Abstract
Provided are a GIP driving circuit and a display device using the same. The GIP driving circuit includes: a plurality of stages which sequentially receives a phase-delayed clock and sequentially generates an output. An nth stage (n is a positive integer) includes: a first switch Treceiving a carry signal from an n−1th stage and controlling a QB node to a low voltage and a Q node to a high voltage when the carry signal has a high voltage; a second switch Treceiving a carry signal from an n+1th stage and controlling the QB and Q nodes high and low voltages, respectively, when the carry signal has a high voltage; a plurality of inverters connected between nodes Q and QB and constituting a latch; and a buffer outputting a clock as an output voltage when a voltage of the Q node is a high voltage and output.
