Abstract:
1. A scan driver, comprising: a plurality of stages, each of the stages including a first signal processor and a second signal processor, the stages to simultaneously output first scan signals and to sequentially output second scan signals during a frame period, wherein: the first signal processor is coupled to an input terminal, a first clock terminal, a third clock terminal, an auxiliary terminal, a first power source terminal, and a second power source terminal, and the first signal processor is to output a first output signal and a second output signal to the second signal processor through a first node and a second node, respectively; and the second signal processor is coupled to a second clock terminal and the first power source terminal and receives the first output signal and the second output signal through the first node and the second node, respectively, and the second signal processor is to output the first scan signal and the second scan signal to an output terminal, wherein the output terminal is coupled to a pixel and the input terminal of the first processor of a succeeding one of the stages, and wherein: the first scan signals are to be supplied during a first driving mode during the frame period and the second scan signals are to be supplied during a second driving mode during the frame period, the first driving mode is to be performed before the second driving mode, and pixels of a display are to store data for light emission during the second driving mode, wherein the frame period includes a simultaneous driving period corresponding to the first driving mode, an initializing period, and a progressive driving period corresponding to the second driving mode, and wherein, in the simultaneous driving period, clock signals are supplied and maintained to the first clock terminal, the second clock terminal, and the third clock terminal, an auxiliary signal is supplied to the auxiliary terminal, and a second power source is supplied to the second power source terminal, the second power source having a high level voltage.
