Emission control driving circuit, emission control driver and organic light emitting display device

An emission control driving circuit, comprising:

• a first gate voltage control circuit, generating a first gate-controlled voltage at a first gate voltage control node according to signals of a first input terminal, a second input terminal and a second power input terminal;
• a second gate voltage control circuit, generating a third gate-controlled voltage at a third gate voltage control node according to the first gate-controlled voltage and the signals of the first input terminal, the second input terminal, a third input terminal, a first power input terminal and the second power input terminal;
• and
• an isolation circuit connected to the second power input terminal, the first gate voltage control circuit and the second gate voltage control circuit;
• wherein
• when the first gate-controlled voltage is lower than a voltage value of the second power input terminal, the isolation circuit isolates the first gate voltage control node from the first gate voltage control circuit and/or the second gate voltage control circuit;
• or
• when the third gate-controlled voltage is lower than the voltage value of the second power input terminal, the isolation circuit isolates the third gate voltage control node from the first gate voltage control circuit and/or the second gate voltage control circuit.
