1. A light emitting signal generator, comprising:
an output stage circuit generating a light emitting signal according to a first control signal and a second control signal;
a first control signal generator coupled to the output stage circuit and a first control end and generating a first control signal at the first control end according to a reference light emitting signal, a first clock signal, a first reference voltage, and a second reference voltage;
a second control signal generator coupled to the output stage circuit and a second control end and generating a second control signal at the second control end according to the reference light emitting signal, the first clock signal, the first reference voltage, and the second reference voltage; and
a switch coupled between the first control end and the output stage circuit, wherein a control end of the switch receives the second reference voltage,
wherein in an output period, the switch is turned off to isolate the output stage circuit from the first control end.
