Abstract: In one aspect, an emission driving unit and an organic light emitting diode (OLED) display having the same are disclosed. The emission driving unit includes an input signal generating circuit that receives a FLM signal according to a first clock signal, receives a second clock signal according to the FLM signal, and outputs a sequential input signal. The emission driving unit also includes an inverter circuit that receives the FLM signal according to the first clock signal, and that inverts the FLM signal to generate an inverter output signal. The emission driving unit also includes an output switching circuit that outputs a first voltage having a logic high level or a second voltage having a logic low level as an emission signal in response to the inverter output signal. The input signal generating circuit, the inverter circuit, and the output switching circuit are implemented by transistors of the same kind.
