SHIFT REGISTER

摘要

PURPOSE: A shift register is provided to supply full driving signal to gate lines during a full driving period and successively supply scan pulses to the gate lines to a right direction or a reverse direction during a scanning period. CONSTITUTION: Scan pulse output units(SC1 to SC3) output scan pulses to gate lines. A carry pulse output unit(CO) supplies carry pulses to a front step stage and a rear step stage. A first node control unit(NC1) controls the voltage state of a set node and a reset node. A second node control unit(NC2) controls the voltage state of a control node.
