Abstract
A gate driving circuit includes a shift register configured to generate a plurality of output signals based on at least one clock signal, a plurality of output buffers configured to generate a plurality of gate signals by amplifying the output signals and to sequentially output the gate signals to a plurality of gate lines in a display panel, a detector configured to sequentially sense the gate signals and to compare each of the gate signals to a reference voltage, and a dummy output buffer configured to be coupled between the shift register and a gate line of the gate lines instead of an output buffer of the output buffers when a voltage level of a corresponding gate signal from the output buffers is less than a voltage level of the reference voltage.
