GATE DRIVING CIRCUIT AND DISPLAY APPARATUS HAVING THE SAME |
摘要 |
A gate driving circuit includes stages, the stages being cascaded and each including: a pull-up part which pulls up a gate voltage to a clock signal during a horizontal scanning period (1H); a carry part which pulls up a carry voltage to the clock signal during the horizontal scanning period (1H); a pull-up driving part connected to a control terminal (Q-node) common to the carry part and the pull-up part and which receives a previous carry voltage from a first previous stage to turn on the pull-up part and the carry part; and a ripple preventing part which prevents a ripple generated at a previous Q-node of a second previous stage based on a ripple generated at the Q-node of the carry part and the pull-up part.
