Abstract

Provided is a gate driver (120, 620, 1520, 1620). The gate driver (120, 620, 1520, 1620) includes a light emission driver (EDV) comprising a plurality of light emission stages (EST1, ..., EST32) cascaded and configured to output a plurality of light emission control signals (EM1, ..., EM32) on the basis of a light emission start signal (EVST) and a plurality of light emission clock signals (ECLK1, ECLK2) and an output controller (SCTR1, SCTR2) comprising a plurality of stages cascaded and configured to output a plurality of pull-up control signals (PUS1, ..., PUS4) and a plurality of pull-down control signals (PDS1, ..., PDS4) on the basis of the plurality of light emission control signals (EM1, ..., EM32), a plurality of clock signals (CLK1, CLK2), a plurality of control clock signals (CCLK1, ..., CCLK4), a first power source (VGH), and a second power source (VGL) having a lower voltage level than the first power source (VGH), wherein the plurality of stages each includes a carry part (CRY1, ..., CRY4) configured to output a carry signal (CR1, ..., CR4) on the basis of at least one of the plurality of light emission control signals (EM1, ..., EM32), at least one of the plurality of clock signals (CLK1, CLK2), the first power source (VGH), and the second power source (VGL) and an output part (OUT1, ..., OUT4) configured to output the pull-up control signal and the pull-down control signal on the basis of the carry signal (CR1, ..., CR4), at least one of the plurality of control clock signals (CCLK1, ..., CCLK4), the first power source (VGH), and the second power source (VGL).
