Abstract

An 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.

Description

technical field [0001] The present invention relates to an emission driver, and more particularly to an emission driver comprising an n-type or p-type single transistor including an inverter circuit. Background technique [0002] The progressive light-emitting method is one of the driving methods of the organic light-emitting display device. The progressive light-emitting method refers to scanning data according to the sequentially applied scanning signal, and then making the OLED of the first scanned line according to the sequentially applied emission signal. The way the component starts to emit light. At this time, by adjusting the length of the section where no luminescent signal is applied, that is, the off duty ratio, a continuous dimming effect can be obtained, and it has the same effect as when a black belt is inserted, so motion blur can be eliminated. blur) phenomenon. [0003] However, when the light emission drive unit for supplying the above light emission sign...
