Abstract:
1. A scan driver for generating and transmitting at least two different types of scan signals to a display unit including a plurality of pixels, the scan driver comprising a plurality of sequence drivers, each of the sequence drivers comprising a plurality of shift registers for generating the at least two different types of scan signals, wherein one of the scan signals includes an initialization signal generated in one of the shift registers that is transmitted as an input signal of a next one of the shift registers and as an input signal of a pixel from among the plurality of pixels coupled to the one of the shift registers, and the one of the scan signals including the initialization signal is concurrently transmitted as an input signal to the shift register of one of the sequence drivers of a previous stage or a next stage adjacent to one of the sequence drivers including the one of the shift registers in accordance with a driving direction of the scan driver, wherein each of the plurality of sequence drivers of a stage among a plurality of sequence drivers comprises: a first shift register for receiving a forward direction start signal and the scan signal generated in the shift register of the sequence driver of the previous stage adjacent to the sequence driver of a corresponding stage, or the scan signal generated in the shift register of the sequence driver of the next stage adjacent to the sequence driver of the corresponding stage, and a backward direction start signal as a first input signal in synchronization with a first clock signal, and for outputting one of a second clock signal and a first power source voltage as a first scan signal respectively corresponding to the first input signal and a first initialization signal; and a second shift register for receiving the first scan signal as a second input signal in synchronization with the second clock signal and for outputting one of the first clock signal and the first power source voltage as a second scan signal respectively corresponding to the second input signal and a second initialization signal, wherein the first shift register comprises:
