctuation of voltage at the control end of the first transmission control tube becomes low, so that stabilization of the light-emitting signal control circuit is facilitated.

Description
