    Abstract: An electronic device includes a display panel including pixels respectively connected to scan lines, scan stages corresponding to the scan lines, where each of the scan stages receives a carry signal, and outputs a scan signal, masking circuits electrically connected to some of the scan stages, respectively, where each of the masking circuits outputs a masking carry signal in response to a masking signal and the scan signal, and transmission circuits electrically connected to others of the scan stages, respectively, where each of the transmission circuits outputs the scan signal output from a corresponding scan stage among the scan stages. A j-th (j is an integer greater than 1) scan stage among the scan stages receives one of the scan signal output from a (j−1)-th scan stage and the masking carry signal as the carry signal.

    Abstract: An emission driver includes a plurality of stages. Each stage includes an input block that transfers an input signal to a control node, a control block that controls an inverted control node and applies a third low gate voltage to the inverted control node in response to a voltage of the control node, an emission signal output block that outputs a high gate voltage as an emission signal in response to the voltage of the control node and outputs a first low gate voltage as the emission signal in response to a voltage of the inverted control node, and a carry signal output block that outputs the high gate voltage as a carry signal in response to the voltage of the control node and outputs a second low gate voltage different from the first low gate voltage as the carry signal in response to the voltage of the inverted control node. The third low gate voltage is different from the first low gate voltage and the second low gate voltage.
